Online Study: Thought Impact Scale, University of North Carolina, May 2017

The following online study conducted by Olafur Palsson, PsyD, psychologist, professor and researcher at the University of North Carolina Center for Functional GI and Motility Disorders, Chapel Hill, North Carolina, was received recently via social media. Dr. Palsson is a leading international researcher of IBS and its psychological aspects. The current study is not specific to IBS or any other chronic medical condition, and study volunteers need not have a medical condition, but if the Thought Impact Scale is validated through this and other research, it has potential applications for psychological interventions for IBS and other conditions.

Dr. Palsson is seeking adult volunteers aged 18 or over who are fluent in English and reside in the United States to complete two 25 minute surveys 30 days apart. You must be willing to provide him with your first name and an email address so that he can send a participant code number and password, but responses to the surveys themselves are anonymous and cannot be linked in the study database to personally identifying information.

The italicized paragraphs below are a direct, complete quotation of the details available on the study website, which is linked below the italicized portion. The website also includes a video of Dr. Palsson personally describing the intended research.  Please address any additional questions or concerns about the study directly to Dr. Palsson at

Dr. Olafur Palsson in the University of North Carolina at Chapel Hill School of Medicine is testing a new questionnaire, called the Thought Impact Scale, which is designed to measure the degree to which subconscious (or non-conscious) mental functions affect people’s conscious behaviors, feelings and life experiences in everyday life. This online study will evaluate how the new questionnaire scores relates to various personal life experiences and characteristics, and assess the reliability and internal consistency of the questionnaire.
Whether you believe you are influenced a lot by your subconscious mind or only a little bit or even not at all, you are invited to participate in this study.

Participation requires:

Completing online surveys twice, about 30 days apart (takes about 25 minutes each time).
Being at least 18 years old, living in the United States and being fluent in English.

Receive a personal report of your questionnaire results and their meaning. This report will include your scores on the new Thought Impact Scale and other questionnaires used in the study, how those scores compare in general with those of people in the study sample, and what the scores seem to mean about how much connection you have with your subconscious mind and how they relate to other main findings in the study.
