OBJECTIVES: To translate the Minnesota Nicotine Withdrawal Scale (MNWS) to Malay language and evaluate the psychometric properties of translated version. METHODS: A cross sectional design was used to elaborate the study data. Adult smokers who attend the Quit Smoking Clinic in Penang General Hospital at Penang State, Malaysia were included in the study. The original scale was translated into Malay version following the standard guidelines proposed for translation studies. The reliability and validity of Malay version scale was evaluated based on the data collected from 133 participants. Cronbach’s alpha coefficient was calculated to assess the reliability. In order to assess the validity of the scale, Factor analysis and convergent validity was employed to validate the psychometric properties of the scale. RESULTS: The Malay version of MNWS has an excellent reliability with an internal consistency was measured by total Cronbach’s alpha of 0.91. The test-retest reliability for the scale were presented an excellent reliability and stability of the translated scale with Spearman’s Rank Correlation Coefficient, r = 0.876 (P <0.001). In addition, There was a significant positive correlation between carbon monoxide level, FTND total score and number of cigarettes smoked per day with MNWS total score (r = 0.72, r = 0.68 and r = 0.68, P<0.001; respectively). A principal components analysis with orthogonal rotation yielded a uni-dimensional model which includes all the items of MNWS. CONCLUSIONS: The Malay version of MNWS is reliable and a valid measure for withdrawal symptoms as well as the smoking urge and it is applicable for clinical practice and research study.
