Correction to: Subst Abuse Treat Prev Policy (2018) 13: 2. https://doi.org/10.1186/s13011-017-0139-9 Following publication of the original article [1], we have been notified that some data in the text should be changed.

Now it reads:

LMMs were used to examine the group differences in patterns of change over time (Table 2). Results of the LMM analysis showed that the intervention group made nonsignificant improvements compared to the compari-son group after the main intervention in terms of the scores of stress management (β =2.41, t = 1.81, p = 0.073), refusal skills (β =0.61, t = 0.62, p = 0.534), pros of drug use (β =0.97, t = 0.38, p = 0.703), cons of drug use (β =0.68,t = 0.25, p = 0.802) and drug use resistance self-efficacy (β =0.64, t = 0.51, p = 0.609). However, after the booster intervention, the participants of the interven-tion group showed significant improvements compared to their counterparts in the comparison group. There was a significant group × time interaction for the four outcome measures except for cons of drug use (β =3.98, t = 1.45, p = 0.150). The intervention group showed an increase in the score of stress management as compared to the comparison group after the booster intervention (β = 7.35, t = 5.19,p < 0.001). Similar patterns of between-group differences were found in the scores of refusal skills and drug use resistance self-efficacy (β =2.09, t = 2.10, p = 0.038;β = 3.47, t = 3.15, p = 0.002). The intervention group showed a decrease in the score of pros of drug use as

compared to the comparison group after the booster inter-vention (β = − 7.96, t = − 2.62, p = 0.010).

However, after the booster intervention, the participants of the intervention group showed significant improvements compared to their counterparts in the comparison group. There was a significant group × time interaction for the four outcome measures except for cons of drug use (β =3.98, t = 1.37,p = 0.174). The intervention group showed an increase in the score of stress management as compared to the comparison group after the booster intervention (β =7.35, t = 4.87, p < 0.001). Similar patterns of between-group differences were found in the scores of refusal skills and drug use resistance self-efficacy (β =2.09, t = 2.10, p = 0.038; β = 3.47, t = 3.09, p = 0.003). The intervention group showed a decrease in the score of pros of drug use as compared to the comparison group after the booster intervention (β = − 7.96, t =− 2.41, p = 0.017).
