The therapeutic potential of attentional bias modification training for insomnia: study protocol for a randomised controlled trial.

The efficacy of attentional bias modification (ABM) as a treatment for anxiety and depression has been extensively studied with promising results. Despite some evidence of sleep-related attentional biases in insomnia, only a small number of studies, yielding mixed results, have examined the application of ABM in insomnia. This study specifically aims to determine whether ABM can reduce (i) the presence of an attentional bias for sleep-related threatening words; (ii) insomnia symptom severity; (iii) sleep onset latency; and (iv) pre-sleep cognitive arousal amongst individuals with insomnia compared to a non-treatment control group of individuals with insomnia. We propose a randomised controlled trial of 90 individuals from the general population who meet the criteria for Insomnia Disorder. Following an initial examination for the presence of a sleep-related attentional bias using the dot-probe paradigm, participants will be randomised to an online attentional bias modification training condition, or to a standard attentional bias task (non-treatment) control condition. Both conditions will be delivered online by a web platform. All participants allocated to the non-treatment control group will be offered ABM training once the study is complete. The primary outcome will be the attentional bias indices of vigilance and disengagement and self-reported insomnia symptoms, sleep onset latency and pre-sleep cognitive arousal. Attentional bias and insomnia symptoms will be assessed at baseline (day 1) and post-treatment (2 days after the final training session: day 9). Insomnia symptoms will be again assessed at follow-up (day 16). Secondary outcomes include examining whether sleep associated monitoring and worry are related to a sleep-related attentional bias in insomnia, and whether such reports reduce following ABM. All main analyses will be carried out on completion of follow-up assessments. The trial is supported by the Department of Psychology, Sociology and Politics at Sheffield Hallam University. This study will extend the research base examining the efficacy of attentional bias modification for insomnia. ISRCTN ( ISRCTN11643569 , registered on 5 June 2018)

Is burnout a depressive condition? A 14-sample meta-analytic and bifactor analytic study

There is no consensus on whether burnout constitutes a depressive condition or an original entity requiring specific medical and legal recognition. In this study, we examined burnout–depression overlap using 14 samples of individuals from various countries and occupational domains (N = 12,417). Meta-analytically pooled disattenuated correlations indicated (a) that exhaustion—burnout’s core—is more closely associated with depressive symptoms than with the other putative dimensions of burnout (detachment and efficacy) and (b) that the exhaustion–depression association is problematically strong from a discriminant validity standpoint (r = .80). The overlap of burnout’s core dimension with depression was further illuminated in 14 exploratory structural equation modeling bifactor analyses. Given their consistency across countries, languages, occupations, measures, and methods, our results offer a solid base of evidence in support of the view that burnout problematically overlaps with depression. We conclude by outlining avenues of research that depart from the use of the burnout construct

Effectiveness of multimodal treatment for young people with body dysmorphic disorder in two specialist clinics

Body dysmorphic disorder (BDD) typically originates in adolescence and is associated with considerable adversity. Evidence-based treatments exist but research on clinical outcomes in naturalistic settings is extremely scarce. We evaluated the short- and long-term outcomes of a large cohort of adolescents with BDD receiving specialist multimodal treatment and examined predictors of symptom improvement. We followed 140 young people (age range 10-18) with a diagnosis of BDD treated at two national and specialist outpatient clinics in Stockholm, Sweden (n=96) and London, England (n=44), between January 2015 and April 2021. Participants received multimodal treatment consisting of cognitive behaviour therapy and, in 72% of cases, medication (primarily selective serotonin reuptake inhibitors). Data were collected at baseline, post-treatment, and 3, 6, and 12 months after treatment. The primary outcome measure was the clinician-rated Yale-Brown Obsessive-Compulsive Scale Modified for BDD, Adolescent version (BDD-YBOCS-A). Secondary outcomes included self-reported measures of BDD symptoms, depressive symptoms, and global functioning. Mixed-effects regression models showed that BDD-YBOCS-A scores decreased significantly from baseline to post-treatment (coefficient [95% confidence interval]=-16.33 [-17.90 to -14.76], p<0.001; within-group effect size (Cohen’s d)=2.08 (95% confidence interval, 1.81 to 2.35). At the end of the treatment, 79% of the participants were classified as responders and 59% as full or partial remitters. BDD symptoms continued to improve throughout the follow-up. Improvement was also seen on all secondary outcome measures. Linear regression models identified baseline BDD symptom severity as a predictor of treatment outcome at post-treatment, but no consistent predictors were found at the 12-month follow-up. To conclude, multimodal treatment for adolescent BDD is effective in both the short- and long-term when provided flexibly within a specialist setting. Considering the high personal and societal costs of BDD, specialist care should be made more widely available

