The role of questioning environment, personality traits, depressive and anxiety symptoms in tinnitus severity perception.

Psychological factors have been described as important for tinnitus severity, but attempts to incorporate them in one picture are sparse. This study investigated to what extent traits (personality), states (depressive and anxiety symptoms), sociodemographic factors and questioning environment influence tinnitus severity perception and how they interplay. Data were obtained from 212 subjects in a survey that was undertaken in 2016 at Vilnius University hospital and via internet. Measures included the Tinnitus Handicap Inventory (THI), Visual Analogue Scale (VAS), Hospital Anxiety and Depression Scale (HADS), Big Five Personality Dimensions Scale and sociodemographic questions. A series of stepwise forward and multiple regression analyses were undertaken to discover how factors interconnect. Female gender, age, living in rural area, but not level of education, were found to be associated with THI and HADS. Total HADS score and of both subscales were linked to scores on THI, VAS scales and all personality traits, except agreeableness (and consciousness for anxiety). Anxiety was the most important predictor for tinnitus severity, followed by depressive symptoms. Only neuroticism from personality dimensions was a predictor of THI score, whereas THI scores did not predict scores on neuroticism. All results in scales were higher in the internet group, except agreeableness and neuroticism, while extroversion correlated negatively with THI score only in the hospital group. Tinnitus severity was highly correlated with depressive, anxiety symptoms and neuroticism. Respondents recruited through internet had higher scores on most parameters. Results emphasize the importance of psychological factors in tinnitus management.
