Researchers used text messaging as an educational and motivational tool to increase physical activity among patients with type 2 diabetes (T2DM). Study participants in the intervention arm received tailored text messages twice daily for six months and then were interviewed by the investigators regarding their level of satisfaction with the TTM model. Participants reported an overall satisfaction with the TTM modality, specifically an increased sense of connection with their healthcare centers and a greater sense of self-accountability. Participants also reported dissatisfaction with the automation of the texts (e.g., repetitiveness, predictability, lack of customization/ interactivity). The authors discuss how the text messaging modality may be improved for use in clinical trials and in clinical practice for optimal patient outcomes.
