Arm && Interventions

Group	Intervention	Description
Habit Formation Interventions	Habit formation	Single subject design used for individual control (A-B design). During baseline phase (A), participants completed self-care activities ratings once per week for 4 weeks. During intervention phase (B), participants engaged in weekly sessions to address goals related to diabetes self-management and guided in habit formation. Participants engaged in intervention for 10 weeks, in accordance with habit formation recommendations by Lally et al. (2010). Each weekly session were held virtually (telephone or Zoom) and lasted 30-60 minutes, beginning with administration of the SDSCA and SRBAI. Participants were instructed in ongoing context-specific implementation intention to promote occupational participation in DSM through habit formation. This instruction included continued education and context modification recommendations. At two week intervals, additional areas of DSM were added until each were covered: blood glucose monitoring, nutrition, medication management, and physical activity.

Primary Outcome Measures

Name	Time	Method
Change in Diabetes Self-Care	13 weeks	The Summary of Diabetes Self-Care Activities (SDSCA) is a self-report questionnaire of DSM (diet, exercise, blood-glucose monitoring, foot care, and smoking) for which individuals report frequency of activities during the past 7 days (Toobert et al., 2000). A global self-care behavior score (average of items 1-10) was reported in days per week the participant executed self-care activities. In addition, combined subscales were used for general diet, specific diet, exercise, and blood glucose testing using a global average of items 1-8, reported in days per week. As part of baseline phase data collection (Phase A), the Summary of Diabetes Self-Care Activities (SDSCA) was administered once weekly for 4 weeks. Following the initial evaluation, interventions (phase B) were provided to participants once per week for 10 weeks and began with administration of the SDSCA.
Change in Behavior Automaticity	10 weeks	The Self-Report Behavior Automaticity Index SRBAI is a measure of habit strength and automaticity. Individuals respond how they perform a target behavior using a 7-point scale, with 7 meaning a better outcome. The initial evaluation session closed the baseline phase (Phase A) and initiated the intervention phase (Phase B) of the study. In this initial session, individuals were guided in setting a context-specific implementation intention for habit formation of a simple occupational habit related to nutrition. These nutrition intentions were utilized to create target behaviors for the Self-Report Behavioral Automaticity Index (SRBAI), which was administered at the end of the first session. Following the initial evaluation, interventions were provided to participants once per week for 10 weeks and began with administration of the SRBAI.
