Trial Outcomes & Findings for Guardians Receiving Information Through Navigators (NCT NCT07147244)
NCT ID: NCT07147244
Last Updated: 2026-08-28
Results Overview
We will ask participants multiple choice knowledge questions related to oral health which we will average to create a composite knowledge score for each participant ranging from 0 to 100. A score of 0 means a participant got zero questions correct while a score of 100 meant a participant got all questions correct. We will average these composite scores across all participants for both groups to create mean scores ranging from 0 to 100, the higher the score the more questions participants answered correctly.

Participant milestones
| Measure |
Treatment: GRIN Course
Community health workers (CHWs) in the treatment group will complete the GRIN course online training program. They will engage with the training materials, apply learned concepts, and complete pretest and posttest assessments to measure changes in their knowledge, attitudes, intentions and self-efficacy.

Control
Community health workers (CHWs) in the control group will not receive access to the GRIN course training during the study period. They will receive information from the American Dental Association to review while also completing pretest and posttest assessments to allow for comparison with the treatment group.

OTHER_PRE_SPECIFIED outcome
Timeframe: From baseline to posttest (2 weeks)At both pretest and posttest, we will ask all participants the same multiple choice knowledge questions related to oral health, which we will average to create a composite knowledge score for each participant ranging from 0 to 100. A score of 0 means a participant got zero questions correct while a score of 100 means a participant got all questions correct. We will average these composite scores across all participants for both groups to create mean scores. We will then subtract pretest scores from posttest scores and average these changes for all participants. Higher scores mean higher gains from baseline to posttest.

Control
n=139 Participants
Community health workers (CHWs) in the control group will not receive access to the GRIN course training during the study period. They will receive information from the American Dental Association to review while also completing pretest and posttest assessments to allow for comparison with the treatment group.

Treatment: GRIN Course
n=135 Participants
Community health workers (CHWs) in the treatment group will complete the GRIN course online training program. They will engage with the training materials, apply learned concepts, and complete pretest and posttest assessments to measure changes in their knowledge, attitudes, intentions and self-efficacy.

OTHER_PRE_SPECIFIED outcome
Timeframe: From baseline to posttest (2 weeks)At both pretest and posttest, we will ask all participants Likert-type scale questions about attitudes towards conducting oral health outreach. Each rating will range from 1 to 10, with higher ratings representing higher perceptions of oral health outreach importance. We will average ratings from each question to create an average composite rating for each participant, then average these composite scores for both groups. We will then subtract pretest scores from posttest scores and average these changes for all participants. Higher scores mean higher gains from baseline to posttest.

Timeframe: From baseline to posttest (2 weeks)At both pretest and posttest, we will ask all participants Likert-type scale questions related to perceived self-efficacy with conducting oral health outreach. Each rating will range from 1 to 10, with higher ratings representing higher perceptions of confidence in providing oral health outreach. We will average ratings from each question to create an average composite rating for each participant, then average these composite scores for both groups. We will then subtract pretest scores from posttest scores and average these changes for all participants. Higher scores mean higher gains from baseline to posttest.
