Relationship between aggression, interpersonal style, and therapeutic alliance during short-term psychiatric hospitalization.

Aggression during psychiatric hospitalization is frequent, problematic, and a major challenge for nurses and mental health services more generally. The strength of the therapeutic alliance between nursing staff and patients has been posited as an important protective factor that can limit the likelihood of aggression. This study examined the relationship between interpersonal style, perceived coercion, and psychiatric symptoms on the therapeutic alliance between patients and staff, and how each, in turn, is related to aggression. Participants in this study were 79 patients admitted to an acute psychiatric hospital. Each participant was interviewed to determine perceived coercion, symptoms of psychiatric illness, interpersonal style, and therapeutic alliance. Incidents of aggression were recorded at discharge through a review of incident forms, file review, and interviews with unit nursing staff. The results showed that a hostile-dominant interpersonal style and symptoms of paranoia predicted poor therapeutic alliance, contributing 14% of the variance in therapeutic alliance scores. A dominant interpersonal style predicted aggression towards staff. Therapeutic alliance, perceived coercion, and symptoms of psychiatric illness did not predict aggression. Implications for engagement in treatment and the prevention of aggression are discussed.
