About this study
Official title: Testing Target Engagement and Effectiveness of Web-based Interpretation Training For Anxiety
The study aims to develop a web-based Cognitive Bias Modification infrastructure to train interpretations, and evaluate the usability, acceptability, and feasibility of the program to reduce anxiety symptoms.
Read the detailed description
Approximately half of the U.S. population experiences serious mental health problems during their lifetime, including 29% with anxiety pathology severe enough to qualify for an anxiety disorder diagnosis [1]. Critically, more than two thirds of individuals struggling with a mental illness do not receive treatment [1]. With this level of mental illness burden, it is clear that treating people one-on-one in an office setting will never meet the existing needs [2]. There are many barriers to treatment, including costs [3], difficulties accessing evidence-based treatments in many regions [4], and associated stigma [5]. Thus, there is a pressing need to consider alternative, larger scale approaches to delivering mental health services. Cognitive Bias Modification (CBM) interventions hold considerable promise as a way to meet these needs, especially for anxiety difficulties [6]. These computer-based programs are designed to alter biased ways of thinking, such as a tendency toward negative interpretations, which cause and maintain anxiety [6]. Because these programs do not require therapist contact and can be administered on any computer with an Internet connection, CBM holds promise as a cost-effective method that can be disseminated widely. However, while CBM for interpretation bias (CBM-I) has established efficacy when administered in-person in the laboratory [7], it now needs to be tested with broader populations using a web-based infrastructure to examine: a) whether the program will be effective in a web environment, b) whether the program continues to engage the targeted mechanism (i.e., interpretation bias), c) the feasibility of this delivery method, and d) the modifications needed to adapt the program for the web (in particular, to prime anxiety-linked negative thinking in an online environment, we test the effect of adding a guided anxious imagery exercise to prime feared outcomes prior to each training session).
Together, the current proposal will develop an infrastructure to pilot test the effectiveness of web-based CBM-I for anxiety symptoms. CBM-I training will target moderate to severe anxiety symptoms, a widespread problem area with considerable occupational and social impairment [8]. Participants will be visitors to Project Implicit Mental Health (PIMH), an existing website directed by the Principal Investigator that allows visitors to assess their cognitive biases tied to mental health concerns. Consistent with the RFA's priorities, this approach encourages efficiencies by capitalizing on the existing PIMH site and its heavy traffic. Further, the site's large number of visitors and use of automated assessments will make it efficient to assess baseline demographic characteristics and interpretation bias as moderators of CBM-I effects that can be tested in future trials.
Aim 1: Develop and evaluate usability and acceptability of web-based CBM-I for anxiety symptoms.
Aim 1 will build the web-based interpretation bias training program using the PIMH infrastructure. We will pilot the program on a small test group of moderate to highly anxious participants (N=15) who will complete questionnaires and semi-structured interviews to provide feedback on the programs' usability and acceptability. Further, an advisory board (N=8) of anxiety researchers, clinicians, and experts in CBM and web-based research will provide feedback on the program and study protocol. Using a "deployment-focused" approach, this feedback from experts and end-users will be used to iteratively modify the program for the trial planned for Aims 2 and 3. Thus, even at this initial pilot stage, we will measure the targeted outcome (anxiety symptoms) and mechanism (interpretation bias) to determine whether modifications to enhance target engagement are needed. Note, within Research Domain Criteria (RDoC), this outcome falls under the Potential Threat/Anxiety construct within the Negative Valence System, and the targeted mechanism (interpretation bias) falls under the Response Selection, Inhibition construct within the Cognitive (effortful) control system. Both the outcome and mechanism will be objectively measured using multiple units of analysis (e.g., behavior and self-report). Further, mechanisms underlying the guided anxious imagery prime's effects will be measured by assessing subjective distress, imagery vividness, and activation of feared outcomes following the manipulation. This prime was selected in part because of its potential to be disseminated widely in future trials, given it does not require human contact.
Aim 2: Test target engagement, feasibility and effectiveness of web-based CBM-I.
Aim 3: Evaluate the impact of an anxious prime on web-based CBM-I for anxiety symptoms.