Anxiety and depression mediate the relationship between insomnia symptoms and the personality traits of conscientiousness and emotional stability

This study examined the relationship between the Big Five personality traits and insomnia symptoms in the general population. Additionally, the mediating role of anxiety and depression was examined. Participants (N=625) completed online measures of the big five personality traits and insomnia severity. Insomnia symptoms were independently related to extroversion, agreeableness, conscientiousness, emotional stability, anxiety and depression in univariate analysis. Linear regression determined conscientiousness and emotional stability to be the only traits predicting insomnia symptoms. However, these relationships were at least partially mediated by anxiety and depression. Whilst reduced levels of conscientiousness and emotional stability has previously associated with poor sleep and insomnia, the current outcomes shed light on the mechanisms which serve to mediate this relationship

Sleep-related attentional bias in insomnia: time to examine moderating factors?

Prominent cognitive models of insomnia have emphasized the notion that the disorder is in part maintained by an attentional bias for sleep related “threat” cues which may be internal (i.e., bodily sensations) or external (i.e., environmental) in nature (Harvey, 2002; Espie et al., 2006). To support this proposition, a growing number of studies have examined the presence of a sleep-related attentional bias for words and images using experimental tasks including the dot-probe, flicker, Posner, emotional Stroop, and eye-tracking paradigms (see Harris et al., 2015 for a review). Many of these studies have provided encouraging evidence for the presence of such a bias in insomnia. However, the evidence base advocating the presence of such a bias remains mixed with a number of studies yielding no statistically significant effects. While a recent review (Harris et al., 2015) cautiously suggests biased attention for sleep-related threat information to be a likely feature of insomnia, the authors highlight the need to understand the specificity of this bias and its relationship with mechanisms believed to underpin the disorder (e.g., sleep preoccupation). Furthermore, whilst it is possible that the mixed evidence may stem from methodological differences relating to the task or population used, the possible moderating influence of these factors on the relationship between attentional bias for sleep-related threat information and insomnia have only recently been examined (e.g., Zheng et al., 2018). With this in mind, we propose candidate factors that may play a crucial role in addressing moderating questions such as “when,” “for whom” and “under which” conditions are sleep-related attentional biases evident in individuals characterized by insomnia

A cross-sectional survey of the nature and correlates of sleep disturbance in people with psoriasis

BACKGROUND: Research suggests that sleep disturbance is common in psoriasis. Despite 32 studies conducted in sleep, many demonstrate methodological flaws, often using unvalidated measurement, with no study examining multiple dimensions of sleep-wake functioning. Moreover, research has yet to comprehensively examine the range of physical and psychological factors that may affect sleep in people with psoriasis. OBJECTIVE: To characterise sleep disturbance using validated measures and identify physical and psychological predictors of sleep quality in people with psoriasis. METHODS: An online survey was conducted (n=186;Mage =39.2) comprising validated measures assessing sleep (Pittsburgh Sleep Quality Index [PSQI], Berlin Questionnaire, Pre-Sleep Arousal Scale), chronotype (Morningness-Eveningness Questionnaire), mood (Hospital Anxiety and Depression Scale), itch (5-D Itch Scale) and psoriasis severity (Simplified Psoriasis Index). Group comparisons and regression analyses were used to examine predictors of poor sleep. RESULTS: Mean PSQI score was 9.24 (SD=4.32), with 76.3% scoring above the threshold for poor sleep (≥ 6 on the PSQI) and 32.5% scoring 'positive' for probable obstructive sleep apnoea. Poor sleep and high likelihood of OSA was associated with more severe psoriasis (p<.05; η(2) =.07; η(2) =.005). Cognitive arousal (β=.264, p=.001), itch (β=.260, p<.001) and depression (β=.236, p=.001) were the most robust predictors of poor sleep quality which, together with somatic arousal (β=.168, p=.022), accounted for 43% of variance in PSQI scores. CONCLUSIONS: Poor sleep is common in psoriasis and associated with psychological and physical factors. Rates of probable obstructive sleep apnoea are also high. Given the importance of restorative sleep for health, sleep complaints should receive greater clinical attention in the management of psoriasis. This article is protected by copyright.

