[Measuring of preoperative anxiety by three self-reporting scales: State Trait Anxiety Inventory, Symptoms CheckList 92 and visual analogue scale].

Introduction: Preoperative anxiety is a common phenomenon. It is therefore necessary to investigate whether quantitative self-reporting anxiety scales can be helpful in the anaesthetic clinic and research. The aim of this study was to compare the state trait anxiety inventory (STAI), symptoms checklist 92 (SCL 92), the subscales anxiety and phobic anxiety, and a visual analogue scale for anxiety (VAS).
