This SBIR NIDA-funded project (funding pending) is a collaboration with Woebot, a technology start up
that is using artificial intelligence (AI) in a bot to deliver tailored messaging to improve mental health.
Woebot customers within the U.S. will be engaged in Phase 1
Participants will be recruited through a wide variety of strategies including but not limited to paid online
advertising (e.g., sidebar Gmail and Yahoo advertisements); free online and email advertising (e.g., Dr
Prochaska's laboratory webpage, email listservs of digital health companies and the Stanford University
student, faculty, and staff community); and national outpatient clinics with substance abuse programming
including Stanford's Department of Psychiatry and Behavioral Sciences' Dual Diagnosis Clinic.
Dr. Prochaska's team has extensive experience in recruiting research participants who use substances,
including for online studies and has published on best practices.
f)
Access to resources if needed as a consequence of the research.
State whether you have medical or psychological resources available that participants might require as
a consequence of the research when applicable. Please describe these resources.
Foreseeable risks to subjects include the possibility that some assessment questions and/or treatment
procedures may be upsetting to subjects. Experience at Stanford with similar populations has indicated that
the risk of emotional upset during the assessments is low and if it occurred, the upset would likely not be
serious in nature and temporary. Such risks will be minimized by the thoughtful selection of questionnaires.
Potential participants will also be informed that they may drop out of the study at any time and if requested,
appropriate treatment referrals would then be given.

1. Purpose
a)
In layperson's language state the purpose of the study in 3-5 sentences.
This study aims to develop a digitally-delivered substance use
disorder program through the
platform to inform a
study that will test the comparative efficacy of the mobile-app based
substance use disorder program to reduce substance use relative to a
standard control condition, and explore between group differences on
quality of life indices as well as retention and engagement.
b)
State what the Investigator(s) hope to learn from the study. Include an assessment of the importance of
this new knowledge.
This study will be the first empirical evaluation of a SUDs focused
digital therapeutic delivered via an Artificial Intelligence (AI)-
powered Conversational Agents (CAs). Results will impact the
intersection of collaboration between technology (engineering, AI,
Natural Language Processing) and the mental health care field
(providers, clinics). It may broaden the spectrum of products
worthy of distribution by payers and reimbursement by insurers. If
Woebot-SUDs is efficacious, it could ultimately reduce the population
level burden of disease by becoming an immediately available tool for
millions of Americans who have no other access to care. Thus, results
may impact the clinical field's understanding of implementation
science, highlighting the mass adoption potential of an efficacious
digital therapeutic CA.
c)
Explain why human subjects must be used for this project. (i.e. purpose of study is to test efficacy of
investigational device in individuals with specific condition; purpose of study is to examine specific
behavioral traits in humans in classroom or other environment)
The purpose of this study is to test the efficacy of a mobile-
application delivered substance use disorder intervention in adult
humans.
2. Study Procedures
a)
Please SUMMARIZE the research procedures, screening through closeout, which the human subject
will undergo. Refer to sections in the protocol attached in section 16, BUT do not copy the clinical
protocol. Be clear on what is to be done for research and what is part of standard of care.
This study will be one of two phases. Updated consent forms and HIPAA
authorization will be uploaded before the start of recruitment. Ads,
questionnaires, etc. will be uploaded for review before recruitment
begins.
Woebot will facilitate recruitment of study participants in the
research since the sample will be drawn from current Woebot users.
This facilitation will take the form of communicating the research
opportunity through social media channels and potentially to current
Woebot users. Working with Dr. Prochaska's research team at Stanford,
the Woebot team will take part in mapping out message development for
the intervention and Woebot's IT team will lead the app programming
(including build and quality control/de-bugging). Woebot will collect
user data via the Woebot app (automatic process), which will be
provided to the Stanford team. The Woebot team will participate in

disseminating the study findings via publications and presentations.
