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. METHOD: Data was gathered from 179 participants with an anxiety disorder (11-17 years old) who had previously engaged with the out-patient child and adolescent mental health service. Baseline self-report measures of anxiety and depression symptoms, sleep patterns and experiences of insomnia were examined. Of this group, 135 participants had baseline data. A subset (n=73) had outcome data, which was used to examine changes in sleep following CBT. RESULTS: At baseline, adolescents reported significantly less total sleep and more night-time waking on weekdays than weekends. Following treatment for their anxiety disorder, adolescents' weekday sleep patterns significantly improved for sleep onset latency and total sleep time, whereas weekend sleep patterns only showed improvements for sleep onset latency. No significant improvements were reported for symptoms of insomnia. CONCLUSIONS: The study relied upon subjective measurement of sleep and there was no control group; however, the findings provide promising results that CBT for adolescent anxiety disorders can improve some sleep problems. Further research is needed to understand discrepancies between subjective and objective sleep, and to explore avenues for the delivery of support for sleep problems.

'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. This study aimed to generate and report on a list of words used by healthy adolescents and those with elevated depression symptoms to describe their self-evaluation. Linguistic analysis (LIWC) was then used to compare self-evaluation between the two groups. METHODS: Adolescents aged 13-18 years (n = 549) completed a measure of depression symptoms (the Mood and Feelings Questionnaire) and a measure of self-evaluation (the Twenty Statements Test). Responses were then collated and presented in a freely accessible resource and coded using Linguistic Inquiry Word Count (LIWC) analysis. RESULTS: Self-evaluation words generated by adolescents were uploaded to a publicly accessible site for future research: https://doi.org/10.15125/BATH-01234 . Adolescents with elevated depression symptoms described themselves as 'Tired' and 'Sad' more than healthy adolescents. However, there was no difference between groups in respect to their use of specific positive, prosocial self-evaluation 'words' (i.e., 'Caring' and 'Kind). Following Linguistic Inquiry Word Count (LIWC) analysis, adolescents with elevated depression symptoms generated significantly more words than healthy adolescents, generated more words classified as negative emotion, anxiety and sadness and generated fewer words classified positive emotion than healthy adolescents. CONCLUSIONS: As predicted by the cognitive model of depression, our findings suggest that adolescents with elevated symptoms of depression generated more negative self-evaluation words than healthy adolescents; however they also generated prosocial positive self-evaluation words at the same rate as non-depressed adolescents. These novel data therefore identify an 'island' of resilience that could be targeted and amplified by psychological treatments for adolescent depression, and thus provide an additional technique of change.

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. OBJECTIVE: To explore the user experience of a prototype online self-help single session sleep intervention developed for adolescents. METHODS: Eleven participants aged 17-19 years (8 females, 3 males) took part in online retrospective think-aloud interviews. Participants first completed the prototype intervention independently and were then shown the intervention page by page and asked to verbalise their thoughts and experiences. Transcripts were analyzed thematically. RESULTS: Participants found the intervention helpful. Four themes were generated - 'Educative: Learning, but more fun', 'Effortless: Quicker and Easier', 'Personalization: Power of Choice', and 'Positivity: Just Good Vibes'. The theme 'Educative: Learning, but more fun' encompassed two sub-themes 'Opportunity to Learn' and 'Aesthetics and Learning'. These themes reflected participants' views that the intervention was educative, personalised, solution-oriented and easy to use, but could incorporate more graphics and visuals to aid in learning and could be made more effortless and positive through modifications to its design. CONCLUSIONS: Findings convey the importance of ensuring educative well-designed content, personalization, a positive tone, and ease of use while designing interventions targeting adolescents's sleep and mental health. They also indicate areas for further developing the intervention.

