Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Active Cognitive Bias Modification Group

This group of participants will receive 4 sessions of CBM targeting their interpretation biases for perfectionism and intolerance to uncertainty.

Group Type EXPERIMENTAL

Cognitive Bias Modification

Intervention Type BEHAVIORAL

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.

Placebo-Control Cognitive Bias Modification Group

This group of participants will receive 4 sessions of inactive CBM.

Group Type PLACEBO_COMPARATOR

Cognitive Bias Modification for Control Group

Intervention Type BEHAVIORAL

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.
