blood donor retention and tests the efficacy of this new approach among first-time, Group O
donors.
In this study the investigators will recruit first-time Group O- and O+ donors four weeks
after their donation using the donor databases of New York Blood Center and Hoxworth Blood
Center. Eligible donors will be contacted via email and invited to participate in the study.
Interested donors will be randomly assigned to either the Intervention condition where they
will receive a motivational interview and implementation intention intervention phone call
or to the Control condition where they will receive a standard donor recruitment phone call.
Outcome measures will be assessed before and after the telephone contact using online
questionnaires, and donation attempts will be tracked for one year. The investigators will
use survival analysis to examine the effects of this intervention on retention during this
one-year follow-up. Path analyses will also be used to examine potential mediators of the
intervention effect. The investigators hypothesis is that donors who receive the
motivational interview and implementation intention intervention will have larger increases
in positive donation attitudes and perceived behavioral control which will contribute to
enhanced intention and donation attempts.