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 (N = 7390). Children with speech sound disorder that had persisted beyond the period of typical speech acquisition (persistent speech disorder [PSD]) at age 8 were identified from recordings and transcriptions of speech samples (N = 263). Parent-, teacher- and child-reported questionnaires and interviews including the Strengths and Difficulties Questionnaire, Short Moods and Feelings Questionnaire and measures for antisocial and risk-taking behaviour were used to provide outcome scores for SEBD at 10-14 years in a series of regression analyses. Results: Following adjustment for biological sex, socio-economic status and Intelligence Quotient, children with PSD at age 8 were more likely to show peer problems at age 10-11 years compared with their peers, as reported by teachers and parents. Teachers were more likely to report problems with emotionality. Children with PSD were no more likely to report symptoms of depression than their peers. No associations were observed between PSD, risk of antisocial behaviour, trying alcohol at age 10 or smoking cigarettes at age 14. Conclusions: Children with PSD may be at risk in terms of their peer relationships. This could impact on their wellbeing and, while not observed at this age, may lead to depressive symptoms in older childhood and adolescence. There is also the potential that these symptoms may impact on educational outcomes.

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. A five-factor structure of the MFQ-C was confirmed through confirmatory factor analysis. A partial scalar invariant model was supported, and thus latent means were compared, with British adolescents reporting significantly higher mean MFQ-C scores than Thai adolescents on four of the five factors (Vegetative Symptoms, Suicidality, Cognitive Symptoms, Agitated Distress). There was no difference for the Core Symptoms factor. The findings also suggest that the MFQ-C is a valid measure to assess depression in Thai and British adolescents and maybe useful in cross-cultural comparisons of adolescent depression.

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. The search resulted in 8941 retrieved articles that were screened against an inclusion criteria. A total of 4 papers were included in the review. The MMAT used to assess study methodological quality. RESULTS: A narrative synthesis was conducted, and a summary figure was included. These 4 studies included 236 adolescents aged 9-18 years with depression and either Type 1 Diabetes (T1D), chronic pain, headaches, or Inflammatory Bowel Disease (IBD). The limited existing evidence indicated that that depression was associated with negative self-evaluation in adolescents in some but not all chronic illnesses investigated to date. We also found some evidence that psychological intervention can help to improve self-evaluation, specifically in adolescents with T1D. CONCLUSIONS: More robust studies of the association between self-evaluation and depression in adolescents with a chronic illness is needed, with attention to the nuances of differences between chronic illnesses. The existing evidence indicates that there may be a stronger association in some chronic illnesses. Pilot data suggest that specific psychological therapies may improve self-evaluation, although much more extensive evaluation is needed.

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. There were two conditions: (i) air purifier with a high-efficiency particulate air filter; (ii) air purifier with a placebo filter. Participants undertook both conditions, each over 2 weeks with a 2-week washout, following a counterbalanced, double-blind design. Daily sleep outcomes were measured with actigraphy watches and sleep diaries, whilst daily mood was assessed with the Positive and Negative Affect Schedule. The Insomnia Severity Index, the Pittsburgh Sleep Quality Index, and symptoms of anxiety and depression were measured pre- and post-. The purifier filter was associated with increased total sleep time for an average of 12 min per night, and increased total time in bed for an average of 19 min per night relative to the placebo. There were several sleep and mood outcomes for which no changes were observed, and time awake after sleep onset was higher for the purifier filter. Air quality was better during the high-efficiency particulate air filter condition. These findings offer positive indications that environmental interventions that improve air quality can have benefits for sleep outcomes in healthy populations who are not exhibiting clinical sleep disturbances.

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. 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.

Depression symptom clusters in adolescents: A latent class analysis in a clinical sample.

BACKGROUND: Major depression is clinically heterogeneous. We aimed to identify classes of depressed adolescents with different symptom presentations and examine if these were differentially associated with illness severity, functioning, engagement with treatment, and clinical outcomes. METHOD: Baseline depression symptoms of 454 depressed adolescents (age 11-17) from the IMPACT trial were subjected to latent class analysis. We compared classes on self-reported symptoms and social impairment at baseline and follow-up and their engagement in treatment. RESULTS: We identified three classes of participants which differed in the number and pattern of depression symptoms; Class 1-Severe- (37.2%)-endorsed almost all symptoms and were most functionally impaired; Class 2-Moderate- (41.9%)-endorsed fewer symptoms with high suicidal ideation, self-harm, and worthlessness; Class 3-Somatic (20.9%)-endorsed fewest symptoms, with high somatic symptoms. Groups did not differ on engagement, therapeutic alliance, or post-treatment symptom reduction. Adolescents in the severe and moderate subgroups reported symptom reductions after treatment ended, whilst those in the somatic subgroup did not. CONCLUSIONS: At presentation, high somatic features in depressed adolescents, rather than severity, or impairment levels, may indicate lower liability for responding to psychological treatment.

