Many earlier studies conducted on sports betting and addiction have examined sports betting in the context of gambling and have not taken into account the specific motivations of sports betting. Therefore, the effects of motivational elements of sports betting on sports betting addiction risk are unknown. The aim of the present study was to examine the effects of motivation factors specific to sports betting on sports betting addiction. Accordingly, three linked studies were conducted. Firstly, to determine sports betting motivations “Sports Betting Motivation Scale (SBMS)” developed and validated. Secondly, to determine the risks of sports betting addiction “Problem Sports Betting Severity Index (PSBSI)” was adapted from Problem Gambling Severity Index (PGSI). Finally, the third study examined effects of the sports betting motivations on sports betting addiction risk. Study one (n=281), study two comprised (n=230), and the final study comprised (n=643) sports fans who bet on sports regularly for 12 months with different motivations. The findings demonstrate that the SBMS appears to be a reliable and valid instrument for assessing sports betting motivations. Also, the findings provided PSBSI validity for the use of the Turkish and sports betting adapted version of PGSI. As a result of the main research, “make money,” “socialization,” and “being in the game” motivations were found to be positive predictors of sports betting addiction risk, while “fun” motivation was a negative predictor. The motivations “recreation/escape,” “knowledge of the game,” and “interest in sport” were found not to be significant predictors of the risk of sports betting addiction.

许多早期关于体育博彩和成瘾的研究已经在赌博的背景下研究了体育博彩，并没有考虑到体育博彩的具体动机。因此，体育博彩的动机因素对体育博彩成瘾风险的影响尚不清楚。本研究的目的是检查特定于体育博彩的动机因素对体育博彩成瘾的影响。因此，进行了三项相关研究。首先，为了确定体育博彩动机，制定并验证了“体育博彩动机量表（SBMS）”。其次，为了确定体育博彩成瘾的风险，“问题体育博彩严重程度指数（PSBSI）”改编自问题赌博严重程度指数（PGSI）。最后，第三项研究检查了体育博彩动机对体育博彩成瘾风险的影响。学习一（n = 281），研究二包括（n = 230），最终研究包括（n=643) 12 个月内以不同的动机定期投注体育运动的体育迷。研究结果表明，SBMS 似乎是评估体育博彩动机的可靠且有效的工具。此外，研究结果提供了使用土耳其语和体育博彩改编版 PGSI 的 PSBSI 有效性。作为主要研究的结果，发现“赚钱”、“社交”和“参与游戏”动机是体育博彩成瘾风险的积极预测因素，而“有趣”动机是消极预测因素。发现“娱乐/逃避”、“游戏知识”和“对运动的兴趣”的动机不是体育博彩成瘾风险的重要预测因素。
