Objectives: To determine the effectiveness of auditory integration training (AIT) or other methods of sound therapy in people with autism spectrum disorders (ASD).
Study design: A systematic review was carried out of randomised controlled trials (RCTs) of adults or children with ASD. Meta-analysis was attempted.
Results: Six RCTs of AIT, including one crossover trial, were identified, with a total of 171 participants aged 3–39 years. 17 different outcome measures were used, with only two outcome measures used by three or more studies. Meta-analysis was not possible owing to very high heterogeneity or presentation of data in unusable forms. Three studies did not show any benefit of AIT over control conditions. Three studies reported improvements at 3 months in the AIT group for total mean scores of the Aberrant Behaviour Checklist (ABC), which is of questionable validity. Of these, one study also reported improvements at 3 months in the AIT group for ABC subgroup scores. No significant adverse effects of AIT were reported.
Conclusion: At present there is not sufficient evidence to support its use.
- ABC, Aberrant Behaviour Checklist
- AIT, auditory integration training
- ASD, autism spectrum disorders
- RCT, randomised controlled trial
