- The link between technology and sleep is more complex than originally thought. In this updated theoretical review, we propose a new model informed by the growing body of evidence in the area over the past 10 years. The main theoretical change is the addition of bi-directional links between the use of technology and sleep problems. We begin by reviewing the evidence to date for the originally proposed mechanisms of bright light, arousal, nighttime sleep disruptions, and sleep displacement. Then, in support of the new direction of effect (sleep problems preceding technology use), we propose two new mechanisms: technology before sleep might be used as a time filler and/or as an emotional regulation strategy to facilitate the sleep-onset process. Finally, we present potential moderators of the association between technology and sleep, in recognition of protective and vulnerability factors that may mitigate or exacerbate the effects of technology on sleep and vice versa. The goal of this theoretical review is to update the field, guide future public health messages, and to prompt new research into how much technology and sleep affect each other, for whom it may be problematic, and which mechanisms may explain their association.

- The COVID-19 pandemic has seen a rise in anxiety and depression among adolescents. This study aimed to investigate the longitudinal associations between sleep and mental health among a large sample of Australian adolescents and examine whether healthy sleep patterns were protective of mental health in the context of the COVID-19 pandemic. We used three waves of longitudinal control group data from the Health4Life cluster-randomized trial (N= 2781, baseline Mage= 12.6, SD= 0.51; 47% boys and 1.4% ‘prefer not to say’). Latent class growth analyses across the 2 years period identifed four trajectories of depressive symptoms: low-stable (64.3%), average-increasing (19.2%), high-decreasing (7.1%), moderate-increasing (9.4%), and three anxiety symptom trajectories: lowstable (74.8%), average-increasing (11.6%), high-decreasing (13.6%). We compared the trajectories on sociodemographic and sleep characteristics. Adolescents in low-risk trajectories were more likely to be boys and to report shorter sleep latency and wake after sleep onset, longer sleep duration, less sleepiness, and earlier chronotype. Where mental health improved or worsened, sleep patterns changed in the same direction. The subgroups analyses uncovered two important fndings: (1) the majority of adolescents in the sample maintained good mental health and sleep habits (low-stabletrajectories), (2) adolescents with worsening mental health also reported worsening sleep patterns and vice versa in the improving mental health trajectories. These distinct patterns of sleep and mental health would not be seen using mean-centred statistical approaches.

- Growing evidence shows a link between mood and chronotype. The majority of studies measure chronotype as a preference for morning/evening activities, rather than actual sleep behavior (i.e., midsleep) or biological markers of sleep timing (e.g., dim light melatonin onset). Most studies show an association between chronotype and mood and identify eveningness as a potential risk for depression, but the directionality is unclear. Some evidence shows a stronger association between misalignment with the biological clock and depressive symptoms. This review provides a snapshot of recent research on chronotype and unipolar depression. We conclude that future studies should strive to integrate different measures of chronotype. This will give a clearer picture of the association between early/late chronotype and mood, which will in turn better inform clinical practice.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: During adolescence, peers gain a central role and with the availability of technology, socializing can occur around the clock. Very few studies have focused on the role of peers in adolescents’ sleep using social network analyses. These analyses describe peer relationships and social positions in a defined context (e.g., school) based on friendship nominations. Adolescents who receive many nominations can be defined as “popular”, which has been found to have its costs (i.e., shorter sleep duration) but also benefits (i.e., fewer insomnia symptoms). The aim of this study was to partially replicate and expand previous findings in a large Swedish sample of adolescents.Method: The sample included 1394 adolescents (46% girls, Mage = 15.3, SD = .53, range 14-18) from 16 public schools in middle Sweden. Adolescents reported on their weekly sleep duration, insomnia symptoms, anxiety, depression, alcohol use, demographics, and nominated up to three friends in school. We used R to calculate outgoing nominations and incoming nominations. Linear regressions were used to examine the association between popularity and sleep, controlling for confounding variables (demographics, emotional problems). Finally, we explored sex differences.Results: Controlling for confounders, popular adolescents reported shorter sleep duration (B=-3.00; 95% CI [-5.77, -0.19]), and popular girls reported more insomnia symptoms (B = 0.36; 95% CI [.04,.68]). There were no significant associations found for boys. Discussion: Popularity was linked to shorter sleep duration (up to -27 minutes for the most popular teens). Moreover, girls may pay a price for their popularity by experiencing more insomnia symptoms. Sex differences and potential mechanisms should be further explored.

