How and why to follow best practices for testing mediation models with missing data.

Mediation models are often conducted in psychology to understand mechanisms and processes of change. However, current best practices for handling missing data in mediation models are not always used by researchers. Missing data methods, such as full information maximum likelihood (FIML) and multiple imputation (MI), are best practice methods of handling missing data.

A retrospective comparison of the biceps femoris long head muscle structure in athletes with and without hamstring strain injury history.

Introduction: Hamstring strain injuries (HSI) and re-injuries are endemic in high-speed running sports. The biceps femoris long head (BFlh) is the most frequently injured muscle among the hamstrings. Structural parameters of the hamstring muscle are stated to be susceptible to strain injuries at this location.

The Association Between Sexual Initiation and Membership in Dyadic Profiles of Perceived Shared Power.

There is scarce empirical evidence examining whether sexual initiation and power are associated with each other. Utilizing latent profile analyses, we examined in a nationally representative sample of US newlywed heterosexual couples (N = 1,948 couples) whether wives' and husbands' sexual initiation patterns and satisfaction with these patterns were associated with membership in different profiles of wives' and husbands' perceptions of shared relational power while accounting for both partner's satisfaction with sexual frequency. We found four profiles of wives' and husbands' perceptions of power.

Pharmacist Metrics in the Pediatric Intensive Care Unit: an Exploration of the Medication Regimen Complexity-Intensive Care Unit (MRC-ICU) Score.

The purpose of this study was to explore the MRC-ICU and other workload metrics in the pediatric ICU (PICU).

Methods: This study was a retrospective cohort of pediatric ICU patients admitted to a single institution -between February 2, 2022 - August 2, 2022.

Emotion-Driven Eating and Overeating Among Fourth Graders: The Roles of Body Image, Academic Achievement, and Peer and School Factors.

Background: Eating patterns such as breakfast consumption and fruit and vegetable intake have been associated with academic achievement and cognitive function.

Method: The purpose of this study was to learn more about psychological (emotion-driven eating) and behavioral (over-eating) eating patterns and motives, and the roles of body image, academic achievement (reading and math), and social supports (peer acceptance and school attachment), among 378 fourth-grade students (55% boys) from 14 classrooms across 6 schools within a large Midwestern urban area.

Results: Results were analyzed through a 2-group (male and female) path analysis.

Body satisfaction and disordered eating among male collegiate athletes: From point-prevalence to prediction.

Body satisfaction (BS) predicts lower levels of eating disorders and disordered eating behaviors (ED/DE) among female athletes, though recent research suggests similar effects for male athletes. However, research on male athletes' BS and ED/DE is limited, particularly in relation to times of transition, such as occurred in the months immediately following COVID-19 being recognized as a global pandemic. In this study, we surveyed 1975 male collegiate athletes in April/May 2020 to assess their body satisfaction and ED/DE symptomatology to determine prevalence and prediction between the two.

The Relationship of Resilience, Self-Compassion, and Social Support to Psychological Distress in Women Collegiate Athletes During COVID-19.

Given how COVID-19 had caused significant increases in collegiate athletes' psychological distress, we examined the extent to which such distress may have been ameliorated by the athletes' psychosocial resources (e.g., resilience).

Sleep disturbances and depression are bidirectionally associated among college student athletes across COVID-19 pandemic exposure classes.

College athletes may be vulnerable to sleep disturbances and depression during the COVID-19 pandemic as a result of large shifts in social and athletic obligations. In a national sample of college athletes, we examined the associations between sleep disturbances and depression across two timepoints, using COVID-19 exposure as a moderator. Data were collected from 2098 NCAA Division I, II, and III college athletes during two timepoints, from April 10 to May 23, and from August 4 to September 15, 2020.

The Influence of Instructor Behaviors and the Perceived Motivational Climate on Undergraduate Students' Experiences in College STEM Laboratories.

Biology laboratory instructors play a key role in creating an optimal environment where college students try hard and enjoy their classroom experiences. This study used achievement goal perspective theory to examine the influence of instructor behaviors on science, technology, engineering, and mathematics (STEM) students' perceptions of the motivational climate (caring, task, ego) and their adaptive (i.e.

Self-compassion, body satisfaction, and disordered eating symptoms in male collegiate athletes: A longitudinal analysis.

Male athletes are a subpopulation at risk for developing eating disorders and disordered eating concerns, primarily due to the presence of socioculturally-based factors, including body dissatisfaction. Self-compassion may alleviate this risk by improving body satisfaction. To date, no study has examined longitudinally self-compassion's effect on body satisfaction and, ultimately, disordered eating in male athletes.

Drinking among college student athletes during the COVID-19 pandemic.

To investigate demographics, sport type, athletic identity, and COVID-19 sport season cancelation in relation to alcohol consumption among college student athletes shortly after the pandemic emerged. College student athletes recruited from U.S.

Design, Setting, And Participants: This retrospective cohort study included patients in a tertiary-care pediatric hospital system who had MIS-C per the Centers for Disease Control and Prevention case definition during the period March 2020 to February 2021.

A Model of Perfectionism, Moral Disengagement, Altruism, and Antisocial and Prosocial Behaviors in Wheelchair Athletes.

Two forms of perfectionism were examined in the present study to see whether they predicted prosocial and antisocial behaviors in sport through moral disengagement and altruism in a sample of 327 wheelchair basketball and rugby athletes (M = 33.57 years, SD = 10.51; 83% male).

