Въпросник за безпокойства на Щатския университет на Пенсилвания (PSWQ) – психометрични данни в българска юношеска извадка
Psychometric data of the PSWQ in Bulgarian nonclinical adolescent sample

Summary/Abstract: The data were obtained on 972 high school students (from 8th to 12th grade) – 286 boys, 670 girls and 16 missing. Exploratory factor analysis (PCA) extracts two traditional PSWQ factors (eugen value>1): Worry engagement and Absence of worry. Testing the two-factors model by confirmatory factor analysis (LISREL 8.72, ML-method) however suggests that second factor is determined by items formulations, e.g. the PSWQ appears to measure a single unitary construct, but response patterns differ between positively worded and reverse-scored items factor. The Worry engagement and PSWQ total score have acceptable internal consistency (Cronbach´s alpha 0,92 and 0,89). The PSWQ validity is supported by measurement and structural models of other self-description scales for: obsessions and compulsions (PI-BG, OCI-R), obsessive beliefs (OBQ-27) and thought suppression (WBSI). The paper also discusses sex and age differences as well as the Bulgarian adolescent norms. Results substantiate the use of PSWQ as research and assessment tool with adolescents.