Tidskriftsartikel (refereegranskat)abstract
- Study Objectives: We examined how adolescents’ sleep patterns (i.e. insomnia symptoms and sleep duration) change from early- to mid-adolescence and whether adolescents follow different trajectories. Furthermore, we also examined the characteristics of adolescents within different trajectories, with a specific focus on the role of school-related stress.Methods: We used three longitudinal waves of questionnaire data collected annually from a sample of Swedish adolescents (n = 1294; Mage = 13.2 [range: 12–15 years], SD = .42; 46.8% girls). Using established measures, the students reported on their sleep duration, insomnia symptoms, and perceived school-stress (including stress of school performance, peer and teacher relations, attendance, and school-leisure conflict). We used latent class growth analysis (LCGA) to identify adolescents’ sleep trajectories, and the BCH method to describe the characteristics of the adolescents in each trajectory.Results: We found four trajectories for adolescents’ insomnia symptoms; (1) low insomnia (69%), (2) low-increasing (17%, ‘emerging risk-group’), (3) high-decreasing (9%), (4) high-increasing (5%; ‘risk-group’). For sleep duration, we found two trajectories; (1) ~8 h sufficient-decreasing (85%), (2) ~7 h insufficient- decreasing (15%; ‘risk-group’). Adolescents in risk-trajectories were more likely to be girls and consistently reported higher levels of school stress, particularly regarding school performance and attending school.ConclusionsSchool stress was prominent among adolescents suffering from persistent sleep problems, especially insomnia, and deserves further attention.

Technology use as a sleep-onset aid : Are adolescents using apps to distract themselves from negative thoughts?
- 2023

Tidskriftsartikel (refereegranskat)abstract
- Study Objectives: The aim of this study was to; 1) explore whether adolescents use technology as distraction from negative thoughts before sleep, 2) assess whether adolescents who perceive having a sleep problem use technology as distraction more compared to adolescents without sleep complaints, 3) collect qualitative information about which devices and apps adolescents use as a distraction.Methods: This study used a mixed-methods cross-sectional design, where 684 adolescents (M = 15.1, SD = 1.2, 46% female) answered both quantitative and qualitative questions about their sleep (perceived sleep problem, sleep onset time, and sleep onset latency) and technology use as distraction from negative thoughts.Results: The majority of adolescents answered ‘yes’ or ‘sometimes’ using technology as a distraction from negative thoughts (23.6% and 38.4%). Adolescents who answered ‘yes’ to using technology as distraction were more likely to report having a sleep problem, longer sleep onset latency and later sleep onset time, compared to adolescents who answered ‘no’. The most popular device to distract was the phone, because of its availability, and the most common apps used for distraction included YouTube, Snapchat, and music apps.Conclusions: This study shows that many adolescents use technology to distract themselves from negative thoughts, which may help them manage the sleep-onset process. Thus, distraction may be one mechanism explaining how sleep affects technology use, rather than vice versa.

Sleep’s role in the development and resolution of adolescent depression
- 2022

Ingår i: Nature Reviews Psychology. - : Nature Publishing Group. - 2731-0574.

Forskningsöversikt (refereegranskat)abstract
- Two adolescent mental health fields—sleep and depression—have been advancing largely in parallel until the past 4 years. Although sleep problems have been conceptualised as a symptom of adolescent depression, emerging evidence suggests that sleep difficulties arise before depression. In this Review, we describe how the combination of adolescent sleep biology and psychology uniquely predispose adolescents to develop depression. We describe multiple pathways and contributors, including a delayed circadian rhythm, restricted sleep duration, and greater opportunity for repetitive negative thinking while waiting for sleep. We match each contributor with evidence-based sleep interventions, including bright light therapy, exogenous melatonin, and cognitive-behaviour therapy techniques. Such treatments improve sleep and alleviate depression symptoms, highlighting the utility of sleep treatment for comorbid disorders experienced by adolescents.
