Anti-bullying programs can create more positive classroom environments by fostering the development of positive leaders who establish constructive norms. The social identity theory of leadership addresses stability and change within different leader profiles and identifies leader group prototypicality: the extent to which leaders are perceived to…

Evidence-based robotic intervention programmes for children with autism spectrum disorder (ASD) have been limited. As yet, there is insufficient evidence to inform therapists, teachers, and service providers on effectiveness of robotic intervention to enhance social development and participation of children with ASD in a real context. This study…

Background: Despite the growing interest in school-based mindfulness training (SBMT) and its evaluation, evidence on the effectiveness of SBMT is still limited and somewhat inconsistent. Further, knowledge on the role of implementation quality, which is essential for a more widespread use of SBMT, is scarce. Objective: This study examined effects…

Objective: We investigated the preliminary efficacy of a tailored human papillomavirus (HPV) vaccination on-line intervention designed to increase HPV vaccination intention. Participants: Female college students (N = 101; 18-26 years), who have not received the HPV vaccine. Methods: Participants were randomized to either a control group to read…

The purpose of this study was to evaluate the effectiveness of Social Thinking® Social Behavior Mapping (SBM) on adolescents with autism spectrum disorder. A pretest-posttest control group design with matched sampling was used. There were 22 participants between the ages of 13 and 17 who were matched by age and IQ and then were randomly assigned…

Behavioral activation (BA) has significant and long-lasting effects on depression in adults, and a growing body of evidence supports its efficacy with adolescents. It remains unclear, however, whether BA reduces systematically-observed depressive behavior in addition to subjective report of depressive symptoms. In this single-case study, three…

College students are at a heightened risk of experiencing depression and anxiety symptomatology and engaging in maladaptive alcohol use. Understanding how alcohol interventions impact emotional functioning is essential. One such intervention uses Deviance Regulation Theory (DRT), which posits that behavior can be modified using targeted messaging…

The purposes of the current study were to 1) develop a learning burnout assessment for Thai undergraduate students and 2) examine the effects of a positive thinking training program on Thai undergraduate students' learning burnout. The study was divided into two parts: the instrumental development of the assessment tool and the implementation of…

This study examined the relation between both implementation fidelity and quality and the outcomes of two different anti-bullying interventions targeting distinct processes involved in bullying: moral disengagement and social norms. In total, 34 French-speaking Belgian teachers from six elementary schools were trained to deliver either the moral…

Joint action routine (JAR) was implemented to help a 10-year-old student with autism spectrum disorder (ASD) improve his social skills. The implementation of JAR involved incorporating several elements into group activities. These elements included establishing a meaningful theme for the activities, assigning simple and reciprocal roles to the…

Objective: The current study evaluated the long-term effectiveness of a peer delivered suicide prevention gatekeeper training program for college students. Participants: 1,345 undergraduate students (M[subscript age] = 20.24, SD = 3.27; 89.6% White) received the peer led training during a single class-period. Method: Participants completed pre-…

Objective: To assess the effectiveness of a peer-led single-session intervention targeting the sociocultural pressures of body image. Participants: New members of 13 sororities at one university. Methods: Participants were randomized by sorority into the intervention (n = 207) or wait list control (n = 264). Online surveys were administered at…

This is the protocol for a Campbell review. The primary objective for this review is summarising the effectiveness of video-based interventions (VBI) in promoting prosocial behaviours in a population of young people with autism spectrum disorders (ASD). The research questions employed to fulfil this objective include: (1) Do VBI improve prosocial…

Dysregulation of glutamate neurotransmission plays a critical role in autism spectrum disorder (ASD) pathophysiology and is a primary target for core deficit research treatment trials. The mechanism of action of ketamine has striking overlap with the theory of ASD as a disorder of synaptic communication and neuronal networks. This two-dose,…

Bullying and sexual harassment are commonly experienced by secondary students, yet these behaviors are seldom targeted for intervention in high schools. Norms and Bystander Intervention Training (NAB IT!) is a program designed to address bullying and sexual harassment through promoting prosocial norms and helping behaviors among high school…
