Adapting the colorado learning difficulties questionnaire into sinhala for the local context
(University of Kelaniya, Sri Lanka, 2022) Abeyrathne, M.K.A.U.; Danthanarayana, N.D.
Background: In Sri Lanka, there are only limited standardized tools to assess for learning difficulties. The purpose of this study was to translate, cross-culturally adapt, and validate the Colorado Learning Difficulties Questionnaire (CLDQ) into the Sinhala language. Objectives: The main objective was to translate and cross-culturally adapt the CLDQ into the Sinhala Language for children aged between 6 to 10 years. The study assessed the content validity, known group validity, and reliability and examined the association between scores of the tool and background variables. Methods: A Delphi study was conducted to cross-culturally adapt the CLDQ and a cross-sectional study was undertaken to assess the reliability and validity of the CLDQ. There were 30 parents of children with learning difficulties in a clinical setting in the Gampaha district and 30 parents of children with typical development aged between 6-10 years in a school setting in the Gampaha district using convenience sampling. Two Delphi rounds were conducted with 8 experts to adapt the questionnaire. The data was collected using an online survey. Results: The mean age of both groups was 8 years. The content validity was excellent in the translated and adapted CLDQ. It had excellent reliability in the group of children with learning difficulties. There was a significant difference in CLDQ scores between the normative and clinical groups, which emphasized known group validity. There was no significant difference in CLDQ scores and the gender of participants in the clinical group. There was a significant negative correlation between CLDQ scores and the duration of accessing therapy services by children with learning difficulties. Conclusion: This tool was effectively translated, adapted, and validated. It has excellent content validity and high reliability for children with learning difficulties. The tool was able to discriminate the children with learning difficulties via known group validity. It strongly correlated negatively with the tool's final score and access to therapy. The relevant information from the parents on their child’s earning difficulties could be gathered using this translated, adapted, and validated tool.
Translation and cross-cultural adaptation of the quantitative checklist for autism in toddlers parental questionnaire into Sri Lankan tamil language
(University of Kelaniya, Sri Lanka, 2022) Thevathasan, M.; Danthanarayana, N.D.; Yahampath., N.
Background: The Quantitative Checklist for Autism in Toddlers (Q-CHAT) is a parent-report screening tool to detect autism spectrum disorder (ASD) symptoms in toddlers aged between 18-24 months. Early detection of ASD increases the chance of receiving timely intervention. The parent report questionnaire is a good way to screen for ASD. The Q-CHAT is a novel screening tool that has demonstrated to have various benefits over conventional screening techniques, because there is a lack of screening tools for the early screening of ASD traits in the Sri Lankan Tamil clinical context. Objectives: The objectives of this study were to translate and cross-culturally adapt the Quantitative Checklist for Autism in Toddlers Parental questionnaire into the Sri Lankan Tamil language. Methods: At the initial step of this study, the Delphi study design was used to translate and cross-culturally adapt into the Sri Lankan Tamil language and a cross-sectional study conducted for psychometric evaluation. Following this, an appropriate sample was selected, which included 30 typically developing Tamil speaking toddlers aged between 18-24 months and 30 ASD Tamil speaking toddlers aged between 18-24 months. Cronbach’s alpha coefficient was used to evaluate the internal consistency of the Tamil version of the Q-CHAT questionnaire. Furthermore, the Mann-Whitney U test was used to investigate whether the Tamil version of the Q-CHAT can adequately discriminate between typically developing toddlers and toddlers with ASD. Spearman’s’ rho correlation coefficient test was used to analyse the correlation between the background variables of toddlers with ASD and the Q-CHAT scores. Results: The typically developing group consisted of 30 toddlers with the mean age of 20.17 (SD=1.44) months and the ASD group included 30 toddlers with the mean age of 20.93 (1.05) months. The mean Q-CHAT score of the typically developing toddlers was 21.23 (SD=7.59) and the mean Q-CHAT score of toddlers with ASD was 53.30 (SD=6.88). The Cronbach’s alpha coefficient for the ASD group and the normative group was 0.64 and 0.07 respectively, which indicated poor reliability. Although the translated and adapted Q-CHAT had poor reliability, it can discriminate between the typically developing toddlers and toddlers with ASD since there was a statistically significant difference in Q-CHAT scores between the two groups. Conclusion: The Tamil version of the Q-CHAT has discriminative ability, and it can be used as a screening tool for detecting children who are at risk of autism. Further validation studies with large samples are required.
