dc.description.abstractObjective The current study evaluates the usability perception of an e-therapeutic platform (supported by electronic processes and communication), aiming to promote the behavior change and to improve the adolescent health status through increased and interactive contact between the adolescent and the clinical staff. Methods This was a correlational study with a sample of 48 adolescents (12-18 years) who attended a Pediatric Obesity Clinic between January and August of 2012. Participants were invited to access, during 24 weeks, the e-therapeutic multidisciplinary platform (Next.Step) in addition to the standard treatment program. A usability questionnaire was administered and the platform performance and utilization indicators were analyzed. Results The users’ perception of satisfaction, efficiency, and effectiveness regarding the Next.Step platform was clearly positive. However, only 54.17% of the enrolled adolescents accessed the platform, with a mean task-completion rate of 14.55% (SD = 18.853). The higher the number of the platform consulted resources, the greater the tendency to enjoy the platform, to consider it exciting and quick, to consider that the time spent in it was useful, to consider the access to information easy, and to login easier. Post-intervention assessment revealed a significant reduction in anthropometric and behavioral variables, including body mass index z-score, waist circumference percentile, hip circumference, and weekly screen time. Conclusion These results highlight the importance of information and communication technologies in the health information access and the healthcare provision. Despite the limited adherence rate, platform users expressed a positive overall perception of its usability and presented a positive anthropometric and behavioral progress.pt_PT
