10. Screening for Sleep Reduction in Adolescents through Self-Report: Development and Validation of the Sleep Reduction Screening Questionnaire (SRSQ)

Author

Maanen, Annette, Dewald-Kaufmann, Julia F., and Oort, Frans J.

Abstract

Background: Sleep reduction, resulting from insufficient or poor sleep, is a common phenomenon in adolescents. Due to its severe negative psychological and behavioral daytime consequences, it is important to have a short reliable and valid measure to assess symptoms of sleep reduction. Objective: This study aims to validate the Sleep Reduction Screening Questionnaire (SRSQ) that can be used to screen for symptoms of sleep reduction in adolescents. Methods: Various samples from the general and clinical populations were included in the study. The SRSQ is a nine-item questionnaire that is based on the longer, four dimensional Chronic Sleep Reduction Questionnaire (Meijer in "J Sleep Res" 17:395-405, doi: 10.1111/j.1365-2869.2008.00677.x, 2008). Items were selected on the basis of principal components analysis, item-total correlations, and substantive consideration. The SRSQ was validated by calculating correlations with self-reported and objective sleep and self-reported daytime functioning. Cut-off scores were determined so that the SRSQ can be used as a screening instrument. Results: Internal consistencies of the SRSQ were good (Cronbach's alpha = 0.79 in the general population). Correlations with self-reported sleep, daytime functioning and objective sleep variables were satisfactory and in the expected directions. The SRSQ discriminates well between clinical and non-clinical cases. When accounting for prevalence of sleep reduction symptoms in the general population, the area under the curve was 0.91, sensitivity was 0.80 and specificity was 0.87. Conclusions: The SRSQ appears to be a short reliable and valid questionnaire. Due to the limited number of items and the availability of cut-off scores, it is a practical tool for clinical and research purposes.

Abstract

Adolescence is a time of increasing vulnerability for poor mental health, including depression. Sleep disturbance is an important risk factor for the development of depression during adolescence. Excessive electronic media use at night is a risk factor for both adolescents' sleep disturbance and depression. To better understand the interplay between sleep, depressive symptoms, and electronic media use at night, this study examined changes in adolescents' electronic media use at night and sleep associated with smartphone ownership. Also examined was whether sleep disturbance mediated the relationship between electronic media use at night and depressive symptoms. 362 adolescents (12-17year olds, M=14.8, SD=1.3; 44.8% female) were included and completed questionnaires assessing sleep disturbance (short sleep duration and sleep difficulties) and depressive symptoms. Further, participants reported on their electronic media use in bed before sleep such as frequency of watching TV or movies, playing video games, talking or text messaging on the mobile phone, and spending time online. Smartphone ownership was related to more electronic media use in bed before sleep, particularly calling/sending messages and spending time online compared to adolescents with a conventional mobile phone. Smartphone ownership was also related to later bedtimes while it was unrelated to sleep disturbance and symptoms of depression. Sleep disturbance partially mediated the relationship between electronic media use in bed before sleep and symptoms of depression. Electronic media use was negatively related with sleep duration and positively with sleep difficulties, which in turn were related to depressive symptoms. Sleep difficulties were the more important mediator than sleep duration. The results of this study suggest that adolescents might benefit from education regarding sleep hygiene and the risks of electronic media use at night.

Abstract

We aimed to obtain reliable reference charts for sleep duration, estimate the prevalence of sleep complaints across the lifespan and identify risk indicators of poor sleep. Studies were identified through systematic literature search in Embase, Medline and Web of Science (9 August 2019) and through personal contacts. Eligible studies had to be published between 2000 and 2017 with data on sleep assessed with questionnaires including ≥100 participants from the general population. We assembled individual participant data from 200,358 people (aged 1-100 years, 55% female) from 36 studies from the Netherlands, 471,759 people (40-69 years, 55.5% female) from the United Kingdom and 409,617 people (≥18 years, 55.8% female) from the United States. One in four people slept less than age-specific recommendations, but only 5.8% slept outside of the 'acceptable' sleep duration. Among teenagers, 51.5% reported total sleep times (TST) of less than the recommended 8-10 h and 18% report daytime sleepiness. In adults (≥18 years), poor sleep quality (13.3%) and insomnia symptoms (9.6-19.4%) were more prevalent than short sleep duration (6.5% with TST < 6 h). Insomnia symptoms were most frequent in people spending ≥9 h in bed, whereas poor sleep quality was more frequent in those spending <6 h in bed. TST was similar across countries, but insomnia symptoms were 1.5-2.9 times higher in the United States. Women (≥41 years) reported sleeping shorter times or slightly less efficiently than men, whereas with actigraphy they were estimated to sleep longer and more efficiently than man. This study provides age- and sex-specific population reference charts for sleep duration and efficiency which can help guide personalized advice on sleep length and preventive practices.

