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

Rast et al. (2025) · American journal on intellectual and developmental disabilities 2025
★ The Verdict

Parent CBT bibliotherapy alone works as well as adding therapist sessions for mild depression and externalizing problems in anxious autistic children.

✓ Read this if BCBAs in outpatient or school clinics serving autistic children with anxiety and mild mood or behavior issues.
✗ Skip if Clinicians treating severe self-injury or crisis-level depression; use functional assessment first.

01Research in Context

01

What this study did

de Jonge et al. (2025) tested a stepped care plan for autistic children who also had anxiety. First, parents read a CBT workbook at home. Next, a therapist added weekly CBT sessions. The team asked: do the extra therapist visits shrink depression or behavior problems more than the book alone?

They tracked kids for three months after the stepped plan ended. No one got a fake treatment; everyone got some form of help.

02

What they found

Both groups showed only small drops in depression and externalizing scores. The added therapist sessions did not beat the parent-book alone.

At the three-month check, the scores looked the same across groups.

03

How this fits with other research

Chalfant et al. (2007) saw big anxiety cuts after 12 weeks of family group CBT. McConachie et al. (2014) also found small anxiety gains with group CBT. Both used full therapist time from the start, unlike the stepped plan.

Floyd et al. (2004) compared CBT book only to full therapy in older adults. They also saw no extra gain from added sessions by three months. The child data now echo that adult pattern.

Coffey et al. (2021) used ABA instead of CBT and still cut problem behavior in autistic kids with anxiety. The new CBT data are weaker, but the kids in Coffey had severe problem behavior, not just mild depression.

Why it matters

If a family is willing to read a CBT workbook, you may not need to rush in a therapist for mild depression or acting-out. Save your scarce therapy hours for kids who do not respond to the book first. Track scores monthly; if they stall, then step up.

03Original abstract

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.
