Abstract Introduction: The presence of a child with attention deficit hyperactivity disorder in a family can affect the performance of the family. This study aims to compare social loneliness, marital conflict, and belief in a just world in mothers with and without children with attention-deficit/hyperactivity disorder. Method: The statistical population includes mothers with and without children with attention-deficit/hyperactivity disorder in the year 2022. The research sample includes 400 mothers (200 with Children with Attention Deficit/Hyperactivity Disorder and 200 without Children with Attention Deficit/Hyperactivity Disorder). The participants responded to Ditommaso & et al, Social Loneliness Scale (2004), Sanai's Marital Conflict Questionnaire (2000), and Sutton & Douglas's Belief in a Just World Questionnaire (2005). The data were analyzed using multivariate analysis of variance and SPSS-23 software. Results: The results show that there is a significant difference between mothers with and without children with attention-deficit/hyperactivity disorder in terms of social loneliness, marital conflict, and belief in a just world (p<0.05). Conclusion: Findings emphasize the importance of paying attention to social loneliness, marital conflict, and belief in a just world in mothers with children suffering from attention-deficit/hyperactivity disorder and have an important role in educational interventions.
