Diseño y validación de una escala para la medición de la dedicación al cuidado en personas cuidadoras de mayores dependientes (DeCuida)

OBJECTIVE: To develop and validate a scale to measure caregiving dedication regarding activities of daily living in caregivers of dependent older people. DESIGN: Cross-sectional study. LOCATION: Primary Health Care (Andalusia, Spain). PARTICIPANTS: a probabilistic sample of 200 caregivers of older relatives from Córdoba, Spain. MAIN MEASUREMENTS: Content validation by experts, construct validity (by exploratory factor analysis), divergent validity and reliability (internal consistency, test-retest reliability and inter-observers reliability). RESULTS: Cronbach's alpha was 0.86. Intraclass Correlation Coefficient was 0.96 for test-retest reliability and 0.88 for inter-observers reliability. When the sample was divided in two groups according to perceived burden level (presence and absence), the perceived burden was significantly different in each group (P=.001). The factor analysis revealed one only factor that explained 64% of the variance. CONCLUSIONS: The scale allows a suitable measure of caregiving dedication regarding activities of daily living in caregivers of older people, because this scale allows a quickly, easy administration, is well accepted by caregivers, has acceptable psychometric results and includes the frequency of caregiving, the kind of attended need and the dependence level in each need.
