Summary of engagement scale measures.

Engagement scale measures	Type	Aim
Self-Awareness Deficits Interview (SADI) scale (89)	An interviewer-rated, semi-structured interview	To obtain both qualitative and quantitative data on the status of self-awareness following TBI. The interview has three areas of questions: (1) self-awareness of deficits; (2) self-awareness of functional implications of deficits; and (3) ability to set realistic goals
Intrinsic Motivation Inventory (IMI) (93)	Short- or long-form questionnaire	To measure grounded on the Self-Determination Theory (SDT) used in assessing the subjective experiences of participants when developing an activity. Specifically, it evaluates interest and enjoyment in a task, along with several other factors
Patients Activation Measure (PAM) (23)	A valid, highly reliable, unidimensional, probabilistic Guttman-like scale	To reflect a developmental model of activation, by assessing four different stages in patients activation: (1) believing the patient role is important, (2) having the confidence and knowledge necessary to take action, (3) taking action to maintain and improve one's health, and (4) staying the course even under stress
Profile Of Mood States (POMS) questionnaire (94)	A long (65 items) or short (35 items) questionnaires that contain a series of descriptive words/statements that describe feelings people have. The subjects self-report on each of these areas using a 5-point Likert scale	To measure peoples' mood state
