Why we cite it
Seminal theoretical paper proposing the Dual Process Model (DPM) of coping with bereavement, which challenges the "grief work hypothesis" and linear stage models. Identifies loss-oriented and restoration-oriented stressors and proposes that healthy coping involves oscillation between confronting and avoiding these stressors. Became the dominant theoretical framework in bereavement research (~1,370 citations). Relevant to the project's behavior-change framework: the oscillation concept applies to habit change — moving between old and new behaviors is normal and adaptive, not failure.
