Model Description	χ²	DF	GFI	NFI	CFI	IFI	RMSEA	Δχ²
Model1: Hypothetical mediation model	238.01	85	0.948	0.956	0.971	0.971	0.056
Model2: Deletion of path from SM to QOL	259.05	86	0.943	0.952	0.968	0.968	0.059	21.04***
Model3: Deletion of path from SM to QOL and from SM to FPG	280.17	87	0.939	0.948	0.964	0.964	0.062	42.16***
Model4: Deletion of path from SM to FPG	273.97	86	0.940	0.950	0.965	0.965	0.062	35.96***
Model5: Alternative model: SS, SM, and FPG directly affect QOL	384.57	88	0.914	0.929	0.944	0.945	0.077	146.56***

DF = degrees of freedom; GFI = goodness-of-fit index; NFI = normed-fit index; CFI = comparative fit index; IFI = incremental fit index; RMSEA = root mean square error of approximation; SM = self-management behavior; SS = social support; QOL = quality of life; FPG = fasting plasma glucose
