OBJECTIVE: Psychiatric deinstitutionalization resulted in greater involvement of families in daily care of patients. Family caregivers burden has been described by international researches. In Brazil very few studies investigated family burden with validated scales, perhaps due to the restrict availability of scales to measure this construct. The present study examined the reliability of the Brazilian version of the Family Burden Interview Schedule. METHOD: Scale reliability was assessed through its internal consistency and temporal stability. A sample of 243 family caregivers of psychiatric patients attending public outpatient services were interviewed with the scale. Socio-demographic data were collected with a standardized form. A sub-sample of 42 relatives participated in a re-test, after 3 weeks, for assessment of the scale temporal stability. RESULTS: Cronbach alpha coefficients ranged from 0.58 to 0.90 for global and domains scores. Pearson correlation coefficients and intra-class correlation coefficients for test and retest ranged from 0.54 to 0.90. DISCUSSION: Results for internal consistency were similar to the original scale. Four subscales presented alpha coefficients superior to the original ones. The temporal stability cannot be compared because this analysis was not performed for the original scale. CONCLUSION: The Brazilian version of the scale had good psychometric properties of temporal stability and internal consistency.OBJETIVO: A desinstitucionalização psiquiátrica resultou em maior envolvimento das famílias nos cuidados diários dos pacientes. Pesquisas internacionais constataram a sobrecarga dos familiares, mas, no Brasil, poucas pesquisas a investigaram utilizando escalas validadas, talvez devido à carência de instrumentos de medida deste construto. Este estudo avaliou a confiabilidade da versão brasileira da escala Family Burden Interview Schedule. MÉTODO: Avaliou-se a confiabilidade, em termos da consistência interna e estabilidade temporal. Foram entrevistados 243 familiares cuidadores de pacientes psiquiátricos de serviços públicos de saúde mental. Os dados sociodemográficos foram obtidos por questionário padronizado. Uma subamostra de 42 familiares foi entrevistada novamente, após três semanas, para avaliação da estabilidade temporal teste-reteste. RESULTADOS: Os coeficientes alfa de Cronbach para os escores globais e domínios variaram de 0,58 a 0,90. Os coeficientes de correlação de Pearson e de correlação intraclasse para o te
