What are patients completing Cognitive Behavioral Insomnia Therapy telling us with their post-treatment Insomnia Severity Index scores?

Mapping out Canadian adolescent sleep patterns: A mixed-methods approach.

“…This suggests that students report less issues with insomnia symptoms at night but find sleep to be overall unrefreshing and functioning to be impaired during the day. Research suggests that scores on the ISI are particularly influenced by perceptions of fatigue Marway et al, 2023). Consequently, daytime impairment because of short-changed sleep or circadian misalignment may be a contributor to a general sleep disturbance captured in the ISI.…”

“…When examining specific factors in the ISI, it should be noted that reported scores on “Severity” (consisting of difficulties falling asleep, staying, asleep, and early awakenings) were lower than “Impact” and “Satisfaction.” This suggests that students report less issues with insomnia symptoms at night but find sleep to be overall unrefreshing and functioning to be impaired during the day. Research suggests that scores on the ISI are particularly influenced by perceptions of fatigue (Lau et al, 2024; Marway et al, 2023). Consequently, daytime impairment because of short-changed sleep or circadian misalignment may be a contributor to a general sleep disturbance captured in the ISI.…”

“…Whereas retrospective approaches may be helpful in capturing global impressions of sleep duration and quality, prospective measures, such as the Consensus Sleep Diary (Carney et al, 2012), may be better positioned to capture nuance and variability of sleep patterns and are less susceptible to recall bias (e.g., Talari & Goyal, 2020). This is not meant to say that either method is inherently more valid and without criticism; it is simply to note that each method may have its unique utility and biases (Marway et al, 2023).…”
