Description: A cognitive-behavioral psychotherapy, dialectical behavior therapy (DBT) was originally developed to treat individuals with suicidal behavior and borderline personality disorder (BPD). Since its inception, DBT has expanded to treat a wide range of disorders, such as substance dependence, eating disorders, depression, post-traumatic stress disorder, and personality disorders other than borderline personality disorder. In addition to treating new clinical populations, the method of treatment delivery for DBT has undergone revision. Standard or comprehensive DBT includes weekly individual psychotherapy, group skills training class, phone coaching, and therapist consultation team. Recent adaptions of DBT have, however, focused on DBT Skills Training (DBT-ST) as a standalone treatment. When comparing standard DBT to DBT-ST treatment in individuals with BPD, research has shown that both conditions report similar improvements, including reductions in frequency and severity of suicide attempts, suicidal ideation, and crisis services although standard DBT may be more effective in some areas. Given the popularity of DBT-ST the increasing use of DBT for populations other than what it was originally intended to treat, it is crucial to develop methods for the careful evaluation of the accumulation of evidence in support of DBT. The purpose of the present study is to evaluate the current evidence of the effectiveness of using standalone DBT-ST to treat BPD and other clinical populations. In this study, a random-effects meta-analysis will be used to evaluate DBT-ST literature. In addition, the current study will use relatively new tools for the post-publication evaluation of research including a p-curve analysis to examine the false-positive rate and additional technologies to examine errors in statistical reporting. A preliminary p-curve analysis of the selected articles displayed right-skewed p-values, indicating evidential value or true effects for DBT-ST. The results will be discussed in the context of improving the reproducibility and replicability of adaptions for DBT.
