  1. AUDITORY INTEGRATION TRAINING AND OTHER SOUND THERAPIES FOR ASDARTICLE BY: Sinha et al. (2008) PRESENTED BY: TINA NAAMI, MSW COLLEGE OF SOCIAL WORK UNIVERSITY OF UTAH

  2. STUDY BACKGROUND & OBJECTIVES • AIT was developed by a French national, Bernard in 1982 • AIT requires 10 hrs of listening to electronically modified music (Sinha et al. , 2008) • It is hypothesized that AIT technique will improve abnormal sound sensitivity in individuals with behavioural disorders (autism) • Objective of the study: to determine the effectiveness of AIT or other techniques of sound therapy in autistic individuals

  3. SEARCH STRATEGY Databases searched include: • Cochrane Central Register of Controlled Trials (Cochrane Library Issue 2, 2003) • MEDLINE (1966 to Feb 2002) • EMBASE (1980 to Feb 2002) • CINAHL (1982 to Dec 2001) • PsycINFO (1887 to Feb 2002) • ERIC (1965 to Dec 2001) • LILACS (1982 TO March 2002) • And reference list of published papers

  4. SELECTION CRITERIA • Randomised controlled trials • Population-adults or children with ASD • Intervention was AIT or other sound therapies involving listening to music modified by filtering & modulation • Control groups could be, no treatment, waiting list, usual therapy or placebo equivalent • Outcomes required were changes in core (social interaction, communication, behavioural problems), and associated (auditory processing, quality of life and adverse events) features of ASD

  5. REVIEW METHODS • Selection trials: titles and abstracts were screened by two authors • Studies were evaluated by all the authors for methodological quality based on allocation concealment • Data review manager was used to analyse the studies • Studies with continuous outcome data were included in the research

  6. RESULTS • Only trials assessing AIT were found • Six RCT’s of AIT (one was a cross over-trial) • Total participants were 171 with ages 3-39 years • Four trials had fewer than 20 participants • Allocation concealment was inadequate for all studies • 17 different outcome measures were used • Only two outcomes were used by three or more studies • Meta-analysis was not possible due to high heterogeneity or presentation of data in unusable form • Three studies (Bettison, 1996; Zollweg, 1997; Mudford, 2000) did not show benefit of AIT

  7. RESULTS • Three trials (Veale,1993; Rimland,1995; Edelson,1999) reported improvement in ABC scores for AIT group at 3 months with a questionable validity • Only the Rimland (1995) noted an improvement in ABC subscales in the AIT group at 3 months CONCLUSION “No clear evidence yet for auditory integration therapy’s effect on autism” (Sinha et al., 2008, p. 2)
