The vestibular analyzer has numerous afferent afferents with various organs and systems. Increasing its sensitivity causes dizziness, imbalance, nausea, etc. The load on the vestibular analyzer in persons with high sensitivity to it adversely affects the psychological state of the person. However, the level of neuroticism, well-being, activity and mood, anxiety in such people have not been studied.
Aim. To assess the relationship among neuroticism, well-being, activity, mood, anxiety and vestibular resistance.
Materials and methods. The survey was attended by 612 students aged 17–19 years. We used the questionnaire method to select individuals with high sensitivity of the vestibular analyzer. Neuroticism was determined using the questionnaire of Eisenck. The feeling, activity and mood were evaluated by the questionnaire before and after the vestibular loading. The level of personal and situational anxiety was determined by Spielberger's method. Personal anxiety was evaluated before, and situational after vestibular loading. The vestibular load was carried out by rotational test, using a Barani’s chair.
Research results. According to the results of the questionnaire, we found 114 adolescents with an increased sensitivity of the vestibular analyzer, who was 18.6 %. Adolescents with reduced vestibular resistance, high neuroticism was in 43.9 % of cases, the average was 36.9 %, and the low – 19.3 %. We did not observe persons with very high neuroticism. The mean of neuroticism in the control group was 11 points, and in the hypersensitivity group of the vestibular analyzer – 14.7 points.
The arithmetic mean scores of well-being, activity and mood before and after the rotation test differed in the groups with proper and reduced vestibular stability. We found a deterioration in well-being in people with reduced vestibular stability. Activity to load did not differ. We observed its change in the study groups after the rotation test, namely the decrease in the group with increased vestibular sensitivity, compared with the control group. Mood levels differed between the groups with proper and reduced vestibular stability, both at rest and after rotation. The level of personal and situational anxiety in the group with decreased vestibular stability was higher than in the group with high functional activity of the vestibular analyzer.
Comparing situational anxiety depending on vestibular stability and neuroticism, we observed higher scores in students with reduced vestibular stability and low, medium, and high levels of neuroticism than in the group with proper vestibular stability and corresponding neuroticism. Our research shows that neuroticism, anxiety and vestibular stability are interrelated. Since, in the vast majority of persons with vestibular dysfunction, certain peculiarities of the mental state are formed, therefore, the level of neuroticism and anxiety of the subjects should be taken into account when planning diagnostic and treatment.
Conclusions. Persons with reduced vestibular stability are associated with increased neuroticism. The feeling and mood are lower in adolescents with increased vestibular sensitivity. Vestibular loads significantly reduce the feeling of state of health, activity and mood in adolescents with reduced vestibular stability. Students with reduced vestibular resistance have high personal and situational anxiety.
