Insomnia and well-being.

Abstract

Most Americans have occasional problems with insomnia. The relationship of insomnia to illness is well known. However, insomnia may also relate to lower levels of well-being. Although there are various definitions of well-being, one of the most clearly articulated and comprehensive models identifies 2 overarching constructs, psychological well-being and subjective well-being. The purpose in the present study was to assess the relationship between insomnia symptoms and the dimensions of psychological and subjective well-being, adjusting for the potential confound of comorbid physical and psychological illness. The data for the present study came from the National Survey of Midlife Development in the United States, a survey of community-dwelling adults. After adjustment for demographic characteristics and a wide range of chronic mental and physical health conditions, insomnia symptoms were found to have a significant relationship with both psychological and subjective well-being but a stronger relationship to subjective well-being. These data suggest that insomnia symptoms have a stronger relationship to enjoying life than to the perception that one has a meaningful life.
