Enhancing Emotion Regulation and Critical Thinking in Hearing-Impaired Individuals through Sensory Integration Therapy: A Randomized Controlled Trial

Abstract

This study aimed to evaluate the effectiveness of Sensory Integration Therapy (SIT) in improving emotion regulation and critical thinking skills in individuals with hearing impairments. A randomized controlled trial was conducted with 30 participants (15 in the intervention group receiving SIT and 15 in the control group). The intervention consisted of ten 75-minute SIT sessions over a two-month period. Emotion regulation and critical thinking were measured at three time points: pre-intervention, post-intervention, and two-month follow-up, using the Difficulties in Emotion Regulation Scale (DERS) and Watson-Glaser Critical Thinking Appraisal (WGCTA), respectively. Data were analyzed using repeated measures ANOVA and Bonferroni post-hoc tests. Significant improvements in emotion regulation were observed in the intervention group from pre-intervention (M = 95.45, SD = 12.78) to post-intervention (M = 81.32, SD = 11.45), and maintained at follow-up (M = 82.67, SD = 12.01). The control group showed no significant changes. For critical thinking, the intervention group’s scores increased significantly from pre-intervention (M = 28.67, SD = 5.23) to post-intervention (M = 36.78, SD = 4.89), and remained high at follow-up (M = 35.54, SD = 4.67). The control group’s scores did not change significantly. ANOVA results indicated significant main effects for time and group for both variables (p < .001), with significant interaction effects (p < .001). Sensory Integration Therapy significantly improves emotion regulation and critical thinking in individuals with hearing impairments, with effects sustained over a two-month follow-up. These findings support the use of SIT as an effective intervention for enhancing cognitive and emotional skills in this population.
