Psychological complaints were investigated in two samples of 60 and 138 in-patients suffering from chronic tinnitus. We administered the Tinnitus Questionnaire (TQ), a 52-item self-rating scale which differentiates between dimensions of emotional and cognitive distress, intrusiveness, auditory perceptual difficulties, sleep disturbances and somatic complaints. The test-retest reliability was .94 for the TQ global score and between .86 and .93 for subscales. Three independent analyses were conducted to estimate the split-half reliability (internal consistency) which was only slightly lower than the test-retest values for scales with a relatively small number of items. Reliability was sufficient also on the level of single items. Low correlation between the TQ and the Hopkins Symptom Checklist (SCL-90-R) indicate a distinct quality of tinnitus-related and general psychological disturbances.
