Results: Three-factor solution was extracted that explaining 71.373% of the total variance. Goodness-of-fit indices (GFI; χ(68) =332.037, < .05, χ/ = 4.882, GFI = .862, CFI = .928, NFI = .914, IFI = .928, RMSEA (90% confidence interval) =.091 [.081, .110]) in the final VEINES-QOL/Sym questionnaire structure demonstrated the adequacy of the three-domain structure.
