The relationship between sensory phenomena, obsessions and compulsions

You are being invited to take part in the above research study. To help you decide whether you would like to take part or not, it is important that you understand why the research is being done and what it will involve.

What is the research about?

I am Holly Bedford, this research project is part of my undergraduate BSc psychology degree. I am investigating the relationship between sensory phenomena, obsessions and compulsions. Sensory phenomena are uncomfortable bodily feelings that can precede compulsions in patients with obsessive compulsive disorder (OCD). Most research so far has focused on the direct relationship between sensory phenomena and compulsions. However, obsessions form a large component of OCD and may be temporally and meaningfully related to these sensory phenomena. A more specific question I will be looking at is if obsessions follow these physical sensory experiences.

Why have I been asked to participate?

You have been asked to participate because you are a member of the public and are over 18.

What will happen to me if I take part?

If you decide to participate in this study, you will be required to complete a survey that asks questions related to personal experiences of obsessions, compulsions and sensory phenomena.

The questionnaire is anonymous, can be completed on your own personal device at home and should take approximately 50 minutes. Once completed you will be provided with further details about this research area.

No further participation is required from you after you have completed the questionnaire.

Are there any benefits in my taking part?

Psychology students at the University of Southampton will be assigned 10 credits for completing the study. There are no direct benefits for taking part. However, your participation will add to our current understanding of the relationship between obsessions, sensory phenomena and compulsions.

Will my participation be confidential?

Your participation and the information we collect about you during the course of the research will be kept strictly confidential.

Please read the attached Information Sheet for more information. If you are happy to participate you will be asked to consent to take part.
