Psychological state assessment

The manuals converge on the need for reliable questionnaire-based assessment across time points, with consistent timing, method, and recording of data. They all emphasise repeated or protocol-defined measurement of subjective state, mood, and related psychological outcomes, using validated instruments and careful interpretation of results. They also overlap in their focus on altered states and psychedelic phenomenology. The extracts refer to visual analog scales, mood rating instruments, retrospective post-session measures, and instruments for mystical-type effects and ego dissolution, alongside the need to recognise clinically important psychological change or risk. They differ mainly in scope and specificity. The SAP lists a broader clinical battery, including MEQ-30, EDI, MADRS, ACQ, CGI-S, PGIC, CIWA-Ar, SIP, SETS, EQ-5D-5L, and TLFB, while the study reports focus more narrowly on session-based subjective effects and retrospective altered-state measures such as 5D-ASC and SOCQ/MEQ. The comparative study also highlights interpretation of specific phenomenological dimensions, including oceanic boundlessness, anxious ego dissolution, and visionary restructuralization, which are not named in the SAP extract.
