This study examines the cost effectiveness of two interventions for disruptive behavior problems: First Step Next (FSN), a school-based intervention, and a multicomponent intervention that combined FSN with a home-based intervention, homeBase (hB). Analyses were based on findings from a large-scale comparative efficacy trial in the United States…

The purpose of this study was to examine semester-long referral data from a ninth-grade cohort in a public school in a southeastern state. The research question for this study was the following: What will the examination of semester-long referral data from the entire ninth-grade cohort of a public school in a southeastern state reveal? The problem…

The American School Shooting Study (TASSS) is an ongoing mixed-method project funded by the National Institute of Justice to catalog US school shootings. It has amassed data based on open sources and other public materials dating back to 1990. This brief presents new insights from TASSS, diving deeper into the database's potential to examine the…

Background: There is a growing body of research focused on autistic individuals who present with aggressive behaviour. Aggressive behaviour has been found to occur more frequently in autism compared with other developmental disabilities or the general population. The most common types of aggressive behaviours are self-injurious behaviours,…

Social, emotional, and behavioral interventions are often complicated to implement in school settings. Empirical and practical evidence suggests that educators need support to implement interventions with treatment integrity or as intended. Treatment integrity is comprised of multiple dimensions that capture quantity of the intervention delivered,…

The Premack principle states that any Response A can reinforce any other Response B if the independent rate of A is greater than the independent rate of B (Premack, 1959). Applying the Premack principle involves arranging the environment to restrict access to certain responses based on relative probabilities of a set of given responses (Timberlake…

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…

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…

The interactions between sleep problems, autism symptoms and emotional and behavioural difficulties were explored using network analysis in 240 autistic children (mean age: 8.8 years, range 5-13 years) with moderate to severe sleep problems. Findings revealed a highly connected and interpretable network, with three separate clusters identified of…

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…

Classroom behaviour management is a persistent and often overwhelming challenge for novice teachers; they face frequent disruptive behaviours that they struggle to resolve effectively, which harms both the teaching process and classroom climate. This study investigates the specific strategies novice teachers use to manage behaviour, detailing what…

Background: Impacts of dementia syndromes on caregivers are well established, but research specific to Primary Progressive Aphasia (PPA) populations is scant. In particular, little is known about the impacts of non-language symptoms (e.g., emotion recognition and behavioural disturbance) on caregiver outcomes in PPA. Aims: The present study sought…

Objective: This article examines impacts of student resilience, school climate, and barriers to mental health care on problematic drinking behavior and cannabis use among rural university students. Participants: A total of 948 students from a public university in a southeastern state that completed the 2019-2020 Healthy Minds Study. Methods:…

Sexually aggressive behavior, risky-sexual behavior, and heavy episodic drinking are interrelated behavioral-health problems among college men. College men reporting these problems, relative to peers, report lower use of protective behavioral strategies (PBS), which are cognitive-behavioral, harm-reduction strategies. College men exhibiting heavy…

Phelan-McDermid syndrome (PMS), caused by "SHANK3" haploinsufficiency, lacks natural history data. We report the trajectory of adaptive behavior from a prospective, longitudinal, natural history study. English-speaking people aged 3-21 years with a PMS molecular diagnosis were followed over 2 years. We analyzed longitudinal Vineland…
