Abstract

Mental health research increasingly relies on real-world clinical and survey data to understand patient preferences, treatment acceptability, and care outcomes. However, such data are frequently characterized by substantial class imbalance, reflecting unequal distributions across diagnostic categories, treatment modalities, and patient-reported preferences. This imbalance poses persistent methodological challenges for machine learning–based analysis, particularly when the objective is to model nuanced outcomes such as acceptability of psychotherapy, medication, or lifestyle-based interventions. The present study examines the role of contemporary data balancing techniques in improving the analytical reliability of machine learning models applied to mental health treatment preference data. Drawing on established theoretical frameworks for learning from imbalanced datasets and recent empirical studies in mental health informatics, this article synthesizes methodological insights with a focused application context relevant to low- and middle-income settings. The study outlines a structured analytical pipeline encompassing data preprocessing, sampling strategies, hybrid balancing approaches, and model evaluation under imbalance-sensitive metrics. Results indicate that appropriate balancing techniques are associated with improved minority-class representation and more stable predictive performance, particularly in settings involving patient acceptability and preference outcomes. The discussion situates these findings within broader debates on methodological rigor, ethical considerations, and interpretability in mental health machine learning research. The article contributes a comprehensive methodological perspective that supports more equitable and reliable computational analyses of mental health data, while acknowledging limitations related to generalizability, contextual variability, and evolving clinical practices.
