Summary of Study Hypothesis. Leichsenring and Leibing (2003) addressed several questions in their study: What is the evidence of improvement in symptoms, social functioning, or core psychopathology after psychodynamic therapy or cognitive therapy? Is there evidence of improvement in specific types of personality disorders after psychodynamic therapy or cognitive behavior therapy?, Do individuals with personality disorders recover after psychodynamic therapy or cognitive behavior therapy? Are there differences between self-report and observational measures? Is there a correlation between outcome and duration of treatment? What other factors are connected with outcome (gender, inpatient versus outpatient status, use of therapy manuals, experience of therapists?
Subject-descriptors. Personality disorders are characterized by long-standing and pervasive dysfunctional patterns of cognition, affectivity, interpersonal relations, and impulse control that cause considerable personal distress. The number of patients with personality disorders is considerably prominent (the prevalence of borderline personality disorder is estimated to be between 15% and 25%) and there is a considerable lack of empirical research on the effectiveness of psychotherapy in treatment with these …show more content…
The conclusions that both psychodynamic therapy and cognitive behavior therapy are effective methods of treatment for personality is supported statistically. The evaluation of the meta-analysis yielded an overall effect size of 1.46 and 1.00 respectively including only sources that used standardized methods of diagnosis for personality disorders; studies that applied reliable and valid instruments for assessment and reported data that allowed calculation of with-in group effect sizes or assessment of recovery rates. When necessary the authors even went so far as to use other statistics to calculate effect sizes such as t or chi-square
