Table 7.
Summary results (mean scores and standard deviations) for two subgroups exposed to an educational intervention (IG1 and IG2) for pretest and posttest at 8–10 weeks where only one subgroup (IG2) had a reminder at midpoint
| Groupsa | Pretest Mean (SD) | Posttest Mean (SD) | Change Mean (SD) | 95% CI | p Value |
|---|---|---|---|---|---|
| IG1 (n = 17) | 5.412 (1.33) | 4.765 (1.52) | 0.647 (2.06) | −0.33 to 1.63 | |
| Percent change | −11.9% | p = .043 | |||
| IG2 (n = 14) | 4.786 (0.89) | 5.571 (1.02) | 0.785 (1.53) | −0.92 to 1.59 | F = 4.486 |

a
Includes respondents who completed both pretest and posttest. IG, intervention groups (IG1, subgroup unexposed to reminder but undergoing a posttest at 8–10 weeks; IG2, subgroup exposed to reminder at midpoint and to a posttest at 8–10 weeks); n, number of participants completing the competency tests; SD, standard deviation. A higher score at the posttest indicates performance improved over time.
