Armes et Interventions
Groupe de participants / Bras |
Intervention / Traitement |
|---|---|
|
Expérimental: REACH
Participants will receive REACH text messages (individual-focused text messaging tailored to user's individual barriers to adherence and targeted to address other self-care behaviors) for 12 months. All participants will also receive text messages advising how to access their study A1c test results, receive quarterly newsletters on healthy living with diabetes, and have access to a Helpline for study- and diabetes medication-related questions. |
The intervention consists of daily text messaging tailored to user's individual barriers to medication adherence, text messages assessing user's adherence with feedback on progress, plus text messaging targeting other self-care behaviors.
Participants complete study assessments, receive text messages advising how to access study A1c results, receive quarterly newsletters on healthy living with diabetes, and have access to a helpline for study- or diabetes medication-related questions.
|
|
Expérimental: REACH + FAMS
In addition to the REACH text messages tailored to user's individual barriers to adherence, participants will receive FAMS components (monthly phone coaching and text messages supporting a goal set in coaching, plus the option to invite a family member/support person to receive text messages) for six months. After six months, participants in this arm will receive REACH text messages only. All participants will also receive text messages advising how to access their study A1c test results, receive quarterly newsletters on healthy living with diabetes, and have access to a Helpline for study- and diabetes medication-related questions. |
Participants complete study assessments, receive text messages advising how to access study A1c results, receive quarterly newsletters on healthy living with diabetes, and have access to a helpline for study- or diabetes medication-related questions.
The intervention consists of REACH individually-focused text messaging, plus family-focused phone coaching session, goal-focused text messaging, and the option to invite a family member/support person to receive text messaging.

Comparateur actif: Helpline and A1c results
Participants assigned to the control group will complete measures at each time point and maintain care as usual (i.e., medical treatment and physician monitoring). All participants will receive text messages advising how to access their study A1c test results, receive quarterly newsletters on healthy living with diabetes, and have access to a Helpline for study- and diabetes medication-related questions. |

|
Change in Self-reported Medication Adherence
Délai: Baseline, 3 months, 6 months, 12 months, 15 months
|

|
Baseline, 3 months, 6 months, 12 months, 15 months
|
|
Change in Self-reported Medication Adherence
Délai: Baseline, 3 months, 6 months, 12 months, 15 months
|
as measured by the Adherence to Refills and Medications Scale for Diabetes (ARMS-D); reverse coded such that higher scores indicate better adherence on a scale from 11 to 44

Change in Adherence to Dietary Behavior
Délai: Baseline, 3 months, 6 months, 12 months, 15 months
|
as measured by the Personal Diabetes Questionnaire diet subscale "Use of information for decision making"; possible range 1-6, higher indicates more use of dietary information (better)

|
|
Change in Adherence to Dietary Behavior
Délai: Baseline, 3 months, 6 months, 12 months, 15 months
|

|
Baseline, 3 months, 6 months, 12 months, 15 months
|
|
Change in Physical Activity
Délai: Baseline, 3 months, 6 months, 12 months, 15 months
|
as measured by International Physical Activity Questionnaire-Short form [metabolic equivalent minutes (MET-minutes) per week] where more MET-minutes per week indicates more physical activity
