The PG-13-Revised (PG-13-R) is a self-report measure to assess prolonged grief disorder (PGD) in terms of Diagnostic and Statistical Manual of Mental Disorders, fifth revision, Text Revision. This measure has been shown to yield good psychometric properties in Western samples. This study aimed to evaluate the psychometric properties of the Persian PG-13-R.
Three hundred forty-seven individuals (209 women and 138 men) fully completed the scales. The participants were recruited using convenience sampling. The confirmatory factor analysis (CFA), convergent and divergent validity, and reliability of the Persian version of the PG-13-R were evaluated.
CFA results of a unidimensional model support the construct validity of this version of the PG-13-R. The results of this study demonstrated that this version of the PG-13-R has internal consistency reliability (omega coefficient of 0.93), and the test-retest reliability with an interval of 6 weeks was 0.89. The convergent and divergent validity was shown with significant correlations between the PG-13-R and measures of depression, PTSD, functional impairment, and hope.
Overall, the Persian version of the PG-13-R showed good psychometric properties in the Iranian population.
PG-13-Revised（PG-13-R）是一种自我报告的测量工具，用于评估《精神障碍诊断与统计手册》第五版修订本（DSM-5-R）中的延长哀伤障碍（PGD）。该测量工具在西方样本中表现出良好的心理测量特性。本研究旨在评估 PG-13-R 的波斯语版本的心理测量特性。
347 名个体（209 名女性和 138 名男性）完整地完成了量表。参与者是通过方便抽样招募的。评估了波斯语 PG-13-R 的验证性因素分析（CFA）、收敛和发散效度以及信度。
单维模型的 CFA 结果支持该版本 PG-13-R 的结构效度。本研究结果表明，该版本的 PG-13-R 具有内部一致性信度（omega 系数为 0.93），6 周间隔的重测信度为 0.89。PG-13-R 与抑郁、创伤后应激障碍、功能障碍和希望的测量之间存在显著相关性，表明了其收敛和发散效度。
总体而言，PG-13-R 的波斯语版本在伊朗人群中表现出良好的心理测量特性。
