Abbreviations: CH, choice group; EX, expert group; CO, comparison group.

Note. All means are unadjusted. Intention measured from 1 (low) to 5 (high); self-efficacy measured from 1 (low) to 4 (high); commitment measured from 1 (low) to 5 (high); difficulty measured from 1 (very) to 5 (not at all).

P ≤ .05;

P ≤ .01.

Numbers vary slightly due to missing data across outcomes.

Regression coefficients from linear regression models; for each outcome variable, the top row presents unadjusted values; the bottom row presents values adjusted for age, education, and race.
