Dual Process Model of Grief

Core mechanism: Healthy adaptation requires dynamic oscillation between loss-oriented coping (processing grief) and restoration-oriented coping (rebuilding life); rigid fixation in either mode produces complications

Ontology: Grief is not a state to move through but a dynamic oscillation between confronting loss and rebuilding life; pathology emerges from rigidity, not from the pain itself

Worden's Task Model of Mourning

Core mechanism: Active engagement with four developmental tasks transforms acute grief into integrated loss; failure to accomplish tasks results in complicated mourning

Ontology: Grief is active work requiring engagement, not a passive process to endure; complicated grief results from incomplete task accomplishment

Dual Process Model of Grief

Philosophical roots: Lazarus & Folkman (coping as process); Bowlby (attachment and loss); Worden (task model as precursor); regulatory flexibility research (Bonanno); gender role socialization and grief

Blind spots: Descriptive rather than prescriptive: tells clinicians what healthy grief looks like but less guidance on what to do when someone is stuck; cultural assumptions about individual coping may not map to collective grief practices; as with Worden, pushing a client to oscillate on cue is a misapplication rather than a contraindication, since the model describes movement, it does not prescribe it

Therapeutic voice: Some days you need to sit with the grief. Other days you need to do your taxes and clean the kitchen. Both are grief work. The back and forth isn't a sign you're doing it wrong: it's exactly how this works.

Worden's Task Model of Mourning

Philosophical roots: Bowlby (attachment and loss); Klass, Silverman & Nickman (continuing bonds); Stroebe & Schut (dual process model as complement); Parkes (psychosocial transitions)

Blind spots: Task model can imply a normative sequence that doesn't match all cultural grief expressions; can pathologize grief that doesn't follow expected trajectory; limited attention to systemic and disenfranchised grief; applying the tasks as a fixed sequence is a clinician error rather than a contraindication, since the framework is not unsafe when it is forced, it is simply no longer the framework

Therapeutic voice: You keep saying you should be further along by now. I don't think grief runs on a schedule, but I do think there's work in it. And right now it sounds like some part of you is still listening for his key in the door. Can we stay with that for a minute?
