Mental health first aid for eating disorders: pilot evaluation of a training program for the public

Participants

A desired sample size of n = 84 was calculated based on a power analysis which assumed that, given no correlation between baseline and post-training scores, a sample of 64 participants would give 80% power to detect a medium effect size (d = 0.5) from baseline to post-training with alpha = 0.05 (Sample Power 2.0). This was increased to n = 84 to allow for 30% drop-out (n = 20) between baseline and follow-up.

Participants were recruited from the residential halls and colleges affiliated with The University of Melbourne; a large metropolitan campus with a diverse student population [43]. All undergraduate students residing on campus were eligible to participate. These young adults were chosen for convenience sampling because they represent a group at very high risk of developing an eating disorder [44, 45], and a group who, given the nature of their residential environment, is likely to require skills in providing mental health first aid [46, 47]. Welfare staff from campus residences were also included in the sample, as they were able to provide support to students who received the training, and were likely to be in contact with any individuals receiving treatment for an eating disorder.

Recruitment advertisements were posted as flyers on noticeboards around residences, presented orally at dinner meetings, or written in weekly news emails. The advertisements included information about eating disorders and MHFA training. Student and staff training sessions were run separately. Approval for this research was granted by the University of Melbourne Human Research Ethics Committee.

Intervention

The training intervention was a 4-hour single-session, classroom-style, education program designed to be presented to groups of between 5 and 15 people. It included didactic teaching using a Powerpoint presentation, small-group learning activities (in pairs or threes) and whole-group discussion components. A teaching manual was developed to guide facilitation and ensure fidelity. Training was delivered by one primary instructor with a second facilitator assisting with group activities and participant questions. Both were trained and accredited MHFA Instructors [38].

Measures

An assessment battery, including a range of self-report questionnaires, was designed to measure change in knowledge, attitudes and behaviours about eating disorders, as well as gather information about the demographic characteristics of participants and their mental health status.

Knowledge of eating disorder symptoms was assessed with a single item that asked participants to give a brief description of what you think the main signs or symptoms of an eating disorder might be. The open-ended responses were scored against the 25 ‘warning signs of a developing disorder’ outlined in Eating Disorders: First aid guidelines[48]; one point was awarded for each warning sign mentioned. The inter-rater reliability for scoring items was r = 0.94. This research was the first implementation of this measure.

Accurate problem recognition, knowledge of effective treatments and interventions, and attitudes towards bulimia, were assessed using the Mental Health Literacy Questionnaire for Bulimic Type Eating Disorders (MHLQ-B). The MHLQ-B was developed for the Health and Well-Being study by Mond and colleagues [49] and has been widely used in the study of eating disorder mental health literacy. The questionnaire begins with a vignette describing a fictional young adult woman ‘Kelly’ whose symptoms meet DSM-IV-TR diagnostic criteria for bulimia purging subtype.

A knowledge of effective treatments and professionals scale was constructed from the three questions on the MHLQ-B assessing knowledge of individuals who might be helpful (15 items), knowledge of treatments or activities (16 items) and knowledge of medications (eight items). Seven items were selected to construct the scale, based on the evidence in the current treatment literature, and the recommendations in the Eating Disorders: First aid guidelines[48], which suggest that psychologists, psychiatrists, dietitians/nutritionists, GPs, CBT, getting advice about diet and nutrition, and antidepressants, are all effective for eating disorders, and can therefore be considered ‘helpful’ for bulimia. Hence, participant responses were scored from zero (none of these items rated as ‘helpful’) to seven (all items rated as ‘helpful’). Although this approach has been used to assess knowledge of treatments for depression in previous evaluations of MHFA training [50], this research was the first time this measure had been used to assess knowledge of effective treatments and professionals for eating disorders.

