Abstract

Purpose:

Traumatic events and psychological damage are common, and the assessment of the growth in survivors of these events is critical. This study evaluated the psychometric properties of the Persian Posttraumatic Growth Inventory-Short Form (PTGI-SF).

Methods:

This study was conducted in five phases: (1) forward and backward translation of the questionnaire based on the WHO protocol, (2) confirmatory factor analysis to assess construct validity with 563 participations (288 women and 275 men), aged 19-84 years (mean: 33.36 years), (3) Cronbach's alpha for internal consistency, (4) correlations with the Persian version of the Duke University Religion Index (DUREL) for assessing criterion-related validity, and (5) measurement of invariance across genders.

Results:

Confirmatory factor analysis supported the five-factor model consisting of relating to others, new possibilities, personal strength, spiritual change, and appreciation of life. All the dimensions of the PTGI-SF were moderately associated with the Persian version of the DUREL. The internal reliability of the subscales and full scale of the PTGI-SF were acceptable to satisfactory, and the configural, metric, and scalar invariance was found across genders.

Conclusion:

The Persian version of PTGI-SF is an acceptable, valid, and reliable tool for measuring posttraumatic growth in Iran.
