NCT04513080

Brief Summary

This partnership between Talkspace and the University of Washington (UW) ALACRITY Center will determine how effective unlimited text-based psychotherapy for depression is when compared to once-a-week psychotherapy. This study will also determine what the best treatment options are for people who are not responding well to either unlimited texting or weekly psychotherapy. The results of this study will be a new product version of message-based care that can tailor psychotherapy intensity based on the needs of future consumers with depression.

Outcome Measures

Primary Outcomes (2)

  • Change in Neuro-QOL - Ability to Participate in Social Roles and Activities

    Neuro-Quality of Life v1.0 (Neuro-QOL). The Neuro-QOL Ability to Participate in Social Roles and Activities short form item bank is an 8-item patient-rated measure of social functioning. Items focus on difficulty participating in social, family, and work activities, and are rated on a 1 to 5 scale for a total score between 8 and 40. Neuro-QOL scores were transformed into t-scores per the scoring manual; after transformation, total scores range from 24.1 to 60.2. Transformed scores are reported. Higher scores indicate less difficulty participating in social roles and activities. The Neuro-QOL was not distributed in Phase 1.

    Change from Baseline Neuro-QOL at 6 weeks and 12 weeks after treatment starts

  • Change in Patient Health Questionnaire (PHQ-9)

    The Patient Health Questionnaire-9 (PHQ-9) consists of 9 depression items and one disability item. Each time is associated with a Diagnostic and Statistical Manual (DMS) symptom of depression, which the participant rates whether or not they have experienced the symptom over the last two weeks, with severity rating of 0-3. It is one of the few measures that is brief (it takes less than one minute to give) and has been found to have excellent sensitivity to change over time. Total scores range from 0-27, with higher scores indicating greater severity of depression.

    Change from Baseline PHQ-9 at 6 weeks and 12 weeks after treatment starts

Secondary Outcomes (1)

  • Change in Generalized Anxiety Disorder (GAD-7)

    Change from Baseline GAD-7 at 6 weeks and 12 weeks after treatment starts

Interventions

Video-Chat Psychotherapy (VCP) consists of weekly psychotherapy appointments that last between 30-45 minutes. These sessions are conducted using Agora, a secure, HIPAA-compliant video conferencing service that is seamlessly integrated into the Talkspace platform application. Therapists will provide evidence-based treatments for depression and anxiety.

Phase 1: High Monetary Incentive (HMI) + VCP (Level 1 and Level 2)Phase 1: Low Monetary and Alternative Incentive (LMAI) + VCP (Level 1 and Level 2)Phase 2: VCP (Level 1) to Premium Plan (MBP with monthly VCP; Level 2)Phase 2: VCP (Level 1) to Ultimate Plan (MBP with weekly VCP; Level 2)Phase 2: Video-Chat Psychotherapy (VCP; Level 1 and Level 2)

Message-Based Psychotherapy (MBP) allows patients to chat with an assigned licensed therapist as frequently as they wish. After consumers complete an intake and select a therapist, the consumer can begin chatting with their therapist right away, and as often as they wish. Therapists respond to text within 15 minutes to an hour during office hours, and within 14 hours outside of office hours. Thus, MBP is not fully synchronous. This enables therapists to deliver care to a larger number of patients than is possible under synchronous methods by disentangling the therapist's time from the patient's time to respond. It also has the potential to improve quality as it gives the therapist time to think through the most effective response and intervention. MBP will be based on CBT, PST or IPT intervention strategies.

Message-Based Psychotherapy (MBP) with monthly Video-Chat Psychotherapy (VCP) allows patients unlimited texting with their therapist and once a month, 30-45 minute video chat with the same therapist. Therapist and participants schedule their video chat appointment to occur at once a month interval during therapist office hours. The content of these sessions, as well as the MBP portion of care, will be based on CBT, PST or IPT. In Phase 1, this is referred to as "Switch Arm" (for participants assigned to VCP at baseline) or "Minimal Augmentation" (for participants assigned to MBP at baseline). In Phase 2, this is referred to as the "Premium Plan".

Message-Based Psychotherapy (MBP) with weekly Video-Chat Psychotherapy (VCP) allows patients access to both unlimited MBP, but will be able to schedule weekly, 30-45 minute video chat with the same therapist.

Model Details: Phase 1 will test the effectiveness of two forms of participant retention methods into a SMART (sequential, multiple assignment, randomized). In Phase 1, participants (n=200) will be randomized to an incentive level and then randomized to treatment arms. Phase 2 (n=1000) will be the subsequent SMART design comparing message-based psychotherapy (MBP) to video-chat psychotherapy (VCP) in level 1 and for those who do not respond to care after 6 weeks, those participants will be randomized to either MBP+monthly VCP or MBP+weekly VCP. Arms/Interventions have been adjusted to align with the results for the Phase 2 SMART.
