Intrinsic motivation for physical activity, healthy eating, and self-weighing in association with corresponding behaviors in early pregnancy.

Healthy lifestyle behaviors influence maternal cardiovascular health, but motivation for them in pregnancy is poorly understood. We examined whether intrinsic motivation (assessed on 5-point scales for each behavior) is associated with three lifestyle behaviors in early pregnancy: physical activity, by intensity level; healthy eating, quantified with the Alternate Healthy Eating Index for Pregnancy (AHEI-P); and weight self-monitoring, a standard weight management technique. Participants in the Northern California Pregnancy, Lifestyle and Environment Study (PETALS) population-based cohort completed validated surveys in early pregnancy (2017-18;  = 472; 22 % Asian, 6 % Black, 30 % Hispanic, 13 % multiracial, 30 % White).

Momentary Influences on Self-Regulation in Two Populations With Health Risk Behaviors: Adults Who Smoke and Adults Who Are Overweight and Have Binge-Eating Disorder.

Introduction: Self-regulation has been implicated in health risk behaviors and is a target of many health behavior interventions. Despite most prior research focusing on self-regulation as an individual-level trait, we hypothesize that self-regulation is a time-varying mechanism of health and risk behavior that may be influenced by momentary contexts to a substantial degree. Because most health behaviors (e.

Casting New Light on Statistical Power: An Illuminating Analogy and Strategies to Avoid Underpowered Trials.

Current standards for methodological rigor and trial reporting underscore the critical issue of statistical power. Still, the chance of detecting most effects reported in randomized controlled trials in medicine and other disciplines is currently lower than winning a toss of a fair coin. Here we propose that investigators who retain a practical understanding of how statistical power works can proactively avoid the potentially devastating consequences of underpowered trials.

Downstream funding success of early career researchers for resubmitted versus new applications: A matched cohort.

Background: Early career researchers face a hypercompetitive funding environment. To help identify effective intervention strategies for early career researchers, we examined whether first-time NIH R01 applicants who resubmitted their original, unfunded R01 application were more successful at obtaining any R01 funding within 3 and 5 years than original, unfunded applicants who submitted new NIH applications, and we examined whether underrepresented minority (URM) applicants differentially benefited from resubmission. Our observational study is consistent with an NIH working group's recommendations to develop interventions to encourage resubmission.

Methods-Motivational Interviewing Approach for Enhanced Retention and Attendance.

Introduction: Suboptimal and differential participant engagement in randomized trials-including retention at primary outcome assessments and attendance at intervention sessions-undermines rigor, internal validity, and trial conclusions.

Methods: First, this study describes Methods-Motivational Interviewing approach and strategies for implementation. This approach engages potential participants before randomization through interactive, prerequisite orientation sessions that illustrate the scientific rationale behind trial methods in accessible language and use motivational interviewing to diffuse ambivalence about participation.

Introducing the MAVEN Leadership Training Initiative to diversify the scientific workforce.

Addressing gender and racial-ethnic disparities at all career stages is a priority for the research community. In this article, we focus on efforts to encourage mid-career women, particularly women of color, to move into leadership positions in science and science policy. We highlight the need to strengthen leadership skills for the critical period immediately following promotion to associate/tenured professor - when formal career development efforts taper off while institutional demands escalate - and describe a program called MAVEN that has been designed to teach leadership skills to mid-career women scientists, particularly those from underrepresented groups.

Challenges and Opportunities for the Prevention and Treatment of Cardiovascular Disease Among Young Adults: Report From a National Heart, Lung, and Blood Institute Working Group.

Improvements in cardiovascular disease (CVD) rates among young adults in the past 2 decades have been offset by increasing racial/ethnic and gender disparities, persistence of unhealthy lifestyle habits, overweight and obesity, and other CVD risk factors. To enhance the promotion of cardiovascular health among young adults 18 to 39 years old, the medical and broader public health community must understand the biological, interpersonal, and behavioral features of this life stage. Therefore, the National Heart, Lung, and Blood Institute, with support from the Office of Behavioral and Social Science Research, convened a 2-day workshop in Bethesda, Maryland, in September 2017 to identify research challenges and opportunities related to the cardiovascular health of young adults.

