Anette Kjellgren

Anette Kjellgren is a Professor in Psychology at Karlstad University, Sweden. Her research focuses on altered states of consciousness, psychedelic substances, sensory deprivation therapy, and novel psychoactive substances (NPS). She has conducted extensive studies on flotation-REST (Restricted Environmental Stimulation Technique) as a therapeutic intervention for anxiety, insomnia, and burnout. Her work bridges clinical psychology, pharmacology, and digital health, exploring both traditional and emerging treatment modalities.

Key research areas include:

• Psychedelic microdosing effects
• Substance use patterns and motivations
• Flotation therapy for mental health
• Online drug community dynamics

Her studies analyze drug-related behaviors through mixed-methods approaches, combining qualitative analysis of user experiences with quantitative clinical trials. Recent work addresses barriers to help-seeking in drug emergencies and the therapeutic potential of sensory isolation techniques.

Publications span over 20 years, with methodological innovations like the Experienced Deviation from Normal state (EDN) scale for measuring altered consciousness. Collaborations include interdisciplinary teams examining yoga, meditation, and Ayahuasca experiences.
