Въпросник за безпокойства на Щатския университет на Пенсилвания (PSWQ) – психометрични данни в българска юношеска извадка

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 (eugenvalue>1): Worry engagement and Absence of worry. Testing the two-factors model by confi rmatory factor analysis (LISREL 8.72, ML-method) however suggests that the second factor is determinated by items formulations, e.g. the PSWQ appears to measure a single unitary construct, but response patterns differ between positively worded and reversescored 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 discusses also sex and age differences as well as the Bulgarian adolescent norms. Results substantiate the use of PSWQ as research and assessment tool with adolescents.
