This research evaluates condom-use self-efficacy and its increase throughout
adolescence. Documentation of the development of condom-use self-efficacy would
be important for prevention efforts given the influence of self-efficacy on
actual condom-usage. This study assesses a hypothesized mediation mechanism of
the development of self-efficacy using a mediation analysis approach. The
participants, 497 grade-6 Bahamian students, were randomly assigned to the
control condition in a 3-year longitudinal HIV prevention program trial.
Condom-use self-efficacy consistently increased and condom-use self-efficacy
assessed at earlier periods was positively associated with its values at
subsequent periods. Additionally, self-efficacy assessed between two time points
one year apart or longer (e.g., 6 months between baseline and 12 months)
significantly mediated the impact of its levels at the previous assessment on the
level at the subsequent assessment. To sustain program effect, HIV prevention
programs should strive to enhance self-efficacy and provide reinforcing
"boosters" no later than 12 months post-intervention.
