Patient-Reported Experiences in Chronic Dermatological Conditions: Validation of the Romanian PSPSQ 2.0 Within Contemporary Dermatologic Care Pathways

Background/Objectives: Chronic dermatological conditions increasingly require complex and patient-centered therapeutic management, including biologic therapies, injectable treatments, and multidisciplinary care. In this context, patient-reported experience measures (PREMs) may provide valuable insight into the quality and effectiveness of pharmacist-delivered care. This study aims to translate, culturally adapt, and evaluate the psychometric performance of the Patient Satisfaction with Pharmacist Services Questionnaire (PSPSQ 2.0) as a patient-reported experience measure in Romanian patients with chronic dermatological conditions. Methods: A cross-sectional validation study was conducted in community pharmacies across Romania (N = 220). The questionnaire was translated using a structured forward-translation and expert review process, in accordance with ISPOR and COSMIN recommendations. Internal consistency was assessed using Cronbach’s alpha and item-level statistics. Construct validity was examined using exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and bifactor modeling. Known-groups validity and floor and ceiling effects were also evaluated. Results: The Romanian PSPSQ 2.0 demonstrated excellent internal consistency (α = 0.978; subscales α = 0.961–0.969). EFA indicated a dominant single-factor structure, explaining 84.0% of the variance. In CFA, the original three-factor model showed excellent relative fit (CFI = 0.999, TLI = 0.999), although RMSEA indicated some model misfit (0.109). Bifactor analysis revealed a strong general satisfaction factor, with consistently high loadings (0.80–0.99), suggesting that most item variance is attributable to a global patient satisfaction construct. These findings support the use of the instrument as a global measure of patient experience within contemporary dermatologic care pathways. Conclusions: The Romanian version of the PSPSQ 2.0 demonstrates excellent reliability and acceptable construct validity as a PREM for assessing patient satisfaction with pharmacist services. The findings support the use of total scores as a robust indicator of patient experience, while domain-level interpretation should be approached with caution due to substantial overlap between dimensions. This instrument may support the integration of patient-reported measures into routine evaluation of pharmaceutical care.
