Background: Psychological comorbidities are frequent in tinnitus patients and their diagnosis is important for both interventions as well as treatment success. The selection of suitable questionnaires is thus crucial. The present study aimed to investigate the ICD-10 Symptom Rating (ISR) questionnaire for the diagnosis of psychological comorbidities.
Methods: The current study investigated tinnitus burden and psychological comorbidities in a sample of n = 311 patients with chronic tinnitus. All participants completed an intensive 7‑day multimodal tinnitus-specific therapy. Tinnitus burden was measured using the German version of the Tinnitus Questionnaire (TQ). Psychological comorbidities were measured using the ISR (total score, depressive disorder, anxiety disorder, obsessive-compulsive disorder, somatoform disorder, and eating disorder), the Perceived Stress Questionnaire (PSQ; total score, tension, worries, joy, and demands), and the General Depression Scale (Allgemeine Depressionsskala, ADS).
Results: Psychological comorbidities were suffered by 65% of participants. Treatment response comprised improvements in TQ, ISR, PSQ, and ADS. At baseline, tinnitus burden correlated with the ISR total, ISR obsessive-compulsive disorder, and PSQ tension scores. Post-treatment, the now reduced tinnitus burden was also predicted by the ISR depressive and eating disorder scores.
Conclusion: The ISR is a useful tool for measuring psychological comorbidities in patients with chronic tinnitus as well as for assessing short-term treatment response. Therapeutic approaches for chronic tinnitus should also consider stress-related tension, depressive symptomatology, and coping strategies such as maladaptive eating behaviors.
