Assessing Positive Changes among Flood Affected Individuals: Translation and Validation of Post-Traumatic Growth Inventory - Short Form (PTGI-SF).
Pak J Med Res Jan ;58(2):59-65.

Objective: To describe and evaluate the efficacy of an Urdu translation of Post-Traumatic Growth Inventory- Short Form (PTGI-SF) that is designed to measure the positive changes in flood affected Individuals. Study type, settings and duration: A cross-sectional population-based study was done on the individuals (who experienced 2010 floods) in Pakistan between March 2012 and June 2012. Subjects and Methods: Sample of 1990 participants was taken from different flood-affected regions that included both men and women (n= 1400 (71.4%), and n= 590 (29.6%)) respectively. The age range of the participants was 16 to 66 years (Mean= 28.25 ? 9.57). Reliability and validity of the PTGI-SF were examined and results of confirmatory factor analysis (CFA) were reported. Results: The translated version of PTGI-SF was described and validation information was provided. The PTG-SF showed high internal consistency with Cronbach`s alpha (?= 0.85) for the total scale. CFA indicated a good fit of the model to the data with all recommended items loading well on respective subscales. The values of lambda ranged from 0.47 to 0.79.The values of fit indices (incremental fit index (IFI)= 0.96; normed fit index (NFI)= 0.94; comparative fit index (CFI)= 0.96; and root mean square error of approximation (RMSEA)= 0.06 were in acceptable range. The factor structure of PTGI-SF scores in our data was consistent with the original scale. It has satisfactory convergent and discriminant validity with measures of wellbeing, rumination, post-traumatic stress, anxiety, depression, and social support. Conclusion: The PTGI-SF Urdu was brief and effective measure for assessing growth, following adversity. The Urdu version of the scale has exhibited sound psychometric properties. Our data CFA supported a five-factor model. It is culturally valid and reliable instrument which can be used in both clinical as well as research settings. However, it can be used with much confidence with the population affected in a natural disaster.