Interactive group-based orientation sessions: A method to improve adherence and retention in pragmatic clinical trials.

Background: Intervention adherence and trial retention are challenging for clinical trials testing intensive behavioral interventions. Operational constraints or trial designs may preclude using effective retention strategies such as financial incentives. We examined whether implementing pre-enrollment orientation sessions was associated with higher intervention adherence and retention in a pragmatic clinical trial.

Effects of a methodological infographic on research participants' knowledge, transparency, and trust.

Objective: Given participants' research literacy is essential for clinical trial participation, evidence-based strategies are needed that improve literacy and easily accessed online. We tested whether an infographic letter-that illustrated how dropouts can distort study conclusions-improved participant knowledge about the impact of dropouts relative to a control letter.

Method: In three distinct online samples purposely recruited to assess reproducibility, young ethnically diverse adults were randomized to read an infographic letter or control letter in a hypothetical scenario.

The ASIBS Short Course: A unique strategy for increasing statistical competency of junior investigators in academic medicine.

As clinical researchers at academic medical institutions across the United States increasingly manage complex clinical databases and registries, they often lack the statistical expertise to utilize the data for research purposes. This statistical inadequacy prevents junior investigators from disseminating clinical findings in peer-reviewed journals and from obtaining research funding, thereby hindering their potential for promotion. Underrepresented minorities, in particular, confront unique challenges as clinical investigators stemming from a lack of methodologically rigorous research training in their graduate medical education.

The Relationship Between the Stanford Leisure-Time Activity Categorical Item and the Godin Leisure-Time Exercise Questionnaire Among Rural Intervention Participants of Varying Health Literacy Status.

Background: A pragmatic, self-reported physical activity measure is needed for individuals of varying health literacy status.

Methods: This study is a secondary analysis of a 6-month behavioral intervention for rural Appalachian adults developed using health literacy strategies. We examined the relationship and responsiveness of the Stanford Leisure-Time Activity Categorical Item (L-Cat) and adapted Godin Leisure-Time Exercise Questionnaire (GLTEQ) and determined if baseline health literacy status moderates intervention effects.

Applying novel technologies and methods to inform the ontology of self-regulation.

Self-regulation is a broad construct representing the general ability to recruit cognitive, motivational and emotional resources to achieve long-term goals. This construct has been implicated in a host of health-risk behaviors, and is a promising target for fostering beneficial behavior change. Despite its clear importance, the behavioral, psychological and neural components of self-regulation remain poorly understood, which contributes to theoretical inconsistencies and hinders maximally effective intervention development.

Impact of a Genetic Risk Score for Coronary Artery Disease on Reducing Cardiovascular Risk: A Pilot Randomized Controlled Study.

Purpose: We tested whether providing a genetic risk score (GRS) for coronary artery disease (CAD) would serve as a motivator to improve adherence to risk-reducing strategies.

Methods: We randomized 94 participants with at least moderate risk of CAD to receive standard-of-care with ( = 49) or without ( = 45) their GRS at a subsequent 3-month follow-up visit. Our primary outcome was change in low density lipoprotein cholesterol (LDL-C) between the 3- and 6-month follow-up visits (ΔLDL-C).

A Simulation Modeling Framework to Optimize Programs Using Financial Incentives to Motivate Health Behavior Change.

Introduction: While increasingly popular among mid- to large-size employers, using financial incentives to induce health behavior change among employees has been controversial, in part due to poor quality and generalizability of studies to date. Thus, fundamental questions have been left unanswered: To generate positive economic returns on investment, what level of incentive should be offered for any given type of incentive program and among which employees?

Methods: We constructed a novel modeling framework that systematically identifies how to optimize marginal return on investment from programs incentivizing behavior change by integrating commonly collected data on health behaviors and associated costs. We integrated "demand curves" capturing individual differences in response to any given incentive with employee demographic and risk factor data.

Outreach to diversify clinical trial participation: A randomized recruitment study.

Background/aims: Racial and ethnic minorities remain underrepresented in clinical research, yet few recruitment strategies have been rigorously evaluated.

Methods: We experimentally tested whether targeted recruitment letters acknowledging diabetes health disparities and health risks specific to recipients' racial/ethnic group improved two metrics of trial participation: willingness to be screened and enrollment. This experiment was efficiently nested within a randomized clinical trial examining a preventive lifestyle intervention among women at high risk for diabetes.

