Effectiveness of a guided digital self-help intervention to improve sleep and the biological clock in university students - Study protocol for a randomized controlled trial.

Background: Sleep problems occur in many university students which affects their mental health and daily functioning. Cognitive behavioural therapy for insomnia (CBT-I) has been proven effective in adults but research in university students, who struggle to maintain a 24-hour rhythm, is still limited. We hypothesize that a guided digital CBT-I intervention, enriched with components on the biological clock () will be effective in reducing insomnia severity and improving mental health outcomes for students with sleep problems.

The effectiveness of unguided self-help psychological interventions for obsessive-compulsive disorder: A meta-analysis of randomized controlled trials.

Background: Evidence-based psychological interventions exist for individuals with obsessive-compulsive disorder (OCD), but many individuals with OCD are unable to access them because of barriers, such as geographical isolation, treatment cost, and stigma etc. Unguided self-help psychological intervention has emerged as a potential solution to this problem. However, there is limited research on its overall effectiveness.

User profile of an online cognitive behavioral therapy self-help platform in Turkey.

Online mental health self-help services are of societal importance and increasingly popular. Therefore, we have developed an online platform offering free self-help to the Turkish public with modules based on Cognitive Behavioral Therapy (CBT) targeting depression, anxiety, and stress respectively. The main purpose of this study is to describe the user profile of this platform.

Effectiveness of a guided internet-based intervention for procrastination among university students - A randomized controlled trial study protocol.

Unlabelled: is a widespread problem that is highly prevalent among the young adult population and is associated with several negative consequences. However, current evidence on the effectiveness of e-health interventions for procrastination either lack a comparison to an inactive control, do not include a student population or are of poor quality. This protocol describes the design of a trial that will overcome these limitations and examine the effectiveness of a guided internet-based intervention () to reduce problematic procrastinating behaviors in college students compared to a waitlist control.

Effects of psychological treatment for depression among people not actively seeking help: a meta-analysis.

Although psychological treatments have been found to be effective for depression in adults, many individuals with depression do not actively seek help. It is currently unclear whether psychological treatments are effective among those not actively seeking help. Besides, little is known about the proportion of patients who completed a screening questionnaire who end up in a clinical trial.

Psychological risk factors and the course of depression and anxiety disorders: A review of 15 years NESDA research.

Background: The Netherlands Study of Depression and Anxiety (NESDA; N=2981) is an ongoing longitudinal, multi-site, naturalistic, cohort study examining the etiology, course, and consequences of depression and anxiety. In this article we synthesize and evaluate fifteen years of NESDA research on prominent psychological risk factors for the onset, persistence, recurrence, and comorbidity of affective disorders.

Methods: A narrative review of 62 NESDA articles examining the specificity and predictive value of neuroticism, behavioral inhibition, repetitive negative thinking, experiential avoidance, cognitive reactivity, locus of control, (implicit) self-esteem, (implicit) disorder-specific self-associations, and attentional bias for the course of affective disorders.

Psychological interventions to prevent the onset of depressive disorders: A meta-analysis of randomized controlled trials.

Purpose: Depressive disorders are common and have a considerable impact on patients and societies. Several treatments are available, but their effects are modest and reduce the burden only to a limited extent. Preventing the onset of depressive disorders may be one option to further reduce the global disease burden.

Temporal stability of symptoms of affective disorders, cognitive vulnerability and personality over time.

Background: Signs and symptoms of psychopathology can be chronic but are generally regarded as less stable over time than markers of cognitive vulnerability and personality. Some findings suggest that these differences in temporal stability are modest in size but a rigorous examination across concepts is lacking. The current study investigated the temporal stability of affective symptoms, cognitive vulnerability markers and personality traits at various assessments over nine years.

The predictive specificity of psychological vulnerability markers for the course of affective disorders.

High scores on markers of psychological vulnerability have been associated with a worse course of affective disorders. However, little is known about the specificity of those associations in predicting the course of different depressive and anxiety disorders. We examined the impact of psychological vulnerability on the short- and long-term course of depressive and anxiety disorders.

The predictive value of Approach and Avoidance tendencies on the onset and course of depression and anxiety disorders.

Background: Trait and automatic approach-avoidance (AA) tendencies are central concepts in research on affective disorders. We longitudinally examined the associations of trait and automatic AA tendencies with the risk of onset and chronicity of anxiety and depressive disorders.

Methods: Participants were subdivided into those with (n = 766) versus without (n = 1,636) a current anxiety or depression diagnosis at baseline.

Approach and avoidance tendencies in depression and anxiety disorders.

Anxiety is linked to increased avoidance and inhibition, whereas depression is linked to decreased approach and diminished behavioral activation. Although these notions are widely recognized, systematic investigation of approach-avoidance tendencies is lacking across these diagnostic groups. Participants (mean age = 45.

Cognitive vulnerability differentially predicts symptom dimensions of depression.

Background: We examined the association of cognitive vulnerability to depression with changes in homogeneous measures of depressive symptoms.

Methods: Baseline and 1-year follow-up data were obtained from 2981 participants of the Netherlands study of depression and anxiety. Multivariate regression analyses were carried out on cognitive reactivity, locus of control and implicit and explicit self-depressive associations in combination with negative life events.
