Abstract: Objective To the psychometric characteristics of patients bothered by anxiety disorder with the Chinese Version of the scale Whiteley Index (WI-CV). Methods Totally we enrolled 291 patients with somatoform disorders, major depressive disorder, generalized anxiety disorder, panic disorder, and obsessive-compulsive disorder diagnosed with ICD-10 from five hospitals in Beijing, and 190 normal people were enrolled as the control. They were assessed with WI-CV, Chinese Version of Illness Attitude Scale(IAS-CV), Beck Depression Inventory-Ⅱ(BDI-Ⅱ), and Beck Anxiety Inventory(BAI). Results The exploratory factor analysis resulted in 12 items and finally three factors, disease conviction, disease phobia, and bodily preoccupation. The total score of WI-CV was correlated with IAS-CV scores (r=0.69, P<0.01), BAI scores (r=0.50, P<0.01) and BDI-Ⅱ scores (r=0.38, P<0.01). Factor disease convince was correlated with IAS-CV scores (r=0.60, P<0.01), BAI scores (r=0.51, P<0.01) and BDI-Ⅱ scores (r=0.39, P<0.01). Factor disease phobia was correlated with IAS-CV scores (r=0.60, P<0.01), BAI scores (r=0.25, P<0.01) and BDI-Ⅱ scores (r=0.14, P>0.01).Factor bodily preoccupation was correlated with IAS-CV scores (r=0.49, P<0.01), BAI scores (r=0.41, P<0.01) and BDI-Ⅱ scores (r=0.37, P<0.0 1). Patients with somatoform disorders (7.24±2.89) had higher scores than patients with other disorder, such as depression (4.77±2.99), anxiety (5.07±3.05), obsessive compulsive disorder (5.91±2.73), and normal controls (2.52±2.58). Obsessive compulsive disorder had higher scores than other four disorders. Normal controls get the lowest score than other patients. The Cronbach's α coefficients were 0.82 for WI-CV total score and 0.53-0.71 for each subscale. Pearson coefficient measured between total score and factor score were 0.91, 0.76, and 0.76. Split-half coefficient of WI-CV was 0.83, and Split-half coefficient of subscales were 0.59-0.74. Conclusion It suggested that the WI-CV has good psychometric features and it may be trialed in clinical practice and research in China.
