The effect of long-term life dissatisfaction on health-related quality of life among general population subjects.

The aim of this population-based study (n = 329) was to explore how long-term life dissatisfaction (LS burden) and concurrent life dissatisfaction are associated with the concurrent health-related quality of life (HRQL) (RAND-36), and how long-term life dissatisfaction predicts HRQL in the general population. The sum of the life satisfaction scores in 1998, 1999, 2001 (LS burden) and the concurrent life satisfaction score (LS) in 2005 were used to categorize the study participants into satisfied, intermediate and dissatisfied groups. Differences in RAND-36 dimensions in 2005 were investigated with respect to the LS burden and concurrent life dissatisfaction. The predictive power of the LS burden for HRQL dimensions was assessed with logistic regression models. Both a high LS burden and concurrent life dissatisfaction were strongly associated with HRQL and were risk factors for poor HRQL, regardless of its dimensions. The LS burden predicted all of the RAND-36 dimensions, except for physical functioning. Screening of life dissatisfaction can be used to identify service users whose HRQL should be further investigated. Assessment of HRQL provides information on the domains and factors that require mental health nursing intervention. This knowledge could assist mental health nurses in both the alleviation of disease consequences and promotion of well-being of service users.
