This study aimed to evaluate the psychometric properties of the Persian version of the International ICD-11 Prolonged Grief Disorder Scale (IPGDS).
A total of 554 participants (18 years and older, 326 women) completed the Persian IPGDS along with other measures. Participants were recruited through convenience sampling. The study assessed confirmatory factor analysis (CFA), convergent validity, and reliability of the Persian IPGDS.
CFA supported a 4-dimensional model, indicating good structural validity of the Persian IPGDS. Convergent validity was established through correlations with measures of depression, anxiety, and PTSD.
These findings suggest that the Persian IPGDS exhibits satisfactory psychometric properties, making it a valid tool for measuring Prolonged Grief Disorder (PGD) in Persian-speaking Iranian adults.
本研究旨在评估国际疾病分类第11版（ICD - 11）持续性悲伤障碍量表（IPGDS）波斯语版本的心理测量特性。
共有554名参与者（年龄18岁及以上，326名女性）完成了波斯语IPGDS以及其他测量。参与者通过便利抽样招募。该研究评估了波斯语IPGDS的验证性因素分析（CFA）、收敛效度和信度。
CFA支持一个4维模型，表明波斯语IPGDS具有良好的结构效度。通过与抑郁、焦虑和创伤后应激障碍测量指标的相关性建立了收敛效度。
这些发现表明，波斯语IPGDS具有令人满意的心理测量特性，使其成为测量说波斯语的伊朗成年人持续性悲伤障碍（PGD）的有效工具。
