Results from the blood donor competence, autonomy, and relatedness enhancement (blood donor CARE) randomized trial.

ABSTRACT:

Background

This study aimed to promote competence, autonomy, and relatedness among first-time whole blood donors to enhance intrinsic motivation and increase retention.

Study design and methods

Using a full factorial design, first-time donors (N = 2002) were randomly assigned to a no-treatment control condition or to one of seven intervention conditions designed to promote donation competence, autonomy, relatedness, a combination of two (e.g., competence and autonomy), or all three constructs. Participants completed donor motivation measures before the intervention and 6 weeks later, and subsequent donation attempts were assessed for 1 year.

Results

There was no significant group difference in the frequency of donation attempts or in the number of days to return. Sign
