ABSTRACT

Objective To study the relationship between personality and defense mechanism of obsessivecompulsive disorder (OCD) patients.Methods Thirty-four OCD patients were tested with Swedish University Scales of Personality(SSP) and defensive style questionnaire( DSQ), and the result was compared with that of thirty-one normal controls.Results The SSP scores of STA,PsTA,SS,E,TI and M of OCD patients were significantly higher than that of normal controls (t = 2.06 ～ 5.10, P ＜ 0.05 ).Comparing with normal controls, OCD patients tended to use immature and intermediate mechanism such as projection, passive aggression, unconscious emerge, phantasy, withdrawl and reaction formation, but less used mature mechanism such as sublimation, suppression and humor (t = -2.27 ～ 6.73, P＜ 0.05 ).All subscales of SSP in OCD patients, excluding SD and D, had positive correlation with total score of immature mechanism (r = 0.375 ～ 0.719, P ＜ 0.05 ).The OCD patients' SSP scores of STA had positive correlation with mature mechanism (r = 0.378, P ＜ 0.05 ).The OCD patients' STA, PsTA, I, AS, E, M,VTA and PhTA score of SSP had positive correlation with intermediate mechanism (r= 0.381 ～0.548, P＜ 0.05 ).All subscales of SSP in OCD patients, excluding SD, had positive correlation with total score of concealment (r =0.342 ～ 0.530, P ＜ 0.05 ).Conclusion OCD patients have the neurotic and aggressive features of personality;and the personalities of OCD patients have significant correlation with defense mechanism.
