Outcome Measures

Primary Outcomes (4)

  • 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.

    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.

    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.

    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).

    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

    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)

    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

    Baseline, after session 8 (~4 weeks after baseline) & at 2-month follow-up.

  • Change in Quality of Life Scale

    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.

Interventions

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.

Also known as: Ambiguous Scenarios Training
Positive Training+Anxious Imagery PrimePositive Training+Neutral Imagery Prime

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.

50/50 Training+Anxious Imagery Prime50/50 Training+Neutral Imagery Prime

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.

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.
