Background: Health encompasses physical, mental, emotional, intellectual, spiritual, and social dimensions. Parents' spiritual well-being can affect their social health and, therefore, their health-related quality of life (HRQOL). Objectives: In this study, we investigated the relationship between spiritual well-being, social health, parent-child interaction, and HRQOL in parents of children with specific learning disorders. Methods: This study investigated the relationship between spiritual well-being, social health, and the statistical population in this descriptive-correlational study comprised all parents of children with certain learning disorders in Andimeshk, Iran, in 2020. Through convenience sampling, 174 parents were selected as the sample. The study used instruments, including the Health-related Quality of Life Questionnaire, the Spiritual Well-being Questionnaire, Keyes's Social Wellbeing Questionnaire (KSWBQ), and the Pianta Child-Parent Relationship Scale (CPRS). Statistical analysis of the data was conducted using Pearson correlation coefficients and simultaneous regression models. Results: There was a significant positive relationship between HRQOL and spiritual well-being, social health, and parent-child interaction (P < 0.001). In addition, the regression analysis demonstrated multiple correlations between HRQOL and spiritual well-being, social health, and parent-child interaction (R = 0.48, P < 0.001). Conclusions: The study found that spiritual well-being, social health, and parent-child interactions were essential in the HRQOL of parents of children with specific learning disabilities.
