Note. REF = Reference category in logistic regression analysis. OR = odds ratio. CI = confidence interval.

^aCompleted some grade school, middle school, and/or high school.

^bScores ranged from 1–4 with higher values indicating greater endorsement.

^cTo assess whether the adolescent received the influenza vaccine within the past two years we consulted both the adolescent’s medical record and the state immunization registry (Florida SHOTS).

^dObtained from the adolescent’s medical record. To the best of our knowledge, none of the chronic medical conditions were contraindicated for HPV vaccination.

^eBaseline visit was a well-child visit vs. some other type (e.g., immunization visit, follow-up visit).

^fSelf-reported by the adolescent.

^*p ≤ .05;

⁺p ≤ .10.
