Effectiveness of bereavement counselling through a community-based organization: A naturalistic, controlled trial.

This controlled, longitudinal investigation tested the effectiveness of a bereavement counselling model for adults on reducing complicated grief (CG) symptoms. Participants (N = 344; 79% female; mean age: 49.3 years) were adult residents of Scotland who were bereaved of a close relation or partner, experiencing elevated levels of CG, and/or risks of developing CG. It was hypothesized that participants who received intervention would experience a greater decline in CG levels immediately following the intervention compared to the control participants, but the difference would diminish at follow-up (due to relapse). Data were collected via postal questionnaire at 3 time points: baseline (T), post-intervention (T + 12 months), and follow-up (T + 18 months). CG, post-traumatic stress, and general psychological distress were assessed at all time points. Multilevel analyses controlling for relevant covariates were conducted to examine group differences in symptom levels over time. A stepwise, serial gatekeeping procedure was used to correct for multiple hypothesis testing. A main finding was that, contrary to expectations, counselling intervention and control group participants experienced a similar reduction in CG symptoms at postmeasure. However, intervention participants demonstrated a greater reduction in symptom levels at follow-up (M = 53.64; d = .33) compared to the control group (M = 62.00). Results suggest community-based bereavement counselling may have long-term beneficial effects. Further longitudinal treatment effect investigations with extensive study intervals are needed.
