One Hour of Somatic Experiencing Increases Psychological Safety in Child Maltreatment Survivors
- Two experiments testing a brief (one-hour) Somatic Experiencing intervention in adults with varying degrees of child maltreatment history
- The body-oriented intervention increased psychological safety and reduced disrupted body boundaries — two core features of trauma presentations
- Effects were observed regardless of severity of childhood maltreatment — the intervention worked for mild and severe histories alike
- The intervention focused on interoceptive awareness — helping participants attend to and regulate internal bodily sensations
Somatic Experiencing has been practiced for decades but studied too little. This European Journal of Psychotraumatology study provides something rare: experimental evidence that a brief, body-oriented intervention produces measurable changes in psychological safety — the foundation without which trauma processing cannot begin.
What the study tested
The researchers ran two experiments with adults across a spectrum of child maltreatment experiences. The intervention was a single one-hour Somatic Experiencing session — not a full course of treatment, but a focused body-oriented exercise centred on interoceptive awareness: noticing internal bodily sensations, grounding through physical awareness, and developing a felt sense of safety.
The outcome measures targeted two constructs: psychological safety (feeling safe in one's body and environment) and disrupted body boundaries (the sense that the boundary between self and environment is unstable or permeable — a common but underrecognised feature of complex trauma).
Why felt safety matters
Peter Levine's "felt safety" concept has been central to Somatic Experiencing theory but has lacked experimental validation. This study operationalises it: after a single session, participants reported measurably increased psychological safety and reduced body boundary disruption.
For trauma therapists, this validates what body-oriented practitioners have observed clinically: some patients cannot access trauma memories through top-down verbal processing because their bodies do not feel safe enough to allow it. Building felt safety through somatic work creates the conditions for subsequent trauma processing.
For your practice
If you work with trauma patients who struggle with dissociation, somatic flashbacks, or difficulty engaging in exposure-based work, this study provides evidence for what you may already do intuitively: start with the body. One hour of structured somatic work can measurably shift the felt sense of safety.
A single hour of Somatic Experiencing increased psychological safety and reduced body boundary disruption in adults with child maltreatment histories — the first experimental evidence for Peter Levine's "felt safety" concept.