Aims 2 and 3 will test the feasibility of an 8-session web-based interpretation training program among individuals with moderate to severe anxiety symptoms (based on screening at the PIMH site). Participants will be randomly assigned to positive CBM-I (90% positive scenario training), 50% positive/50% negative CBM-I, or a no scenario control condition. Half the participants in each of these 3 conditions will receive an anxious imagery prime prior to each training session, and half will receive a neutral imagery prime, resulting in a 3 training condition x 2 prime design (N=210; target of n=35 per condition). Feasibility will be determined by analyses of recruitment, attrition, acceptance of randomization, adherence to and appropriateness of the measurement model, caseness, extent of missing data, and safety. Additionally, target engagement (change in interpretation bias) and preliminary tests of effectiveness at reducing anxiety symptoms will be evaluated.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Positive Cognitive Bias Modification - InterpretationBehavioural
Also called Ambiguous Scenarios Training
Training involves presenting participants with brief scenarios that introduce an ambiguous potential threat. Critically, the ambiguity regarding how the situation is resolved remains until the last word of the scenario, which is presented as a word fragment that the participant must solve, which will then assign a benign (rather than threatening) meaning to the scenario.
50/50 Cognitive Bias Modification - InterpretationBehavioural
This condition follows the same design and content as the Positive Training conditions, except the word fragments differ; rather than consistently resolving the scenario in a positive direction, half of the scenarios will end with a negative (anxiety-congruent) word fragment, and half will end with a positive word fragment.
Anxious Imagery PrimeBehavioural
We will test whether priming anxious concerns and feared negative outcomes on the web via the addition of a guided anxious imagery prime at the start of each session will enhance effects.
Neutral Imagery PrimeBehavioural
At the start of each session, participants will complete a neutral control imagery exercise where they do a guided imagery exercise imagining upcoming mundane tasks, like brushing one's teeth.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Recognition Ratings (Positive Interpretation Bias)
To measure interpretation bias, participants will read ambiguous scenarios with titles, after which they will see the titles of each scenario, followed by 2 disambiguated interpretations of the scenario: 1 positive and 1 negative. Participants will rate each disambiguated interpretation based on how similar in meaning it is to the original scenario on a 4-point scale ranging from 1 to 4. The mean of the positive, threat-related ratings index positive interpretation bias. Higher scores represent a more positive interpretation bias.
Measured: Baseline, and after sessions 3 (~2 weeks following baseline), 6 (~10 days after session 3), and 8 (~7 days after session 6) & at 2-month follow-up. Measure will be completed immediately following that day's training session.
Change in Overall Anxiety Severity and Impairment Scale
The Overall Anxiety Severity and Impairment Scale (OASIS; Norman, Hami Cissell, Means-Christensen, \& Stein, 2006) assesses anxiety frequency, severity, and associated avoidance, work and social interference. This 5-item measure of anxiety symptom severity and impairment has good psychometric properties, shows treatment sensitivity, and is valid in community and clinical samples. All items are rated on a scale of 0 (lowest impairment/severity) to 4 (highest impairment/severity). Total scores on the OASIS are calculated by summing the scores of each of the 5 questions. The total score on the OASIS ranges from 0 to 20, with higher scores indicating greater anxiety. A cut-score of 8 or higher on the OASIS is considered to indicate probable anxiety disorder.
Measured: Baseline, and after sessions 1,2,3,4,5,6,7,8 (sessions will be spaced ~3-4 days apart) & at 2-month follow-up. Measure will be completed immediately following that day's training session. Session 2 is expected to occur within 3-8 days of the baseline.
Change in Recognition Ratings (Negative Interpretation Bias)
To measure interpretation bias, participants will read ambiguous scenarios with titles, after which they will see the titles of each scenario, followed by 2 disambiguated interpretations of the scenario: 1 positive and 1 negative. Participants will rate each disambiguated interpretation based on how similar in meaning it is to the original scenario on a 4-point scale ranging from 1 to 4. The mean of the negative, threat-related ratings index negative interpretation bias. Higher scores represent a more negative interpretation bias.
Measured: Baseline, and after sessions 3 (~2 weeks following baseline), 6 (~10 days after session 3), and 8 (~7 days after session 6) & at 2-month follow-up. Measure will be completed immediately following that day's training session.
Change in Brief Bodily Sensations Interpretations Questionnaire
The Brief Bodily Sensation Interpretation Questionnaire (BBSIQ; Clark et al., 1997) was administered as a more independent, additional measure of interpretation bias. In the BBSIQ, participants are presented with fourteen ambiguous events related to physical (e.g., feeling lightheaded) or external (e.g., smelling smoke, social situations) concerns, along with three possible explanations for each ambiguous event (one negative, and two neutral or positive explanations). Participants rated the extent to which they believed each explanation for why the ambiguous event occurred on a Likert scale from 0 ("not at all likely") to 4 ("extremely likely"). Typically, the BBSIQ is administered on an eight-point Likert scale, but a 0-4 scale was used to align with other rating scales in the study. Negative interpretation bias score was computed by averaging the likelihood ratings for all negative explanations (following Steinman \& Teachman, 2010, 2015).
