• TITLE: Rasch Rating Scale Analysis of the Arabic Version of the Physical Activity Self-Efficacy Scale for Adolescents: A Social Cognitive Perspective

  KEYWORDS: Rasch Model, Self-Efficacy, Physical Activity, Adolescents

  JOURNAL NAME: Psychology, Vol.6 No.16, December 31, 2015

  ABSTRACT: This study uses the Rasch rating scale analysis within the framework of the social cognitive theory to examine four psychometric properties of the Arabic version of the Physical Activity Self-efficacy Scale for Adolescents (PASESA-Av): 1) item technical quality to evidence content validity; 2) unidimensionality structure to evidence structural validity; 3) rating scale functioning to evidence substantive validity; and 4) person and item separation and reliability. The analyses showed that the PASESA-Av items represented the physical activity self-efficacy trait adequately. The PASESA-Av demonstrated good fit to the Rasch model and formed a unidimensional structure. The PASESA-Av response categories advanced monotonically. The PASESA-Av demonstrated satisfactory person and item separation and reliability.
