Validation of Home Screening Questionnaire (HSQ) against Home Observation for the Measurement of Environment (HOME).

This study was done to validate the screening tool Home Screening Questionnaire (HSQ) against the gold standard Home Observation for the Measurement of Environment (HOME) inventory, using diagnostic test evaluation. Both HOME inventory and HSQ were administered by separate observers, with children less than 3 years of age, among 200 families belonging to 14 anganwadi areas. There was a high sensitivity of 83 and a high specificity of 82 observed for a cutoff point of less than or equal to 19 on HSQ against HOME Inventory as Gold Standard, as was also observed in the Receiver Operating Characteristic (ROC) curve. The likelihood ratio (LR) for positive test was 4.6 (95 % CI, 3.3 to 6.9) which implies that the families with poor home environment are 4.6 times more likely to have the HSQ score less than or equal to 19 as compared to normal families. The results of this study imply that we can confidently apply the HSQ in developmental evaluation clinics and reserve HOME inventory for research purposes.

Developmental delay and disability among under--5 children in a rural ICDS block.

We conducted this study to assess the prevalence of developmental delay, deformity and disability among 0-5 age group childrenn in Pattanakkad rural ICDS block, selected at random from among the ICDS blocks in Alappuzha District, Kerala, India. Of 12520 children upto 5 years in this block, there were a total of 311 children with developmental delay, deviation, deformity or disability giving a prevalence of 2.5 % (95 % CI, 2.22 to 2.77). The prevalence of developmental disabilities up to 2 years was 2.31 (95 % CI, 1.91 to .71) and from 2 to 5 years 2.62 % (95 % CI, 2.25 to 2.99). The prevalence obtained in the study has important policy implications for identifying childhood disabilities in the community.

CDC Kerala 8: Effectiveness of a clinic based, low intensity, early intervention for children with autism spectrum disorder in India: a naturalistic observational study.

OBJECTIVE: To document the effectiveness of low intensity, clinic based intervention models for Autism Spectrum Disorders (ASD) in countries with low disability resources. METHODS: Thirty-nine participants with a mean (SD) of 36.03(11.15) mo were assessed before and after intervention with Childhood Autism rating scale (CARS), and at baseline with the Denver Developmental Screening Test for quantifying the effectiveness of the clinic-based intervention in ameliorating autism symptoms and studying the effect of developmental disability respectively. Developmental therapists in the clinic gave low-intensity group intervention for 45-60 min to the child through mother and encouraged to continue the training, for 3-4 h, at home to address the specific goals in the three ASD symptom clusters. Most of the children were also placed in play-schools. Follow-up support was given either on a weekly, fortnightly or monthly basis. Data was analyzed using appropriate bivariate and multivariate techniques. RESULTS: There was amelioration in the severity of autism after intervention, which was statistically and clinically significant. Intervention was useful to help children with mild to severe autism. CONCLUSIONS: Low-intensity, clinic-based intervention can be effectively used in situation where there is paucity of disability resources.

CDC Kerala 10: Diagnostic accuracy of the severity scores for childhood autism rating scale in India.

OBJECTIVE: To document the diagnostic accuracy of the Childhood Autism Scale (CARS) thresholds to identify mild, moderate and severe autism in India. METHODS: The CARS scores of 623 children, with and without autism were compared against the Diagnostic and Statistical Manual for Mental Disorders 4th edition (DSM-IV-TR) for ASD diagnosis and clinical consensus between two developmental paediatricians as the reference standard for autism severity using the Receiver operating characteristics (ROC) curve analyses and contingency tables. RESULTS: The CARS total score for mild, moderate and severe autism ranged from 30.5 to 35, 35.5-40 and ≥40.5 respectively in this study. The overall diagnostic accuracy of CARS total score in the mild range was moderate [AUC = 0.68 (95%CI = 0.62-0.88), z = 1.34; P = 0.18], moderate range was high [AUC = 0.90 (95%CI = 0.77-0.97), z = 8.62; P = 0.0001] and severe range was also high [AUC = 0.85 (95%CI = 0.77-0.90), z = 7.09; P = 0.0001]. CONCLUSIONS: There are validated severity scores for Childhood Autism Rating Scale for clinical and research use in India.

