Visible effect definition
Visible effect means that the answer was plainly positive or showed dis- tinct motivation and already realized changes in the curriculum. “Some ef- fect” implies an answer that acknowledges the importance of tobacco edu- cation, but the school has nevertheless retained to the national curriculum. The “No effect” answers were simple and short: “no” (twice) or “not yet”. One of the reasons why the line between visible and some effect was difficult to draw was that some principals might have referred to the situation in gene- ral without paying attention to the HETIP intervention – this was difficult to deduce from the written answers.
