Similar to heavy drinking, an AO by delay interaction emerged for the slope (β = −0.11, p = 0.03) but not for the intercept (β = 0.05, p = 0.19). Again, a longer delay was associated with larger increases in problems for the earlier AO sample (β = 0.22, p < 0.001) but not the later AO sample (β = 0.08, p = 0.18).