Participants from Woebot's recruitment channels will go through and
eligibility screener and if eligible, will be asked to use the W-SUDS
for 8 weeks and answer a couple of questionnaires administered at the
beginning and end of the 8 week period. The data from the
questionnaires and app usage during the 8 week period will be
analyzed to inform the next study. Woebot will rely on Stanford
University IRB for review of this Phase I study.
The Stanford team will lead the study evaluations including the study
measures, data collection (baseline and follow-ups), data analyses,
and writing up of study findings for dissemination.
In order to better understand what specific W-SUDs content the
participants like, Lesson Completion Rates and Content Rating Metrics
will be analyzed. Descriptive statistics will be used for the
following scales: Usage Rating Profile Intervention (UPRI)-
Acceptability, Usage Rating Profile Intervention (UPRI)--Feasibility,
and Client Satisfaction Questionnaire (CSQ-8). Such descriptive
statistics will provide a summary index of how likable the content
and program was overall. Due to the small sample size of this pilot
study, effect sizes, rather than tests involving statistical
significance, will be used to assess the intervention's impact from
baseline to EOT.
Utilizing pilot study results as described above, the research team
will refine W-SUDs. The intent is to utilize and leverage what was
learned in in this pilot to produce an enhanced version of W-SUDs in
the next study.
b)
Explain how the above research procedures are the least risky that can be performed consistent with
sound research design.
Given that the research aims to enroll a low-treatment seeking
population, we do not envisage that participation in the study will
be associated with elevated risk.
However, some risk is always present in studies that involve human
participants.
Such risk may include the following:
Risk from breach of protected health information.
Possibly the greatest risk is from a leak of health information. All
study data are gathered on a HIPAA compliant web platform that
resides behind Stanford security firewalls and has been tried and
tested by the University for several years, thus actual risk from
data breach for study data is low. In addition, the Woebot
application encrypts all message data exchanged between service users
and Woebot, and collects minimal protected health information.
Emails are hashed and not kept along side message data so that they
are not easily associated with each other. In addition, the product
recently became compliant with General Data Protection Regulations
(GDPR) in the European Union which entails a user-ownership model of
data protections.
Risk from answering questions that may be emotionally upsetting.
Experience at Stanford with similar populations has indicated that
the risk of emotional upset during the assessments is low and if it

occurred, the upset would likely not be serious in nature and
temporary. Such risks will be minimized by the thoughtful selection
of questionnaires. Potential participants will also be informed that
they may drop out of the study at any time and if requested,
appropriate treatment referrals would then be given.
Risk of treatment avoidance due to engagement with either of the
randomized interventions. In both interventions it is explicitly
stated that the service should not be used in place of traditional
treatment. In the case of the W-SUDs intervention, Woebot is designed
to hold individuals accountable for pursuing additional options in
conditions of unchanged symptoms for a prolonged amount of time (4
weeks). In addition, Woebot will invite the user to consider what
seeking additional services would look like.
c)
State if deception will be used. If so, provide the rationale and describe debriefing procedures. Since
you will not be fully informing the participant in your consent process and form, complete an
alteration of consent (in section 13). Submit a debriefing script (in section 16).
No deception will be used.
d)
State if audio or video recording will occur. Describe what will become of the recording after use, e.g.,
shown at scientific meetings, erased. Describe the final disposition of the recordings.
No audio or video recordings will occur.
e)
Describe alternative procedures or courses of treatment, if any, that might be advantageous to the
participant. Describe potential risks and benefits associated with these. Any standard treatment that is
being withheld must be disclosed in the consent process and form. (i.e. standard-of-care drug, different
interventional procedure, no procedure or treatment, palliative care, other research studies).
Alternative Treatments for SUDSs include in-person individual and
group forms of psychotherapy as well as Alcoholics Anonymous and
Narcotics Anonymous.
All alternative options will be provided if she/he/they wishes to
engage in an alternative treatment rather than the proposed study.
However, given that previous Woebot study results are promising, the
proposed line of treatments would appear to be appropriate and
acceptable interventions for SUDs.
No standard treatment is being withheld.
f)
Will it be possible to continue the more (most) appropriate therapy for the participant(s) after the
conclusion of the study?
