Effects of Stepped Cognitive Behavioral Therapy on Child Depressive and Externalizing Symptoms in Autistic Children With Anxiety.

Researchers studied 76 autistic children with anxiety using a step-by-step treatment approach. All children started with parent-led self-help materials, then some moved to therapist sessions. Both groups saw improvements in depression and behavior problems. Surprisingly, children who stayed with parent-led help did better than those who moved to therapist sessions, but by 3 months later, both groups were doing equally well.

This study examined the effects of a stepped care approach for anxiety treatment on depressive and externalizing symptoms in 76 autistic youth. Participants began with parent-led bibliotherapy for 12 weeks, with 44 children stepping up to therapist-led CBT. Both groups showed reductions in depressive and externalizing symptoms at all assessment points. Interestingly, children who remained in the maintenance phase (parent-led intervention only) showed greater symptom improvements than those who stepped up to therapist-led CBT.

At 3-month follow-up, differences between groups disappeared. Parent mental health measures showed no significant changes throughout the study period.

Stepped care models show promise for treating multiple symptoms in autistic youth with anxiety. Parent-led interventions may be adequate for many families, supporting more accessible treatment delivery. Clinicians should consider that not all children require intensive therapist-led interventions to achieve meaningful improvements in comorbid symptoms.

Sample size appears modest for stepped care design. Study type is unknown, limiting interpretation of methodology quality. No control group comparison reported. Unclear selection criteria for stepping up to therapist-led care, which could introduce bias in comparing intervention intensities.

Despite the strong evidence basis for the treatment of anxiety in autistic youth, accessibility remains a significant challenge. Stepped care addresses this gap, although there is limited research into its broad effects in autistic youth with anxiety. In this project, 76 autistic youth with anxiety entered parent-led-bibliotherapy for 12 weeks; 44 stepped up to receive therapist-led cognitive behavioral therapy (CBT). Those who did not step up entered a maintenance phase.

Youth were assessed for externalizing and depressive symptoms at mid-treatment, post-treatment, and 3 months after treatment (3MFU). Focal symptoms decreased across groups at all timepoints; those who entered maintenance experienced greater decreases. At 3MFU there were no differences between groups. Parents were assessed for depression, anxiety, and stress at the same timepoints; no significant changes were observed.