College Student-athletes' COVID-19 Worry and Psychological Distress Differed by Gender, Race, and Exposure to COVID-19-related Events.

Purpose: The purpose of this study was to determine the prevalence of National Collegiate Athletic Association (NCAA) student-athletes' exposure to COVID-19-related events (e.g., canceled season, diagnosed with COVID) and their psychological distress in April/May 2020.

Development of a School Health Policy Implementation Survey: A Delphi Study.

Data on school health policy implementation are limited due to the absence of a validated measurement tool. The purpose of this study was to create and pilot a school health policy implementation survey. A modified, four-round Delphi process was used to achieve consensus on content and format of the survey.

Nutrition Supports Deconstructed and Disrupted: An Evaluation of a Multilevel School-Based Intervention during the Time of COVID.

The Best Food Forward (BFF) project aims to provide multiple nutrition supports and interventions to improve family food security (FS) and health outcomes associated with FS within two metropolitan school districts. A quasi-experimental time-series design guided a multilevel evaluation for BFF through surveys, biometric screenings, focus groups, and observations among a random sample of caregiver-child dyads. FS, utilization of school meal programs, and nutrition behaviors were observed and analyzed at three time points: preintervention, postintervention pre-COVID-19, and postintervention post-COVID-19.

Predicting Breastfeeding Intentions: A Test and Extension of the Theory of Normative Social Behavior with African American Social Identity.

Breastfeeding is a health promoting social behavior but statistics suggest a persistent disparity of lower rates among African American mothers. The Theory of Normative Social Behavior (TNSB) explains when and how norms influence behaviors, but has produced inconsistent results with respect to proposed moderators group identity and injunctive norms (IN), limiting its predictive value in diverse cultural groups. Cultural norms are one of many influences on breastfeeding behaviors, yet little is known about their mechanisms of influence.

Severe acute respiratory syndrome coronavirus 2 infection and critically ill children.

Purpose Of Review: Amidst an ongoing pandemic, the delineation of the pediatric consequence of infection from the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) virus is emerging. This review summarizes available pediatric data and covers the aspects of epidemiology, critical illness with acute infection [coronavirus disease 2019 (COVID-19)], the discovered multi-inflammatory syndrome in children (MIS-C), and management options.

Recent Findings: The available data from the source of the initial viral transmission and then through Europe, Africa, and the Western Hemisphere identifies important aspects of the SARS-CoV2 pandemic: 1) Pediatric infection occurs commonly, is likely underestimated, and transmission patterns remain incompletely described, 2) Pediatric patients suffer multiple end-organ injuries but COVID-19 is not the same prevalence in terms of severity as in adults, 3) MIS-C is a novel and life-threatening manifestation of exposure to the virus, 4) Management using a combination of supportive care, standard practice intensive care management, and anti-inflammatory agents is associated with recovery, 5) Long-term sequelae of viral exposure is unknown at this time.

"Difficult to Sedate": Successful Implementation of a Benzodiazepine-Sparing Analgosedation-Protocol in Mechanically Ventilated Children.

We sought to evaluate the success rate of a benzodiazepine-sparing analgosedation protocol (ASP) in mechanically ventilated children and determine the effect of compliance with ASP on in-hospital outcome measures. In this single center study from a quaternary pediatric intensive care unit, our objective was to evaluate the ASP protocol, which included opiate and dexmedetomidine infusions and was used as first-line sedation for all intubated patients. In this study we included 424 patients.

Effects of a Comprehensive School Health Program on Elementary Student Academic Achievement.

Background: Improving the academic achievement of youth in the United States is an area of interest and a critical indicator of the future success of the youth. The purpose of this study was to examine the impact of a comprehensive school physical activity and healthy eating program on 5th-grade students' academic achievement, specifically reading and math.

Methods: Overall, 628 (intervention: 377, 54% girls; comparison: 251, 49% girls) 5th-grade children participated across the 6 schools in a year-long comprehensive health intervention, completing curriculum-based academic achievement measures at 2 time-points.

A novel item-allocation procedure for the three-form planned missing data design.

We propose a new method of constructing questionnaire forms in the three-form planned missing data design (PMDD). The (RIA) procedure that we propose promises to dramatically simplify the process of implementing three-form PMDDs without compromising statistical performance. Our method is a stochastic approximation to the currently recommended approach of deterministically spreading a scale's items across the X-, A-, B-, and C-blocks when allocating the items in a three-form design.

Knowledge, Attitudes, Self-Efficacy, and Healthy Eating Behavior Among Children: Results From the Building Healthy Communities Trial.

. Increased knowledge, attitudes, and beliefs about a topic and behavioral capability and self-efficacy for healthy eating are often a precursor to behavior change. The purpose of this study is to determine the effectiveness of the multicomponent school-based program on children's healthy eating knowledge, attitudes, and self-efficacy for healthy eating, and on their eating habits over time.

Building healthy communities: A comprehensive school health program to prevent obesity in elementary schools.

Obesity among children is highly prevalent and can lead to risk factors for chronic disease in adulthood. Key organizations have called on schools to play a larger role by increasing children's physical activity and nutrition by adopting an overall culture of health. This study examined the impact of a socioecological theory driven school-wide nutrition and physical activity intervention on 5th graders' central adiposity and obesity level.
