A Pilot Study on Adolescents With Depression and Insomnia: Qualitative Findings From Focus Groups

The experience of sleep problems for adolescents with depression in short-term psychological therapy

A growing body of literature demonstrates a strong relationship between sleep disturbances and depression in adolescence. In spite of this, few studies have explored how adolescents with depression experience sleep problems. The present study aimed to qualitatively explore the experience of sleep problems in adolescents with depression, including their understanding of how a psychological therapy impacted on these sleep difficulties. The sample included 12 adolescents with sleep disturbances who had been offered treatment for depression through a large, multi-centre, randomised controlled trial. Semi-structured interviews conducted after treatment and 1-year post treatment were analysed using thematic analysis. Two main themes were identified. Both themes demonstrated how an overarching desire to escape impacted the adolescents' sleep in distinct ways; 'thinking about the 'bad stuff'' was characterised by ruminative thinking, which prevented sleep, whereas 'sleep as an escape' indicated a desire to sleep excessively due to feelings of helplessness. Overall, the findings demonstrate a nuanced relationship between sleep and depression in adolescence, and imply that the underlying meaning of the sleep difficulties for each young person should be considered in the delivery of therapy for adolescent depression.

Experience of Treatment and Adherence to Cognitive Behavioral Therapy for Insomnia for Patients with Depression: An Interview Study

OBJECTIVE/BACKGROUND

Research supports the efficacy of Cognitive Behavioral Therapy for Insomnia (CBT-I) for patients suffering from depression and insomnia, but little is known about how they experience treatment and adhere to it. Our objective, therefore, was to explore how patients with depression experience treatment components and how their experiences influence adherence to CBT-I as a full-package treatment.

PARTICIPANTS/METHODS

Twelve patients with depression and comorbid insomnia were interviewed after six sessions of CBT-I, and a conventional qualitative content analysis was conducted.

RESULTS

Two themes were found. The theme "I picked what I needed" showed that participants chose among CBT-I methods. Behavioral methods were considered hard but so effective that they reduced the need to learn other methods. Participants had difficulty learning cognitive methods, such as the restructuring of negative thoughts, owing to lack of energy and cognitive problems aggravated by sleep loss. Sleep hygiene education was regarded as common knowledge. The theme "Staying on track" highlighted factors promoting adherence, such as a preference for non-pharmacological treatment, rapid improvement, and support from relatives and therapists. Factors impeding adherence were: a perceived lack of support from the ongoing group setting, side effects of medication, changes in daily routine, and daytime fatigue influencing cognitive and emotional functioning.

CONCLUSION

The study suggests: focusing on adherence throughout treatment; actively using support from relatives and therapists; preferring individual treatment; and prioritizing behavioral treatment components, with cognitive components introduced later in the treatment course when the negative effects on cognitive functioning due to sleep restriction have diminished.

Association Between Major Depressive Disorder and Sleep Disturbances Through Inflammation in Adolescents

BACKGROUND

Although approximately 13% of adolescents suffer from Major Depressive Disorder (MDD), and many adolescents have reported sleep disturbances, the relationship between sleep disturbances and MDD in adolescents is poorly understood. Thus, our objective was to study how adolescent MDD was related to sleep disturbances in a cross-sectional study, and the potential role of inflammation linking adolescent MDD to sleep disturbances.

METHODS

Ninety-two female and male, African American and White, adolescents aged 15 to 18 years completed the study. Adolescents were diagnosed with MDD according to the Diagnostic and Statistical Manual of Mental Disorders-5 as confirmed by the MINI International Diagnostic Interview. The severity of depression was assessed using the Quick Inventory of Depressive Symptomatology. Sleep disturbance was measured using the Pediatric Sleep Questionnaires (PSQ). Blood sample was collected from each participant for measuring the inflammatory factors.

RESULTS

Compared with the controls (n=39), adolescents with MDD (n=53) had greater PSQ scores (0.32 ± 0.02 vs. 0.10 ± 0.02). In adolescents with MDD, PSQ scores were correlated with the severity of depressive symptoms (r=0.31, p<0.05). In addition, tumor necrosis factor-α levels were greatly elevated in the MDD group (2.4 ± 0.1 vs. 1.8 ± 0.1 pg/ml) compared with the controls. Severity of depressive symptoms was best predicted by PSQ scores, medications, and childhood experiences.

CONCLUSIONS

Sleep disturbance measured by the PSQ is associated with severe depressive symptoms in adolescents, and one potential pathway may be through elevated tumor necrosis factor-α. Further research is warranted to probe a cause and effect relationship among sleep disturbances, MDD, and chronic inflammation.

