Abstract:

<p><b>STUDY OBJECTIVE: </b>The objective of the present study is 2-fold: (1) compare the time-estimation performance of chronic insomnia sufferers to that of good sleepers and (2) evaluate the severity of the sleep complaint in order to assess its association with the time-estimation performance.</p><p><b>DESIGN: </b>Between subjects design.</p><p><b>PARTICIPANTS: </b>The sample included 11 individuals suffering from chronic primary insomnia (7 women and 4 men, mean age = 44.64 years, SD = 12.71) and 11 good sleepers (5 women and 6 men, mean age = 48.00 years, SD = 7.86).</p><p><b>INTERVENTIONS: </b>N/A.</p><p><b>MEASUREMENTS AND RESULTS: </b>All participants completed a time-estimation task, namely a finger-tapping task. The results indicate no significant between-group differences on time-estimation data, as well as no significant relationship between severity of insomnia complaint and estimation of time.</p><p><b>CONCLUSION: </b>These results suggest that the tendency to misestimate sleep difficulties is not linked to impaired time estimation-specific processes in insomnia sufferers, as measured with the present task.</p>
