Most social communication tests used to measure change in young children with autism spectrum disorder have not undergone rigorous psychometric evaluation. Notably, and most relevant to the early intervention literature, there is little information on the sensitivity of these measures to change over time, despite their frequent use. Further, most…

Behaviorally anchored rating scales (BARS) are an essential component of structured interviews. Use of BARS to evaluate interviewees' performance is associated with greater predictive validity and reliability and less bias. BARS are time-consuming and expensive to construct, however. This report explores the feasibility of gathering participants'…

The criterion-related validity of divergent thinking (DT) tests has been questioned because of relatively low correlations between DT test scores and creative performance. A possible inhibiting factor in previous correlations--heterogeneity of the sample--has been ignored. If groups with different DT profiles are involved in this line of research,…

A growing number of research groups are now including older minimally verbal individuals with autism spectrum disorder in their studies to encompass the full range of heterogeneity in the population. There are numerous barriers that prevent researchers from collecting high-quality data from these individuals, in part because of the challenging…

The Daily Behavior Report Card is an intervention showing promise in various formats and in multiple settings. A meta-analysis evaluated the size of effects obtained from Daily Behavior Report Card interventions within single case research designs, investigating six potential moderators of treatment effects: student age, target behavior,…

Describing the state of the science of ABA, this comprehensive handbook provides detailed information about theory, research, and intervention. The contributors are leading ABA authorities who present current best practices in behavioral assessment and demonstrate evidence-based strategies for supporting positive behaviors and reducing problem…

Direct observation in natural settings has been recognized for nearly a century as an important methodology to capture the nuances of children's behavior for research, clinical assessment, and program evaluation. These ecologically valid descriptive data complement more widely used behavior rating scales to evaluate the impact of intervention…
