Abstract
OBJECTIVE: The aim of this study was to investigate the factors associated with non-adherence to medication in a large multi-center sample of homeless schizophrenia (HSZ) patients. METHODS: This multi-center study was conducted in four French cities: Lille, Marseille, Paris, and Toulouse. In addition to the Medication Adherence Rating Scale (MARS), sociodemographic information, history of homelessness, illness severity using the Modified Colorado Symptom Index (MCSI) and the Multnomah Community Integration Scale (MCAS), and drug information were collected. RESULTS: In total, 218 HSZ patients (16.1% women, mean age 36.8 ± 9.3 years) were included in this study. In the multivariate analysis, being a woman and having higher illness severity (MCSI score) and lower "acceptance of illness" (MCAS score) were significantly associated with lower MARS index scores. Compared to men, women had lower MARS dimension 1 ('medication adherence behavior') and dimension 3 ('negative side effects and attitudes toward psychotropic medication') scores. First-generation antipsychotic use was also associated with lower MARS dimension 3 scores. CONCLUSION:HSZ women reported lower adherence than men, mainly due to having more subjective negative side effects and worse attitudes toward psychotropic medication. Future longitudinal studies should confirm these findings and explore the applicability of specific pharmacological and non-pharmacological treatment strategies for HSZ women, including treatment dose adaptation and psychoeducation. Clinical trial number NCT01570712.
