Therefore, this study aims to identify the social engagement of orphans in Pahang orphanages. Besides, this study examines the relationship and significant differences between demographic factors (gender, age, and years of living in orphanages) and social engagement among the orphans in Pahang orphanages. The questionnaire was distributed to 270 orphans aged 8 to 17 years old at 12 orphanages in Pahang, Malaysia. To test research objectives, Statistical Package for the Social Sciences (SPSS) was used in generating the descriptive result, regression and Analysis of Variance (ANOVA). The result shows that the overall social engagement in Pahang orphanages is considered moderately high. Besides, the result revealed that gender and years of living in orphanages have an impact on social engagement. For these results, there is a need for the policymakers to organize more programs between orphans and society by considering the gender and years of living in orphanages to support the National Children's Mental and Well-being Strategy.
