Published Date
September 3, 2026

Researchers at the University of Lille are seeking participants for a study examining the psychological experiences of people exposed to group psychological abuse or cultic involvement. By comparing people who have and have not had these experiences, the study aims to better understand their potential psychological impact, including factors associated with difficulties, resilience, and recovery after leaving a group.About the study

Title: Research on psychological impacts following exposure to group psychological abuse

Lead researcher: Victor Laurent

Research team:

  • Dr. Sylvain Delouvée, Postdoctoral Supervisor
  • Dr. Thierry Kosinski, Postdoctoral Supervisor
  • Dr. C. Creupelandt, Research Collaborator
  • M. Onfray, Patient Partner involved in the research

Institution: University of Lille, France

 

Research ethics and participant information

The researchers have provided documentation relating to ethics approval and informed consent.

Because the study also recruits a control group of individuals who have not been exposed to group psychological abuse, the informed consent form is intentionally broad and describes the research as concerning psychological experiences following past group membership. When contacting organizations that may reach people who have experienced group psychological abuse, the researchers specify this particular focus of the study.

What participation involves

Participation involves completing an online survey. The researchers aim to recruit:

  • A minimum of 175 participants who have been exposed to psychological abuse within a group, as assessed using the Psychological Abuse Experienced in Groups Scale (PAEGS; Saldaña et al., 2017)
  • An equal number of participants who have not been exposed to group psychological abuse

The survey is available in English and French.

Why participate

By participating, individuals can contribute to research seeking to improve understanding of the psychological experiences associated with group psychological abuse and cultic involvement.

The researchers hope the findings will contribute to:

  • Better understanding of factors associated with psychological difficulties and resilience
  • Identifying areas of need and factors that may support recovery
  • Informing future research and the development of more appropriate support for affected individuals

Who is eligible

The study is recruiting both:

  • Individuals who have experienced psychological abuse within a group
  • Individuals who have not experienced group psychological abuse, as part of the comparison group

Research background and impact

The researchers plan to disseminate the findings through scientific publications, oral presentations, and presentations to relevant organizations and professionals. Where possible, they will also engage with researchers, clinicians, and other relevant professionals to assess the practical, clinical, and scientific implications of the findings.
