Spanish Adaptation and validation of the posttraumatic growth inventory-Short Form

Abstract:

The purpose of this article is to adapt and validate the short form of the Posttraumatic Growth Inventory (PTGI-SF) in Spanish. The scale consists of 10 items distributed in 5 posttraumatic growth dimensions measured in the original instrument. The psychometric properties and dimensionality of the scale are examined in a sample of college students (N = 681). Results lend support to the validity and reliability (α = .83) of the PTGI-SF. The dimensions of PTGI-SF show correlations ranging between .29 and .52. In addition, the inventory correlates significantly with deliberate rumination (r = .39) and the search for meaning in life (r = .32). The factor loadings of the items in the confirmatory factor analysis varied between .52 and .87, showing good fit indexes (comparative fit index = .97, Tucker-Lewis index = .93, relative fit index = .90, incremental fit index = .97, normed fit index = .96, and root mean square error of approximation = .05). Multigroup confirmatory factor analysis supported invariance of the PTGI-SF across the 2 groups. Finally, significantly higher PTGI-SF scores were observed in subjects who were actively looking for meaning in life, or had found it after a seeking process, than in subjects who had not looked for meaning in life or had given up because they had not been successful.
