This study aimed to examine the effectiveness of play therapy in improving sensory processing and distress tolerance in adolescents with mild intellectual disabilities. A randomized controlled trial was conducted with 30 adolescents aged 12 to 17 years, randomly assigned to either an intervention group (n = 15) receiving eight 90-minute sessions of play therapy or a control group (n = 15) receiving no intervention. Sensory processing and distress tolerance were assessed at baseline, post-intervention, and five-month follow-up using standardized measures. Data analysis was performed using repeated-measures analysis of variance (ANOVA) and Bonferroni post-hoc tests in SPSS-27 to evaluate within-group and between-group differences over time. The results indicated a significant main effect of time for both sensory processing (F(2, 84) = 92.32, p < 0.001) and distress tolerance (F(2, 84) = 111.60, p < 0.001), demonstrating substantial improvements across timepoints. The intervention group showed a notable increase in sensory processing scores from baseline (M = 48.72, SD = 5.91) to post-intervention (M = 64.15, SD = 6.38) and follow-up (M = 69.03, SD = 5.79), whereas the control group exhibited minimal change. Similarly, distress tolerance scores improved significantly in the intervention group (baseline: M = 42.85, SD = 6.27; post-intervention: M = 58.74, SD = 5.69; follow-up: M = 63.92, SD = 6.08), with no substantial improvement in the control group. The Bonferroni post-hoc test confirmed significant pairwise differences between baseline and subsequent assessments. Play therapy was found to be an effective intervention for enhancing sensory processing and distress tolerance in adolescents with mild intellectual disabilities, with improvements sustained at follow-up. These findings suggest that play-based interventions can be a valuable therapeutic approach for promoting sensory integration and emotional regulation in this population.

The present study was conducted to design and validate the model of exit from organizational mobbing in the Education Organization. It is an applied-developmental research. In terms of how to collect data, it is a cross-sectional survey. To achieve the research purpose, the exploratory mixed research design was employed. Qualitative meta-synthesis was used to identify the model categories and the partial least squares approach was utilized to validate the model. Data analysis in the qualitative phase was conducted via Maxqda software and in the quantitative phase via the Smart PLS software. The statistical population included managers and employees of the Education Organization. The sample volume was estimated equal to 140 persons by means of Cohen's statistical power analysis. Cluster-random sampling was used for sampling. Finally, the final indicators were categorized into 13 main categories and 72 subcategories. Conflict management and stress management led to exit from organizational mobbing in the Education Organization through improving the professional capability of employees, organizational intimacy, and emotional intimacy.
