Criteria for prioritization of HIV programs in Viet Nam: a discrete choice experiment

Table 4 Result of the discrete choice experiment on criteria for prioritizing the HIV response, main effect model together with interactions

Dependent variable (0 = if the basic profile is chosen; 1 = if an alternative profile is chosen)
	Main Effect Model		Model w/ Interactions
Criteria	β	std.err.	β	std.err.
Independent variables (coding under variables)
Δ Effectiveness	0.713*	0.328	5.482*	1.577
0 = no change, remains 4 million years of life saved
1 = increases, 5 instead of 4 million years of life saved
Δ Cost-effectiveness	0.240	0.296	0.184	0.317
0 = no change, remains $6 return for every $1 invested
-1 = decreases, $5 instead of $6 return for every $1 invested
Δ Sustainability	1.309*	0.336	1.377*	0.583
0 = no change, spending increases and then decreases
-1 = changes to spending constantly increases
Δ Treatment/Prevention	0.780*	0.312	1.486*	0.466
0 = no change, greater investment in prevention
-1 = changes to greater investment in treatment
Δ Feasibility	1.980*	0.327	3.190*	0.616
0 = no change, remains low feasibility
1 = increases, high feasibility instead of low feasibility
Constant	0.887	0.669	0.724	0.709
Interaction Terms (w/ Δ Effectiveness)
works in programming			−1.723*	0.563
involved in decision-making			−3.623*	1.457
Interaction Terms (w/ Δ Sustainability)
works in management			1.199*	0.539
responsible for decisions			−1.204*	0.590
Interaction Terms (w/ Δ Treatment/Prevention)
works in management			−1.156*	0.512
Interaction Terms (w/ Δ Feasibility)
responsible for decisions			−1.412*	0.633
rho	0.491		0.522
pseudo r-squared	0.190		0.245