Yes
g)
Study Endpoint. What are the guidelines or end points by which you can evaluate the different
treatments (i.e. study drug, device, procedure) during the study? If one proves to be clearly more
effective than another (or others) during the course of a study, will the study be terminated before the
projected total participant population has been enrolled? When will the study end if no important
differences are detected?
The endpoint will be the 2-month end-of-treatment survey. This will
end the pilot study and study staff will do analysis.

a)
Describe past experimental and/or clinical findings leading to the formulation of the study.
An RCT demonstrated that Woebot had statistically
and clinically significant reductions in depression compared to a
control group, along with best in class app-engagement rates (mean=12
interactions in 14 days). Woebot does not currently offer a SUDs
program, although 63% of current users expressed interest in said
content. Woebot's current, substantial reach as a consumer app,
preliminary data indicating its high user engagement plus efficacy
to treat a psychological condition, posies it as an ideal platform
for a SUDs-focused, tailored, and immediately scalable digital
therapeutic.

a)
State the following: (i) the number of participants expected to be enrolled at Stanford-affiliated site(s);
(ii)the total number of participants expected to enroll at all sites; (iii) the type of participants (i.e.
students, patients with certain cancer, patients with certain cardiac condition) and the reasons for
using such participants.
N =50 will be invited to participate in this pilot study and entered into the study on a rolling basis.
Recruitment will be a joint effort by Stanford University and Woebot Labs. Neither election or declining to
participate in the study will impact Woebot users ability to continue using the product as they wish.
Inclusion criteria include: all genders aged 18-65 years, access to Woebot on smartphone, be available and
committed to engage with app and complete assessments, be willing to provide email address (to distribute
incentives), and be literate in English (as W-SUDs conversational and video materials will be in English).
Exclusion criteria include: pregnancy (as W-SUDs will not be specifically developed to address the unique
needs of this population), history of severe drug/alcohol use, opioid misuse without medication-assisted
treatment, and suicide attempt or opioid overdose within the past year. Randomization will not be employed
in this study given that it is a preliminary uncontrolled pilot study geared toward ascertaining the feasibility,
acceptability, and preliminary efficacy of the newly developed W-SUDs content.
Participants and Recruitment: N=50 will be invited to participate in this pilot study. Woebot exchanges one
to two millions messages per week with users, 66% of whom expressed interest in substance abuse content.
Therefore, we anticipate enrollment of the n=50 sample in less than 2 weeks. Recruitment channels may
include Woebot Labs' social media avenues (e.g., Facebook, Twitter, LinkedIn, Woebot.io), Craigslist,
Reddit, physical flyers, posting to Stanford Staffers listserv, and through Woebot itself. Participants will be
entered into the study on a rolling basis. Neither election or declining to participate in the study will impact
Woebot users ability to continue using the product as they wish. Inclusion criteria include: all genders aged
18-65 years, access to Woebot on smartphone, be available and committed to engage with app and complete

ascertaining the feasibility, acceptability, and preliminary efficacy of the newly developed W-SUDs content.
Intervention Delivery: W-SUDs will be administered over the course of 8-weeks during the pilot.
Survey Administration Plan: Qualtrics or REDCap, HIPAA compliant online data center survey
administration tools (commonly used by Stanford University), will be utilized to administer the assessment
batteries including BL the EOT questionnaires. During the consent form section, participants will be asked
for their email in order to receive study communications including 1) Their signed consent form, 2)
Instructions for downloading the Woebot app and using the referral code for the Woebot-SUDs program,
and 3) A survey link for EOT assessment. After the baseline is completed, participants will be emailed their
signed consent form and instructions. After the 8-week phase, participants will receive their EOT link via
email.
Data Analysis: In order to analyze feasibility and acceptability data, descriptive statistics will be used for the
following scales: Usage Rating Profile Intervention (UPRI)-Acceptability, Usage Rating Profile
Intervention (UPRI)--Feasibility, and Client Satisfaction Questionnaire (CSQ-8). Such descriptive statistics
will provide a summary index of how likable the content and program was overall.
