Objectives: China is the world's largest tobacco consumer and its adolescent smoking rate is increasing. Smoking interventions among high school students are limited. The aim of this study was to deliver and evaluate a brief theory-based smoking intervention in China, with a focus on anti-smoking cognitions. Methods: The intervention was based on the constructs of an extended theory of planned behavior and life skills training. Using class-level randomization sampling, 106 tenth graders from two high schools in Kunming, China received a four-session intervention; 101 students were assigned as control group members. Surveys were conducted at three time-points (1 week before the intervention, 1 week post-intervention, and 6 months post-intervention). MANOVA and latent class analysis were used to test the intervention's effectiveness and personal change trajectories over time. Results: The intervention failed to change smoking behavior, intention or willingness, but improved anti-smoking attitudes and perceived control over smoking. Skills showed a general enhancement, consistent with participants' qualitative feedback. Trajectories of smoking behavior, intention, and willingness all assumed two distinct but constant latent classes independent of the intervention. Conclusions: This study suggests that addressing attitudinal and control beliefs among adolescents and building on assertiveness via additional strategies in life skills such as appropriate refusal skills may be beneficial. The absence of a successful change in subjective norm should be a focus for future anti-smoking programs in China.
