Abstract
Background
The Process-Based Assessment Tool (PBAT), is an item pool showing promising results in assessing psychological processes of change relevant for both psychotherapy and research in its original English version. However, further research focusing on translation and validation in other languages is needed for broader applicability. This study aims to translate and validate the PBAT in Swedish, and to examine the relationship with common clinical outcome variables.
Methods
The PBAT and STOP-D were translated and culturally adapted to Swedish. The study included 427 Swedish-speaking participants recruited online, with a mean age of 48. The PHQ-4 and Single Item Stress Scale were used as criterion variables. Correlational analyses and the Boruta feature selection algorithm were employed for data analysis.
Results
The translated PBAT demonstrated significant correlations with clinical outcomes, indicating its effectiveness in a Swedish context. Positive PBAT items correlated with higher vitality and health, while negative items were predictive of sadness, anxiety, and stress. The Boruta analysis highlighted the importance of specific PBAT items to different clinical outcomes, underscoring the tool's validity.
Conclusion
The Swedish version of the PBAT shows strong validity and reliability in assessing psychological health. This study contributes to the cross-cultural applicability of the PBAT, offering a valuable tool for psychological assessment in the Swedish context.
