Subjective well-being simplify scale in college students: development, reliability and validity

Objective To develop subjective well-being simplify scale(SWBSS), and examine its reliability and validity. Methods A self-report SWBSS containing 13 items was developed on college student and research literature. 2374 college students completed SWBSS, Index of Well-Being(IWB), World Health of Organization Quality of Life Brief Scale(WHOQOL-BREF), Beck Depression Rating Scale(BDI) and Self-rating Anxiety Scale(SAS). Results ①Exploratory factor analysis results showed that SWBSS had 1 factor, and accounted for 41.768% of variance.②Confirmatory factor analysis results indicated that χ2/df=2.208, RMR=0.016, RMSEA=0.032; GFI=0.986, AGFI=0.974, NFI=0.978, RFI=0.966, IFI=0.988, TLI=0.981, CFI=0.988; PGFI=0.552, PNFI=0.639, PCFI=0.646; construct reliability=0.901. ③The Cronbach'α coefficient, split-half reliability, stability coefficient of SWBSS was 0.876, 0.817 and 0.740(P<0.01). The SWBSS scores was significantly correlated with the scores of IWB, WHOQOL-BREF, BDI and SAS(r=0.706~0.892, r=-0.650~-0.580, P<0.01). Conclusion The stability, internal consistency, and validity of the SWBSS are good and meet with psychometric standard.
