The daily report card (DRC) is a commonly used behavioral intervention in which teachers rate child performance on target goals and parents provide home rewards based on the child's performance. The current study investigated associations between child externalizing problems, empathy, and specific components of the DRC: (1) types of DRC goals that…

Early caregiving experiences influence the development of children's social behaviors. Caregiving hostility, characterized by anger and rejection toward the child, is associated with higher levels of aggression and lower levels of prosocial behavior. Symptoms of Attention-Deficit Hyperactivity Disorder (ADHD) may underlie the association between…

This report investigates the implementation of Positive Behavior Interventions and Supports (PBIS) during the COVID-19 pandemic and its effects on school discipline. It highlights the challenges faced by educators, including increased student problem behaviors due to disruptions in traditional schooling. The study evaluates how different tiers of…

Naturalistic developmental behavioral interventions target developmentally appropriate skills in young children with autism spectrum disorders using behavioral techniques in naturalistic interactions. Naturalistic developmental behavioral interventions demonstrate strong empirical support and frequently utilize caregiver training of intervention…

Background: We aimed to identify key factors in implementing and adhering to positive behaviour support (PBS), provided by frontline staff, targeting challenging behaviours of people with intellectual disabilities living in residential group homes. Method: Using semi-structured interviews with 12 frontline staff members, we collected perspectives…

Premack principle, often referred to as Grandma's law, describes how individuals will perform an arduous or undesirable activity if given access to a desirable activity after the completion of the original task. Premack discovered that highly preferred restricted activities in and of themselves can be reinforcing when preceded by activities that…

The effectiveness of Positive Behavioral Interventions and Supports (PBIS) in reducing major misbehavior has been demonstrated in many research studies. However, no research on the effects of PBIS on student behavior has been conducted in Quebec and other French-speaking regions. This study focuses on the results of PBIS implementation in Quebec…

Relational bullying is a prevalent issue in higher education, and students who witness bullying incidents react in prosocial or antisocial ways depending on a complex range of factors. To encourage prosocial and discourage antisocial bystander behaviours in students, it is crucial to understand which factors contribute to aggressively defending…

Recently, cases of harm have surfaced in competitive dance. The purpose of this study was to explore experiences of harm in competitive dance, specifically focusing on interactions between dancers and instructors. Semi-structured interviews were conducted with 24 competitive dancers of various gender and racial identities. Data were analyzed using…

The behavior-analytic approach to the assessment and treatment of problem behavior begins with a functional behavior assessment and concludes with function-based treatment implementation. Extinction bursts and the resurgence of problem behavior represent common barriers to successfully implementing these treatments. Recent research documents a…

Coping Power (CP) is a preventive intervention that focuses on reducing child externalizing problems. Although it is typically delivered in a group format (GCP), individually-delivered CP (ICP) has produced greater mean reductions in externalizing problems. However, standard analysis of randomized trials loses individual-level information…

Although function-based treatments have been proven to decrease challenging behavior, it is unclear whether these results translate to socially significant outcomes. In fact, researchers rarely analyze what happens outside the highly controlled setting in which behavior analytic sessions typically occur. In our first study, we used a changing…

The focus of this doctoral project was to investigate the implementation of a new behavioral management system, Positive Behaviors Intervention and Support (PBIS), by the teaching staff in grades K-6 at a specific school. The aim of PBIS is to create a consistent set of behavior expectations across the entire campus, rather than just within…

Health messaging can be a successful tool in encouraging pro-social behavior, such as bystander intervention in sexual violence situations. This dissertation explored the development of a social media message to encourage bystander intervention among college students using multiple theoretical frameworks: social norms approach and bystander…

Previous studies have suggested that bullying may be contagious in adolescents. The present study examined whether ego depletion mediated the association between peer bullying and participant bullying and whether the mediating process was moderated by participant trait self-control. A sample of 2217 Chinese high school students (16.92 ± 0.94…
