Overview

Niklas Långström is affiliated with the Karolinska Institute in Sweden and has a research profile concentrated in the fields of psychology and social sciences. Their body of work primarily spans clinical psychology, sociology and political science, general health professions, genetics, and experimental and cognitive psychology.

The research topics covered include:

  • Psychopathy, forensic psychiatry, sexual offending
  • Criminal justice and corrections analysis
  • Child abuse and trauma
  • Crime patterns and interventions
  • Healthcare decision-making and restraints
  • Child and adolescent psychosocial and emotional development
  • Evolutionary psychology and human behavior

Several frequent co-authors have collaborated with Niklas Långström, including Seena Fazel, Alexander Rozental, Paul Lichtenstein, Rongqin Yu, and Abdel Abdellaoui. These collaborations are reflected in multiple publications throughout Långström's career.

Publication venues where their work frequently appears are:

Among recent papers, notable examples include:

  • "An Updated Systematic Review and Meta-regression Analysis: Mental Disorders Among Adolescents in Juvenile Detention and Correctional Facilities" (2020) in the Journal of the American Academy of Child & Adolescent Psychiatry
  • "Genomic evidence consistent with antagonistic pleiotropy may help explain the evolutionary maintenance of same-sex sexual behaviour in humans" (2021) in Nature Human Behaviour
  • "Effects of internet-delivered cognitive behavioral therapy on use of child sexual abuse material: A randomized placebo-controlled trial on the Darknet" (2022) in Internet Interventions

Related Online Degrees & Career Pathways

Online psychology degrees open doors to a variety of career paths, including counseling, social work, and therapy. Many students interested in therapy careers—such as marriage and family therapy (MFT)—often pursue specialized graduate programs to meet licensing requirements. With flexible online options, it’s now possible to gain the necessary knowledge and credentials while balancing work and other commitments.

Each state has unique educational and licensure rules. For example, those wanting to learn how to become a marriage and family therapist in Houston must meet Texas-specific requirements, while Huntsville mft education requirements may involve local criteria and program accreditation. If you’re exploring therapy careers in the Midwest, it’s important to research Indianapolis mft education requirements, as these may differ from those on the West Coast, such as the Irvine mft education requirements.

Careful planning is essential when choosing an online program, especially if you aim for a specialized license. Make sure to select accredited programs that align with your state’s regulations for your preferred career pathway.
