Consider this description of an RCT: Espada and colleagues (2016) conducted a test of the efficacy of a smoking cessation program for adolescents in Spain. Prospective participants were recruited using a convenience sample, then randomly assigned to either a program condition or a control condition. The control condition consisted of adolescents placed on a waiting list for the program. Six months after the program, 8% of the program group had quit smoking, whereas no one in the control group had. This difference was statistically significant. After 1 year, 43% of the participants were available for follow-up data collection; this proportion was similar across both program and control conditions. Making explicit reference to the concepts of internal and external validity, highlight several potential strengths and weakness of this study. What will be an ideal response?
