Abstract

Objective: The study aimed to test the psychometric properties of the Czech translation of the Questionnaire of Personal Changes (Q-PC), a measure designed for retrospective (direct) measurement of change in psychotherapy.

Methods: A sample of group psychotherapy clients (N = 222) and a nonclinical sample (N = 167) sample were used. Clients in the clinical sample were administered the Q-PC in addition to several pre-post outcome measures. Confirmatory factor analysis, correlational analysis, and structural equation modeling were used to test the Q-PC's factor structure, longitudinal measurement invariance, reliability, convergent validity, sensitivity to change, and other psychometric properties.

Results: The Q-PC demonstrated a unidimensional structure that was strictly invariant between two follow-up measurement waves. The measure also demonstrated excellent reliability and sensitivity to change and good convergent validity. Furthermore, it demonstrated a similar relationship to baseline severity as the pre-post outcome measures.

Conclusions: The retrospective measurement of change is a promising approach that has the potential to complement the traditional pre-post measurement of change.

直接回顾性测量治疗变化：以捷克版个人变化问卷（Q-PC）为例。

研究目的该研究旨在测试个人变化问卷（Q-PC）捷克语译文的心理测量特性：方法：采用团体心理治疗客户样本（N = 222）和非临床样本（N = 167）。临床样本中的受试者除了接受Q-PC测试外，还接受了几项前后结果测量。我们使用了确认性因子分析、相关分析和结构方程模型来测试 Q-PC 的因子结构、纵向测量不变性、可靠性、收敛有效性、对变化的敏感性以及其他心理测量特性：结果：Q-PC显示了一个单维结构，在两个随访测量波之间具有严格的不变性。该测量结果还显示出极佳的可靠性和对变化的敏感性，以及良好的收敛效度。此外，它与基线严重程度之间的关系与前后结果测量相似：结论：对变化进行回顾性测量是一种很有前途的方法，有可能对传统的事后前变化测量进行补充。
