The findings were as follows: First, leisure identity had wielded an influence on leisure flow. Second, leisure identity had an influence on leisure satisfaction. Third, leisure identity had an influence on re-participation intention. Fourth, leisure flow did not have any significant influence on leisure satisfaction.
