Part 1 of this thesis reviews the research literature on psychological interventions for young people with ASD and aggressive behaviour problems (ABPs). Eleven studies in this area were identified which used a controlled research design and included an outcome measure of aggression or irritability. They included parent training programmes, early intensive interaction, cognitive behavioural, behavioural and therapeutic horse-riding interventions. A meta-analysis of all these studies combined (N=602) revealed a moderate treatment effect size suggesting that psychological interventions can reduce the amount of ABPs show by children with ASD. An evaluation of the methodological quality of these studies indicated that further research is needed to strengthen this conclusion. Part 2 reports on the results of an initial evaluation to understand the acceptability and feasibility of a parent-mediated CBT intervention for young people with ASD. It used a mixed-methods and small-N design consisting of a series of multiple systematic case studies (N=7). Baseline and follow-up data were collected. The results provided in depth data for each participant and preliminary evidence that this intervention was acceptable to most families and led to positive changes in anger outbursts for some young people. However, the outcome was variable across participants and so barriers to progress and ways to improve efficacy for a greater proportion of individuals are discussed. Part 3 is a critical appraisal of the research. It includes further discussion of the results and a reflection on the use of a mixed-methods small-N design. It also expands on the limitations of the study and describes some personal reflections on the process of conducting this study.
