Rorschach assessment of primitive defenses: a review

The Lerner & Lerner Scale for assessing primitive defenses is reviewed. According to its conceptual roots, initial studies assessed the scale's efficacy in distinguishing groups of borderline patients from groups of other diagnostic entities. Later studies extended the use of the scale to assess various clinical groups assumed to have a borderline personality structure. Results from several studies indicate a high level of reliability as judged by degree of interrater agreement. In a host of studies, the scale was found to be valid in distinguishing borderline patients from other types of patients, eating disordered patients from normal controls, and gender disturbed children from normal controls. Another Rorschach scale for assessing primitive defenses was also reviewed and compared.