A novel addition to the analyses of the MHLQ-B was the inclusion of the knowledge of informal help-seeking scale. Because there are informal activities known to facilitate formal treatment seeking or the management of disordered eating symptoms, the current research also sought to quantify how knowledge about broader help-seeking activities changes in response to the training program. From the 40-item list of individuals, treatments or activities, and medications, provided in the MHLQ-B, those that were recommended in the Eating Disorders: First aid guidelines[48], as appropriate and helpful, were used to construct the scale: friends, family members, using a self-help treatment manual and getting information about problem eating and available services. Hence, participant responses were scored from zero (none of these items rated as ‘helpful’) to four (all items rated as ‘helpful’).

The First Aid Knowledge Test (FAKT) was developed for use in the current research to test participant knowledge of best practice first aid strategies, as outlined in Eating Disorders: First aid guidelines[48]. It contains 26 true/false statements regarding knowledge and behaviours required for providing optimal mental health first aid. Responses are via a single forced-choice selection from the options: ‘Agree’, ‘Disagree’ or ‘Not sure’. One point is given for each answer that concurs with the information in the guidelines (i.e. an ‘agree’ response in relation to a true statement), resulting in a possible total score range of 0-26. The measure was validated with pilot testing.

The Social Distance Scale assesses levels of social rejection that members of the community are likely to impose on individuals with mental illness [51]. It comprises seven questions that ask how likely a participant is to react to a person with mental illness, as described by an accompanying vignette. Each question is rated on a 4-point Likert scale (1 = ‘definitely willing’ to 4 = ‘definitely unwilling’) [52]. A composite measure of social distance is calculated by adding across all items, with higher scores indicating a greater degree of desired social distance and more negative attitudes towards people with mental illness. In the current research possible total scores ranged from 0-35.

The Level of Contact Report [53] measures how familiar members of the public are (what level of contact they have) with individuals with mental illness. It was developed to examine whether level of familiarity had any effect on stigmatising attitudes, such as perceiving a person with schizophrenia as dangerous or unpredictable. The instrument lists 12 situations involving contact with an individual with mental illness. The highest score reported by a participant is taken as the total score. In the current research all items were modified to be specific to eating disorders, such that all references to ‘mental illness’ were replaced with ‘eating disorder’.

Throughout the questionnaire battery, six items were included to assess participants’ provision of mental health first aid to individuals with eating disorders, knowledge of the MHFA action plan and confidence in providing assistance. They were: (1) In the last 6 months have you had contact with anyone who you think might have an eating disorder? (2) If ‘yes’, how many? (3) If you have had contact with someone who has an eating disorder, in the last 6 months, have you offered them any help? (4) If you offered help, what type of help was it? (5) If Kelly was someone you knew and cared about, how would you help her? (6) If you had contact with someone who had a problem like Kelly’s, how confident would you feel in helping them? The items were based on those used in previous MHFA training evaluations [50, 54–56]. Items 1, 3 and 6 required forced-choice responses, while items 2, 4 and 5 were open-ended. Responses to item 4 were coded into one of nine categories according to recurring themes. Category frequencies were then assessed across time points. Responses to item 5 were scored against the six components within the MHFA action plan (see Figure 1). Because the first action A – approach the person, assess and assist with any crisis contained many concepts, this was split into two categories (approach and assess/assist). The remaining four actions comprised one category each. For each of the six categories, responses were scored out of two points: a score of two was given if participants correctly described an action and provided specific detail about how they would undertake that action; a score of one was given if they mentioned the action but did not provide detail on how it may occur; and a score of zero was given if the action was not mentioned. A total score was calculated by adding together the scores for each of the categories, with a possible total score falling between 0-12. The inter-rater reliability on these items was r = 0.91. This scoring system has been used in previous research investigating MHFA action plan knowledge [40, 57].

The First Aid Experiences Questionnaire was developed by Jorm, Kitchener and Mugford [56] for a follow-up study of participants who had attended MHFA training. It is designed to elicit open-ended information about helping behaviours towards individuals with mental health problems and about what the perceived effect of those behaviours was. The questionnaire has also been used in research investigating the utility and impact of accessing MHFA guidelines on the internet [58]. To assess whether the information provided in the training program was generalised to illnesses other than eating disorders, the questionnaire also asked whether participants had provided first aid to individuals who were experiencing mental health problems other than an eating disorder.

