The effect of slow wave sleep deprivation on mood in adolescents with depressive symptoms: A pilot study

BackgroundThere is an urgent need for safe, rapid-acting treatment strategies for adolescent depression. In depressed adults, slow wave sleep deprivation (SWSD) improved next-day mood without disrupting sleep duration, but SWSD has not been tested in adolescents. In a pilot study, the aim was to assess the effect of SWSD on sleep physiology and mood outcomes (depression, rumination, anhedonia) among adolescents with depressive symptoms. MethodsSixteen adolescents (17.44 ± 1.46 yr, 12 female) completed three nights of polysomnographic sleep recording: Baseline, SWSD, and Recovery nights. Acoustic stimulation (tones of random pitch, duration, and volume) suppressed slow wave sleep (SWS) in real-time during SWSD. After each night, depression, rumination, and anhedonia severity were assessed. ResultsSWSD successfully suppressed SWS, increased N2, and had minimal impact on Rapid Eye Movement (REM), nocturnal awakenings, and total sleep time. While SWSD did not improve depression or anhedonia severity overall, lower baseline non-REM alpha activity and greater SWS rebound during recovery sleep correlated with SWSD-related reduction in clinician-rated depression severity. Next-day rumination severity decreased after SWSD, with sustained improvements following recovery sleep. However, rumination improvement was not associated with SWS suppression, but rather reduction in total sleep time and REM in exploratory correlation models. LimitationsSmall sample size and large proportion of females. ConclusionSWSD did not improve depression in adolescents overall but a subset with low non-REM alpha activity and intact homeostatic sleep regulation may benefit from this approach. Findings from this pilot study also suggest that partial sleep deprivation may be a beneficial therapeutic strategy for rumination in adolescents.

Adolescents’ daily social media use and mood during the COVID-19 lockdown period

Adolescents’ relationship to social media (SM) use shifted significantly during the COVID-19 lockdown. However, less is known about how adolescents’ social media use behaviors and mood were associated during this time. This study examined objective (passively sensed) SM use—including ‘screen time’ (duration of use) and checking (frequency of opening apps), retrospective daily reports of positive and negative affect during SM use, and general negative mood among adolescents during the COVID-19 lockdown period. Participants included 19 adolescents (Mean age = 15.8; 37 % female). Bayesian multilevel models examined whether within person-changes in SM ‘screen time’ and checking were associated with 1) retrospectively reported positive and negative affect while using SM and daily duration of SM use, 2) daily reports of overall negative mood. These relationships were examined both within the same day and prospectively (one day's SM behaviors predicting next-day mood and vise versa). On the same day, stronger positive or negative mood during SM use were associated with more SM ‘screen time’ (duration) and checking. Prospectively (next-day models), checking SM more frequently than usual was uniquely associated with within-person increases in adolescents’ positive mood when using SM the next day (p < .05), but not negative mood when using SM the next day. However, neither ‘screen time’ nor checking were associated with general negative mood on the same day or next day. These findings support the notion that SM is rewarding by highlighting that higher-than-usual SM checking is associated with within-person increases in positive mood during use. These findings also add to growing evidence that social media may not be directly tied to adolescents’ general mood state.

Capturing mood dynamics through adolescent smartphone social communication.

Most adolescents with depression remain undiagnosed and untreated-missed opportunities that are costly from both personal and public health perspectives. A promising approach to detecting adolescent depression in real-time and at a large scale is through their social communication on the smartphone (e.g., text messages, social media posts). Past research has shown that language from online social communication reliably indicates interindividual differences in depression. To move toward detecting the emergence of depression symptoms intraindividually, the present study tested whether sentiment (i.e., words connoting positive and negative affect) from smartphone social communication prospectively predicted daily mood fluctuations in 83 adolescents (Mage = 16.49, 73.5% female) with a wide range of depression severity. Participants completed daily mood ratings across a 90-day period, during which 354,278 messages were passively collected from social communication apps. Greater positive sentiment (i.e., more positive weighted composite valence score and a greater proportion of words expressing positive sentiment) predicted more positive next-day mood, controlling for previous-day mood. Moreover, greater proportions of positive and negative sentiment were, respectively, associated with lower anhedonia and greater dysphoria symptoms measured at baseline. Exploratory analyses of nonaffective linguistic features showed that greater use of social engagement words (e.g., friends and affiliation) and emojis (primarily consisting of hearts) predicted more positive changes in mood. Collectively, findings suggest that language from smartphone social communication can detect mood fluctuations in adolescents, laying the foundation for language-based tools to identify periods of heightened depression risk.