In order to better understand what specific W-SUDs content the participants like, Lesson Completion Rates,
and Content Rating Metrics will be analyzed.
Lesson Completion Rates will indicate which of the specific W-SUDs lessons were completed. Content
Rating Metrics are how participants rate each lesson; they are self-reported by the participant, via Woebot,
and are provided on a binary scale: either a thumbs up or thumbs down emoticon. If a lesson receives a
thumbs down, Woebot offers the user a chance to give additional free-text feedback. Thus, both the binary
answers (thumbs up or thumbs down) plus the free-text feedback will be used to pinpoint which lessons are
performing well and which need editing. Effect sizes will surmise mean changes from baseline to
post-treatment on drug use psychopathology. Due to the small sample size of this pilot study, effect sizes,
rather than tests involving statistical significance, will be used to assess the intervention's impact from
baseline to EOT.
Additionally, pain and craving questions will be asked in the Woebot app to monitor change over time.
Subtle changes to wording in these questions may be made for organic conversation.
Refining W-SUDs: Utilizing pilot study results as described above, the research team will refine W-SUDs.
The intent is to utilize and leverage what was learned in in this pilot to produce an enhanced version of
W-SUDs in the next study.
b)
State the age range, gender, and ethnic background of the participant population being recruited.
Inclusion Criteria:
Eligible participants for this trial must:

0 healthy volunteers. 50 volunteers will have endorsed a substance use concern for problematic use and
screened out if pregnant during recruitment. Other than these health implications, participants will otherwise
be healthy volunteers and will not be exposed to health risks through their participation.
g)
How will you identify and recruit potential participants about the research study? (E.g., by: chart
review; notified by treating physician; response to ad). All final or revised recruitment materials,
flyers, etc. must be submitted to the IRB for review and approval before use. You may not contact
potential participants prior to IRB approval. See Advertisements: Appropriate Language for
Recruitment Material.
Recruitment: For this pilot study, Woebot Labs' will post study advertisements and recruit via their already
active internet channels including Twitter (over 2,000 followers), LinkedIn (over 400 followers), and
Facebook (over 16,500 followers). To supplement recruiment, Woebot Labs' may post on Craigslist, and on
Reddit through relevant subreddits with written permission from the subreddits' moderators. In addition,
Woebot (the CA itself) may, within the application, invite its entire current user base to participate in the
study. Woebot may also post physical flyers and the Stanford team may post on the Stanford Staffers
listserv. Woebot exchanges an average of 1-2 million messages per week with its users. Woebot users have
indicated interest in substance use content. Specifically, 63% of current users (surveyed in July 2018)
reported interest in content related to substance use. In regards to their specific substance use behaviors over
the previous month, 22% of users reported having 5 or more alcoholic drinks in a row within a couple of
hours (i.e., binge use), and 5% endorsed using non-prescription drugs. Woebot Labs has used these channels
for previous research participation invitations with success.
Minor editing changes may be made to recruitment materials to enhance clarity.

a) For the following categories include a scientific estimate of the frequency, severity, and reversibility of potential
risks. Wherever possible, include statistical incidence of complications and the mortality rate of proposed
procedures. Where there has been insufficient time to accumulate significant data on risk, a statement to this
effect should be included. (In describing these risks in the consent form to the participant it is helpful to use
comparisons which are meaningful to persons unfamiliar with medical terminology.)
The risks of the Investigational devices.
N/A
The risks of the Investigational drugs. Information about risks can often be found in the Investigator's
brochure.
N/A
The risks of the Commercially available drugs, reagents or chemicals. Information about risks can
often be found in the package insert.
N/A
The risks of the Procedures to be performed. Include all investigational, non-investigational and
non-invasive procedures (e.g., surgery, blood draws, treadmill tests).
N/A
The risks of the Radioisotopes/radiation-producing machines (e.g., X-rays, CT scans, fluoroscopy) and
associated risks.
N/A
The risks of the Physical well-being.
N/A
The risks of the Psychological well-being.
