Psychometric properties of the Brief Infant-Toddler Social and Emotional Assessment (BITSEA) in a sample of Chilean children

Introduction: Early childhood is a critical stage for mental health, and it is necessary to have effective tools for early detection of child behaviours related to psychopathology. Objective: to assess the psychometric properties of the Brief Infant and Toddler Social-Emotional Evaluation Scale (BITSEA) in a sample of Chilean children. Methods: 289 parents of infants and toddlers aged 12-36 months completed the BITSEA and the CBCL 11/2-5. Results: Acceptable reliability was found for the "socioemotional problems" dimension (& omega;=0.84), and low reliability for the "socioemotional competence" subscale scores (& omega;=0.59). The factor structure was adequate and high concurrent validity with other scales was observed. The confirmatory model showed acceptable fit indices (CFI= 0.94; TLI= 0.94; SRMR= 0.07; RMSEA= 0.027). Conclusion: The BITSEA in this sample showed similar results to other studies, its applicability is promising for the early detection of socioemotional problems in early childhood. It is suggested to continue its study in a nationally representative sample.
