The role of cognition in understanding the sleep- aggression relationship in a forensic psychiatric sample

Abstract

This PhD program of work focused on the role of cognition in the sleep-aggression relationship relating to both aggression towards others and towards the self (i.e. self-injury). The research aimed to develop a preliminary model to explain the potential contribution of cognition in this complex relationship. Research methodology included a systematic literature review, qualitative interviews, a cross-sectional study and an intervention study comparing Mindfulness, Sleep Hygiene Education, and Treatment as Usual (control). The empirical studies were conducted with high secure psychiatric patients. Findings indicate that cognition is multifaceted in the relationship between sleep and aggression. Interventions to improve sleep should be tailored to individual needs and consider the cognitive factors contributing to both sleep and aggression. The preliminary model outlined acknowledges the contribution of a range of cognitions.
