Measuring stigma in people with HIV: Psychometric assessment of the HIV stigma scale

An instrument to measure the stigma perceived by people with HIV was developed based on the literature on stigma and psychosocial aspects of having HIV. Items surviving two rounds of content review were assembled in a booklet and distributed through HIV‐related organizations across the United States. Psychometric analysis was performed on 318 questionnaires returned by people with HIV (19% women, 21% African American, 8% Hispanic). Four factors emerged from exploratory factor analysis: personalized stigma, disclosure concerns, negative self‐image, and concern with public attitudes toward people with HIV. Extraction of one higher‐order factor provided evidence of a single overall construct. Construct validity also was supported by relationships with related constructs: self‐esteem, depression, social support, and social conflict. Coefficient alphas between .90 and .93 for the subscales and .96 for the 40‐item instrument provided evidence of internal consistency reliability. The HIV Stigma Scale was reliable and valid with a large, diverse sample of people with HIV. © 2001 John Wiley & Sons, Inc. Res Nurs Health 24:518–529, 2001
