Diffusion of innovations theory can be used to understand how to prevent or slow the spread of harmful behaviors, such as e-cigarette use in adolescent social networks. This study explores how different network intervention strategies could impact diffusion dynamics through network simulations based on observed social norms and e-cigarette use…

While there have been significant advances in the treatment of conduct disorder (CD), there is still a need to seek and develop therapeutic solutions that can overcome the poor long-term prognosis. In this evidence-based research, we evaluated the effect of immediate REACH Forgiveness training on the severity of aggressiveness among adolescents…

Suicidal thoughts and behaviors (STBs) in youth are prevalent and impairing, but available psychosocial treatments are difficult to access and show limited efficacy. "Prevention strategies" are interventions intended to be implemented during relative well-periods before impairment or other adverse outcomes set in and therefore help avoid…

Differential reinforcement of other behavior (DRO) is a commonly used reinforcement-based system for reducing problem behavior. DRO systems are particularly useful in that they are effective for the treatment of maladaptive behavior and can be individualized based on the needs of the learner.

Parents of adolescents are faced with a variety of challenges related to their children's behavior and development. Behavioral parent training (BPT) programs may be effective strategies to mitigate adverse childhood experiences (ACEs) and other common behavioral problems in the adolescent period. Adolescence is the period following the onset of…

Suicidal behaviour is a major socio-health problem worldwide. However, there are few empirically validated programs for universal prevention of suicidal behaviour in school settings.

The participants in this study were minority, high school students who displayed frequent…

To investigate the effect of psychosocial interventions on emotion regulation outcomes in children and youth (0-23 years). We conducted a meta-analysis using a three-level modeling approach extracting multiple effect-sizes from experimental and quasi-experimental studies. We included 40 interventions from 35 publications involving 3,891…

The success of Positive Behavioral Interventions and Supports (PBIS) in typical schools has led to interest in PBIS for alternative programs, including residential programs. In this brief, we describe PBIS as implemented in a therapeutic treatment home for adolescents with mental health needs. The PBIS framework enabled the program to add Tier 1…

Challenging behavior tends to increase in levels during adolescence for individuals with developmental disabilities (DD). If not addressed, this can lead to negative post-school outcomes for adolescents with DD. The purposes of this meta-analysis were to examine the effects of behavioral intervention in reducing challenging behaviors of…
