This paper describes 2 studies that evaluated a new instrument, the Perceived Ethnic Discrimination Questionnaire-Community Version (PEDQ-CV). The PEDQ-CV can be used across ethnic groups to assess perceived racism or ethnic discrimination. The scales measure several subdimensions of racism, permitting the examination of different forms of this race-related stressor. The first study evaluated the psychometric properties of the PEDQ-CV in a large sample of community-dwelling adults. The second evaluated psychometric properties of a brief version of the PEDQ-CV, developed for research protocols requiring a shorter administration time. Tests were made of reliability and several forms of construct validity. Both versions of the PEDQ-CV have good reliability and construct validity. The PEDQ-CV can facilitate the development of an integrative body of knowledge across different ethnic groups regarding the existence, determinants, and consequences of discrimination.Racism or ethnic discrimination3 has been hypothesized to contribute to the well-documented racial and ethnic disparities in health (Anderson & Armstead, 3There is little consensus on the best terms to use to distinguish among groups based on phenotypic or cultural characteristics, and both scientific and political factors influence the debate. Some terms (e.g., Black) have been used to refer to racial groups, Vootnote continues on the nexr puge)

Ethnic discrimination experienced in an interpersonal context has been identified as a stressor contributing to racial disparities in health. Exposure to racism may influence the way people view their ongoing experiences, making it more likely that individuals will appraise new situations as threatening and harmful, adding to their overall stress burden. A multiethnic sample of 113 adults completed a diary page every 30 min for one day. The diary inquired about moods and perceptions of social interactions. When controlling for personality characteristics, mixed models regression analyses indicated that baseline measures of ethnic discrimination (assessed with the Perceived Ethnic Discrimination Scale-Community Version) were positively associated with daily levels of anger and the intensity of participants' rating of routine social interactions as harassing, exclusionary, and unfair. These findings have implications for models of the contribution of psychosocial factors to racial disparities in health.
