• Narrative review of mental health interventions for parents of autistic children • Some treatments reported improvements in stress, depression, and anxiety.• Post-test produced weaker effects than follow-up assessments two months and beyond.• Small sample size, homogeneity, and self-report limited generalizability of results • Outcomes encouraging, but existing data cannot yet support definitive conclusions a b s t r a c t a r t i c l e i n f o Prevalence of autism spectrum disorders (ASD) suggest that one in 68 children is affected. With convincing evidence that parenting a child with ASD is associated with elevated distress and mental health problems, researchers have begun to investigate treatments that directly target parents' psychological well-being. We conducted a narrative review of studies that empirically tested the effects of interventions targeting improvements in the mental health of parents of children with ASD. Following a range of search strategies, a total of 13 studies, seven randomized controlled trials (RCTs) and six pre-post test designs, met inclusion criteria. We calculated and reported effect sizes for all RCTs. On average, treatment produced medium to large effect sizes with improvements in parenting stress and general health, and reductions in depression and anxiety. Interventions that appeared promising included: Stress Management and Relaxation Techniques, Expressive Writing, MindfulnessBased Stress Reduction, and Acceptance and Commitment Therapy. However, only one study conducted a followup assessment N 3 months post intervention. Study populations primarily consisted of English-speaking mothers, ages 39 to 42 years. Conclusions were limited by small sample sizes, homogeneity of sample population, and reliance on self-report. Therefore, this body of research contains significant limitations in need of improvement for this field to move forward and benefit a sizable number of parents.

Psychological adjustment to having one's child diagnosed with an autism spectrum disorder has important implications for a parent's mental health. In a longitudinal study, we examined the association between maternal adjustment to the diagnosis and measures of distress and well-being in 90 mothers of children with autism (baseline and 18 months). We used a novel 30-item scale "Adjustment to the Diagnosis of Autism." Factor analysis identified three dimensions of adjustment: acceptance, self-blame, and despair. Acceptance appeared to be a protective response, as it was associated with lower depressive symptoms, cross-sectionally and over time. Conversely, caregivers with increasing levels of self-blame and despair about the diagnosis over 18 months had worsening of mental health and satisfaction with life during this period.
