Disqualified and Qualified Poor Sleepers: Subjective and Objective Variables.

Abstract : Sleep laboratory studies of patients complaining of insomnia have demonstrated discrepancies between subjective reports and EEG-recorded measures. In our research studies on sleeping aids, 60% of the self-described poor sleepers who reported usual sleep latencies of at least 45 minutes did not meet the laboratory qualification criterion of a 30-minute or longer sleep latency. To better predict who would qualify for our studies, we compared 30 laboratory-qualified poor sleepers (QPSs) with 30 laboratory-disqualified.
