title: Evaluation and treatment of sleep complaints: patients' subjective responses.
abstract: BACKGROUND
  This study set out to evaluate whether patients' expectations affected their responses to treatment of a sleep disorder.
  
  
  METHODS
  Fifty consecutive patients attending a sleep clinic for the first time and who had different diagnoses of sleep disorders were included in this study. The patients completed a set of 6 questionnaires on 7 occasions as they progressed through the process of a sleep clinic referral, assessment and treatment. Self-report questionnaires were used to assess their sleepiness, fatigue and alertness. Predictor measures included mental health and individual items assessing expectation regarding the seriousness of the sleep problem. A battery of questions dealt with mental health issues, patients' expectation and their commitment to the sleep investigation and treatment process. Each patient's responses were examined over a period of 6 months.
  
  
  RESULTS
  Immediately following their interview with the sleep consultant, the patients' concern regarding their sleep problem was higher than the first measures obtained at baseline. Compared to prior to their first consultation with a sleep specialist, while on treatment they directed more attention to their sleep problem when problems associated with fatigue were reduced. Although there was a lessening in fatigue with treatment, subjectively rated sleepiness (Epworth Sleepiness Scale) did not vary over the study. Contact with a sleep center and the diagnosis and treatment of individual sleep problems also resulted in improved satisfaction with life.
  
  
  CONCLUSIONS
  Contact with and treatment at a sleep clinic was found to be beneficial. The fatigue levels were reduced and the patients had greater life satisfaction regardless of the diagnosis and treatment of their sleep disorder, although subjective sleepiness did not change. Patient expectations were not critical in determining the outcome of the sleep clinic assessment.
