Nudges are a way to steer people's behavior through changes in how choices are presented. Nudge research has been incorporated into public policy in many countries, and nudge research, thus, has the potential to directly influence societies and individuals. As a result, research ethics for nudge research is needed to ensure that nudges developed…

Applied behavioral pharmacology explores how drugs may influence problem behavior in persons with intellectual and developmental disability (IDD). A comprehensive review was conducted featuring single-case experimental designs in the domain of applied behavioral pharmacology to evaluate and report on study quality. Studies included in the review…

The current study adds to a growing body of behavioral research aimed at learning about changes in behavior over time. In this proof-of-concept study, functional analyses were conducted every 6-8 weeks with eight children diagnosed with ASD receiving early intervention services at a community-based clinic. The goal of this study was to develop a…

Bayesian approach is becoming increasingly important as it provides many advantages in dealing with complex data. However, there is no well-defined model selection criterion or index in a Bayesian context. To address the challenges, new indices are needed. The goal of this study is to propose new model selection indices and to investigate their…

Composite scores are an exceptionally important psychometric tool for behavioral science research applications. A prototypical example occurs with self-report data, where researchers routinely use questionnaires with multiple items that tap into different features of a target construct. Item-level missing data are endemic to composite score…

Background: There is a high prevalence of challenging behaviors (CB) in adults with intellectual disability (ID), which lead to negative personal outcomes and diminished quality of life. Emerging evidence suggest attachment theory could be useful to address CB in adults with ID and lower the negative impact on their social environment. Methods: A…

Behavior analysts collaborating within interdisciplinary teams are likely to find themselves at difficult crossroads. Some of these crossroads include implementing alternative treatments, defining and determining risk and harm, and evaluating research and interventions. The purpose of this paper is to highlight some of these crossroads and provide…

Mediation analysis plays an important role in understanding causal processes in social and behavioral sciences. While path analysis with composite scores was criticized to yield biased parameter estimates when variables contain measurement errors, recent literature has pointed out that the population values of parameters of latent-variable models…
