<qa>  What is the name of the program that includes a practical, time-efficient patient engagement protocolTo date there has been no systematic study of the degree to which fully integrating enhanced patient engagement as part of SMS will increase the initiation and maintenance of behavior change over time, and for which kinds of patients enhanced patient engagement is essential. To address this gap, the investigators will compare a state-of-the-art, evidence-based SMS behavior change tool program, called Connection to Health CTH, with an enhanced CTH program that includes a practical, time-efficient patient engagement protocol, to create a program with an integrated and comprehensive approach to SMS, called Enhanced Engagement CTH EE-CTH. The current study will directly test the added benefit of EE-CTH to CTH with regard to self-management behaviors and glycemic control in resource-limited community health centers, where vast numbers of patients with T2DM from ethnically diverse and medically vulnerable populations receive their care. The investigators will use an effectiveness-implementation hybrid design, employing the Reach Effectiveness Adoption Implementation Maintenance RE-AIM framework to test these two SMS programs for T2DM. This will provide critical information that will support dissemination and implementation of effective SMS programs in resource-limited primary care settings, serving diverse and medically vulnerable populations with much to gain from improved SMS.