Insomnia disorder in adolescence: Diagnosis, impact, and treatment

Insomnia disorder is very common in adolescents; it is particularly manifest in older adolescents and girls, with a prevalence comparable to that of other major psychiatric disorders (e.g., depressive disorders). However, insomnia disorder in adolescence is poorly characterized, under-recognized, under-diagnosed, and under-treated, and the reason for the female preponderance for insomnia that emerges after puberty is largely unknown. Insomnia disorder goes beyond an individual complaint of poor sleep or a sleep state misperception, and there is emerging evidence supporting the association of insomnia symptoms in adolescents with alterations in several bio-systems including functional cortical alterations and systemic inflammation. Insomnia disorder is associated with depression and other psychiatric disorders, and is an independent risk factor for suicidality and substance use in adolescents, raising the possibility that treating insomnia symptoms in early adolescence may reduce risk for these adverse outcomes. Cognitive behavioral treatments have proven efficacy for adolescent insomnia and online methods seem to offer promising cost-effective options. Current evidence indicates that insomnia in adolescence is an independent entity that warrants attention as a public health concern in its own right.

The Experience of Sleep Problems and Their Treatment in Young People at Ultra-High Risk of Psychosis: A Thematic Analysis

We view sleep disruption as a contributory causal factor in the development of psychotic experiences. Clinical trials indicate that psychological interventions targeting insomnia result in improvements in both sleep and psychotic experiences. The aim of this study was to gain the perspective of young people at ultra-high risk of psychosis on their sleep problems and associated psychological treatment. Interviews were conducted with 11 patients, aged 15-22 years, at ultra-high risk of psychosis who had received a psychological sleep intervention. Responses were analyzed using thematic analysis. Disrupted sleep timing and a lack of routine were the characteristic hallmarks of participants' sleep problems. Sleep disturbance, psychological wellbeing, and functioning had a reciprocal relationship. There were negative expectations prior to therapy, however meaningful improvements occurred in sleep, mood, and functioning. The active implementation of therapy techniques was highlighted as important. These findings indicate that the treatment of sleep problems is highly valued and has a meaningful impact on wellbeing in young people at ultra-high risk of psychosis.

Dad's Snoring May Have Left Molecular Scars in Your DNA: the Emerging Role of Epigenetics in Sleep Disorders

The sleep-wake cycle is a biological phenomena under the orchestration of neurophysiological, neurochemical, neuroanatomical, and genetical mechanisms. Moreover, homeostatic and circadian processes participate in the regulation of sleep across the light-dark period. Further complexity of the understanding of the genesis of sleep engages disturbances which have been characterized and classified in a variety of sleep-wake cycle disorders. The most prominent sleep alterations include insomnia as well as excessive daytime sleepiness. On the other side, several human diseases have been linked with direct changes in DNA, such as chromatin configuration, genomic imprinting, DNA methylation, histone modifications (acetylation, methylation, ubiquitylation or sumoylation, etc.), and activating RNA molecules that are transcribed from DNA but not translated into proteins. Epigenetic theories primarily emphasize the interaction between the environment and gene expression. According to these approaches, the environment to which mammals are exposed has a significant role in determining the epigenetic modifications occurring in chromosomes that ultimately would influence not only development but also the descendants' physiology and behavior. Thus, what makes epigenetics intriguing is that, unlike genetic variation, modifications in DNA are altered directly by the environment and, in some cases, these epigenetic changes may be inherited by future generations. Thus, it is likely that epigenetic phenomena might contribute to the homeostatic and/or circadian control of sleep and, possibly, have an undescribed link with sleep disorders. An exciting new horizon of research is arising between sleep and epigenetics since it represents the relevance of the study of how the genome learns from its experiences and modulates behavior, including sleep.

Cognitive Behavioural Therapy for Insomnia in Psychiatric Disorders

Insomnia means difficulties in initiating or maintaining sleep and is commonly comorbid with psychiatric disorders. From being considered secondary to primary psychiatric disorders, comorbid insomnia is now considered an independent health issue that warrants treatment in its own right. Cognitive behavioural therapy for insomnia (CBT-I) is an evidence-based treatment for insomnia. The effects from CBT-I on comorbid psychiatric conditions have received increasing interest as insomnia comorbid with psychiatric disorders has been associated with more severe psychiatric symptomologies, and there are studies that indicate effects from CBT-I on both insomnia and psychiatric symptomology. During recent years, the literature on CBT-I for comorbid psychiatric groups has expanded and has advanced methodologically. This article reviews recent studies on the effects from CBT-I on sleep, daytime symptoms and function and psychiatric comorbidities for people with anxiety, depression, bipolar disorder, psychotic disorders and post-traumatic stress disorder. Future strategies for research are suggested.
