Examining Whether Exercise Preference and Tolerance Moderate the Within-Subject Association Between Physical Activity Intention and Next-Day Moderate to Vigorous Physical Activity.

Background: Physical activity (PA) intentions may predict future PA engagement, such that when intentions for PA are strong, an individual may be more likely to engage in PA compared with when intentions for PA are weak. However, intentions do not always translate into behavior, a phenomenon known as the intention-behavior gap. Individual differences in exercise preference (predisposition for high-intensity exercise) and tolerance (ability to continue exercising at higher intensity) may explain this gap.

Burden and Inattentive Responding in a 12-Month Intensive Longitudinal Study: Interview Study Among Young Adults.

Background: Intensive longitudinal data (ILD) collection methods have gained popularity in social and behavioral research as a tool to better understand behavior and experiences over time with reduced recall bias. Engaging participants in these studies over multiple months and ensuring high data quality are crucial but challenging due to the potential burden of repeated measurements. It is suspected that participants may engage in inattentive responding (IR) behavior to combat burden, but the processes underlying this behavior are unclear as previous studies have focused on the barriers to compliance rather than the barriers to providing high-quality data.

Feasibility and preliminary effects of the Fit2ThriveMB pilot physical activity promotion intervention on physical activity and patient reported outcomes in individuals with metastatic breast cancer.

Purpose: Physical activity research among patients with metastatic breast cancer (MBC) is limited. This study examined the feasibility and potential benefits of Fit2ThriveMB, a tailored mHealth intervention.

Methods: Insufficiently active individuals with MBC (n = 49) were randomized 1:1 to Fit2ThriveMB (Fit2ThriveMB app, Fitbit, and weekly coaching calls) or Healthy Lifestyle attention control (Cancer.

Long-term effects of the COVID-19 pandemic on children's physical activity and sedentary behavior.

Background: During the early months of the COVID-19 pandemic, decreases in physical activity (PA) and increases in sedentary behavior (SB) were reported among children in the United States (U.S.).

Legislation has Changed But Issues Remain: Provider Perceptions of Caring for People Who Use Cannabis During Pregnancy in Safety Net Health Settings, a Qualitative Pilot Study.

Objective: To identify perceptions of cannabis use and risk among maternal health providers who provide care for people who use cannabis during pregnancy in safety-net health settings.

Methods: Using qualitative, constructivist ground theory methods, we conducted semistructured remote interviews with 10 providers (2 midwives, 6 OB/GYN physicians, and 2 OB/GYN residents) in Southern California, United States, between March 15, 2022, and April 6, 2022. We selected participants through selective sampling using a convenience sample and snowball approach.

Motivational Profile as a Predictor of Physical Activity Among US Adults During the Early Months of the COVID-19 Pandemic: A Daily Diary Study.

This study used a daily diary approach to examine associations between day-level physical activity (PA) behavior, PA-specific motivational profile, and days since the COVID-19 national emergency declaration during the early months (April-June 2020) of the pandemic. A total of 468 US adults (Mage = 34.8 y, 79% female) participated in a 28-day smartphone-based daily diary study assessing PA.

Accelerometer-Based Physical Activity and Shape and Weight Concerns Among Youth With Overweight and Obesity: A Pilot Exploratory Ecological Momentary Assessment Study.

A bidirectional association between shape and weight concerns (SWC) and physical activity (PA) has been previously documented. This relationship may be particularly salient among youth with overweight/obesity, given that social marginalization of larger bodies has been associated with elevated SWC and barriers to PA. This pilot study explores reciprocal relationships between momentary SWC and accelerometer-assessed PA behavior.

Emotion regulation expectancies and smoking cessation factors: A daily diary study of California adults who smoke cigarettes during a practice quit attempt.

Significance: Cross-sectional studies have shown that greater cigarette smoking-related emotion regulation expectancies were associated with retrospectively reported withdrawal during prior quit attempts and greater barriers to cessation. Few studies have investigated the relationship of within-person daily emotion regulation expectancies to factors related to initiating and maintaining a brief quit attempt.

Methods: People living in California who smoked cigarettes daily (n = 220, 50 % female; 48.

Interactive associations between abstinence plans and romantic partner conflict and support with cigarette smoking.

Background: While most individuals who smoke cigarettes desire to quit, quit motivation can change daily and sustained abstinence is rarely achieved in quit attempts. Assessment of psychosocial factors that moderate associations between daily abstinence intentions and smoking behavior is necessary to inform effective cessation efforts.

Methods: A secondary analysis was conducted using data from a 28-day ecological momentary assessment study among individuals who smoke and who were not actively planning a long-term quit attempt (N = 81 individuals; N = 1585 days).

Investigating Microtemporal Processes Underlying Health Behavior Adoption and Maintenance: Protocol for an Intensive Longitudinal Observational Study.

Background: Young adulthood (ages 18-29 years) is marked by substantial weight gain, leading to increased lifetime risks of chronic diseases. Engaging in sufficient levels of physical activity and sleep, and limiting sedentary time are important contributors to the prevention of weight gain. Dual-process models of decision-making and behavior that delineate reflective (ie, deliberative, slow) and reactive (ie, automatic, fast) processes shed light on different mechanisms underlying the adoption versus maintenance of these energy-balance behaviors.

Day-level associations of physical activity and sedentary time in mother-child dyads across three years: a multi-wave longitudinal study using accelerometers.

Understanding associations between mothers' and children's physical activity and sedentary behavior on more fine-grained timescales can provide insights into real-time intervention opportunities. This study examined the extent to which mothers' and their children's device-measured moderate-to-vigorous physical activity (MVPA) and sedentary time (SDT) were associated at the day level during non-school time. Mother-child dyads (N = 193; baseline Mean ages = 40.

