This study aimed to determine the prevalence and sources of stress among Thai medical students. The questionnaires,which consisted of the Thai Stress Test (TST) and questions asking about sources of stress, were sent to all medical students in the Faculty of Medicine, Ramathibodi Hospital, Thailand. A total of 686 students participated. The results showed that about 61.4% of students had some degree of stress. Seventeen students (2.4%) reported a high level of stress. The prevalence of stress is highest among third-year medical students. Academic problems were found to be a major cause of stress among all students. The most prevalent source of academic stress was the test/exam. Other sources of stress in medical school and their relationships are also discussed. The findings can help medical teachers understand more about stress among their students and guide the way to improvement in an academic context, which is important for student achievement.

Background: Most depression screening tools in Thailand are lengthy. The long process makes them impractical for routine use in primary care. This study aims to examine the reliability and validity of a Thai version Patient Health Questionnaire (PHQ-9) as a screening tool for major depression in primary care patients.

Aims: Because of the high patient load in Thailand, we need a practical measurement to help primary physicians detect depression. This study aimed to examine the reliability and validity of the Thai version of the World Health Organization-Five WellBeing Index (WHO-5-T), which is short and easy to use as a screening tool for major depression in primary care patients. Methods: The English version of the WHO-FiveWell-Being Index was translated into Thai. Backtranslations, cross-cultural adaptation and field testing of the pre-final version with final adjustments were performed accordingly. The WHO-5-T was administered randomly to 300 patients in our primary care clinic. Then the patients were further assessed using the Mini International Neuropsychiatric Interview and the Hamilton Rating Scale for Depression as the gold standard of diagnosis and symptom severity, respectively. Results: Conclusions:The Thai version of the WHO-Five WellBeing Index was found to be a reliable and valid self-assessment to screen for major depression in primary care setting at a cut-off point of <12.

Purpose The Yale–Brown Obsessive Compulsive Scale (Y-BOCS) is regarded as the most acceptable tool for measuring obsessive–compulsive disorder symptom severity. Recently, the Yale–Brown Obsessive Compulsive Scale – Second Edition (Y-BOCS-II) was developed for better measurement. The study reported here aimed to evaluate the psychometric properties of the Thai version of the Yale–Brown Obsessive Compulsive Scale – Second Edition (Y-BOCS-II-T). Patients and methods The original version of the Y-BOCS-II was translated into Thai, which involved forward translation, synthesis of the translation, and back translation. Modification and cross-cultural adaptation were completed accordingly. The developed Y-BOCS-II-T, together with the Hamilton Rating Scale for Depression, was administered to 41 patients who had a primary diagnosis of obsessive–compulsive disorder. The patients then completed the Pictorial Thai Quality of Life instrument and Patient Health Questionnaire. Lastly, the Global Assessment of Functioning (GAF) and the Clinical Global Impression – Severity Scale (CGI-S) of all patients were blindly rated by another experienced psychiatrist who was not the interviewer. Results The mean total score of the Yale–Brown Obsessive Compulsive Scale – Second Edition – Severity Scale (Y-BOCS-II-SS) and the Yale–Brown Obsessive Compulsive Scale – Second Edition – Symptom Checklist (Y-BOCS-II-SC) were 18.44 (standard deviation =10.51) and 15.85 (standard deviation =9.58), respectively. The Y-BOCS-II-T had satisfactory internal consistency (Cronbach’s alpha =0.94 for the Severity Scale, and Kuder–Richardson Formula 20 =0.90 for the Symptom Checklist). Inter-rater reliability was excellent for both the Y-BOCS-II-SS and Y-BOCS-II-SC. Factor analysis of Y-BOCS-II-SS items revealed a two-factor component associated with obsession and compulsion. The Y-BOCS-II-SS correlated highly with the CGI-S and GAF ( r =0.75 and −0.76, respectively), but the Y-BOCS-II-SC correlated moderately ( r =0.42 for CGI-S; r =−0.39 for GAF). The Y-BOCS-II-SS and Y-BOCS-II-SC slightly to moderately correlated with the Hamilton Rating Scale for Depression, Patient Health Questionnaire, and Pictorial Thai Quality of Life, which might indicate the comorbidity depression and its effect on quality of life. Conclusion The Y-BOCS-II-T is a psychometrically reliable and valid measure for the assessment of both severity and characteristics of obsessive–compulsive symptoms in Thai clinical samples.
