N2 - Background: The 8-item self-report Perceived Stigma toward Substance Users Scale (PSAS) is a commonly used instrument to assess stigma for people with substance use disorders. This study aimed to develop and validate the Taiwan version of the PSAS entitled Perceived Stigma toward People who use Substances – Taiwan version (PSPS-TV) among individuals with substance use disorders. Methods: Patients with substance use disorders (N = 300; mean age = 45.22; 255 males) completed the PSPS-TV, Self-Stigma Scale-Short (SSS-S), Taiwan Depression Questionnaire (TDQ), and Rosenberg Self-Esteem Scale (RSES). Confirmatory factor analysis was used to test the construct validity and the measurement invariance of the PSPS-TV. Concurrent validity was tested using the correlations between PSPS-TV and SSS-S, TDQ, and RSES scores. Results: The confirmatory factor analysis supported the construct validity and measurement invariance of the PSPS-TV. SSS-S scores explained 13 %, TDQ scores explained 10 % and RSES scores explained 17 % of the PSPS-TV score variance with moderate standardized coefficients (0.38, 0.32 and −0.42, respectively; all p < 0.001). Conclusions: The PSPS-TV is an appropriate instrument to assess perceived stigma for individuals residing in Taiwan who have substance use disorders. Taiwan healthcare providers may thus consider using the PSPS-TV to assess perceived stigma relating to substance use in Taiwan.
