Beck’s Personality Beliefs Questionnaire: Evidence of Validity and Reliability of the Russian Version

“…The PBQ did not become as popular in clinical practice as MCMI or MMPI, but is a widespread practical tool that has been translated into many languages including Spanish, Norwegian, Polish, Brazilian Portuguese, Argentine Spanish, and Turkish (e.g., Aktas, Guriz, Alpaslan, Cavdar, & Orsel, 2015;Moretti, Trógolo, Dominguez-Lara, Conn, & Medrano, 2018;Hernández, Darío, Vasquez, & Semenova, 2015;Zawadski, Popiel, Praglowska, & Newman, 2017) and is used not only in clinical samples but also in healthy controls (Ryan, Kumar, & Wagner, 2015;Thimm, Jordan, & Bach, 2016), patients with functional and somatic illnesses (Taymur et al, 2015) and people with drug addictions (Albein-Urios, Martinez-González, & Lozano, 2014). Some reviews consider the PBQ as a relevant instrument for DSM-V as well (e.g., Bhar, Beck, & Butler, 2012).…”
