| Annotation | Differences across countries make it unlikely that researchers can develop a single social resource scale that would have item equivalence in multiple countries. This article examines data quality, reliability and construct validity of the Older Americans Resources and Services (OARS) social resources scale in six European countries (the Netherlands, Luxembourg, Italy, Austria, the UK and Sweden). A questionnaire was administered through face-to-face interviews in five countries, and postal interview in the sixth, to representative populations of adults aged 50-90 (n=12178) living independently. This article examines missing values and distribution of items in OARS, and consistency of skew and kurtosis across countries. The authors performed item-total correlations and non-confirmatory factor analyses to test a 3-factor model obtained in previous US and Spanish analyses. Crohnbach's alpha determined the reliability of the factors. A relatively large proportion of missing data for one item (have someone who would help you) was observed. All items correlated with a score equal to or greater than 0.20. Although the continuity factor analyses generally supported the acceptability of the 3-factor structure of the European data, the reliability of two dimensions (dependability and affective) was unacceptably low.
