Despite the concerns about professionalism among youth work practitioners in Malaysia, valid and reliable instruments to measure the construct are lacking. This article reviews the psychometric development and initial exploration of a professionalism measure applicable for use with direct-service youth work practitioners. Results were based on a sampling of 813 government and non-government youth work practitioners throughout Malaysia. Exploratory factor analysis resulted in a 6-factor solution that was used as the basis for the subscales of the instrument. Comparison of means tests indicated higher mean scores according to academic qualification, age, income, gender, marital status and certification and years of involvement in youth work. Limitations and recommendations for further development of the professionalism scale are discussed.
