Developing Affective HeaLth to Improve Adherence to Health Behaviors in Diabetes (DAHLIA II)

July 15, 2022 updated by: Happify Inc.
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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Positive affect condition
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.
Behavioral: Happify
An online platform for conveying techniques from positive psychology, cognitive-behavioral therapy, and mindfulness-based stress reduction.
Sham Comparator: Psychoeducation condition
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.
Behavioral: Happify
An online platform for conveying techniques from positive psychology, cognitive-behavioral therapy, and mindfulness-based stress reduction.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in self-reported HbA1C level
Time Frame: 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?"
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)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
