In a retrospective study with 61 Patients with clinically diagnosed psychophysiological insomnia it was examined how often laboratory results either confirmed the initial clinical impression, refuted or failed to support it, or added new or unsuspected information. All Patients were evaluated by means of a sleep/wake log, a sleep habits questionnaire, structured psychiatric and clinical interviews and a minimum of two consecutive nights of polysomnography. We found rather no substantial change in diagnosis after polysomnography (1 case of 61 (= 1,6%) failed to support the initial diagnosis). But there was found a high percentage (49%) of new or unsuspected information that could not refute the initial diagnosis. 28% were diagnosed having sleep state misperception. The special examination of this subgroup found no difference in a lot of clinical anamnestic, sociodemographic or testpsychological variables compared to patients with confirmed psychophysiological insomnia.    «