Potential Upset due to Survey Questions: Foreseeable risks to subjects include the possibility that some
assessment questions and/or treatment procedures may be upsetting to subjects. Experience at Stanford with
similar populations has indicated that the risk of emotional upset during the assessments is low and if it
occurred, the upset would likely not be serious in nature and temporary. Such risks will be minimized by the
thoughtful selection of questionnaires. Potential participants will also be informed that they may drop out of
the study at any time and if requested, appropriate treatment referrals would then be given.
The risks of the Economic well-being.
N/A
The risks of the Social well-being.
Potential loss of confidentiality.

N/A
c)
Describe the planned procedures for protecting against and minimizing all potential risks. Include the
means for monitoring to detect hazards to the participant (and/or to a potential fetus if applicable).
Include steps to minimize risks to the confidentiality of identifiable information.
Given that the research aims to enroll a low-treatment seeking population, we do not envisage that
participation in the study will be associated with elevated risk. We are not assessing suicidal ideation in our
questionnaires. During the eligibility screener, those who have had a suicide attempt within the past year
will be excluded from the study. It is not feasible to confirm the responses by participants to the
questionnaires in real time. However, some risk is always present in studies that involve human participants.
Such risk may include the following:
1. Data Protection and Privacy: All study data are gathered on a HIPAA compliant web platform that resides
behind Stanford security firewalls and has been tried and tested by the University for several years, thus
actual risk from data breach for study data is low. All assessments, including the screening, four assessment
batteries, and mediator assessment will be administered via a HIPAA compliant survey administration tool
commonly used by Stanford University in its clinical trials (Qualtrics or REDCap). Given the high data
protection safeguards embedded within Qualtrics or REDCap, there is little risk to the subject associated in
regards to their privacy and/or confidentiality.
Research material obtained from human subjects will involve behavioral and psychological assessments
including self-report questionnaires. All data will be obtained specifically for purposes of this research
project. Data that is obtained from the Qualtrics or REDCap assessments will be stored and protected within
Qualtrics or REDCap. Data that is obtained via Woebot will be encrypted and stored on Amazon Web
Services (AWS); Woebot Labs data gathering and storage procedures are compliant with both the Health
Insurance Portability and Accountability Act (HIPAA) and the European Union's General Data Protection
Regulation (GDPR) compliant. Only members of the research team (PI, Co-PIs, biostatistician, research
assistant) will have access to the data.
2. Potential Upset due to Survey Questions: Foreseeable risks to subjects include the possibility that some
assessment questions and/or treatment procedures may be upsetting to subjects. Experience at Stanford with
similar populations has indicated that the risk of emotional upset during the assessments is low and if it
occurred, the upset would likely not be serious in nature and temporary. Such risks will be minimized by the
thoughtful selection of questionnaires. Potential participants will also be informed that they may drop out of
the study at any time and if requested, appropriate treatment referrals would then be given.
3. Risk of treatment avoidance due to engagement with either of the randomized interventions. In both
interventions it is explicitly stated that the service should not be used in place of traditional treatment. In the
case of the W-SUDs intervention, Woebot is designed to hold individuals accountable for pursuing
additional options in conditions of unchanged symptoms for a prolonged amount of time (4 weeks). In
addition, Woebot will invite the user to consider what seeking additional services would look like.
4. Risk of suicide: Woebot informs the participant that it is not designed for crisis service. Additionally,
Woebot detects crisis language (e.g. "want to kill") and asks to confirm it with the user. If the user confirms,
Woebot automatically, in real-time offers resources (9-1-1, suicide crisis hotlines, referral to ER). Woebot's
crisis detectors flags around 200 possible harm to self phrases, including about 10 misspellings and 5 slang
phrases. Woebot's data indicate that users do not use Woebot for crisis management; about 6.3% trigger the
safety net protocol, of which 27% confirm that it is indeed a crisis (i.e., for a true crisis rate of 1.7%).
