RESUMO
INTRODUCTION: In recognition of the role of motivation in drug use treatment, patient motivational screening instruments are needed for strategic planning and treatment. The aims of this study were to evaluate the reliability and validity of the Malay version of the Treatment Motivation Scale, and to compare the motivational levels of patients receiving substance abuse treatment with different modalities (inpatient vs. outpatient). The motivational scale consists of three scales: problem recognition, desire for help and treatment readiness. METHOD: A convenience sample of 102 patients was recruited from four Cure and Care Service Centres in Malaysia. RESULTS: Principal component analysis with varimax rotation supported two-factor solutions for each subscale: problem recognition, desire for help and treatment readiness, which accounted for 63.5%, 62.7% and 49.1% of the variances, respectively. The Cronbach's alpha coefficients were acceptable for the overall measures (24 items: â = 0.89), the problem recognition scale (10 items; â = 0.89), desire for help (6 items; â = 0.64) and treatment readiness scale (8 items; â = 0.60). The results also indicated significant motivational differences for different modalities, with inpatients having significantly higher motivational scores in each scale compared to outpatients. CONCLUSION: The present study pointed towards the favourable psychometric properties of a motivation for treatment scale, which can be a useful instrument for clinical applications of drug use changes and treatment.
