Item Knowledge and practices regarding COVID-19 preventive measures among the patients admitted to a general medical ward(Faculty of Medicine, University of Kelaniya, Sri Lanka, 2021) de Silva, R.; Wanigasuriya, R.; Marasinghe, C.Introduction: COVID 19 has developed into a global pandemic. Sri Lanka experiencing a major outbreak claiming many lives. Ministry of Health with other collaborators introduced precautions to be followed by the public. These included the proper wearing of masks, good hand hygiene, and social distancing. Objectives: To assess the knowledge and practices regarding COVID-19 preventive measures among patients admitted to a general medical ward. Methods: A descriptive cross-sectional study was done at the University Medical Unit of Colombo South Teaching Hospital from May - July 2021. An interviewer-administered questionnaire was used to collect data. Results: The study sample was 70 (55.7% males), with a mean age of 52.81 years (SD - 17.22). Of them, 47.1% were educated up to O/L and 44.3% up to A/L. More than half (57.1%) were employed and 78.6% had received at least one COVID 19 vaccine. Out of the seven questions on knowledge about covid-19, 77.1% scored 7/7, 20% scored 6/7, and the rest scored 5/6. Majority (98.6%) wore masks in public places and 25.7% experienced breathing difficulties. Out of the 12 steps of proper wearing masks, 4.3% followed all, 37.1% followed 9-11 and 52.9% followed 6-8 steps. For hand hygiene, 94.3% used soap and water and 40% used alcohol rub. Social distancing was maintained by 80.3%. Conclusion: Patients admitted to the general medical ward had good knowledge about COVID 19. Although most patients wear masks, proper technique is not followed by the majority. People attempt to keep good hand hygiene but social distancing is sub-optimal.Item Randomized controlled trial evaluating the effectiveness of cognitive behaviour group therapy (CBGT) compared to a waitlist control in the treatment of university students with social anxiety disorder(Postgraduate Institute of Medicine University of Colombo, 2021) Hapangama, A.; de Silva, R.; Williams, S.S.; de Zoysa, P.T.; Wickremasinghe, R.R.; Kuruppuarachchi, K.A.L.A.; Ravindran, A.BACKGROUND: Social anxiety disorder (SAD) is a common mental illness that causes significant functional impairment. Individually delivered cognitive behavioural therapy (CBT) is an effective but costly intervention with limited access, and is poorly scalable to meet the need in the population. In this context, cognitive behavioural group therapy (CBGT) is a more viable option. OBJECTIVE: To determine the effectiveness of CBGT as compared to a waitlist control for university students with SAD. METHODS: A single-blind randomized controlled trial consisting of an 8-week treatment of CBGT (N=15) versus a waitlist control (N=15) was conducted in university students meeting Diagnostic and Statistical Manual 5 criteria for SAD. The Liebowitz Social Anxiety Scale –Self Rated Sinhala version (LSAS-SR) was administered at screening, baseline, four weeks and eight weeks of the trial. Manualized and Culturally adopted CBGT was delivered in Sinhala language, to the intervention group by a licensed clinical psychologist. RESULTS: The mean age of the study population was 22 (SD=1.345) and baseline mean LSAS-SR score was 72.33 in the experimental arm and 69.03 in the wait list control. Repeated measures analysis revealed that the mean total score of the LSAS-SR in the CBGT arm was significantly lower (13.262; p<0.001) post-intervention compared to the waitlist group after controlling for age and gender. CONCLUSION: Culturally adapted CBGT in Sinhala for SAD is effective in ameliorating social anxiety symptoms among university students.
