“…In the current sample, Cronbach alphas were acceptable (ISI=.83; PSQI=.75). The FOSQ-10 [56], a brief version of the original 30-item FOSQ [57], was used to assess the impact of sleepiness on functioning in everyday activities (Cronbach alpha=.89). Possible scores ranged from 5 to 20, with higher scores indicating better functional status.…”

Background Sleep disturbance is a major health concern among US veterans who have served since 2001 in a combat theater in Iraq or Afghanistan. We report subjective and objective sleep results from a pilot trial assessing self-management–guided use of a mobile app ( CBT-i Coach , which is based on cognitive behavioral therapy for insomnia) as an intervention for insomnia in military veterans. Objective The primary aim of this study was to evaluate changes in subjective and objective sleep outcomes from pre to postintervention. Methods Subjective outcomes included the Insomnia Severity Index, the Pittsburgh Sleep Quality Inventory, and sleep-related functional status. A wearable sleep monitor (WatchPAT) measured objective sleep outcomes, including sleep efficiency, percent rapid eye movement (REM) during sleep, sleep time, and sleep apnea. A total of 38 participants were enrolled in the study, with 18 participants being withdrawn per the protocol because of moderate or severe sleep apnea and 9 others who dropped out or withdrew. Thus, 11 participants completed the full 6-week CBT-i Coach self-management intervention (ie, completers). Results Completer results indicated significant changes in subjective sleep measures, including reduced reports of insomnia ( Z =–2.68, P =.007) from pre (mean 16.63, SD 5.55) to postintervention (mean 12.82, SD 3.74), improved sleep quality ( Z =–2.37, P =.02) from pre (mean 12.82, SD 4.60) to postintervention (mean 10.73, SD 3.32), and sleep-related functioning ( Z =2.675, P =.007) from pre (mean 13.86, SD 3.69) to postintervention (mean 15.379, SD 2.94). Among the objective measures, unexpectedly, objective sleep time significantly decreased from pre to postintervention ( χ 2 2 =7.8, P =.02). There were no significant changes in percent REM sleep or sleep efficiency. Conclusions These findings suggest that the CBT-i Coach app can improve subjective sleep and that incorporating objective sleep measures into future, larger clinical trials or clinical practice may yield important information, particularly by detecting previously undetected sleep apnea.

“…Three items from the Functional Outcomes of Sleep Questionnaire, a validated self-report assessment of functional impairment due to sleep disturbance (26), assessed insomnia: trouble with initially falling asleep, nighttime awakenings with trouble falling back to sleep, and early-morning awakenings with trouble falling back to sleep. Participants' responses were based on sleep in the past month and ranged from 0, "NEVER" to 4, "ALMOST ALWAYS".…”

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

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 of depression and other potential confounds. To extend these findings, we tested whether depression or sleep duration moderated the association between insomnia symptoms and frequency of suicidal ideation. We further replicated these findings in parallel analyses using the combined data from the 2005-2006 and 2007-2008 cycles. Results: This study replicated previous results showing that insomnia symptoms are associated with frequency of suicidal ideation in the NHANES 2005-2006 cycle (OR = 1.09, p < 0.05), even after adjusting for potentially confounding variables, including depression. Neither depression nor sleep duration moderated this association. Difficulty with sleep maintenance insomnia symptoms were most robustly associated with frequency of suicidal ideation (OR ≥ 1.97, p < 0.05). Sleep duration was not robustly associated with suicidal ideation. Conclusions: In this study, we found that insomnia symptoms were uniquely associated with frequency of suicidal ideation. This association cannot be explained by the shared association with depression or sleep duration.

Development of a Daily Use Caregiver Sleep Survey (DUCSS)

et al. 2020

Abstract. Dementia caregiving is associated with depression, stress, and sleep disturbance. A daily use caregiver sleep survey (DUCSS) was developed to evaluate caregiver sleep. The tool was distributed to 24 informal caregivers and validated using the Rasch model, which indicated that the 17-item survey produced sleep quality measures of sufficient reliability for both group-level and individual-level comparisons (reliability = .87). The sample size was sufficient to provide precise measures of the item’s position along the scale (item difficulty) (reliability = .85), so outcomes associated with sleep quality levels could be evaluated. We observed that the structure of the instrument is unidimensional, meaning the wording does not contain systematic biases peripheral to sleep quality. DUCSS is a useful tool for caregiver assessment and monitoring.
