We describe a combination of methods for assessing the effectiveness of complex interventions, especially where substantial heterogeneity with regard to the population, intervention, comparison, outcomes, and study design of interest is expected. We applied these methods in a recent systematic review of the effectiveness of reinforced home-based…

Given the widespread use of non-experimental (NE) methods for assessing program impacts, there is a strong need to know whether NE approaches yield causally valid results in field settings. In within-study comparison (WSC) designs, the researcher compares treatment effects from an NE with those obtained from a randomized experiment that shares the…

This paper presents a comparative case study of the alumni of two multi-term civic learning programs that combine academic service-learning with a series of other student experiences such as the creation of online portfolios and capstone experiences over at least four semesters of an undergraduate education. Findings of this study suggest that…

More aggregate data on school performance is available than ever before, opening up new possibilities for applied researchers interested in assessing the effectiveness of school-level interventions quickly and at a relatively low cost by implementing comparative interrupted times series (CITS) designs. We examine the extent to which effect…

The purpose of this study is to examine the effect of the "Violence Reduction Psychoeducation Program (VRPP) for Students Aged 11-18" on the levels of communication, conflict resolution and empathy skills of secondary school students. This research was designed as a semi-experimental design defined as "Pretest-Post-test Control…

The primary purpose of this research study was to evaluate the efficacy of BASE, a self-paced online mental health education preventive intervention with middle school students. Two hundred ninety-five adolescent students were randomly assigned to receive BASE modules (n = 156) in a regular education classroom setting over a 5-week period or to a…

Retention and student success in Science, Technology, Engineering, and Mathematics (STEM) remains a priority for institutions, and low rates of retention in STEM for underrepresented populations continues to be a concern. In this report, we compiled data from the first eight years of a STEM living-learning program focused on early engagement in…

In today's healthcare, managing chronic disease education has presented challenges for healthcare providers. Current research has indicated that the use of evidence-based practice educational tools used in conjunction with technology resources may improve patient outcomes. However the site did not have this in practice. Therefore, the purpose of…

A feature of student--teacher--scientist partnerships (STSPs) involves students working with scientists for the purpose of helping them learn more about how scientists work and think. Previous research on STSPs has generally focused on identifying the best practices of partnerships and on identifying challenges of these partnerships. The study…

The transition from childhood to adolescence often elicits psychological problems, which provides great opportunities for organizing universal, school-based prevention programs. The present study aims to evaluate the effectiveness of Boost Camp, a new prevention program targeting young adolescents' emotion regulation skills. Junior high school…

Objective: To determine the impact of a new food scholarship program on nutrient intake and dietary quality. Participants: College students (n = 49), female (78%), single (76%), average age 28 years, and white (49%). Methods: Fruits, vegetables, dairy, meat products and nonperishable foods were distributed twice a month. A one-group pretest…

This study posited that a relationship exists between information technology (IT) project managers' technical education and commercial project management certification and project management success, also known as project efficiency, for Department of Defense (DoD) IT project managers (PMs). Specifically, this research asked, "To what extent…

The increase of underprepared students entering college decreases persistence and graduation rates at postsecondary institutions, ultimately declining degree attainment and social mobility of American citizens (U.S. Department of Education, 2016; McGuire, 2018). ACT, Inc. (2017) data suggests that overwhelming percentages of high school graduates…

The efficacy and efficiency of telehealth and in-person training were compared while teaching seven undergraduate students to implement components of discrete trial training. A multiple-baseline design across skills with elements of multiple probe and delayed multiple baseline combined with an alternating-treatments design was used to evaluate the…

Background: Youth with ADHD are at risk of academic impairments, dropping out of high school, and dysfunction in young adulthood. Interventions delivered early in high school could prevent these harmful outcomes, yet few high school students with ADHD receive treatment due to limited access to intervention providers. This study will test a…
