Suicidal thoughts are relatively common among college students in Iran. However, measures frequently used to assess suicidality or specific aspects of suicidal ideation in the United States have yet to be validated in Iran. Thus, the present study validated Farsi versions of the Depressive Symptom Inventory Suicidality Subscale (F-DSI-SS) and Suicide Rumination Scale (F-SRS) among Iranian college students.
College students (N = 1043; 88.1% women) completed the F-DSI-SS. Forty-six percent (n = 481) of participants reported the presence of suicidal thoughts and were eligible to fill out the F-SRS. Analyses focused on validating the factor structure, construct, and convergent validity of the F-DSI-SS and F-SRS among college students, as well as testing measurement invariance by gender of the F-DSI-SS.
Confirmatory factor analysis (CFA) indicated that the F-DSI-SS and F-SRS had good fit to the data and each displayed a one-factor structure. Furthermore, the F-DSI-SS showed strong measurement invariance across genders. Internal consistency of the F-DSI-SS and F-SRS was good. Lastly, the F-DSI-SS and F-SRS's items and their total scores were intercorrelated and demonstrated good convergent validity.
Findings suggest that the F-DSI-SS and F-SRS will enable researchers to examine suicidal thoughts and suicide-specific rumination in Iran.
自杀念头在伊朗大学生中相对普遍。然而,美国常用的评估自杀倾向或自杀意念特定方面的方法在伊朗尚未得到验证。因此,本研究在伊朗大学生中验证了抑郁症状量表自杀倾向分量表(F-DSI-SS)和自杀沉思量表(F-SRS)的波斯语版本。
大学生(N = 1043;88.1%为女性)完成了F-DSI-SS。46%(n = 481)的参与者报告有自杀念头,并有资格填写F-SRS。分析重点在于验证F-DSI-SS和F-SRS在大学生中的因子结构、构想效度和收敛效度,以及检验F-DSI-SS在性别上的测量不变性。
验证性因子分析(CFA)表明,F-DSI-SS和F-SRS与数据拟合良好,且均呈现单因子结构。此外,F-DSI-SS在不同性别间显示出很强的测量不变性。F-DSI-SS和F-SRS的内部一致性良好。最后,F-DSI-SS和F-SRS的项目及其总分相互关联,显示出良好的收敛效度。
研究结果表明,F-DSI-SS和F-SRS将使研究人员能够在伊朗研究自杀念头和特定于自杀的沉思。
