Objective: This study aimed to investigate the relationship between humor and stress in families, with positive affect as a mediating variable. Methods and Materials: The study employed a descriptive correlational design with 409 participants selected from families in South Africa, based on the Morgan and Krejcie sample size table. Data were collected through standardized questionnaires measuring humor, stress, and positive affect. Pearson correlation analysis was conducted using SPSS-27 to explore bivariate associations among variables. Structural Equation Modeling (SEM) was performed in AMOS-21 to test the hypothesized mediation model. Model fit was evaluated using multiple indices, including χ², df, χ²/df, GFI, AGFI, CFI, TLI, and RMSEA. Findings: The results revealed significant correlations between the study variables. Humor was positively correlated with positive affect (r = 0.53, p < .001) and negatively correlated with stress (r = −0.41, p = .001). Stress showed a significant negative correlation with positive affect (r = −0.47, p < .001). The structural model demonstrated acceptable fit (χ²(61) = 124.36, χ²/df = 2.04, GFI = 0.93, AGFI = 0.90, CFI = 0.96, TLI = 0.95, RMSEA = 0.049). Path analysis confirmed that humor had a direct positive effect on positive affect (β = 0.39, p < .001) and a negative effect on stress (β = −0.34, p = .001). Stress negatively influenced positive affect (β = −0.28, p < .001). Positive affect mediated the relationship between humor and stress, with a significant indirect effect (β = 0.09, p = .002). Conclusion: The findings highlight the protective role of humor in family contexts, showing that it reduces stress both directly and through the mediating role of positive affect. Integrating humor into family-based interventions may enhance resilience and emotional well-being.

Objective: This study aimed to evaluate the effectiveness of Acceptance and Commitment Therapy (ACT) in reducing negative affect, improving emotional processing, and enhancing psychological hardiness in women experiencing domestic violence. Methods and Materials: A randomized controlled trial was conducted with 30 participants, divided equally into intervention and control groups. The intervention group underwent eight 90-minute ACT sessions over eight weeks, while the control group received no treatment. Outcomes were assessed at pre-intervention, post-intervention, and five-month follow-up stages using validated tools for Negative Affect, Emotional Processing, and Psychological Hardiness. Data were analyzed using repeated-measures ANOVA and Bonferroni post-hoc tests, with SPSS-27. Findings: Significant improvements were observed in the intervention group across all variables. For Negative Affect, mean scores decreased from 3.52 (SD = 0.45) at pre-intervention to 2.89 (SD = 0.39) post-intervention and 2.45 (SD = 0.33) at follow-up (F(1,28) = 30.19, p = 0.001, η² = 0.52). Emotional Processing scores increased from 3.20 (SD = 0.40) to 3.80 (SD = 0.37) post-intervention and 4.25 (SD = 0.31) at follow-up (F(1,28) = 34.38, p = 0.001, η² = 0.55). Psychological Hardiness improved from 3.15 (SD = 0.38) to 3.95 (SD = 0.35) post-intervention and 4.10 (SD = 0.32) at follow-up (F(1,28) = 36.57, p = 0.001, η² = 0.58). The control group showed minimal changes across all measures. Conclusion: ACT was highly effective in reducing negative affect, improving emotional processing, and enhancing psychological hardiness in women experiencing domestic violence. The results suggest that ACT is a valuable therapeutic approach for this population, with sustained benefits over time.
