  • NS indicates not significant.

  • a P value of the mean difference between pretest and posttest scores for the intervention group only.

  • b P value of the mean difference between the pretest and posttest scores for the control group only.

  • c P value of the difference between the mean score differences for the intervention versus control group.

  • d Knowledge scores indicate percent correct responses for test (perfect score = 100).

  • e Confidence levels were measured on the scale: 1 = not at all confident; 2 = not confident; 3 = neutral; 4 = confident; and 5 = very confident.

  • f PP values are mean differences for which point values were defined as 1 = never, 2 = once or twice, 3 = 3 or 4 times, and 4 = ≥5 times.

  • g Adjusted to exclude PPs related to cultural competency (see “Methods”).
