This is taking a feeling and translating it to a feeling, value or need that is behind that feeling.
This is extensively explored in Nonviolent Communication (NVC). Where feelings are seen as the gateway to met or unmet needs. For example, the feeling anxious could be seen as a having a need for safety or acceptance. One problem with the NVC model I see it that needs have a felt experience. So you can say people have feelings which point to other feelings. For example safety or acceptance has a felt quality to it.
The Compassionate Listening Project say feelings point to values. So I'm feeling anxious about a situation because my value of fairness isn't being addressed.
