Thrive Care: Internet CBT for Depression

Population:

• As identified in Epic, Kaiser Permanente Southern California (KPSC) Fontana Family Medicine patients with a depression diagnosis recorded during the prior week (rolling basis).
• Target study enrollment: 150 participants per arm (300 total)

Recruitment:

• Kaiser Permanente (KP) will send eligible patients a postal letter inviting them to participate in study. Interested patients will be directed to the Enrollment/Assessment Website, a website to be developed by vendor Waypoint Health Innovations. The recruitment letter will contain (i) a description of the study, (ii) the web address for the Enrollment/Assessment Website, (iii) the patient's Study Identifier (ID).
• Additionally, KP will send eligible patients for whom KP has an email address an email inviting them to participate in the study.

Screening and Enrollment (Enrollment/Assessment Website):

• A patient interested in applying to the study will visit the Enrollment/Assessment Website and input his/her unique Study ID. The website will verify that the entered Study ID is on a pre-loaded list. If valid, the patient may continue to screening assessments.
• Patient will complete the 9-item Patient Health Questionnaire (PHQ-9) depression symptom assessment. Patients with eligible PHQ-9 scores may continue to Informed Consent page.
• The Informed Consent (IC) page will contain (i) the Informed Consent text including contact information for any questions patient may have; (ii) fields for first name, last name, date of birth, email address, and phone number; (iii) a check box labeled "I understand the above information and agree to participate…" (or similar); and (iv) a "submit" (or similar) button.
• To enroll in the study, the patient must complete all fields, check the box, and click submit button. The website will validate that every field has been completed and that the phone number and email fields have the correct format (e.g. [email protected] for the email field).
• If all fields are complete, the website will store the Study ID, first name, last name, date of birth, email address, and phone number that patient entered into the website. They will be stored in an encrypted database for use by researchers.
• Additionally, the website will store the complete Informed Consent page (including Informed Consent text, first name, last name, date of birth, email address, phone number, and checked box) in a single encrypted record, timestamp it, and place a digital certificate on it. The digital certificate will allow us to prove that no one tampered with any part of the IC document after the participant clicked submit.
• The website automatically randomizes participants to treatment or control arm. Participants continue in website to baseline assessments.
• After baseline assessments, control arm participants go to a page in the Enrollment/Assessment Website telling them to expect assessment again in 2 months, while treatment arm participants will be given instructions for enrolling in Thrive.
• Researchers would have access to the completed IC forms to print and/or mail to patients who request a copy.
• Weekly, KP research coordinator will review new participants' study ID, name, and date of birth (DOB) the participant entered to ensure they match KP records. Individuals who entered information that does not reasonably match KP records would be removed from the study.

Coaching:

• KP will send each treatment arm participant four emails encouraging them to use Thrive, with the exception that the second email will be replaced by a phone call from KP for patients who have not achieved a minimum level of activity in Thrive at that point.

Endpoint and Follow-up Assessments:

• KP will ask each study participant to visit Enrollment/Assessment Website 2 and 6 months after study enrollment to complete assessments.