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. The aim of this meta-analysis was to review whether non-pharmacological sleep interventions have an impact on anxiety symptoms immediately post-intervention. A systematic search of electronic databases was conducted to identify all randomized control trials (RCTs) investigating non-pharmacological sleep interventions that included anxiety symptoms as an outcome. Forty-three RCTs (n = 5945) met full inclusion criteria and were included in a random-effects meta-analysis model. The combined effect size of non-pharmacological sleep interventions on anxiety symptoms was moderate (Hedges' g = -0.38), indicating a reduction in symptoms. Subgroup analyses found a moderate effect for those with additional physical health difficulties (g = -0.46), a moderate effect for those with additional mental health difficulties (g = -0.47) and a moderate effect for those with elevated levels of anxiety at baseline (g = -0.43). A secondary meta-analysis found a large effect of non-pharmacological sleep interventions on sleep-related thought processes (g = -0.92). These findings indicate non-pharmacological sleep interventions are effective in reducing anxiety and sleep-related thought processes, and these effects may be larger in patients with anxiety. This has clinical implications for considering sleep interventions in the treatment of anxiety.

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. In-depth qualitative interviews were conducted one-to-one with each adolescent and adolescents' parents were interviewed separately for the purpose of data triangulation. Data were analysed using reflexive thematic analysis. We identified four themes capturing adolescent perceived barriers and facilitators to seeking/accessing professional help for anxiety and depressive disorders: (1) making sense of difficulties, (2) problem disclosure, (3) ambivalence to seeking help, and (4) the instrumental role of others. Barriers/facilitators identified within each theme reflect important developmental characteristics of adolescence, such as a growing need for autonomy and concerns around negative social evaluation. At the same time, the results highlight adolescents' dependency on other people, mainly their parents and school staff, when it comes to successfully accessing professional help for their mental health difficulties. This study identifies a number of barriers/facilitators that influence help-seeking behaviour of adolescents with anxiety and/or depressive disorders. These factors need to be addressed when targeting treatment utilisation rates in this particular group of young people.

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. The aim of this review was to examine self-evaluation as a characteristic of adolescent depression, and as an active ingredient in treatment for adolescent depression. METHODS: We conducted a scoping review which included quantitative and qualitative studies of any design that reported on self-evaluation as a characteristic of, or focus of treatment for, adolescent depression. Participants were required to be 11-24 years and experiencing elevated symptoms of depression or a diagnosis. We also met with 14 expert advisory groups of young people with lived experience, clinicians, and researchers, for their input. Findings from 46 peer-reviewed research studies are presented alongside views of 64 expert advisors, to identify what is known and what is missing in the literature. RESULTS: Three overarching topics were identified following the review and reflections from advisors: 1) What does it look like? 2) Where does it come from? and 3) How can we change it? The literature identified that young people view themselves more negatively and less positively when depressed, however expert advisors explained that view of self is complex and varies for each individual. Literature identified preliminary evidence of a bidirectional relationship between self-evaluation and depression, however, advisors raised questions regarding the influences and mechanisms involved, such as being influenced by the social environment, and by the cognitive capacity of the individual. Finally, there was a consensus from the literature and expert advisors that self-evaluation can improve across treatment. However, research literature was limited, with only 11 identified studies covering a diverse range of interventions and self-evaluation measures. Various barriers and facilitators to working on self-evaluation in treatment were highlighted by advisors, as well as suggestions for treatment approaches. CONCLUSIONS: Findings indicate the importance of self-evaluation in adolescent depression, but highlight the need for more research on which treatments and treatment components are most effective in changing self-evaluation.

Using the 11-item Version of the RCADS to Identify Anxiety and Depressive Disorders in Adolescents.

