“…These findings support recent work in Norwegian adolescents. 7 The association between DSPD screening outcome and daytime functional impairments may at least in part be attributed to sleep deficiency and the consequential daytime sleepiness. We observed associations between the screening outcome for DSPD and daytime sleepiness as well as the magnitude of self-assessed sleep deficit and daytime sleepiness.…”

“…2,3 Although exact prevalence is not known, estimates in the general population range from 0.13% 4 to 0.17%, 5 with an increased rate in adolescents. [6][7][8] DSPD is associated with delayed endogenous circadian (~24-hour) rhythms, such as rhythms of melatonin and core body temperature, [9][10][11] as well as the rhythm of sleep propensity. 12 Other potential mechanisms for DSPD have been described, including reduced homeostatic sleep pressure leading to increased evening alertness, altered sensitivity to the circadian phase-resetting effects of light, and heightened cognitive activity due to comorbid sleep initiation insomnia.…”

“…3,4 Additionally, between 1%-8% of adolescent's meet diagnostic criteria for delayed sleep phase disorder, with the majority reporting at least one symptom. 5,6 A number of factors combine to make sleep vulnerable to disturbance in adolescence. Adolescence is associated with a reduction in the accumulation of homeostatic sleep pressure during wakefulness, a lengthening of the intrinsic period of the endogenous circadian oscillator, and a delay in the release of melatonin in the evening.…”

Objectives:The aim of this study was to test whether a cognitive behavioral and mindfulness-based group sleep intervention would improve sleep and anxiety on school nights in a sample of at-risk adolescents. We also examined whether benefits to sleep and anxiety would be mediated by improvements in sleep hygiene awareness and presleep hyperarousal. Methods: Secondary analysis of a randomized controlled trial conducted with 123 adolescent participants (female = 60%; mean age = 14.48) who had high levels of sleep problems and anxiety symptoms. Participants were randomized into a sleep improvement intervention (n = 63) or active control "study skills" intervention (n = 60). Preintervention and postintervention, participants completed the Pittsburgh Sleep Quality Index (PSQI), Spence Children's Anxiety Scale (SCAS), Sleep Beliefs Scale (SBS), and Presleep Hyperarousal Scale (PSAS) and wore an actiwatch and completed a sleep diary for five school nights. Results: The sleep intervention condition was associated with significantly greater improvements in actigraphy-measured sleep onset latency (SOL obj ), sleep diary measured sleep efficiency (SE subj ), PSQI, SCAS, SBS, and PSAS, with medium to large effect sizes. Improvements in the PSQI and SCAS were specifically mediated by the measured improvements in the PSAS that resulted from the intervention. Improvements in SOL obj and SE subj were not specifically related to improvements in any of the putative treatment mechanisms. Conclusions:This study provides evidence that presleep arousal but not sleep hygiene awareness is important for adolescents' perceived sleep quality and could be a target for new treatments of adolescent sleep problems.

“…As a consequence, people who have DSPD often experience work and school related impairments [1]. DSPD is most common among adolescents and young adults and the prevalence is between 5% and 16% according to the International Classification of Sleep Disorders (ICSD-2), and in accordance with a recent review and a recent prevalence study [1][2][3]. DSPD has been shown to have high comorbidity with other conditions such as depression, anxiety and attention disorders [4,5].…”

Delayed sleep phase disorder (DSPD) is a disorder where the circadian rhythm is delayed according to the conventional norms, often resulting in school-and work related difficulties as well as emotional challenges. Research on the experiences of having DSPD is lacking, and to enhance our understanding we conducted a qualitative study using indepth semi structured interviews focusing on the challenges of having DSPD. A sample of 9 participants (16-23 years) diagnosed with DSPD was interviewed and analysis was done using systematic text condensation. A core theme in all interviews was how to cope with different challenges related to the disorder. We labelled the identified challenges: 1) To give something up; 2) To blame something or someone and 3) To have a problem or not. Awareness of these challenges adds to our understanding of the daily struggles of those with DSPD and may improve clinicians` competence and ability to help them.

Prevalence and correlates of delayed sleep phase in high school students

Abstract: Delayed sleep phase appears to be common amongst Norwegian adolescents and is associated with negative outcomes such as lower average school grades, smoking, alcohol usage, and elevated anxiety and depression scores.
