Changes to sleep patterns and insomnia symptoms following cognitive behavioural therapy for anxiety disorders in adolescents.

Background: It is unclear whether treatment for an anxiety disorder improves sleep. This study examined baseline sleep characteristics of adolescents with an anxiety disorder, comparing weekdays and weekends, and whether there were significant improvements in sleep following cognitive behaviour therapy (CBT).

Aims: To improve our understanding of sleep problems in adolescents with an anxiety disorder and examine whether CBT for the treatment of the anxiety disorder improves sleep.

How do adolescents experience a newly developed Online Single Session Sleep Intervention? A Think-Aloud Study.

Background: Sleep problems are common in adolescents and have detrimental impacts on physical and mental health and daily functioning. Evidence-based treatment like cognitive behaviour therapy for insomnia (CBT-I) is often hard to access, and adolescents may not engage in and adhere to longer, clinician-delivered interventions. Brief, self-guided, and accessible sleep interventions are needed.

'I am tired, sad and kind': self-evaluation and symptoms of depression in adolescents.

Introduction: Although self-evaluation i.e., negative perceptions of the self is a common depression symptom in adolescents, little is known about how this population spontaneously describe their self and available data on adolescent self-evaluation is limited.

Factor structure and measurement invariance of the Mood and Feelings Questionnaire: a cross-cultural study among Thai and British adolescents.

The Mood and Feelings Questionnaire-child self-report (MFQ-C) is a widely used measure of child and adolescent depression. This study evaluated possible factor solutions and examined the measurement invariance of the MFQ-C as a prerequisite for its use in cross-cultural comparisons between Thai (N = 1272) and British samples (N = 1817) by using multigroup confirmatory factor analysis (MGCFA). The latent means of Thai and British samples were also examined.

Social, emotional and behavioural difficulties associated with persistent speech disorder in children: A prospective population study.

Purpose: Social, emotional and behavioural difficulties (SEBD) in childhood are associated with negative consequences across the life course. Children with developmental language disorder have been identified as being at risk of developing SEBD but it is unclear whether a similar risk exists for children with speech sound disorder, a condition which impacts on children's ability to make themselves understood and has been shown to be associated with poor educational outcomes.

Methods: Participants were children who attended the 8-year-old clinic in the Avon Longitudinal Study of Parents and Children ( = 7390).

Can air purification improve sleep quality? A 2-week randomised-controlled crossover pilot study in healthy adults.

Insufficient quantity and quality of sleep is a public health concern that can be addressed by interventions for improving sleep outcomes. Environmental factors such as poor air quality are a potential target for intervention, particularly in light of associations between air pollution and worse sleep. The aim of this pilot study was to investigate the effects of using an air purifier on sleep outcomes and mood in 30 healthy adults.

Self-evaluation and depression in adolescents with a chronic illness: A systematic review.

Objective: To conduct a systematic review to establish what is known about the relationship between depression and self-evaluation in adolescents with a chronic illness.

Methods: A systematic search was conducted using MEDLINE, EMBASE, PsycINFO, Web of Science, The Cochrane Library, and hand-searching. We sought to identify primary research that examined both the cross-sectional and longitudinal associations between depression and self-evaluation in adolescents with chronic illness.

Sleep's role in the development and resolution of adolescent depression.

Two adolescent mental health fields - sleep and depression - have advanced largely in parallel until about four years ago. Although sleep problems have been thought to be a symptom of adolescent depression, emerging evidence suggests that sleep difficulties arise before depression does. In this Review, we describe how the combination of adolescent sleep biology and psychology uniquely predispose adolescents to develop depression.

Self-evaluation as an active ingredient in the experience and treatment of adolescent depression; an integrated scoping review with expert advisory input.

Background: Negative self-perceptions is one of the most common symptoms of depression in young people, and has been found to be strongly associated with severity of depression symptoms. Psychological treatments for adolescent depression are only moderately effective. Understanding the role and importance of these self-perceptions may help to inform and improve treatments.

Do non-pharmacological sleep interventions affect anxiety symptoms? A meta-analysis.

Research indicates a bidirectional relationship between sleep and anxiety, with findings suggesting anxiety can precede poor sleep and vice versa. Evidence suggests sleep-related thought processes associated with anxiety are involved in the maintenance of insomnia. Previous meta-analyses provide some evidence to suggest cognitive behavioural therapy for insomnia moderately improves anxiety, yet little research has investigated the effect of other sleep interventions on anxiety symptoms.

