Factors associated with outcome of cognitive-behavioural therapy for complicated grief: a preliminary study

Complicated grief (CG), also called prolonged grief disorder, is a debilitating condition that can develop following a loss. There is growing evidence that cognitive-behavioural interventions are efficacious in the treatment of CG. The present preliminary study used data from 43 patients with CG who were randomly assigned to cognitive-behavioural therapy in an earlier treatment trial to explore (a) predictors of outcome of cognitive-behavioural therapy for CG and (b) the relationship between symptom improvement and changes in loss-related negative cognitions and avoidance behaviours. Analyses showed that worse treatment outcome was associated with lower education attainment, loss of a partner/child (instead of some other relative), early treatment discontinuation, less patient motivation and more severe CG symptoms at pre-treatment. As predicted, stronger reduction in CG severity was significantly associated with stronger reductions in negative cognitions and avoidance. Implications of these findings are discussed.
