Can we measure therapist-patient alliance from dialogue turns in real time?
Explores whether computational methods can detect working alliance quality at turn-level resolution during therapy sessions, enabling immediate feedback on whether the therapeutic relationship is strengthening.
COMPASS uses sentence embeddings (SentenceBERT, 384-dimensional) to project each dialogue turn onto representations of the 36-item Working Alliance Inventory. The result: a 36-dimensional working alliance score for every patient and therapist turn, decomposable into three subscales — task (collaborative nature), bond (affective connection), and goal (agreement on objectives). Combined with Temporal Topic Modeling using the Embedded Topic Model (ETM), this produces turn-resolution topic scores that track conversation focus over time.
Analyzing 950+ sessions across anxiety, depression, schizophrenia, and suicidality reveals condition-specific dynamics. Anxiety and depression sessions show convergence in bond and task scales as therapy progresses — a positive signal of alliance formation. Schizophrenia and suicidality sessions do not show this convergence. Suicidality trajectories are notably more spread out in bond and task scales, indicating significant patient-therapist misalignment.
The interpretable output identifies actionable patterns: discussing "Emotional States and Mental Health" increases task and bond scales for depression but decreases them for suicidality. Topic-to-alliance mapping enables therapists to identify which conversational strategies are working or failing for each condition — something previously requiring clinical intuition.
Since Can conversation structure predict dialogue success better than content?, alliance trajectories may represent a domain-specific instance of a general phenomenon: the shape of the conversation carries diagnostic information independent of content. The therapeutic application — real-time feedback on whether alliance is forming or deteriorating — is more clinically mature than general conversational geometry, because it maps onto a validated clinical construct (WAI).

Can conversation structure predict dialogue success better than content?
Does the geometric shape of how dialogue unfolds—timing, repetition, topic drift—matter as much as what people actually say? This explores whether interactive patterns hold signals hidden in word choice alone.
general conversational geometry; COMPASS is domain-specific instance for therapy
-
Can tracking dialogue dimensions simultaneously reveal hidden conversation patterns?
Does encoding linguistic complexity, emotion, topics, and relevance as parallel temporal streams expose emergent patterns that traditional statistical analysis misses? This matters because conversation success may depend on interactions between dimensions, not individual features alone.
multi-dimensional temporal tracking; COMPASS tracks WAI dimensions similarly
-
Is conversational presence more therapeutic than clinical technique?
Does therapeutic AI's benefit come from having an attentive listener rather than from delivering evidence-based techniques like CBT? This challenges decades of chatbot design focused on clinical content.
if conversational presence matters, these trajectory features may measure it
