Family therapy for autism: is there research evidence?

In one sentence

This Cochrane review could not find any randomised controlled trials testing whether family therapy improves communication, relationships, or stress for autistic people and their families.

What the researchers did

Autism affects the whole family. Parents and siblings often report high stress, burnout, and difficulty knowing how to respond to challenging behaviour. Family (systemic) therapy aims to improve communication, relationships, and coping — sometimes for the autistic person, sometimes for parents or siblings, sometimes for everyone together.

The reviewers searched major medical databases in January 2017 for randomised or quasi-randomised trials. They looked for any format of family therapy compared with usual care, a wait list, or another psychological treatment, in children, teens, or adults with ASD and their family members.

The search returned 4,809 records. The team read 37 full reports in detail. Two authors screened studies independently, with a third author checking a sample for accuracy.

What they found

• None of the 37 full-text studies met the review’s inclusion criteria for a proper randomised trial of family therapy for ASD.
• One study was still awaiting classification when the review was published, so it could not yet be included in conclusions.
• Because no eligible trials were found, the reviewers could not calculate whether family therapy helps with communication, relationships, coping, or mental health in families affected by autism.
• The authors noted that other types of psychological support — for example, parent training or stress-reduction programs for caregivers — have been studied separately, but those were outside this review’s narrow definition of family therapy.

What this means for families and therapists

Many families already attend family counselling, parent coaching, or systemic therapy and find it helpful in daily life. This review does not mean those experiences are invalid. It means scientists have not yet run the kind of rigorous randomised trials needed to prove benefit for autism specifically.

If you are considering family therapy, it may still be worth trying when a qualified clinician offers a clear plan — especially if stress, conflict, or sibling relationships are affecting everyone. Choose licensed professionals experienced with neurodiversity when possible.

For therapists, the gap is practical: families ask for evidence-based family approaches, but the Cochrane standard — randomised controlled trials — has not yet been met in this area.

Limitations and what we don't know yet

The review is from 2017. Newer trials may exist but were not part of this publication. The absence of evidence is not the same as evidence of no benefit; it reflects a research gap.

The review also excluded non-randomised studies, so positive reports from clinics or case series were not counted. Future trials would need clear outcomes — such as parent stress, sibling wellbeing, or observed communication — and long enough follow-up to guide clinical recommendations.
