Psychometric qualities of a scale to measure the apprentice’s sense of personal effectiveness in a work situation
This article is in line with research on self-efficacy (Bandura, 2007). It reports on a study aimed at constructing and validating a new scale for measuring apprentice professional self-efficacy. The assessment of its validity and reliability is based on a sample of 110 apprentices from the Martinican Regional Apprenticeship University. The results reveal that the scale has acceptable internal consistency and an exploratory factor analysis highlights four factors consistent with the postulated conceptual framework (alpha = 0.90). The construction of the apprentice professional self-efficacy scale followed a seven-step survey scale design process based on DeVellis (2003), namely: clearly define the construct, develop items, define response format, conduct expert validation, conduct pretest, conduct pilot testing: check for appropriate item reliability and convergent/discriminant validity.
