Assistance Dogs and Autism
There are a number of significant limitations to all of the research studies published to date. For example
- the majority of the studies (four out of six) had a very small number of participants (between one and 12)
- the majority of the studies (four out of six ) did not use an experimental design (such as a randomised controlled trial)
- the study that did use an experimental design (Groomes et al, 2014) was a non-blinded randomised controlled trial that only included 12 participants.
- the study that used a controlled parental survey (Burgoyne et al, 2014) relied on findings based on self-reports and parents' / guardians' personal perceptions which are subject to participant overestimation, recall bias and possible subject expectancy effects.
