Conduct qualitative, client-centered inquiry

The manuals converge on the value of qualitative, client-centred inquiry as a way to understand subjective psychedelic or treatment experience. Across the extracts, the emphasis is on eliciting the patient’s own perspective, using semi-structured or qualitative interviewing, and attending to meaning, change, and perceived impact rather than relying only on external categories or outcome measures. They also overlap in their attention to specific domains of experience, including anxiety, quality of life, values, daily life change, and meaning. One source adds that qualitative interviewing should be non-leading and sensitive to altered-state narrative and psychological vulnerability, while another highlights listening for patient-defined core therapeutic elements and comparing recurring themes across cases. The main differences are in scope and emphasis. One manual frames the method as optional qualitative or semi-structured interviews and mentions trained microphenomenology where applicable, another focuses on semi-structured interviews in a clinical trial context, and a third broadens the lens to include both client and practitioner perspectives and to complement outcome measurement. Sources differ on whether the primary aim is detailed subjective change, process evaluation across cases, or identifying meaningful aspects of the therapeutic setting.
