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…

Adolescents who were more popular among their classmates in junior school are often the ones who are more inclined to share things fairly with others. During this sharing process, 'social' areas of the brain are more strongly activated than in adolescents who are less popular. This is the finding of…

Behavioral and neural mechanisms underlying self-concept development in relation to educational decision-making in adolescence

The main aim of this dissertation was to provide insight into possible subtle forms of bias in youth socialization by various socializing agents in the Netherlands, and exploring new ways to document bias. Additionally, it addresses the importance of using sound statistical methods for calculating effect…

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.…

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.

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…

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…

Parents often see that when their sweet, socially-minded children become adolescents they change into selfish 'hotel guests' who think only of themselves. But adolescents become increasingly better at weighing up one another's interests. This discovery has been made by development psychologist Rosa…

The roles of shame, guilt and social access in adolescent aggression

ADHD&me is a new cognitive-behavioural therapeutic intervention for young adults (16–25 years old) with ADHD, specifically aimed at improving self-esteem. In this study, we are conducting a Randomized Controlled Trial (RCT) to examine whether this intervention improves self-esteem and whether related…

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

When and how does social anxiety develop? How can it go astray in some adolescents? How can we help troubled young people to attend school regularly and return to a normal developmental pathway?

What are the developmental pathways to social anxiety (disorder), the causal processes and maintaining factors? How do these factors interact in the development of social anxiety disorder? How can this knowledge be used to design and implement effective preventive intervention programs for youth?

Some people are more sensitive to depression than others. But why is that the case? Clinical psychologist Niki Antypa studied how vulnerability to depression is influenced by cognition. She also found a first careful indication that a treatment with omega-3 fatty acids might provide a solution.

During adolescence, some young people have stable best-friend relationships, while others change best friends frequently. Developmental psychologist Lisa Schreuders has studied the brains of young adolescents: ‘It seems that friendships in your early years can have consequences for your friendships…

There is a link in adolescents between brain connections and impulsiveness. Leiden researchers have discovered that these connections also predict which adolescents will make more impulsive choices two years further on.

Welcome to the Social Anxiety and Specific Phobia (SASP) Research Group!

Young people are particularly susceptible to misleading information on social media. Yet insights from developmental psychology show that they also have unique strengths to build resilience. In new research led by developmental psychologist Ili Ma, scientists, schools, parents and policy makers are…

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.

Developmental considerations in the design and delivery of cognitive-behavioural therapy for adolescent school refusal

Medical psychologist Willeke Kitselaar developed a model that helps identify patients with persistent somatic symptoms earlier, based on an extensive large medical database. ‘I advise GPs to ask patients to fill in a questionnaire about both physical and mental symptoms at an earlier stage.’ PhD defence…

The overarching aim of this theme is to increase our understanding of the mechanisms underlying altered cognitive, affective, and social behavior in relation to mental health problems.

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.

The brains of adolescents react more responsively to receiving rewards. This can lead to risky behaviour, but, according to Leiden University research, it also has a positive function: it makes learning easier. Publication in Nature Communications.

What happens in young people's brains when they win money for someone else? Psychologist Elisabeth Schreuders has shown that the brain responds differently according to the type of friendship and that the response is strongest with stable relationships later in adolescence. PhD defence on 6 March.

Do general practitioners recognize children with or at risk of problematic anxiety and is there a pattern that might help differentiate those with and without anxiety disorders in general practice?

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 impact does growing up in a musical environment or during the COVID-19 pandemic have on the brain development of teenagers? This was the focus of psychologist Lina van Drunen’s PhD research, which studied hundreds of twins. Her findings reveal that practising music slows brain development, presenting…

Why does social anxiety increase in adolescence and how does it grow out of control in some adolescents?

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.

Under 18, no alcohol. In spite of this slogan, adolescents still have access to alcohol. But how harmful is that one beer for the adolescent brain? Research, including in Leiden, may provide the answer.

The main focus of our research programme is on adolescence, a key transitional period in human development. The programme puts emphasis on combined experimental behavioural and neural analysis of normative transitions and deviations in adolescent development.

The section Developmental and Educational Psychology consists of more than 45 people, who are mainly involved in education and research.