The purpose of this study was to identify items from the Revised Children's Anxiety and Depression Scale - RCADS-C/P that provided a brief, reliable and valid screen for anxiety and/or depressive disorders in adolescents. In addition, we examined whether adding items assessing suicidal ideation (Moods and Feelings Questionnaire - MFQ- C/P) and symptom impact and duration (items adapted from the Strengths and Difficulties Questionnaire - SDQ) improved the identification of adolescents with anxiety and/or depressive disorders. We compared two samples of adolescents and their parents - a community sample, recruited through secondary schools in England (n = 214) and a clinic-referred sample, who met diagnostic criteria for anxiety and/or depressive disorder and were recruited through a university-based research clinic (n = 246). Participants completed the RCADS-C/P with additional symptom impact and duration items, and the MFQ-C/P. Using ROC curve analyses, we identified a set of 11 RCADS-C/P items (6 addressing anxiety and 5 depression symptoms) for adolescent- and parent-report. This set of 11 symptom items achieved sensitivity/specificity values > .75, which were comparable to corresponding values for the RCADS-47-C/P. Combining adolescent and parent-report improved the identification of anxiety/depression in adolescents compared to using adolescent-report alone. Finally, adding two symptom impact items further improved the sensitivity/specificity of the 11 symptom items, whereas adding suicidal ideation items did not. The 11 RCADS items accurately discriminated between the community and clinic-referred sample with anxiety and/or depressive disorders and have the potential to quickly and accurately identify adolescents with these disorders in community settings.

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. In part 1, The MFQ was translated and back translated into the Thai language and piloted on a small number of Thai adolescents. Then 1275 young people aged 12-18 years from three secondary schools in Thailand completed the MFQ and related measures of depression. In part 2, 138 students were invited to take part in a structured diagnostic interview (the Thai translation of the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children -Present and Lifetime Version (the K-SADS-PL). Of those, 103 students were interviewed and completed the Thai MFQ a second time to assess test-retest reliability. Receiver Operating Characteristics (ROC) analyses were conducted to evaluate diagnosis accuracy and examine the optimal cut-off score of the Thai MFQ. RESULTS: The Thai MFQ had excellent internal consistency (α = 0.92) and good to moderate test-retest reliability in 2-week and 4-week intervals. The Thai MFQ also had good convergent validity with related measures of depression. The ROC analyses demonstrated that the Thai MFQ also had excellent accuracy distinguishing between depressed and non-depressed adolescents [AUC = 0.95, 95% CI [0.92, 0.99]. A total score of 28 on the Thai MFQ was the optimal cut-off score (sensitivity was 0.97 and specificity was 0.83). DISCUSSION: The Thai MFQ demonstrated excellent psychometric properties and accurately distinguished between depressed and non-depressed adolescents. It is appropriate to use as a screening measure to identify adolescents with depression in community settings in Thailand.

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.

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. METHOD: The sample was derived from the Avon Longitudinal Study of Parents and Children (ALSPAC), a population-based, prospective, birth cohort study of children born in 1991-1992. Data were explored from a subset of participants who took part in a clinical assessment at age 15, on self-report sleep patterns and quality, and diagnostic outcomes of anxiety and depression (N = 5,033). Subsequent diagnostic and symptom severity data on anxiety and depression at ages 17, 21 and 24 were also examined. RESULTS: Cross-sectional and longitudinal analyses were conducted to explore the relationship between sleep problems, anxiety and depression. Results revealed that adolescents aged 15 with depression experience difficulties with both sleep patterns and sleep quality, whereas adolescents with anxiety only reported problems with sleep quality. A range of sleep variables at age 15 predicted the severity of anxiety and depression symptoms and the diagnoses of anxiety and depressive disorders at age 17, 21 and 24 years. CONCLUSIONS: The results provide further insight into the nature of sleep problems amongst adolescents with anxiety and depression, and the prospective relationship between sleep disturbance and future psychopathology. These data suggest that targeting sleep difficulties during adolescence may have long-term mental health benefits.

