Psychological tests used in a dizziness outpatient department Study on utilization of DHI in combination with psychological tests by each of the disease groups

This study compared the scores on each scale of the Japanese version of the Dizziness Handicap Inventory (DHI) consisting of the three subscales, used conveniently at a dizziness outpatient department, and psychological tests, such as the new version of the State Trait Anxiety Inventory (STAI) and Self-Rating Depression Scale (SDS) by a disease group. The participants included 126 patients (38 men and 88 women; mean age=55.10 years, SD 15.66) who visited the dizziness outpatient department for the first time during January 2014 to December 2015 and were categorized into three disease groups: psychogenic, central, and peripheral vestibular disease. A retrospective cohort investigation method was employed.
