Background: Measuring and interpreting outcome is challenging in mental health services than in some other areas of health care. Objectives: The aims of this study were to (1) explore results of Patient-Reported Outcome Measures (PROMs) and Patient-Reported Experience Measures (PREMs) in psychiatric hospital settings, (2) describe the relation between generic PROMs (measure of well-being) and specific PROMs (disorder-specific symptom assessments), (3) describe the congruence between patients and clinicians evaluation of the care experience (based on Patients reported experience measures and Clinician reported experience measures). Methods: A total of 269 consecutive patients participated in this study. Results: (1) Subjective experience of well-being (outcome) improved after hospitalisation (+15%, avg). High satisfaction with subjective experience of care (85%, avg). (2) Significant correlation between patients’ assessment of subjective well-being (generic PROMs) and clinical improvement (specific PROMs) (p <0.007). (3) Significant correlation between patient and clinician experience of care (p= 0.002). Conclusions: One of the first French studies on the use of standardised PROMs and PREMs in psychiatric hospital settings. Results suggest that subjective well-being measures complement the assessment of the patient’s clinical symptoms and social functioning. The effectiveness of care depends on the consideration of these three dimensions. The use of core patient-reported measures, as part of systematic measurement and performance monitoring in mental health care, provides valuable input to the clinicians’ practice.
