title: General perceived self-efficacy: validation analysis in Greek cancer patients.
abstract: OBJECTIVE
  The present study aims to validate the General Perceived Self-efficacy Scale (GSE) in Greek cancer patients.
  
  
  METHODS
  The scale was administered twice, with a 3-day interval, to 99 advanced cancer patients. The patients also completed the Anxiety Subscale from the Greek Hospital Depression and Anxiety Scale.
  
  
  RESULTS
  Factor analyses identified a one-factor solution, explaining 74.6% of the variance. The Greek version of the GSE had a Cronbach's alpha of 0.927. Validity as performed using known-group analysis showed good results. Satisfactory construct validity was supported by the correlation analysis between the GSE and anxiety (r = -0.507, p < 0.0005). Interitem correlations was also satisfactory at p < 0.0005.
  
  
  CONCLUSIONS
  These psychometric properties of the Greek version of the GSE showed that it is a valid and reliable measured when administered to cancer patients.
