| Templeman and Stinnett13 |
| Two questions were posed; an answer in the affirmative (i.e., any response other than zero) to either question resulted in the participant's being categorized as a frotteur for purposes of prevalence: |
| “How many times have you ever intentionally rubbed up (in a sexual way) against someone who did not know you, against his/her will in a crowd?” (a) 0, (b) 1, (c) 2–5, (d) 6–10 (e) 11–15,…” OR |
| “How many times have you intentionally touched with your hands (in a sexual way) someone who did not know you, against his/her will in a crowd? (a) 0, (b) 1, (c) 2–5, (d) 6–10, (e) 11–15” |
| Freund and Seto14 |
| Two questions were posed; an answer in the affirmative (i.e., a yes) to both questions resulted in the participant's being categorized as a frotteur for purposes of prevalence: |