Promoting healthy weight with "stability skills first": a randomized trial.

Objective: Although behavioral weight-loss interventions produce short-term weight loss, long-term maintenance remains elusive. This randomized trial examined whether learning a novel set of "stability skills" before losing weight improved long-term weight management. Stability skills were designed to optimize individuals' current satisfaction with lifestyle and self-regulatory habits while requiring the minimum effort and attention necessary.

Minority recruitment into clinical trials: experimental findings and practical implications.

Racial and ethnic minorities in the US suffer disproportionately from obesity and related comorbidities, yet remain underrepresented in health research. To date, research on practical strategies to improve minority reach and recruitment into clinical trials is primarily descriptive rather than experimental. Within a randomized behavioral weight management trial for obese women, this recruitment experiment examined whether two characteristics of direct mail letters, an ethnically-targeted statement and personalization, increased the response rate among minority women.

Social support for healthy behaviors: scale psychometrics and prediction of weight loss among women in a behavioral program.

Social support could be a powerful weight-loss treatment moderator or mediator but is rarely assessed. We assessed the psychometric properties, initial levels, and predictive validity of a measure of perceived social support and sabotage from friends and family for healthy eating and physical activity (eight subscales). Overweight/obese women randomized to one of two 6-month, group-based behavioral weight-loss programs (N = 267; mean BMI 32.

Practices associated with weight loss versus weight-loss maintenance results of a national survey.

Background: Few studies have examined the weight-control practices that promote weight loss and weight-loss maintenance in the same sample.

Purpose: To examine whether the weight control practices associated with weight loss differ from those associated with weight-loss maintenance.

Methods: Cross-sectional survey of a random sample of 1165 U.

Outcome expectations and realizations as predictors of weight regain among dieters.

This prospective study tested whether (a) baseline outcome expectations regarding the benefits of a weight-loss diet, (b) 6-month outcome realizations regarding perceived benefits actually experienced, and/or (c) the interaction between them predicted 6-12-month weight regain among overweight/obese women randomized to one of four popular weight-loss diets (N=311). Positive 6-month realizations regarding improvements in physical shape and appearance predicted less 6-12-month weight regain among Atkins diet participants only (n=70), controlling for baseline expectations, the expectations-realization interaction, and initial weight loss. Atkins participants displayed three distinct patterns of regain based on levels of 6-month realizations and initial weight loss.

How and why criteria defining moderators and mediators differ between the Baron & Kenny and MacArthur approaches.

Objective: In recognition of the increasingly important role of moderators and mediators in clinical research, clear definitions are sought of the two terms to avoid inconsistent, ambiguous, and possibly misleading results across clinical research studies.

Design: The criteria used to define moderators and mediators proposed by the Baron & Kenny approach, which have been long used in social/behavioral research, are directly compared to the criteria proposed by the recent MacArthur approach, which modified the Baron & Kenny criteria.

Results: After clarifying the differences in criteria between approaches, the rationale for the modifications is clarified and the implications for the design and interpretation of future studies considered.

The Jade Ribbon Campaign: a model program for community outreach and education to prevent liver cancer in Asian Americans.

The Jade Ribbon Campaign (JRC) is a culturally targeted, community-based outreach program to promote the prevention, early detection, and management of chronic hepatitis B virus (HBV) infection and liver cancer among Asian Americans. In 2001, 476 Chinese American adults from the San Francisco Bay Area attended an HBV screening clinic and educational seminar. The prevalence of chronic HBV infection was 13%; only 8% of participants showed serologic evidence of protective antibody from prior vaccination.

Concerns about infertility risks among pediatric oncology patients and their parents.

Background: Given pediatric cancer patients are living into adulthood, parents and patients need to be informed about fertility-related side effects of their particular treatment.

Procedure: We surveyed 97 parents of pediatric patients of all ages as well as 37 adolescent patients of 14 years or older who were presented for care at the Lucile Packard Children's Hospital (LPCH) at the Stanford University Medical Center. We estimated the potential infertility risk (low, intermediate, and high) based on the child's treatment regimen.
