Aim: There is lack of research on the study of clinical personality traits in recent onset of psychosis (ROP) patients. The aims of this research were to study the relations among psychosocial, personality and clinical characteristics in ROP patients and also the effect that significant variables had on the different domains of Quality of Life (QoL).
Methods: Data for these analyses were obtained from 81 ROP patients. The Millon Clinical Multiaxial Inventory, the Positive and Negative Syndrome Scale and the World Health Organization Quality of Life Brief Scale were used to assess personality, symptoms and QoL.
Results: Correlations between the negative symptoms and the physical, psychological and social domains of QoL, and the disorganized symptoms and physical domain, were found. Furthermore, the physical, psychological and social relationship domains of QoL were lower in patients with schizoid traits and the psychological domain was lower in patients with depressive traits. In contrast, the psychological and social domains were higher in patients with histrionic traits, while the physical domain was higher for patients with narcissistic traits. Multiple linear regressions demonstrated that negative symptoms and narcissistic and depressive traits explained 16.9% of the physical domain. Narcissistic and depressive traits explained 15% of the psychological domain. Finally, the negative symptoms and histrionic traits explained 13.7% of the social domain.
Conclusions: QoL seems to be better explained by negative psychotic symptoms and some clinical personality traits. Our results support the importance of integrated intervention approaches that consider personality.
