Designing, Implementing and Assessing a Novel Text-Messaging Intervention for an Adolescent Mobile Health Clinic: A Collaborative Approach

Purpose: To determine if a text messaging intervention (TMI) delivering adolescent-relevant health information is feasible and effective at engaging underserved adolescents in a mobile health clinic setting. Methods: Mobile clinic adolescent patients, along with clinic staff, helped develop the text messaging content and format. Patients subsequently received text messages presenting health information in a question-and-answer format for 14 weeks. Participants could reply to receive messages with correct answers and further information. Focus groups and interviews were conducted post-intervention to evaluate messaging functionality and participant engagement. Results: All participants received and replied to texts for the duration of the study, and they reported high levels of engagement with the program. Participant input was instrumental in developing the structure and content of the text messages. Conclusions: TMIs that deliver health-related information are feasible in the mobile health care setting with high levels of engagement by underserved adolescents. Implications and contribution: Underserved adolescents will actively engage in TMI-based interventions aimed at disseminating health-related information, and these interventions have significant potential to increase knowledge and promote health-related behavior change. Moreover, adolescents can (and should) play an integral role in the development of these interventions.
