Measurement limitations lessen the conclusions about the role of the alliance in youth psychosocial treatment. This article examined the score reliability, factor structure, and validity of the 9-item Therapy Process Observational Coding System for Child Psychotherapy-Alliance scale (TPOCS-A). The sample, 51 youth aged 7-15 years (Mage = 10.36 years, SD = 1.90; 86.3% White; 60.8% male, 39.2% female), met diagnostic criteria for a principal anxiety disorder and received cognitive-behavioral therapy. Treatment sessions (N = 463) were coded by independent coders using the TPOCS-A along with observational measures of treatment adherence and therapist competence. Youth and therapists also completed self-report alliance measures at the end of each session. Reliability estimates, ICC(2,2), at the item level indicated a mean interrater reliability of .68 (SD = .10) and a mean coder stability of .64 (SD = .11). An exploratory factor analysis identified a one-factor solution with five items. TPOCS-A scores evidenced convergent validity with the therapist and adolescent reports of alliance but did not converge with the child-report alliance measure. TPOCS-A scores evidenced discriminant validity when compared with scores on adherence and competence measures. The reliability and validity profile of the 9- and 5-item versions of the TPOCS-A were similar. Overall, findings support the reliability and validity of the TPOCS-A scores, but questions remain about how best to assess the alliance with children.

观察者评级的青年联盟量表的可靠性、因素结构和有效性。


测量的局限性削弱了关于联盟在青少年心理社会治疗中的作用的结论。本文检验了儿童心理治疗联盟量表的 9 项治疗过程观察编码系统 (TPOCS-A) 的评分可靠性、因子结构和有效性。样本包括 51 名 7-15 岁青少年（Mage = 10.36 岁，SD = 1.90；86.3% 白人；60.8% 男性，39.2% 女性），符合主要焦虑症的诊断标准，并接受了认知行为治疗。治疗疗程 (N = 463) 由独立编码员使用 TPOCS-A 以及治疗依从性和治疗师能力的观察措施进行编码。青少年和治疗师还在每次治疗结束时完成自我报告联盟措施。项目级别的可靠性估计 ICC(2,2) 表明平均人际可靠性为 0.68 (SD = .10)，平均编码器稳定性为 0.64 (SD = .11)。探索性因素分析确定了包含五个项目的单因素解决方案。 TPOCS-A 分数证明了与治疗师和青少年联盟报告的收敛有效性，但与儿童报告联盟测量并不收敛。与依从性和能力测量的分数相比，TPOCS-A 分数证明了区分有效性。 TPOCS-A 的 9 项和 5 项版本的信度和效度特征相似。总体而言，研究结果支持 TPOCS-A 分数的可靠性和有效性，但如何最好地评估与儿童的联盟仍然存在问题。 （PsycInfo 数据库记录 (c) 2021 APA，保留所有权利）。