Given that some previous research has found that providing preventive interventions, which describe eating disorder symptoms, can lead to increases in eating pathology [59, 60]The Eating Disorders Examination Questionnaire (EDE-Q) [61] was used in the current research to assess for any negative impact on participants’ eating pathology. The EDE-Q is currently considered the gold-standard for eating disorder research [62–66]. Australian research suggests that a global score of 2.8 reliably predicts clinical eating disorder status in females [65], however, a reliable cut-off has not yet been established for males.

The K10, a general measure of non-specific psychological distress, was also used to assess for any negative impact on participant psychopathology. Total scores range from 10-50, with higher scores indicating a higher level of distress [67].

Design and analyses

Repeated measures ANOVAs were used for continuous measures completed at all three time points. Where assumptions of sphericity where violated, the Hunyh-Feldt method for adjusting degrees of freedom was used [68]. Where the omnibus test was significant, planned contrasts were conducted to assess whether there was a significant change from baseline to post-training and baseline to follow-up. Dependent (paired) samples two-tailed t-tests were used for continuous measures completed at baseline and follow-up only. For ordinal data, Friedman’s ANOVA was used and Wilcoxon signed-rank tests were then conducted where the omnibus test was significant [68, 69]. For dichotomous data, a Cochran’s Q test was used for k samples and the McNemar test for paired comparisons [68, 69]. A Pearson’s chi-square analysis was conducted in the assessment of whether there were differences in first aid experiences between staff and students in the sample, because these groups were independent. Unless corrections for inflated error rate were required, all tests were conducted using α < .05. For open-ended responses, thematic analysis was used to section data into commonly occurring categories, which could then be assessed for frequency.

Procedures

Prior to attending the training program, participants were sent an electronic link to the baseline questionnaire, hosted by an online survey software system (surveymonkey.com). Immediately after the training, participants completed the post-training questionnaire and an electronic link to the follow-up questionnaire was sent to each participant’s email address 182 days (6 months) after the date of attendance at the training program. Personalised email and SMS text prompts were sent at one week intervals, for a maximum of three weeks, to remind participants to complete the questionnaire.

Participants

Participant flow

Flow of participants through the research stages is shown in Figure 2. Ninety-one percent of the 90 participants who completed the baseline questionnaire went on to complete the training and the post-training questionnaire. No statistically significant differences were found at baseline between those participants who completed the training and the post-training questionnaire and those who did not. Eighty-one percent of baseline participants went on to complete all three questionnaires. There were also no statistically significant differences found at baseline between those participants who completed the follow-up questionnaire and those who did not. Because of the small number who failed to complete all three stages of the evaluation (n = 17), and the lack of any significant difference between completers and drop-outs, the participants who did not complete the post-training or follow-up questionnaires were excluded from further analyses.

Knowledge

When asked what they thought was ‘Kelly’s main problem’ the majority of participants recognised the symptoms in the vignette as relating to a general mental health problem such as ‘low self-esteem or lack of confidence’ or ‘mental illness’. Although many correctly recognised Kelly’s problem at baseline as ‘bulimia nervosa’, the proportion increased significantly from baseline to post-training. However, this dropped at follow-up and was no longer significantly different from baseline. To assess whether recognition of the problem as any eating disorder changed over time, the proportion of participants responding ‘bulimia nervosa’, ‘a binge eating disorder or problem’ or ‘anorexia nervosa’, were assessed together. The proportion recognising the problem as any eating disorder increased significantly from baseline to post-training, and despite a fall at follow-up, was still significantly different to baseline levels. To assess whether recognition of the problem in the vignette, as a general mental health problem, changed over time, the frequency of all other responses representing a mental health related condition were assessed together (‘an anxiety disorder or problem’, ‘mental illness’, ‘depression’, ‘low self-esteem or lack of self-confidence’). There was a significant decrease in frequency from baseline to post-training and this was maintained at follow-up.

