The average raw difference summarizes the difference for each factor and is defined as the average difference in the unprotected sex percentages across the three waves between those with and without the factor. The results are sorted in order of the average raw difference (avg. diff.). Hedges’ g ≤ 0.2 is negligible, 0.2–0.5 small effect size, 0.5–0.8 medium effect size, ≥0.8 large. Emotional and physical abuse is limited to respondents over 18 due to mandatory reporting requirements: n = 385, 368, and 419 at waves 1, 2, and 3. The p value is from t test.
