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

摘要：
■该研究旨在测试个人变化问卷（Q-PC）的捷克语翻译的心理测量特性，一种用于回顾性（直接）测量心理治疗变化的方法。
■使用一组心理治疗对象样本（N=222）和非临床样本（N=167）样本。除了几个前-后结果测量外,对临床样品中的客户施用Q-PC。验证性因素分析，相关分析，并采用结构方程模型对Q-PC的因子结构进行了检验，纵向测量不变性，可靠性,收敛有效性，对变化的敏感性,和其他心理测量属性。
■Q-PC展示了在两个后续测量波之间严格不变的一维结构。该措施还表现出优异的可靠性和对变化的敏感性以及良好的收敛有效性。此外，它显示与基线严重程度的关系与pre-post结局指标相似.
■对变化进行回顾性测量是一种有前途的方法，有可能补充传统的变化前的后测量。
