Background: Psychological boundaries are defined as one's ability to distinguish various components of psychological life: conscious and subconscious, self and others. The Boundaries in the Mind concept by E. Hartmann belongs to the psychodynamic tradition and is implemented in the Boundaries Questionnaire, which assesses the thinness of one's psychological boundaries. Its shortest version (18 items) has been adapted in Russian but is a one-scale tool. The BQ-46 version, developed by D. Rawlings, consists of six subscales which allow for structural analysis.
Objective: The objective of this study was to develop a Russian version of the questionnaire based on the BQ-46 and analyze its structure in a Russian-speaking sample.
Design: The BQ-46 was translated into Russian and back. Data collection was arranged online. Three hundred eighty-seven (387) participants filled in the Russian version of the questionnaire. Two hundred ninety-six (296) of them also filled out four additional questionnaires for convergent validity assessment, and one hundred and one (101) subjects completed a BQ-46 retest.
Results: The Russian version of the questionnaire (referred to as BQ-33) consists of 33 items and is a five-scale measurement tool. Its subscales are generally in line with the original BQ-46 version by D. Rawlings. The BQ-33 demonstrated acceptable-to-good reliability and good test-retest stability (r = 0.86). The convergent validity of the BQ-33 was supported by associations with the respective psychological concepts. My findings supported the idea of boundaries getting thicker with age, along with some tendency for gender differences for particular subscales.
Conclusion: The study results supported the validity and reliability of the BQ-33 in a Russian-speaking sample. This tool can be used to measure psychological boundaries and assess their structure.
