最近，研究人员开始在心理治疗期间反复测量工作联盟，将工作联盟与逐个疗程的症状变化联系起来。每次会议后回答调查问卷可能会变得乏味，导致粗心的回答和/或丢失数据的水平增加。因此，使用尽可能简单的仪器进行评估是可取的。由于之前对工作联盟量表的研究发现目标和任务因素的分离存在问题，因此本研究在 3 个患者样本（ns = 1,095、235 和 234）中检查了根据工作联盟量表改编的 2 因素、6 项工作联盟测量的心理测量特性。结果显示，双因子模型很好地拟合了 3 个样本的数据，并且因子结构在 10 次初级保健咨询/心理治疗中保持稳定。尽管具有 1 个一般因素和 2 个特定因素的双因素模型在模型拟合方面优于单因素模型，但基于双因素模型结果的维度分析表明，在实践中最好将工具视为一维。结果支持使用所有 6 个项目的综合分数。通过使用自回归潜在轨迹模型重复先前对症状减轻的逐次预测的结果，对该仪器进行了验证。包含 6 项的工作联盟量表（称为“会议联盟清单”）对于研究人员来说是一个很有前途的替代方案，可以在每次会议后寻找简短的联盟措施来管理。
Recently, researchers have started to measure the working alliance repeatedly across sessions of psychotherapy, relating the working alliance to symptom change session by session. Responding to questionnaires after each session can become tedious, leading to careless responses and/or increasing levels of missing data. Therefore, assessment with the briefest possible instrument is desirable. Because previous research on the Working Alliance Inventory has found the separation of the Goal and Task factors problematic, the present study examined the psychometric properties of a 2-factor, 6-item working alliance measure, adapted from the Working Alliance Inventory, in 3 patient samples (ns = 1,095, 235, and 234). Results showed that a bifactor model fit the data well across the 3 samples, and the factor structure was stable across 10 sessions of primary care counseling/psychotherapy. Although the bifactor model with 1 general and 2 specific factors outperformed the 1-factor model in terms of model fit, dimensionality analyses based on the bifactor model results indicated that in practice the instrument is best treated as unidimensional. Results support the use of composite scores of all 6 items. The instrument was validated by replicating previous findings of session-by-session prediction of symptom reduction using the Autoregressive Latent Trajectory model. The 6-item working alliance scale, called the Session Alliance Inventory, is a promising alternative for researchers in search for a brief alliance measure to administer after every session.
