Table 1.

Numeric Score Assignments for Trust Scale.

Survey question	Response assigned a score of 0	Response assigned a score of 1	Response assigned a score of 2
Overall, I trust the information I receive about shots.	Agree, Strongly agree	Not sure	Disagree, strongly disagree
I am able to openly discuss my concerns about shots with my child’s doctor.	Agree, Strongly agree	Not sure	Disagree, strongly disagree
All things considered, how much do you trust your child’s doctor?	8–10, 10 represents completely trust	6, 7	0–5, 0 represents do not trust at all
In general, medical professionals in charge of vaccinations have my child’s best interests at heart.	8–10, 10 represents strongly agree	6, 7	0–5, 0 represents strongly disagree

Note. Scores from all four questions were summed for each parent, to create a scale ranging from 0, representing high trust, to 8, representing low trust. The scale was then dichotomized such that scores of 0 were considered trusting and scores of 1 or higher were considered less trusting.
