Understanding the factors associated with variation in the implementation of educational programs has emerged as a key research focus, in an effort to identify how promising programs can be scaled up across their targeted contexts. The current study explored demographic-related variation in program dosage using a novel source of implementation…

Multi-site randomized controlled trials (RCTs) provide unbiased estimates of the average impact in the study sample. However, their ability to accurately predict the impact for individual sites outside the study sample, to inform local policy decisions, is largely unknown. To extend prior research on this question, we analyzed six multi-site RCTs…

Background: It has become increasingly important to shift education research and programming from a deficit focused perspective to a positive youth development perspective in order to identify and promote factors that support students' positive functioning and outcomes. One outgrowth of positive youth development is Positive Mental Health (PMH),…

Background: Offspring of anxious parents are at increased risk for developing anxiety disorders. There is a need to identify which youth are at greatest risk for disorder onset in this population. Objective: This study prospectively examined several theory-based family and parent characteristics (e.g., family conflict, parental over-control,…

Anxiety interventions involving social skills training and CBT for youth with ASD have shown promise, but few studies have examined the effects on social functioning or the maintenance of treatment gains. This study evaluated change in social skills during a randomized controlled trial of CBT and during the 1-year follow-up for 25 adolescents with…

Based on a one-year longitudinal experimental study with 3,782 kindergarten school children across 15 countries, this article examines the association between prayer and happiness. Results show that the post-test scores on the faces scale were higher for the participant group who had taken the prayer lessons vis-à-vis the comparison group.…

Despite schools increasingly adopting multitiered systems of support (MTSS) for prevention and intervention of mental health concerns, many are slow to adopt universal mental health screening (UMHS), a core MTSS feature, due to concerns about their limited capacity to meet the needs of all identified. In this study, we examined differences in the…

Background: Native Hawaiians and other Pacific Islanders have high rates of overweight and obesity compared with other ethnic groups in Hawai'i. Effective weight loss and weight loss-maintenance programs are needed to address obesity and obesity-related health inequities for this group. Aims: Compare the effectiveness of a 9-month, worksite-based,…

Objective: To evaluate an intervention aimed at increasing human papillomavirus (HPV) vaccine completion of the 3-dose series and knowledge. Participants: Two hundred sixty-four male and female US college students 18-26 years old who were receiving HPV vaccine dose 1. Methods: Students were randomly assigned to the intervention or control group.…

Multisite trials, in which individuals are randomly assigned to alternative treatment arms within sites, offer an excellent opportunity to estimate the cross-site average effect of treatment assignment (intent to treat or ITT) "and" the amount by which this impact varies across sites. Although both of these statistics are substantively…

Rates of participation in intervention research have not been extensively studied within autism spectrum disorder. Such research is important given the benefit of early intervention on long-term prognosis for children with autism spectrum disorder. The goals of this study were to examine how family demographic factors predicted treatment…

Using structural equation modeling, we examined the relationship of Hispanicism on recent substance use and whether Americanism moderated the effect in a sample of 1,141 Hispanic adolescents. The Bicultural Involvement Questionnaire (BIQ) was used to determine the degree of individual comfort in both Hispanic (Hispanicism) and American…

The present study examined the effectiveness of the oral history approach with respect to students' historical competence. A total of 35 ninth-grade classes (N = 900) in Germany were randomly assigned to one of four conditions--live, video, text, or a (nontreated) control group--in a pretest, posttest, and follow-up design. Comparing the three…

Background: Social relationships can serve as important risk or protective factors for child development in general, and academic adjustment in particular. Aims: This study investigated the role of teacher-child interactions in academic adjustment among preschool boys at risk of externalizing behaviour, using a randomized controlled trial study…

Recognizing that standardized instructional treatments may not be equally effective across contexts, a growing number of scholars are arguing that the strategy of adopting packaged programs and striving to implement them faithfully is neither realistic nor desirable. An alternative view is that scaling up educational treatments requires balancing…
