A variety of measures have been developed to quantify intervention effects for single-case experimental design studies. Within the family of non-overlap indices, the Tau-U measure is one of the most popular indices. There are several Tau-U variants, each one calculated differently. The appropriateness of each Tau-U variant depends upon the data…

This article is a discovery-based instructional resource for faculty to use as a capstone course or exploratory project for undergraduates who are familiar with (but not necessarily fluent in) calculus, linear algebra, complex variables, and geometry. The explorations flow from a simple change in sign: in the complex numbers a + bi, where…

Children in out-of-home care persistently show poorer educational and developmental outcomes than their peers. This study investigates the effect of the comprehensive educational intervention, "LUKoP," in a randomized controlled trial, compared to treatment-as-usual (TAU). Outcome measures included reading and math abilities, IQ and…

Feasibility, acceptability and effectiveness data of a virtual adaptation of the WHO Caregiver Skills Training (CST; n = 25) were compared with those of a pilot RCT of CST delivered in person (n = 43) against treatment as usual (TAU; n = 43). Virtual CST was delivered with high levels of integrity, but received lower ratings in some caregiver- and…

This study examined the sustained and moderating effects of a behavioural sleep intervention for autistic children in a randomised controlled trial. Autistic children (5-13 years) with sleep problems were randomised to the Sleeping Sound intervention or Treatment as Usual (TAU). At 12-month follow-up (n = 150), caregivers of children in the…

To present time-varying evidence, cumulative meta-analysis (CMA) updates results of previous meta-analyses to incorporate new study results. We investigate the properties of CMA, suggest possible improvements and provide the first in-depth simulation study of the use of CMA and CUSUM methods for detection of temporal trends in random-effects…

The Mystery Motivator intervention has been shown to increase prosocial behavior among school-age children by capitalizing on the anticipation afforded by reward concealment or randomization. Although numerous evaluations have supported the effectiveness of the Mystery Motivator, the overall status of this intervention is still unknown. The…

Versions of cognitive behavioral therapy (Coping Cat, CC; Behavioral Interventions for Anxiety in Children with Autism, BIACA) have shown efficacy in treating anxiety among youth with autism spectrum disorder. Measures of efficacy have been primarily nomothetic symptom severity assessments. The current study examined idiographic coping outcomes in…

Pivotal Response Treatment (PRT) is promising for children with Autism Spectrum Disorder (ASD), but more methodologically robust designed studies are needed. In this randomized controlled trial, forty-four children with ASD, aged 9-15 years, were randomly allocated to PRT (n = 22) or treatment-as-usual (TAU; n = 22). Measurements were obtained…

Background: Moderate-to-vigorous physical activity (MVPA) declines during adolescence, particularly among girls. In this randomized control trial, we examined MVPA in a physical activity intervention compared to physical education (PE) class as usual (TAU), stratified by sex and weight classification. Standardized BMI (zBMI) overtime was also…

The current study compared the effectiveness of a school-clinician administered cognitive behavioral treatment (CBT) to treatment as usual (TAU) at post-treatment (i.e., after 12 weeks) and at a 1 year follow-up. Sixty-two school-based clinicians (37 in CBT; 25 in TAU) and 216 students (148 students in CBT; 68 in TAU) participated. Students were…

The purpose of this study was to determine whether the augmented reality in children with autism spectrum disorder is an evidence-based practice. For this purpose, a systematic literature review was conducted for determining research that implemented the augmented reality. The review followed the Preferred Reporting Items for Systematic reviews…

In the current study, we examined the effect of cognitive apprenticeship with contextualized language instruction on students with LD (SWLDs) and English learners' (ELs) ability to compose scientific explanations using a multiple-probe, multiple-baseline single-case design. Six middle school students (three in each subgroup) participated in ten…

The present multiprobe single-case design study investigated the impact of integrating evidence-based behavioral supports into a small-group reading intervention on student engagement and disruptive behavior for six upper elementary students with co-occurring reading difficulties and inattention. Visual analysis suggested a functional relation for…

Brief experimental analyses (BEA) have been primarily used to evaluate the effects of interventional variables on reading fluency deficits. This study expanded this area of research by examining spelling interventions for students with below grade level spelling achievement. Researchers analyzed interventions addressing motivation, practice…
