On the body of the consumer: performance‐seeking with wearables and health and fitness apps

Contributing to critical digital health research and the sociology of health consumption, this study investigates the phenomenon of self‐tracking and interpretation of consumer data via wearable technology and mobile fitness software applications (apps). It critically analyses qualitative data collected from members of running communities in the UK who are heavy users of apps and wearables. The study seeks to understand the meaning and practise of long‐term use of apps and wearables targeted at consumers interested in tracking fitness, and the collection of personal health information over time. The paper offers an interpretative perspective on runners as performance‐seeking fitness consumers engaged in long‐term self‐management of health. These consumers are driven by a profound motivation to visualise and embody a long‐term state of fitness. Participants were also hyper‐aware of advertising and promotional methods used to engage consumers. The findings raise concerns about the validity of personal fitness data, and how its collection promises improved personal health while visually promoting sought‐after fit bodies. Further research is required to understand the transformative impact of fitness‐tracking and how individuals negotiate personal classifications of health.

Personal characteristics and school contextual variables associated with student self-determination in Spanish context

Background: Most theoretical models of self-determination suggest that both environmental and personal factors influence the development of self-determination. The design and implementation of interventions must be conducted with foreknowledge of such mediating and moderating factors if the intervention is to be successful.

Methods: The purpose of this study was to examine the degree to which several personal factors and school characteristics affect and explain students’ self-determination. A total of 232 students with intellectual disability from Spain participated. Their self-determination level was assessed by the ARC-INICO Scale.

Results: Students with moderate levels of intellectual disability obtained significantly lower scores on self-determination than their peers with mild intellectual disability. There were significant differences in relation to the level of support needs and their experience with transition programs. The level of support needs was a significant predictor.

Conclusion: These findings contribute to current research in this field and practical implications were discussed.
