Explanation
A. While replicating the study using adolescents from across the United States could provide broader generalizability, it may not be necessary if the goal is to investigate the effectiveness of other smoking cessation programs.
B. Surveying the adolescents' families to determine how many family members smoke may provide useful information but does not directly address the effectiveness of other smoking cessation programs.
C. Investigating the effectiveness of other smoking cessation programs is warranted based on the findings that Program A was more effective than Program B. This action allows for comparison with alternative interventions to determine the most effective approach for smoking cessation among adolescents.
D. Providing all smoking adolescents in the three high schools with Program A assumes that Program A is universally effective, which may not be the case. It is important to explore other options and consider individual preferences and needs when selecting a smoking cessation program.
