A Systematic Review of the Dual Process Model of Coping With Bereavement (1999-2016)

This systematic review addressed the question whether the Dual Process Model of Coping with Bereavement (DPM) accurately represents the bereavement experience, and whether DPM-based interventions are more effective than traditional grief therapy. Twenty databases were searched to identify publications related to the DPM between 1999 and June 30, 2016. Coded material included source, title, research design, research question(s), data source, measures, method, and outcomes. Of the 474 articles initially identified, 86 underwent full-text review, with 22 quantitative or mixed-methods studies included. The DPM accurately represents the bereavement experience and can be used to understand how bereaved individuals cope. Interventions based upon the DPM may be more effective than traditional grief therapy. Further research is needed to test both the model and intervention design, especially in regard to oscillation, with use of consistent measures between studies.
