Clinical Trial Summary
In this study, the investigators will test the effectiveness of a digital, low intensity
mental health intervention in depressed individuals. There will be two conditions: the Common
Elements Toolbox- Behavioral Activation (COMET-BA) intervention and a waiting list control
group. COMET-BA will include 4 weekly modules which will focus on elements of behavioral
activation, including positive activity scheduling, avoidance, values, and change plans. A
similar intervention, was previously tested in an online worker sample and participant
feedback was integrated into the current version of the intervention.
Description:
Participants who follow the study link in Prolific will immediately be taken to the Informed
Consent Statement (ICS), which will include a description of the study, risks and benefits,
payment, eligibility and confidentiality. After reading the ICS, participants will confirm
their consent by clicking "I consent to participate in this study." They will then be taken
to the welcome page for the study and confirm that they will provide their best answers (see
Attachments, "Screener"). Once participants have confirmed their consent, they will be asked
screener and demographic questions (i.e., age, sex assigned at birth, gender, race/ethnicity,
sexual orientation, relationship status, education level, annual income, employment status,
if they have ever taken psychiatric medication/engagement in mental health services, how many
people they can rely on for social support, physical health, how often they drink alcohol,
and how old they were when they first struggled with depression, anxiety, or stress). In
order to participate in the study, they must indicate "yes" that they are interested in
learning coping skills for their mental health at this time. This is meant to address
potential bias for online workers to participate in order to receive compensation without
interest in adhering to the intervention if randomized to the treatment arm. Additionally,
they will be administered the Patient Health Questionnaire 9-item (PHQ-9) and must reach the
threshold for elevated depression symptoms (total score > 9). Information about the screener
(e.g., types of questions) is provided to participants in the Informed Consent Form. Total
time to complete the screener is about 3 minutes.
Participants who are ineligible will be automatically sent to a page that notifies them they
do not qualify for the study. At this point their participation will be terminated.
Participants who are eligible for the study will then be prompted to complete the Week 1
Questionnaire (see Attachments, "Week 1") via the Prolific platform. Study team will send out
a Bulk Message to eligible participants to complete the weekly modules on a week-by-week
basis. The message to participants can be found in the Attachments, "Message". In this
questionnaire they will fill out a series of measures including: the Generalized Anxiety
Disorder 7-item (GAD-7), WHO-5 Well-being Index (WHO-5), 3 questions from the Insomnia
Severity Index (ISI), Emotion Regulation Questionnaire (ERQ), Ten-Item Personality Inventory
(TIPI), Adverse Childhood Experiences Scale (ACES), Work and Social Adjustment Scale (WSAS),
and the Behavioral Activation for Depression Scale Activation Subscale (BADS-AC). After
completing these questionnaires participants will be randomized to either the COMET-BA
intervention condition or the control condition (which will receive access to the
intervention after 8 weeks ). This randomization will be completed via the Qualtrics
randomizer function - which randomly and evenly assigns participants to the two conditions.
Participants who are assigned to the COMET-BA condition will then be taken to the first
intervention module (see Attachments, "Week 1"). They will then receive the first module,
Positive Activity Scheduling, where participants will learn about the theory underlying
behavioral activation and impact of scheduling positive activities. They will be asked to
brainstorm and plan a positive activity they can do in the next week. In total, the time
estimate for week 1 is about 10 minutes. Participants in the control condition will be
notified of the condition assignment and reminded about upcoming weekly questionnaires but
will not receive the module for week 1 until the study is over. The time to complete Week 1
for the control condition is about 5 minutes.
In the next week, participants will have access to the Week 2 modules through the Prolific
platform and sent a message through the Prolific platform (see attachments "Message"). All
participants will complete the weekly outcome measures, including the GAD-7, PHQ-9, WHO-5,
ERQ, WSAS, and BADS-AC. For those in the COMET-BA condition, they will receive the Avoidance
module (see Attachments, "Week 2"). First, participants will complete the weekly outcome
measures, including the GAD-7, PHQ-9, WHO-5, ERQ, WSAS, and BADS-AC. Participants in the
COMET-BA condition will then be asked about their adherence to last week's plan, receive
psychoeducation around the nature of avoidance in depression, and complete an exercise to
practice identifying avoidance strategies before they complete the another positive activity
scheduling exercise for the upcoming week. In total, the time estimate for week 2 is about 10
minutes. Participants in the control condition will be administered the questionnaires alone
and not the COMET-BA module. The time to complete the questionnaires for Week 2 is about 5
minutes.
