Academic Motivation Scale
Also known as: AMS, Intrinsic Motivation Scale
The Academic Motivation Scale (AMS) is a 28-item self-report instrument developed by Vallerand et al. (1992) to assess the quality of students' academic motivation. It distinguishes between intrinsic motivation (motivation for knowledge, accomplishment, and stimulation), extrinsic motivation (external regulation, introjected regulation, and identified regulation), and amotivation, grounded in self-determination theory.
Key highlights
- Grounded in self-determination theory, a robust motivational framework
- Multidimensional design distinguishes intrinsic, extrinsic, and amotivation
- Strong psychometric properties: validated across cultures and education levels
- Practical utility for identifying students at risk of dropout

When to use it
The AMS is used with college and university students to diagnose motivation profiles, identify at-risk students, evaluate intervention effectiveness, and understand persistence in academic programs. It suits longitudinal studies, predictive studies of academic outcomes, and cross-cultural comparisons of motivation patterns.
Strengths & limitations
- Grounded in self-determination theory, a robust motivational framework
- Multidimensional design distinguishes intrinsic, extrinsic, and amotivation
- Strong psychometric properties: validated across cultures and education levels
- Practical utility for identifying students at risk of dropout
- Self-report bias: students may over-report intrinsic motivation due to social desirability
- Context-dependent: motivation varies by subject and may require domain-specific versions
- Limited in capturing situational or episodic fluctuations in motivation

Frequently asked
Why are there three types of extrinsic motivation?
Self-determination theory posits a continuum of extrinsic motivation from fully controlled (external regulation, 'do it or face punishment') to more autonomous (identified regulation, 'I value this goal'). This nuance explains why some externally motivated students still succeed; they have internalized the value of their goals.
How is amotivation different from low intrinsic motivation?
Amotivation reflects a complete lack of intention to engage—students do not see the connection between effort and outcomes. Low intrinsic motivation means a student is driven by extrinsic factors but still intends to engage. Amotivation is a stronger predictor of dropout.
Can the AMS predict academic performance?
Intrinsic and identified extrinsic motivation are moderate positive predictors of GPA and persistence, while amotivation is a negative predictor. However, motivation is one of many factors affecting grades; study habits, ability, and course difficulty also matter significantly.
