Using Video Cameras to Assess Physical Activity and Other Well-Being Behaviors in Urban Environments: Feasibility, Reliability, and Participant Reactivity Studies

Using Video Cameras to Assess Physical Activity and Other Well-Being Behaviors in Urban Environments: Feasibility, Reliability, and Participant Reactivity Studies

A fundamental weakness of the evidence base is a reliance on self-report measures, most commonly surveys, which are susceptible to issues such as recall bias [5], measurement reactivity [6], and low response rates [7]. For example, survey response rates as low as 14% are not uncommon in physical activity research in this area [7], increasing the risk of selection bias. Another commonly used method involves infrared sensors, which offer a low-cost solution for monitoring footfall over long periods of time.

Artificial Intelligence Applications to Measure Food and Nutrient Intakes: Scoping Review

Artificial Intelligence Applications to Measure Food and Nutrient Intakes: Scoping Review

Given these attributes, AI emerges as a promising candidate to revolutionize the landscape of food and nutrient intake measurement. While numerous reviews have covered objective measures of dietary intake, our review specifically focuses on the application of AI technologies in this field. This scoping review provides a comprehensive synthesis of recent advancements, highlights the unique challenges faced by AI methodologies, and identifies critical gaps that future research should address.

Measuring Technology-Facilitated Sexual Violence and Abuse in the Chinese Context: Development Study and Content Validity Analysis

Measuring Technology-Facilitated Sexual Violence and Abuse in the Chinese Context: Development Study and Content Validity Analysis

Therefore, the development of a comprehensive, unified, and culturally sensitive measurement of TFSVA is needed. Although the concepts of TFSVA are not well defined, TFSVA in this study refers to any form of sexual violence or harassment through the misuse of digital technologies [12]. The overall goal of this formative work is to develop a TFSVA measurement with sound content validity in the Chinese context.

Raw Photoplethysmography as an Enhancement for Research-Grade Wearable Activity Monitors

Raw Photoplethysmography as an Enhancement for Research-Grade Wearable Activity Monitors

Successful innovation will likely entail novel measurement paradigms, rather than incremental improvements on current techniques [6]. One of the most promising and underexplored paradigms is to integrate data from multiple types of sensors, rather than the traditional use of only accelerometer sensors [7,8]. Photoplethysmography (PPG) is an optical technology that may have potential to enhance physical activity measurement when combined with established inertial sensors (accelerometers and gyroscopes) [9].

Clinician-Prioritized Measures to Use in a Remote Concussion Assessment: Delphi Study

Clinician-Prioritized Measures to Use in a Remote Concussion Assessment: Delphi Study

Smooth pursuits, saccades, VORb: feasible (most clinicians only complete these 3 components); need a well-placed camera VOR: feasible, but keeping at the right speed is a challenge; could use a metronome smartphone app Convergence: feasible, measurement is the barrier (unless having a person helping in-person) Visual motion sensitivity: feasible; however, safety concern if standing, need to have enough range (cannot do this in seated position unless while having a swivel chair) If solely using VOMS to capture

Electronic Health Literacy Scale-Web3.0 for Older Adults with Noncommunicable Diseases: Validation Study

Electronic Health Literacy Scale-Web3.0 for Older Adults with Noncommunicable Diseases: Validation Study

The reliabilities, validities, and measurement invariance of the e HLS-Web3.0 across gender and region have been supported in a previous study with young adults [33], whereas its psychometric properties remain unexplored in older adults, especially those living with NCDs.

The Conceptualization and Measurement of Research Impact in Primary Health Care: Protocol for a Rapid Scoping Review

The Conceptualization and Measurement of Research Impact in Primary Health Care: Protocol for a Rapid Scoping Review

Several scoping reviews, such as those conducted by Murphy et al [21] on measurement in rural PHC, Noorihekmat et al [22] on performance measurement frameworks in public health and primary care systems, and Akl et al [23] on faculty productivity in academic medical centers, have explored aspects of research productivity and measurement within health care.

Telehealth Evaluation in the United States: Protocol for a Scoping Review

Telehealth Evaluation in the United States: Protocol for a Scoping Review

During the COVID-19 pandemic, the National Quality Forum (NQF) updated its telehealth measurement development framework, initially created in 2017, through an environmental scan conducted in 2021 [18-20]. Despite the wealth of telehealth evaluation frameworks available, several critical questions remain unanswered.

Designing and Validating a Novel Method for Assessing Delay Discounting Associated With Health Behaviors: Ecological Momentary Assessment Study

Designing and Validating a Novel Method for Assessing Delay Discounting Associated With Health Behaviors: Ecological Momentary Assessment Study

Below, we describe traditional methods to measure delay discounting, the potential for ecological momentary assessment (EMA) to improve delay discounting measurement, and this study’s goals. Delay discounting rates quantify consequence devaluation (eg, a monetary reward’s devaluation) by delay [14]. One method to calculate delay discounting rates considers the devaluation process as a hyperbolic decay [15], as shown in equation 1.
