Having meaning in life is a protective factor for psychological well-being. Accurate assessment of this construct needs a valid and reliable tool.
This study aims to evaluate the psychometric properties of the Farsi version of the meaning of life questionnaire in patients with cancer.
In this cross-sectional study, after translating the questionnaire to Farsi, in a sample of 212 patients with cancer, feasibility, content and convergent validity, exploratory and confirmatory factor analysis, internal consistency, stability, and responsiveness were evaluated.
The results show that the content validity ratio of all ten items was greater than 0.49. Also, the modified Kappa coefficient of each item was greater than 0.6. The maximum likelihood exploratory factor analysis extracted one factor, which explains 76.13% of the total variance of the sample. Item nine was removed. The confirmatory factor analysis results show that the one-factor model had good fit indices. The Cronbach's alpha, McDonald's omega, composite reliability, MaxR, and intraclass correlation coefficient were 0.96, 0.96, 0.96, 0.96, and 0.98, respectively. The questionnaires had responsiveness and its response time was 3 s.
The nine-item Farsi version of the meaning of life questionnaire has good validity and reliability and responsiveness.

本研究旨在评估癌症患者中文版生活意义问卷的心理测量特性。
在这项横断面研究中，我们将问卷翻译成波斯语，对 212 名癌症患者进行了可行性、内容和收敛效度、探索性和验证性因素分析、内部一致性、稳定性和反应度评估。
结果表明，所有 10 个条目的内容效度比均大于 0.49。此外，每个项目的修正 Kappa 系数均大于 0.6。最大似然探索性因素分析提取出一个因子，解释了样本总方差的 76.13%。删除了第 9 项。验证性因素分析结果表明，单因素模型具有良好的拟合指数。克朗巴赫 α、麦克唐纳 ω、综合可靠性、最大 R 和组内相关系数分别为 0.96、0.96、0.96、0.96 和 0.98。问卷具有反应性，其反应时间为 3 秒。
九项中文版生活意义问卷具有良好的有效性、可靠性和反应性。