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. METHODS: Eight electronic databases were systematically searched from inception to April 2019 for eligible trials. Study quality was assessed using two scales designed to evaluate psychotherapy intervention trials. Random effects meta-analyses were conducted separately for trials that recruited participants based on symptoms of depression and based on symptoms of anxiety. RESULTS: Data from 45 trials were analysed. Most interventions studied used cognitive and behavioural strategies. Few studies met methodological quality criteria, but effect size was not associated with study quality. Indicated school-based interventions had a small effect on reducing depression symptoms (SMD = .34, 95% CI -0.48, -0.21) and a medium effect on reducing anxiety symptoms (SMD = -.49, 95% CI -0.79, -0.19) immediately postintervention. Subgroup analyses indicated that interventions delivered by internal school staff did not have significant effects on symptoms. Reductions in depression were maintained at short-term (≤6 months) but not medium (>6 months ≤ 12) or long-term (>12-month) follow-up. Reductions in anxiety symptoms were not maintained at any follow-up. CONCLUSIONS: Indicated school-based interventions are effective at reducing symptoms of depression and anxiety in adolescents immediately postintervention but there is little evidence that these reductions are maintained. Interventions delivered by school staff are not supported by the current evidence base. Further high-quality randomised controlled trials incorporating assessment of longer-term outcomes are needed to justify increased investment in school-based interventions for adolescent depression and 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., 2017b). Young people aged 12-18 years (N = 465; 75% female) met diagnostic criteria for Major Depressive Disorder, based on the Kiddie-Schedule for Affective Disorders and Schizophrenia (K-SADS). They were randomised to one of three psychological treatments. Sleep difficulties were assessed at baseline, post-treatment (36 weeks) and one year follow up (86 weeks) with the K-SADS, and the Mood and Feelings Questionnaire (MFQ). RESULTS: At baseline, 92% of young people exhibited clinically significant sleep difficulties. Exploratory analyses suggest that sleep difficulties significantly decreased from baseline to end of treatment on self-report and interview-based measures, and this decrease was maintained at follow up. Reduction in sleep difficulties did not differ between the psychological treatments. Approximately, half of young people reported residual sleep difficulties at the end of treatment and at follow-up. LIMITATIONS: This paper reports secondary data analyses and findings are exploratory. CONCLUSIONS: Tentative results suggest that psychological treatments for depression reduced sleep problems for some participants. However, young people with treatment-resistant sleep problems may benefit from adjunctive sleep interventions. Future work with a range of sleep measures is needed to determine those who have residual sleep problems at the end of treatment and post-treatment follow-up.

Examining parent and child agreement in the diagnosis of adolescent depression.

BACKGROUND: The diagnosis of depression in adolescents relies on identifying the presence of specific core and additional symptoms. Symptoms can be identified using structured or unstructured interviews and a range of questionnaire measures, which are completed by the young person and by a parent or carer. The aim of this research was to examine the inter- and intra-rater reliability of parent report and adolescent self-report of depression symptoms. METHOD: In a sample of parent-child dyads, where young people aged 13-17 were referred to a mental health service for depression, we examined adolescents' (n = 46) and parents' (n = 46) independent responses to the Schedule for Affective Disorders and Schizophrenia in School-Age Children (Journal of the American Academy of Child and Adolescent Psychiatry, 36, 1997, 980) and the Mood and Feelings Questionnaire (Journal of the American Academy of Child and Adolescent Psychiatry, 27, 1988, 726). RESULTS: In the clinical interview, diagnostic criteria were more often met based on the adolescent's report, and adolescents endorsed more symptoms of depression than their parents. Tentative results also suggest that parent-child agreement about specific symptoms was low. Comparing different measures of depression revealed that adolescent report on the questionnaire and interview was significantly correlated. However, there was no significant correlation between parent questionnaire and interview report. CONCLUSION: These results suggest that relying solely on parents to identify depression in their children may result in young people with depression being missed and therefore untreated. Young people themselves should be encouraged and enabled to recognise the symptoms of depression and have an established pathway to services that offer assessment and treatment. Key Practitioner Message Diagnosis of depression in adolescents requires the identification of specific symptoms and can be identified using interviews or questionnaires. Previous research has suggested that parents and young people provide differing reports regarding symptoms of adolescent depression. Results indicated that diagnostic criteria were more often met based on young person report and that parents reported significantly less symptoms. Parent-child agreement about specific symptoms was found to be low. Assessment of adolescent depression should not rely solely on parental report. Young people should be encouraged and enabled to recognise symptoms of depression and be able to access mental health services.
