Measuring global and type-specific motivation states in self-determination theory: implications for the dimensionality debate and distinction between approach and avoidance motivation

Recent research has demonstrated that self-report measures of experienced autonomy and external control relate to attitudes, behavior, and well-being consistent with self-determination theory (SDT) predictions. These motivational states have traditionally been inferred from reason-based measures of the SDT motivation types; inferences that may not be accurate, particularly when there are multiple reasons for engaging in an activity. In this research, we investigated whether self-report measures of the psychological states associated with the specific SDT motivation types might similarly elimin
