Psychobiology of Stress
The research group “Psychobiology of Stress” focuses on the biological underpinnings of mental disorders related to the stress hormone system. Among others, methods for assessing long-term stress hormone concentrations (hair steroid analyses), stress hormone analyses in saliva, and experimental stress induction paradigms (Trier Social Stress Test) are used. In addition to investigating the role of stress-associated biomarkers in the development and maintenance of mental illnesses (e.g. post-traumatic stress disorder, generalized anxiety disorder), their potential as predictors and correlates of successful psychotherapy is being studied. The research results thus create an important basis for the future improvement of personalized treatment options.

Susann Schmiedgen (née Steudte) completed her PhD at the Chair of Biopsychology in Dresden after studying psychology. She then spent her post-doctoral period in Dresden as well as at Oxford University in England. In recent years, she has been intensively involved in the development of hair steroid analysis for the detection of long-term stress hormones and its application in the study of the biological underpinnings of mental disorders. Her main scientific interest is the role of cognitive and endocrine markers in the development and maintenance of trauma-related psychopathology and as predictors and correlates of symptom improvement after psychotherapy. Her research activities have been awarded, among others, the Commerzbank Prize (2014) and the Research award from the Falk von Reichenbach Foundation of the German Society for Psychotraumatology (2018).
Studies
The main study DREAM:
Launched in June 2017, the multi-method Dresden Study on Parenting, Work, and Mental Health (DREAM) explores the prospective relationship between parenthood, work, and health of the whole family and includes a total of N = 3,861 (expectant) parents. The study design provides a unique opportunity to explore longitudinal biological pathways underlying the effects of parental stress around pregnancy and birth on child development.
Biological sub-study DREAMHAIR
In our sub-study DREAMHAIR, we are interested in how the body’s stress hormone system responds to the specific challenges during pregnancy and after birth. Further, we are interested in the consequences this may have for the well-being of all family members. Hair analysis represents an innovative method to measure long‑term stress hormone release (e.g., cortisol). Cortisol is an essential endogenous stress hormone enabling us to adapt to stressful situations. Hair retains cortisol, which only grows out slowly. Initial studies indicate this process already takes place in the womb. In other words, maternal stress load will probably be reflected in the baby’s hair cortisol even before the baby is exposed to external influences.
The aim of DREAMHAIR is to investigate the concentration of various stress hormones in the hair of mother, father, and child at five measurement points up to 4.5 years postpartum and examine which external factors exert an influence on this concentration. In the future, this could enable us to objectify family stress factors and derive preventive measures that are specifically adapted to the needs of young families.
DREAMHAIR is a project in cooperation with:
- Prof. Dr. Susan Garthus-Niegel (Research area Public Mental Health at the Institute and Policlinic for Occupational and Social Medicine at the TU Dresden)
- Prof. Dr. Clemens Kirschbaum (Professor of Biopsychology, Faculty of Psychology at TU Dresden)
Biological sub-study DREAMEPI
In our substudy DREAMEPI we are interested in the child’s epigenome. The entire “blueprint” for our body is stored in our genes (at the level of our genetic material, the so-called DNA). Whether and in what form this information is read depends, among other things, on so-called epigenetic mechanisms, which can silence or activate genes. Previous research shows that several environmental influences during the time in the womb and shortly after birth can impact the offspring’s epigenome. For this reason, the substudy DREAMEPI investigates the extent to which parental general and work-related stress as well as trauma exposure before and after birth is associated with childhood epigenetic changes and to what extent these changes influence the child’s health.
For this purpose, parents from DREAM and their 4.5-year-old children take part in a test in our study laboratory. The collection of children’s saliva samples enables the detection of changes in the epigenome. Furthermore, saliva and hair samples are taken to determine stress-associated biomarkers (e.g., cortisol) and questionnaires are completed to collect information regarding psychological symptoms and general health.
The aim of the DFG-funded DREAMEPI substudy is to better understand the molecular pathways underlying the fetal origins of health and disease, which could contribute to the development of evidence-based prevention strategies in the long-term.

Wochenkrippen study
Psychological and biological long-term consequences of the Wochenkrippen care in the former German Democratic Republic in adulthood
In the Wochenkrippen of the former German Democratic Republic (GDR), infants and toddlers were cared for continuously from Monday to Friday, sometimes until Saturday, and spent only the weekend with their family. It is estimated that between 1949 and 1989 several hundred thousand infants were placed in such a weekday nursery care up to the age of three years. Until now, there have been few systematic studies on the current health of individuals who received Wochenkrippen care. In a collaborative project, we aim to carefully examine aspects of mental health, attachment-related characteristics and the regulation of the stress hormone system of former Wochenkrippe children.
In addition to participants who were cared for in a Wochenkrippe, we also include individuals who were born and raised in the former GDR, but attended a Tageskrippe (i.e., receiving care on a daily basis) or were cared for by parents or close family members during the first three years of life.
In an online survey, questionnaires are used to assess mental health, attachment-related characteristics and lifetime traumatic experiences. This is complemented by the analysis of stress hormone concentrations in hair (mainly cortisol) to investigate whether the care experiences within the first three years of life affect long-term stress hormone regulation. In a second part of the study, a sub-sample is asked in more detail about their mental health in a diagnostic interview.
The research results will be made available to the public and will be incorporated into counseling and treatment services for former Wochenkrippen children.
