Introducing a short self-report for the assessment of DSM–5 level of personality functioning for personality disorders: The Self and Interpersonal Functioning Scale.
Аннотация:In the present study, we report on the development and validation of the Self and Interpersonal Functioning Scale (SIFS), a 24-item self-report questionnaire designed to assess the four core elements of personality pathology (Identity, Self-direction, Empathy, and Intimacy) from the DSM-5 Level of Personality Functioning (LPF) for personality disorders (PDs).Participants from a community sample (n = 280) and patients from a specialized treatment facility for PDs (n = 106) were included in the validation sample.Overall, the SIFS showed sound psychometric properties.A second-order factor solution, which consisted of the four LPF elements and an overarching personality pathology factor, showed the best fit indices.The four SIFS elements showed a well-differentiated and conceptually meaningful pattern of associations with related constructs.In light of these results, the SIFS should be considered as a promising, concise measure of Criterion A for clinical screening and research purposes.Its relative strengths and limitations in contrast with other existing self-report measures of Criterion A are discussed.
