Self-efficacy and spinal cord injury: Psychometric properties of a new scale

Objective: To determine the psychometric properties of the Moorong Self-Efficacy Scale (MSES). Design: Descriptive, correlational study. Participants: Persons with spinal cord injury. Main Outcome Measure: The MSES is a 16-item scale rating confidence in performing everyday activities on a 7-point Likert scale. Procedure: The MSES and other validating instruments were administered to outpatients (n = 36) on 2 occasions; postacute patients undergoing rehabilitation (n = 31) at 1, 3, and 6 months after mobilization; and a community sample (n = 108) by mail. Results: The MSES is internally consistent, responsive, and stable, demonstrating good concurrent, convergent, and discriminant construct validity. Principal-components analysis extracted two factors, labeled Daily Activities and Social Functioning. Conclusions: Strong psychometric properties of the MSES make it a valuable clinical and research tool.
