Abstract

Background

This study examines the validity and screening properties of the Borderline Syndrome Index – BSI (developed in the USA) for categories of the Personality Assessment Schedule – PAS (developed in the UK).

Method

Patients were recruited by case control sampling. Chance corrected agreement between instruments and screening properties of the BSI were calculated.

Results

The BSI proved a moderately sensitive but non-specific screen. Questionnaire scores were highly correlated with symptom measures.

Conclusions

The results do not support the validity of the BSI or its use as a screening instrument. BSI scores may be distorted by current symptoms.
