A Systematic Review of Theories of Stress as a Predictor of Intimate Partner Violence.

Abstract

Literature on stress and intimate partner violence (IPV) has primarily focused on stress as an outcome of women's experience of IPV. However, stress may also be a predictor of male-perpetrated IPV. To improve our understanding of how theoretical approaches to stress have been applied to IPV research, we conducted a sub-analysis of a broader systematic review to identify published literature that examines theoretical approaches to stress as a predictor of male-perpetrated IPV. We conducted a search of nine electronic databases and assessed title/abstract and full texts according to pre-defined inclusion and exclusion criteria. Two reviewers categorized included studies into different theoretical groupings and sub-groupings. Data were extracted according to a data extraction template developed for the review, establishing consistency in a pilot data extraction phase. The review identified 27 articles that addressed the following theories of stress: general stress theory, life course theory, occupational stress theory, vulnerability theory, and family stress theory. Each of these sub-theories focuses on different forms of stress, for example, life course theory specifically focuses on stressful early life experiences, including adverse childhood events, whereas occupational stress theory focuses on workplace-related stressors that may result in increased male-perpetrated IPV. Analysis of measurement of stress variables indicated that measurement of stress varies widely across studies and primarily relies on self-reports. Consideration of stress as a predictor of IPV provides important insights into preventable and modifiable targets for intervention. Additional research on mechanisms and pathways between stress and IPV is needed.
