title: Validating and norming of the Greek SF-36 Health Survey.
abstract: The main objective of this study was to validate the Greek SF-36 Health Survey and to provide general population normative data. The survey was administered to a stratified representative sample (n = 1426) of the general population residing in the broader Athens area and the response rate was 70.6%. Statistical analysis, according to documented procedures developed within the IQOLA Project, was performed. The missing value rate was very low, ranging from 0.1 to 1.3% at the item level. Multitrait scaling analysis confirmed the hypothesized scale structure of the SF-36. Cronbach's alpha coefficient met the criterion (>0.70) for group analysis in all eight scales. Known group comparisons yielded consistent support of construct validity of the SF-36. Significant statistical differences in mean scores were observed in relation to demographic and social characteristics such as gender, age, education and marital status.
