The bullying of autistic children: A review of anti-bullying interventions, and a feasibility study examining the relationship between bullying victimisation and psychosis-like experiences.

Bullying of autistic children by their peers is prevalent. This is a significant concern given research linking childhood bullying with adverse mental health outcomes, in both autistic and neurotypical groups. The first section of this thesis is a scoping review, which aimed to establish what interventions have been developed to reduce the bullying of autistic children. The second section reports an investigation of the feasibility of examining the relationship between bullying victimisation and psychosis-like experiences (PLEs) in autistic children. Following a systematic literature search 10 studies were identified for inclusion in the scoping review. Broadly, interventions focussed either upon skills-development for autistic children, or the promotion of contact between autistic children and neurotypical peers. There was heterogeneity in the research designs used and outcome measures employed. Overall, the evidence base is in its infancy and there is a need to develop and evaluate multicomponent interventions involving autistic children, neurotypical peers, staff and schools. A quantitative cross-sectional design was used to investigate the feasibility of testing the relationship between bullying victimisation and PLEs in autistic children, and to test the preliminary hypothesis of association between these variables. Parents completed a battery of online questionnaires about their children (N=53). Hierarchical multiple regression was used to test the relationship between the variables of interest, while controlling for: age, sex, family history of psychosis and internalising difficulties. It was found that there is a lack of suitable questionnaires for measuring PLEs in autistic children, and that recruiting a large sample via a clinical service may not be feasible. Preliminary hypothesis testing failed to establish a statistically significant relationship between bullying victimisation and PLEs in autistic children. However, this should not preclude future work in this area.
