Avaliação diagnóstica e evidências de validade de instrumentos para o transtorno de personalidade borderline

Abstract

Borderline Personality Disorder (BPD) is defined by a pervasive pattern of unstable behavior that causes social, emotional and interpersonal damage, in addition to being associated with self-injurious and life-threatening behavior. This dissertation aims to contribute to an area of psychological assessment of Borderline Personality Disorder. To this end, two surveys related to the topic were conducted. The first study concerns an integrative review of the characteristics of self-injurious risk behavior (with and without suicidal ideation) in the population diagnosed with BPD and the respective risk factors. The findings of this first study indicated that BPD and BPD traits were the variables with the greatest predictive power for self-injurious behavior and suicide. Self-injurious behavior without suicidal intent was shown to be a predictive factor for suicide in the general female population, but not for BPD. Self-injurious behavior patterns, rather than their mere existence (random or mixed patterns), can be predictive factors for suicide in the population with BPD. Impulsiveness and depression are factors related to suicide in a population with BPD. The second study is a translation and cross-cultural adaptation of an assessment instrument aimed at TPB, The Life Problem Inventory. The instrument was submitted to the entire process of evidence of content validity, indicating the permanence of its main characteristics for adaptation to adult and clinical age. The pilot indicated excellent audience understandability and comprehensiveness.