At baseline, participants scored an average of 4.7 points out of 7 on the Knowledge of effective treatments and professionals scale. Scores were significantly different across time points, with both post-training and follow-up scores being significantly higher than baseline. On the Knowledge of informal help-seeking scale participants scored an average of 2.8 out of 4. Again, scores were significantly different across time points, with post-training scores being significantly higher than baseline, however, after a decline in scores at follow-up these were no longer significantly different from baseline.

At baseline participants scored an average of 16.1 of a possible 26 on the FAKT. Scores were significantly different across time points, with both post-training and follow-up scores a significant improvement on baseline.

The fifth Mental Health First Aid item asked participants how they would help someone like Kelly. Average ALGEE action plan scores were significantly different across time points, however, while post-training scores were a significant improvement on baseline, this was not maintained at follow-up and scores were no longer significantly different from baseline.

Attitudes

Results for the instruments assessing participant attitudes are also shown in Table 4. Scores on the Social Distance Scale remained stable and were not significantly different across time points. Participant attitudes towards bulimia were assessed via three items on the MHLQ-B. Responses to the first item How distressing do you think it would be to have Kelly’s problem? showed that a large majority of participants (>90%), across all three time points, believed it would be either ‘very’ or ‘extremely’ distressing to have Kelly’s problem. Although the percentage of participants who believed it would be extremely distressing, increased from 38% at baseline to 40% at post-training, then to 44% at follow-up, the ombnibus significance test found no significant differences in scores over time.

Responses to the item How sympathetic would you be towards someone with Kelly’s problem? revealed that the majority of participants, across all three time points, believed they would be ‘very’ or ‘extremely’ sympathetic towards someone with Kelly’s problem. Significant differences were found in responses over time. However, while there was a significant change in ratings from baseline to post-training, a comparison of baseline and follow up revealed no significant change. That the ratings of ‘extremely’ increased and ratings of ‘moderately’ decreased from baseline to post-training, though returned to baseline levels at follow-up, may have largely accounted for this finding.

Responses to the item Have you ever thought it might not be too bad to be like Kelly, given that she has been able to lose a lot of weight? showed that majority of participants reported that they had ‘never’ or ‘rarely’ thought it desirable to be like Kelly. These responses appeared stable over time and an omnibus test revealed no significant differences in ratings across the time points.

Behaviours

In response to the question In the last 6 months have you had contact with anyone who you think might have an eating disorder? 60% said ‘yes’ at baseline. The modal number of contacts was 1 person (n = 19), and the total number of contacts reported by participants was 78. At follow-up, despite a small drop in the frequency of participants reporting that they had contact with someone with an eating disorder (56%), the modal number was 2 people (n = 16), and the total number of contacts was 97. Twenty-two participants reported an increase in the amount of contact across time. These changes, however, were not statistically significant. In addition, no statistically significant changes were found between baseline and follow-up for the items assessing the amount of assistance given and the type of assistance given.

Results for the final Mental Health First Aid question regarding participant confidence revealed that confidence ratings were significantly different across time points, with both post-training, and follow-up ratings being significantly higher than baseline.

Mental health status

A statistically significant reduction in the mean EDE-Q global score was found between baseline (M = 1.2) and follow-up (M = 1.1), indicating a reduction in eating disorder psychopathology t(72) = 2.27, p = .026.

The mean total K10 score dropped slightly from baseline (M = 18.1) to follow-up (M = 17.2), though no statistically significant differences were found across the two time points t(72) = 1.53, p = .129.

