Abstract

Goals of work

The present study aims to validate the General Perceived Self-efficacy Scale (GSE) in Greek cancer patients.

Materials and 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.

Main 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.
