The Parasite and Infestation Study
Understanding the Experience of Patient-Physician Diagnostic Incongruency: I Know Something is Wrong But No One Believes Me
Many people have evidence of bugs, parasites, and infestation, but are told by others that they cannot find a cause. This distressing and frustrating experience can last for years, as the person seeks answers. The current study aims to understand the experience of these individuals. In a 1-2 hour session over Zoom, the investigators will ask participants questions about their experience, have them complete self-report questionnaires, and ask them to complete a few games on the computer. The investigators' goal is to help characterize and understand individuals with this experience to aid in better treatment and inform recommendations for providers.
調査の概要
状態
詳細な説明
The current study aims to characterize the experiences of people who have evidence of bugs, parasites, and/or infestation but are told by physicians or other professionals (e.g. vets, pest control) that there is nothing wrong. The investigators seek to understand the emotional and cognitive aspects of this experience, through semi-structured interviews, self-report questionnaires, and cognitive tasks. The study will take a few hours and is conducted remotely, allowing for participation regardless of the participant's physical location. There is practically no aggregate information on this experience, with most current information relying on case reports and medical record review. The investigators hope to provide greater insights into this experience to guide support for individuals going through this difficult process.
