The results, which are published in the highly ranked journal JAMA Dermatology, can lead to improved access to treatment for patients and reduce the burden on healthcare.

The findings are published online in the journal Biological Psychiatry.

Traumatic experiences such as assault or a road accident can give rise to nightmares, flashbacks and other mental reactions, and accessible therapy is needed to prevent exacerbation of the problems. Researchers at Karolinska Institutet have now completed what could be the largest evaluation to date of internet-delivered trauma-focused CBT (iCBT-T) for people who have recently experienced trauma. The study, which is published in Psychological Medicine, shows promising results.

Both humans and other animals learn quickly about dangers in their environment by observing the behavior of other individuals. Researchers at Karolinska Institutet now show that both rats and humans can use such social information to reactivate memories about threats that have been previously acquired through their own experiences.

Early intervention for disruptive behaviour disorders in children reduces the risk of antisocial development and psychiatric problems later in life. Parental training and child CBT are two interventions about which more needs to be known concerning the effects on disruptive behaviour disorders. According to a new doctoral thesis from Karolinska Institutet, both have a positive effect on such disorders, where severity should determine the choice of treatment.

Sweden was the first country in the world to introduce open-identity sperm donation, whereby adult children are entitled to obtain information about their donors. Researchers at Karolinska Institutet have now explored how such contacts and relations affect the parents of these young men and women. The study, which is published in Human Reproduction, shows that mothers often find it easier to accept the new situation.

Social anxiety disorder can cause considerable suffering in children and adolescents and, for many with the disorder, access to effective treatment is limited. Researchers at Centre for Psychiatry Research at Karolinska Institutet and Region Stockholm have now shown that internet-delivered cognitive behavioural therapy is an efficacious and cost-effective treatment option. The study is published in the journal JAMA Psychiatry.

Obsessive-compulsive disorder (OCD) in children and adolescents is associated with impaired education and worse general health later in life. Access to specialist treatment is often limited.

The study, published in the prestigious journal JAMA, can help make treatment for OCD more widely accessible.

Depressed children and teenagers have an increased risk of suffering from premature death and a wide range of illnesses later in life. That is according to a large observational study by researchers at Karolinska Institutet in Sweden. The findings highlight the need to look for other potential diseases following childhood or adolescent depression. Other psychiatric conditions, such as anxiety and substance misuse, can explain part of the association. The study is published in JAMA Psychiatry.

It is a known fact that sexual minorities are at a higher risk of developing poor mental health, when compared to heterosexuals. The stigma that sexual minorities face has been regarded as potentially the primary cause of this. A new thesis from Karolinska Institutet offers an insight into how stigma-related factors may work in a broader socio-ecological system, considering the complex interaction between structural, interpersonal and individual factors.

Worry about COVID-19 dominates some people’s lives in a way that has an impact on their health. A group of researchers at Karolinska Institutet in Sweden has developed a digital CBT programme that significantly reduced the participants’ unhelpful worry about the pandemic. The study is published in Psychotherapy and Psychosomatics and the programme is available through 1177 Vårdguiden.

Researchers at Karolinska Institutet have compared two ways of delivering cognitive behavioral therapy to treat people with health anxiety, a condition that may increase in the wake of COVID-19. Out of about 200 study participants, half received Internet-CBT and half received conventional face-to-face CBT. The results, published in JAMA Psychiatry, show that Internet-delivered treatment had comparable effects, and may serve as an alternative in helping people who are worried about their health.

An international network of researchers in 10 countries are to study the effectiveness of homeschooling during the ongoing COVID-19 pandemic. The gathering of data via online surveys in the various languages is being led by researchers at Karolinska Institutet.

These are the findings of a population-based study from Karolinska Institutet in Sweden published in the journal Psychological Medicine.

A sleepless night not only leaves us fatigued and distracted, it also makes us interpret things more negatively and makes us more likely to lose our temper.

This according to a new doctoral thesis from Karolinska Institutet that takes a neuroimaging approach to sleep loss.

Learning what is dangerous by watching a video or being told (known as social learning) has just as strong an effect on our decision-making as first-hand experience of danger, researchers at Karolinska Institutet in Sweden report. The results of the study, which is published in the journal PNAS (Proceedings of the National Academy of Sciences), can help to explain why we take irrational decisions.
