The behavioural inhibition scale for children aged 3 to 6 (bis 3-6): Validity based on its relation with observational measures

The aim of this study is to explore the concurrent validity of the Behavioral Inhibition Scale 3-6 (BIS 3-6), a scale created for the early detection of the temperamental disposition toward social anxiety. Seventy-three participants were randomly selected from a wide sample of preschool-age children to undergo systematic observation using the Behavioral Inhibition Paradigm. Parents and teachers rated the BIS 3-6. Clinicians and researchers also measured behavioral inhibition. The BIS 3-6 scores correlate between r00.2 and r00.6 with the observational indicators, and all correlations are in the expected direction. A discriminant analysis supports a good capability of the BIS 3-6 scores to identify extreme inhibition. Consistent with previous research and given the discrepancy among parent and teacher reports and observational measures, the moderate convergence among the BIS 3-6 traitmeasurements and the observational state-measurements support the validity of the BIS 3-6 scores. This study advances the validation process for a new tool intended to early detect impairing behavioral inhibition. © Springer Science+Business Media, LLC 2012.
