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?

Somatic symptoms, such as pain, itch, and fatigue have been shown to have a bidirectional relationship with mental symptoms. Although acute somatic symptoms serve some adaptive properties, chronic symptoms can instead lead to interference in daily activities and lower quality of life.

The STAP study examines the cost-effectiveness of Written Exposure Therapy (WET) for post-traumatic stress disorder (PTSD) symptoms in primary care settings.

Veel vrouwen in een opvanghuis kampen met een posttraumatische stressstoornis (PTSS). Deze PTSS-klachten herkennen en direct behandelen biedt volgens het Leids Universitair Behandel en Expertise Centrum (LUBEC) de meeste kans op succes. Daarom werkt LUBEC per 1 september samen met vrouwenopvangorganisatie…

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.

In the MS Cognitietour, psychologists and neuroscientists from Leiden University discuss the latest scientific knowledge with MS patients and their loved ones. This leads to insights: 'One lady told how much stress she felt from all those caregivers around her bed.'

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…

Scientists in Leiden are looking for signals in blood samples to predict whether patients will develop serious COVID-19 symptoms or not. Based on that knowledge, they will be able to propose targeted therapies to prevent serious symptoms. They hope to come up with the first results within the week.

Our mission is to improve the description, prediction, understanding and the prevention and treatment of mood disorders, including unipolar and bipolar depression, as well as suicidal thoughts, feelings, and behaviors. To tackle this ambitious mission, we focus on several research streams.

Can positive peer feedback break the cycle of negative self-relevant cognitive processes and reduce self-reported anxiety in early adolescents?

Our vision of stress is starting to change fundamentally. We can suffer stress without even being aware of it, while sleeping as wall as during the day. Professor of Psychology Jos Brosschot will discuss this phenomenon in his inaugural lecture on 2 December.

This longitudinal study is focused on neurodevelopmental problems in young children with XXY, XXX and XYY, aged 1 to 6 years.

In the last decades, activity-based protein profiling (ABPP) has emerged as a powerful chemical tool that may aid the ever-challenging drug discovery process.

Elk jaar organiseert het LIBC in samenwerking met de gemeente Leiden een Publieksdag over hersenonderzoek.

Cognitive decline and anxiety in Parkinson’s disease are often only recognised at a late stage, in spite of their great impact. Research by Marit Ruitenberg focuses on new tests and methods to show up these symptoms earlier and make them more specific.

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

The key question addressed in this family study is whether the psychophysiological and neurocognitive abnormalities often reported in SAD patients are heritable and can thus be found in family members of SAD patients as well. Determination of heritability of these deficiencies is essential for endophenotyping.…

How do parents communicate anxiety to their child via body language and words? Psychologist Cosima Nimphy studied this question for her PhD research. Experiments show that children of anxious parents are not more sensitive to their parents’ signs of anxiety.

Members of our research team give different types of presentations and lectures.

Not for scientist Eiko Fried. 'There is a real chance we can prevent some mental health problems before they occur.' Want to participate…

The ability to collect and interpret huge quantities of data has become indispensable to society and academia. Leiden University is a knowledge and expertise centre for data science that places the emphasis on interdisciplinary collaboration and innovation.

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?'

Within this theme, we study diseases ranging from rare genetic disorders to cancer and infectious diseases. We make use of a wide variety of model systems and pursue diverse…

Programs that aim to reduce symptoms of social anxiety in children generally include multiple components, such as exposure and cognitive restructuring. It is unknown if separate components yield positive intervention effects in children or whether a combination of components is required.

Our mission is to recognise and treat stress and anxiety in children as early as possible, by connecting scientific research, clinical practice and education.

It may seem as though adolescents do as they please, but they are more sensitive to their parents’ opinions than they would appear. The adolescent brain reacts strongly to parental criticism or praise. These are the results of a study by an interdisciplinary research group of psychologists and neuroscientists…
