Actigraphic assessment of sleep disturbances following traumatic brain injury.
The current study examined the use of actigraphy in measurement of sleep following traumatic brain injury (TBI). Twenty-one patients with TBI and self-reported sleep and/or fatigue problems and 21 non-injured controls were studied over seven days using actigraphy and sleep diary reports. ⋯ Actigraphy may prove useful to supplement self-report measures of sleep following TBI. More work is required to understand the accuracy of these measures in this population.

Catastrophizing and poor sleep quality in early adolescent females.
Catastrophizing about sleeplessness has been investigated in adults and children, but little is known about adolescents. This article aimed to (a) investigate whether early adolescent girls catastrophized about consequences of sleeplessness, (b) describe topics in catastrophizing sequences, (c) examine the association between sleep quality and catastrophizing, and (d) assess whether puberty moderated this association. ⋯ Sleep quality was associated with catastrophizing (β = 0.19, p = .042); however, puberty did not moderate this association (β = 0.15, p = .126). Findings highlight the importance of sleep-related cognitions in adolescent girls.

Comparative StudyGreater night-to-night variability in sleep discrepancy among older adults with a sleep complaint compared to noncomplaining older adults.
Research in younger adults suggests sleep discrepancy (objective/subjective measurement difference) is a consistent pattern that primarily occurs within individuals with insomnia. To examine whether older adults exhibit a similar pattern, this study compared night-to-night inconsistency in sleep discrepancy between older adults with and without sleep complaints. Older adults (N = 103; mean age = 72.81, SD = 7.12) wore an Actiwatch-L® (24 hr per day) and concurrently completed sleep diaries for 14 days. ⋯ Both groups exhibited sleep discrepancy, but complainers exhibited significantly more night-to-night variability. Sleep discrepancy was a variable behavior that was not limited to insomnia, but instead manifested by degree throughout our older sample. Greater attention to variability in sleep research and clinical practice is warranted.

Pittsburgh and Epworth sleep scale items: accuracy of ratings across different reporting periods.
This study examined the ecological validity of sleep experience reports across different lengths of reporting periods. The accuracy of item responses on the Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS) across 3-, 7-, and 28-day reporting periods was examined in relation to electronic daily item ratings. ⋯ However, within-subjects analyses indicated low levels of accuracy in recall of sleep items for specific days in the last week. Thus, for the purpose of between-subject comparisons, patients generally can provide accurate recall of sleep experiences; studies requiring finer-grained analysis across time and within-subjects require daily diary methodology.

Insomnia and depressive symptoms in late pregnancy: a population-based study.
A population-based questionnaire study of 2,816 women was conducted in week 32 of pregnancy to estimate the prevalence of and risk factors for insomnia and depressive symptoms. The Bergen Insomnia Scale (BIS) measured insomnia. The Edinburgh Postnatal Depression Scale (EPDS) measured depressive symptoms. ⋯ The prevalence of depressive symptoms (EPDS ≥ 10) was 14.6%. Depressive symptoms were strongly associated with insomnia during late pregnancy, especially with sleep durations <5 or >10 hours, sleep efficiency <75%, daytime impairment, and long sleep onset latency. Pelvic girdle pain and lower back pain was associated with insomnia, but not with depressive symptoms.
