Research summary
This study aims to evaluate the psychometric properties of the Brain Injury Screening Index (BISI), a self-report questionnaire to screen for the presence of Acquired Brain Injury (ABI). To be effective, self-report measures must be consistent over time (test-retest reliability), across different assessors (inter-rater reliability) and the results must overlap with other recognised indicators of what is being measured (gold-standard) which, in the case of the BISI, would be documented evidence that a person has suffered an acquired brain injury. To achieve this, during the initial health assessment, nurses will ask participants 11 questions that screen for possible presence of brain injury. The same questions will be repeated two weeks later by an external researcher. The researcher will also gain consent to inspect the medical records of each individual, and establish whether there is any evidence of acquired brain injury. The results of the study will demonstrate the test-retest and inter-rater reliability of the BISI and its clinical validity. In addition, analysis of how the scores obtained in the self-report questionnaire map on to medical records will enable the calculations of cut-off scores that can confidently be used in clinical practice.
