Enhancing Large Language Models for Psychiatric Behavior Understanding in Motivational Interviewing

Core Concepts
Introducing the Chain-of-Interaction method to enhance large language models for psychiatric decision support by incorporating domain knowledge and patient-therapist interactions.
The content discusses the importance of automatic coding of patient behaviors during motivational interviewing sessions. It introduces the Chain-of-Interaction (CoI) prompting method to contextualize large language models (LLMs) for psychiatric decision support by focusing on dyadic interactions. The CoI method breaks down the coding task into three key reasoning steps: extracting patient engagement, learning therapist question strategies, and integrating dyadic interactions between patients and therapists. Experiments demonstrate the effectiveness of CoI with multiple LLMs over existing baselines.

"Experiments on real-world datasets can prove the effectiveness and flexibility of our prompting method with multiple state-of-the-art LLMs over existing prompting baselines." "Our experiments demonstrate the critical role of dyadic interactions in applying LLMs for psychotherapy behavior understanding."
"Automatic coding patient behaviors is essential to support decision making for psychotherapists during motivational interviewing." "While past studies have shown concatenating patient utterance and its previous utterances can improve prediction accuracy of the MISC coding task, how the patient-therapist interactions can inform model predictions is underexplored."

How can incorporating domain-specific knowledge improve the performance of large language models in behavioral coding tasks?

Incorporating domain-specific knowledge can significantly enhance the performance of large language models (LLMs) in behavioral coding tasks by providing them with a structured understanding of the task at hand. In the context of motivational interviewing (MI), where LLMs are used to code patient behaviors, integrating domain knowledge from MISC coding manuals allows the models to mimic human professionals' reasoning processes. By breaking down the task into key reasoning steps and guiding LLMs through stages like Interaction Definition, Involvement Assessment, and Valence Analysis, they gain insights into therapist-patient interactions and psychological concepts crucial for accurate coding. This approach enables LLMs to leverage specialized information that may not be present in raw data alone, leading to more informed predictions aligned with expert annotations.

How might integrating audio features from therapy recordings impact the accuracy of automatic behavioral coding?

Integrating audio features from therapy recordings could have a significant impact on improving the accuracy of automatic behavioral coding. Audio data contains valuable cues such as tone, pitch, pauses, and other vocal characteristics that are not captured in text transcriptions alone. By incorporating these auditory signals into analysis alongside textual data, machine learning models can gain a more comprehensive understanding of patient-therapist interactions during MI sessions. This multimodal approach could provide additional context for interpreting nuances in communication that may influence behavior coding outcomes. Furthermore, audio features could help capture emotional nuances and subtle cues that text alone may not fully convey, enhancing the overall accuracy and depth of automatic behavioral coding systems.

What are potential ethical considerations when using large language models for mental health applications?

When utilizing large language models (LLMs) for mental health applications, several ethical considerations must be taken into account: Privacy Concerns: Protecting patient confidentiality is paramount when working with sensitive mental health data. Ensuring proper anonymization techniques are employed to safeguard individuals' identities. Bias Mitigation: Addressing biases within LLMs is crucial to prevent perpetuating stereotypes or unfair treatment based on demographic factors like race or gender. Informed Consent: Obtaining explicit consent from patients before using their data for training or analysis purposes is essential. Transparency: Providing clear explanations about how LLMs operate and making results interpretable ensures accountability and trustworthiness. Data Security: Implementing robust security measures to protect against unauthorized access or breaches that could compromise patient information. 6Clinical Oversight: Ensuring trained professionals oversee LLM recommendations to avoid misinterpretation or inappropriate interventions based solely on automated outputs. By adhering to these ethical guidelines and continuously monitoring model behavior within mental health settings, the responsible use of LLMs can lead to positive outcomes while upholding patient well-being and privacy
