Randomised controlled trial of a cognitive narrative intervention for complicated grief in widowhood

The implementation of bereavement interventions is frequently requested, and its effectiveness has been controversial. The aim of this study is to evaluate the effectiveness of a cognitive narrative intervention for complicated grief (CG) for controlling post-traumatic and depressive issues.

The study is a randomised controlled trial and uses the Socio Demographic Questionnaire (SDQ), the Inventory of Complicated Grief (ICG), the Beck Depression Inventory (BDI) and the Impact of Events Scale-Revised (IES-R). There were three phases in the study: (1) The SDQ and CG evaluations were applied to bereaved elders (n = 82). The bereaved elders with the 40 highest ICG values (≥25) were randomly allocated into two groups: the intervention group (n = 20) and control group (n = 20); (2) participants were evaluated using the BDI and IES-R and the IG gave informed consent to participate in an intervention with four weekly 60-min sessions addressing recall, emotional and cognitive subjectivation, metaphorisation and projecting. (3) Two months later, the ICG, BDI and IES-R assessments were repeated.

Outcome measures showed a statistically significant reduction of CG, depressive and traumatic symptoms compared to the controls. Very high effect sizes for the ICG, BDI and IES-R reflect the effectiveness of the intervention along the longitudinal profile.

These results reinforce the importance of brief interventions that combine a reduced number of sessions with lower costs, which is reflected in an increased adherence to the programme along with high effectiveness.