CDC Kerala 11: Diagnosis of autism among children between 2 and 6 y--comparison of CARS against DSM-IV-TR.

OBJECTIVES: To compare diagnosis of childhood autism using CARS cut off scores of ≥30 and the new Indian cut off scores of ≥33 against the gold standard DSM-IV-TR criteria available during the study period 2009-10. METHODS: The study was conducted at the autism clinic of Child Development centre (CDC), Kerala. Two hundred consecutive children between 2 and 6 y with symptoms suggestive of autism were administered both CARS by a trained developmental therapist and DSM-IV-TR by a developmental pediatrician on the same day, both blind to the test results of each other. Diagnosis of autism using CARS cut off scores 30 and above, as suggested in original tool administration manual and 33 and above, as suggested for diagnostic use in Indian population was compared with DSM-IV-TR diagnosis. Data was analyzed using SPSS (version 19.0) software. RESULTS: Against DSM-IV-TR diagnosis as gold standard, the new CARS cut off scores ≥33 had a higher Specificity (74.3%), Positive predictive value (PPV) (81.9%), Positive likelihood ratio (LR) (2.66) and Negative LR (0.43), but had a lower Sensitivity (68.3%), Negative predictive value (NPV) (57.9%) and accuracy (70.5%), as compared to the cut off scores of ≥30. CONCLUSIONS: The CARS prevalence of autism for cut off points ≥30 and ≥33 was 71.5 and 52.5% respectively against 63% prevalence by DSM-IV-TR.

CDC Kerala 9: Effectiveness of low intensity home based early intervention for autism spectrum disorder in India.

OBJECTIVE: To validate effectiveness of low intensity, home based early intervention (EI) models in autism for countries with low disability resources. METHODS: Fifty-two toddlers and young children were assessed before and after intervention with Childhood Autism Rating Scale, Vineland Social Maturity Scale, and Receptive-Expressive Emergent Language Scale. Developmental and speech therapists helped mothers assemble low-cost training kits based on the developmental age of the child, gave initial training in the basic behavioral technique to address the three autism symptom clusters at home. Follow-up support was given either on a weekly, fortnightly or monthly basis. Most of the children were also placed in play-schools. Data was analyzed using appropriate bivariate and multivariate techniques. RESULTS: There was statistical and clinical amelioration in the severity of autism, with acquisition of social skills and language skills (all P = 0.001) after intervention in children with mild to severe autism. Gender showed a trend in becoming a significant predictor for intervention response. CONCLUSIONS: Low-intensity, home-based EI can be effectively used in situations where there is paucity of disability resources in countries like India, especially in primary-care and community settings.

A panchayat level primary-care approach for adolescent services.

OBJECTIVE: To develop a model for providing community adolescent care services in the primary care setting METHODS: Need assessment was done among adolescents and perceived problems of adolescents were studied using qualitative and quantitative methods. Based on the results of these studies, a Family Life Education (FLE) module was prepared. Awareness programs were organized for all stakeholders in the community on adolescent issues. All anganwadi workers in the panchayat were trained to take interactive sessions for all the adolescents in the panchayat using the FLE module. Ward based Teen Clubs were formed in all the 13 wards of the Panchayat separately for boys and girls and FLE classes were given to them through anganwadi workers. An Adolescent Clinic was set up to provide necessary medical and counseling facilities. Adolescent Health Card was distributed to all Teen Club members and those who attended the adolescent clinics. RESULTS: The present approach stresses the need and feasibility of adolescent-centered, community-based interventions. The authors' experience showed that before starting any adolescent program, community awareness generation about the need and content of the program is very important for its success. The experience of this model has made it possible to up-scale the program to seven districts of southern Kerala as a service model. CONCLUSIONS: The experiences of the program gave a realistic picture of the needs and problems of adolescents and a simple feasible model for providing services to adolescents in the primary care setting that can be easily replicated in other parts of India.
