Item Randomized Controlled Trial Investigating the Effectiveness of Cognitive Behaviour Group Therapy Compared to a Waitlist Control in the Treatment of University Students with Social Phobia(Sri Lanka Medical Association, 2020) Hapangama, A.; de Silva, B.G.R.; de Zoysa, P.T.; Kuruppuarachchi, K.A.L.A.; Ravindran, A.; Wickremasinghe, A.R.; Williams, S.S.INTRODUCTION AND OBJECTIVES: Social phobia causes significant impairment in a person’s personal and professional life. However, individually delivered cognitive behavioural therapy (CBT) is costly, limited by the number of trained therapists and not scalable to meet the need for such therapy in the population. In this context, cognitive behavioral group therapy (CBGT) is the viable option. Objective was to determine the treatment effectiveness of CBGT as compared to a waitlist control of university students with social phobia. METHOD: A single-blind randomized controlled trial consisting of an 8-week treatment phase of CBGT versus a waitlist control was conducted among university students with social phobia. The Liebowitz Social Anxiety Scale –Self Rated Sinhala version (LSAS-SR) was administered at screening, baseline, four weeks and eight weeks of the trial. A culturally adapted CBGT was delivered in Sinhala to the intervention group by a trained clinical psychologist. RESULTS: Thirty university students (15 in each arm) with a mean age of 22, meeting DSM IV criteria for Social Anxiety Disorder were included. Repeated measure analysis of the total scores of the LSAS-SR in the CBGT arm showed statistically significant (p<0.001) reduction in the total scores (13.3) as compared to the waitlist arm after controlling for age and gender. CONCLUSION: CBGT is superior to waitlist control in university students with social phobia.Item Cross-cultural adaptation and validation of the Leibowitz Social Anxiety Scale (LSAS-SR) sinhala version(Sri Lanka Medical Association, 2020) Hapangama, A.; Kuruppuarachchi, L.

SETTING: Ragama Rheumatology and Rehabilitation Hospital, Ragama, Sri Lanka. METHODS: The Spinal Cord Independence Measure, Benefit Through Spirituality/Religiosity Scale, Sheehan Disability Inventory and Beck Depression Inventory-II (BDI-II) were administered to 61 consenting in-patients with traumatic SCI between June and July 2014. A linear regression model on BDI-II score was developed to examine the impact of self-perceived functional impairment and S/R activities on psychiatric outcomes in context of various sociodemographic variables.RESULTS: Psychiatric consequences of SCI were reflected in a 41% prevalence of depression. Thirty-six percent (R2=0.36) of the variance in BDI-II scores (F(5, 55)=6.07, P<0.001) was explained by the regression model. Functional impairment (β=0.54, t(55)=4.73, P<0.001) and perceived benefit through S/R activities (β=-0.31, t(55)=-2.55, P<0.05) emerged as the strongest predictors for depression severity.CONCLUSIONS: Perceived functional impairment in work, social and family domains predicted depressive symptomatology among SCI inpatients in Sri Lanka, while perceived benefit through S/R protected against depression. The findings emphasize the need for rehabilitative programming to support patients' S/R activities and mental wellbeing, promoting reintegration into their community roles.
