RESUMO
Measuring classroom behavior among young children is important to guide assessment and intervention decisions, yet there is limited literature on appropriate direct observation tools for this purpose. This article describes the psychometric properties of the Behavior Assessment System for Children, Student Observation System (BASC-3 SOS) with 135 children ages 20 to 67 months (M = 35 months, 64% Latinx, 78% with an established developmental disability) and their teachers (N = 36) as part of a larger randomized control trial of a teacher training intervention. Inter-rater reliability on individual BASC-3 SOS behaviors ranged from poor to good. Correlations between BASC-3 SOS scores across time indicated low to moderate developmental test-retest reliability. Significant correlations between BASC-3 SOS scores and teacher ratings provided evidence for convergent, divergent, and predictive validity. Differences between BASC-3 SOS scores for children with versus without disabilities supported the tool's discriminant validity. There were no significant pre- to post-treatment changes in BASC-3 SOS scores. Overall, results provide mixed evidence for the psychometric properties of the BASC-3 SOS when used with young, diverse children with and without disabilities. Implications for clinical and research purposes are discussed. SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1007/s10864-021-09458-x.
RESUMO
Using a pilot matched-pairs cluster-randomized control trial, we evaluated the acceptability and preliminary outcomes of universal Teacher-Child Interaction Training (TCIT-U) with students with disabilities in early special education programs. Twelve classrooms (clusters) were paired by age and type and then randomly assigned within pairs to either TCIT-U (81 students, 20 teachers) or wait-list control (63 students, 16 teachers) with services as usual. We analyzed the effects of TCIT-U on (a) teachers' skills acquisition via masked observational coding and (b) students' behavior and developmental functioning via teacher questionnaires. For child-directed interaction skills, teachers receiving TCIT-U exhibited significantly greater increases in behavior descriptions and labeled praise than teachers who did not receive TCIT-U at posttreatment and follow-up. No significant group differences were observed in use of teacher-directed interaction skills. Qualitative data from teachers expanded on these findings, suggesting that teachers found child-directed interaction skills more acceptable than teacher-directed interaction skills. Teachers receiving TCIT-U reported small but significant improvements in student behavior problems and socioemotional functioning at posttreatment and follow-up, as compared to wait-list students. We discuss considerations for future implementation and tailoring of TCIT for young students with disabilities, which may have positive impacts on future cohorts of students beyond teachers' initial training.
