The aim of the present study was 2-fold: (a) to examine the factor structure of the short version of the Working Alliance Inventory (WAI-S) in clients who were engaged in individual career counseling sessions and (b) to investigate whether the factor structure of the WAI-S is invariant across the first and the third career counseling sessions. A total of 283 clients seeking individual career counseling completed the WAI-S at the end of the first session (T1). Of the 283 clients, 217 also completed the WAI-S at the end of the third session (T2). Confirmatory factor analyses were performed to assess the fit of one-factor, two-factor, three-factor, and bilevel hierarchical models. The results showed that the three-factor and the bilevel hierarchical models had the best fit to the data at both T1 and T2. The factor structure of the WAI-S was invariant across the first and the third career counseling sessions. Results suggest that researchers and clinicians can use the WAI-S knowing that it adequately measures Bordin’s theoretical model of working alliance in the specific context of individual career counseling.

短期工作咨询清单的因素结构及其在各个职业咨询会议中的纵向测量不变性

本研究的目的是双重的：（a）在参加个人职业咨询课程的客户中，检查短版工作联盟清单（WAI-S）的因素结构，以及（b）调查是否在第一和第三次职业咨询中，WAI-S的因素结构是不变的。在第一届会议（T1）结束时，共有283位寻求个人职业咨询的客户完成了WAI-S。在283个客户中，有217个在第三届会议（T2）结束时也完成了WAI-S。进行验证性因素分析以评估一因素，两因素，三因素和双层层次模型的拟合度。结果表明，三因素和双层层次模型最适合T1和T2的数据。在第一和第三次职业咨询中，WAI-S的因素结构是不变的。结果表明，研究人员和临床医生可以使用WAI-S，因为它可以在个人职业咨询的特定情况下充分衡量Bordin的工作联盟理论模型。
