Although Leichsenring and Leibing (1) attempted to do a conscientious job of comparing the efficacy of dynamic therapy to cognitive therapy in patients with personality disorders by using meta-analytic techniques, they failed to include several studies: two of avoidant and obsessive-compulsive personality disorder (2, 3) and one of borderline personality disorder (4). In addition, they did not include any studies involving group therapy. Omitting relevant studies when so few are available raises questions not only about the generalizability of this meta-analysis but also about the technology and methods used in selecting studies for inclusion. Thus, we strongly recommend that meta-analysts describe the exact terms used in searches and that searches using similar terms be conducted across different databases. There are limitations to blind computerized searches; therefore, searches must be supplemented by, for example, looking at references of relevant articles and by contacting experts.
