Total variance explained (R2): R2 for biospheric values = 0.416. R2 for environmental self-identity = 0.604. R2 for sense of obligation to reduce food leftover = 0.331. R2 for food leftover reduction intention = 0.536			Goodness-of-fit statistics: χ2 = 667.254 (df = 199, p < 0.001, χ2/df = 3.353), RMSEA = 0.082, CFI = 0.930, IFI = 0.930, TLI = 0.919
