Developing Affective HeaLth to Improve Adherence to Health Behaviors in Diabetes (DAHLIA II)
- Conditions
- Diabetes Mellitus, Type 2
- Interventions
- Behavioral: Happify
- Registration Number
- NCT04068805
- Lead Sponsor
- Happify Inc.
- Brief Summary
Participants will be randomly assigned to either a positive affect skills intervention or a psychoeducation control group and assessed with questionnaires before, during, and after the 8-week program, as well as at 3 months, 6 months, and 12 months after the end of the program.
- Detailed Description
Participants will be randomly assigned to either the Diabetes positive affect skills intervention or a psychoeducation control group. Both programs last 8 weeks and take place on a simplified research version of the Happify platform. Participants assigned to the diabetes positive affect program will have full access to Happify, with a track that focuses on building skills for greater happiness, reducing stress, and coping better with diabetes displayed as the feature track. Participants assigned to the psychoeducation (control) condition will be asked to complete a series of polls on various wellbeing topics, and then provided with some social comparison data about how their responses compared with the responses of other users, as well as information about why the well being topic is important. Participants will be asked to complete questionnaires before, during, and after the 8-week program as well as 3 months, 6 months and 12 months follow-up questionnaires after the program is complete, at which point study participation will end.

Group Intervention Description Positive affect condition Happify Participants use Happify and have the option to use a diabetes-specific track that focuses on building skills for greater happiness, reducing stress, and coping better with diabetes. Users may access a wide variety of 4-week programs and use them in any way they desire for the entire study period. Psychoeducation condition Happify Participants complete a series of quizzes and polls on Happify designed to engage them in thinking about well-being topics, but without giving any specific instructions for how to promote well-being. Participants gain access to 8 weeks worth of content, but may repeat the content as often as they like in the follow-up period.
- Primary Outcome Measures
Name Time Method Change in self-reported HbA1C level Baseline, 3 weeks post-intervention (day 83), 3 weeks after 3-month post intervention (day 173), 3 weeks after 6 month post intervention (day 263), and 12 months post intervention (day 416) 1-item self-reported measure of Hemoglobin A1C (HbA1C) level, "What was your most recent HbA1c level?"
- Secondary Outcome Measures
Name Time Method Change in Diabetes Regimen Adherence From baseline up to 63 days, 7 days at 3 months post intervention (146-153), 7 days at 6 months post intervention (236-243), and 12 months post intervention (day 416-423) 1-item measure on keeping up with diabetes regimen in the past 24 hours, asking "Which of the following activities in your diabetes regimen did you complete over the past 24 hours?"
Change in Perceived Stress [Perceived Stress Scale (PSS)] Baseline, immediate post-intervention at 8 weeks, and at 3, 6, and 12 months post-intervention 10-item measure of perceived stress scoring how often the participant felt stressed by each statement in the following month from never (0) to very often (4).
Change in Depression symptoms [PHQ-9 questionnaire] Baseline, immediate post-intervention at 8 weeks, and at 3, 6, and 12 months post-intervention 9-item measure of depressive symptoms scoring how often the participant has been bothered by each statement over the past 2 weeks from not at all (0) to nearly every day (3).
Change in diabetes self-care activities [Summary of Diabetes Self-Care Activities (SDSCA)] Baseline, immediate post-intervention at 8 weeks, and at 3, 6, and 12 months post-intervention 11-item measure of self-reported adherence to diabetes self-care activities, ex. "On how many of the last seven days did you participate in at least 30 minutes of physical activity?" with possible answers of 0 to 7 days for each question.
Change in positive affect [Patient-Reported Outcomes Measurement Information Systems - Positive Affect Subscale(PROMIS)] Baseline, immediate post-intervention at 8 weeks, and at 3, 6, and 12 months post-intervention 15-item measure of positive affect scoring participants on how often then felt each statement was true over the past 7 days from not at all (1) to very much (5)
