| Abstract: | The most scientifically appropriate conclusion to draw from the body of research on dialectical behavior therapy (DBT) is that it is probably useful in producing initial improvement on multiple variables relevant to outcome in borderline personality disorder, particularly parasuicidal behavior. These are promising and clinically relevant findings. However, its genuine efficacy in producing changes that last after the treatment has been discontinued is unknown. A major gap in the literature is the absence of any follow-up data at intervals appropriate for assessing the efficacy of a treatment for a disorder that is chronic by definition. The gap between the data and widespread beliefs about the efficacy of DBT is not, however, specific to DBT. A recent metaanalysis suggests that similar disparities are the norm in most research on empirically supported therapies, such as brief treatments for depression. |