Burnout and Depression: Two Entities or One

Objectives: The purpose of this study was to examine the overlap in burnout and depression. Method: The sample comprised 1,386 schoolteachers (mean age = 43; mean years taught = 15; 77% women) from 18 different U.S. states. We assessed burnout, using the Shirom-Melamed Burnout Measure, and depression, using the depression module of the Patient Health Questionnaire. Results: Treated dimensionally, burnout and depressive symptoms were strongly correlated (.77; disattenuated correlation, .84). Burnout and depressive symptoms were similarly correlated with each of 3 stress-related factors, stressful life events, job adversity, and workplace support. In categorical analyses, 86% of the teachers identified as burned out met criteria for a provisional diagnosis of depression. Exploratory analyses revealed a link between burnout and anxiety. Conclusions: This study provides evidence that past research has underestimated burnout–depression overlap. The state of burnout is likely to be a form of depression. Given the magnitude of burnout–depression overlap, treatments for depression may help workers identified as burned out. Copyright 2015 Wiley Periodicals, Inc. J. Clin. Psychol. 72:22–37, 2016

Adapting brief CBT-I for depressed adolescents: a case illustration of the sleeping better program

Disturbed sleep is a common symptom of depression in adolescents, but this symptom is not often targeted in psychological therapies for depression. Although the causal relationship between sleep and depression is unclear, there is increasing evidence that in adults, Cognitive Behavioral Therapy for Insomnia (CBT-I) improves sleep problems and reduces symptoms of depression; however, there has been little investigation of using this approach with adolescents. This article describes the adaptation of brief CBT-I for adolescents with depression. A single case study is reported to illustrate the use of the Sleeping Better program. Adaptations for adolescents include increased emphasis on engagement of the young person and the inclusion of parents in treatment. The treatment program was acceptable to the adolescent and parent, and treatment outcome, as indicated by sleep diaries and standardized measures of depression and anxiety, was positive. Further evaluation of the Sleeping Better program is needed to establish if it is an effective low-intensity intervention for sleep problems in adolescents who have depression or anxiety

The European Insomnia Guideline : An update on the diagnosis and treatment of insomnia 2023

Publisher Copyright: © 2023 The Authors. Journal of Sleep Research published by John Wiley & Sons Ltd on behalf of European Sleep Research Society.Progress in the field of insomnia since 2017 necessitated this update of the European Insomnia Guideline. Recommendations for the diagnostic procedure for insomnia and its comorbidities are: clinical interview (encompassing sleep and medical history); the use of sleep questionnaires and diaries (and physical examination and additional measures where indicated) (A). Actigraphy is not recommended for the routine evaluation of insomnia (C), but may be useful for differential-diagnostic purposes (A). Polysomnography should be used to evaluate other sleep disorders if suspected (i.e. periodic limb movement disorder, sleep-related breathing disorders, etc.), treatment-resistant insomnia (A) and for other indications (B). Cognitive-behavioural therapy for insomnia is recommended as the first-line treatment for chronic insomnia in adults of any age (including patients with comorbidities), either applied in-person or digitally (A). When cognitive-behavioural therapy for insomnia is not sufficiently effective, a pharmacological intervention can be offered (A). Benzodiazepines (A), benzodiazepine receptor agonists (A), daridorexant (A) and low-dose sedating antidepressants (B) can be used for the short-term treatment of insomnia (≤ 4 weeks). Longer-term treatment with these substances may be initiated in some cases, considering advantages and disadvantages (B). Orexin receptor antagonists can be used for periods of up to 3 months or longer in some cases (A). Prolonged-release melatonin can be used for up to 3 months in patients ≥ 55 years (B). Antihistaminergic drugs, antipsychotics, fast-release melatonin, ramelteon and phytotherapeutics are not recommended for insomnia treatment (A). Light therapy and exercise interventions may be useful as adjunct therapies to cognitive-behavioural therapy for insomnia (B).Peer reviewe
