Abstract

This study examined the assumption of measurement invariance of the SAMSHA Mental Health and Alcohol Abuse Stigma Assessment. This is necessary to make valid comparisons across time and groups. The data come from the Primary Care Research in Substance Abuse and Mental Health for Elderly trial, a longitudinal multisite, randomized trial examining two modes of care (Referral and Integrated). A sample of 1,198 adults over the age of 65 who screened positive for depression, anxiety, and/or at-risk drinking was used. Structural equation modeling was used to assess measurement invariance in a two-factor measurement model (Perceived Stigma, Comfort Level). Irrespective of their stigma level, one bias indicated that with time, respondents find it easier to acknowledge that it is difficult to start treatment if others know they are in treatment. Other biases indicated that sex, mental quality of life and the subject of stigma had undue influence on respondents’ feeling people would think differently of them if they received treatment and on respondents’ comfort in talking to a mental health provider. Still, in the present study, these biases in response behavior had little effect on the evaluation of group differences and changes in stigma. Stigma decreased for patients of both the Referral and Integrated care groups.
