son humeur est bien contenue

Something with "in control" strikes me as the clearest solution.

which I am not - she seems in control, she is not letting her emotions run away with her

There's a strong chance I'll overthink this one, as a neuroscientist and also as a trainee clinical psychologist, particularly as I'm doing a thesis on the regulation of emotion.

Mood can be described as subdued which can imply, depending on where you look, reduction, prevention, containment : http://dictionary.cambridge.org/dictionary/english/subdue but also control : http://www.merriam-webster.com/dictionary/subdue I also like "well-contained" although we more readily describe emotions than mood in that way. "Contenu" suggests something voluntarily, altho' not exclusively and that, for me, pleads in favour or "contain". I wld tend to see a mood as being subdued as something involuntary, or something not of the individual's choosing, the effect of some external factor. In context, we are told there is neither anxiety nor major depression. If these are present, these could act as external factors and subdue a mood. They are absent, so I think the idea is that the person appears to be fine and is calm, not surpressing emotions as absence of anxiety and MD.
