Translation, cultural adaptation and validation of the revised patients' attitudes towards deprescribing (rPATD) questionnaire in Romanian older adults

Abstract

Background: Deprescribing is part of ensuring appropriate medication use and may reduce medication-related harm. Capturing the beliefs and attitudes of patients towards deprescribing by using a validated tool may support optimizing medication use in practice.

Objectives: To translate, culturally adapt and validate the revised Patients' Attitudes Towards Deprescribing (rPATD) questionnaire in Romanian and to investigate the attitudes and beliefs of older adults towards deprescribing.

Methods: The rPATD questionnaire was translated using forward-backward translation into Romanian and culturally adapted. The psychometric properties were evaluated in older adults ≥65 years of age. Structural validity was assessed by item load on factors using an exploratory factor analysis (EFA) which was compared to the original English version and the internal consistency by Cronbach's alpha. Construct validity was evaluated by calculating the Spearman's rank correlation coefficients between the factor scores obtained using the revised version of the Romanian rPATD and scores on the Beliefs about Medicines Questionnaire (BMQ) Specific Concerns Romanian version. Floor and ceiling effect were also examined.

Results: We translated the questionnaire and administered it to 224 participants (median age 72 years [interquartile range: 68.0; 77.0]). In the EFA individual items loaded onto 4 factors, grouped similarly to the English version (Involvement, Burden, Appropriateness, Concerns about Stopping factors). Two items from each of the Involvement and Appropriateness factors were removed to improve factor loading and avoid cross-loading. The Cronbach's alpha values for the 4 factors ranged between 0.522 and 0.773. The scores for Burden and Concerns about Stopping factors were found to be positively correlated with BMQ Specific Concerns score. We identified a ceiling effect for one of the four factors (Involvement) and no floor effects.

Conclusions: The Romanian rPATD was validated in 4 factor structure similar to the original English questionnaire. The Romanian version of the questionnaire may support the health care professionals in Romania to initiate and support patient-centered deprescribing.