Measured: Baseline, and after sessions 3 (~2 weeks following baseline), 6 (~10 days after session 3), and 8 (~7 days after session 6) & at 2-month follow-up. Measure will be completed immediately following that day's training session.
Secondary outcomes (4)
Multi-Session User Experience Questionnaire
This questionnaire assesses users' opinions about the intervention. Participants could select from options "Not at all=0, Slightly=1, Somewhat=2, Mostly=3, Very=4, Decline to answer=5" for questions 1-13 as well as 15 and 16 (examples listed below); question 14 asked "This training program was 8 sessions. How many sessions do you think would have been ideal?" with an open ended response box, which we will not include in the means and SDs. We will recode "Decline to answer=5" as NA. Higher scores on this scale indicate more positive experiences with the program in general across questions, from 0-4.
- How helpful did you find the web program for reducing your anxiety?
- How much did the web program improve your overall quality of life?
- How much did the web program help improve your overall mood (e.g., feeling happier)?
- How likely would you be to recommend this web program to others with similar anxiety difficulties?
- How easy was the web program to use?
Measured: At 2-month follow-up
Impact of Anxious Imagery Prime (Change Over Time is Exploratory But Should Show Anxious/Neutral Prime Differences; e.g., in Subjective Distress)
Following the anxious or neutral imagery prime, participants reported on the questions provided. Minimum score = 3; maximum score =115. Higher scores indicate more vividness and anxiety following the anxious imagery prime.
How vividly did you imagine the situation?
1=Not at all vivid 2=Somewhat vivid 3=Moderately vivid 4=Very vivid 5=Totally vivid
How anxious did you feel (at the highest level of anxiety) as you completed the imagery task? (using a 0-100 slider with the following anchors marked) 0=Not at all anxious, 50= Moderately anxious, 100=Totally anxious
How likely is it that this situation will turn out well vs. turn out badly? 1=Very likely to turn out well, 2=Somewhat likely to turn out well, 3=Neutral, 4= Somewhat likely to turn out badly, 5= Very likely to turn out badly
If this situation did turn out badly, how well or badly would you be able to handle it?
1=Very well, 2=Somewhat well, 3=Neutral, 4=Somewhat badly, 5=Very badly
Measured: After sessions 1,2,3,4,5,6,7,8 (sessions will be spaced ~3-4 days apart). Measure will be completed following that day's imagery prime (which immediately precedes the training session).
Change in Depression, Anxiety, Stress Scales-Short Form: Anxiety Subscale
While we use the OASIS as a primary measure of anxiety symptom severity, we are using the DASS-AS (Lovibond \& Lovibond, 1995) as another 7-item measure of anxiety symptoms. Higher scores indicate more severe anxiety symptoms. Minimum score = 0; maximum score = 21.
0 = Did not apply to me at all
- = Applied to me to some degree, or some of the time
- = Applied to me to a considerable degree, or a good part of time
- = Applied to me very much, or most of the time
Qs:
- I was aware of dryness of my mouth.
- I experienced breathing difficulty (e.g., excessively rapid breathing, breathlessness in the absence of physical exertion).
- I experienced trembling (e.g., in the hands).
- I was worried about situations in which I might panic and make a fool of myself.
- I felt I was close to panic.
- I was aware of the action of my heart in the absence of physical exertion (e.g., sense of heart rate increase, heart missing a beat).
- I felt scared without any good reason.
Measured: Baseline, after session 8 (~4 weeks after baseline) & at 2-month follow-up.
Change in Quality of Life Scale
The Quality of Life Scale (Flanagan, 1978) is a 16-item questionnaire chosen to evaluate change in quality of life in five domains: recreation, relationships, well-being, personal fulfillment and development, and social activities. Higher scores indicate more positive feelings about quality of life/more satisfaction. Minimum score = 16; maximum score = 80.
The question asks "How satisfied are you with..." with each of the following options as separate questions: material, health, relationships, children, spouse, friend, helping, participating, learning, understanding, work, expression, socializing, reading, recreation, independence (just providing a key word for purposes of description, but questions include a full statement such as "Material comforts home, food, conveniences, financial security " for material).
Response options range from Completely unsatisfied=1, Somewhat unsatisfied=2, Mixed=3, Somewhat satisfied=4, Completely satisfied=5.
