Tóm tắt	The Sport Commitment Model explains why people keep participating in a sport by treating commitment as a psychological state -- the desire and resolve to continue -- that is produced by a small set of measurable determinants. Introduced by Tara Scanlan and colleagues in 1993, the model proposes that commitment rises with sport enjoyment, personal investments, involvement opportunities, and social constraints, and falls as attractive alternatives to involvement increase. Each determinant is a latent factor measured by self-report items, and commitment itself is a latent outcome predicted by their combination, making the model a structural account of motivation that can be tested with questionnaires and structural equation modelling. Because commitment in turn predicts persistence, the model links the psychology of why athletes stay engaged to the behavior of actually continuing to take part.	The Leisure Motivation Scale (LMS), developed by Jacob Beard and Mounir Ragheb in their 1983 Journal of Leisure Research article, measures the psychological and social reasons people give for participating in leisure. Building on Maslow's need theory and the leisure-needs literature, the scale reduces leisure motivation to four broad motives, each represented by twelve items: the intellectual motive (mental activity — learning, exploring, imagining), the social motive (friendship and interpersonal relationships, including the need for esteem), the competence-mastery motive (achievement, challenge, and the testing of skills), and the stimulus-avoidance motive (the drive to escape and to seek rest, solitude, and relaxation). Administered to 1,205 respondents and refined by item and factor analysis, the four subscales achieved reliabilities near .90 and became, alongside the companion Leisure Satisfaction Scale, the most widely used motivation measure in leisure studies and tourism.
