Metrics & Methods: Questionnaires

Research on Self-Determination Theory has included laboratory experiments and field studies in several different settings. In order to do this research, we have developed many questionnaires to assess different constructs contained within the theory. Each questionnaire page will typically include:

  • the scale
  • description of the scale
  • a key for the scale, and
  • references for articles describing studies that used the scale
