Brief Observation of Social Communication Change (BOSCC) Shows Promise in Tracking Social Communication Improvements in Autism
New Review Highlights BOSCC’s Ability to Detect Social Communication Changes in Autism
Measuring subtle changes in social communication among autistic children has long posed challenges for researchers and clinicians. A recent rapid review examined the Brief Observation of Social Communication Change (BOSCC), a tool designed to capture nuanced shifts in social communication and related behaviors during everyday interactions. The review synthesized findings from 19 studies involving 789 participants to assess the BOSCC’s responsiveness and validity as an outcome measure in autism research.
Key Findings from the Review
The meta-analysis revealed that the BOSCC total score showed a moderate and statistically significant improvement in intervention groups (Hedges’ g = -0.32), indicating the tool’s sensitivity to behavioral changes following various supports or programs. In contrast, control groups exhibited a smaller, non-significant change (g = -0.15).
The Social Communication subscale of the BOSCC was particularly effective, demonstrating consistent improvements in reciprocal social interactions (g = -0.34). Meanwhile, the Restricted and Repetitive Behavior (RRB) subscale showed moderate effects (g = -0.40) but with considerable variability across studies, reflecting heterogeneity in outcomes.
Comparisons with the Autism Diagnostic Observation Schedule (ADOS), a widely used diagnostic tool, suggested that the BOSCC may be more sensitive in detecting changes in social communication over time, based on a subset of four studies that reported both BOSCC and ADOS results.
Context and Interpretation
Restricted and repetitive behaviors often serve important self-regulatory and emotional functions for autistic individuals. The variability in RRB outcomes may be due to many interventions not specifically targeting these behaviors, aligning with neurodiversity-affirming approaches that respect their role in sensory processing and emotional expression.
The BOSCC’s focus on naturalistic, everyday social interactions allows it to capture subtle behavioral shifts that may be missed by traditional diagnostic assessments, making it a valuable tool for clinical trials and intervention studies.
Implications for Families and Researchers
For families and practitioners, the BOSCC offers a promising method to monitor meaningful changes in social communication skills over time, potentially informing personalized support strategies. Its sensitivity to improvements in reciprocal interaction highlights its utility in evaluating the effectiveness of social communication interventions.
Researchers are encouraged to consider the nuanced roles of repetitive behaviors when interpreting BOSCC results and to design studies that align with neurodiversity principles, ensuring that assessments respect the diverse experiences of autistic individuals.
Limitations and Considerations
While the BOSCC shows promise, the heterogeneity in RRB findings suggests caution in interpreting changes in repetitive behaviors. Additionally, the tool’s responsiveness may vary depending on the intervention focus and duration. Further research is needed to refine its use and to explore its applicability across diverse populations and settings.
Overall, the evidence supports the BOSCC, especially its Social Communication subscale, as a useful instrument to detect behavioral changes in autism research and clinical practice.
