Phenomenological-control framing of suggestion-based interventions: a testable hypothesis for acceptability and implementation in psychiatric care.

This Hypothesis and Theory article draws on a targeted, non-systematic synthesis of relevant literature and does not report new empirical data. Suggestion-based interventions show clinical promise across several medical conditions, yet their uptake in routine care remains limited. Psychiatry may be a particularly informative context in which to examine framing-related barriers because treatment engagement, perceived agency, trust, acceptability, and appropriateness may be especially sensitive to how an intervention is described and understood. In response to these concerns, the article considers whether selected suggestion-based interventions could be presented through a phenomenological-control framing. Phenomenological control refers here to a patient-side capacity for the goal-directed regulation of subjective experience, whereas a phenomenological-control framing uses that capacity as the explanatory rationale for the intervention. The intervention itself remains a clinical procedure involving structured suggestions. The central hypothesis is that, relative to a hypnotic framing, a phenomenological-control framing may influence implementation-relevant responses without implying greater clinical efficacy. Patient-level predictions concern perceived agency, concerns about loss of control, acceptability, appropriateness, and willingness to engage. Provider-level predictions concern scientific credibility, appropriateness, and intentions to recommend, refer, adopt, or seek training. These predictions are conditional and may vary across individuals and contexts.