Examining Whether Physical Activity Location Choices Were Associated With Weekly Physical Activity Maintenance Across 13 Months of the COVID-19 Pandemic in Emerging Adults.

Background: Recent studies have shown potentially detrimental effects of the COVID-19 pandemic on physical activity (PA) in emerging adults (ages 18-29 y). However, studies that examined the effects of COVID-19 on PA location choices and maintenance for this age group remain limited. The current study investigated changes in PA location choices across 13 months during the pandemic and their associations with PA maintenance in this population.

Intensive Longitudinal Data Collection Using Microinteraction Ecological Momentary Assessment: Pilot and Preliminary Results.

Background: Ecological momentary assessment (EMA) uses mobile technology to enable in situ self-report data collection on behaviors and states. In a typical EMA study, participants are prompted several times a day to answer sets of multiple-choice questions. Although the repeated nature of EMA reduces recall bias, it may induce participation burden.

Dyadic Effects of Pokémon GO on Physical Activity and Sedentary Behavior in Mothers and Children.

Family-based mobile health applications may be an opportunity to increase children's physical activity (PA) levels. Researchers have highlighted Pokémon GO as a potential model for future PA interventions as it integrates PA with social gamification. This study provides descriptive data on Pokémon GO usage among mothers and their children and examines differences in moderate to vigorous PA (MVPA) over time among individuals playing Pokémon GO compared to non-players using a dyadic subsample from a three-year longitudinal study.

Examining the day-level impact of physical activity on affect during the early months of the COVID-19 pandemic: An ecological momentary assessment study.

Engaging in physical activity (PA) may be a promising approach to mitigate the effects of the COVID-19 pandemic and related restrictions on daily affect. The study used ecological momentary assessment (EMA) to examine the within-subject associations of day-level PA with same-day evening affect. Interactions between daily PA and overall stress related to COVID-19 predicting evening affect were also examined.

Using a daily diary approach to examine the early effects of COVID-19 on daily physical activity bouts and contexts among residents of Colorado and California.

COVID-19 restrictions may prevent adults from achieving sufficient physical activity (PA) and may affect PA context. This study examined the early effects of COVID-19 on daily PA bouts and contexts during April-June 2020 using a daily diary approach. Adults (N = 390) completed daily diary surveys for 28 days assessing number of PA bouts and social (e.

Interactions among Reward Sensitivity and Fast-Food Access on Healthy Eating Index Scores in Adolescents: A Cross-Sectional Study.

Food cues in the environment may contribute to obesity as the consumption of unhealthy foods may reinforce reward pathways in the brain. To understand how person-level differences in reward sensitivity may be associated with diet quality, this study aimed to examine the moderating role of the availability of fast food in the environment on the relationship between reward sensitivity and diet quality in adolescents. Participants ( = 152; 55% female; Mage: 12.

Interactions between daily abstinence plans and approach/avoidance motivation on cigarette smoking in pre-quit smokers.

Enhancing motivation to quit among smokers who are not ready for cessation is a key component of several interventions. However, there is a dearth of empirical data about motivational factors and smoking behavior among pre-quit smokers. Here, we examined interactions between approach/avoidance goal motivations and daily abstinence plan (i.

The COMET study: Examining the effects of COVID-19-related perceived stress on Los Angeles Mothers' dysregulated eating behaviors, child feeding practices, and body mass index.

The COVID-19 pandemic and associated restrictions and mandates have had pronounced implications on the well-being of individuals. This study conducted exploratory analyses of the relationship between COVID-19-related life changes and COVID-19-related perceived stress and associations between COVID-19-related perceived stress and dysregulated maternal eating behaviors, child feeding practices, and body mass index (BMI) in Los Angeles mothers. Mothers (M = 37.

Impact of self-efficacy on daily intention to not smoke.

Background: To improve cessation interventions, it is necessary to understand the factors associated with daily motivation to not smoke. One hypothesized factor is self-efficacy; however, there has been a lack of evidence investigating self-efficacy as a dynamic construct.

Methods: This study examined the influence of baseline and daily self-efficacy on setting daily abstinence plans in pre-quit smokers and successful plans.

Momentary and personal characteristics predicting maternal fruit and vegetable preparation for children using ecological momentary assessment.

A large body of literature on child-focused research regarding healthy eating within the family context has focused on behavioral management strategies, such as reinforcement, or parental modeling through personal intake or encouragement. However, food preparation behaviors among mothers have been understudied. Also unknown is how maternal food preparation behaviors vary across population subgroups and contexts.

Discrimination and Eating Disorder Psychopathology: A Meta-Analysis.

Eating disorders occur in diverse populations, and discrimination may be a specific factor that is related to higher eating disorder psychopathology among marginalized individuals. To evaluate the current evidence on this topic, a meta-analysis was used to quantitatively synthesize the literature on discrimination and eating disorder psychopathology across a heterogeneous range of studies. Searches were conducted in peer-reviewed journals and accessible unpublished dissertations of all years through January 2020.

Bi-Directional Associations Between Real-Time Affect and Physical Activity in Weight-Discordant Siblings.

Unlabelled: Pediatric obesity confers increased risk for a host of negative psychological and physical health consequences and is reliably linked to low levels of physical activity. Affective antecedents and consequences of physical activity are thought to be important for the development and maintenance of such behavior, though research examining these associations in youth across the weight spectrum remains limited.

Objective: This study examined bi-directional associations between affect and physical activity (i.

Early effects of the COVID-19 pandemic on physical activity locations and behaviors in adults living in the United States.

COVID-19 restrictions and social-distancing may inhibit adults from attaining recommended levels of physical activity. This study examined early impact of COVID-19 pandemic on physical activity in adults during the first two months of restrictions in the U.S.
