Reliability and Validity of the Self-Efficacy for Exercise in Epilepsy and the Outcome Expectations for Exercise in Epilepsy Scales

Purpose: The purpose of this study was to test the psychometric properties of the revised Self-Efficacy for Exercise With Epilepsy (SEE-E) and Outcome Expectations for Exercise with Epilepsy (OEE-E) when used with people with epilepsy. Methods: The SEE-E and OEE-E were given in face-to-face interviews to 26 persons with epilepsy in an epilepsy clinic. Results: There was some evidence of validity based on Rasch analysis INFIT and OUTFIT statistics. There was some evidence of reliability for the SEE-E and OEE-E based on person and item separation reliability indexes. Conclusions: These measures can be used to identify persons with epilepsy who have low self-efficacy and outcome expectations for exercise and guide design of interventions to strengthen these expectations and thereby improve exercise behavior.
