In tackling the widespread problem of bullying victimisation, researchers have acknowledged the value of focusing on changing bullying-related beliefs and using peer-based interventions. In three studies (N = 419, 237 intervention and 182 controls), we tested the effectiveness of the CATZ cross-age teaching programme by inviting small groups of…

This three-manuscript dissertation in practice used improvement science as the methodological approach of disciplined inquiry into a problem of practice--the discrepancy of male and female participation in engineering design-based (EDB) courses and clubs in Starr School District. Manuscript 1 centered around diagnosing the problem and delved into…

Objective: Performance of Cognitive Refocusing Treatment for Insomnia (CRT-I) relative to stimulus control treatment (SCT) remains unknown among college students. This pilot trial compared single-session, electronic-based, peer-led CRT-I to SCT, and as well as awareness-based (AC) and no-treatment (NTC) controls. Participants: College students (N…

Science identity can be described as the part of oneself that relates to science, and is made up of four components: competence, performance, recognition, and interest. Science identity is important because students who have a strong science identity tend to persist longer in STEM majors and are more likely to attain a scientific career…

This study explores how peer learning and teaching interactions in undergraduate STEM courses occurred through the "Peer-Learning Assistant" (PLA) model. This is one of the active learning strategies applied in a curricular setting, and also to find out the learning experiences for STEM students and PLAs from the PLA model. For this…

Medical students report high levels of psychological distress compared to the general population, yet they also underutilize mental health services.

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…

Introduction: College students face increased risk for a variety of mental health problems but experience barriers to treatment access. Prevention programs, including those implemented by peer educators, may decrease treatment needs and increase service access. We examined the implementation of an evidence-based eating disorder prevention program,…

Purpose: Elementary-aged peers often need support for them to have positive interactions with classmates with autism who are minimally speaking (i.e., fewer than 30 functional spoken words). This study examined whether peers could learn to use responsive interaction strategies to support inclusive play and communication within a peer network…

Reading and writing are enormously valuable, influencing every area of life beyond school. However, reading and writing difficulties are on the rise, especially among second-language students.
