Medeiros, Emerson Diógenes de Couto, Ricardo Neves Fonsêca, Patrícia Nunes da Silva, Paulo Gregório Nascimento da Medeiros, Paloma Cavalcante Bezerra de Posttraumatic Growth Inventory (PTGI): Adaptation and Factorial Validity in the Brazilian Northeast <p></p><p>Abstract This study aimed to verify the psychometric parameters of the Posttraumatic Growth Inventory - PTGI, presenting evidence of factorial validity, internal consistency and steps of cross-cultural adaptation. The sample consisted of 205 participants from northeastern Brazilian cities, mostly female (59.03%), aged between 18 and 86 years (M = 29.5, SD = 11.4). Participants answered the PTGI, the Life Stressor Checklist - Revised, and demographic questions. The confirmatory factor analysis observed the penta-factorial model as more suitable for PTGI, being statistically superior to three and one-factor. The internal consistency of its factors (Cronbach’s alpha) ranged from .70 to .86, with general alpha of .92, values considered acceptable. It follows that this measurement, providing evidence of construct validity, can be properly used in research in the context in which it was adapted to, however, we recommend the use of the instrument in more heterogeneous samples and conducting other analyzes, observing its factorial invariance.</p><p></p> positive psychology;post-traumatic growth;posttraumatic growth inventory;validity;psychological tests 2017-12-27
