Participant experiences of therapeutic touch in psilocybin-assisted therapy

In a longitudinal qualitative study of 18 participants in a psilocybin-assisted therapy trial for generalized anxiety disorder, most participants valued therapeutic touch—particularly after first-hand experience during dosing sessions—reporting it fostered connection, helped manage acute psychedelic intensity and was sometimes experienced as directly therapeutic. Responses were diverse, however, and participants emphasised the need for a strong therapeutic relationship, individualised use within comprehensive consent, and further research on safety and therapist training.

Abstract

Introduction

Although commonly used in psychedelic-assisted therapy, the role of therapeutic touch remains loosely defined and ethically sensitive. Gaining insight into how participants experience and interpret touch during psychedelic sessions is essential for informing safe and effective clinical practice.

Methods

Participants were sampled from a large randomized clinical trial of psilocybin-assisted therapy that permitted protocol-defined supportive touch. Longitudinal qualitative data (39 semi-structured interviews) were analyzed from n = 18 participants. Interviews covered expectations, experiences, and reflections on the use of touch during acute psychedelic states, before and after dosing. Thematic analysis was used to identify major themes.

Results

Participants expressed varied preferences and responses to therapeutic touch. Most valued its availability, particularly after firsthand experience, describing its capacity to foster emotional connection, provide grounding during intense affective states, and modulate the depth of psychedelic experience. Several reported perceiving therapeutic benefit directly attributable to touch. Acceptability was consistently linked to the quality of the therapeutic relationship and robust consent processes. Some participants also identified potential for discomfort or distraction, underscoring the need for sensitivity to individual history and context.

Conclusions

Therapeutic touch may support emotional safety and affect regulation during acute psychedelic states. Findings highlight the importance of explicit preparation, consent, and attunement when incorporating touch into psychedelic therapy. Further research should inform therapist training, individualized consent frameworks, and safety protocols to guide ethical and effective use in clinical practice.

Research Summary of 'Participant experiences of therapeutic touch in psilocybin-assisted therapy'

Introduction

Psychedelic-assisted therapy (PAT) is expanding rapidly as a clinical approach, including recent regulatory changes that have increased authorised clinical access to psilocybin and MDMA in some jurisdictions. The paper situates therapeutic touch as a common but under-researched element of contemporary PAT protocols. The authors note that psychedelics create transient, intense changes in conscious awareness that can impair verbal communication and that non-verbal supports such as touch are therefore often used during dosing sessions, yet empirical evidence about the safety, utility and acceptability of touch in PAT is lacking. This study reports participant perspectives on therapeutic touch collected within a Phase II randomised clinical trial of psilocybin-assisted therapy for Generalised Anxiety Disorder (PsiGAD-1). The researchers aimed to answer three questions: what are participants' perspectives on including therapeutic touch in psychedelic therapy; do attitudes to touch change across treatment; and what do participants perceive as the utility of touch in PAT. The paper emphasises the ethical considerations surrounding touch and frames the investigation as informing guideline development, therapist training, and safety protocols for PAT contexts where touch is used.
