The perceived ethnic discrimination questionnaire--community version: validation in a multiethnic Asian sample.

This study evaluated the validity and reliability of the Perceived Ethnic Discrimination Questionnaire-Community Version (PEDQ-CV) Lifetime Exposure scale in a multiethnic Asian sample (N = 509). The 34-item scale measures perceived interpersonal racial/ethnic discrimination and includes four subscales assessing different types of discrimination: Social Exclusion, Stigmatization, Discrimination at Work/School, and Threat/Aggression. The Lifetime Exposure scale demonstrated excellent reliability across the full group and in all major subgroups. Subscales displayed good reliability across the full group and moderate-to-good reliability in each subgroup. The Lifetime Exposure scale was significantly correlated with the depression and anxiety subscales of the SCL-90-R, providing preliminary evidence of construct validity. The data suggest the Lifetime Exposure scale, previously validated in Black and Latino adults, is also appropriate for use with Asian samples, and can be used to examine both within-group and between-groups differences in discrimination.

Dimensions of perceived racism and self-reported health: examination of racial/ethnic differences and potential mediators.

BACKGROUND: Many details of the negative relationship between perceived racial/ethnic discrimination and health are poorly understood. PURPOSE: The purpose of this study was to examine racial/ethnic differences in the relationship between perceived discrimination and self-reported health, identify dimensions of discrimination that drive this relationship, and explore psychological mediators. METHODS: Asian, Black, and Latino(a) adults (N=734) completed measures of perceived racial/ethnic discrimination, self-reported health, depression, anxiety, and cynical hostility. RESULTS: The association between perceived discrimination and poor self-reported health was significant and did not differ across racial/ethnic subgroups. Race-related social exclusion and threat/harassment uniquely contributed to poor health for all groups. Depression, anxiety, and cynical hostility fully mediated the effect of social exclusion on health, but did not fully explain the effect of threat. CONCLUSIONS: Our results suggest that noxious effects of race-related exclusion and threat transcend between-group differences in discriminatory experiences. The effects of race-related exclusion and threat on health, however, may operate through different mechanisms.
