“…In turn, poor daily sleep efficiency was associated with poor sleep quality. Relatedly, our findings indicate that baseline fear of sleep was associated with poor sleep quality, which is consistent with cross‐sectional research among trauma‐exposed individuals (Pruiksma et al ., ). In sum, this set of findings is consistent with the idea that PTSD‐specific factors (i.e.…”

“…Specifically, the FOSI measures avoidance and dread of nightmares or re‐experiencing, fear of loss of vigilance and night‐time vigilant behaviours. Prior research has suggested the FOSI possesses excellent internal consistency as well as temporal stability (Pruiksma et al ., ). In the current study, the FOSI also demonstrated excellent internal consistency ( α = 0.94).…”

“…The FOSI is a 23-item selfreport questionnaire designed to assess fear of sleep related to PTSD (Pruiksma et al, 2014). Specifically, the FOSI measures avoidance and dread of nightmares or reexperiencing, fear of loss of vigilance and night-time vigilant behaviours.…”

“…Assessing daily levels of PTSD could inform us as to whether increased PTSD symptoms during the day lead to poorer sleep that night. Furthermore, those with PTSD may begin to fear sleep due to its association with nightmares (Pruiksma et al ., ), which could further disrupt sleep onset. We considered fear of sleep a PTSD‐related variable rather than an insomnia‐related one due to its specificity with PTSD‐related insomnia (i.e.…”

Despite the high levels of comorbidity between post-traumatic stress disorder (PTSD) and sleep disturbance, little research has examined the predictors of insomnia and nightmares in this population. The current study tested both PTSD-specific (i.e. PTSD symptoms, comorbid anxiety and depression, nightmares and fear of sleep) and insomnia-specific (i.e. dysfunctional beliefs about sleep, insomnia-related safety behaviours and daily stressors) predictors of sleep quality, efficiency and nightmares in a sample of 30 individuals with PTSD. Participants participated in ecological momentary assessment to determine how daily changes in PTSD- and insomnia-related factors lead to changes in sleep. Multi-level modelling analyses indicated that, after accounting for baseline PTSD symptom severity, PTSD-specific factors were associated with insomnia symptoms, but insomnia-specific factors were not. Only daytime PTSD symptoms and fear of sleep predicted nightmares. Both sleep- and PTSD-related factors play a role in maintaining insomnia among those with PTSD, while nightmares seem to be linked more closely with only PTSD-related factors.

“…Whereas the BRAIN-K being a modification of an adult version may benefit from additional psychometric evaluations beyond the current age range. Also, the FoSI, measuring fear, being based on the adult version assessing fear in a rural trauma-exposed sample (150) warrants further psychometric scrutiny. In contrast to others, the RLS (117) proposes a difference in scores between two time points 14 days apart to identify RLS-related symptoms.…”

Pediatric Sleep Tools: An Updated Literature Review

Since a thorough review in 2011 by Spruyt, into the integral pitfalls of pediatric questionnaires in sleep, sleep researchers worldwide have further evaluated many existing tools. This systematic review aims to comprehensively evaluate and summarize the tools currently in circulation and provide recommendations for potential evolving avenues of pediatric sleep interest. 144 "tool"-studies (70 tools) have been published aiming at investigating sleep in primarily 6-18 years old per parental report. Although 27 new tools were discovered, most of the studies translated or evaluated the psychometric properties of existing tools. Some form of normative values has been established in 18 studies. More than half of the tools queried general sleep problems. Extra efforts in tool development are still needed for tools that assess children outside the 6-to-12-year-old age range, as well as for tools examining sleep-related aspects beyond sleep problems/disorders. Especially assessing the validity of tools has been pursued vis-à-vis fulfillment of psychometric criteria. While the Spruyt et al. review provided a rigorous step-by-step guide into the development and validation of such tools, a pattern of steps continue to be overlooked. As these instruments are potentially valuable in assisting in the development of a clinical diagnosis into pediatric sleep pathologies, it is required that while they are primary subjective measures, they behave as objective measures. More tools for specific populations (e.g., in terms of ages, developmental disabilities, and sleep pathologies) are still needed.
