The factor structure of the Zanarini Rating Scale for Borderline Personality Disorder: Exploratory Structural Equation Modelling and measurement invariance over time.

ABSTRACT:

Objectives

There is a lack of independent longitudinal evidence on the factor structure and validity of the Zanarini Rating Scale for Borderline Personality Disorder (ZAN-BPD). This study aimed to investigate the dimensionality of ZAN-BPD and its conceptual consistency over time.

Methods

Adult BPD participants (n = 276) were recruited for a multicentre, two-arm randomised clinical trial with ZAN-BPD measured at baseline and follow up at 12, 24 and 52 weeks. The construct and stability of the ZAN-BPD across 52 weeks was examined through a measurement equivalence/invariance procedure via Exploratory Structural Equation Modelling.

Results

Factor analysis results showed that the ZAN-BPD had a bi-2 factor structure that was stable over 52 weeks with a general factor and tw
