Personality Disorders and Unhealthy Lifestyle: A Cross-Sectional Study

Personality disorders (PDs) would be associated with an unhealthy lifestyle. To date, however, there have not been sufficient studies on the relationship between them. This study aimed to investigate the association between personality disorders and an unhealthy lifestyle by using an analytical cross-sectional study. We selected 1538 married women based on the multistage cluster sampling method. We used the Millon Clinical Multiaxial Inventory (MCMI) and Lifestyle Questionnaire (LSQ). Apart from descriptive statistics, a one-sample t-test, multivariate analysis, and structural equation modeling were used. Analysis of the data suggested that negativistic (β= -0.321), schizotypal (β= -0.285), schizoid (β= -0.159), borderline (β= -0.136), melancholic (β= -0.079) PDs had a significant association with an unhealthy lifestyle, respectively. Cluster A personality disorders were prone to an unhealthy lifestyle more than the other two clusters.
