Some method of assessing self-awareness of deficits in patients with t
raumatic brain injury (TBI) is required to increase our understanding
of the phenomenon, and to then evaluate strategies for clinical interv
ention with patients who lack such self-awareness. Options for the ass
essment of self-awareness of deficits following TBI are reviewed. The
most commonly used method is comparison of patients' self-ratings on q
uestionnaires of functional abilities with ratings by relatives or sta
ff on the same questionnaires. An additional method of assessment, an
interviewer-rated semi-structured interview is proposed (the Self-Awar
eness of Deficits Interview), and some preliminary inter-rater reliabi
lity data are presented. However, quantitative methods of evaluating s
elf-awareness have shortcomings, and qualitative research may be more
appropriate in some circumstances. An approach which makes use of mult
iple measures to evaluate self-awareness of deficits is recommended.
