Reuben A. Buford May has been working alongside statisticians out of University of Pennsylvania on topics in sport. They recently published an article titled "Retrospective survey of youth sports participation: Development and assessment of reliability using school records." The article is focused on methods for assessing retrospective self-reports of sport participation. For the full article click here.

Abstract: "Many youths participate in sports, and it is of interest to understand the impact of youth sports participation on later-life outcomes. However, prospective studies take a long time to complete and retrospective studies may be more practical and time-efficient to address some questions. We pilot a retrospective survey of youth sports participation and examine agreement between respondent’s self-reported participation with high school records in a sample of 84 adults who graduated from high school between 1948 and 2018. The percent agreement between our survey and the school resources for individual sports ranged between 91.5% and 100%. These findings provide preliminary evidence for the reliability of retrospective self-report of youth sports participation. This survey may serve as an efficient approach for evaluating relationships between involvement in youth sports and health outcomes later in adulthood."
