Meta-analysis on the Safety Skill Training of Individuals with Intellectual Disabilities

ABSTRACT Since individuals with intellectual disabilities are vulnerable to injury, they should be aware of potential dangers and develop skills to protect themselves from possible injury. This study verifies the effects of group safety skill training on individuals with intellectual disabilities. Meta-analytical procedures were used to identify and synthesise articles for analysis. The study summarised the empirical literature on safety training that was examined using group design and published between 2001 and 2018. The standard mean difference was used to interpret effect sizes and quantify individual research findings; further, coding procedures recorded various moderators. A total of 423 individuals participated in the group intervention. Among 12 selected studies, 11 were analysed. The results of meta-analyses indicated an overall medium effect, and moderator analyses verified the factor affecting the group safety skill training’s effectiveness. All moderators showed significant differences in effect size. Therefore, future safety skill training research should consider significant moderators.
