The Role of Big Five Personality Factors and Defense Mechanisms in Predicting Quality of Life in Sexually Dysfunctional Female Patients

Sexual dysfunction can lead to behavioral problems and reduction in a person''s quality of life. In 50 % of patients with personality disorders، there is also sexual dysfunction. Psychoanalysis approach attributes the cause of sexual dysfunction to a kind of fundamental anxiety as well as the use of immature mechanisms in these patients. The purpose of this study was to investigate the role of big five personality traits and defensive mechanisms in predicting these patients'' quality of life. Statistical sample of this research included 80 women attending sexual health and family clinics of Shahed University using accessible sampling during 2010 and 2011. These subjects were given the Neo Personality Inventory Traits، Defensive Mechanisms، and the World Health organization Quality of Life Questionnaires to answer. The findings showed that personality traits could predict the quality of life in woman with sexual dysfunction. Moreover، among those five personality traits، neuroticism (b:. /24 P=. /04) and conscientiousness (b:. /31 P=. /03) were able to predict the quality of life while predictability rate of both factors was 37% of variance on the whole (p=0/05). Based on regression analysis، there was a significant relationship between the quality of life and defensive mechanisms so that using more mature defensive mechanisms (b:. /37 P=. /006) and immature defensive mechanisms (b: -. /31 P=. /02) could significantly predict quality of life (p=0/0001). Also، neurotic defensive mechanisms were not significant predictors of these women'' quality of life. (b;. /04 P=. /78).
