Time estimation in chronic insomnia sufferers.
OBJECTIVE
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.


METHODS
Between subjects design.


METHODS
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).


METHODS
N/A.


RESULTS
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.


CONCLUSIONS
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.
