The measurement of self-efficacy in persons with spinal cord injury: psychometric validation of the moorong self-efficacy scale.

Abstract

The factorial and concurrent validity of the Moorong Self-Efficacy Scale (MSES) was examined using a sample of Americans with spinal cord injury. One hundred sixty-two participants were recruited with the assistance of the Florida Brain and Spinal Cord Injury Program and the Florida Spinal Cord Injury Resource Centre. Mean age of participants was 45.8 years (SD = 13.4), and 68.5% were men. The participants completed a survey containing a demographic questionnaire, the MSES, the Satisfaction with Life Scale (SWLS), the Personal Resources Questionnaire--2000 (PRQ-2000), and the Centre for Epidemiologic Studies Depression Scale--10 item version (CES-D-10). Factor analysis yielded two factors (Interpersonal Self-Efficacy and Instrumental Self-Efficacy) similar to the original MSES. In addition, the MSES factors and total score in the present study were significantly correlated in the predicted directions with specified psychosocial variables, as well as hours of paid employment. The results of this study support the factorial and concurrent validity of the MSES as a self-efficacy measure in Americans with spinal cord injury.
