ABSTRACT
People with mental illness experience significant health disparities, including morbidity and premature mortality. Evidence suggests that stigma is a contributing factor to these observed inequities. The tripartite conceptualization of stigma proposes that three problems underlie stigma: problems of knowledge (ignorance), attitudes (prejudice) and behaviour (discrimination). There is limited prior research concerning stigma towards mental illness among nurses in the United States (US). The aims of this study were to assess stigma among US nurses towards patients with mental illness, compare the stigma expressed by nurses working in medical/surgical settings with mental health settings, and identify factors associated with stigma. Participants were recruited online from national professional nursing organizations in the US. We collected demographic data and administered measures of mental health stigma and stigma-related mental health knowledge. Mental health nurses demonstrated comparatively lower levels of stigma and higher levels of knowledge than the medical/surgical nurses. Nursing speciality and personal contact with mental illness were the most significant predictors of stigma and knowledge. Knowledge was found to partially mediate the relationship between nursing speciality and stigma. We found support for the 'contact hypothesis', that is, having a personal experience of mental illness or a friend or family member who has a mental illness is associated with lower stigma towards mental illness. These findings support the development of contact-based and educational anti-stigma interventions for nurses in order to reduce stigma towards mental illness.
