This one is particularly useful for initiating discussion with majority students who are about to go to a country where they will stand out visually (by virtue of economics, dress, skin color, etc.) from the locals.  As such, it's best used in pre-departure or shortly after arrival.  It's not validated for pre/post uses, although that, too, could be an interesting sort of post-experience discussion.

My co-leader and I used this at the mid-way point in a three-week program between two very different homestays. We had students fill out the chart then discuss in small groups what they felt was most salient about their responses. We then had a whole group discussion about potential shifts they might expect in the next setting and had everyone one share one strategy they had already used to manage particular stressors. Our goal was to use the activity both to help students recognize and name their feelings and to reinforce an asset-based mindset -- they already had successful strategies -- while gleaning ideas for additional strategies from each other.
