This study aimed to investigate the impact of a group counseling program on reducing parental stress and depression among mothers of Jordanian children with autism. A purposive sample comprising 40 mothers of children with autism was selected from three autism centers in Zarqa and Rusaifa in Jordan; these participants were then randomly assigned to either an experimental group (N = 20) or control group (N = 20). Participants were asked to complete both the Parental Stress Index-Short Form (PSI-SF; including its three sub-scales) and an amended Arabic version of the Depression, Anxiety and Stress Scale (DASS): pre-and posttest by both groups, and a six-week follow-up test by the experimental group. A CBT-based group counseling program was designed and 14 sessions were held three times per week over a four-week period. The difference between the pre-and posttest scores for the two groups revealed that the experimental group was significantly more likely to have lower levels of parental stress and depression. Furthermore, there was a significant difference in scores between the experimental group's posttest and follow-up assessment: Total Stress (Total PSI), Parental Distress (PD), and depression had all decreased significantly; Parent-Child Dysfunctional Interaction (PCDI) had also decreased, but not significantly; however, although not significantly, stress levels associated with a Difficult Child (DC) had increased. Contribution/Originality: This study confirms the findings of previous studies that CBT-based group counseling is effective in improving the well-being of mothers caring for a child with autism. However, its primary contribution is revealing that alternative, more effective strategies need to be identified for addressing both the stress associated with a difficult child and parent-child dysfunctional interactions. 1. INTRODUCTION Caregivers, especially mothers, of children with autism disorder (AD) who have complex needs often face demands that go far beyond those children with typical development: stigma, physical stress, severe financial difficulties, and ongoing social isolation (Ghunaim & Al-Smadi, 2018; Seltzer et al., 2009). Many studies agree that there is an increased rate of mental disorders among caregivers, indicated by higher feelings of stress, anxiety, and depression reported by caregivers of children with AD. In addition, caregivers reporting more problems with child behavior also revealed increased feelings of stress, anxiety, and depression (Lecavalier, Leone, & Wiltz, 2006; Lovell, Moss, & Wetherell, 2015). There is a good deal of empirical evidence, in fact, that parenting a child with AD is associated with high levels of mental health problems and a low quality of life (Da Paz & Wallander,