Daily trajectories of evening recovery experiences and their role for next-day mood.

Focusing on the definition of recovery as a process, we examined how the four core recovery experiences (i.e., psychological detachment, relaxation, control, and mastery) develop during the evening. We tested whether the specific developments of recovery experiences are important for next-day favorable mood states-beyond the mean levels of recovery experiences. We collected data from 92 employees who completed daily morning and afternoon surveys over 10 workdays. In the morning surveys, we implemented the day-reconstruction method to assess detailed information about employees' recovery experiences during several episodes of the previous evening. Our final data set included 477 morning surveys with a total of 1,998 episodes and 383 afternoon surveys. Multilevel growth curve analyses showed that, in general, psychological detachment, relaxation, and control follow a positive linear trend and mastery a negative quadratic trend during the evening. Moreover, path analyses showed that the day-level increase of psychological detachment is important for next-day mood. Specifically, we found that after evenings during which employees experienced a higher increase in psychological detachment than they usually did, they had higher favorable mood states in the subsequent afternoon. Further, our results did not support associations between day-level slopes of relaxation, control, and mastery as well as next-day mood. Hence, our study demonstrates that recovery experiences systematically change during an evening and that this change is partially relevant for next-afternoon mood.

Why so slangry (sleepy and angry)? Shorter sleep duration and lower sleep efficiency predict worse next-day mood in adolescents.

The goal of this study was to evaluate the relationships of actigraphic nighttime sleep duration and quality with next-day mood among urban adolescents using a micro-longitudinal design. A subsample (N = 525) of participants from the Fragile Families & Child Wellbeing Study (mean age: 15.4 years; 53% female; 42% Black non-Hispanic, 24% Hispanic/Latino, 19% White non-Hispanic) in the United States between 2014 and 2016 concurrently wore a wrist actigraphic sleep monitor and rated their daily mood in electronic diaries for about 1 week. Multilevel models tested the within-person temporal associations of nightly sleep duration and sleep maintenance efficiency with next-day reports of happiness, anger, and loneliness. The models also tested the between-person associations of sleep variables and mood. Models adjusted for sociodemographic and household characteristics, weekend, and school year. After nights when adolescents obtained longer sleep duration than their usual, they reported lower ratings of anger (B = -.03, p < .01) the next day. After nights when adolescents had higher sleep maintenance efficiency than their usual, they reported higher ratings of happiness (B = .02, p < .01) the next day. Adolescents who had longer average sleep duration reported lower ratings of anger (B = -.08, p < .01) and loneliness (B = -.08, p < .01) compared to others. There was no within-person association of sleep duration or efficiency with loneliness. Sleep duration was not associated with happiness between adolescents, and sleep maintenance efficiency was not associated with any mood measure between adolescents. Improvements to nightly sleep may help increase happiness and decrease anger the following day in adolescents. Promoting sleep health is recommended to improve mood.

Effects of alcohol on sleep and nocturnal heart rate: Relationships to intoxication and morning-after effects.

