Exploratory examination of the scale structure of the Moorong Self-Efficacy Scale: Application of Rasch Measurement Theory

This study explores the Moorong Self-Efficacy Scale (MSES) using a method called Rasch Measurement (RM) to see if it consistently and accurately measures self-efficacy in people with spinal cord injuries. The researchers looked at how well the scale's items and rating system work, and whether the scale measures a single, clear concept of self-efficacy. The study found that some adjustments to the MSES could improve its accuracy and usefulness for measuring self-efficacy in this population, but further research with larger groups is needed.

• 1
  The original 16-item MSES had issues with item misfit, infrequent category endorsement, and category step disorder.
• 2
  Removing two items (personal hygiene, bowel accidents) and reorganizing the rating scale improved the scale's fit and reliability.
• 3
  The revised 14-item scale showed evidence of unidimensionality, although there was a possible second dimension related to social interactions and personal achievements.
