Using a three-phase longitudinal design, the bereavement of 115 adult Australian families following the death of a parent from cancer was studied. The cohort comprised 115 spouses and 153 offspring: 670 individual responses were obtained. A range of psychosocial variables was studied through a semistructured interview covering the experience of the deceased's illness, death and funeral, spousal health, family coping, sources of support, use of ritual and completion of estate duties. Bereavement outcome was measured by standardized questionnaires of the intensity of grief (Bereavement Phenomenology Questionnaire), depression (Beck Depression Inventory), psychological distress (Brief Symptom Inventory) and social adjustment (Social Adjustment Scale). Those psychosocial variables found to be significantly correlated with bereavement outcome were entered into best sub-set regression analyses. Family coping was the most consistent correlate of bereavement outcome in these regression analyses, which accounted for up to 38% of the variance in grief, 64% in distress, 53% in depression and 46% in social adjustment. The nature of family functioning is a key aspect of social support in influencing the outcome of bereavement.
