Abstract: (5 Views)
The present study aimed to examine the psychometric properties of the Persian version of the Prejudice toward People with Mental Illness Scale among Iranian adults. The study employed a cross-sectional psychometric design. The statistical population comprised all adults residing in Tabriz, Iran, in 2025, from whom a sample of 392 participants was recruited using convenience sampling. The research instruments included the Prejudice toward People with Mental Illness Scale (PPMI; Kenny et al., 2018), the Reported and Intended Behaviour Scale (RIBS; Evans-Lacko et al., 2011), the Social Dominance Orientation Scale (SDOS; Pratto et al., 2013), and the Social Distance Scale (SDS; Link et al., 2004). Data were analyzed using confirmatory factor analysis, internal consistency, and Pearson correlation coefficient. The results of confirmatory factor analysis indicated that after removing three items, the four-factor structure of the scale demonstrated good fit. The instrument showed positive correlations with mental illness stigma, social distance, and social dominance orientation, supporting the divergent and concurrent validity of the scale (p <.01). Reliability was assessed using Cronbach’s alpha, McDonald's omega, and composite reliability coefficients, both of which exceeded .70, indicating satisfactory reliability. Overall, the Persian version of the Prejudice toward People with Mental Illness Scale demonstrated adequate psychometric properties and can be used in future research and clinical settings.
