Enhancing Self-Determination and Working Memory in Individuals with Visual Impairments: Efficacy of Social Skills Training

Abstract

This study aimed to evaluate the effectiveness of social skills training on enhancing self-determination and working memory in individuals with visual impairments.

A randomized controlled trial design was used, involving 40 participants with visual impairments, randomly assigned to an intervention group (n = 20) and a control group (n = 20). The intervention group underwent ten 60-minute sessions of social skills training over four months, while the control group received no specific intervention. Self-determination was assessed using the Self-Determination Inventory: Student Report (SDI), and working memory was measured using the Working Memory Questionnaire (WMQ). Data were collected at pre-intervention, post-intervention, and a four-month follow-up. Analysis of variance (ANOVA) with repeated measures and Bonferroni post-hoc tests were conducted using SPSS version 27. Participants in the intervention group showed significant improvements in self-determination from pre-intervention (M = 45.25, SD = 6.34) to post-intervention (M = 58.43, SD = 5.27) and at the four-month follow-up (M = 55.37, SD = 5.82). Similarly, working memory scores improved from pre-intervention (M = 39.18, SD = 7.24) to post-intervention (M = 51.22, SD = 6.05) and were maintained at follow-up (M = 48.76, SD = 6.50). The ANOVA results indicated significant main effects for self-determination (F(2, 76) = 41.52, p < .001, η² = 0.53) and working memory (F(2, 76) = 38.19, p < .001, η² = 0.50), as well as significant time x group interaction effects (self-determination: F(2, 76) = 32.35, p < .001, η² = 0.46; working memory: F(2, 76) = 31.88, p < .001, η² = 0.45). The findings demonstrate that social skills training is significantly effective in enhancing self-determination and working memory in individuals with visual impairments. These improvements were sustained over a four-month follow-up period, suggesting the potential of such interventions to positively impact cognitive and social functioning in this population.
