Spanish Adaptation and Validation of the Recovery Process Inventory (RPI) in People with Mental Disorders

Backgorund: This study aimed to adapt and obtain validity evidence of the Spanish version of the Recovery Process Inventory (RPI-S) underlining the importance of hope and social support in personal recovery. The RPI-S was developed through a systematic process, ensuring semantic, linguistic, and contextual equivalence to the original instrument. Method: The psychometric properties were tested with 266 participants with severe mental disorders, following STROBE guidelines. Confirmatory factor analysis supported a four dimensions structure for assessing personal recovery. Results: The RPI-S showed evidence based on relations to other variables and evidence based on internal structure. Conclusions: The findings suggest that the RPI-S is a reliable tool for assessing recovery in Spanish-speaking people with severe mental disorders, highlighting the critical roles of hope and social support in recovery.
