ABSTRACT Problems in sleeping are widely prevalent in modern society and are often one of the presenting complaints of patients consulting physicians. In addition, there is scattered epidemiologic evidence and considerable clinical support that disturbed or inadequate sleep may be a risk factor for clinical emergence of cardiovascular disease and for total mortality. The role of sleep problems both as a precursor and as a sequela of disease states could be better delineated in large groups by the availability of a brief, reliable and standardized scale for sleep disturbance. Such a scale could also be used to evaluate the impact of different therapies upon sleep problems. This paper presents data from two study populations responding to three and four item self-report scales. From 9 to 12% of air traffic controllers reported various sleep problems to have occurred on half or more of the days during the prior month, whereas 12-22% of patients 6 months after cardiac surgery reported such frequent sleep problems. Utilizing data from the 6 and 12 month follow-ups, test-retest reliability of the three-item scale in cardiac surgery patients was found to be 0.59. Internal consistency coefficients for the three and four-item scales were 0.63 and 0.79 respectively.

    • "). The reliability and validity of these three questionnaires have been demonstrated in previous studies (Bastien et al., NORTH AMERICAN JOURNAL OF PSYCHOLOGY 2001; Douglass et al., 1994; Jenkins et al., 1988). The 7-item Insomnia Severity Index asks questions about insomnia in the last two weeks (Cronbach's α = .85). "

    ABSTRACT: This study examined whether sleep problems predicted academic performance, classroom disruptive behavior, and substance use among 171 adolescents (58% female; age: M =14.05, SD =1.46). We also tested whether poor self-regulation mediated such relationships. Students reported their sleep problems (i.e., insomnia), reasons for doing schoolwork, ability to control their attention and behavior, school grade, classroom disruptive behavior, and substance use. Teacher ratings of academic performance were also gathered. The results showed that self-regulation significantly mediated the effects of sleep problems on academic performance, classroom disruptive behavior, and substance use. The developmental implications of the findings were discussed. Sleep problems are a major public health issue in the U.S. An estimated 70 million Americans suffer from sleep problems and about 30 million Americans have frequent or chronic insomnia (National Institute of Health, 2006). According to a national study, more than one half (56%) of 6 th -12 th graders got less sleep than they thought they needed to feel their best; 51% felt tired or sleepy during the day and 51% had difficulty falling asleep at least once in the last two weeks (National Sleep Foundation, 2006). This study examined the relationship among sleep problems, academic performance, and substance use among a group of adolescents. The study also tested whether self-regulation mediated the effect of sleep problems on academic performance and substance use.

    ABSTRACT: Purpose – The purpose of this paper are twofold. First, the authors examined the effects of two types of working hard (i.e. work engagement, workaholism) on employees’ well-being (i.e. job satisfaction, perceived stress, and sleep problems). Second, the authors tested the extent to which both types of working hard mediate the relationship between three types of work-related social support (i.e. perceived organizational support, perceived supervisor support, and perceived coworker support) and employees’ well-being.

    • "Depressive symptomatology over the past two weeks was assessed using the Beck Depression Inventory (BDI-II; German Version: Hautzinger et al., 2009) and the ENRICHD Social Support Inventory (ESSI; German Version: Spaderna et al., 2009) was employed to measure general perceived social support. Finally, the Jenkins Sleep Problem Questionnaire (JSPQ, Jenkins et al., 1988) was used to assess self-reported sleep problems over the previous months. "

    ABSTRACT: Hair cortisol concentrations (HCC) are assumed to reflect integrated long-term cortisol levels and have been proposed as a promising endocrine marker of chronic psychological stress. The current study examined HCC in relation to caregiving burden, a well-established naturalistic model of chronic stress in humans. HCC and relevant psychosocial data were examined in 20 caregivers of relatives with dementia and 20 non-caregiver controls matched for age and sex. Results revealed elevated HCC in dementia caregivers compared to non-caregiver controls (F(1,38) = 4.4, p = .04, ηp2 = .10). Further, within caregivers, a trend for a positive association of HCC with self-reported caregiving burden (r = .43, p = .058) and a positive association with depressiveness (r = .48, p = .045) were observed. No other associations between HCC and subjective measures were seen. These findings concur with the notion that HCC sensitively capture endocrine aberrations in stress-exposed groups.
