Primary Outcome Measures
NameTimeMethod
Absolute Change in TBF-12 (Tinnitus Handicap Inventory-12) Total Score from Baseline.Baseline to week 17 and 29

The TBF-12 is an adapted German version of the original English THI (Tinnitus Handicap Inventory). It is a self-report questionnaire assessing 12 items from 2 dimensions: emotional-cognitive factors and functional-communicational factors. Each item is rated with 0-2 (2= "often"; 1= "sometimes"; 0= "never"). The maximum score is 24 indicating most severe tinnitus impairment.

Hierarchical test procedure: Step 1: week 29 in subjects reporting acute hearing loss; step 2: week 17, ditto; step 3: week 29 in total population; step 4: week 17, ditto.

Absolute Change in TSSw (Tinnitus Severity Scale - One Week Version) Total Score from Baseline.Baseline to week 17 and 29

The TSSw is a measure of tinnitus severity. It will be self-evaluated by the patient at various time points on an 11-point Likert-like scale asking for the past week. The scores range from 0 (indicating no tinnitus) to the maximum score of 10 (characterizing the most severe tinnitus considered).

Hierarchical test procedure: Step 1: week 29 in subjects reporting acute hearing loss; step 2: week 17, ditto; step 3: week 29 in total population; step 4: week 17, ditto.

Secondary Outcome Measures
NameTimeMethod
TBF-12 Total Score: Change from BaselineBaseline to week 5, 17, 23, and 29

See outcome measure #1.

TBF-12 Factorial Scores: Change from BaselineBaseline to week 5, 17, 23, and 29

See outcome measure #1.

TBF-12: Individual Responder RateWeek 5, 17, 23, and 29

See outcome measure #1. A subject is considered responder if TBF-12 decreases at least 4 score points between baseline and respective visit.

Tinnitus Rating Scale (one week version): Change from BaselineBaseline to week 5, 17, 23, and 29

Tinnitus Rating Scale is a self-evaluated 11-point Likert scale assessing tinnitus loudness, annoyance, and impact on life. The scores range from 0 (no impact), to the maximum score of 10 (worst influence of the problem considered). Single scores and sum scores will be analysed.

Tinnitus Severity Scale (one week version): Change from BaselineBaseline to week 5, 17, 23, and 29

See outcome measure #2.

Attention and Performance Self-Assessment (ASPA) Questionnaire: Change from BaselineBaseline to week 5, 17, 23, and 29

The ASPA consists of 30 simple statements for which the patient can determine how regular this happens to him/her. The response options for each statement are "never", "seldom", "sometimes", "often" and "always".

Quality of Life Questionnaire (SF-36™ Health Survey): Change from BaselineBaseline to week 17 and 29

The SF-36 is a multipurpose health survey with 36 questions. It is a generic measure commonly used in general and specific populations, comparing the relative burden of diseases, and in differentiating the health benefits produced by a wide range of different treatments.

Hospital Anxiety and Depression Scale (HADS): Change from BaselineBaseline to week 17 and 29

The HADS is a self-assessment scale with 14 items which has been developed for non psychiatrists to detect states of depression and anxiety in a hospital outpatient population. Every item is rated with a scale (3= very often indeed; 2= quite often; 1= not very often; 0= not at all). Lower total scores indicate "normal", higher total scores "abnormal".
