Permission to translate the instruments was obtained from the original authors. The instruments were first translated into Swedish and then retranslated into English. The language in the different versions were compared and adjusted to the final Swedish versions.
The self-report inventory of fear of and behavioural intentions toward the mentally ill (FABI) is a ten item questionnaire with a five point response scale for each question. Responses are coded from 1 to 5 and the items include:
Fear: (response alternatives: strongly agree, agree, neutral, disagree and strongly disagree)
"I am afraid of people with mental illness"
Behavioural intentions: (response alternatives: very likely, likely, uncertain, unlikely, very unlikely)
"Would you object to having mentally ill people living in your neighbourhood?"
"Would you avoid conversations with neighbours who had suffered from mental illness?"
"Would you be willing to work with somebody with a mental illness?"
"Would you invite somebody into your home if you knew they suffered from mental illness?"
"Would you be worried about visiting somebody with a mental illness?"
"If somebody had been a former psychiatric patient, would you have them as a friend?"
"If somebody who had been a former psychiatric patient came to live next door to you, would you greet them occasionally?"
"Would you have casual conversations with neighbours who had suffered from mental illness?"
"If somebody who had been a former psychiatric patient came to live next door to you, would you visit them?" [28, 29]
Changing Minds: Every family in the Land
The instrument was, in the original study, administered as an interview and two sets of data were obtained . The first set collected data about household composition and individual demographic and employment-related circumstances. This set was not used in the present study. The second set was designed to obtain perceptions about seven mental disorders, identified in pre-interview focus groups and then targeted by the Royal College of Psychiatrists campaign. The focus groups had indicated that these disorders were familiar to the general public. The disorders were severe depression, panic attacks, schizophrenia, dementia, eating disorders, alcoholism and drug addiction. The questions about the disorders were based on findings presented in a literature review on stigmatization of people with mental disorders by Hayward and Bright . The key perceptions of persons with mental illness are that they are dangerous, unpredictable, are difficult to talk with, have only themselves to blame, are able to pull themselves together, have a poor outcome and don't respond very much to treatment according to this review. For each disorder the respondents could rank their perception on a five point scale from one extreme e.g. "dangerous to others", to the opposite, "not dangerous to others", "unpredictable" to "not unpredictable" and so forth. In the present study the questions were administered as a self-rating questionnaire.

Sample and Data collection
The sample consisted of 51 students in a three year educational programme in nursing. They were in their second semester and during the data collection period they were studying physiology and anatomy. Nothing in their present education had, to our knowledge, a content that could affect their view of mental disorders. The first data collection was made in September, 2007 and the retest data collection was made three weeks later. No major media discussions concerning mental illness occurred during the time period between the test and retest data collection. Being as this investigation is a part of a larger study concerning the impact of formal education in psychiatry on attitudes towards mental illness baseline data from a larger database was used to examine internal consistency. This larger database consisted of 1001 students from educational programmes including psychiatry in their curriculum. The following student categories were represented: nursing, medicine, social work, physiotherapy, occupational therapy, psychology, public health work, and police trainee.
Weighted kappa coefficients were calculated for each item in the two questionnaires in order to investigate the test - retest reliability for the different instruments. The reference values for the strength of agreement are from Altman  who considers < 0.20 as poor agreement, 0.21-0.40 as fair, 0.41-0.60 as moderate, 0.61-0.80 as good and 0.81-1.00 as a very good agreement. Weighted kappa is used because it takes into account the magnitude of the discrepancy in ordinal data. A weakness of ordinary kappa statistics is that it treats all disagreements equally whether they are very large or very small . Internal consistency was examined by calculating Cronbach's alpha coefficient for the FABI. In the questionnaire from the Changing Minds campaign the Cronbach's alpha coefficient was calculated for the responses concerning each disorder. The statistical software used was SPSS 15.0 and Vasserstats .
