Measuring sexual relationship power in HIV/STD research

This article introduces a theoretically based and validated measure of relationship power dynamics: the Sexual Relationship Power Scale (SRPS). Focus groups were conducted to generate items for Spanish- and English-language scales. The SRPS was administered to a census of women (N = 388) at a community health clinic. All respondents had a primary male partner; they were mostly Latina (89%), with mean age 27 years. The 23-item SRPS possesses good internal reliability (coefficient alpha = .84 for English version, .88 for Spanish version) and predictive and construct validity, Factor analyses support two subscales: Relationship Control and Decision-Making Dominance. As hypothesized, the SRPS was inversely associated with physical violence and directly associated with education and consistent condom use (P < .05).
