Content of the questionnaire
Target audienceAdults
ApplicationThe Borderline Symptom List (BSL) has been developed to diagnose and to identify the severity of Borderline Personality Disorders. The BSL is available in two versions, a longer 95-item version and a shorter 23-item version.
CompositionBoth versions of the BSL measure different facets of Borderline Personality Disorders on 5-point Likert scales. While this results in different subscales for the longer 95-item version, the shorter 23-item version only has a total score as outcome. The longer version is divided into the scales self-perception, affect regulation, self-destruction, dysphoria, loneliness, intrusions and hostility. Both versions additionally also measure the total well-being on a scale from 0% to 100% as well as the frequency of several kinds of dysfunctional behaviors.
Psychometric properties
Reliability & ValidityInternal consistency as well as test-retest reliability of the BSL-95 have been established with excellent values (Cronbach’s Alpha = .97, 1-week retest correlation = .84). Convergent and divergent validity have been established by comparison with relevant instruments. The results are overall good to very good. Generally, the BSL-23 showed similar results as the BSL-95.
NormsThere are percent ranks available for the BSL-23 and the BSL-95 scales.
