BACKGROUND
Due to the growing prevalence of suicide, assessing people's attitudes toward suicide is necessary. Therefore, this study aimed to examine the psychometric properties of the Persian version of the Predicaments Questionnaire (PQ), measuring social attitudes toward suicide.
METHODS
This psychometrics study evaluated face validity, content validity, temporal stability, internal consistency, and construct validity. First, the questionnaire was translated into Persian by the translate-back-translate method. The Persian version was provided to 10 experts in psychiatry for further revision. Two indicators, CVR and CVI, were calculated to evaluate the content validity. To check the face validity, we prepared a form and gave it to 10 people outside the campus to submit their opinions. Temporal stability was investigated by the test-retest method, reporting Intraclass correlation (ICC). Internal consistency was assessed by reporting Cronbach's alpha and McDonald's Omega coefficients. Construct validity was assessed using the confirmatory factor analysis to determine the number of dimensions of the questionnaire.
RESULTS
A total of 151 students were enrolled with a mean age of 25 (SD = 0.32). The Persian PQ was valid in terms of content validity and face validity. Furthermore, it was reliable as Cronbach's alpha, McDonald's Omega, and the ICC were 0.94, 0.943, and 0.998, respectively. In addition, the confirmatory factor analysis yielded one dimension. Finally, after reviewing the experts' comments, the final amendments were made, and only question 29 was removed from the final version.
CONCLUSION
Consequently, the Persian version of the PQ is acceptable in terms of content validity, face validity, temporal stability, and internal consistency.
背景
由于自杀的发生率不断上升，评估人们对自杀的态度是必要的。因此，本研究旨在检验用于测量社会对自杀态度的困境问卷（PQ）的波斯语版本的心理测量学特性。
方法
本心理测量学研究评估了表面效度、内容效度、时间稳定性、内部一致性和构念效度。首先，通过翻译回译的方法将问卷翻译成波斯语。将波斯语版本提供给 10 名精神病学专家进行进一步修订。计算内容效度的两个指标，内容效度值（CVR）和内容效度指数（CVI）。为了检查表面效度，我们准备了一份表格，让校园外的 10 人提交他们的意见。采用测试-重测法评估时间稳定性，报告组内相关系数（ICC）。通过报告 Cronbach's alpha 和 McDonald's Omega 系数评估内部一致性。使用验证性因子分析评估结构效度，以确定问卷的维度数。
结果
共纳入 151 名学生，平均年龄为 25 岁（SD = 0.32）。波斯语 PQ 在内容效度和表面效度方面是有效的。此外，它是可靠的，因为 Cronbach's alpha、McDonald's Omega 和 ICC 分别为 0.94、0.943 和 0.998。此外，验证性因子分析得出一个维度。最后，在审查专家的意见后，进行了最终修订，仅从最终版本中删除了第 29 个问题。
结论
因此，PQ 的波斯语版本在内容效度、表面效度、时间稳定性和内部一致性方面是可以接受的。