In the third week, participants will have access to the Week 3 modules through the Prolific
platform and sent a message through the Prolific platform (see attachments "Message").
Participants will complete the weekly outcome measures, including the GAD-7, PHQ-9, WHO-5,
ERQ, WSAS, and BADS-AC, and then have access to the Week 3 modules through the Prolific
platform. For those in the COMET-BA condition, they will receive the Values module (see
Attachments, "Week 3"). First, participants will complete the weekly outcome measures,
including the GAD-7, PHQ-9, WHO-5, ERQ, WSAS, and BADS-AC. Participants in this module will
again be asked about their adherence to last week's plan, receive psychoeducation around the
nature of and benefit to acting on one's values, and complete an exercise to practice
identifying their values and a plan to act on them in the upcoming week. In total, the time
estimate for Week 3 is about 10 minutes. Participants in the control condition will be
administered the questionnaires alone and not the COMET-BA module. The time to complete the
questionnaires for Week 3 is about 5 minutes.
In the fourth week, participants will have access to the Week 4 modules through the Prolific
platform and sent a message through the Prolific platform (see attachments "Message").
Participants will complete the weekly outcome measures, including the GAD-7, PHQ-9, WHO-5,
ERQ, WSAS, and BADS-AC, and then have access to have access to the Week 4 modules through the
Prolific platform. For those in the COMET-BA condition, they will receive the Change Plan
module (see Attachments, "Week 4"). First, participants will complete the weekly outcome
measures, including the GAD-7, PHQ-9, WHO-5, ERQ, WSAS, and BADS-AC. Participants in this
module will again be asked about their adherence to last week's plan, then receive
psychoeducation around the nature of change plans and complete a change plan exercise for the
future. In total, the time estimate for Week 4 is about 10 minutes. Participants in the
control condition will be administered the questionnaires alone and not the COMET-BA module.
The time to complete the questionnaires for Week 4 is about 5 minutes.
Participants who are assigned to the control condition will receive weekly links through
Prolific similar to the COMET-BA condition, but rather than receiving a module they will be
directed to a series of questionnaires identical to the weekly questionnaires outlined in the
COMET-BA condition (GAD-7, PHQ-9, WHO-5, ERQ, WSAS, and BADS-AC). This is all the control
condition will be completing. Provided the intervention condition will entail completing an
online, survey-style intervention, the control condition will similarly be completing weekly
surveys as a "waitlist" condition until the end of the study, when the intervention materials
will be made available freely for all participants. All surveys and intervention materials
will end with a mental wellbeing resource list (see Attachments, "Resource List") for both
the Control and COMET-BA groups.
After completing the COMET-BA intervention, all participants from both conditions will
receive a 1-week follow-up after the completion of the Week 4 module (see Attachments,
"Follow-Up 1"). This will include the PHQ-9, GAD-7, WHO-5, ERQ, ISI, WSAS, and the BADS-AC.
The same questionnaire will be sent out 3 weeks later to establish a 4-week follow-up (see
Attachments, "Follow-Up 2"). Thus, the total time for the study from start to end is about 8
weeks. In the informed consent statement, participants will be informed that there are
follow-up assessments that they can receive additional compensation for. The study team will
also put a message at the end of each module reminding them to watch for the follow ups. They
will not be notified of these follow-up assessments, but will be able to see the follow-up
assessments posted on Prolific. Participants who do not complete the follow up assessments
within 1 day will be sent a reminder within Prolific's system (see Attachments, "COMET-BA
Prolific Follow Up Reminder"). During these follow-ups all participants (e.g., those in both
the intervention and control conditions) will complete the following questionnaires: GAD-7,
PHQ-9, WHO-5, ISI, ERQ, WSAS, and BADS-AC.
After completing the follow-up measure at 8 weeks, enrollment in the study will end. At this
point, participants in the control condition will receive the intervention modules via a link
through the Prolific platform (see "Final Message Prolific"). Whether they complete the
intervention or not is entirely up to them and it will not be tracked by the research team.
Their use of the COMET intervention is entirely optional and will not be recorded by the
research team. They will not fill out any follow up measures after completing or not
completing the COMET intervention. The materials are made available so they may also access
the materials available to those in the intervention condition as they may desire.
