The Process-Based Assessment Tool (PBAT) is integral to indeonomic understanding and facilitation of psychological change within therapeutic settings. This study presents the Swedish validation of the PBAT, emphasizing a novel analytical approach using the Boruta algorithm to identify key clinical outcomes associated with its items. By translating and culturally adapting the PBAT and STOP-D into Swedish with427 participants, mean age of 48. Utilizing the PHQ-4 and Single Item Stress Scale as criterion measures. Analyses revealed significant correlations between PBAT items and clinical outcomes, validating its application in a Swedish context. The Boruta algorithm pinpointed specific PBAT items that are most predictive of clinical outcomes such as vitality, health, sadness, anxiety, and stress. This feature selection technique underscored the PBAT's nuanced capacity to identify psychological processes impacting clinical outcomes. This Boruta-driven approach not only enhances our understanding of the PBAT's utility in clinical assessment but also sets a precedent for employing advanced data analysis techniques in psychological research.
