Cost-effectiveness of dialectical behavioural therapy versus treatment as usual for autism with suicidal behaviours: single-blind randomised controlled trial.

ABSTRACT:

Objective

This study evaluated the cost-effectiveness of dialectical behaviour therapy (DBT) compared to treatment as usual (TAU) for autistic adults with suicidal behaviours.

Method

In a randomised controlled trial, 123 autistic outpatients were assessed over 12 months. Healthcare costs and societal costs were calculated in accordance with the Dutch standard. Outcomes were quality-adjusted life years (QALYs) and treatment response, defined as a reduction of at least 50% in symptoms of suicidal ideation from t₀-t₁₂ as measured by the Suicidal Ideation Attributes Scale (SIDAS), plus achieving SIDAS < 20 at t₁₂ (i.e. below the clinical threshold).

Results

From the healthcare perspective, DBT cost €371 less than TAU while gaining an addit
