  1. aIn the three logistic regression analyses, responses to the three variables about suicide knowledge were dichotomized: ‘definitely disagree’ , ‘mostly disagree’ and ‘neither agree nor disagree’ were coded as ‘1’; ‘mostly agree’ and ‘definitely agree’ were coded as ‘2’. Two variables were initially forced into the models (gender, and years of working as a psychiatrist) and then eleven other variables (type of hospital [tertiary psychiatric center v. district hospital or rehabilitation center], professional status [entered as two dummy variables using attending psychiatrist as the reference group], years of education, whether or not the clinician’s current work was limited to inpatient service provision and the seven subscales scores of the SPAS) were entered by a forward stepwise method if significant at the p < 0.05 level.
