The concept of sound temporal personality and its relationship with posttraumatic growth

Abstract Personality traits can influence posttraumatic growth (PTG). However, limited research has examined the relationship between temporal personality and PTG. From a positive perspective on temporal personality, this study explores whether a sound temporal personality (STP, a generalized and adaptive form of temporal personality) impacts PTG in daily life. In Study 1, an item pool for the STP scale was developed through an open‐ended questionnaire ( N = 208) and in‐depth interviews ( N = 17). The scale was then confirmed through exploratory ( N = 539) and confirmatory factor analyses ( N = 777) as well as reliability and validity tests ( N = 440). Study 2 employed ecological momentary assessment (EMA) ( N = 80) to investigate the relationship between STP and PTG in daily life. The STP scale demonstrated good reliability and validity, significantly predicting PTG in daily life. At the within‐person level, STP had a significant positive impact on PTG. At the between‐person level, STP significantly predicted PTG across multiple time points.
