title: Rasch analysis of the General Self-Efficacy Scale in spinal cord injury.
abstract: This study examined the psychometric properties of the General Self-Efficacy Scale by applying Rasch analysis to data from 102 persons with spinal cord injury. Our results suggest that the General Self-Efficacy Scale is a psychometrically robust instrument suitable for application in a spinal cord injury population. The General Self-Efficacy Scale shows an overall fit to the Rasch model (χ(2) = 15.5, df = 20, p = .75), high reliability (rp = 0.92), ordered response scale structure, and no item bias by gender, age, education, and lesion levels. However, the analyses indicate a ceiling effect and potential to enhance the differentiation of the General Self-Efficacy Scale across self-efficacy levels.