Woebot's algorithm is over-sensitive, designed to over-detect, rather than under-detect to make sure that
cases are not missed. Woebot staff periodically check the data for true/false positive rates. Additionally, if
anyone is developing or indicating serious thoughts about suicide or harming themselves, it is best practice
to call 9-1-1 and/or go to the nearest ER.
d)
Explain the point at which the experiment will terminate. If appropriate, include the standards for the
termination of the participation of the individual participant Also discuss plans for ensuring necessary
medical or professional intervention in the event of adverse effects to the participants.

questions that assess for SAEs. More details about adverse events are in section e.
e)
Data Safety and Monitoring Plan (DSMP). See guidance on Data Safety and Monitoring.
A Data and Safety Monitoring Plan (DSMP) is required for studies that present Medium or High risk
to participants. (See Overall Evaluation of Risk above). If Low Risk, a DSMP may not be necessary.
Multi-site Phase III clinical trials funded by NIH require the DSM Plan to have a Data Safety
Monitoring Board or Committee (DSMC or DSMB). The FDA recommends that all multi-site clinical
trials that involve interventions that have potential for greater than minimal risk to study participants
also have a DSMB or DSMC.
The role of the DSMC or DSMB is to ensure the safety of participants by analyzing pooled data from
all sites, and to oversee the validity and integrity of the data. Depending on the degree of risk and the
complexity of the protocol, monitoring may be performed by an independent committee, a board
(DSMC/DSMB), a sponsor's Data Safety Committee (DSC), a Medical Monitor, a sponsor's safety
officer, or by the Protocol Director (PD).
Describe the following:
What type of data and/or events will be reviewed under the monitoring plan, e.g. adverse events,
protocol deviations, aggregate data?
The Data Safety and Monitoring Plan will include Woebot's standard safety net protocol as well as a
Data Safety and Monitoring Board overseen by Stanford University. Woebot's Safety Net Procedures
Study informed consent will state that Woebot is not a crisis program designed to address active suicidal
ideation or overdose. Woebot also conversationally informs first time users that it is not a crisis service.
Our current safety net protocol will be adapted for the proposed study. Woebot's crisis detectors flags
around 200 possible harm to self phrases, including about 10 misspellings and 5 slang phrases. Woebot
detects crisis language (e.g. "want to kill") and asks to confirm it with the user. If the user confirms,
Woebot offers resources (9-1-1, suicide crisis hotlines), carefully curated with expert consultation. Our
data indicate that users do not use Woebot for crisis management; about 6.3% trigger the safety net
protocol, with 27% confirming that it is indeed a crisis when Woebot asks to confirm (i.e., our true
positive rate). To make sure that we do not miss any cases, we over detect, rather than under detect. In
addition, we periodically check the data for true/false positive rates. Adverse Events We do not
anticipate that the use of the interventions will increase risk as outlined above. In addition, there is a
limited capacity to detect adverse events (such as overdose, suicide attempt or hospitalization related to
substance use or other) unless explicitly voluntarily reported by the participant. In the case Stanford
University and / or Woebot Labs becomes aware of an adverse event, the appropriate protocol, approved
by the DSMB and Stanford University's Institutional Review Board, will be immediately implemented.
This includes immediate notification of the IRB, DSMB, and NIH, and an immediate convening of the
DSMB to discuss requisite follow-up steps.
Identify who will be responsible for Data and Safety Monitoring for this study, e.g. Stanford
Cancer Institute DSMC, an independent monitoring committee, the sponsor, Stanford investigators
independent of the study, the PD, or other person(s).
To ensure the data protection and safety of research participants, Stanford University will serve as the
Data Coordinating Center for the study under the coordination of Drs. Biaocchi and Prochaska. They
will convene a group of three to serve as an oversight board with professional expertise in the area of the
study. Dr. Prochaska is an expert in the field of addiction and substance use, and Dr. Biaocchi has

10. Benefits
a)
Describe the potential benefit(s) to be gained by the participants or by the acquisition of important
knowledge which may benefit future participants, etc.
