Psychometric Properties of a New Achievement Motivation Measure for Arab Postgraduate Students in Malaysia (AMMA)

Abstract

The purpose of this study was to create a theoretically driven instrument of achievement motivation and determine its validity and reliability (AMMA). Exploratory factor analysis (EFA) was used to assess the dimensionality and structural validity and internal consistency of the instrument. The Chronbach Alpha coefficient was also calculated using the test-retest and Split -half  methods.  The Participants included 215 Arab postgraduate students in Malaysia. It was found that this measure has theoretically been effectively supported to measure the achievement motivation by assessing four dimensions (Ambition, Goal setting, Endurance, and Perseverance). Regarding its reliability, The Chronbach Alpha coefficient was 0.85.  The test-retest method yielded a coefficient of 0.83 while the split-half method was at yielded 0.77, indicating that the scale enjoys high reliability.
