ABSTRACT
Este estudio evalúa la validez y confiabilidad del Índice de Capacidad para el Trabajo (ICT) en Argentina. El instrumento se aplicó a 100 trabajadores, agentes de Atención Primaria de la Salud del Partido de General Pueyrredón. En la validez del constructo se investigó la estructura dimensional por medio de análisis factorial exploratorio, a partir de una matriz policórica y un análisis paralelo para la obtención del número de factores. En la validación correlacional se estimó la correlación de Spearman entre el ICT y las dimensiones del Cuestionario de Salud SF-36. La evaluación de confiabilidad se midió a través del estimador Alfa de Cronbach. El resultado de la consistencia interna de la escala fue 0,80, indicando una fiabilidad aceptable. La puntuación de ICT arrojó como resultado: moderado 12%, bueno 50% y óptimo 38%. En el proceso de validación se identificó una estructura de tres dimensiones que explica el 66% de la variación total de los datos a través de los componentes principales. Los supuestos teóricos de la validez del constructo confirmaron la correlación directa y significativa con las puntuaciones del ICT y las dimensiones de evaluación del estado de salud, siendo el mayor valor función física (0,478) y menor la dimensión dolor (-0,218). Se concluyó que el ICT, traducido y adaptado al español, mostró propiedades psicométricas adecuadas pudiendo ser utilizada en estudios de asociación entre aspectos de trabajo y su impacto en la salud.
This study evaluates the validity and reliability of the Work Ability Index (WAI) in Argentina. An instrument was applied to 100 workers, all agents of Primary Health Care in the county of General Pueyrredón. In the construct validity, the dimensional structure was studied by means of exploratory factor analysis, based on a polychoric matrix and parallel analysis to obtain the number of factors. In the correlation validation, the Spearman correlation was estimated between the WAI and the dimensions of the 36-Item Short Form Health Survey (SF-36). The reliability assessment was measured by Cronbach's alpha estimate. The result of the internal consistency of the scale was 0.80, indicating acceptable reliability. The WAI score yielded the following results: 12% moderate, 50% good and 38% optimal. In the validation process, a three-dimensional structure was identified which accounts for 66% of the total variance of the data through the main components. The theoretical assumptions of the construct validity confirmed the direct and significant correlation between WAI scores and the dimensions of health status assessment, with the highest value in the physical functioning dimension (0.478) and the lowest in the bodily pain dimension (-0.218). It was concluded that the WAI, translated and adapted into Spanish, showed adequate psychometric properties and can therefore be used in association studies between aspects of work and their impact on health.

The main focus of this study was the effect of chronic disease (hypertension, diabetes mellitus, heart disease, lung disease, cancer, and arthropathy) on the functional status (activities of daily living - ADL, instrumental activities of daily living - IADL) among the elderly, controlling for age, gender, living arrangements, education, and comorbidity. The analysis was based on information provided by the SABE Project, from the city of São Paulo, Brazil, including individuals 60 years of age and over (n = 1,769), from January 2000 to March 2001. A multinomial logistic regression model was used. Compared to the absence of dependency category, heart disease (OR = 1.82), arthropathy (OR = 1.59), lung disease (OR = 1.50), and hypertension (OR = 1.39) were the main diseases that affected the IADL dependency category. Lung disease (OR = 2.58), arthropathy (OR = 2.27), hypertension (OR = 2.13), and heart disease (OR = 2.10) had important impact on the IADL and ADL dependency categories. The results were statistically significant (p < 0.05).
