Personality disorder increases risk of low quality of life among women with mental state disorders.

BACKGROUND

Limited data are available examining the relationship between mental state disorders (mood, anxiety, substance use, eating disorders), their co-occurrence with personality disorder (PD), and quality of life among women. We aimed to investigate these relationships in a sample of women from the community.

METHOD: Women from the Geelong Osteoporosis Study (n = 717) were administered the Structured Clinical Interview for DSM-IV (SCID-I/NP and SCID-II) and the World Health Organisation Quality of Life scale (WHOQOL-BREF). Weight and height were measured and lifestyle and demographic factors were self-reported. Logistic regression models (odds ratios with 95% confidence intervals) were undertaken to investigate associations among groups (mental state disorders, co-occurring mental state disorders with PD, and controls) and the WHOQOL-BREF domains (physical, psychological, social, and environmental health) while testing for potential confounding.

RESULTS

Results indicated that mental state disorders were associated with increased risk of low quality of life in physical, psychological, social, but not environmental domains, compared to controls. This risk was increased among women with co-occurring PD across all domains compared to both controls and those with mental state disorders.

CONCLUSION

These findings add evidence suggesting poor quality of life is experienced by those with mental state disorders, and that this is worsened by the experience of co-occurring PD.
