German to English Social Sciences Psychology mindfulness meditation

Sorry to break the "only one term" rule, but it's the whole concept that I'm not sure about. The phrase above is abbreviated from this:

"Die im vorherigen Abschnitt dargelegte Befundlage verdeutlicht den wirkungsvollen und vielversprechenden Einsatz der Achtsamkeits- und Mettā-Meditation in der Behandlung von Depression und lässt den Schluss zu, dass diese meditativen Techniken an zentralen Schlüsselstellen der depressiven Erkrankung, den kognitiven sowie motivationalen Aspekten, ansetzen."

It seems to me that something's missing, that there needs to be a "sollten" or "können" or something there, to yield my draft translation:

"The findings presented in the previous section illustrate the effective and promising use of mindfulness and Mettā meditation in treatment of depression, and suggest that these meditative techniques be applied at key points of the depressive disorder, to the cognitive as well as the motivational aspects."

Any advice?
