TL;DR: The clinimetric and clinical properties of the PSQI suggest its utility both in psychiatric clinical practice and research activities.
Abstract: Despite the prevalence of sleep complaints among psychiatric patients, few questionnaires have been specifically designed to measure sleep quality in clinical populations. The Pittsburgh Sleep Quality Index (PSQI) is a self-rated questionnaire which assesses sleep quality and disturbances over a 1-month time interval. Nineteen individual items generate seven "component" scores: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction. The sum of scores for these seven components yields one global score. Clinical and clinimetric properties of the PSQI were assessed over an 18-month period with "good" sleepers (healthy subjects, n = 52) and "poor" sleepers (depressed patients, n = 54; sleep-disorder patients, n = 62). Acceptable measures of internal homogeneity, consistency (test-retest reliability), and validity were obtained. A global PSQI score greater than 5 yielded a diagnostic sensitivity of 89.6% and specificity of 86.5% (kappa = 0.75, p less than 0.001) in distinguishing good and poor sleepers. The clinimetric and clinical properties of the PSQI suggest its utility both in psychiatric clinical practice and research activities.

TL;DR: Behavioral and pharmacological approaches are effective for the short-term management of insomnia in late life; sleep improvements are better sustained over time with behavioral treatment.
Abstract: ContextInsomnia is a prevalent health complaint in older
adults. Behavioral and pharmacological treatments have their benefits
and limitations, but no placebo-controlled study has compared their
separate and combined effects for late-life insomnia.ObjectiveTo evaluate the clinical efficacy of behavioral and
pharmacological therapies, singly and combined, for late-life insomnia.Design and SettingRandomized, placebo-controlled clinical trial,
at a single academic medical center. Outpatient treatment lasted 8
weeks with follow-ups conducted at 3, 12, and 24 months.SubjectsSeventy-eight adults (50 women, 28 men; mean age, 65
years) with chronic and primary insomnia.InterventionsCognitive-behavior therapy (stimulus control, sleep
restriction, sleep hygiene, and cognitive therapy)
(n=18), pharmacotherapy (temazepam)
(n=20), or both (n=20) compared with
placebo (n=20).Main Outcome MeasuresTime awake after sleep onset and sleep
efficiency as measured by sleep diaries and polysomnography; clinical
ratings from subjects, significant others, and clinicians.ResultsThe 3 active treatments were more effective than placebo
at posttreatment assessment; there was a trend for the combined
approach to improve sleep more than either of its 2 single components
(shorter time awake after sleep onset by sleep diary and
polysomnography). For example, the percentage reductions of time awake
after sleep onset was highest for the combined condition (63.5%),
followed by cognitive-behavior therapy (55%), pharmacotherapy
(46.5%), and placebo (16.9%). Subjects treated with behavior therapy
sustained their clinical gains at follow-up, whereas those treated with
drug therapy alone did not. Long-term outcome of the combined
intervention was more variable. Behavioral treatment, singly or
combined, was rated by subjects, significant others, and clinicians as
more effective than drug therapy alone. Subjects were also more
satisfied with the behavioral approach.ConclusionsBehavioral and pharmacological approaches are
effective for the short-term management of insomnia in late life; sleep
improvements are better sustained over time with behavioral
treatment.