Alcohol consumption produces feelings of well-being and stimulation, but also impairs psychomotor performance, disturbs cardiovascular function and sleep, and can disrupt next-day mood and behavior. A deeper understanding of how the acute effects of alcohol relate to its sleep and morning-after effects is needed to minimize harm resulting from its use. This study examined relationships between the effects of a high dose of alcohol on subjective and psychomotor measures, nocturnal heart rate, sleep quality, and morning-after mood and behavior. We hypothesized that alcohol would produce disturbances in cardiovascular and sleep regulation during the night, which would predict morning-after mood and behavioral performance. Thirty-one men and women participated in two overnight laboratory visits during which they consumed either alcohol (1.0g/kg for men, 0.85 g/kg for women) or placebo (randomized, crossover design). They consumed the beverage from 8 to 9pm, and remained in the laboratory overnight for polysomnographic sleep recording. Subjective and behavioral measures were obtained during consumption and at 7-8am the morning after. Alcohol increased both negative and positive arousal, urge to drink and sedation, and it impaired performance on behavioral tasks. During sleep, alcohol produced expected tachycardia and detriments in sleep quality including decreased total sleep time, sleep efficiency, and altered sleep architecture. Only modest effects on mood or performance were detected the following morning. The acute sedative-like effects of alcohol were related to increases in N2 sleep, but not to other disruptions in sleep or nocturnal heart rate, and neither sleep impairments nor nocturnal heart rate were related to mood or task performance the morning after. The effects of alcohol on sleep and nocturnal heart rate were not strongly related to either its acute or morning-after effects. These findings do not provide strong support for the idea that alcohol-induced sleep disruptions underlie morning-after effects.

The Affective Consequences of Minority Stress Among Bisexual, Pansexual, and Queer (Bi+) Adults: A Daily Diary Study

Bisexual, pansexual, and queer (bi+) individuals are at increased risk for depression and anxiety. These disparities are hypothesized to be due to the unique, minority-specific stressors that they experience. Prior research supports that bi+ stressors are associated with depression and anxiety, but nearly all studies have been cross-sectional, limiting our understanding of how experiencing bi+ stress influences individuals’ levels of depression and anxiety as they occur in their day-to-day lives. To address this gap, we examined the daily associations between bi+ stressors (discrimination, internalized stigma, rejection sensitivity, and identity concealment) and depressed/anxious mood in a 28-day diary study. Participants were 208 bi+ individuals who completed daily measures of bi+ stressors and depressed/anxious mood. We tested unlagged (same-day) and lagged (next-day) associations, and we also tested whether internalized stigma, rejection sensitivity, and identity concealment functioned as mechanisms underlying the daily associations between discrimination and depressed/anxious mood. Participants reported higher depressed/anxious mood on days when they reported higher discrimination, internalized stigma, rejection sensitivity, and identity concealment. There were significant unlagged indirect effects of discrimination on depressed and anxious mood via internalized stigma and rejection sensitivity, and there was also a significant unlagged indirect effect of discrimination on anxiety via identity concealment. However, none of the lagged associations were significant. Results suggest that bi+ stress is related to same-day, but not next-day, depressed/anxious mood. The nonsignificant lagged associations could reflect that bi+ individuals are using adaptive coping skills in response to bi+ stress, or that other experiences throughout the day have stronger influences on next-day mood.

Impulsivity and sleep and circadian rhythm disturbance predict next-day mood symptoms in a sample at high risk for or with recent-onset bipolar spectrum disorder: An ecological momentary assessment study

Background: Impulsivity and sleep and circadian rhythm disturbance are core features of bipolar spectrum disorders (BSDs) that are antecedents to onset and persist even between mood episodes; their pervasive presence in BSD suggests that they may be particularly relevant to understanding BSD onset and course. Considerable research demonstrates bidirectional associations between impulsivity and sleep disturbance in healthy individuals; thus, it is important to examine how these features interact to impact BSD symptomatology.Methods: Young adults (N = 107, 55% female, M age = 21.82 years) at high risk for developing BSD (based on high self-reported reward sensitivity) or with recent-onset BSD participated in ecological momentary assessment (EMA) to examine relationships between impulsivity, sleep and circadian rhythm alterations, and mood symptoms in everyday life. Impulsivity was measured via self-report/behavioral task, sleep was measured via actigraphy, circadian rhythms were measured via dim light melatonin onset (DLMO) time, and mood symptoms were measured three times daily via self-report.Results: Multi-level modeling revealed that less total sleep time predicted increased next-day mood symptoms. Moreover, DLMO, total sleep time, and sleep onset latency moderated the relationship between impulsivity and EMA-assessed mood symptoms. Fewer minutes of sleep and later DLMO strengthened the positive relationship between impulsivity and mood symptoms.Limitations: Mood symptoms in our sample were mild; future studies should replicate findings in populations with more severe mood symptoms.Conclusions: This multi-method assessment of dynamic relationships revealed novel associations between impulsivity, sleep and circadian rhythm disturbance, and symptoms within individuals at high-risk for or with recent-onset BSD.

