Preoperative anxiety: detection and contributing factors.

Author information

Department of Anaesthesia, University Hospital, London, Ontario, Canada.


The purpose of this study was to determine whether there is a correlation between anxiety the night before surgery and that existing immediately preoperatively, whether anaesthetists can detect preoperative anxiety and to establish the presence of any factors that might assist in the determination of preoperative anxiety. Anxiety was measured objectively using the Spielberger State-Trait Anxiety Inventory (STAI), and the Multiple Affect Adjective Check List (MAACL). Anxiety was found to be higher in females and those not having had a previous anaesthetic, and to remain constant from the afternoon before surgery to the immediate preoperative period. Anaesthetists were found to be poor assessors of anxiety unless they specifically questioned their patients about this.
