Selection of and Response to Physical Activity-Based Social Comparisons in a Digital Environment: Series of Daily Assessment Studies.

Background: Innovative approaches are needed to understand barriers to and facilitators of physical activity among insufficiently active adults. Although social comparison processes (ie, self-evaluations relative to others) are often used to motivate physical activity in digital environments, user preferences and responses to comparison information are poorly understood.

Objective: We used an iterative approach to better understand users' selection of comparison targets, how they interacted with their selected targets, and how they responded to these targets.

Using virtual reality to train inhibitory control and reduce binge eating: A proof-of-concept study.

Objective: One reason for limited efficacy of treatments for binge eating disorder (BED) and bulimia nervosa (BN) is a failure to directly target deficits in inhibitory control (i.e., the ability to withhold a pre-potent response).

Assessment of Evaluation Frameworks for Design of a Sexual Risk Prevention Game for Black Adolescent Girls.

Adolescent sexual risk behavior (SRB), a major public health problem affects urban Black adolescent girls increasing their health disparities and risks for sexually transmitted infections. Collaborating with these adolescents, we designed a game for smartphones that incorporates elements of trauma-informed care and social cognitive theory to reduce SRB. Game researchers promote use of a comprehensive, multipurpose framework for development and evaluation of games for health applications.

At-risk adolescents as experts in a new requirements elicitation procedure for the development of a smart phone psychoeducational trauma-informed care application.

Background/purpose: Adolescents from urban, socioeconomically disadvantaged communities of color encounter high rates of adverse childhood experiences. To address the resulting multidimensional problems, we developed an innovative approach, Experiential Participatory and Interactive Knowledge Elicitation (EPIKE), using remote experiential needs elicitation methods to generate design and content requirements for a mobile health (mHealth) psychoeducational intervention.

Methods: At a community-based organization in a northeastern city, the research team developed EPIKE by incorporating elicitation of input on the graphics and conducting remotely recorded experiential meetings and iterative reviews of the design to produce an mHealth smartphone story application (app) prototype for the participants to critique.
