About this study
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.
Read the detailed description
This is a fast track Small Business Innovation Research (SBIR) proposal that will (1) test the effectiveness of daily, message-based psychotherapy (MBP) for depression, compared to traditionally delivered, video-chat psychotherapy (VCP) and (2) develop an evidence-based treatment sequence for those who do not respond to either daily MBP or VCP.
Phase 1 consists of a pilot study to determine the best incentive model to retain a sample of people 18 years old and older with depression into a SMART trial. Information from this pilot will inform the retention strategy for Phase 2.
Phase 2 is a 12-week, randomized clinical trial using a SMART design to test the following aims: 1. Determine the relative effectiveness of daily MBP compared to weekly VCP in treating symptoms of depression and improving social functioning; 2. For those who fail to respond to 6 weeks of weekly VCP only, determine whether the addition of daily messaging, or a switch to monthly video-chat plus daily messaging improves depression and functional outcomes; and 3. For those who fail to respond to 6 weeks of daily MBP, whether the addition of monthly video-chat or weekly video-chat improves outcomes. Participants will provide data on mood, activity, and functioning, and we will collect data on use of treatment (texts and sessions), and working alliance.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Video-Chat Psychotherapy (VCP)Behavioural
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.
Message-Based Psychotherapy (MBP)Behavioural
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 with Monthly Video-Chat PsychotherapyBehavioural
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 with Weekly Video-Chat PsychotherapyBehavioural
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. Therapists will provide care based on CBT, PST or IPT. In Phase 1, this is referred to as the "Augmentation Arm". In Phase 2, this is referred to as the "Ultimate Plan."
High Monetary Incentive (HMI)Behavioural
Participants in the traditional, high monetary incentive arm will receive a total of $125 for completing 12 weeks of assessments.
Low Monetary and Alternative Incentive (LMAI)Behavioural
Participants in the Low Monetary and Alternative Incentive (LMAI) arm received a total of $75 for completing 12 weeks of assessments, messages of encouragement for completing daily assessments, and weekly texts showing participants their clinical improvement and assessment completion rate.

What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: 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.
Measured: Change from Baseline PHQ-9 at 6 weeks and 12 weeks after treatment starts
Secondary outcomes (1)
Change in Generalized Anxiety Disorder (GAD-7)
To assess for co-occurring anxiety, we will use the Generalized Anxiety Disorder-7 (GAD-7), a 7- item screener for generalized anxiety disorder (GAD). Participants rate on a scale of 0-3 how much they have experienced symptoms of GAD in the last two weeks. Total scores range from 0 to 21, with higher scores indicating greater severity of anxiety. The scale is a valid screener for GAD.
Measured: Change from Baseline GAD-7 at 6 weeks and 12 weeks after treatment starts

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

Interventions
| Intervention | Type | Arms |
|---|---|---|
| Video-Chat Psychotherapy (VCP)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. | Behavioural | 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)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. | Behavioural | Phase 1: High Monetary Incentive (HMI) + MBP (Level 1 and Level 2), Phase 1: Low Monetary and Alternative Incentive (LMAI) + MBP (Level 1 and Level 2), Phase 2: MBP (Level 1) to Premium Plan (MBP with monthly VCP; Level 2), Phase 2: MBP (Level 1) to Ultimate Plan (MBP with weekly VCP; Level 2), Phase 2: Message-Based Psychotherapy (MBP; Level 1 and Level 2) |
| Message-Based Psychotherapy with Monthly Video-Chat PsychotherapyMessage-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". | Behavioural | Phase 1: HMI + MBP (Level 1) to Minimal Augmentation (MBP with monthly VCP; Level 2), Phase 1: HMI + VCP (Level 1) to Switch Arm (MBP with monthly VCP; Level 2), Phase 1: LMAI + MBP (Level 1) to Minimal Augmentation (MBP with monthly VCP; Level 2), Phase 1: LMAI + VCP (Level 1) to Switch Arm (MBP with monthly VCP; Level 2), Phase 2: MBP (Level 1) to Premium Plan (MBP with monthly VCP; Level 2), Phase 2: VCP (Level 1) to Premium Plan (MBP with monthly VCP; Level 2) |

Therapists will provide care based on CBT, PST or IPT. In Phase 1, this is referred to as the "Augmentation Arm". In Phase 2, this is referred to as the "Ultimate Plan." | Behavioural | Phase 1: HMI + MBP (Level 1) to Augmentation Arm (MBP with weekly VCP; Level 2), Phase 1: HMI + VCP (Level 1) to Augmentation Arm (MBP with weekly VCP; Level 2), Phase 1: LMAI + MBP (Level 1) to Augmentation Arm (MBP with weekly VCP; Level 2), Phase 1: LMAI + VCP (Level 1) to Augmentation Arm (MBP with weekly VCP; Level 2), Phase 2: MBP (Level 1) to Ultimate Plan (MBP with weekly VCP; Level 2), Phase 2: VCP (Level 1) to Ultimate Plan (MBP with weekly VCP; Level 2) |
| High Monetary Incentive (HMI)Participants in the traditional, high monetary incentive arm will receive a total of $125 for completing 12 weeks of assessments. | Behavioural | Phase 1: HMI + MBP (Level 1) to Augmentation Arm (MBP with weekly VCP; Level 2), Phase 1: HMI + MBP (Level 1) to Minimal Augmentation (MBP with monthly VCP; Level 2), Phase 1: HMI + VCP (Level 1) to Augmentation Arm (MBP with weekly VCP; Level 2), Phase 1: HMI + VCP (Level 1) to Switch Arm (MBP with monthly VCP; Level 2), Phase 1: High Monetary Incentive (HMI) + MBP (Level 1 and Level 2), Phase 1: High Monetary Incentive (HMI) + VCP (Level 1 and Level 2) |

Primary outcome
Change in Neuro-QOL - Ability to Participate in Social Roles and Activities
Time frame: Change from Baseline Neuro-QOL at 6 weeks and 12 weeks after treatment starts
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 in Patient Health Questionnaire (PHQ-9)
Time frame: Change from Baseline PHQ-9 at 6 weeks and 12 weeks after treatment starts
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.
1 secondary outcome
Change in Generalized Anxiety Disorder (GAD-7)
Time frame: Change from Baseline GAD-7 at 6 weeks and 12 weeks after treatment starts
