Dual-Process Bereavement Group Intervention (DPBGI) for Widowed Older Adults

Area of Science:

• Gerontology
• Psychology
• Public Health

Background:

• Widowed older adults experience significant grief, anxiety, and loneliness.
• Existing bereavement interventions may not fully address the complex needs of this population.
• Theory-driven interventions are crucial for effective grief support in older adults.

Purpose of the Study:

• To evaluate the effectiveness of a novel dual-process bereavement group intervention-Chinese (DPBGI-C) for widowed older adults.
• To compare the outcomes of DPBGI-C with a traditional loss-oriented bereavement group intervention-Chinese (LOBGI-C).
• To examine primary and secondary outcomes including complicated grief, anxiety, depression, loneliness, and social support.

Main Methods:

• A cluster-randomized controlled trial involving 12 community centers.
• 125 widowed older adults participated in either DPBGI-C or LOBGI-C over 8 weeks.
• Data collected at preintervention, postintervention, and 16-week follow-up using validated assessments.

Main Results:

• Both interventions improved grief, depression, and social support; DPBGI-C showed larger effect sizes.
• DPBGI-C significantly reduced anxiety, emotional loneliness, and social loneliness, unlike LOBGI-C.
• Significant interactions between intervention type and time were observed for grief and loneliness outcomes.

Conclusions:

• The DPBGI-C is a superior, evidence-based intervention for widowed older adults, demonstrating broader and more impactful results.
• This study provides critical implications for theory development and clinical practice in geriatric bereavement care.
• The findings highlight the effectiveness of tailored, theory-driven interventions for diverse elderly populations.