Use of digital health technologies to examine subjective and objective sleep with next-day cognition and daily indicators of health in persons with and without HIV

Most previous studies investigating sleep’s association with health outcomes have relied on averaged sleep quality and laboratory-based health measures. This study examines the dynamic within-person relationships between subjective (Ecological Momentary Assessment) and objective sleep (actigraphy) on next-day cognition (subjective and objective), mood, and engagement in daily activities using linear mixed-effects regression modeling. Participants included 94 individuals (59 people with HIV, 35 HIV-) aged 50–74, assessed daily for 14 consecutive days/nights. Subjective and objective sleep were well correlated and were both associated with subjective ratings of cognition, but not objective cognition. Worse subjective sleep was associated with next-day lower happiness and higher depressed mood, and more pain, but was not related to next-day daily activities. Objective sleep was associated with next-day depressed mood and feelings of worry, and was positively associated with next-day television watching. Results provide evidence to support the utility of real-time assessment for sleep and functional outcomes that may lead to potential personalized interventions for individuals with and without HIV.

Day-to-day variability in sleep parameters and depression risk: a prospective cohort study of training physicians

While 24-h total sleep time (TST) is established as a critical driver of major depression, the relationships between sleep timing and regularity and mental health remain poorly characterized because most studies have relied on either self-report assessments or traditional objective sleep measurements restricted to cross-sectional time frames and small cohorts. To address this gap, we assessed sleep with a wearable device, daily mood with a smartphone application and depression through the 9-item Patient Health Questionnaire (PHQ-9) over the demanding first year of physician training (internship). In 2115 interns, reduced TST (b = −0.11, p < 0.001), later bedtime (b = 0.068, p = 0.015), along with increased variability in TST (b = 0.4, p = 0.0012) and in wake time (b = 0.081, p = 0.005) were associated with more depressive symptoms. Overall, the aggregated impact of sleep variability parameters and of mean sleep parameters on PHQ-9 were similar in magnitude (both r2 = 0.01). Within individuals, increased TST (b = 0.06, p < 0.001), later wake time (b = 0.09, p < 0.001), earlier bedtime (b = − 0.07, p < 0.001), as well as lower day-to-day shifts in TST (b = −0.011, p < 0.001) and in wake time (b = −0.004, p < 0.001) were associated with improved next-day mood. Variability in sleep parameters substantially impacted mood and depression, similar in magnitude to the mean levels of sleep parameters. Interventions that target sleep consistency, along with sleep duration, hold promise to improve mental health.

0250 The Day-to-Day Associations Between Sleep Characteristics, Affect, and Affect Reactivity

Abstract Introduction Despite the high co-occurrence of sleep and mood disturbances, day-to-day associations between sleep characteristics (sleep duration, continuity, timing) and dimensions of mood (positive affect, PA, and negative affect, NA) remain unclear. Few field studies have tested whether sleep changes may affect mood by altering people’s emotional response to daily experiences outside the laboratory. The current study aimed to examine how sleep characteristics influence affective states and a measure of emotional response to daily experiences—affect reactivity. Methods Participants were healthy, midlife adults (30–54 yrs old, N =462, 47% male) drawn from the Adult Health and Behavior Project- Phase 2 study. Sleep was measured with actigraphy across a 4-day monitoring period; hourly self-report measures of affect, work demand, and social interactions were collected via ecological momentary assessment. Affect reactivity was quantified as hour-to-hour changes in affect following these daily experiences. We used hierarchical linear modeling to examine whether sleep characteristics on a given night predicted average daily affect and moderated affect reactivity the following day. Results When participants slept later than their average sleep time on a given night, they reported greater NA the following morning (before 12pm) and afternoon (12-6pm; B’s =.03, p’s&amp;lt;.05). When participants slept longer than their average sleep duration, they subsequently reported greater NA throughout the following day (B’s =.02, p’s&amp;lt;.05). Sleep efficiency was unrelated to affect report (p’s &amp;gt;.05). While episodes of greater work demand and social conflict predicted lower PA and higher NA (p’s&amp;lt;.05), participants’ sleep characteristics did not moderate these associations (p’s&amp;gt;.05). Conclusion Overall, our findings suggest proximal associations between sleep characteristics and next-day mood. While previous studies have shown effects of sleep disruptions on affect reactivity, we did not observe such associations in the context of small, day-to-day fluctuations in sleep characteristics among healthy individuals.