TL;DR: Sleep appears to have not only a short‐term, use‐dependent function; it also serves to enforce rest and fasting, thereby supporting the optimization of metabolic processes at the appropriate phase of the 24‐h cycle.
Abstract: In the last three decades the two-process model of sleep regulation has served as a major conceptual framework in sleep research. It has been applied widely in studies on fatigue and performance and to dissect individual differences in sleep regulation. The model posits that a homeostatic process (Process S) interacts with a process controlled by the circadian pacemaker (Process C), with time-courses derived from physiological and behavioural variables. The model simulates successfully the timing and intensity of sleep in diverse experimental protocols. Electrophysiological recordings from the suprachiasmatic nuclei (SCN) suggest that S and C interact continuously. Oscillators outside the SCN that are linked to energy metabolism are evident in SCN-lesioned arrhythmic animals subjected to restricted feeding or methamphetamine administration, as well as in human subjects during internal desynchronization. In intact animals these peripheral oscillators may dissociate from the central pacemaker rhythm. A sleep/fast and wake/feed phase segregate antagonistic anabolic and catabolic metabolic processes in peripheral tissues. A deficiency of Process S was proposed to account for both depressive sleep disturbances and the antidepressant effect of sleep deprivation. The model supported the development of novel non-pharmacological treatment paradigms in psychiatry, based on manipulating circadian phase, sleep and light exposure. In conclusion, the model remains conceptually useful for promoting the integration of sleep and circadian rhythm research. Sleep appears to have not only a short-term, use-dependent function; it also serves to enforce rest and fasting, thereby supporting the optimization of metabolic processes at the appropriate phase of the 24-h cycle.

TL;DR: Stimulus control and sleep restriction were the most effective single therapy procedures, whereas sleep hygiene education was not effective when used alone.
Abstract: OBJECTIVE Because of the role of psychological factors in insomnia, the shortcomings of hypnotic medications, and patients' greater acceptance of nonpharmacological treatments for insomnia, the authors conducted a meta-analysis to examine the efficacy and durability of psychological treatments for the clinical management of chronic insomnia. METHOD A total of 59 treatment outcome studies, involving 2,102 patients, were selected for review on the basis of the following criteria: 1) the primary target problem was sleep-onset, maintenance, or mixed insomnia, 2) the treatment was nonpharmacological, 3) the study used a group design, and 4) the outcome measures included sleep-onset latency, time awake after sleep onset, number of nighttime awakenings, or total sleep time. RESULTS Psychological interventions, averaging 5.0 hours of therapy time, produced reliable changes in two of the four sleep measures examined. The average effect sizes (i.e., z scores) were 0.88 for sleep latency and 0.65 for time awake after sleep onset. These results indicate that patients with insomnia were better off after treatment than 81% and 74% of untreated control subjects in terms of sleep induction and sleep maintenance, respectively. Stimulus control and sleep restriction were the most effective single therapy procedures, whereas sleep hygiene education was not effective when used alone. Clinical improvements seen at treatment completion were well maintained at follow-ups averaging 6 months in duration. CONCLUSIONS The findings indicate that nonpharmacological interventions produce reliable and durable changes in the sleep patterns of patients with chronic insomnia.

TL;DR: These practice parameters provide recommendations regarding behavioral and psychological treatment approaches, which are often effective in primary and secondary insomnia, which replace or modify those published in the 1999 practice parameter paper produced by the American Sleep Disorders Association.
Abstract: Insomnia is highly prevalent, has associated daytime consequences which impair job performance and quality of life, and is associated with increased risk of comorbidities including depression. These practice parameters provide recommendations regarding behavioral and psychological treatment approaches, which are often effective in primary and secondary insomnia. These recommendations replace or modify those published in the 1999 practice parameter paper produced by the American Sleep Disorders Association. A Task Force of content experts was appointed by the American Academy of Sleep Medicine to perform a comprehensive review of the scientific literature since 1999 and to grade the evidence regarding non-pharmacological treatments of insomnia. Recommendations were developed based on this review using evidence-based methods. These recommendations were developed by the Standards of Practice Committee and reviewed and approved by the Board of Directors of the American Academy of Sleep Medicine. Psychological and behavioral interventions are effective in the treatment of both chronic primary insomnia (Standard) and secondary insomnia (Guideline). Stimulus control therapy, relaxation training, and cognitive behavior therapy are individually effective therapies in the treatment of chronic insomnia (Standard) and sleep restriction therapy, multicomponent therapy (without cognitive therapy), biofeedback and paradoxical intention are individually effective therapies in the treatment of chronic insomnia (Guideline). There was insufficient evidence to recommend sleep hygiene education, imagery training and cognitive therapy as single therapies or when added to other specific approaches. Psychological and behavioral interventions are effective in the treatment of insomnia in older adults and in the treatment of insomnia among chronic hypnotic users (Standard).