Changes in knowledge

There was no significant change in the knowledge of eating disorder symptoms across time. It is possible that this finding is the result of participants lodging less detailed or less specific answers across time, as the follow-up questionnaire was sent to the majority of participants between October and November; a busy exam period and the end of the academic year. It is also possible that the training failed to produce a significant increase in knowledge scores over time because there was not enough emphasis placed on eating disorder specific signs and symptoms throughout the curriculum. In fact, the training emphasises the importance of recognising the development of non-specific signs of distress, as this is the best opportunity to provide timely mental health first aid. As such, participants were taught to look for a change in “a person’s thinking, emotional state and behaviour, which disrupts the ability to work or carry out other daily activities and engage in satisfying personal relationships” [27], which is how the MHFA program defines the onset of a mental health problem. Future evaluations may therefore benefit from an item designed to measure a change in knowledge regarding the most appropriate time to provide mental health first aid, rather than specific knowledge relating to the wide range of eating disorder signs and symptoms.

Unlike knowledge of signs and symptoms, accurate recognition of the problem in the MHLQ-B vignette, as ‘bulimia nervosa’, increased significantly immediately after the training. Furthermore, recognition of the problem as any eating disorder also increased, and this change was sustained over time. Importantly, this effect of increased recognition, was not generalised to any mental health problem; participants were not more likely to label the problem in the vignette with general terms relating to mental ill-health at follow-up, indicating that the improved recognition was specific to eating disorders, and in particular to bulimia. It is interesting that participants’ increased recognition of the problem as any eating disorder was more robust than the specific recognition of the problem as bulimia. Given that the training encourages participants to look for changes in eating and exercise behaviours that are interfering with function, rather than encouraging participants to look for indicators of diagnostic categories, this result is perhaps more desirable than having a sustained increase in the specific recognition of the problem as bulimia.

The Knowledge of effective treatments and professionals scale in the MHLQ-B showed that participants’ knowledge of effective treatments for eating disorders also significantly improved over time. Unfortunately this was not true for the Knowledge of informal help-seeking scale. While it was found that total scale scores significantly improved after the training, these improvements were not maintained at follow-up. This result, however, is perhaps not unexpected. While the treatment literature recognises the importance of friends and family in the help-seeking and recovery process, it is also apparent that the social network can have a negative influence on the development of mental illness and barriers to care [72, 73]. It is therefore true that the effectiveness of individuals in facilitating help-seeking and recovery will depend on their level of knowledge, skill and empathy. As this concept was discussed as part of the training, it is perhaps not a surprise that ‘helpful’ ratings did not change across time. It is also important to acknowledge that this study is the first time the Knowledge of informal help-seeking scale had been implemented. Given its construction from just 4-items, further testing of its psychometric properties would further elucidate its utility in future evaluations of MHFA training. Furthermore, future evaluations may benefit from an examination of changes to inappropriate informal help-seeking, rather than a narrow focus on changes in the small number of appropriate strategies.

The FAKT showed that participant knowledge of first aid skills improved significantly after the training and, despite a drop-off in the follow-up period, this improvement was maintained at follow-up, indicating that the training was associated with a gain in knowledge that was sustained over time. As this is the first time the FAKT instrument has been implemented, the psychometric properties are not well known. It is therefore possible that increases from baseline to post-training were the result of re-test effects. However, given that there was a small drop in knowledge from post-training to follow-up, it appears that each re-testing event does not necessarily result in ongoing improvement over time.

Responses to the Mental Health First Aid item, which asked participants how they would help ‘someone like Kelly’, indicated that the training was associated with a significant increase in knowledge of the appropriate actions a person should take when providing a first aid intervention, as outlined by the MHFA action plan. However, this change was not sustained over time. There are two possible explanations for this result. One is that, given the open-ended response format for this item, participants provided less detailed responses at follow-up, due to their academic time constraints, and hence scored more poorly than at post-training. Another plausible explanation is that the training was insufficient in duration to produce a lasting effect. It is perhaps not unsurprising that participants could not remember these five specific actions, six months after receiving a 4-hour intervention. Furthermore, given that a previous evaluation of the full MHFA training program found an increase in knowledge of the action plan, which was maintained at six month follow-up [57], it is likely that had the current training involved more time to discuss and role-play the action plan, retention of information would have been maintained over time.

