does this trend have to do with the energy released when an electron is added to an atom?

Electron Affinity is the energy change when a neutral atom attracts an electron to become a negative ion. So yes you are, in a way, correct

Yes, but it has to be the energy released after adding an electron to a neutral atom.

Yes, and electron affinities are highest towards the right of the periodic table. To add on, a positive electron affinity means that that energy is released when an electron is added onto an atom. When energy must be used to add an electron onto an atom, that means that there is negative electron affinity.
