Abstract
BACKGROUND AND AIM: The loss of a loved one through death is practically an inevitable part of the human experience. However, not all grieving people cope with this blow in the same way. One of the factors that may differentiate the grieving reactions of mourners in the face of this lesion is the strategies that the person uses in this situation to adapt and manage the situation. A valid and reliable tool is also needed to measure and evaluate coping strategies. The aim of this study was to translate and determine the characteristics of psychological tools for measuring coping with experiences of grief and loss (28 items) in people living in Tehran. MATERIALS AND METHODS: This is a methodological study with a descriptive cross-sectional design that after obtaining written permission from the original developer and according to the WHO protocol, the Persian version of the questionnaire was completed by 480 people who experienced mourn in Tehran in February 2021 to October 2021. Then, the Face validity, Content validity and Construct validity of questionnaire were assessed. Cronbach's alpha coefficient, McDonald's omega and Test-retest were used to determine the reliability. RESULTS: Cronbach's alpha for all items was 0.91 and intra-class correlation coefficient was 0.86, both of which indicate the reliability of the Persian version of the CABLE tool. Based on exploratory factor analysis, maximum likelihood (n = 260) and confirmatory factor analysis (n = 220) six factors were identified. Factors can explain 50% of the total variance observed. The model had an acceptable fit: GFI: 0.88, CFI: 0.96, IFI: 0.96, NFI: 0.92, PNFI: 0.82, RAMSEA: 0.058, CMIN / DF: 2.37 RMR: 0.056. Internal consistency and construct validity of the questionnaire were confirmed. CONCLUSION: The findings of the present study indicate that the Persian version of CABLE has the appropriate validity and reliability to assess the compliance with the experiences of grief and loss in Persian population.
