Participant Flow

We facilitated report-back training workshops, including two in-person workshops at the International Society for Epidemiology (ISEE) and Partnerships for Environmental Public Health (PEPH) conferences, and three virtual workshops. Participants were recruited through conferences advertising the workshops (e.g., during conference registration), and through emailing individuals directly from a list we compiled of NIH-funded environmental health researchers.

Participants were not assigned to an arm or group. Rather, for all individuals who participated in a report-back training program, we evaluated any shifts in participants perspectives on environmental health report-back and wiliness to report-back with pre- and post-tests.

PRIMARY outcome

Timeframe: Participants completed surveys before and after the training program.

Population: Only participants who completed both pre-and post-tests are included in the analyses.

Participants ranked how strongly they agreed with each statement using a Likert-scale from 1 (strongly disagree) to 5 (strongly agree).

PRIMARY outcome

Timeframe: Participants completed surveys before and after the single-day training program.

Population: Only participants who completed both pre-and post-tests are included in the analyses.

Participants ranked how strongly they agreed with each of 3 statements about concerns about report-back using a Likert-scale from 1 (strongly disagree) to 5 (strongly agree). Responses were summed together to calculate sum concern (3-15). Higher values indicate greater concern about report-back so a higher post-test score would indicate a worse outcome (i.e., that concern about report-back increased as a result of the training program.

PRIMARY outcome

Timeframe: Participants completed surveys before and after the single-day training program.

Population: Only participants who completed both pre-and post-tests are included in the analyses.

Participants ranked how strongly they agreed with each of 5 statements about perceived benefits of report-back using a Likert-scale from 1 (strongly disagree) to 5 (strongly agree). Responses were summed together to calculate sum perceived benefits (5-25). Higher values indicate stronger agreement with perceived benefits, so a higher post-test score would indicate a better outcome (i.e., that perceived benefits of report-back increased as a result of the training program).
