Retention of knowledge and acceptance change 15 months after the PD intervention. Left column (results from complete MATE, complete CINS, and two ACORNS essay items): pre- and post-test mean scores, n = 28 (100% participation). Right column (results from complete MATE, partial CINS, and one ACORNS item): pre-, post- and delayed post-test, n = 20 (>70% participation); Error bars represent standard errors of the mean. A shorter version of the post-test was used to increase the likelihood that participants would complete the survey. Note that the pre-post results for the full and partial instruments show similar patterns. See text for instrument details and scoring.
