What are the circadian disturbances underlying depression vulnerability? How are they related to mood, cognition and sleep ?

Optimization, mechanisms of action and predictors of the outcome of light therapy in depression: A multicenter randomized trial

The Leiden Index of Depression Sensitivity (LEIDS) measures cognitive reactivity (CR) to sadness, an aspect of cognitive vulnerability to depression, conceptually similar to rumination.

How do genetic and environmental factors make us vulnerable to depression?

To investigate the effectiveness of an online self-help programme for people with HIV and depressive symptoms.

My ERC Starting Grant, funded with €1.5 million for 5 years as part of the Horizon 2020 research and innovation program, is focused on building the early warning system WARN-D to reliably forecast depression in young adults before it occurs. Why depression, and why prediction?

I want to understand the overlap between physical health, mental health, and healthy aging and whether/how stress (behaviorally and biologically) may tie these concepts together.

We found that, next to the effectiveness of the intervention, it’s also very likely that the intervention is cost-effective compared to attention only.

What is the effectiveness of (booklet or online) self-help programmes for people with somatic stressors and depressive symptoms? What works best for whom? How to improve motivation and adherence?

Depression has traditionally been linked to increased inflammation. Innovative research by psychologist Eiko Fried refutes this popular assumption. He shows that specific depression symptoms such as sleeping problems explain this relationship. Publication in Psychological Medicine .

Evidence that the right diet can prevent or alleviate depression is weak. In literature reviews on the subject, the authors often reach strong conclusions, nonetheless. This is what Florian Thomas-Odenthal, a master’s student in Psychology at Leiden University, discovered in his thesis research. Publication…

Teens with depression appear to be more sensitive to criticism from their parents than their healthy peers are.

Many primary school children suffer from anxiety and their numbers are increasing. Psychologists from the Knowledge Center Anxiety & Stress (KAS) are developing and researching preventive training.

What causes depression in a child and how can they get over it? Leiden Professor of Psychology Bernet Elzinga and behavioural scientist Carine Kielstra recently hosted a webinar on the subject of depression in teenagers. The level of interest was overwhelming.

With a starting grant of the European Research Council (ERC) for promising young researchers, Eiko Fried aims to develop a personalised early warning system, that will reliably forecast depression before it occurs. Fried (Clinical Psychology) talks about this WARN-D, promising to radically transform…

Eye contact between parents and children improves their mood and increases feelings of connectedness on both sides; but not in the case of depressed adolescents, Mirjam Wever discovered. Where the parent-child bond has been disrupted, it can be strengthened not only with therapy for the child but also…

The aim of this project is to investigate the (cost)effectiveness of two innovative forms of trauma-focused therapy for patients with childhood abuse related PTSD. The ultimate goal is to improve quality of care and contribute to treatment innovation for this severely ill target population.

Adolescents with good friendships experience fewer anxiety and depression symptoms, PhD student Iris Koele discovered in her research on high school students' social relationships. 'As a psychologist, I include friends in the treatment plan: who do you call when things are not going well?'

People who have taken antibiotics in the past three months pay more attention to negative facial expressions, according to research by postdoc Katerina Johnson and assistant professor Laura Steenbergen. This may explain how antibiotics increase the risk of developing depression.

Predictors of work functioning in persons with multiple sclerosis

Imagine how much time, money and discomfort it would save: a personalised treatment for each individual patient. Precision medicine like this is coming ever closer, thanks in part to Elise Dusseldorp’s algorithms. They retrieve a wealth of information from research data.

People already diagnosed with a mental disorder before the COVID-19 pandemic did not show a disproportionate increase in symptoms afterwards. This is one result from the first systematic review of longitudinal studies following their study population from before to during the first eighteen months of…

CERQ is a questionnaire measuring cognitive coping strategies developed by Dr. Nadia Garnefski and Dr. Vivian Kraaij.

Positive friendships are characterised by understanding mutual wishes and intentions, respect for each other’s boundaries and pro-social behaviour. Qualities that might be more challenging for autistic adolescents.

In a longitudinal study, Eichengreen and colleagues explored how the certain aspects of emotional intelligence impact the development of adolescents’ mental health, thus identifying potential warning signs and targets for intervention programs. Despite a higher risk for mental health issues and lesser…

Is blended care a feasible and effective treatment method for social anxiety in adolescence?

Clinical psychology is a discipline concerned with the application of psychological science to the assessment and treatment of mental disorders.

Primary Objective: The primary aim of the proposed RCT is to evaluate whether LF-TLP in blended form as an indicated prevention for anxiety complaints is more (cost-) effective than TAU according to the NHG guideline Anxiety. We hypothesize that in comparison to TAU, LF-TLP will result in a significantly…
