めまい外来で用いる心理検査

―DHI を併用した疾患群別活用法についての検討―

抄録

　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.

　The participants generally had high scores in the DHI evaluating the level of disabilities in daily life caused by dizziness symptoms, indicating that they had moderate dizziness subject to possible drug therapy and/or rehabilitation. Interestingly, the results of the psychological tests (STAI and SDS) as well as the DHI subscales varied among the disease groups. Patients with psychogenic dizziness tended to have emotional and functional difficulties due to their dizziness symptoms and to be more susceptible to a state of anxiety. Peripheral dizziness patients had a state of anxiety in the normal range and depressive symptoms were mild, but there was a correlation with DHI.
