หัวข้อ Experiences of discrimination: Validityand reliabilityof a self-report measure for population health research on racism and health
บทนำ: Population health research on racial discrimination is hampered bya paucity of psychometrically validated
instruments that can be feasiblyused in large-scale studies. We therefore sought to investigate the validityand reliability
of a short self-report instrument, the ‘‘Experiences of Discrimination’’ (EOD) measure, based on a prior instrument
used in the CoronaryArtery Risk Development in Young Adults (CARDIA) study.
Studypar ticipants were drawn from a cohort of working class adults, age 25–64, based in the Greater Boston area,
Massachusetts (USA). The main studya nalytic sample included 159 black, 249 Latino, and 208 white participants; the
validation studyin cluded 98 African American and 110 Latino participants who completed a re-test survey two to four
weeks after the initial survey. The main and validation survey instruments included the EOD and several single-item
discrimination questions; the validation surveyal so included theWilliamsMajor and Everyday discrimination measures.
Keyfindings indicated the EOD can be validlyand reliablyemploy ed. Scale reliabilitywas high, as demonstrated by
confirmatoryfactor analysis, Cronbach’s alpha (0.74 or greater), and test–re-test reliabilitycoefficients (0.70).
Structural equation modeling demonstrated the EOD had the highest correlation (r ¼ 0:79) with an underlying
discrimination construct compared to other self-report discrimination measures employed. It was significantly
associated with psychological distress and tended to be associated with cigarette smoking among blacks and Latinos,
and it was not associated with social desirabilityin either group. Bycontrast, single-item measures were notablyless
reliable and had low correlations with the multi-item measures. These results underscore the need for using validated,
multi-item measures of experiences of racial discrimination and suggest the EOD maybe one such measure that can be
validlyemploy ed with working class African Americans and Latino Americans.
