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. Practitioner points SCORE‐15 is a systemic self‐report measure reliable for routine clinical use with LGB people and couples in the UK to measure relational changes. The use of the term family affects the content validity of SCORE‐15 for LGB people and couples who may not regard family as their primary relationships. R‐SCORE‐15 is a recommended alternative to SCORE‐15 for couples, LGB people and those who may not define significant relationships via biology or marital ties. 从家庭到关系版SCORE‐15：为伴侣和LGB群体另行设计的成人版系统自我报告量表 SCORE‐15是为系统性治疗方法设计的一份自我报告量表。 本文描述了一项初步研究, 其目的在于测试原版SCORE‐15在英国女同性恋、男同性恋和双性恋（LGB）群体中的信度和内容效度。对一个LGB群体样本（n = 59）和一个非LGB群体样本（n = 57）的数据进行定量分析的结果显示, 除了其中的沟通分量表之外, SCORE‐15具有足够的跨时间信度和内部一致性信度。对SCORE‐15的内容效度的检测是通过与两个专业临床人士小组（n = 57）和一个同性/双性恋男性小组（n = 58）的小组讨论来进行的。在此基础上, 新设计了另一份成人版SCORE‐15, 将其命名为关系版SCORE‐15或者R‐SCORE‐15。在原有的专业临床人士上, 新加了一个专业人士组（n = 8）, 以确定这一新量表的内容效度。R‐SCORE‐15具有足够的内容效度以供关系治疗中的伴侣和LGB人群的临床使用。 对实务工作者的启示 SCORE‐15是一种系统性的自我报告量表, 在测试英国LGB群体和伴侣关系变化的临床用途上具有信度。 对于LGB群体和伴侣来说, “家庭” 这个词的使用影响了SCORE‐15的内容效度, 因为他们可能并不把家庭看作他们的首要关系。 对于伴侣、LGB群体和不将血缘或婚姻关系当作重要关系的人群, 推荐使用R‐SCORE‐15作为代替。 关键词：LGB；女同性恋；男同性恋和双性恋；SCORE‐15；关系版SCORE‐15；R‐SCORE‐15；常规测量指标；系统性自我报告量表；信度和效度；伴侣治疗；LGB适用的SCORE‐15
