Background/Aim. Measuring the quality of life (QoL) is vital in daily clinical practice because it shows significant information in addition to symptoms. There are a large number of scales for assessing the QoL. The Brunnsviken Brief Quality of Life scale (BBQ) measures importance-adjusted satisfaction across six life areas. A validation study of the BBQ scale showed good questionnaire features (high concurrent and convergent validity, internal and test-retest reliability, and sensitivity to change). Therefore, the BBQ scale is excellent for use in psychiatric patients to measure outcomes, as well as for everyday screening. Methods. This prospective cross-sectional study was performed among the final-year students in five high schools in Kragujevac, Serbia. Students completed the BBQ questionnaire. Statistical analysis was performed using a standard statistical method for scale validation and standardization. Results. Our study showed that the BBQ scale had high internal consistency (Cronbach’s alpha = 0.687). That result showed that the scale had good reliability in our study. The average BBQ score was 69.63 ± 16.70 (male: 69.66 ± 18.46; female: 69.83 ± 15.78, p = 0.944). Conclusion. The Serbian version of BBQ satisfies all the criteria of successful validation. Therefore, this scale can be helpful in assessing the QoL in the healthy youth population in Serbia. [ABSTRACT FROM AUTHOR]

Uvod/Cilj. Merenje kvaliteta života (KŽ) je veoma važno u svakodnevnoj kliničkoj praksi, jer pored simptoma pruža značajne informacije. Postoji veliki broj skala za procenu KŽ. Kratka Brunnsviken skala o KŽ (BKŽ) meri zadovoljstvo u šest životnih oblasti. Validaciona studija BKŽ skale je pokazala dobre karakteristike upitnika (visoku konkurentnu i konvergentnu validnost, visoku internu pouzdanost i pouzdanost ponovnog testiranja i osetljivost na promene). Zbog toga je upitnik BKŽ odličan za upotrebu kod psihijatrijskih bolesnika za merenje ishoda lečenja, kao i za svakodnevni „skrining“. Metode. Prospektivna studija preseka sprovedena je među učenicima završnih razreda pet srednjih škola u Kragujevcu, Srbija. Učenici su popunili upitnik BKŽ. Statistička analiza izvršena je korišćenjem standardne statističke metode za validaciju i standardizaciju skale. Rezultati. Naša studija je pokazala da je skala BKŽ imala visoku internu konzistentnost (Cronbach-ov alfa = 0,687). Takav rezultat je pokazao dobru pouzdanost skale u našoj studiji. Prosečan skor BKŽ bio je 69,63 ± 16,70 (muškarci: 69,66 ± 18,46; žene: 69,83 ± 15,78, p = 0,944). Zaključak. Srpska verzija BKŽ zadovoljava sve kriterijume uspešne validacije. Zbog toga, ta skala može biti korisna za procenu kvaliteta života populacije zdravih mladih osoba u Srbiji. [ABSTRACT FROM AUTHOR]
