Kröner‐Herwig 1995.

Methods	Randomised controlled trial. Randomisation by drawing code numbers from a basket with the total sample.
Participants	43 (of 52 initially recruited) patients (60.5% male, mean age 48 years) allocated to 4 groups Inclusion criteria were: (1) Duration of tinnitus more than 6 months (2) Impairment due to tinnitus > 4 on a 10‐point rating scale (3) Hearing ability adequate for communication purposes (4) No treatable organic or psychological pathology (5) No current psychotherapy (6) Completed medical examination (7) Willingness to participate in the assessment and at least 8 to 10 treatment sessions
Interventions	Four experimental groups: (1) Tinnitus Coping Training 1 (TCT1 = 7 patients) (2) Tinnitus Coping Training 2 (TCT2 = 8 patients) (3) Yoga training (9 patients) (4) A waiting list control (WLC = 19 patients) Each treatment group (TCT1, TCT2, yoga) consisted of 10 2‐hourly sessions; each group was conducted by a different qualified professional
Outcomes	The outcome measures included: (1) Audiological: Tinnitus Sensation Level (TSL), Tinnitus Masking Level (TML) (2) Self‐monitoring tinnitus diary: subjective loudness, tinnitus discomfort, sleep disturbance, interference with activity, control of tinnitus and hours per day of tinnitus ignored (3) Self‐report questionnaires: TQ, and well‐being variables: depression, mood and symptoms All assessments were completed at pre‐treatment, post‐treatment and 3 months follow up (the latter one except for audiological outcomes)
Notes	The number of patients that were lost was 9 (3 in TCT1, 2 in TCT2t, 1 in yoga and 3 in the WLC). Total drop‐out = 9/43 = 20.93%. There were no adverse effects reported.
