Effectiveness of psychosocial interventions in reducing grief experienced by family carers of people with dementia: a systematic review protocol

Pre-loss group therapy for dementia family care partners at risk for complicated grief

INTRODUCTION

Dementia family caregiving may span more than a decade and places many family care partners (CPs) at risk for poor bereavement outcomes; estimates of complicated grief in bereaved dementia family CPs range from 10% to 20%. We adapted our efficacious complicated grief group therapy intervention for bereaved dementia caregivers for soon-to-be bereaved dementia CPs at risk for complicated grief to facilitate healthy death preparedness and eventual bereavement-pre-loss group therapy (PLGT).

METHODS

In this Stage IB pilot intervention study, we implemented and evaluated PLGT in three psychotherapy group cohorts with family CPs at-risk for complicated grief whose person living with dementia (PLWD) had a life expectancy of 6 months or less and resided in a nursing home. PLGT is a 10-session multi-modal psychotherapy administered by social workers.

RESULTS

Participants in PLGT realized significant improvement in their pre-loss grief and in reported preparedness for the death of their family member, and participants evidenced lowered pre-loss grief severity and improvement, as measured by facilitators. Participants also realized significant improvement in meaning making, particularly as a sense of peace and a reduction of loneliness.

DISCUSSION

The process and treatment elements of the PLGT intervention affirm the value of specialized care for those dementia family CPs at risk for complicated grief, as the PLGT groups demonstrated a steady progression toward improvement collectively and individually. PLGT participants realized statistical and clinical improvement across pre-loss grief measures suggesting that their risk for complicated grief risk was mitigated, and they were better prepared for the death of their PLWD.

Resilience in Bereaved Caregivers of Persons With Dementia

The purpose of the current study was to identify characteristics of resilience using surveys in 50 bereaved caregivers for persons with dementia who lost their care recipient in the past 6 months. Surveys were reviewed and sorted as demonstrating a resilient grieving process or a problematic grieving process. Resilience was defined as the ability to adapt in a positive direction, with adequate support resources in place despite destabilizing experiences. Following initial review and sorting, 19 resilient surveys were coded and grouped according to phrases. Using the qualitative descriptive analysis process, five themes of resilience were derived from these surveys. Themes of resilience included: Relationships, Spirituality, Formal Support, Honor, and Relief. The use of these themes was noted to be supportive of a positive grief experience. The information provided in the current study serves to inform clinical nurses on resilient attributes to support bereaved caregivers for persons with dementia to improve grief outcomes.

Effectiveness of psychosocial interventions in reducing grief experienced by family carers of people with dementia: a systematic review

BACKGROUND

Family carers of people living and dying with dementia experience grief. The prevalence, predictors and associated factors of grief in this population have been identified, and psychosocial interventions to decrease grief symptoms have been implemented. However, the effect of psychosocial interventions on family carers' grief, loss or bereavement has not been examined.

OBJECTIVE

To synthesize the existing evidence regarding the impact of psychosocial interventions to assist adjustment to grief, pre- and post-bereavement, for family carers of people with dementia.

INCLUSION CRITERIA TYPES OF PARTICIPANTS

Family carers of older persons with dementia (>65 years).

TYPES OF INTERVENTIONS

Psychosocial interventions in health and social care facilities, and community settings designed to assist family carers adjust to grief during the dementia trajectory and/or following death.

COMPARISONS

No treatment, standard care or treatment as usual, or an alternative intervention.

TYPES OF STUDIES

Experimental and epidemiological study designs.

OUTCOMES

Grief in family carers including anticipatory, complicated and prolonged grief disorder measured with validated instruments.

SEARCH STRATEGY

A three-step strategy sought to identify both published and unpublished studies from 1995.

METHODOLOGICAL QUALITY

Assessed by two independent reviewers using standardized critical appraisal tools from the Joanna Briggs Institute Meta Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI).

DATA EXTRACTION

The standardized data extraction tool from JBI-MAStARI was used by two reviewers independently.

DATA SYNTHESIS

Statistical pooling of results was not possible due to the heterogeneity of the interventions and the outcome measures.

RESULTS

Data were extracted from three studies. Study designs were a randomized controlled trial; a pre-test, multiple post-test quasi-experimental; and a single group, repeated measures. The interventions were multi-component, had durations of nine to 26 weeks and were delivered while care recipients were alive. All studies were undertaken in the United States. There were 327 family carers, of which 197 received a psychosocial intervention. Family carers were predominantly female (84.7%), Caucasian (73.4%) and caring for their spouse (44.3%). All care recipients had dementia; 68.5% had Alzheimer's disease. Two studies measured anticipatory grief, and the third study reported normal and complicated grief.Moderate benefits to anticipatory grief were evident upon completion of the "Easing the Way" intervention (effect size -0.43, P = 0.03). After controlling for research design and control variables, for every hour increase in the interventions focusing on family carers' cognitive skills, there were associated decreases in carers' normal grief (parameter estimate [PE] = -0.81, P = 0.02) and complicated grief (PE = -0.87, P = 0.03). For every hour increase in the interventions focusing on carer behavior, there was an associated decrease in carers' complicated grief (PE = -1.32, P = 0.04). For every hour increase in the interventions focusing on care recipient behavior, there was an associated decrease in carers' complicated grief (PE = -2.91, P = 0.04).

CONCLUSION

There is little evidence upon which to base practice with regard to interventions to reduce any aspects of grief. Findings suggest that different pre-death interventions might be warranted depending upon a family carer's unique clinical presentation and combination of risk factors.Cognitive skills training provided while the care recipient is alive may positively impact normal and complicated grief following the death of the care recipient. When the cognitive skills training is provided in conjunction with behaviorally oriented interventions that improve the wellbeing of the carer and care recipient, carers' complicated grief symptoms may be reduced.
