The aim of the study is to evaluate the psychometric properties of the Bahasa Melayu version of the Taqwa (piety) questionnaire, used for the measurement of behaviour of Drug Dependency Syndrome (DDS), in Malay patients. A sample of 98 males with a psychiatric diagnosis (DSM-IV-R) as the DDS was randomly selected from Kajang Khafidz Polyclinic Kuala Lumpur, Malaysia. After receiving their agreement to attend the study, they completed the Taqwa (piety) questionnaire. The reliability was assessed by determining the Cronbach's [Formula: see text] to measure the consistency of related questions for all four dimensions (subscales), including individual, social, cognitional, and emotional Taqwa behaviour. In the next step to evaluate the composite reliability, convergent, and discrimination validity, a measurement model was determined via Conformity Factor Analysis (CFA) based on Partial List Square method (Smart- PLS Ver: 2M3). The reliability of four dimensions of the questionnaire was acceptable ([Formula: see text] correlated to each other. However, according to the CFA method, the items with low loading factor (<0.5) were excluded from each dimension. Item 24 and 35 that were related to individual Taqwa, and item 35 that belonged to emotional Taqwa were excluded from the analysis. The composite reliability and convergent, and discrimination validity were satisfied in all conformity factor loading that exceeded 0/05. The psychometric properties of the Taqwa questionnaire are acceptable, and the scale is a good instrument for assessing the Islamic attitude, beliefs, and behaviour of the Bahasa Melayu DDS patients.

Background: Chronic patients are at greater risk for a psychiatric problem than the normal population; yet, the increased rate of mental disorder among one chronic patient compared to another chronic patient is uncertain. We aimed to assess the rate of mental disorder among people with heroin dependence and diabetes mellitus in comparison with the healthy population. Methods: This cross-sectional study was carried out in Kuala Lumpur, Malaysia in 2017-2020.   The study consisted of 648 participants including heroin dependence patients, diabetes mellitus patients, and healthy population. The GHQ-28 and SCL-90-R scales were used to assess mental disorder among the study populations. Results: The current study revealed the rate of mental disorder among heroin dependence patients, diabetes mellitus patients, and healthy population respectively at 52.1%, 49.5%, and 23.2% using SCL-90-R and GHQ-28. The rate of mental disorder in both heroin dependent (OR 95%= 3.59: 2.37-5.44) and diabetic groups (OR 95%=3.25: 2.14-4.92) were significantly more than the healthy population; however, the odds ratio of mental disorder was not significantly different between heroin dependent and diabetic groups. Furthermore, the results revealed an acceptable agreement between SCL-90-R and GHQ-28 to detect mental disorders (Kappa=0.60; P<0.001). Conclusion: People with diabetes mellitus and heroin dependence have significantly poorer mental health than healthy people in Malaysia have. Furthermore, the equivalent rate of mental disorder among such patients suggests that heroin dependence patients are not more distressed than diabetes mellitus patients are. However, further comparative studies are needed to prove these findings.
