      abstract     = {The development of therapeutic interventions for chronic
                      tinnitus requires sensitive and clinically responsive tools
                      to measure treatment-induced changes in tinnitus loudness
                      and annoyance. In this study, the authors evaluated the
                      psychometric properties of patient-reported visual analog
                      scales (VAS) for measuring subjectively perceived tinnitus
                      loudness and annoyance.The authors analyzed data from a
                      single-blind, randomized, placebo-controlled study of
                      acoustic coordinated reset (CR) neuromodulation in patients
                      with chronic tinnitus (trial registration: 'Randomized
                      Evaluation of Sound Evoked Treatment of Tinnitus [RESET]
                      study'; ClinicalTrials.gov identifier: NCT00927121) to
                      assess the reliability, validity, and minimally clinically
                      identifiable difference (MCID) of the VAS loudness and VAS
                      annoyance. The VAS loudness and VAS annoyance were completed
                      at screening, at baseline, and at 5 visits during the 16
                      weeks of the clinical study. Data were analyzed with respect
                      to test-retest reliability, validity, and MCID.VAS loudness
                      and VAS annoyance showed good test-retest reliability of .8
                      and .79, respectively. In terms of convergent validity, VAS
                      loudness and VAS annoyance correlated well with the tinnitus
                      questionnaire at all clinical visits (max r = .67, p < .05).
                      MCID estimates clustered between 10 and 15 points.VAS
                      loudness and VAS annoyance are valid and effective
                      measurements for capturing reductions in tinnitus severity
                      in patients with chronic tinnitus.},
