Item Translation and Validation of Abnormal Involuntary Movement Scale (AIMS) into Sinhala(Sri Lanka Medical Association, 2020) Baminiwatta, A.K.A.B.; Bandara, T.R.; Liyanage, H.; Perera, K.M.N.; Kuruppuarachchi, K.A.L.A.; Hapangama, A.INTRODUCTION AND OBJECTIVES: Tardive dyskinesia (TD) is a pattern of abnormal involuntary movements among patients on long-term antipsychotics. As there is no medication universally effective, prevention of TD is important. Non-medical clinicians are now involved in the follow-up of patients on antipsychotics in Sri Lanka; therefore, translation and validation of a screening tool in Sinhala, that can be administered by different mental health professionals, was deemed pertinent. Aim of the study was to translate and validate the Abnormal Involuntary Movement Scale (AIMS) into Sinhala. METHODS: Translation followed standard guidelines. The finalized Sinhala version was administered independently by five raters (two registrars in psychiatry, a medical officer, a community psychiatry nurse (CPN) and a psychiatry social worker) on patients on antipsychotics for a minimum of one year. The gold standard diagnosis of TD was the Diagnostic and Statistical Manual (DSM)-5 criteria conducted by a consultant psychiatrist. Sensitivity, specificity, and Cohen’s kappa values were calculated. RESULTS: Out of 137 patients, 53.3% were male. Mean age was 49 and average duration of antipsychotic treatment was 14 years. The percentage of patients diagnosed with TD using AIMS and DSM-5 were 33% and 34% respectively. Sensitivity and specificity of AIMS to detect TD were 67% and 83.4% respectively. The degree of agreement between AIMS and DSM-5 indicated moderate criterion validity (kappa= 0.5). For different raters, the kappa statistic ranged from 0.41 (CPN) to 0.63 (registrar), signifying modest reliability between raters. CONCLUSION: This provides preliminary evidence for validity and reliability of AIMS in detecting TD, when administered by a range of mental health professionals. Given the clinical experience required and the subjectivity involved in diagnosing TD, the foregoing modest statistical indicators seem reasonable.Item A nationwide survey of attitudes towards psychiatry among final-year medical students in Sri Lanka(Elsevier., 2020) Baminiwatta, A.K.A.B.; Bandara, W.A.V.S.; Athurugiriya, A.A.I.D.; Yangdon, T.; Cader, G.R.; Bokalamulla, L. A. B.; Bandara, W.R.R.D.; Bandara, W.M.K.M.; Chandradasa, K.A.S.I.P.; Athukorala, H.P.; Dias, G.S.S.R.ABSTRACT: Stigma towards psychiatry, a debilitating phenomenon worldwide, is likely to have engendered the longstanding lack of recruitment into psychiatry in Sri Lanka (SL). However, as recent expansion of the undergraduate training in psychiatry in SL may have instigated favorable changes in students' attitudes, we assessed the attitudes of students regarding psychiatry by administering Attitude towards psychiatry-30 (ATP-30) scale to final-year medical students in nine medical schools in SL. This 30-item questionnaire covers eight domains of psychiatry and is rated on a Likert scale, producing a total score out of 150. A multiple linear regression was performed to investigate associated factors. A total of 743 fin. l-year students participated. Of them, 54 % were male. The mean attitude score was 107.7 (SD = 12.3) and 92.2 % showed an overall "positive" attitude. 22.2 % of students considered psychiatry as a potential future career. Students with more than one month of clinical exposure to psychiatry showed a better attitude compared to those with shorter exposure. Female gender and the presence of a close person with mental illness were also associated with better attitudes and career interest. The generally positive attitude towards psychiatry among medical students may be explained, at least partly, by recent advances in undergraduate psychiatry education in SL. Longer clinical exposure to psychiatry being associated with better attitudes indicates the need to ensure adequate duration of clinical training in psychiatry in the undergraduate curriculum.
