Hi Linda, Good question. We made a video about some different programming options for multi-language studies that may answer some of these questions, you can watch it here: https://sawtoothsoftware.com/resources/videos/multi-language-surveys-lighthouse-studio-discover
If you have quotas (e.g. if you want 500 males, regardless of the language they speak), it may be easiest to use the second method I describe in the video: using code to integrate the four languages into the same survey. If we use code, all our respondents would take the same survey (therefore making quota control easy), we would just change the language that is displayed.
Otherwise, if you want 500 males from country 1, 500 males from country 2, etc. you could have a separate survey for each language. Either option would work - it just depends on the quota behavior you need.
If you have further questions about multi-language surveys after watching that video, feel free to reach out to our team at firstname.lastname@example.org or call our office at +1 801 477-4700.
