Impact of therapeutic education on the evolution of social representations of medication in patients with Parkinson's disease: A quantitative and qualitative study (ETPARK REMED)

Abstract

BackgroundAmong the workshops of our therapeutic patient education (TPE) program, the medication workshop (TPEM workshop) is very frequently proposed to patients in view of the difficulties they encounter related to the complexity of managing antiparkinsonian treatment. Patients’ appropriation of their medications could depend on their social representations. ObjectivesTo evaluate the effect of our TPEM workshop on the social representations PD patients have of their medications and to compare it with that of another therapeutic intervention such as a talking group defined as the control group. MethodsThis single-center, prospective, randomized, parallel-group study investigated the social representations of medication through a questionnaire on knowledge about antiparkinsonian medications, a questionnaire on beliefs about medication (BMQ), and a word association task. ResultsIn the TPEM group (n=16), the workshop induced significant effects over time on the knowledge questionnaire (P=0.01), BMQ specific necessity and concerns scores (P=0.04 and 0.01, respectively), necessity-concerns differential (P=0.04), and BMQ general harm (P=0.04). No significant difference was found in the talking group (n=6). Comparison of the two groups showed a significant difference of the BMQ general harm with a decrease in belief in the harmfulness of the medications in the workshop group (P=0.03). The results of the verbal association task showed a modification in the content and structure of the social representations of medication in the TPEM group. DiscussionThe TPEM workshop helped reduce initial negative aspects of medication representations. Improved knowledge of their medication allowed patients to feel more competent and legitimate in communicating with caregivers, modifying their beliefs about medications. Indeed, the medication was perceived as less restrictive, care becoming central as shown by the emergence of the medical team in the social representations of the medication. ConclusionAll the results show a specific beneficial effect of the TPEM workshop through an evolution of the social representations of medications, which became more positive in our PD patients.
