Objective: The general public has aversion toward professional basketball players' misbehaviors due to alcohol abuse, yet few ever try to uncover the reasons. This study intends to explore the behaviors and motivations for SBL basketball players, probing into a wide range of variants to see if there is any difference between ages, levels of basketball skills, marriage condition, income and etc. Method: The study combines a questionnaire collecting information like ages, level of basketball skills, marriage condition, incomes among players, a drinking behavior investigation and a drinking motivation measurement. Finally, the study employs T-Test and Single-Variant Analysis to discuss the difference in drinking behavior and drinking motivation among players under different variants. Conclusion: Statistics have shown that more than 90 percent of athletes have used alcohol and 88.2 percent of basketball players have used alcohol for the past 3 months. However, among the different variants' tables, only the table of ages exhibits a noticeable difference, other variants display only slight differences. So does Single-Variant Analysis. The study also has shown that a young player could score the highest points both in drinking behavior measurement and drinking motivation measurement. On the other hand, unlike young player, a start-line player or a national basketball team player or high lever income player has a better self-management and scores low points in these tables. This paper intends to uncover the reasons of a professional athlete's drinking behaviors and motivations, aiming to act as a prevention reference for the future generation of junior colleges basketball players.
