Assessing aggression following Acquired Brain Injury (ABI): a systematic review of assessment measures.

Objective: To conduct a systematic review to identify and examine the reliability and validity of standardized measures used to assess aggression in people with ABI. Data sources: Systematic searches of PsychInfo, Medline, Embase, PubMed and CINAHL databases along with hand searching of gray literature and review articles. Study selection: Studies were included if the sample had an ABI, and the measure included assessment of aggression. Data extraction: Sample and measure characteristics and psychometric properties were extracted. Measure quality was assessed using the COSMIN checklist. Data synthesis: Of 5,100 abstracts screened, 78 were reviewed in full against the inclusion and exclusion criteria, and 25 articles met the criteria for analysis. Included articles assessed the psychometric properties of 17 different measures of aggression in adults with ABI. Quality of evidence was often low. Four measures (MBPC-1990R, NFI, SASNOS and KSMS) demonstrated positive evidence of at least one psychometric property with good quality evidence. Conclusions: Although a large number of general measures were available, there are few measures that only assess post-ABI aggression, and many are not well-validated. Future research should assess the psychometric properties of these measures.
