CodeFull Text
C-BW-c-sq-m-11-aSelfreport on single question:

"To indicate how you feel about your life at this time, would you use this card? Suppose the top of the mountain represents the best life you can imagine, and the bottom step of the mountain represents the worst possible life you can imagine. On which step of the mountain would you say you personally feel you stand at this time? - assuming that the higher the step the better you feel about your life, and the lower the step the worse you feel about it. Just point to the step that comes closest to how you feel"
