Yes Cochrane Collaboration is definitely a very reputable source, seen globally as highly impartial and a 'gold standard' of research. I extracted all the summaries they have written about interventions for autism, if anyone is interested, and really ABA comes out pretty much best - albeit it is a guarded recommendation (but if you read them all, you'll see that a guarded recommendation is about as good as it gets). You'll notice they haven't reviewed OT or SALT, despite those being the most common NHS offerings for autism, though Research Autism is honest enough to admit on its site that there's zero evidence for either with autism, but 'people seem to like them'.

Authors' Conclusions - 2010
Music therapy may help children with ASD to improve their skills in important areas such as social interaction and communication. Music therapy may also contribute to increasing social adaptation skills in children with ASD and to promoting the quality of parent-child relationships. Some of the included studies featured interventions that correspond well with treatment in clinical practice. More research with adequate design and using larger numbers of patients is needed. It is important to specifically examine how long the effects of music therapy last. The application of music therapy requires specialised academic and clinical training. This is important when applying the results of this review to practice.
AUTHORS' CONCLUSIONS - 2010: There is no evidence of effect of SSRIs [Prozac] in children and emerging evidence of harm. There is limited evidence of the effectiveness of SSRIs in adults from small studies in which risk of bias is unclear.
Authors' conclusions - 2013
The review finds some evidence for the effectiveness of parent-mediated interventions, most particularly in proximal indicators within parent-child interaction, but also in more distal indicators of child language comprehension and reduction in autism severity. Evidence of whether such interventions may reduce parent stress is inconclusive. The review reinforces the need for attention to be given to early intervention service models that enable parents to contribute skilfully to the treatment of their child with autism. However, practitioners supporting parent-mediated intervention require to monitor levels of parent stress. The ability to draw conclusions from studies would be improved by researchers adopting a common set of outcome measures as the quality of the current evidence is low.
AUTHORS' CONCLUSIONS - 2012
There is some evidence that EIBI is an effective behavioral treatment for some children with ASD. However, the current state of the evidence is limited because of the reliance on data from non-randomized studies (CCTs) due to the lack of RCTs. Additional studies using RCT research designs are needed to make stronger conclusions about the effects of EIBI for children with ASD.
Early Intensive Behavioral Intervention (EIBI) for kids with Autism
A specific form of behavioral intervention, referred to as Early Intensive Behavioral Intervention (EIBI), is a highly structured teaching approach for young children with ASD. A recent Cochrane Review suggests that EIBI is an effective treatment for children with ASD. The evidence points to gains in the areas of IQ, adaptive behavior, socialization, communication, and daily living skills; with the largest gains made in IQ and the smallest in socialization.
AUTHORS' CONCLUSIONS - 2008: Research has shown of high rates of use of complementary and alternative therapies (CAM) for children with autism including gluten and/or casein exclusion diets. Current evidence for efficacy of these diets is poor. Large scale, good quality randomised controlled trials are needed.
Authors' conclusions - 2012
There is some evidence that social skills groups can improve social competence for some children and adolescents with ASD. More research is needed to draw more robust conclusions.
Authors' conclusions - 2014
While there is some evidence that Theory of Mind (ToM), or a precursor skill, can be taught to people with ASD, there is little evidence of maintenance of that skill, generalisation to other settings, or developmental effects on related skills. Furthermore, inconsistency in findings and measurement means that evidence has been graded of 'very low' or 'low' quality and we cannot be confident that suggestions of positive effects will be sustained as high-quality evidence accumulates. Further longitudinal designs and larger samples are needed to help elucidate both the efficacy of ToM-linked interventions and the explanatory value of the ToM model itself. It is possible that the continuing refinement of the ToM model will lead to better interventions which have a greater impact on development than those investigated to date.
Authors' conclusions - 2007
Due to the small number of studies, the methodological quality of studies, and small sample sizes, no recommendation can be advanced regarding the use of B6-Mg as a treatment for autism.
Authors' conclusions - 2007
Risperidone can be beneficial in some features of autism. However there are limited data available from studies with small sample sizes. In addition, there lacks a single standardised outcome measure allowing adequate comparison of studies, and long-term followup is also lacking. Further research is necessary to determine the efficacy pf risperidone in clinical practice.
Authors' conclusions - 2011
There is no evidence that auditory integration therapy or other sound therapies are effective as treatments for autism spectrum disorders. As synthesis of existing data has been limited by the disparate outcome measures used between studies, there is not sufficient evidence to prove that this treatment is not effective. However, of the seven studies including 182 participants that have been reported to date, only two (with an author in common), involving a total of 35 participants, report statistically significant improvements in the auditory intergration therapy group and for only two outcome measures (Aberrant Behaviour Checklist and Fisher's Auditory Problems Checklist). As such, there is no evidence to support the use of auditory integration therapy at this time.
Authors' conclusions - 2011
Current evidence does not support the use of acupuncture for treatment of ASD. There is no conclusive evidence that acupuncture is effective for treatment of ASD in children and no RCTs have been carried out with adults. Further high quality trials of larger size and longer follow-up are needed.
Authors' conclusions - 2011
To date there is no high quality evidence that omega-3 fatty acids supplementation is effective for improving core and associated symptoms of ASD. Given the paucity of rigorous studies in this area, there is a need for large well-conducted randomised controlled trials that examine both high and low functioning individuals with ASD, and that have longer follow-up periods.
Authors' conclusions - 2012
There is no evidence that single or multiple dose intravenous secretin is effective and as such currently it should not be recommended or administered as a treatment for ASD. Further experimental assessment of secretin's effectiveness for ASD can only be justified if there is new high-quality and replicated scientific evidence that either finds that secretin has a role in neurotransmission in a way that could benefit all children with ASD or identifies important subgroups of children with ASD who could benefit from secretin because of a proven link between the action of secretin and the known cause of their ASD, or the type of problems they are experiencing.
Authors' conclusions - 2012
Evidence from two randomized controlled trials suggests that aripiprazole can be effective in treating some behavioral aspects of ASD in children. After treatment with aripiprazole, children showed less irritability, hyperactivity, and stereotypies (repetitive, purposeless actions). Notable side effects must be considered, however, such as weight gain, sedation, drooling, and tremor. Longer studies of aripiprazole in individuals with ASD would be useful to gain information on long-term safety and efficacy.
Authors' conclusions - 2012
Clinicians considering the use of TCAs [Tricyclic anti depressants] need to be aware of the limited and conflicting evidence of effect and the side effect profile when discussing this treatment option with people who have ASD and their carers. Further research is required before TCAs can be recommended for treatment of individuals with ASD.
