Abstract
This study investigated whether parental emotion-regulation difficulties are prospectively associated with increased emotion-regulation challenges in autistic children and adolescents and explored the underlying mechanisms and behavioral implications of these potential intergenerational associations. Over three time points (T1, T2, T3) spanning 2 years, 363 parents of autistic children and adolescents from Hong Kong provided questionnaire data. Path analyses revealed that parental emotion-regulation difficulties at T1 were associated with greater negative emotional expressiveness at T2, which in turn was linked to increased emotion-regulation difficulties and more internalizing and externalizing problems in autistic children and adolescents at T3. Importantly, these findings indicate that when parents have difficulty regulating their emotions and express negativity, their autistic children and adolescents are more likely to face emotion-regulation challenges and exhibit behavior problems. This underscores the need to support parents in regulating their emotions and optimizing their emotional expressiveness. Clinicians and policymakers should help parents strengthen their emotion regulation and enhance their emotional well-being by building coping strategies and fostering supportive environments. By promoting parents' emotional wellness, we may also improve psychological adjustment and behavioral outcomes for their autistic children and adolescents.Lay abstractParents of autistic children and adolescents often experience high levels of parenting stress and face challenges in managing their own negative emotions. These emotional struggles can impact their autistic children and adolescents during everyday interactions, potentially intensifying the emotional and behavioral difficulties they experience. This study examined whether parents' emotion-regulation patterns are longitudinally linked to the development of emotion regulation in their autistic children and adolescents. The findings revealed that when parents had difficulty regulating their emotions and frequently expressed negative emotions, their autistic children and adolescents were more likely to face emotion-regulation challenges and experience personal distress and interpersonal difficulties. This underscores the importance of supporting parents in regulating their emotions and optimizing their emotional expressiveness. Clinicians and policymakers should assist parents in strengthening their emotion regulation and enhancing their emotional well-being by building coping strategies and fostering supportive environments. By promoting parents' emotional wellness, we may also improve psychological adjustment and behavioral functioning for their autistic children and adolescents.
