The Pittsburgh sleep quality index: A new instrument for psychiatric practice and research
The clinimetric and clinical properties of the PSQI suggest its utility both in psychiatric clinical practice and research activities. Expand

A paper product intended for use as an advertising piece or the like and capable of being made from a single web of material by a web fed machine consists of a multiple paged brochure, a returnExpand
The Pittsburgh Sleep Diary
The Pittsburgh Sleep Diary is an instrument with separate components to be completed at bedtime and waketime that was shown to have sensitivity in detecting differences due to weekends, age, gender, personality and circadian type, and validity in agreeing with actigraphic estimates of sleep timing and quality.

Quantification of subjective sleep quality in healthy elderly men and women using the Pittsburgh Sleep Quality Index (PSQI)
Results show that subjective sleep quality does deteriorate in the healthy elderly, but not to the level seen in patients with sleep disorders, and Extremely healthy elderly subjects appear to adapt in their perception of objectively disturbed sleep. Expand
An attachment-based model of complicated grief including the role of avoidance
An avoidance questionnaire is developed to characterize avoidance among patients with CG as a stress response syndrome that results from failure to integrate information about death of an attachment figure into an effectively functioning secure base schema and/or to effectively re-engage the exploratory system in a world without the deceased.

Self-reported sleep quality predicts poor cognitive performance in healthy older adults.
Sleep problems may contribute to performance variability between elderly individuals but only in certain cognitive domains, and poor sleep was associated with increased depressive symptomatology but only for functional symptoms. Expand
Association study of eight circadian genes with bipolar I disorder, schizoaffective disorder and schizophrenia
Evidence for association between specific SNPs at the circadian gene loci and BD1 is tentative, and additional studies using larger samples are required to evaluate the associations reported here. Expand
The Social Rhythm Metric An Instrument to Quantify the Daily Rhythms of Life
The Social Rhythm Metric is an instrument designed to quantify an individual's daily social rhythms and its potential for integrating psychosocial and biological research and its clinical applicability are discussed. Expand
Circadian rhythms in human performance and mood under constant conditions
Between‐task heterogeneity in circadian performance rhythms appeared to be absent when the sleep/wake cycle was suspended; temperature, cortisol and melatonin appeared equally good as circadian correlates of performance, and subjective alertness correlated with performance rhythms as well as (but not better than) body temperature, suggesting that performance rhythms were not directly mediated by rhythms in subjective Alertness.

Two-year outcomes for interpersonal and social rhythm therapy in individuals with bipolar I disorder.
Interpersonal and social rhythm therapy appears to add to the clinical armamentarium for the management of bipolar I disorder, particularly with respect to prophylaxis of new episodes. Expand
