Adaptive Humor Styles as Predictors of Post-Traumatic Growth Factors

This study examined whether adaptive humor styles, affiliative and self-enhancing, predict the five dimensions of post-traumatic growth (PTG) in a sample of South African undergraduate students who had experienced trauma. A cross-sectional SEM design was used with a criterion sample of 194 South African undergraduate students (72.7% female; M = 21.06 years, SD = 1.84) who had experienced a traumatic event between one and five years before participation. Self-enhancing humor was a significant positive predictor of all five PTG dimensions (Relating to Others, New Possibilities, Personal Strength, Spiritual Change, and Appreciation of Life), with standardized path coefficients ranging from β = 0.324 to β = 0.477. The measurement model demonstrated acceptable fit, though CFI (0.870) fell marginally below the conventional 0.90 threshold, likely due to model complexity. Affiliative humor did not independently predict any PTG dimension, with its zero-order correlations accounted for by shared variance with self-enhancing humor. These findings suggest that the emotion regulation and cognitive reappraisal functions of self-enhancing humor may facilitate growth across multiple domains following trauma, and have implications for therapeutic interventions aimed at promoting PTG.
