Question: "Congruent to Content" meaning

Hi all. Question here at my group practice about what "congruent to content" means in the Clinical Session Note affect drop down. Some folks interpret "content" as the session's content... as in the client's mood is congruent to what is discussed in the session (the content of the session). Some folks interpret it as meaning that the client's affect is congruent to a content (happy, positive) mood.

Would love any clarification others have. Thanks!
