    The association between negative experiences during childhood and social anxiety disorder: A cross-sectional study among Sri Lankan university students
    (Sri Lanka Medical Association, 2023) de Silva, B.G.R.; De Zoysa, P.T.; Pathmeswaran, A.; Williams, S.S.
    INTRODUCTION: Social Anxiety Disorder (SAD) demonstrates early-onset, chronic course, and impairment in all social spheres. OBJECTIVES: The study objective was to explore the association between negative childhood experiences among a university student sample that indicated a high prevalence of SAD. METHODS: A cross-sectional study was conducted among 1137 students from five state universities. The Liebowitz Social Anxiety Scale – Sinhala version, and a correlates questionnaire including a culturally adapted Adverse Childhood Events Questionnaire and contextually appropriate parenting-related questions, were used as instruments. The analysis included chi-square tests for independence, spearman’s r correlations, and binary logistic regressions. RESULTS: Within the sample, 52.2% were female, and 66% were between 21-23 years. All faculties were represented with 27.5% from engineering. 32.2% of participants were first years. Bivariate analyses identified that being an eyewitness towards violence towards mother, feeling unsafe, feeling mistreated by family, experiencing physical abuse, experiencing sexual abuse, experiencing emotional abuse, experiencing parental dissatisfaction, and parental overcontrol to be significantly (p<0.05) associated with SAD. Continuous variables of Parent dissatisfaction (AOR=1.07, 95% CI 1.01-1.13, p<0.05), parent overcontrol (AOR=1.08, 95% CI 1.02-1.15, p<0.01) and experiences of emotional abuse (AOR=1.31, 95%CI 1.11-1.54, p=0.001) remained independently associated with SAD on regression analysis. CONCLUSIONS: Findings from this study corroborate the literature on the association between childhood experiences and parenting-related factors and SAD. The findings also highlight for the first time that Sri Lankan university students are no exception. An urgent need for awareness and prevention of adverse experiences within the family context, and early intervention to prevent the development of SAD are crucial.

    The validation of the Sinhala version of the Kessler psychological distress scale (K10) to screen for psychiatric morbidity
    (Sri Lanka Medical Association, 2008) Wijeratne, L.T.; Williams, S.S.; Peris, M.U.P.K.; de Silva, N.R.; Hapuarachchi, H.A.C.; Perera, K.P.J.; Kawamura, N.; Wickremasinghe, A.R.
    BACKGROUND: The Kessler psychological distress scale (K10), used in epidemiological surveys, measures psychological distress. High scores in community surveys are associated with anxiety and affective disorders, and to a lesser extent, with other psychiatric disorders. OBJECTIVE: To validate the Sinhala translations of the long (K10) and short (K.6) versions of the Kessler psychological distress scale. DESIGN, SETTING AND METHODS: The English version of K10 was translated into Sinhala. Content and face validity was assessed by experts. The scales were pre-tested and modified accordingly. The Sinhala versions of K6 and K10, and the Structured Clinical Interview Schedule were administered to 20 adults with major psychiatric illnesses diagnosed by two clinicians independently, and to a random sample of 25 apparently normal people from the community. SPSS (Version 11) was used for the analysis. RESULTS: The ROC curve for the K10 contained 96.1% of the area under the curve of 0.961 (95% CI 90.4%-100%). A cut off score of 22 for the K10 yielded a sensitivity of 93.8% and a specificity of 82.6%. The ROC curve for the K6 contained 90.1% (95% CI 80.5% - 99.7%) of the area under the curve. For the K6, a cut off score of 13 gave a sensitivity of 88.2% and a specificity of 72%, The total number of days that the patient could not attend to regular work and responsibilities was significantly correlated with both the K10 (p=0.041) andK6 (p=0.023). CONCLUSION: The Sinhala version of the K10 and K6 questionnaires can be used to screen for psychological distress.
