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.

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. GRIN Course: Online professional development training for CHWs on outreach and support for guardians with children and adolescents
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.

We will average ratings from each question to create an average composite rating for each intervention participant, then we will average these scores across the intervention group. Scores ranged from 1 to 10, with higher scores meaning better satisfaction/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.

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 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.

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=136 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)

We will ask all participants Likert-type scale questions related to their intentions to conduct oral health outreach. Each rating will range from 1 to 10, with higher ratings representing higher perceived likelihood of providing oral health outreach in the future. 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.
