A Dutch translation of the Self-Efficacy for Rehabilitation Outcome Scale (SER): a first impression on reliability and validity

Self-efficacy is a relevant factor during rehabilitation after total hip or knee arthroplasty. Research was done into the reliability and validity of a Dutch translation of the Self-Efficacy for Rehabilitation Outcome Scale (SER). One hundred and forty-one persons filled in the SER questionnaire and the Self-Efficacy Expectation Scale (SES) as a control scale. Research was done into reliability and into construct- and criterion-related validity. Factor analysis yielded two factors. Pearson's correlation between the two factors was 0.61 (P <0.01). To assess criterion-related validity, the Pearson's correlation coefficient was calculated between the sum score of the SER and the SES. The scales had a correlation of 0.62 (P
