Abstract

The Medication Adherence Rating Scale (MARS) is one of the most widely ă used measurements of adherence in schizophrenia (SZ), but there is no ă available data regarding its psychometric properties in homeless SZ ă patients (HSZ). The aim of this study was therefore to assess the ă psychometric properties of the MARS in a large multicenter sample of HSZ ă subjects. This multi-centre prospective study was conducted in the ă following 4 French cities: Lille, Marseille, Paris and Toulouse. Three ă hundred and fifty-three patients were included. The 3-factor structure ă of the MARS was confirmed using confirmatory factor analysis: RMSEA = ă 0.045, CFI = 0.98, TLI = 0.97 and WRMR = 0.76. The unidimensionality of ă each factor was supported by the satisfactory INFIT statistics. Item ă internal consistencies were all higher than 0.20 and the ă Kuder-Richardson were higher than to 0.6, except for factor 2, which was ă closed to 0.5. Significant associations with symptoms, functioning and ă quality of life showed satisfactory external validity. The acceptability ă was satisfactory with missing data lower than 5% for each dimension. ă The MARS is a short self-administered instrument with acceptable ă psychometric properties in homeless SZ patients that yields interesting ă information about medication adherence.
