Reliability of Self-reported Concussion History in Current Rugby Union Players

Completed

• Conditions: Concussion, Mild

• Registration Number: NCT03544372
• Lead Sponsor: University of Dublin, Trinity College

Brief Summary

Perhaps no issue in sports medicine has attracted so much media attention and academic interest in recent years as the potential long-term neurodegenerative sequelae of sports-related concussion on athlete's brain health. Rugby has a high incidence of concussion. Recent research findings from a cohort of former professional players found that the number of concussions sustained during their professional careers was associated with the rate of diagnosed clinical depression and late-life cognitive impairment. A limitation of these studies is the use of a self-reported history of concussion. The reliability of professional rugby players to recall and self-report concussion history has never been quantified in the literature to date. Imperfect recall can generate bias in epidemiologic studies when the proportion of events recalled is associated with the health end points of interest. Associations observed may be spurious and due to recall bias if athletes differ in their knowledge and recognition of concussion symptomology in a manner that is associated with the health outcome of interest ie. under/overreporting of concussion. It is difficult to estimate the magnitude of the bias in the absence of any "gold-standard" measure of concussion history. Due to these concerns about the quality of self-reported concussion history, the investigators considered that it was important to evaluate the reliability of self-reported concussion history.

Detailed Description

The primary aim of this study is to investigate the reliability of self-reported concussion history in current rugby union players

Objectives:

The objectives will be to:

Investigate player's self-report history of sports-related concussion (number and nature of concussions) in this elite rugby playing group.

Correlate player self-report with established individual player medical data. Repeat this process approximately 6 months later on a sub sample of this cohort, in order to test the reliability of player's reported concussion.

Primary Outcome Measures

Name	Time	Method
Self-report Concussion History	30 minutes	reliability study, agreement between self-report history of concussion via the NIH concussion history tool and documented concussion history. The higher the intraclass correlation between the two-the greater the reliability of the NIH concussion tool
