- Means and standard deviations (SD) for Unprotected Anal Intercourse (UAI)-change score (t2-t0) for insertive and receptive anal sex by study condition, steady relationship(SR)-status change (yes vs no) and sexual behaviour at pretest (safe vs unsafe)1.
-
1 ANCOVA adjusted for ethnic background (Dutch vs non-Dutch) and educational level (low level: elementary school, vocational school or lower-level high school; high level: university, college, or higher- level high school).
-
2 SR = steady relationship
- ** significant difference between experimental group and control group, P < 0.01
