An Exploratory Factor Analysis on the Boundary Questionnaire 18: Insights for Future Research

Abstract

The current study examines some Boundary Questionnaire 18 (BQ18) psychometric properties, a shorter version of the Boundary Questionnaire (BQ). The current study examines the BQ18 through factor analysis to understand more about the structure of the inventory. At this point, the BQ18 has not been examined in depth. Further, the authors suggest a shorter version of the BQ18 termed "BQ13" with stronger reliability. The current study also examines the utilization of the "BQ13" as a unidimensional scale. The authors discuss the positive outcomes of having a new scale to measure mental boundaries that are more up-to-date and can be utilized not only in research settings but clinical settings as well.
