Abstract

Purpose of study: To gain Swedish norm value for the Life Satisfaction Index-A (LSI-A) in a population 60-93+ years old stratified for sex and age and to relate these norm values with respect to number of chronic diseases and functional impairment.

Materials and methods: The study population included a random sample of 2656 men (45.7%) and 3159 (54.3%) women from the longitudinal national studies' "Good Aging in Skåne" (GÅS) and SNAC-B, both part of the Swedish National Study on Aging and Care (SNAC). Data on Neugartens Life Satisfaction Index-A (LSI-A), medical history, activities of daily life (ADL) and socio-demographics were collected through structured interviews and questionnaires.

Results: Men scored significantly higher than women; 28.5, sd=6.9, and 27.3, sd=6.6, respectively, out of maximum 40 points. For both genders the scores decreased with age, mean score 6.0 points, lower for men and 7.1 points lower for women between 60 and 93+ years. The highest score was noted for healthy individuals where both men and women scored 29.5 points, sd=6.2. Increased number of chronic diseases and dependency in ADLs were associated with lower LS.

Conclusion: Norm values here presented may facilitate assessments and evaluation of life satisfaction in the general elder population and as reference values to clinical trials. Female sex, rising age, morbidity and impaired functional ability were all associated with impaired LS.