Overall, results for the items assessing knowledge showed that the training was associated with an immediate and lasting improvement in eating disorder problem recognition, knowledge of effective treatments, and consensus-based first aid strategies. Although results showed that there were increases in knowledge for informal help-seeking strategies and the MHFA action plan, these changes were not maintained over time, perhaps indicating that the intervention was too brief to produce lasting effects. These results do however provide preliminary support for the impact MHFA training can have on mental health literacy for eating disorders.

Changes in attitudes

Scores on the Social Distance Scale remained unchanged after the training and during the follow-up period, compared to baseline. Interestingly, in a review performed by Jorm and Oh [74], interventions aimed at reducing stigmatising attitudes of similar length to the current training, were found to have similar results whereby no significant changes in the total score were found over time. It therefore appears that the current intervention may have been too short and required more direct contact with people affected by eating disorders, to achieve the desired reduction in social distance.

The MHLQ-B item assessing participant ratings of how distressing they believed Kelly’s problem would be, found that there were no significant differences associated with the training, despite some small fluctuations in ratings. Two plausible explanations for this result can been considered. First, it is possible that there was an insufficient ‘dosing’ effect, whereby the intervention was too short to provide lasting effects over time. If this were true, a longer intervention or booster session should produce the desired result. The second possibility is that participants were at ceiling when first measured at baseline. Given the high proportion of participants who rated Kelly’s problem as either ‘very’ or ‘extremely’ distressing, it is possible that the intervention was unable to produce any further increase. As a point of comparison, a community-based survey of adolescent girls’ mental health literacy for eating disorders found that most respondents believed that it would be ‘very’ (40.0%) or ‘extremely’ distressing (45.0%) to have a problem like Kelly’s, indicating that there was little need for an intervention to educate participants about the distressing nature of the condition [75].

The desirability of bulimic symptoms was also assessed with a MHLQ-B item, which found that the majority of participants reported that they had ‘never’ or ‘rarely’ thought that ‘it might not be too bad to be like Kelly given that she has been able to lose a lot of weight’. This finding is in contrast to previous evaluations of MHLQ-B, which have found much higher levels of desirability. The current finding may be an artefact of older adults and male participants being included in the sample, rather than a non-representative sample per se. That the desirability ratings remained stable over time and showed no significant change after the training, can be explained in two ways. First it is possible that the training had no effect on how desirable participants found bulimic symptoms. However, it is also possible that there was a ceiling effect. Given that it is expected the intervention would have the strongest effect among participants who considered bulimia desirable, though most did not indicate any desirability for bulimic symptoms at baseline, the beliefs of the current sample left little room for improvement.

Taken together, items assessing attitudes towards bulimia indicate that the sample at baseline were already empathic. It is therefore difficult to infer from these results whether the intervention was effective in changing attitudes about eating disorders. Although a sample with less empathic attitudes at baseline may have shown a statistically significant improvement after training, it remains a welcome finding that members of the community already express empathic attitudes towards individuals with eating disorders.

Changes in behaviour

The amount of contact participants had with individuals with eating disorders was measured using the Level of Contact Report and two Mental Health First Aid questions. Across all measures, there were no significant differences found between the amount of contact with individuals with eating disorders before the training and the amount of contact after the training. One possible explanation for this finding is that the environment in which the participants studied, worked and resided, was not amenable to producing a change in the amount of contact a participant may experience. For example, the large majority of students and staff undertake residence at a college for an academic year, beginning at the start of March and ending in late November. Between these months, there is very little change in the composition of staff or students in the residences. In the current study, the baseline measurement, training and follow-up period all fell within the 2010 academic year. Furthermore, because college residences are an environment where individuals live in very close contact with one another, and the welfare of students is closely monitored by pastoral care teams, it is possible that the majority of individuals with eating disorders, who were present within the residences, were already identified at baseline and this number could not be significantly improved upon after the training and during the follow-up period. Another possible explanation for the non-significant change in contact is that the training intervention had no effect on participant behaviour toward those with eating disorders. However, given that there was a significant increase in the ability to accurately recognise an eating disorder, that knowledge of effective first aid strategies significantly increased, and there was no increase in social distance, it appears unlikely that the intervention would not influence contact to some degree. A second and longer follow-up period, crossing over more than one academic year, may elucidate any effect of the college environment on the level of contact found among participants. However, it should be noted that some previous evaluations of MHFA training have also recorded no change in the level of contact with those with mental illness [50, 54].

