I regularly speak and email with colleagues at other academic institutions, including foreign institutions. We discuss scientific issues of interest to us, and we often co-author papers together. These activities are not in furtherance of an NIH grant. Should I include these informal collaborations as Other Support?
Yes. When informal collaborations rise to the level of co-authorship on academic papers, you should disclose that activity as Other Support. You can list this activity as “informal collaborative activity with__,” listing the names of your collaborators.
