From family to relational SCORE-15: an alternative adult version of a systemic self-report measure for couples and LGB People

SCORE-15 is a self-report measure developed for systemic approaches to therapy. This article describes a pilot study designed to test the reliability and content validity of the original SCORE-15 for lesbian, gay and bisexual (LGB) adults in the UK. Quantitative data analyses conducted with an LGB sample (n=59) and a non-LGB sample (n=57) found sufficient temporal and internal reliability in the SCORE-15 but with some exceptions for the communication subscale. The content validity of SCORE-15 was checked via group discussions with two clinical professionals groups (n=7) and a gay/bisexual men group (n=8). An alternative adult version of SCORE-15 named the relational SCORE-15 or the R-SCORE-15 was constructed and its content validity was checked by the original clinical professionals and an additional professional group (n=8). The R-SCORE-15 has content validity for clinical use with couples and LGB people in relationship therapy.
