eMoodie Experience Sampling 1.12.0

The “eMoodie” application represents a developmentally-informed tool tailored for experience sampling (ESM) and ecological momentary assessment (EMA) studies involving children and adolescents. Its primary purpose is to facilitate research on emotional and socialization patterns, digital technology engagement, and health-related factors such as physical activity and sleep among youth populations. The application supports the delivery of recurring surveys through notifications as well as traditional questionnaires, incorporating interactive feedback features like points and achievement systems to enhance participant engagement.

Building on established practices of utilizing visual aids and vignettes to clarify complex concepts for developmental samples, eMoodie allows researchers to integrate graphical elements into question and response formats. A distinct feature of the platform is its capacity to operationalize variables of interest via unobtrusive data collection from sensors and usage statistics on the device. For instance, accelerometer data can serve as an objective measure of physical activity, supplementing self-reported information.

Research protocols can be fully customized through an external web interface, enabling precise programming of study parameters. The application's user interface and graphic design merge a child-friendly aesthetic with a contemporary look to ensure appeal across a broad age range, including older adolescents and young adults. The versatility of eMoodie in capturing diverse types of real-time, objective data in conjunction with ecologically-valid ESM data promises to enhance the explanatory depth within developmental research methodologies.
