Recent Experiences With Concussions

Recent Experiences and Presentation Format: Study of Concussion Symptom Elicitation

College athletes will be recruited to complete a voluntary online survey that will take approximately 10 minutes. In this survey, they will answer a series of questions related to the concussion symptoms they have experienced in their recent sports season, their opinions related to concussions and concussion treatment, and demographics.

Detailed Description

College athletes will be recruited to complete a voluntary online survey that will take approximately 10 minutes. In this survey, they will answer a series of questions related to the concussion symptoms they have experienced in their recent sports season, their opinions related to concussions and concussion treatment, and demographics.

Of interest, participants will indicate what concussion symptoms they have recently experienced in one of four formats, to which they will be randomly assigned. Participants will either *check the symptoms they have experienced, *check the symptoms they have not experienced, *uncheck the symptoms they have experienced, or *uncheck the symptoms they have not experienced. It is believed that an alternative method of reporting symptoms that requires participants to indicate the symptoms they have not experienced will lead them to report having experienced a greater number of symptoms, based on past research regarding inclusion vs. exclusion modes of thought.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Check symptoms one has experienced; This is the baseline condition. When asked to indicate concussion symptoms (or most other kinds of symptoms for medical conditions), people usually place a check mark next to each symptom they have experienced.	Other: Symptom elicitiation; Survey procedure, people check or uncheck symptoms they have or haven't experienced. We randomly assign participants to only one of these symptom elicitation procedures.
Experimental: Check symptoms one has not experienced; Participants place a check mark next to each symptom they have NOT experienced in the most recent sports season.	Other: Symptom elicitiation; Survey procedure, people check or uncheck symptoms they have or haven't experienced. We randomly assign participants to only one of these symptom elicitation procedures.
Experimental: Uncheck symptoms one has experienced; To begin, all symptoms will be automatically checked. Participants are told to remove a check mark from each symptom they have experienced in the most recent sports season.	Other: Symptom elicitiation; Survey procedure, people check or uncheck symptoms they have or haven't experienced. We randomly assign participants to only one of these symptom elicitation procedures.
Experimental: Uncheck symptoms one has not experienced.; To begin, all symptoms will be automatically checked.
