OBJECTIVE: To examine the reliability and validity of the 42-item Brief Infant-Toddler Social and Emotional Assessment (BITSEA), a screener for social-emotional/behavioral problems and delays in competence. METHOD: Parents in a representative healthy birth cohort of 1,237 infants aged 12 to 36 months completed the Infant-Toddler Social and Emotional Assessment (ITSEA)/BITSEA, the Child Behavior Checklist (CBCL)/1.5-5, the MacArthur Communication Developmental Inventory vocabulary checklist, and worry questions. In a subsample, independent evaluators rated infant-toddler behavior. RESULTS: Test-retest reliability was excellent and interrater agreement (mother/father and parent/child-care provider) was good. Supporting validity, BITSEA problems correlated with concurrent evaluator problem ratings and CBCL/1.5-5 scores and also predicted CBCL/1.5-5 and ITSEA problem scores one year later. BITSEA measures of competence correlated with concurrent observed competence and predicted later ITSEA competence measures. Supporting discriminant validity, only 23% of high BITSEA problem scorers had delayed vocabulary. Moreover, the combined BITSEA problem/competence cutpoints identified 85% of subclinical/clinical CBCL/1.5-5 scores, while maintaining acceptable specificity (75%). CONCLUSIONS: Findings support the BITSEA as a screener for social-emotional/behavioral problems and delays in social-emotional competence.
The evaluation of the withdrawal reaction in small children using a standardized instrument should take into account the child's psychopatologic context and its child's development moment. We present the BADS questionnaire validation by its application in 35 children aged 0 to 2 years-old with pediatric diseases, coming from Santa Casa de São Paulo. The results were compared with those of 90 normal children who were evaluated in a previous study of the same author. The test used was the independent t test, with mean scores of 5.90 +/- 2.57 for normal children and 6.37 +/- 4.83 for sick children, with p= 0,651 and significance level of 5%. Thus, it was observed that the withdrawal reaction in sick children is not significantly different for that for normal children. With these results, the scale shows its importance as a screening instrument.
