Validation and Reliability of the Turkish Version of a Patient Satisfaction Survey for Comprehensive Medication...

Comprehensive Medication Management (CMM) is pivotal in optimizing clinical outcomes through personalized medication review and patient engagement. Patient satisfaction surveys, such as the Medication Management Patient Satisfaction Survey (MMPSS), play a crucial role in assessing the quality of these services. However, there is currently no Turkish version of the MMPSS available. This study aimed to translate, culturally adapt, and validate the Turkish version of the MMPSS to assess patient satisfaction with CMM services provided by pharmacists in Türkiye.

Following established guidelines for cross-cultural instrument validation, the MMPSS was translated into Turkish and culturally adapted. The survey underwent forward translation, expert panel review, back-translation, and pilot testing. Data collection occurred in a tertiary care university hospital between September 9, 2022, and March 21, 2023. Psychometric analyses included reliability testing (Cronbach's alpha), factorial validity using confirmatory factor analysis, and test-retest reliability using the Intraclass Correlation Coefficient (ICC).

A total of 124 participants (82.7%) completed the survey. Participants were mostly women (57.3%) and elderly, with a mean age of 70.43 years, three comorbidities, and six medications. The Turkish MMPSS demonstrated excellent internal consistency (Cronbach's α = 0.858) and test-retest reliability (ICC=0.937), confirming its reliability over time. Factor analysis supported a one-factor structure, consistent with the original MMPSS framework, and all items showed strong correlations.

The Turkish version of the MMPSS is a reliable and valid instrument for assessing patient satisfaction with CMM services in Türkiye. Its implementation can enhance the evaluation and improvement of clinical pharmacy services, ultimately promoting better patient care and outcomes.