The third Mental Health First Aid item was designed to measure change in the amount of help provided to those with eating disorders. No significant increase was found after the training. Some previous MHFA training evaluations have also failed to find an increase in amount of help provided. Of the four studies that have used the same method of evaluating help provided, two studies found no significant differences between baseline and follow-up [56, 76].

The current study also found no change in the type of help provided by participants. Given the relatively small number of participants who reported providing first aid, it is possible that there was inadequate power to detect an effect. This postulate is supported by the finding that the majority of participants who provided first aid reported that they had done things differently to before they received the training, according to responses on the First Aid Experiences Questionnaire. Furthermore, the training was associated with a significant increase in participant confidence in providing first aid. In combination then, these results suggest that if a second and longer follow-up testing period was employed, which would allow participants more time to be in contact with and provide assistance to individuals with eating disorders, the existence of any significant changes in behaviour after the training, would be clarified.

Responses to the First Aid Experiences Questionnaire were largely positive, as many indicated that the training allowed them to feel more knowledgeable, confident and better prepared to recognise and provide assistance to someone developing or experiencing an eating disorder. Although the quantitative measures found no statistically significant increases in the amount of help provided, the open-ended information gathered by this instrument suggests that participants approached someone they were concerned about with more empathy and patience than before, and that this change was a result of the training. Furthermore, the majority of those who had not provided first aid indicated that the training had impacted on the way they viewed eating disorders as mental illnesses worthy of care, understanding and effective treatment. Interestingly, it appeared that the training generalised to assisting individuals with other mental health problems, as an equal proportion of participants reported providing first aid to individuals with mental illnesses other than eating disorders.

Participants who had provided first aid reported feeling reasonably successful in their intervention, however, many went on to explain that the unresolved nature of the person’s illness contributed to their sense that their intervention was not a complete success. Given that this finding reiterates that of the earlier evaluation of guidelines being downloaded from the internet [58], future MHFA training would do well to include a discussion of what ‘successful’ first aid might look like and how participants should not expect immediate or necessarily complete recovery, as a result of providing assistance and facilitating appropriate treatment seeking. Interestingly, a much larger proportion of participants who reported assisting someone with another mental health problem reported feeling that their first aid intervention was successful. The ambivalence about success may therefore be particular to assisting in the case of an eating disorder.

Importantly, the First Aid Experiences Questionnaire provided no reports of adverse experiences associated with an attempted first aid intervention. Conversely, participants indicated that as a result of their suggestion and assistance, seven individuals had sought help for their suspected eating disorder, and an additional three were better supported whilst already receiving care. Furthermore, three participants mentioned assessing for suicide risk where they wouldn’t have done so before the training. While statistical inferences from these data are not possible, it is encouraging that these responses indicate the training was associated with a higher level of effective assistance, and ultimately, more appropriate help-seeking.

In sum, the findings from instruments measuring behavior change suggest that there is some limited evidence for a change in first aid behaviours and an increase in appropriate help-seeking, albeit among a small number of participants. Many of the findings in the current research confer with those of previous MHFA evaluations employing a six month follow-up period, which suggests that a second and longer follow-up period, for example at 12 months after training, might allow for an increase in the size of the sample providing assistance, and thereby an increase in the power to detect any statistically significant effect of the training on behaviour change.

