The Impact of Household Dysfunction on Dating Violence Perpetration Among Adolescents in the United States
Adverse childhood experiences, such as household dysfunction (HD), play a central role in how adolescents establish, experience, and navigate the challenges of relationship formation, maintenance, and dissolution. HD exposures have been independently associated with dating violence (DV) perpetration in both adolescents and adults. However, research examining the association between the concurrent effect of HD on DV perpetration, especially among …
Household dysfunction and dating violence perpetration
Adolescent dating violence (DV) perpetration is a significant public health issue affecting millions of adolescents in the United States. Adverse childhood experiences such as household dysfunction (HD) have been exhibited to be risk factors for DV perpetration during adolescence and adulthood. Furthermore, the literature is scant regarding how positive parent-child relationships can mitigate these risk factors and decrease HD-related consequence…
Feasibility and acceptability of an implementation strategy to enhance use of classroom-based physical activity approaches in elementary schools

Elementary school staff perspectives on the implementation of physical activity approaches in practice
Introduction A whole-of-school approach is best to promote physical activity before, during, and after school. However, multicomponent programming is often complex and difficult to deliver in school settings. There is a need to better understand how components of a whole-of-school approach are implemented in practice. The objectives of this mixed methods study were to: (1) qualitatively explore physical activity approaches and their implementatio…
Observed and perceived benefits of providing physical activity opportunities in elementary schools
Introduction Schools play an important role in promoting physical activity for youth. However, school-based physical activity opportunities often compete with other academic priorities, limiting their implementation. The purpose of this study was to qualitatively explore elementary school teacher and staff perspectives on providing physical activity opportunities and how they impact students and learning. Methods We partnered with a school distri…
Examining readiness for implementing practice changes in federally qualified health centers
Implementing evidence‐based interventions remains slow in federally qualified health centers (FQHCs). The purpose of this study is to qualitatively examine the R = MC 2 ( R eadiness = m otivation × innovation specific c apacity × general c apacity) heuristic subcomponents in the context of implementing general and colorectal cancer screening (CRCS)‐related practice changes in FQHCs. We conducted 17 interviews with FQHC employees to examine (1) ex…
Using Implementation Mapping to Build Organizational Readiness
Organizational readiness is essential for high-quality implementation of innovations (programs, policies, practices, or processes). The R = MC 2 heuristic describes three readiness components necessary for implementation—the general functioning of the organization (general capacities), the ability to deliver a particular innovation (innovation-specific capacities), and the motivation to implement the innovation. In this article, we describe how w…

Evidence-Based Intervention (EBI) Mapping
EBI Mapping helps program planners understand the components and logic of an EBI. This information is important for selecting, adapting, and scaling-up EBIs. Accelerating and improving the use of existing EBIs can reduce the research-to-practice gap and improve population health
Use of School Wellness Policy Templates in One Texas Public Health Region
BACKGROUND: Federal law requires most school districts to develop school wellness policies (SWPs), which state agencies assist in by providing templates. Templates provide standard language, which districts may edit for numerous reasons. We aimed to identify the frequency/consistency of template usage and identify the types of edits districts make when using SWP templates. METHODS: We identified SWPs (N = 117) and templates (N = 2) from districts…
Physical Activity and Healthy Eating Programming in Schools to Support Student’s Health-Related Fitness
Centers for Disease Control (CDC) guidelines recommend schools use a coordinated health approach to support healthy eating and physical activity. This study examines whether the number of healthy eating and physical activity programs and activities used by schools and their perceived success relate to students' health-related fitness. This observational study used data from the Healthy Zone Schools Program. Data (collected in 2017-2019) were inte…
Keeping children healthy during and after Covid-19 pandemic
Background The purpose of this study was to: 1) examine the maintenance of Physical Education and physical activity during the distance learning time, 2) determine the resources educators are utilizing to deliver PE curricula, and 3) understand the challenges experienced by educators during distance learning. Methods A survey was sent to a cohort of school-based fitness assessment software users. Respondents were largely school-based individuals …
Associations between gender, school socioeconomic status, and cardiorespiratory fitness among elementary and middle school students
Results suggest girls in Healthy Zone Schools have lower odds to meet aerobic capacity fitness standards than boys. Additionally, boys and girls in schools serving a greater percentage of economically disadvantaged students have lower odds to meet aerobic capacity fitness standards. Last, girls have even lower odds of meeting HFZ standard when attending a school serving a greater percentage of economically disadvantaged students. Thus, schools ne…
The combined effect of physical activity and sedentary behavior on subclinical atherosclerosis
Our results indicate that for Mexican Americans, there is a combined effect of sedentary behavior and physical activity on presence of carotid plaque. Participating in moderate physical activity is optimal for having lower levels of carotid plaque in addition to avoiding excessive levels of TV/movie sitting (≥3 h/day) and/or total sitting (≥8.5 h/day)
Examining the Validity, Reliability, and Measurement Invariance of the Social Support for Exercise Scale Among Spanish- and English-Language Hispanics
The Social Support for Exercise Subscales are commonly used among Hispanic populations. The aims of this study were to test the validity and reliability of the Spanish-language version of the Social Support for Exercise Subscales and test the invariance of the Spanish- and English-language versions. Data were from a subsample of Hispanic adults in the Cameron County Hispanic Cohort ( n = 1,447). A series of confirmatory factor analysis (CFA) mode…
