The overlap between DSPS and other co-occurring conditions such as depression and insomnia may account for some of the functional impairment.
The Severe Depression and Anxiety and Insomnia factors accounted for the largest proportion of the variance for most of the groups.
Some studies have investigated insomnia without accounting for sleep duration or use of hypnotic medication, both factors themselves associated with increased mortality, closely linked to insomnia and therefore potential confounders.
Furthermore, while we did assess depression and insomnia, which accounted for some of the functional impact of DSPS in the present study, there may be other covariates not addressed in the current study that may explain parts of this association.
The conclusion by Johnson et al. [ 8] that insomnia does not account for a significant proportion of DSPS was supported by the current study, as most of the adolescents with insomnia did not have DSPS.
It exists primarily as a Web portal where viewers can explore video confessionals, drawings, and quotes depicting personal accounts of insomnia, collected from two thousand individuals from around the world over a six-month period.
Two focus groups captured first-person accounts of insomnia patients' experiences learning mindfulness techniques, applying their newly acquired meditation practices and knowledge to improve sleep, and describing personal benefits to sleep and other aspects of their lives.
The team now plans to see if other mutations in the adenosine pathway might account for insomnia or other sleep disorders, says Landolt. "It's a very encouraging advance," says Mehdi Tafti, a geneticist at the University of Lausanne, Switzerland.
Adjustment is then made for baseline psychiatric distress (model B) in order to see how much of the gender and social class patterning of insomnia symptoms can be accounted for by initial distress.
These manifestations of overarousal (i.e., agitation, insomnia, nightmares, and anger) may account for the association between cognitive anxiety sensitivity and suicidal ideation.
