Cognitive variables in tinnitus annoyance.

Two new questionnaires were devised to investigate dimensions of complaint about tinnitus. Following a factor analysis of data provided by a sample of tinnitus patients who were administered the first questionnaire, the second questionnaire was developed. This included questions concerning coping attitudes and beliefs about tinnitus. The results of the two analyses were similar and they indicated the presence of three main dimensions of complaint (emotional distress, auditory perceptual difficulties, and sleep disturbance). However several smaller factors suggested that complaint was more complex than originally predicted. The second questionnaire successfully discriminated complaining from non-complaining patients.