Daily Mood Reactivity to Stress during Childhood Predicts Internalizing Problems Three Years Later.

The mental health toll of common school problems that many children encounter every day is not well understood. This study examined individual differences in mood reactivity to naturally occurring school problems using daily diaries, and assessed their prospective associations with youth mental health, three years later. At baseline, 47 children ages 8 to 13years described common problems at school and mood on a daily basis, for 8weeks. Thirty-three youth returned for follow-up three years later at ages 11 to 17years. Children and parents also completed one-time questionnaires about youth mental health at baseline and follow-up. There were individual differences in the within-person associations between school problems and same-day and next-day mood. A greater tendency to react to school problems with more negative mood or less positive mood on the same day predicted more parent-rated internalizing and externalizing problems and child ratings of depression symptoms three years later, relative to baseline levels of symptoms. Daily diaries can help to identify specific targets of psychosocial interventions in real world settings.

Does it work and does it last? Effects of social and drinking behavior on same- and next-day mood

Both social and drinking behavior have the potential to modify mood. However, if social drinking enhances positive mood and reduces negative mood, as compared to non-drinking social behavior, then interventions to reinforce non-drinking via sober social activity are undermined. Using multilevel modeling analyses, we compared end-of-day mood on drinking days versus non-drinking days, and on days spent with other people as compared to days spent primarily alone. We evaluated the interaction between drinking/non-drinking and social/solitary behavior and assessed whether the effects of social and drinking behavior extended to mood the next day. Participants were 352 college students (53% female; 55% fraternity/sorority membership; mean age 19.7 years) who completed three automated telephone surveys each day during four 14-day intervals over 1 year. Drinking and being social were associated with higher end-of-day positive mood and significantly lower end-of-day negative mood. However, no positive enhancement or negative attenuation effects of alcohol were observed in interaction analyses. Alcohol provided no improvement in mood over-and-above being social at the end of the day or on the following day. However, drinking the previous day significantly reduced next-day positive mood, whereas being social significantly reduced next-day negative mood. These findings provide support for the reinforcing potential of interventions that increase rewarding social activity in the place of alcohol use.

Relationship Between Sleep Quality and Mood: Ecological Momentary Assessment Study.

BackgroundSleep disturbances play an important role in everyday affect and vice versa. However, the causal day-to-day interaction between sleep and mood has not been thoroughly explored, partly because of the lack of daily assessment data. Mobile phones enable us to collect ecological momentary assessment data on a daily basis in a noninvasive manner.ObjectiveThis study aimed to investigate the relationship between self-reported daily mood and sleep quality.MethodsA total of 208 adult participants were recruited to report mood and sleep patterns daily via their mobile phones for 6 consecutive weeks. Participants were recruited in 4 roughly equal groups: depressed and anxious, depressed only, anxious only, and controls. The effect of daily mood on sleep quality and vice versa were assessed using mixed effects models and propensity score matching.ResultsAll methods showed a significant effect of sleep quality on mood and vice versa. However, within individuals, the effect of sleep quality on next-day mood was much larger than the effect of previous-day mood on sleep quality. We did not find these effects to be confounded by the participants’ past mood and sleep quality or other variables such as stress, physical activity, and weather conditions.ConclusionsWe found that daily sleep quality and mood are related, with the effect of sleep quality on mood being significantly larger than the reverse. Correcting for participant fixed effects dramatically affected results. Causal analysis suggests that environmental factors included in the study and sleep and mood history do not mediate the relationship.

