How does this study fit into the context of previous research examining the reasons behind adolescent smoking?
What’s different about this study is that rather than looking at what’s happening on average in a population, we asked the question in a way that allowed us to identify subgroups in a population. Specifically, we used a method known as classification and regression tree analysis. This method looks for possible relationships between an outcome – in this case, smoking – and a sequence or progression of factors that may have influenced the outcome, either together or separately. This method hasn’t been used very often in behavioral research, and, to the best of our knowledge, hasn’t been used at all in terms of substance risk research. Q: Why is it important to tease out subgroups when you’re looking at substance use behavior? A: I think that if you get any group of clinicians in a room, they would probably all agree that different people reach similar substance use outcomes in different ways. There isn’t one mechanism, or one theory, to explain how every single drug user or drug abuser g
