Translation and adaptation of the Level of Personal Functioning Scale-Brief Form 2.0

Abstract

The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) introduced the concept of levels of personality functioning, which indicates the severity of personality disorders. In our knowledge, there are no concise psychometric instruments for assessing the level of personality functioning in Spanish, so the objective of this study was the translation and adaptation of the Level of Personal Functioning Scale-Brief Form 2.0. The sample (N = 361) was collected via Internet. The results of the confirmatory factor analysis showed that the instrument has a bifactorial structure and it can be used, in addition to its two dimensions, self-functioning and interpersonal functioning, a factor that represents general functioning. Evidence of internal consistency is provided, and significant correlations were found with all personality traits.
