Physical Activity Measurement Reactivity Among Midlife Adults With Elevated Risk for Cardiovascular Disease: Protocol for Coordinated Analyses Across Six Studies

Physical Activity Measurement Reactivity Among Midlife Adults With Elevated Risk for Cardiovascular Disease: Protocol for Coordinated Analyses Across Six Studies

PA measurement reactivity has been observed in a subset of studies to date [25,29-31], and some PA researchers consider reactivity a critical source of bias that warrants increased attention and mitigating actions, such as requiring extra days of observation to get used to the PA monitor or removing the first 1-2 days of PA observation from analyses [30].

Preventing Premature Pre-Exposure Prophylaxis Discontinuation and Sexually Transmitted Infections Among Men Who Have Sex With Men (Project PEACH): Protocol for a Prospective Cohort Study

Preventing Premature Pre-Exposure Prophylaxis Discontinuation and Sexually Transmitted Infections Among Men Who Have Sex With Men (Project PEACH): Protocol for a Prospective Cohort Study

The enrollment visit consisted of an informed consent process, a computer-assisted self-interview behavioral survey, HIV and STI testing, training on using the study app, and a counseling session to include pre- and posttest HIV prevention information and a discussion about Pr EP and STI PEP options. Participants who completed an enrollment visit were compensated US $125 regardless of whether they subsequently participated in the study.

A Conversational Agent Using Natural Language Processing for Postpartum Care for New Mothers: Development and Engagement Analysis

A Conversational Agent Using Natural Language Processing for Postpartum Care for New Mothers: Development and Engagement Analysis

Given the complexity and individualized needs of the postpartum patient we postulated that a conversational agent using NLP might be a good solution and be acceptable to this population. We envisioned a 24/7 available SMS text message—based support program that interpreted patients’ postpartum concerns, responded in real sentences and could also alert clinicians in real time when appropriate.

Developing Digital Mental Health Tools With Culturally Diverse Parents and Young People: Qualitative User-Centered Design Study

Developing Digital Mental Health Tools With Culturally Diverse Parents and Young People: Qualitative User-Centered Design Study

Using a user experience technique traditionally referred to as a cognitive walk-through, we aimed to explore participants’ emotional responses as they engaged with the interface [84,85]. We adapted a walk-through user testing methodology [86] and created a 6-page emotional walk-through booklet (Figure 3) that was distributed to participants along with a link to a prototype of the web-based mental health screening platform intended for national deployment in the near future.

The Comprehensive Adaptive Multisite Prevention of University Student Suicide Trial: Protocol for a Randomized Controlled Trial

The Comprehensive Adaptive Multisite Prevention of University Student Suicide Trial: Protocol for a Randomized Controlled Trial

A SMART is a type of factorial design used to develop and optimize adaptive interventions by studying treatments in a sequential manner [17-19]. In a SMART, participants can receive multiple interventions over time depending on their response to previous treatments and may be randomized more than once. For example, if a participant does not sufficiently respond to an initial course of care that they were initially randomized to receive, they might be rerandomized to one of several second-line treatments.

Validation of an Adaptive Assessment of Executive Functions (Adaptive Cognitive Evaluation-Explorer): Longitudinal and Cross-Sectional Analyses of Cognitive Task Performance

Validation of an Adaptive Assessment of Executive Functions (Adaptive Cognitive Evaluation-Explorer): Longitudinal and Cross-Sectional Analyses of Cognitive Task Performance

Therefore, we argue that this method, in combination with a community detection algorithm, allows for a more novel approach to answering the question of how EF tasks group together to form constructs. Adaptive Cognitive Evaluation-Explorer (ACE-X) is a research tool developed at Neuroscape, a center in the Department of Neurology at the University of California, San Francisco, to assess the 3 facets of cognitive control (attention, working memory, and cognitive flexibility) [16,17].

Trustworthiness of Web-Based Pharmacy Apps in Pakistan Based on the Mobile App Rating Scale: Content Analysis and Quality Evaluation

Trustworthiness of Web-Based Pharmacy Apps in Pakistan Based on the Mobile App Rating Scale: Content Analysis and Quality Evaluation

Over the past decade, the internet has evolved into a primary source of knowledge for many individuals. The demand for purchasing things online, including medications, has experienced a parallel surge [1]. In the last few years, a discernible transformation has occurred within the pharmacy industry, whereby a considerable number of conventional pharmacies have adopted e-commerce platforms.

Consumer-Grade Neurofeedback With Mindfulness Meditation: Meta-Analysis

Consumer-Grade Neurofeedback With Mindfulness Meditation: Meta-Analysis

This has led to a proliferation of technology supported mindfulness [8-13]. Neurofeedback may be one method of supporting or enhancing mindfulness learning [12,32,33]. Neurofeedback consists of measuring brain signals during a task and relaying those signals (targets) to the participant. The participant may learn with repeated practice to modulate the target, with beneficial outcomes.

Development of a GPT-4–Powered Virtual Simulated Patient and Communication Training Platform for Medical Students to Practice Discussing Abnormal Mammogram Results With Patients: Multiphase Study

Development of a GPT-4–Powered Virtual Simulated Patient and Communication Training Platform for Medical Students to Practice Discussing Abnormal Mammogram Results With Patients: Multiphase Study

We do this in the context of a GPT-4–based VSP that we developed for a medical simulation study. The learner, taking on the role of a primary care physician (PCP), simulates a phone call with the VSP to discuss an abnormal screening mammogram result that requires a patient to schedule a biopsy.
