Abstract
- Purpose: The international wellbeing index (IWI) consists of two scales, the personal (PWI) and national (NWI) wellbeing indices. The community wellbeing index (CWI) is a new measure of the individual's level of satisfaction with the local place of residence. The main goal of this paper is to validate the CWI in a sample of older adults.<br />Methods: The IWI was satisfactorily applied to survey the global quality of life of a community sample of 1,106 people aged 60 years and over residing in Spain. The CWI psychometric properties were studied using Rasch analysis. Classic psychometric parameters were also analyzed.<br />Results: Tests of unidimensionality, and exploratory and confirmatory factor analyses, revealed the presence of three subscales: community services, community attachment, and physical and social environment. To achieve adequate model fit of the three subscales to the Rasch model, one item (distribution of wealth) of the initial 11 was removed and item response categories were rescored. The person separation index was 0.82-0.85, indicating a good reliability. All items were free from gender bias. The three subscales displayed satisfactory convergent validity with the PWI and NWI and were able to discriminate between groups with high and low satisfaction with local place of residence.<br />Conclusion: The CWI, made up of three subscales, is a valid and reliable measure of subjective wellbeing related to the community as assessed by older adults. Further research with this promising measure should focus on cross-national comparisons.
