I agree with the 1st poster.
The study reported by you so far says nothing that other attention demanding endeavors cannot give the same or similar effect, for one.
But, more importantly, since the stimulus was superficial exposure to negative phenomenon, there is no testing whether the results are long lasting. That would be of decided value.
Temporary relief by distraction needs no study. That's in the public knowledge already.
But, that any game or similarly intensive activity, can have more than a temporary effect on actual trauma incurred in the arena or battlefield of life's journey, is not being tested here.
That which can achieve the above named goals so spuriously claimed, is noteworthy.
The study, as represented, is not.
