Objective: This study is an attempt to produce an abbreviated Malay version of Weight and Lifestyle Inventory (MWALI), as well as to examine the psychometric properties of the eating behavior which formed part of MWALI. Methods: The MWALI was translated ‘forward–backward’ from English to Malay and then administered to 135 adolescents. The factor construct of the 24-item eating behavior and the relationships between factor scores and demographic profile, dysphoria, global self-esteem and body mass index (BMI) were examined. Results: The exploratory factor analysis yielded five factors: Negative Emotion, Poor Impulse Control, Social Cues, Snacking and Early Meals in relation to over-eating. All the factors were significantly and positively correlated with BMI. Internal consistency and test-retest reliability of the eating behavior were satisfactory. Conclusion: MWALI is appropriate for assessing eating behavior among overweight and obese adolescents in the primary care setting in Malaysia.