Changes in mental health

The EDE-Q and K10 were implemented to assess any changes in the mental health of participants. Given previous research evaluating preventive interventions for eating disorders has found that providing information about eating disorder symptoms can lead to an increase in eating pathology, the EDE-Q was used in the current study to assess for any negative impact on participants. Despite being normative at baseline, the sample’s average global EDE-Q score was found to be significantly lower at follow-up. There are two possible explanations for this outcome. The first is that the intervention had a positive effect on eating pathology. The second is that the result is due to a re-test effect, whereby scores improved (decreased) with each testing occasion, as has been shown to be possible with psychiatric instruments designed to assess negative self-characteristics [77]. Without the presence of a control group to assess whether there is an inherent decrease in scores on the EDE-Q across time, it is not possible to conclude which of the two explanations is the more plausible. In any case, the current findings suggest no evidence that the training had a negative impact on the eating pathology of participants.

Although there was a slight decrease in K10 total scores from baseline to follow-up, this was not statistically significant. This finding is in accordance with previous evaluations of MHFA training and other mental health literacy interventions, and suggests that the training does not have a negative impact on the psychological distress of participants.

Limitations

The absence of a control group is the primary limitation of this research. Without being able to control for extraneous variability in scores over time, concrete conclusions about the role of the training in causing improvements on a number of measures, such as the FAKT and EDE-Q, cannot be reached. However, given that the current research was designed to be a preliminary exploration of how the concept of mental health first aid might be applied to eating disorders, this study has produced some initial evidence to suggest that providing a training intervention to community members increases knowledge and confidence in providing first aid, as well as important data about how future evaluations could be best implemented.

A second limitation of this research is the composition of the sample at baseline. Prior to training, the majority of participants upheld empathic attitudes towards people with bulimia, had relatively good mental health literacy, a large proportion were already in contact with an individual with an eating disorder and had provided some level of assistance. In contrast to the community studies completed by Mond and colleagues, it appears as though the current sample were already functioning above average on a number of variables [e.g. [46, 49, 75, 78]. It was perhaps the nature of the residential college environment, where students live in close contact with one another, members of staff are highly trained in providing pastoral care, and all are well educated, which resulted in participants scoring relatively highly on most measures at baseline. It is also possible that because recruitment materials contained information about both eating disorders and mental health first aid, participants with favourable baseline scores enroled in this study. Research that had a much longer time frame for recruiting participants and could engage interested parties in more subtle ways, may have resulted in a different sample composition.

A third limitation of this research is the size of the sample who reported providing a first aid intervention. Although the proportion of participants who reported providing some form of help (n = 31, 42%) was similar to previous evaluations of MHFA training [e.g. [56], the power to uncover a statistically significant effect is limited by such small numbers. Importantly, the only investigation to examine first aid experiences in a follow-up period longer than six months, found that 78% of respondents had experienced a situation in which they had provided some help, 19 to 21 months after receiving the training [55]. To ensure sufficient statistical power in future research evaluating MHFA training, a combination of a larger number of trained participants and a longer follow-up period should be employed.

Implications of this research

Across most measures of knowledge, significant improvements were found from baseline to post-training. However, these changes were often not maintained at follow-up, as sharp declines occurred in the follow-up period. That the current research was not able to find sustained effects for a number of instruments suggests that the duration or ‘dosing’ effect of the training was inadequate. Given that evaluations of the full MHFA training program, which is presented across four sessions and totals 12 hours, has found much stronger effects at six month follow-up, it would be beneficial for the field of eating disorders for future research to investigate the effect of providing the current training within the full MHFA syllabus. It is also possible that presenting the current training over two or three sessions, with the inclusion of more material focused on the reduction of stigmatising attitudes and modeling of first aid behaviours, would produce lasting significant changes to knowledge, attitudes and behaviours. Such change would no doubt be important in encouraging those with eating disorders to seek appropriate help early, and thereby reduce the current heavy burden associated with these illnesses.
