Adaptation of the Posttraumatic Growth Inventory in people with HIV from Buenos Aires, Argentina
Abstract
Posttraumatic growth (PTG) involves positive psychological changes resulting from coping with highly challenging circumstances. The Posttraumatic Growth Inventory (PTGI) is the most widespread instrument for its measurement. A substantial proportion of people with HIV experience some degree of PTG as a result of their diagnosis, which is associated with better mental and physical health. The objective was to adapt the PTGI for its use in people with HIV in the Metropolitan Area of Buenos Aires (MABA), Argentina. A preliminary version, linguistically and conceptually equivalent to the original one, was administered to a sample of 100 adults living with HIV from the MABA. According to the confirmatory factor analysis, the original model of five dimensions showed a better fit. Consistently with international evidence, female participants exhibited significantly higher PTG scores, which can be interpreted as external evidence of validity. Reliability and internal consistency of the scale and its dimensions were verified through the ordinal alpha and omega coefficients, obtaining acceptable and excellent values. This version of the PTGI demonstrated acceptable psychometric properties and cultural adequacy for its use in people with HIV from the MABA.
