Data were collected during the playing season on the same night, each fortnight (11 occasions). Therefore, each occasion reflects a 2-week period.
*Not all participants responded on every occasion. Due to the deidentified nature of the study, if a player missed an occasion, a response was unable to be captured. A total of 614 responses were captured.
