Latinx and White Adolescents’ Preferences for Latinx-Targeted Celebrity and Noncelebrity Food Advertisements: Experimental Survey Study

Examining the influence of celebrity-endorsed food advertisements on the preferences of Latinx and White youth will enhance the field’s theoretical understanding of how ethnically targeted marketing uniquely affects Latinx youth, which can help inform practical implications on how public policies can address unhealthy food marketing that targets youth of color.

Characterizing Telehealth Barriers and Preferences to Promote Acceptable Implementation Strategies in Central Uganda: Multilevel Formative Evaluation

Indeed, very little is known about specific challenges and preferences for telehealth program implementation in African countries, particularly in Uganda [12]. This dearth of knowledge severely limits the ability to implement effective and appropriate telehealth solutions to improve health care access in Africa equitably.

The Paradigm Shift From Patient to Health Consumer: 20 Years of Value Assessment in Health

The Paradigm Shift From Patient to Health Consumer: 20 Years of Value Assessment in Health

Value assessment is performed by estimating a utility function that represents consumers’ preferences that are assumed to be complete and transitive. This means consumers can compare any 2 goods or services, and their preferences are internally consistent. Consumers can then rank-order the goods or services under consideration according to their personal “value function.” When making a decision under certainty, the value function reflects the decision maker’s preferences on a particular outcome.

Factors That Influence Young Adults’ Preferences for Virtual Reality Exergames in a Weight Control Setting: Qualitative Study

However, to our knowledge, systematic factors that influence young adults’ preferences for virtual reality exergames in a weight-control setting remain unclear. To develop and further refine the devices, guides, and policies for weight control–related virtual reality exergames, we need to better understand the factors that influence young adults’ preferences.

Understanding Patients’ Preferences for a Digital Intervention to Prevent Posttreatment Deterioration for Bulimia-Spectrum Eating Disorders: User-Centered Design Study

The first step is to learn core users’ needs and preferences (Investigate), generate initial product ideas (Ideate), create a minimally viable product as a prototype (Prototype), iteratively test the prototype (Evaluate), refine the design and develop the final product (Refine and Develop), and test the product in real-world (Validate) [22].

Preferences Regarding Information Strategies for Digital Mental Health Interventions Among Medical Students: Discrete Choice Experiment

Preferences Regarding Information Strategies for Digital Mental Health Interventions Among Medical Students: Discrete Choice Experiment

To our knowledge, only few DCEs examined information preferences on mental health services (eg, the study by Cunningham et al [27]), but none of them focused on DMHIs. Furthermore, while prior DCEs have focused on preferences regarding the delivery of DMHIs in the general population and among HCPs in Germany (refer to the studies by Phillips et al [28,29]), little is known about the specific information preferences regarding DMHIs in medical students.
