In the studies
of subjects with PSG-delineated psychophysiological-type insomnia
or sleep state misperception-type insomnia, mentioned previously,
the following Multiple Sleep Latency test data (averaged over
test episodes) pertains (Bonnet
and Arand, 1995; Bonnet
and Arand, 1997).

Question
3.4.1
| The
Multiple Sleep Latency Test data corroborate the hypothesis
that people who have insomnia of the psychophysiologic-type
(i.e. less minutes of PSG sleep) show increased daytime sleepiness. |
|
| True |
|
| False |
Question
3.4.2
| People
who have insomnia, whether of the psychophysiological-or sleep
state misperception-type, do not appear to be any more sleepy
in the daytime that those without insomnia. |
|
| True |
|
| False |
Question
3.4.3
| The
Multiple Sleep Latency Test may not be a sensitive and accurate
measure of excessive daytime sleepiness for people with chronic
insomnia. |
|
| True |
|
| False |
Question
3.4.4
| The
extent of excess arousal/activation could be overriding the
sleep loss-derived elevation in sleep drive in people with
psychophysiological-type insomnia. In fact, people with insomnia
might have a weak sleep drive. |
