Adaptive behaviour is crucial for well-being and independence. The Adaptive Behaviour Assessment System (ABAS-3) is often used to plan individualised support in specialist educational settings, drawing on both teacher and parent informants. In practice, however, little is known about the extent of variation between informants. We examined…

For students with severe or complex challenging behavior, incorporating hypothesis testing as a component of functional behavior assessment (FBA) is often warranted. Several hypothesis testing strategies (i.e., functional analysis, antecedent analysis, concurrent operant analysis) can confirm whether and how features of a student's environment…

Early childhood teachers receive some training related to overall classroom management but report receiving little training and support when working with children who engage in challenging behaviour. To alleviate the barriers to supporting students who engage in challenging behaviour, it may be helpful to implement a technology tool that provides…

Social, emotional, and behavioral (SEB) instruments are currently used in schools to screen, refer, and progress monitor students. Although many of these instruments have demonstrated strong technical adequacy, there has been far less examination of their consequential validity--that is, positive or negative intended and unintended consequences of…

Several hypothesis testing strategies (i.e., functional analysis, antecedent analysis, concurrent operant analysis) can confirm whether and how features of a student's environment…

In this replication and extension study, we examined the effects of educators' participation in practice-based professional learning (PBPL) to design, implement, and evaluate functional assessment-based interventions (FABIs). We randomly assigned school-site teams (k = 69; N = 342) to cohorts trained by either university or state technical…

Data from multiple school sources, including informant ratings, systematic direct observations (SDOs), and school wide data (e.g., office disciplinary referrals [ODRs]) are routinely used to guide decision making in the delivery of evidence based practices for students with externalizing and internalizing behavior problems. Over 50 years of…