When evaluating the risks and benefits of the proposed study, it is
believed that risks are relatively minimal when compared to the potential therapeutic benefits that subjects
are likely to receive. The benefits of receiving W-SUDs include potentially reducing substance abuse,
acquiring practical psychotherapeutic skills (from cognitive behavioral therapy, motivational interviewing,
dialectical behavior therapy, and mindfulness), and receiving psychoeducation about substance abuse.
Participants who reduce substance abuse may derive additional benefits should reduction in substance abuse
be associated with other psychological improvements such as interpersonal or occupational functioning.
Study of the effectiveness of this intervention will also benefit society more generally by providing data on
the efficacy, utility, and cost-benefits of a W-SUDs, the first SUDs-focused digital therapeutic delivered by
an artificial intelligence (AI)-powered conversational agent.
11. Privacy and Confidentiality
Privacy Protections
a)
Describe how the conditions under which interactions will occur are adequate to protect the privacy
interests of participants (e.g., privacy of physical setting for interviews or data collection, protections
for follow-up interactions such as telephone, email and mail communications).
All assessments, including the screening and the two assessment batteries, will be administered via a
HIPAA compliant survey administration tool commonly used by Stanford University in its
clinical trials (Qualtrics or REDCap). Given the high data protection safeguards embedded within Qualtrics
and REDCap, there is little risk to the subject associated in regards to their privacy and/or confidentiality.
Research material obtained from human subjects will involve
behavioral and psychological assessments including self-report questionnaires. All data will be obtained
specifically for purposes of this research project. Data that is obtained from the Qualtrics or REDCap
assessments will be stored and protected within Qualtrics or REDCap. Data that is obtained via Woebot will
be encrypted and stored on Amazon Web Services (AWS); Woebot Labs data gathering and storage
procedures are compliant with both the Health Insurance Portability and Accountability Act (HIPAA) and
the European Union's General Data Protection Regulation (GDPR) compliant. Only members of the
research team (PI, Co-PIs, biostatistician, research assistant) will have access to the data.
Confidentiality Protections
b)
Specify PHI (Protected Health Information). PHI is health information linked to HIPAA identifiers
(see above). List BOTH health information AND HIPAA identifiers. If you are using STARR, use the
Data Privacy Attestation to ensure that your request will match your IRB-approved protocol. Be
consistent with information entered in section 15a.
Individual names, email addresses, phone numbers, dates of birth,
gender/biological sex, IP addresses (automatically collected through Qualtrics), and zip codes.
Drug Use Psychopathology
1. The Drug Abuse Screening Test 10 (DAST-10), a brief, 10-item self-report measure adapted from the
28-item DAST, assesses consequences related to drug abuse, excluding alcohol and tobacco. A score of 3
or higher indicates significant problems related to drug abuse. The DAST-10 demonstrated discriminate
validity between individuals (i) with lifetime drug use disorders and those without and (ii) who are current
abusers and those who are former abusers. It also has moderate level of test-retest and reliability as well as
sensitivity and specificity.
2. The Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) is a widely used 3-item
self-report screen for hazardous or harmful alcohol consumption that is based off of the 10-item original
AUDIT. Developed by the World Health Organization, the AUDIT has been tested extensively in

primary-care settings and various outpatient substance abuse treatment population, supporting the
application of this screener tool. The AUDIT-C has been tested and validated across racial groups.
6. The Drug Abstinence Self-Efficacy Scale (DASE) is a 12-item self-report scale, reflecting Bandura's
(1986) cognitive-behavioral self-efficacy theory, and is a shortened version of the original 20-item scale.
The 20-item scale has shown to be a reliable and valid measure of self-efficacy for drug use. The scale will
be adapted to refer to use of both drugs and alcohol, by including that language in the item stem.
General Psychopathology
3. The Patient Health Questionnaire (PHQ-9) is a brief 9-item scale used to determine the severity of
depression in medical populations. The PHQ-9 has high reliability across populations. We will not include
item #9 that assesses suicidal ideation.
