    (The Sri Lanka Medical Association, 2022) Hapangama, A.; Premaratne, I.; Thilaxshan, T.; Gadambanathan, T.; Wickremasinghe, R.
    Background: Despite being the third most prevalent psychiatric disorder, social anxiety disorder remains under-diagnosed due to multiple reasons. Although many screening instruments are available in the English language, to date no instrument has been translated into Tamil. Objective: To translate and validate the Liebowitz Social Anxiety Scale (LSAS-SR) into Tamil among a group of Sri Lankan university students whose mother tongue is Tamil. Method: The process of translation and validation involved standard procedures. DSM- 5 was used as the gold standard to diagnose social anxiety disorder. As part of the psychometric study, test-retest reliability and analysis of items for internal consistency of the instrument were assessed. Results: A cut off of55.5had the optimum sensitivity and specificity for the Tamil version of the LSAS-SR. The Cronbach’s alpha between the avoidance subscaletotal and the fear subscale total was 0.860 while the figures for Cronbach’s alpha between the total score and fear subscale total score and the avoidance subscale total score were 0.880 and 0.855, respectively. The test- retest reliability correlation coefficients for the fear subscale, avoidance subscale and the total score were 0.890, 0.925 and 0.918, respectively (p<0.001 for all). Conclusions: The cut off score of 55.5had the optimum sensitivity and specificity for the LSAS-SR Tamil version. It had good internal consistency and test-retest reliability. Further studies will enable the assessment of the prevalence of social phobia and investigation of cultural and environmental factors associated with social phobia in Sri Lanka.

    Psychological impact of COVID-19 among a cohort of Sri Lankan medical students: Preliminary results
    (Sri Lanka College of Psychiatrists, 2022) Abayabandara-Herath, T.; Premaratne, I.; Ediriweera, D.; Chandratilake, M.; Hapangama, A.
    Previous studies report that the COVID-19 pandemic has a negative effect on the psychological wellbeing of medical students. We aimed to determine the psychological impact of COVID-19 and its associated factors among a cohort of Sri Lankan medical students, using online versions of a demographic questionnaire and the validated Sinhala and Tamil versions of the DASS-21. Of the 418 students, majority were females, aged between 20-25 years. In the study group, 40 (9.6%), 105 (25.1%) and 7 (1.6%) of participants scored above the cut-offs for the depression, anxiety and stress subscales of the DASS-21 respectively. The COVID-19 pandemic appears to be associated with a negative impact as measured by the DASS-21 scale among this group of medical students.
