The updated literature review was undertaken by Gaskin Research and incorporates research published from May 2017 to April 2019. Searches of five electronic databases returned 707 papers, three of which met the selection criteria for this review. This review found that there continues to be significant clinical and scientific interest in developing and validating tools for assessing risk of adverse outcomes (e.g., aggression and suicide). Limited attention, however, has been paid to developing a tool to facilitate the recognition of mental state deterioration more broadly.