Sleep and mood during hospitalization for high-dose chemotherapy and hematopoietic rescue in pediatric medulloblastoma.

Disrupted sleep is common in pediatric cancer, which is associated with psychological distress and may impact neural recovery. Information regarding sleep during pediatric brain tumor treatment is limited. This study aimed to describe objective sleep-wake patterns and examine the sleep-mood relation in youth hospitalized for intensive chemotherapy and stem cell rescue. Participants included 37 patients (M age=9.6±4.2years) enrolled on a medulloblastoma protocol (SJMB03) and their parents. Respondents completed a mood disturbance measure on 3days, and patients wore an actigraph for 5days as an objective estimate of sleep-wake patterns. General linear mixed models examined the relation between nocturnal sleep and next-day mood, as well as mood and that night's sleep. Sleep duration was deficient, sleep efficiency was poor, and daytime napping was common, with large between-subjects variability. There were minimal mood concerns across all days. The sleep and next-day mood relationship was nonsignificant (P>.05). Greater parent-reported child mood disturbance on day 2 was associated with decreased same-night sleep (P<.001) and greater patient-reported mood disturbance was associated with greater same-night sleep latency (P=.036). Patients with medulloblastoma are vulnerable to disturbed sleep during hospitalization, and mood may be an important correlate to consider. Sleep and mood are modifiable factors that may be targeted to maximize daytime functioning.

A Daily Diary Investigation of the Influence of Early Family Adversity on Social Functioning during the Transition to Adulthood.

Early life stressors are associated with maladaptive social functioning in childhood and adolescence, but it is unclear whether and how the negative interpersonal effects of stress persist into adulthood. Daily diary surveys were used to examine young adults' social behavior and mood reactivity to social stressors as a function of experiences of early family adversity. Stressful early family environments predicted more daily reassurance seeking, but not aggression, withdrawal, or positive social behavior. Early family adversity also moderated the within-person effects of social stressors on next-day mood, such that individuals with high levels of adversity had elevated next-day negative affect in response to higher than average social stress. Findings highlight the enduring impact of early adversity on social development, with implications for developing targeted policies and interventions.

Individual Differences in Optimum Sleep for Daily Mood During Adolescence

Efforts to establish an empirical basis for recommended sleep durations during adolescence need to take into account individual differences in optimum sleep, defined as the amount of sleep at which peak functioning is observed. A total of 419 adolescents (M age = 15.03 years) with Mexican American backgrounds reported their nightly sleep duration and daily mood for a 2-week period at 1 or 2 waves of data collection, 1 year apart. Adolescents also completed an established measure of symptomatology. Multilevel modeling revealed a nonlinear association between sleep duration and next-day mood, whereby both too little and too much sleep were associated with elevated levels of daily distress. Significant individual differences in optimum sleep were observed such that younger adolescents and those with elevated levels of internalizing and total symptomatology evidenced greater sleep durations on nights before they reported their lowest levels of daily distress. Younger adolescents and those with higher internalizing and total symptomatology may need more sleep to reach their peak functioning the next day, at least in terms of daily mood.

Stress, Coping, and Mood Among Latino Adolescents: A Daily Diary Study.

The current study examines whether daily coping moderates the effects of daily stress on same-day mood and next-day mood among 58 Latino adolescents (Mage =13.31; 53% male). The daily diary design capitalized on repeated measurements, boosting power to detect effects and allowing for a robust understanding of the day-to-day experiences of Latino adolescents. Hierarchical linear modeling revealed that on days when youth reported higher levels of peer and academic stress, they also reported more negative moods. However, only poverty-related stress predicted mood the following day. Engagement coping buffered the effect of poverty-related stress on next-day negative and positive mood, while disengagement exacerbated the effects of academic and peer stress. The need for interventions promoting balanced coping repertoires is discussed.
