MAP+PE (Multimodal Affective Psychophysiology for Prolonged Exposure) is a research prototype for quantifying session-level process in Prolonged Exposure (PE) for PTSD. A recorded session is transcribed and speaker-diarized on the clinician's own computer, parsed into the PE session structure, and aligned on a single clock with clinician-logged SUDS and ECG/EDA from an open-source acquisition rig.
From these streams it derives the process indices emphasized in emotional processing theory and the PE literature: peak and end-of-exposure SUDS, within- and between-session change, autonomic reactivity during imaginal exposure, narrative tense and avoidance markers, and candidate hotspots (Foa & Kozak, 1986; Jaycox et al., 1998; Nijdam et al., 2013; Sripada & Rauch, 2015; Wangelin & Tuerk, 2015). Output is evidence-linked, rule-based guidance for the next session, automated fidelity indicators for clinician confirmation, and a longitudinal record that includes the PCL-5.
Each panel has its own scale. SUDS: filled circles were entered by the clinician, hollow circles were found in the transcript. Triangles above the segment ribbon mark the three highest-arousal moments of the narrative. Vocal arousal indexes activation, not a specific emotion. The live readouts above show sparklines of the last three minutes.
Each card links to the moments behind it. Click a quote to move the cursor there and open the transcript.
Keyword proxies, not validated codes. PE asks for first-person, present-tense narration with sensory detail, thoughts and feelings; skipping and vague phrases can mark avoided content.
Each item has one definition, shown under its name, that both the automated indicator and the rater use, on the same scale. The automated column is a first pass from the recording; the rating is the fidelity record. Ratings that differ from the automated indicator are flagged and agreement is reported; the automated column can be hidden to rate blind. Try it: choose ratings, enter any ID (for example DEMO-1) and save; nothing leaves your browser. The default items are adapted from the PE session outline and can be replaced with a site's PE fidelity checklist.
The app produces a printable clinician report and a plain-language progress sheet for the patient, which leaves out clinical tallies and quotes. Download the versions generated from this example:
During the session the clinician marks segments (check-in, homework review, imaginal exposure, processing) and logs SUDS with a keypad, while the app controls the physiological recording. Afterward, everything runs on the clinician's own computer: raw audio and raw signals are deleted once analyzed, and the saved record is encrypted.
The feedback draws on the exposure-therapy literature on emotional engagement, between-session change in distress, hotspots in trauma memories and physiological reactivity to trauma imagery. The rules are transparent and every flag shows its evidence.
