Abstract

The prevalence of stress is increasing worldwide. Stressful working environments and high expectations in medical practice put doctors at high risk of adjustment disorder especially among housemen in Malaysia. It is important to assess adjustment disorder in the housemen for early intervention to reduce the psychological distress. There are few measures to assessadjustment disorder, which include the more recent scale named Adjustment Disorder New Module-20 (ADNM-20) questionnaire. However, there is no available study on Malay version ofADNM-20. The goal of present study was to validate the Malay version of the ADNM-20 for use in the Malaysian context. Method The study was cross-sectional in design and consisted of 140 housemen in the teaching hospital. Participants were given Malay version of the ADNM-20, Hospital Anxiety and Depression Scale (HADS) and structure interview to assess adjustment disorder. Result The Malay version of ADNM-20 exhibited good internal consistency (Cronbach’s alpha=0.97) and good concurrent validity. Explorative factor analysis support two factors and six- factor solution. Item 16 on the scale does not correlate with the other items. Receiver Operating Characteristics (ROC) analysis demonstrated a cut-off value of 48 on the Malay version of the ADNM-20 to identify probable adjustment disorder in the housemen. This score had a sensitivity of 100% and specificity of 96%. Conclusion The Malay version of the ADNM-20 is a good tool with good validity and reliability for assessing adjustment disorder. Additionally, it is relatively short and easy to administer, making it useful in the clinical setting.
