Who We Are, Where We Are: Mental Health at the Intersection of Person, Situation, and Large Language Models
Mental health is not a fixed trait but a dynamic process shaped by the interplay between individual dispositions and situational contexts. Building on interactionist and constructionist psychological theories, we develop interpretable models to predict well-being and identify adaptive and maladaptive self-states in longitudinal social media data. Our approach integrates person-level psychological traits with language-inferred situational features. Results show that our principled, theory-driven features provide competitive performance while offering greater interpretability. Qualitative analyses further highlight the psychological coherence of features most predictive of well-being. These findings underscore the value of integrating computational modeling with psychological theory to assess dynamic mental states in contextually sensitive and human-understandable ways.
Bridging Psychological Theory with AI for Mental Health
Mental health is not a static trait but a dynamic outcome shaped by ongoing interactions between person and context. In this work, we operationalized this psychological insight by combining person-level traits and situational characteristics — core tenets of interactionist and constructionist theory — to model well-being and adaptive self-states in language. Our theory-driven baseline, built from the Situational 8 DIAMONDS and language-inferred psychological traits, demonstrated strong performance while offering interpretable, psychologically grounded predictions. Features like positivity, satisfaction with life, and harmony in life emerged as key indicators of well-being, while markers of cognitive distortion and unmet affiliation needs were linked to maladaptive patterns. HaRT’s person-contextualized embeddings added value in modeling temporal variation, particularly for adaptive and maladaptive evidence detection. These findings highlight the value of bridging computational models with psychological theory — not only to improve prediction, but to ensure outputs are meaningful and human-understandable. Future work should explore how different contexts modulate trait adaptiveness, and how language-based systems might support more flexible, resilient self-states over time.

Theory-Driven Baseline vs. Advanced AI Performance
Our principled, theory-driven features, combining Situational 8 DIAMONDS (S8D) and Person-Level Traits (PLT), provide a strong interpretable baseline for well-being prediction. While advanced HaRT models show higher accuracy, the S8D+PLT approach offers transparent, psychologically grounded insights.
HaRT Model Enhances Predictive Accuracy
The Human Language Modeling (HaRT) approach, trained on temporal user histories, generates person-contextualized embeddings that significantly enhance predictive accuracy for both well-being scores and identification of adaptive/maladaptive self-states.
Key Psychological Features Identified for Well-being
Qualitative analysis reveals that features like 'satisfaction with life', 'positivity' in situation, and 'harmony in life' are positively correlated with well-being. Conversely, 'higher power belief', 'depression scale', and overall 'resilience score' are negatively correlated, providing interpretable insights.
Ethical Imperatives in Mental Health AI
The application of language models to mental health raises critical ethical concerns, including data privacy, potential for misdiagnosis due to probabilistic inferences, and biases in models trained on limited demographic data. Transparency, human oversight, and cultural sensitivity are paramount.

Ethical Framework for Mental Health AI Deployment
Deploying AI models for mental health requires careful consideration of ethical implications. The probabilistic nature of language-based inferences demands human oversight to prevent misdiagnosis or unwarranted interventions. Models trained on specific social media data may carry inherent biases, necessitating diverse training data and cultural sensitivity to ensure equitable application across populations. Transparency in how models interpret and use data, alongside robust consent mechanisms, is fundamental to respecting user autonomy and privacy.
Key Learnings: Human oversight is crucial, address model bias, ensure data privacy and informed consent, prioritize transparency.
