Healthy life, social interaction and disability

This paper aims at analysing two relevant dimensions of well-being: living a healthy life and social interaction. A link between the two dimensions of well-being has been highlighted in the literature. The model assumes that both these concepts, i.e. social interaction and healthy life, are latent and manifest themselves through a number of indicators. The indicators adopted are those available in the 2011 ISTAT survey on social inclusion of people with disability in Italy by comparing the well-being attainments with respect to the different levels of functional limitations. In this paper the available indicators are used simultaneously to study the level of social interaction and health through a multiple indicators multiple causes model. This allows us to deal directly with endogeneity issues. Results show that women have a lower achievement in social interaction and in health. Moreover, differences occur in the effect of the observable exogenous variables included in the model with a larger negative effect of ageing for women on their health status and a higher negative effect of ageing for men on social interaction. Education plays a significant role only for women for the healthy life dimension. Finally, the latent variable on social interaction has been found to positively affect, consistently with the literature, the health dimension.
