About this study

Official title: Combined Cognitive Bias Modification for Perfectionism and Intolerance to Uncertainty: A Randomized Controlled Trial

This study will examine the impact of cognitive bias modification (CBM) on perfectionism and intolerance to uncertainty. Undergraduate students will be recruited and randomly assigned to either experimental or placebo-control groups. Each group will attend four sessions of CBM over four weeks.

Read the detailed description

Background. Cognitive bias modification (CBM) is an intervention aiming to systematically change the biases in cognitive processing using experimental paradigms. CBM was found effective with a variety of disorders and transdiagnostic variables. Although there are few studies focusing on transdiagnostic variables like perfectionism and intolerance to uncertainty, further research needs to be done for the generalizability of these results. It was aimed in this study to test the effectiveness of CBM for perfectionism and intolerance to uncertainty with a sample of undergraduate students in Turkey.

Sample size was determined using G*power for a medium to large effect size based on previous studies and it was planned to include 28 undergraduate students who have a score of >70.5 in the Brief Symptom Measure in the study. Participants will get either 3-course credits or a 100 TL bookstore gift card for their full participation. After getting informed consent from participants, they will be randomized to either active or control condition. Participants will be blind to their intervention condition. Following randomization, baseline measurements will be collected. After the baseline measures were collected, links for interventions will be e-mailed to the participants according to their assigned group. Participants will get an email including the link for the study every week. Interpretation bias scores of participants for perfectionism and intolerance to uncertainty will be collected before the first intervention session and after the last intervention session. These sessions will last approximately 25 min. Participants will attend the session without an assessment in the second and third week and these sessions will last approximately 15 min. After four sessions, post-tests will be sent to the participants. Questionnaires will also be collected one month after the intervention was done.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Cognitive Bias ModificationBehavioural

    There will be four sessions of CBM. Each session will consist of two different part. The first part of the intervention will be the training based on the ambiguous scenario paradigm for perfectionism developed by Dodd (2019). Participants will need to complete word fragments in the last part of the scenario to resolve the ambiguity of the scenario. Then, a comprehension question will be presented to them to underscore the interpretation condition. Feedback will be given after each question. For the second part of the intervention aimed to intervene intolerance to uncertainty, word sentence association paradigm for intolerance to uncertainty developed by Oglesby (2017) will be used. In this intervention, participants will be asked to judge the relatedness of words and sentences which will be presented to them. Feedback will be given after each word-sentence.

  • Cognitive Bias Modification for Control GroupBehavioural

    For the first part of the intervention, the control group will be presented with the same procedures as the active group; however, feedbacks will be given to resolve the scenarios in a neutral way. When it comes to the second part of the intervention, different word-sentence pairings will be presented to the control group.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Brief Symptom Measure

    Psychiatric symptomatology will be assessed with Brief Symptom Measure consists of 25 items scored 1-7. Greater score means greater severity.

    Measured: Weeks 0, 4, 8

Secondary outcomes (5)
  1. Change in Interpretation bias for perfectionism

    Participants will read ten scenarios and rate the relatedness of four sentences for each scenario.

    Measured: Weeks 0, 4

  2. Change in Interpretation bias for intolerance to uncertainty

    Participants will judge the relatedness of word-sentence pairings. 40 pairings will be presented and each participant will have a score between 0 and 1. A score closer to 0 indicates severity of interpretation bias for intolerance to uncertainty.

    Measured: Weeks 0, 4

  3. Change in Frost Multidimensional Perfectionism Scale

    Self-report questionnaire of perfectionism consists of 35 items on a 5-point scale. Higher score means greater perfectionism.

    Measured: Weeks 0, 4, 8

  4. Change in Intolerance of Uncertainty Scale

    Self-report questionnaire of intolerance to uncertainty consists of 26 items on a 5-point scale. Higher score means greater intolerance to uncertainty.

    Measured: Weeks 0, 4, 8

  5. Change in Cognitive-Behavioral Avoidance Scale

    Self-report questionnaire of cognitive-behavioral avoidance consists of 31 items on a 5-point scale. Higher score means greater cognitive-behavioral avoidance.

    Measured: Weeks 0, 4, 8

Questions about this trial

What is this clinical trial studying?

A study testing Cognitive Bias Modification in people with Perfectionism and Intolerance to Uncertainty, run by Istanbul Sabahattin Zaim University at 1 site in United States.

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 5 inclusion and 2 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 26 Aug 2022. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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 Brief Symptom Measure (time frame: Weeks 0, 4, 8). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Aug 2022.
