Insomnia Is Associated With Frequency Of Suicidal Ideation Independent Of Depression: A Replication And Extension Of Findings From The National Health And Nutrition Examination Survey, Zach Simmons, Lance D. Erickson, Dawson Hedges, Daniel Kay

Faculty Publications

Objective: Insomnia is associated with suicidality, although the mechanisms of this association are unclear. This study sought to replicate previous findings showing that insomnia symptoms but not sleep duration are associated with frequency of suicidal ideation in adults. We further investigated whether depression or sleep duration moderates the association between insomnia symptoms and frequency of suicidal ideation.

Materials and Methods: We used the 2005–2006 cycle of the National Health and Nutrition Examination Survey to replicate previously reported findings from the 2007–2008 cycle. We used ordered logistic regression to determine whether insomnia symptoms were associated with frequency of suicidal ideation independently …

Let It Rest: Sleep And Health As Positive Correlates Of Forgiveness Of Others And Self-Forgiveness, Loren Toussaint, Andrew J. Gall, Alyssa Cheadle, David R. Williams

Faculty Publications

Objective: The present study examined forgiveness of others, self-forgiveness, sleep, and health in a nationally representative sample of United States adults. It was hypothesised that sleep would mediate the associations of forgiveness of others and self-forgiveness with health.

Design: A nationally representative survey of 1,423 United States adults.

Main Outcome Measures: Measures included forgiveness of others, self-forgiveness, sleep quantity, sleep quality, psychological distress, life satisfaction, and self-rated physical health.

Results: Forgiveness of others (β = .20, p < .001) and self-forgiveness (β = .11, p < .01) were associated with sleep and forgiveness of others (β = .24, p < .001) and self-forgiveness (β = .27, p < .001) were associated with health. Sleep was associated with health (β = .45, p < .001) and also acted as a mediator of the associations of forgiveness of others (β = .09, p < .01) and self-forgiveness (β = .05, p < .01) with health.

Conclusions: Forgiveness of others and self-forgiveness may attenuate emotions such as anger, regret, and rumination and provide …

Does Improving Marital Quality Improve Sleep? Results From A Marital Therapy Trial, Scott R. Braithwaite, Wendy M. Troxel, Jonathan G. Sandberg, Julianne Holt-Lunstad

Faculty Publications

For most adults, sleep is a dyadic behavior. Only recently have studies explored the dynamic association between sleep and relationship functioning among bedpartners. The current study is the first to examine bidirectional associations between changes in insomnia and changes in marital quality over time, in the context of a marital therapy trial. Among husbands, improvements in marital satisfaction were associated with a 36% decreased risk of insomnia at follow-up. Regarding the reverse direction, counter-intuitively, wife baseline insomnia was associated with improvements in husbands’ marital satisfaction, but only among the non-treatment seeking comparison group. Results are discussed in terms of implications …

The Contribution Of The Pineal Gland On Daily Rhythms And Masking In Diurnal Grass Rats, Arvicanthis Niloticus, Dorela D. Shuboni, Amna A. Agha, Thomas K. H. Groves, Andrew J. Gall

Faculty Publications

Melatonin is a hormone rhythmically secreted at night by the pineal gland in vertebrates. In diurnal mammals, melatonin is present during the inactive phase of the rest/activity cycle, and in primates it directly facilitates sleep and decreases body temperature. However, the role of the pineal gland for the promotion of sleep at night has not yet been studied in non-primate diurnal mammalian species. Here, the authors directly examined the hypothesis that the pineal gland contributes to diurnality in Nile grass rats by decreasing activity and increasing sleep at night, and that this could occur via effects on circadian mechanisms or …

Sleep In The Context Of Healthy Aging And Psychiatric Syndromes, Daniel Kay, Joseph M. Dzierzewski

