RESUMO
INTRODUCTION: We aimed to investigate the nature of the associations between PD clusters and MDs, functionality and mental health services use. METHODS: This is a case register study of all cases with a diagnosis of PD detected clinically in a well-defined area in the province of Barcelona covered by 7 Community Mental Health Teams. DSM-IV diagnoses were established by fully trained psychiatrists. Data was also gathered on socio-demographic variables; functional status (GAF) and data on use of health resources, using a systematic computerized method. We performed a non-parametric univariate statistical analysis. RESULTS: We found a higher percentage of major depressive disorder (MDD) among cluster C patients (17%), followed by cluster A (10%) and cluster B (9, 8%). As for the comorbidity between PD clusters and dysthymic disorder, we found that the prevalence was higher among cluster B patients (23,7%) than cluster C (20,2%) or cluster A (7,1%). When considering both MDs together, we found the highest prevalence among cluster C patients (36,87%), followed by cluster B (33,5%) and cluster A (17,1%). Cluster A patients showed worse functioning and visited hospitals most. CONCLUSIONS: A high comorbidity between all MDs analyzed and personality disorders was found, being particularly prominent among cluster C PDs.
