Abstract
The revised Patients' Attitudes Towards Deprescribing (rPATD) questionnaire allows capture of the beliefs and attitudes of older adults and caregivers towards deprescribing.
To translate and validate the rPATD questionnaire into French.
The French rPATD was translated using forward-backward translation. Psychometric properties were evaluated in both older adults ≥65 years living in the community or in institutions and who were taking at least one chronic medication and in caregivers of older adults with similar characteristics. Participants were recruited in four French-speaking countries (Belgium, Canada, France and Switzerland). Face and content validity were assessed during the translation process. Construct validity (exploratory factor analysis (EFA)) and internal consistency (Cronbach's alpha) were investigated in questionnaires without missing data. Test-retest reliability was evaluated using intra-class correlation coefficient (ICC) in a sample of participants.
In total, 320 questionnaires from older adults and 215 questionnaires from caregivers were included to evaluate construct validity and internal consistency. EFA extracted four factors in the older adults' and caregivers' versions of the questionnaire consistent with the English rPATD. The extracted factors related to the perceived burden of medication taking, the beliefs in appropriateness of medications, concerns about stopping medications and the level of involvement in making decisions and of knowledge of medications. Internal consistency was satisfactory for three factors for both versions (Cronbach's alpha >0.70), with lower internal consistency in the concerns about stopping factor. Test-retest reliability was overall good for all factors in the caregivers' version (ICC > 0.75) while for the older adults' version, moderate (ICC range: 0.75-0.50) to good ICC values were found.
The French rPATD presents globally good psychometric properties and can be used to explore attitudes towards deprescribing in French-speaking older adults and caregivers.
