MOTIVATION FOR TRAUMATIC BRAIN INJURY REHABILITATION QUESTIONNAIRE (MOT-Q) - RELIABILITY, FACTOR-ANALYSIS, AND RELATIONSHIP TO MMPI-2 VARIABLES

A Likert scale questionnaire was developed to assess motivation for po stacute rehabilitation by traumatic brain injury patients. Items were designed to reflect head-injured individuals' statements about their a ttitudes toward head injury rehabilitation. Factors such as denial of illness, anger, compliance with treatment, and medical information see king behavior were used to assess unfavorable and favorable components of motivation. Reliability was assessed using Cronbach's Alpha, which was found to be 0.91 for the total scale. Four factor analysis derive d subscales were identified: Lack of Denial, Interest in Rehabilitatio n, Lack of Anger, and Reliance on Professional Help. Correlation and m ultiple regression analyses demonstrated moderate relationships betwee n MOT-Q and several MMPI-2 variables largely related to indicators of somatic distress, depression and capacity for self-sufficiency. Lack o f Denial subscale showed the strongest relationship to MMPI-2 of all M OT-Q variables, while Interest in Rehabilitation showed the best corre lation to the MOT-Q total.