Measured: Baseline, and after sessions 3 (~2 weeks following baseline), 6 (~10 days after session 3), and 8 (~7 days after session 6) & at 2-month follow-up. Measure will be completed immediately following that day's training session.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The study aims to develop a web-based Cognitive Bias Modification infrastructure to train interpretations, and evaluate the usability, acceptability, and feasibility of the program to reduce anxiety symptoms.
Detailed description
Approximately half of the U.S. population experiences serious mental health problems during their lifetime, including 29% with anxiety pathology severe enough to qualify for an anxiety disorder diagnosis [1]. Critically, more than two thirds of individuals struggling with a mental illness do not receive treatment [1]. With this level of mental illness burden, it is clear that treating people one-on-one in an office setting will never meet the existing needs [2]. There are many barriers to treatment, including costs [3], difficulties accessing evidence-based treatments in many regions [4], and associated stigma [5].

Aims 2 and 3 will test the feasibility of an 8-session web-based interpretation training program among individuals with moderate to severe anxiety symptoms (based on screening at the PIMH site). Participants will be randomly assigned to positive CBM-I (90% positive scenario training), 50% positive/50% negative CBM-I, or a no scenario control condition. Half the participants in each of these 3 conditions will receive an anxious imagery prime prior to each training session, and half will receive a neutral imagery prime, resulting in a 3 training condition x 2 prime design (N=210; target of n=35 per condition). Feasibility will be determined by analyses of recruitment, attrition, acceptance of randomization, adherence to and appropriateness of the measurement model, caseness, extent of missing data, and safety. Additionally, target engagement (change in interpretation bias) and preliminary tests of effectiveness at reducing anxiety symptoms will be evaluated.

Primary outcome
Change in Recognition Ratings (Positive Interpretation Bias)
Time frame: Baseline, and after sessions 3 (~2 weeks following baseline), 6 (~10 days after session 3), and 8 (~7 days after session 6) & at 2-month follow-up. Measure will be completed immediately following that day's training session.
To measure interpretation bias, participants will read ambiguous scenarios with titles, after which they will see the titles of each scenario, followed by 2 disambiguated interpretations of the scenario: 1 positive and 1 negative. Participants will rate each disambiguated interpretation based on how similar in meaning it is to the original scenario on a 4-point scale ranging from 1 to 4. The mean of the positive, threat-related ratings index positive interpretation bias. Higher scores represent a more positive interpretation bias.
Change in Overall Anxiety Severity and Impairment Scale
Time frame: Baseline, and after sessions 1,2,3,4,5,6,7,8 (sessions will be spaced ~3-4 days apart) & at 2-month follow-up. Measure will be completed immediately following that day's training session. Session 2 is expected to occur within 3-8 days of the baseline.

The Brief Bodily Sensation Interpretation Questionnaire (BBSIQ; Clark et al., 1997) was administered as a more independent, additional measure of interpretation bias. In the BBSIQ, participants are presented with fourteen ambiguous events related to physical (e.g., feeling lightheaded) or external (e.g., smelling smoke, social situations) concerns, along with three possible explanations for each ambiguous event (one negative, and two neutral or positive explanations). Participants rated the extent to which they believed each explanation for why the ambiguous event occurred on a Likert scale from 0 ("not at all likely") to 4 ("extremely likely"). Typically, the BBSIQ is administered on an eight-point Likert scale, but a 0-4 scale was used to align with other rating scales in the study. Negative interpretation bias score was computed by averaging the likelihood ratings for all negative explanations (following Steinman \& Teachman, 2010, 2015).
4 secondary outcomes
Multi-Session User Experience Questionnaire
Time frame: At 2-month follow-up
Impact of Anxious Imagery Prime (Change Over Time is Exploratory But Should Show Anxious/Neutral Prime Differences; e.g., in Subjective Distress)
Time frame: After sessions 1,2,3,4,5,6,7,8 (sessions will be spaced ~3-4 days apart). Measure will be completed following that day's imagery prime (which immediately precedes the training session).
Change in Depression, Anxiety, Stress Scales-Short Form: Anxiety Subscale
Time frame: Baseline, after session 8 (~4 weeks after baseline) & at 2-month follow-up.
Change in Quality of Life Scale
Time frame: Baseline, and after sessions 3 (~2 weeks following baseline), 6 (~10 days after session 3), and 8 (~7 days after session 6) & at 2-month follow-up. Measure will be completed immediately following that day's training session.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 20 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 20 Feb 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Recognition Ratings (Positive Interpretation Bias) (time frame: Baseline, and after sessions 3 (~2 weeks following baseline), 6 (~10 days after session 3), and 8 (~7 days after session 6) & at 2-month follow-up. Measure will be completed immediately following that day's training session.). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02382003, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
