Objective: To assess the personality characteristics of patients with repeated sexually transmitted diseases (STD).
Method: A case-control study comparing 101 STD repeaters (subjects with a lifetime history of three or more STDs) with 182 controls who had no history of STD. All subjects attended the City Department for Skin and Venereal Diseases in Belgrade (Yugoslavia) from June 1997 to April 1998. Personality characteristics was assessed by the Millon Clinical Multiaxial Inventory (MCMI).
Results: The analysis of MCMI test showed that STD repeaters had higher scores on narcissistic, antisocial and paranoid scales. The difference between STD repeaters and the controls was significant on antisocial, psychotic thinking and psychotic delusion scales, although scores on clinical syndromes were low for both cases and controls. Discriminant analysis showed that antisocial personality was predictive for STD repeaters.
Conclusions: This study support the hypothesis that STD repeaters are different from controls in terms of their psychological characteristics. The behaviour of STD repeaters is ego-syntonic, which makes the treatment of their personality difficult and emphasizes the importance of work on primary and secondary prevention of STD.
