Development and Validity of the Personal Suicide Stigma Questionnaire (PSSQ).

Background: The detrimental consequences of stigma have been recognized in extensive research on mental illness stigma, but experiences of suicide-related stigmatization have not received sufficient research attention. The lack of a simple self-report assessment of personal suicide-related stigma led to the work reported here. Aim: To develop and assess the validity of the Personal Suicide Stigma Questionnaire (PSSQ). Method: The item pool for PSSQ was based on qualitative data and was tested in a community sample of 224 adults (mean age = 32.68 years, 83% female, 92.9% Caucasian) who reported lifetime suicidality. Factor analysis was used for item selection. The Self-Stigma of Mental Illness Scale - Short form (SSMIS-SF) and Suicide Behaviors Questionnaire - Revised (SBQ-R) were used to assess validity of the scale. Results: Following analysis, 16 items, forming three highly interrelated factors (Rejection, Minimization, and Self-blame), were selected for the PSSQ. The PSSQ scores showed predicted relationships with mental illness stigma and suicidality, suggesting its validity. Limitations: The validity of the scale still requires further research in clinical populations. Conclusion: The newly developed PSSQ can be used to assess the levels of suicide-related stigma experiences of suicidal individuals.
