Meta-analysis on the effectiveness of parent education for children with disabilities.

Background: Parents of children with disabilities often have difficulty understanding their child's behavior and are unable to do it appropriately because they do not know what to do. The more we properly understand children with disabilities, the more positive the importance of parent education becomes in various aspects.

Aim: To demonstrate the effectiveness of parent education for children with disabilities in various aspects and present it as evidence that can be used clinically.

Methods: For a meta-analysis on the effectiveness of parent education for children with disabilities, literature was collected from 2002 to 2022 using PubMed, Embase, Web of Science, Directory of Open Access Journals, and Europe PMC. Search terms were "disabled children," "disabled children," "parent education," "parent training," and "parent coaching." The final searched literature included a total of 11 articles. To calculate the effect size, the mean, standard deviation, and sample size of the experimental and control groups were analyzed, and a meta-analysis was performed using RevMan version 5.4.1. To analyze statistical heterogeneity, a chi-square test was performed to evaluate the significance of Q statistics to indicate statistical heterogeneity.

Results: The final literature totaled 11 articles, and a total of 4 items were analyzed. There were 5 studies on parental depression, the heterogeneity was 98%, and the effect size for parental depression was 0.35 [confidence interval (CI: 0.30-0.40)], indicating a small but statistically significant effect size. There were 4 studies on parenting attitude, the heterogeneity was 100%, the effect size on parenting attitude was 0.41 (CI: 0.37-0.46), which was a medium effect size, and the value showed a statistically significant score. Additionally, face-to-face parent education was found to have a larger effect size than non-face-to-face education. Regarding parent education methods, face-to-face parent education had a medium effect size [0.57 (CI: 0.52-0.61]), while non-face-to-face parent education had a small effect size [0.23 (CI: 0.18-0.28]).

Conclusion: Parental education has shown high effectiveness in child development, and it has proven to be even more effective when face-to-face parenting education is conducted. Accordingly, more effective and objective data was presented. Based on this study, it is believed that parent education research applying various diagnostic groups should continue to be conducted.