Psychometric properties of the Thai Mood and Feelings Questionnaire (MFQ) for adolescent depression.

Background: The Mood and Feelings Questionnaire (MFQ) is a widely used screening tool for child and adolescence depression but has not been validated with young people in Thailand. This study aimed to assess the reliability and validity and to determine the optimal clinical cut-off of the Thai MFQ.

Methods: The Thai MFQ was evaluated in two parts.

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.

Adolescents' perceived barriers and facilitators to seeking and accessing professional help for anxiety and depressive disorders: a qualitative interview study.

Anxiety and depressive disorders are the most common mental health disorders in adolescents, yet only a minority of young people with these disorders access professional help. This study aims to address this treatment gap by improving our understanding of barriers and facilitators to seeking/accessing professional help as perceived by adolescents with anxiety/depressive disorders identified in the community. Twenty-two adolescents, aged 11-17 years, who met diagnostic criteria for a current anxiety and/or depressive disorder were identified through school-based screening.

Self-reported sleep patterns and quality amongst adolescents: cross-sectional and prospective associations with anxiety and depression.

Background: Sleep problems are common in adolescence, and frequently comorbid with both anxiety and depression. Research studies have suggested a bidirectional relationship between sleep and psychopathology, which includes evidence that sleep interventions can alleviate symptoms of anxiety and depression. However, little is known about the nature of sleep problems amongst adolescents with anxiety and depression, and whether specific sleeping difficulties are involved in the longitudinal relationship between sleep, anxiety and depression.

Practitioner Review: Effectiveness of indicated school-based interventions for adolescent depression and anxiety - a meta-analytic review.

Background: Interest in delivering psychological interventions within schools to facilitate early intervention is increasing. However, most reviews have focused on universal or preventative programmes rather than interventions designed to decrease existing symptoms of depression or anxiety. This paper aims to provide a meta-analytic review of randomised controlled trials of indicated psychological interventions for young people aged 10-19 with elevated symptoms of depression and/or anxiety.

Do sleep disturbances in depressed adolescents improve following psychological treatment for depression?

Background: Persistent sleep disturbances are one of the most common symptoms of Major Depressive Disorder (MDD) in adolescence. These are not typically targeted in psychological treatments and it is not known if psychological treatment for depression improves sleep.

Methods: Secondary analyses were conducted using data from a large, multi-centre, randomised controlled trial (Goodyer et al.

The effect of non-pharmacological sleep interventions on depression symptoms: A meta-analysis of randomised controlled trials.

Poor sleep is a significant risk factor for depression across the lifespan and sleep problems have been hypothesised to contribute to the onset and maintenance of depression symptoms. However, sleep problems are usually not a direct target of interventions for depression. A range of non-pharmacological treatments can reduce sleep problems but it is unclear whether these interventions also reduce other depression symptoms.

'I Am Worthless and Kind'; the specificity of positive and negative self-evaluation in adolescent depression.

Objectives: Adolescence represents a critical phase when the concept of self is developed and consolidated. Depressed adolescents globally endorse more negative and fewer positive self-descriptive words compared with non-depressed adolescents. Yet, the methods used have not allowed for more detailed exploration of the specific content of these self-endorsements.

Cognitive biases predict symptoms of depression, anxiety and wellbeing above and beyond neuroticism in adolescence.

Background: Adolescence represents a period of vulnerability to affective disorders. Neuroticism is considered a heritable risk factor for depression, but is not directly amenable to intervention. Therefore, it is important to identify the contributions of modifiable risk factors.

The combined influence of cognitions in adolescent depression: Biases of interpretation, self-evaluation, and memory.

Objectives: Depression is characterized by a range of systematic negative biases in thinking and information processing. These biases are believed to play a causal role in the aetiology and maintenance of depression, and it has been proposed that the combined effect of cognitive biases may have greater impact on depression than individual biases alone. Yet little is known about how these biases interact during adolescence when onset is most common.

Clinical characteristics of adolescents referred for treatment of depressive disorders.

Background: Adolescence is a period of increased risk for the development of depression. Epidemiological and clinical studies suggest that the phenomenology of depression may differ during childhood and adolescence. However, participants in these studies may not reflect depressed young people referred to routine clinical services.
