Validation Of The Malay Version Of The Posttraumatic Growth Inventoryshort Form (Ptgi-Sf) Among Malaysian Cancer Patients

ABSTRACT

Introduction: Posttraumatic growth (PTG) is a positive psychological change in life that occurs as a result of struggle with highly challenging life crises. There is a growing need to explore posttraumatic growth (PTG) in cancer patients, as higher PTG may enhance well-being of patients. Objectives: The aim of this study was to translate the Posttraumatic Growth Inventory-Short Form (PTGISF) into the Malay language and evaluate its psychometric properties for assessing Malaysian cancer patients in future studies. Methods: Two parallels forward and backward translations of the PTGI-SF into the Malay language were conducted. The test was administered to 195 cancer patients. Reliability was evaluated by testing internal consistency (Cronbach’s α) and calculating the test-retest intra-class correlation coefficient, and validity was examined by determining face, convergent, and discriminant validities and using confirmatory factor analysis (CFA). Results: The Malay version of the PTGI-SF and its five domains demonstrated good internal consistencies and acceptable test-retest reliability. All 10 items of this version were highly correlated with their own domains and thus exhibited convergent validity. Discriminant validity was achieved, as all domains of the Malay PTGI-SF was not highly correlated with the domains of the Source of Social Support Scale. CFA resulted in a bestfitting 5-factor model. Conclusion: The Malay version of the PTGI-SF is a suitable tool for measuring PTG in Malaysian cancer patients.
