Individual participant data (IPD) meta-analysis projects obtain, harmonise, and synthesise original data from multiple studies. Many IPD meta-analyses of randomised trials are initiated to identify treatment effect modifiers at the individual level, thus requiring statistical modelling of interactions between treatment effect and participant-level…

Purpose: This systematic review evaluates the latest available evidence regarding augmentative and alternative communication (AAC) interventions in children from 0 to 6 years old diagnosed with various disabilities. Method: A systematic search was conducted in MEDLINE (OVID), PsycINFO (EBSCO), ERIC (ProQuest), SCIELO (WOS), Teacher Reference…

Community health advisors (CHAs) play a key role in promoting health in medically underserved communities, including in addressing cancer disparities. There is a need to expand the research on what characteristics make for an effective CHA. We examined the relationship between CHA personal and family history of cancer, and implementation and…

Optimism bias is common across health risk assessments, including firearm injury risk, and can have behavioral consequences. Using data from the 2018 California Safety and Wellbeing Survey, we examine whether optimism bias influences firearm injury prevention practices and policy support by comparing the characteristics, behaviors, and opinions of…

This study investigated the power of two-level hierarchical linear modeling (HLM) to explain variability in intervention effectiveness between participants in context of single-case experimental design (SCED) research. HLM is a flexible technique that allows the inclusion of participant characteristics (e.g., age, gender, and disability types) as…

Background: Exposure to conflicting health information can produce negative affective and cognitive responses, including confusion and backlash, and the effects of this exposure can even "carry over" and reduce people's receptivity to subsequent messages about health behaviors for which there is scientific consensus. What is not known is…

Schools rely heavily on paraeducators to support the delivery of special education services for students with disabilities (SWDs). However, paraeducators often lack formal training in implementing evidence-based practices. Traditional methods of professional development are not effective at producing long-term changes in classroom staff. Prior…

Background: Equitable access to health care services for Hispanic and Latine populations requires that systems go beyond working to increase enrollment in health insurance but also addressing health insurance literacy--the knowledge, ability, and confidence to find and use health insurance. Methods: In collaboration with a local health policy…

Research on mathematical cognition, learning, and instruction (MCLI) often takes cognition as its point of departure and considers instruction at a later point in the research cycle. In this paper, we call for psychologists who study MCLI to reflect on the "status quo" of their research practices and to consider making instruction an…

The purpose of this study was to explore administrators' and teachers' experiences and perceptions of how restorative practice strategies impact the execution of school discipline in an urban middle school. This study included a review of data collected from interviews with middle school administrators and teachers in a large school district. A…

It is well known that perceptions of intervention characteristics (e.g., cost, source, evidence strength and quality) are a critical link from dissemination to implementation. What is less known is the process by which researchers understand the characteristics most valued by key intermediaries (i.e., real-world decision-makers), particularly in…

Background: There is little understanding of men's weight loss outcomes and behaviors in self-directed contexts, such as digital commercial mobile weight management programs. This is an especially pressing question given that men often express disinterest in weight management programs and it is unknown how that manifests in self-directed…

Competition among parties is a central feature of democratic politics, but extreme partisanship can undermine democratic practices and institutions. We report the results of a formative curricular intervention involving reflective discussions designed to avoid hyper-partisanship in a training program for anyone--including university students--with…

Background: Affective associations have been shown to predict physical activity, but interventions designed to manipulate affective associations are limited. Purpose: To increase physical activity through manipulation of affective associations toward physical activity using the values component from Acceptance and Commitment Therapy (ACT) in…

Despite the increase in federal tiered evidence initiatives that require the use of rigorous evaluation designs, such as randomized experiments, there has been limited guidance in the evaluation literature on practical strategies to implement such studies successfully. This paper provides lessons learned in executing experiments in applied…
