Zarit burden interview psychometric indicators applied in older people caregivers of other elderly

Derivar indicadores psicométricos de validade de construto e consistência interna da escala de sobrecarga de cuidadores de Zarit Burden Interview e descrever associações desta com medidas referentes às demandas de cuidado, estratégias de enfrentamento e depressão em cuidadores idosos. Método: estudo descritivo, transversal e correlacional. Cento e vinte e um cuidadores idosos (M= 70,5 ± 7,2 anos, 73% feminino) compuseram uma amostra de conveniência e responderam a um protocolo de pesquisa para levantamento de demandas de cuidado de natureza física e cognitiva, à Zarit Burden Interview (ZBI), ao Inventário de Estratégias de Enfrentamento da Califórnia e à Escala de Depressão Geriátrica (GDS-15). Resultados: a ZBI revelou bons índices de consistência interna e para os três fatores resultantes da análise fatorial, os quais explicaram 44% da variabilidade. A ZBI correlacionou-se positivamente com demandas de cuidado objetivas (p < 0,001), depressão (p = 0,006) e uso de estratégias de enfrentamento disfuncionais (p = 0,0007). Conclusão: a ZBI revela-se interessante para a aplicação a cuidadores idosos e as associações entre altos graus de sobrecarga, enfrentamento disfuncional e depressão apontam um cenário peculiar de vulnerabilidade a que este idoso que cuida de outro idoso pode estar exposto24To derive psychometric indicators of construct validity and internal consistence of the Zarit Burden Interview scale for caregivers, describing associations of the scale with metrics related to care demands, coping strategies and depression in aged caregivers.

ABSTRACT Objective: to derive psychometric indicators of construct validity and internal consistence of the Zarit Burden Interview scale for caregivers, describing associations of the scale with metrics related to care demands, coping strategies and depression in aged caregivers. Method: crosscutting descriptive and correlational study. The convenience sample was composed by a hundred and twenty one senior caregivers (Avg=70.5 ± 7.2 years, 73% women). They answered a questionnaire to check the physical and cognitive demands of care, the Zarit Burden Interview (ZBI), the California Inventory of Coping Strategies and the Geriatric Depression Scale (GDS-15). Results: ZBI showed good internal consistency and also for the three factors emerging from factor analysis, explaining 44% of variability. ZBI is positively related with objective care demands (p < 0.001), depression (p = 0.006) and use of dysfunctional coping strategies (p = 0.0007). Conclusion: ZBI is of interest to be applied to aged caregivers and the association of higher degrees of burden, dysfunctional coping and depression show a vulnerability scenario that may affect to older people taking care of other elderly
