Calculating statistical significance in behaviour change
This answer should provide a reasonable discussion of how to compare the two results for statistical significance.

We have n1 = n2 = n3 = 158. We have p1 = 128/158, p2 = 67/158, and p3 = 64/168. Just run the hypothesis test on each pair to see if there is a significant shift.

However, there is a bigger issue here. This question should have been answered before you started collecting data. The first thing you should be doing is coming up with your theory to test. Then you design your experiment. And only then should you be collecting the data, unless your goal is just to collect large amounts of data for future theory testing, which does not seem to be the case here (Best Research Practices).
