A preliminary study exploring the nature of aggression supportive beliefs in a forensic psychiatric sample

Purpose This preliminary study aims to investigate and describe aggression-supportive normative beliefs among patients of a high-secure hospital. Design/methodology/approach Therapy data from a sample of high-secure forensic hospital patients (N = 11) who had participated in Life Minus Violence-Enhanced, a long-term violence therapy, was examined using interpretative phenomenological analysis (IPA). During therapy, cognitions linked to past incidences of aggression were explored using aggression choice chains. Findings IPA was applied to data generated through this process to examine the presence and nature of normative beliefs reported, identifying seven themes: rules for aggressive behaviour; use of violence to obtain revenge; processing emotions with violence; surviving in a threatening world; do not become a victim; using violence to maintain status; and prosocial beliefs. Originality/value Findings demonstrate that forensic patients have specific aggression-supportive normative beliefs, which may be malleable. Limitations and implications are discussed.