Faculty Publications

Humans spend approximately 1/3 of their lives asleep. Whether due to evolutionary or ontogenetic factors, sleep and psychiatric disorders change with age. While much of sleep remains an enigma, the field of sleep research is experiencing an exponential increase in its understanding of the causes, correlates, and consequences of sleep disturbances. Although the relationship between age-related sleep and psychiatric conditions is a common clinical observation, empirical investigations into these associations remain scarce. Thus, treating patients with symptoms of sleep disorders in the context of psychiatric conditions remains a major challenge. This chapter reviews the state-of-the-science of sleep disorders in the …

The Cortisol Awakening Response (Car) In 2-To 4-Year-Old Children: Effects Of Acute Nighttime Sleep Restriction, Wake Time, And Daytime Napping, Colleen E. Gribbin, Sarah Enos Watamura, Alyssa Cairns, John R. Harsh, Monique K. Lebourgeois

Faculty Publications

The cortisol awakening response (CAR) is presumed critically important for healthy adaptation. The current literature, however, is hampered by systematic measurement difficulties relative to awakening, especially with young children. While reports suggest the CAR is smaller in children than adults, well-controlled research in early childhood is scarce. We examined whether robust CARs exist in 2- to 4-year-old children and if sleep restriction, wake timing, and napping influence the CAR (n?=?7). During a 25-day in-home protocol, researchers collected four salivary cortisol samples (0, 15, 30, 45?min post-wake) following five polysomnographic sleep recordings on nonconsecutive days after 4?hr (morning nap), 7?hr (afternoon …

Tackling Sleeplessness: Psychological Treatment Options For Insomnia In Older Adults, Joseph C. Dzierzewski, Erin M. O’Brien, Daniel Kay, Christina S. Mccrae

Faculty Publications

This paper provides a broad review of the extant literature involving the treatment of sleeplessness in older adults with insomnia. First, background information (including information regarding key issues in late-life insomnia and epidemiology of late-life insomnia) pertinent to achieving a general understanding of insomnia in the elderly is presented. Next, theories of insomnia in older adults are examined and discussed in relation to treatment of insomnia in late-life. With a general knowledge base provided, empirical evidence for both pharmacological (briefly) and psychological treatment options for insomnia in late-life are summarized. Recent advances in the psychological treatment of insomnia are provided …

Treatment Of Late-Life Insomnia, Christina S. Mccrae Phd, Joseph M. Dzierzewski Ms, Daniel Kay

Faculty Publications

Insomnia, defined as difficulty initiating and/or maintaining sleep at least 3 nights/week that is accompanied by complaints of sleep-related daytime impairment 1, 2, is the most common sleep disturbance in later life. Although insomnia can occur as an acute disorder (7 days or less), older adults are often afflicted with chronic insomnia (12 months or more3 ). Additionally, insomnia in older individuals is most frequently co-morbid in nature, occurring in the context of age-related medical/psychiatric conditions, increased medication usage, and/or polypharmacy. This chapter will focus on the conceptualization, assessment and treatment of late-life insomnia from a behavioral sleep medicine perspective. …

Tnfα Sirna Reduces Brain Tnf And Eeg Delta Wave Activity In Rats, Ping Taishi, Lynn Churchill, Mingxiang Wang, Daniel Kay, Christopher J. Davis, Xin Guan, Alok De, Tadanobu Yasuda, Fan Liao, James M. Krueger

Faculty Publications

Tumor necrosis factor alpha (TNFα) is a pleiotropic cytokine with several CNS physiological and pathophysiological actions including sleep, memory, thermal and appetite regulation. Short interfering RNAs (siRNA) targeting TNFα were incubated with cortical cell cultures and microinjected into the primary somatosensory cortex (SSctx) of rats. The TNFα siRNA treatment specifically reduced TNFα mRNA by 45% in vitro without affecting interleukin-6 or gluR1-4 mRNA levels. In vivo the TNFα siRNAα reduced TNFα mRNA, interleukin-6 mRNA and gluR1 mRNA levels compared to treatment with a scrambled control siRNA. After in vivo microinjection, the density of TNFα-immunoreactive cells in layer V of the …