4. The Generalized Anxiety Disorder (GAD-7) is a brief self-report scale that identifies the degree to which
an individual may have generalized anxiety disorder. This scale has good internal consistency, convergent
validity with depression, stress, and anxiety, and is a valid and efficient tool for GAD screening in clinical
and general populations.
Employee Health
5. The CAGE Adapted to Include Drug USE (CAGE-AID) was developed by the John Hopkins Dept of
Medicine. It's a brief instrument to measure problematic drug use. The CAGE-AID is designed to be an easy
yet effective way for primary care providers to determine if substance abuse exists and needs to be
addressed.
7. The Michigan Alcohol Screening Test (MAST), revised is a 22 question instrument to measure
problematic alcohol use. One of the most widely used measures for assessing alcohol abuse, the MAST is a
questionnaire designed to provide a rapid and effective screening for lifetime alcohol-related problems and
alcoholism. The MAST has been productively used in a variety of settings with varied populations.

13. 1
Consent
WOEBOT Consent form
Check if VA related
a)
Describe the informed consent process. Include the following.
i) Who is obtaining consent? (The person obtaining consent must be knowledgeable about the study.)
ii) When and where will consent be obtained?
iii) How much time will be devoted to consent discussion?
iv) Will these periods provide sufficient opportunity for the participant to consider whether or not to
participate and sign the written consent?
v) What steps are you taking to minimize the possibility of coercion and undue influence?
vi) If consent relates to children and if you have a reason for only one parent signing, provide that
rationale for IRB consideration.
Consent will be received via the mobile application wherever and whenever the participants choose and will
take approximately 5 minutes. This will provide sufficient opportunity for the participant to consider
whether or not to participate and sign the online consent since there will be no time limit. Study staff will
not be with the potential participant and there will be no possibility of coercion or undue influence. No
children will be recruited
b)
What is the Procedure to assess understanding of the information contained in the consent? How will
the information be provided to participants if they do not understand English or if they have a hearing
impairment? See HRPP Chapter12.2 for guidance.
Only English speaking participants will be recruited. The consent form will be readable so those with a
hearing impairment will still be able to access it.
c)
What steps are you taking to determine that potential participants are competent to participate in the
decision-making process? If your study may enroll adults who are unable to consent, describe (i) how
you will assess the capacity to consent, (ii) what provisions will be taken if the participant regains the
capacity to consent,(iii) who will be used as a legally authorized representative, and (iv) what
provisions will be made for the assent of the participant.
The consent form will only be accessible to those using a mobile application since that is the investigational
device. Participants will only include those competent to consent in the very low risk study.

rationale for IRB consideration.
(i)Study staff will be obtaining the consent via online questionnnaire (Qualtrics or REDCap). (ii)This
consent will be at the beginning of the screening questionnaire (Qualtrics or REDCap). Since consent is
obtained online, it can be obtained at any location of the participants choosing. (ii)There is no time limit-
each respondent can take much time as they want to read through the consent. Reading consent is
anticipated to not take more than five minutes. (iv)Since consent is obtained online, the participant may take
as much time as they wish to consider whether or not to participate and proceed with the screener. (v)No
incentive for form of coercion is present for the screening process. The study is voluntary; Participants are
informed that they can withdraw or choose not to participate at any time. There is no payment for going
through the screener. (vi)N/A.
b)
What is the Procedure to assess understanding of the information contained in the consent? How will
the information be provided to participants if they do not understand English or if they have a hearing
impairment? See HRPP Chapter12.2 for guidance.
We are not recruiting participants who cannot understand English.
c)
What steps are you taking to determine that potential participants are competent to participate in the
decision-making process? If your study may enroll adults who are unable to consent, describe (i) how
you will assess the capacity to consent, (ii) what provisions will be taken if the participant regains the
capacity to consent,(iii) who will be used as a legally authorized representative, and (iv) what
provisions will be made for the assent of the participant.
Participants will be reading the consent form before beginning the screener. Participants must be English
literate to participate as the questionnaires, consent forms, and Woebot app are only available in English.
The participant will have to select "Agree" to participate in the study. Contact information is also provided
