A cross-sectional study was carried out in 162 patients diagnosed with schizophrenia in Spain. The PRISS measures the presence, frequency, concern and interference with daily life of self-reported experiences related to the main symptoms observed in these patients. The psychometric analysis included test-retest reliability, internal consistency and structural and convergent validity. The 28-item PRISS showed good test-retest reliability as 64.3% of the intraclass correlation coefficient values were between 0.40 and 0.79, which were statistically significant (p  Our results indicate that the PRISS appears to be a brief, reliable and valid scale to measure subjective experiences in schizophrenia and provides valuable information complementary to clinical evaluation.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/patient-reported outcomepatient-reported outcome measureschizophreniasubjective experiencesCross-Sectional StudiesHumansPatient Reported Outcome MeasuresPsychometricsReproducibility of ResultsSchizophreniaSurveys and Questionnairesresearch article35188673open access10.1111/acps.134171600-0447https://riuma.uma.es/xmlui/bitstream/10630/25773/1/Acta%20Psychiatr%20Scand%20-%202022%20-%20Moreno%e2%80%90K%20stner%20-%20Patient%e2%80%90reported%20impact%20of%20symptoms%20in%20schizophrenia%20scale%20%20PRISS%20%20.pdf
