^aHigh category defined as >4.0 on 1–5 scale.

^bAdjusted for all other construct variables.

^cHow likely an unimmunized child in Wisconsin is to acquire vaccine-preventable diseases on 5 point Likert scale (very unlikely to very likely)—mean of 12 diseases.

^dOdds Ratio P<0.05.

^eHow serious it would be if an 8-year-old child acquired vaccine-preventable diseases on 5 point Likert scale (not at all serious to very serious)—mean of 12 diseases.

^fHow protective vaccines are on 5 point Likert scale (not protective at all to very protective)—mean for 6 vaccines.

^gHow safe children’s vaccines are on 5 point Likert scale (very unsafe to very safe)—mean for 6 vaccines.
