What is the Sport Motivation Scale?
The Sport Motivation Scale (SMS) is a crucial tool in sport psychology designed to assess various aspects of motivation in sports and exercise contexts. Initially developed based on self-determination theory, the SMS evaluates both intrinsic and extrinsic motivation among youth sports and adolescent athletes. The revised Sport Motivation Scale, often referred to as the SMS-II, offers an updated framework for understanding these motivations, particularly among youth athletes.
The Sport Motivation Scale II (SMS-II) was developed by Rocchi, Vallerand, Deci, and Ryan (2013). Its development was published in the Journal of Sport and Exercise Psychology in 2012, where it was presented as a revised version of the original Sport Motivation Scale, addressing its psychometric properties and aligning it more closely with Self-Determination Theory (SDT) principles
The SMS II examines how factors like intrinsic motivation—where athletes engage in sports for personal satisfaction—and extrinsic motivation—where participation is driven by external rewards—affect sports participation and performance.
According to sports science, practicing sports reflects perceptual and motor skills. The scale is widely used in sports sciences and exercise psychology to study human behavior, social psychology, basic psychological needs, human motivation, and integrated regulation.
