Introduction: Health-related quality of life (HRQoL) is an accepted outcome measure in patients with depression.
Aim: Our study aimed at assessing QoL in depressed elderly patients with cluster C PDs, admitted to Psychiatric Clinic No II Targu Mures. Cluster C PDs is the most frequent diagnosis on axis II for depression.
Material and method: A sample of thirty elderly in-patients with cluster C PDs and depression was studied. Mental disorders were assessed based on DSM IV criteria, Hamilton scale of depression and SCID II (structured clinical interview for DSM). QoL was assessed with the aid of the World Health Organization Quality of Life instrument (WHOQoL-Bref), and the Global Assessment of Functioning scale (GAF).
Results: We formed high co-morbidity among depression and cluster C PD, especially dependent PD, which was associated with poor QoL. The WHOQoL physical health and social functioning were significantly associated with GAF. Conclusion and Discussion: PD symptoms in elderly patients appear to operate as co-factor that amplify or exacerbate the impact of depression on long-term functioning and QoL. We conclude that if co-morbid personality disorder is not treated, patients will respond less well to treatment for depression than do those without PD.
