	HL
	Functional HL		Communicative HL		Critical HL
	β	p	β	p	β	p
Model 1	0.155	0.015	0.558	< 0.001	0.451	< 0.001
Model 2	0.176	0.011	0.503	< 0.001	0.429	< 0.001
Model 3	0.172	0.011	0.479	< 0.001	0.426	< 0.001

Model 1: unadjusted.

Model 2: adjusted for age, sex, education, economic status, Internet use, social support, time since the diagnosis of diabetes, number of oral glucose-lowering drugs, insulin use, and diabetic complications.
