The primary outcome is the self-reported smallest incentive amount (U.S. dollars) that would motivate participants to try and increase their HPV vaccination rates. We tested for differences across P4P designs using unadjusted responses and linear regressions adjusting for clinic and respondent characteristics. We also tested for heterogeneous responses by experience with incentizves, training, and rurality.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec014\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The mean amount required to motivate effort was $2,155 in the gain P4P design and $1,185 in the loss P4P design (unadjusted difference =\u2009 $970 [p\u2009&lt;\u20090.001], adjusted difference =\u2009 $967 [p\u2009&lt;\u20090.001]).
