The Visual Analogue Scale for Anxiety (VAS-A) seems to be effective, fast and manageable, but has not been fully validated yet. The aim of this study is to validate VAS-A comparing it to, Corah's Dental Anxiety Scale (CDAS) Spielberger's State Trait Anxiety Inventory (STAI) and Beck Depression Inventory (BDI). Methods: One hundred consecutive patients (38 males and 62 females, median age 49 years) submitted to oral surgery filled out the VAS-A, CDAS, STAI forms Y1 and Y2, and BDI at preoperative examination - enrico.facco@unipd.it.
Abstract
BACKGROUND: Anxiety is a relevant but still underscored perioperative problem. The Visual Analogue Scale for Anxiety (VAS-A) seems to be effective, fast and manageable, but has not been fully validated yet. The aim of this study is to validate VAS-A comparing it to, Corah's Dental Anxiety Scale (CDAS) Spielberger's State Trait Anxiety Inventory (STAI) and Beck Depression Inventory (BDI). METHODS: One hundred consecutive patients (38 males and 62 females, median age 49 years) submitted to oral surgery filled out the VAS-A, CDAS, STAI forms Y1 and Y2, and BDI at preoperative examination; the order of administration of tests was randomized. RESULTS: VAS-A score was significantly correlated to CDAS (P<0.0001), STAI-Y1 (P<0.0001), STAI-Y2 (P<0.002) but not to BDI (P=0.18). ROC curve analysis suggested VAS-A equal to 46 mm as threshold for anxiety when using STAI Y1 equal to 40 as reference cutoff. CONCLUSION: Our study confirms that VAS-A is a reliable indicator of preoperative anxiety and may detect patients with depressive symptoms also. Values of VAS-A around 50 mm are a reliable threshold for a clinically meaningful level of preoperative anxiety.
