Family harmony is an ideal condition desired by all children. However, not every child has the opportunity to experience a harmonious family environment. One of the main factors that contributes to negative emotional states and lower quality of life in children—particularly adolescents—is parental divorce. Negative emotions can interfere with the development and maintenance of a childs subjective well-being. For adolescents affected by parental divorce, the ability to forgive may help mitigate the adverse effects of a broken home. This study aims to examine the effect of forgiveness on subjective well-being among late adolescents from broken home families. The research employed a quantitative approach. The participants were late adolescents aged 18 to 21 years whose parents were divorced. Subjective well-being was measured using the Positive and Negative Affect Schedule (PANAS) and the Satisfaction with Life Scale (SWLS). Forgiveness was assessed using the Transgression-Related Interpersonal Motivations Inventory (TRIM-18). A snowball sampling technique was employed, resulting in a total sample of 126 respondents. Data analysis was conducted using simple linear regression, with the aid of Statistical Product and Service Solutions (SPSS) version 22 for Windows. The results showed no significant effect of forgiveness on the cognitive dimension of subjective well-being, specifically life satisfaction. However, forgiveness was found to have a highly significant effect on the affective dimensions of subjective well-being, namely positive affect and negative affect. Therefore, it can be concluded that forgiveness does have a significant influence on subjective well-being among late adolescents with divorced parents.
