Objective: In the USA there are rising rates of obesity among children, at least in part due to unhealthy eating and physical inactivity. Implementing school-based health interventions with elementary school children focused on youth empowerment could lead to improved health environments and behaviours. The purpose of the present study was to examine elementary students’ perceptions of participating in a student-led school health improvement team. Empowerment theory guided the research, specifically the concept of including participants in programming to identify possible individual-level outcomes. Design: Qualitative research. Setting: One US elementary school formed a student-led school health improvement team, …
Comprehensive School Physical Activity Programs: Characteristics Of Trained Teachers, Erin E. Centeio, Heather Erwin, Darla M. Castelli
Comprehensive School Physical Activity Programs: Characteristics Of Trained Teachers, Erin E. Centeio, Heather Erwin, Darla M. Castelli
Kinesiology, Health and Sport Studies
As public health concerns about physical inactivity and childhood obesity continue to rise, researchers are calling for interventions that comprehensively lead to more opportunities to participate in physical activity (PA). The purpose of this study was to examine the characteristics and attitudes of trained physical education teachers during the implementation of a Comprehensive School Physical Activity Program at the elementary level. Using a collective case study design, interviews, observations, field notes, open-ended survey questions, and an online forum monitoring guided the interpretation of teacher perceptions and development of emergent themes. Qualitative data analysis was conducted for each individual teacher and …

he impact of Comprehensive School Physical Activity Programs (CSPAPs) on urban children’s, educators’, and parents’ physical activity (PA) is relatively unknown. The purpose of this study was to explore overall changes in student, educator, and parent PA after an 8-month CSPAP-based program. This longitudinal, exploratory study implemented a CSPAP in 20 urban elementary schools, with six randomized for research. In-school PA was measured prepost for all fourth grade students using accelerometers. Parent and educator PA was self-reported using the IPAQ. RM-ANOVAs revealed significant prepost increases in minutes of student MVPA (P < .001). Parents significantly increased PA (P < .01) and although educators’ reported change in PA, it was not statistically significant (P = .50). This study provides unique …
Pedestrian Head Protection During Car To Pedestrian Accidents: In The Event Of Primary Impact With Vehicle And Secondary Impact With Ground, Vishal Gupta
Wayne State University Dissertations
Current regulations for assessing pedestrian safety use a simplified test setup that ignores many real-world factors. In particular, the level of protection is assessed using a free-motion headform impacting the vehicle's hood at a fixed angle. As such, this test setup does not capture the effect due to the vehicle front-end profile, nor does it comprehend injury due to a possible secondary impact of the pedestrian's head with ground. This thesis aims to numerically simulate vehicle to pedestrian crashes to develop knowledge that may suggest ways to improve safety above and beyond the regulatory tests. Inputs to the simulations include …
Psychometric Support For The Ownership In Exercise And Empowerment In Exercise Scales, E. Whitney G. Moore, Mary D. Fry
Psychometric Support For The Ownership In Exercise And Empowerment In Exercise Scales, E. Whitney G. Moore, Mary D. Fry
Kinesiology, Health and Sport Studies
This study’s purpose was to examine the psychometric properties of two new scales developed to quantitatively measure participants’ ownership in exercise classes and empowerment with respect to exercise. These two outcome measures will compliment Achievement Goal Perspective Theory (AGPT) grounded research to better understand participants’ exercise experiences. College exercise class participants (N = 414; Mage = 21.25 years; 67% female) completed the survey during the last two weeks of a semester. Measurement invariance was assessed by a two-group (i.e., male and female) confirmatory factor analysis and used Mplus’ cluster option to account for the data’s nested nature. Strong …

We provide conceptual introductions to missingness mechanisms—missing completely at random (MCAR), missing at random (MAR), and missing not at random (MNAR)—and state-of-the-art methods of handling missing data—full-information maximum likelihood (FIML) and multiple imputation (MI)—followed by a discussion of planned missing designs: multiform questionnaire protocols, two-method measurement models, and wave-missing longitudinal designs. We reviewed 80 articles of empirical studies published in the 2012 issues of the Journal of Pediatric Psychology to present a picture of how adequately missing data are currently handled in this field. To illustrate the benefits of utilizing MI or FIML and incorporating planned missingness into study designs, …

Utilizing planned missing data (PMD) designs (ex. 3-form surveys) enables researchers to ask participants fewer questions during the data collection process. An important question, however, is just how few participants are needed to effectively employ planned missing data designs in research studies. This paper explores this question by using simulated three-form planned missing data to assess analytic model convergence, parameter estimate bias, standard error bias, mean squared error (MSE), and relative efficiency (RE).Three models were examined: a one-time point, cross-sectional model with 3 constructs; a two-time point model with 3 constructs at each time point; and a three-time point, mediation …
