Estratégias de coping entre cuidadores de pessoas com doença de Alzheimer: uma revisão sistemática

Autoria SCIMAGO INSTITUTIONS RANKINGS

Resumo

Introdução

Cuidadores de pessoas com doença de Alzheimer relatam mais estresse, sobrecarga e depressão em comparação com cuidadores de pessoas com outras patologias, especialmente quando os sintomas neuropsiquiátricos são proeminentes. Estratégias adequadas de enfrentamento podem modificar o impacto de situações estressantes e aumentar a qualidade de vida do cuidador.

Objetivo

Revisar sistematicamente as diferentes estratégias de enfrentamento utilizadas pelos cuidadores para lidar com sintomas neuropsiquiátricos.

Método

Foi realizada busca eletrônica em artigos publicados entre janeiro de 2005 e julho de 2017 nos bancos de dados MEDLINE (PubMed), SciELO, Web of Knowledge Cross Search (Thomson Scientific/ISI Web Services) e PsycINFO. Os termos utilizados foram coping, caregivers, strategy, onset, adaptation, family, behavior, dementia and Alzheimer. Os artigos avaliados foram categorizados em estratégias de enfrentamento focadas na resolução do problema, na emoção e estratégias disfuncionais.

Resultados

Foram encontrados 2.277 artigos. Após aplicação dos critérios de exclusão, foram incluídos 24 artigos. A estratégia de enfrentamento mais utilizada foi a focada na emoção. O uso desta estratégia associada a religião e espiritualidade pode reduzir sintomas de depressão e ansiedade dos cuidadores. As estratégias de enfrentamento focadas na resolução do problema utilizaram principalmente intervenções baseadas no enfrentamento ativo. A resolução de problemas reduz o impacto dos estressores psicológicos agudos sobre a atividade procoagulante. As estratégias disfuncionais estavam associadas ao aumento da sobrecarga dos cuidadores.

Conclusão

Os estudos mostraram que o desenvolvimento e uso de estratégias de enfrentamento pode aliviar sintomas depressivos, ansiosos e sobrecarga do cuidador. No entanto, ainda são necessários estudos longitudinais que descrevam claramente o tipo de estratégia de enfrentamento utilizada em relação aos desfechos das pesquisas.

Task focused on the highest reported coping strategy. Emotion-focused and avoidance-focused coping each showed significant proportional effects on burden.
Raggi, et al.²⁸	N = 73 AD primary caregiver	Cross-sectional	PwAD: CDR, GDS, ADL, NPI, CIRS Caregivers: CBI, NPI	Determine the severity of caregiver burden in relation to cognitive, behavioral, functional, mood, mobility, and comorbidity status of patients; investigate coping strategies for caregivers according to their distress; and assess psychosocial and medical variables related to caregiver burden.	Problem-focused coping strategies.	The severity of caregiver distress was correlated with specific coping strategies, such as seeking for social support, using avoidance behaviors and focusing on problems.
Li, et al.⁷	N = 260 family carers of PwD	Randomized	START HADS BRCOPE	Test the hypothesis that increased emotion-focused coping at 4 months would mediate the effects of the START intervention in reducing psychological morbidity symptoms at 8 months; and test whether this mechanism was moderated by baseline morbidity.	Emotion-focused coping strategies. Eight-session START intervention. The intervention was based on the stress appraisal and coping model. Treatment-as-usual.	The strategies brought psychological benefits to morbidity in different mechanisms of action. The more psychologically distressed caregivers increased their emotion-focused coping strategy and did not diminish their dysfunctional coping, while others improved burnout through this mechanism.
Williams et al.²⁷	N = 13 caregivers of people with either stroke (n = 5) or dementia (n = 8)	Cross-sectional	Semi-structured interviews	Explore coping strategies that caregivers use to care for the elderly.	Problem-focused coping strategies. Use of photographs that caregivers took exemplifying their caregiving experiences to elicit their description of how they made sense of caregiving.	Caregivers adopted active and information seeking techniques to deal with current problems and to increase their sense of control, but avoidant techniques when considering future logistics of caregiving and when feeling helpless due to the burden they faced.
Sun & Hodge²²	N = 209 Latino caregivers included with parents in USA	Cross-sectional	REACH MMSE IADL ADL ZBI CES-D	Examine the effects of spirituality and religion on depression in a sample of Latino AD caregivers.	Emotion-focused coping strategies.

Problem-focused coping strategies.	Caregiver coping strategies are associated with slower dementia progression.
Livingston et al.²⁵	N = 260 carers of family members with dementia	Cross-sectional	HADS QOL-AD CTS2 NPI CDR BRCOPE START	Assess whether a manual-based coping strategy compared with treatment as usual reduces depression and anxiety symptoms in carers of family members with dementia.	Emotion-focused coping strategies. A manual-based coping strategy program can be delivered by graduate psychologists without clinical training.	Mean total scores on HADS were lower in the intervention group than in the treatment as usual group over the 8-month evaluation period.

Two coping strategies: task-focused, emotion-focused	Coping strategies are associated with BPS regardless of patient characteristics. Interventions to reduce BPS should focus on which psychological coping strategies caregivers use.
Bruvik et al.³¹	N = 230	Randomized	RSS NPI PSMS IADL MMSE GDS	Investigate the association between coping, care of local extent and burden of family caregivers of PwAD.

Emotion-focused coping strategies. Five saliva samples were collected daily (at awakening, 9am, 12pm, 5pm, and 9pm) for two straight days.	The RCOPE by RMBPC interaction was significant. Among caregivers who showed higher RMBPC scores, higher combined and positive (but not negative) RCOPE scores were unexpectedly associated with increasingly flatter cortisol slopes.
García-Alberca et al.¹²	N = 80 patients and caregivers	Cross-sectional	Patients: MMSE, B-ADL, GDTS, NPI Caregivers: ZBI, BDI, STAI, CSI	Investigate the relationship between anxiety and depression, and engagement and disengagement coping strategies, in caregivers of PwAD in an epidemiological population.

Secondary analyses were conducted on individual health behaviors subsumed in the broader index.	Emotion-focused coping strategies. Caregivers were asked to answer questions about religious coping strategies, religion and their own health.	Findings revealed that negative religious coping was significantly associated with increased cumulative health risk. Positive religious coping was predictive of decreased cumulative health risk among Latina caregivers but not among Caucasians. Negative religious coping was significantly associated with both an increased likelihood for weight gain and increased dietary restriction. Positive religious coping was associated with decreased likelihood for weight gain in Latinas.
