Has anyone else had this via their GP? A research project that aims to create an evidence-based model for best practice for medication reviews. I was happily completing the online survey form - I'm very obedient and awfully willing to help - but unfortunately the survey wants to know my gender rather than my sex. I'd be perfectly at ease telling them both my sex and my gender (I believe both are of interest when data-gathering) but I'm not responding to anything health-related that is collecting information on 'gender' only. Sloppy research design. Any thoughts?
