Measures the full self-determination theory (SDT) motivation continuum applied to academic contexts — from amotivation through three forms of extrinsic motivation to three forms of intrinsic motivation. The Relative Autonomy Index (RAI) captures overall autonomous vs. controlled motivation. Widely used in educational psychology and student wellbeing research.
Likert (1–7, does not correspond at all to corresponds exactly) in response to 'Why do you go to college/school?'
Freely available from Robert Vallerand. A Relative Autonomy Index (RAI) can be computed as a weighted composite summarising autonomous vs. controlled motivation. Higher RAI = more autonomous motivation, predicting better academic adjustment, wellbeing, and persistence.
