Participation in medical decision-making: Attitudes of Italians with multiple sclerosis

BackgroundPatient involvement in decisions regarding their care has been advocated, but preferences have not been adequately canvassed, particularly in people with multiple sclerosis (MS).ObjectivesTo cross-culturally adapt and validate the Italian version of the Control Preference Scale (CPS) subsequently used to assess preferences of people with MS.MethodsTranslation–adaptation into Italian of CPS from the original Canadian English followed by administration in 140 people with MS from five Italian centers (with re-administration in 35) and semi-structured interview.ResultsCross-cultural adaptation of CPS was successful. The 140 people with MS, who varied in clinical and general characteristics, considered the CPS clear and acceptable. Test–retest reliability was moderate (weighted Kappa 0.65; p < 0.001). A collaborative role was preferred (61%), followed by passive (33%) and active (6%) roles. Education (odds ratio [OR] 2.43, 95% confidence limits [CI] 1.05–5.66) and length of follow-up at referral center (OR 0.36, 95% CI 0.14–0.92) were associated with choice of an active/collaborative role in the logistic model.ConclusionsThe Italian CPS was well accepted by our MS population. Our data indicate that a high proportion of Italians with MS prefer a more passive role and this should be considered during the clinical encounter.
