Objectives Therapeutic virtual reality (VR) has emerged as an effective, drug-free tool for pain management, but there is a lack of randomized, controlled data evaluating its effectiveness in hospitalized patients. We sought to measure the impact on-demand VR versus "health and wellness" television programming Methods performed prospective, comparative trial patients with average score ≥3 out 10 points. Patients experimental group received library 21 experiences administered using Samsung...
Despite the known advantages of objective physical activity monitors (e.g., accelerometers), these devices have high rates non-wear, which leads to missing data. Objective are also unable capture valuable contextual information about behavior. Adolescents recruited into surveillance and intervention studies will increasingly smartphones, miniature computers with built-in motion sensors.This paper describes design development a smartphone application ("app") called Mobile Teen that combines...
Background: Objective physical activity monitors (eg, accelerometers) have high rates of nonwear and do not provide contextual information about behavior. Objective: This study tested performance value a mobile phone app that combined objective real-time self-report methods to measure using sensor-informed context-sensitive ecological momentary assessment (CS-EMA). Methods: The was programmed prompt CS-EMA surveys immediately after 3 types events detected by the phone's built-in motion...
This study used time-varying effect modeling to examine time-of-day differences in how behavioral cognitions predict subsequent physical activity (PA). Adults (N = 116) participated three 4-day "bursts" of ecological momentary assessment (EMA). Participants were prompted with eight EMA questionnaires per day assessing (i.e., intentions, self-efficacy, outcome expectations) and wore an accelerometer during waking hours. Subsequent PA was operationalized as accelerometer-derived minutes...
We examined the acute bidirectional relationships between affective states and moderate-to-vigorous physical activity (MVPA) or sedentary behavior (SB) in children, whether perceived stress moderates these associations.
Telemedicine has been used to remotely diagnose and treat patients, yet previously applied telemonitoring approaches have fraught with adherence issues. The primary goal of this study was evaluate the rates using a consumer-grade continuous-time heart rate activity tracker in mid-risk cardiovascular patient population. As secondary analysis, we show ability utilize information provided by device identify about patient's state correlating patient-reported outcome survey scores. We showed that...
Research attempting to elucidate physical activity (PA) intention-behavior relations has focused on differences in long-term behavior forecasting between people. However, regular PA requires a repeated performance daily or within-daily basis. An empirical case study application is presented using intensive longitudinal data from of adults (a) describe the extent which short-term coupling occurs and (b) explore time-varying predictors intention formation coupling. Adults (n = 116)...
The current study used a novel real-time data capture strategy, ecological momentary assessment (EMA), to examine whether within-day variability in stress and context leads exacerbations asthma symptomatology the everyday lives of ethnic minority adolescents. Low-income Hispanic adolescents ( N = 20; 7th-12th grade; 54% male) with chronic completed 7 days EMA on smartphones, an average five assessments per day during non-school time. surveys queried about where (e.g., home, outdoors) whom...
Objective Few studies have examined ankylosing spondylitis ( AS ) patients’ concerns about and perceptions of biologic therapies, apart from traditional surveys. In this study, we used social media data to examine the knowledge, attitudes, beliefs patients regarding therapies. Methods We collected posts published on 601 sites between January 1, 2016 April 26, 2017. each post, both an keyword a were mentioned. To explore themes within collection in unsupervised manner, latent Dirichlet...
The use of intensive sampling methods, such as ecological momentary assessment (EMA), is increasingly prominent in medical research. However, inferences from data are often limited to the subject-specific mean outcome and between-subject variance (i.e., random intercept), despite capability examine within-subject scale) associations between covariates slope). MixWILD (Mixed model analysis With Intensive Longitudinal Data) statistical software that tests effects subject-level parameters...
Abstract Objective To describe a configurable mobile health (mHealth) framework for integration of physiologic and environmental sensors to be used in studies focusing on the domain pediatric asthma. Materials Methods The Biomedical REAl-Time Health Evaluation (BREATHE) platform connects different data streams, contextualizing an individual’s symptoms daily activities over time understand asthma’s presentation its management. A smartwatch/smartphone combination serves as hub...
Background Stress may compromise parenting practices related to children's dietary intake, physical activity, and sedentary behavior.Purpose The current study used Ecological Momentary Assessment (EMA) examine microtemporal sequences underlying maternal stress subsequent weightrelated practices.Methods Mothers (n = 199) of children aged 8-12 years participated in two separate 7-day waves EMA with up eight randomly prompted surveys per day during nonschool time.EMA items assessed...
Ecological momentary assessment (EMA) is a real-time sampling strategy that may address limitations in health research, such as the inability to examine how processes unfold on daily basis. However, EMA studies are prone limited data availability due difficulties implementing sophisticated protocols and systematic non-compliance with prompts, resulting biased estimates statistical power. The objectives of this study were describe data, response patterns, analyze factors related prompt...
ABSTRACT Purpose The objective of this study was to quantify age-related changes in accelerometer-derived day-level physical activity and sedentary behavior pattern metrics (i.e., number, length, temporal dispersion bouts breaks) across 3 yr middle childhood. Differences by child sex weekend versus weekday were examined. Method Children ( N = 169, 54% female, 56% Hispanic; 8–12 old at enrollment) participated a longitudinal with six assessments yr. Day-level moderate-to-vigorous (MVPA; i.e.,...
Background: Exposure to air pollution is associated with acute pediatric asthma exacerbations, including reduced lung function, rescue medication usage, and increased symptoms; however, most studies are limited in investigating longitudinal changes these effects. This study aims investigate the effects of daily exposure on exacerbation risk using a repeated-measures design. Methods: We conducted panel 40 children aged 8–16 years moderate-to-severe asthma. deployed Biomedical REAI-Time Health...
Abstract Identifying vulnerable windows for a given problematic behavior and providing timely appropriate support are critical building an effective just-in-time (JIT) intervention behavioral change. We developed evaluated implementation intention (II) based, JIT cessation prototype to Asian American young adult smokers prevent lapses in their attempts real-time. examined how II reminder may during self-identified high-risk smoking situation (HRSS) as microtemporal process. also tested...
Abstract Objective To provide preliminary evidence in support of using ecological momentary assessment (EMA), a real-time data capture method involving repeated assessments, to measure dietary intake children by examining the concordance children’s reports through EMA and 24 h recall. Design Children completed eight days surveys, reporting on recent four pre-specified food categories (‘Fruits or Vegetables’, ‘Chips Fries’, ‘Pastries Sweets’, ‘Soda Energy Drinks’), two recalls during same...
Background: To address the limitations of retrospective self-reports activity, such as its susceptibility to recall bias, researchers have shifted toward collecting real-time activity data on mobile devices via ecological momentary assessment (EMA). Although EMA is becoming increasingly common, it not known how physical and sedentary behaviors relate objective measures or whether there are factors that may influence strength association between these two measures. Understanding relationship...