Abstract

Objectives: Previous research showed that positive and negative life events influence the development of depression. However, it is less clear how life events interact with depressive symptoms and self‐esteem. Design and methods: The present study aimed to investigate the mediating effects of self‐esteem on the relationship between life events and depressive symptoms in adulthood. The Traumatic Antecedent Questionnaire, Multidimensional Self‐esteem Scale (MSWS), and Becks Depression Inventory were administered in 173 psychiatric inpatients (mean age 39.69 ± 14.56 years, ranging from 18 to 76 years). At the time of assessment, all patients suffered from depressive symptoms caused by an affective disorder (major depression, bipolar I, dysthymia). Results: Path analyses showed that the individual level of self‐esteem (measured by MSWS) fully mediated the association between positive life events and depressive symptoms. Conclusions: The current study indicates that future therapy programmes for patients with depressive symptoms could include interventions focusing on the improvement of self‐esteem, as increasing self‐esteem may be beneficial for recovery. Practitioner points: To date, this is the first study exploring the pathways from positive/negative life events to depressive symptoms.The relationship between positive life experiences and depressive symptoms was fully mediated by self‐esteem.Strengthening self‐esteem in therapy might lower the vulnerability for depression.

Abstract

Background: Based on the vulnerability model, several studies indicate that low self-esteem seems to contribute to depressive symptoms. Aims: The aim of this study was to treat depressive symptoms in a cognitive behavioural group therapy, focusing on the enhancement of self-esteem, and to explore co-variation in depressive symptoms and the level of self-esteem. Method: The Multidimensional Self-esteem Scale (MSWS) and the Beck Depression Inventory (BDI) were administered to 147 psychiatric in-patients with current depressive symptoms due to an affective disorder (major depression, bipolar I, dysthymia). Self-esteem was measured pre-treatment (t0) and post-treatment (t4, after 5 weeks of eight group sessions); the BDI was applied weekly. A linear mixed growth analysis was conducted to estimate the change in depressive symptoms including interactions with self-esteem. Results: Within the 5 weeks of group therapy, depressive symptoms showed a linear decline, which was stronger for patients with higher gains in self-esteem between t0 and t4. Self-esteem at t0 was unrelated to the change in depression but predicted self-esteem at t4. Conclusions: Treating depressive symptoms in a cognitive behavioural group therapy in a naturalistic setting might have a positive effect on the process of recovery. Moreover, depressive symptoms and level of self-esteem seemed to co-vary. [ABSTRACT FROM AUTHOR]

Abstract

Sleep problems are prevalent in adolescents and can severely impair their daytime functioning. This study aims to investigate differences in daytime functioning (e.g., depressive symptoms, attention problems, school functioning, and school performance) between adolescents with high and low chronic sleep reduction and short and long sleep durations. With this approach we get a better idea of their vulnerability to impaired daytime functioning due to (chronic) sleep loss. From a total sample size of 794 adolescents, we selected the lowest and highest quartiles of adolescents with either low or high chronic sleep reduction and either short or long sleep durations. We found significant differences in daytime functioning between the different groups, giving evidence of vulnerability to impaired daytime functioning due to (chronic) sleep loss. The results are of high clinical relevance as they show that adolescents obtaining sufficient and/or good sleep show nearly no daytime functioning problems. Programs to improve adolescents' sleep are therefore highly recommended. [ABSTRACT FROM AUTHOR]

Abstract

Homeostatic and circadian changes that occur during adolescence can result in chronic sleep reduction. This may particularly be true for adolescents with Delayed Sleep Phase Disorder ( DSPD), which is associated with late Dim Light Melatonin Onset ( DLMO). This study assessed the influence of melatonin treatment on chronic sleep reduction in adolescents with DSPD and examined whether adolescents with DSPD suffer from more chronic sleep reduction than adolescents from the general population before and after melatonin treatment. Adolescents with DSPD ( n = 145; 55.9% boys; mean age 15,5 years; mean DLMO = 22:32 h) completed a questionnaire concerning chronic sleep reduction at baseline. From these, 53 adolescents also completed this questionnaire after on average 10 weeks of melatonin treatment. At baseline adolescents with DSPD reported significantly more symptoms of chronic sleep reduction than adolescents from the general population, whereas after treatment they reported significantly less symptoms. DLMO did not influence the effect of treatment. The improvement of chronic sleep reduction after treatment is an important finding, considering the negative consequences of chronic sleep reduction for adolescents' daytime functioning.

Abstract

Adolescence is a time of increasing vulnerability for poor mental health, including depression. Sleep disturbance is an important risk factor for the development of depression during adolescence. Excessive electronic media use at night is a risk factor for both adolescents' sleep disturbance and depression. To better understand the interplay between sleep, depressive symptoms, and electronic media use at night, this study examined changes in adolescents' electronic media use at night and sleep associated with smartphone ownership. Also examined was whether sleep disturbance mediated the relationship between electronic media use at night and depressive symptoms. 362 adolescents (12-17year olds, M=14.8, SD=1.3; 44.8% female) were included and completed questionnaires assessing sleep disturbance (short sleep duration and sleep difficulties) and depressive symptoms. Further, participants reported on their electronic media use in bed before sleep such as frequency of watching TV or movies, playing video games, talking or text messaging on the mobile phone, and spending time online. Smartphone ownership was related to more electronic media use in bed before sleep, particularly calling/sending messages and spending time online compared to adolescents with a conventional mobile phone. Smartphone ownership was also related to later bedtimes while it was unrelated to sleep disturbance and symptoms of depression. Sleep disturbance partially mediated the relationship between electronic media use in bed before sleep and symptoms of depression. Electronic media use was negatively related with sleep duration and positively with sleep difficulties, which in turn were related to depressive symptoms. Sleep difficulties were the more important mediator than sleep duration. The results of this study suggest that adolescents might benefit from education regarding sleep hygiene and the risks of electronic media use at night.
