As a climber and mental health professional with lived experience I would say there is something unique about bouldering that is beneficial to mental health and is succinctly captured in the brief summary of the study:
"'Since rumination is one of the biggest problems for depressed individuals, we had the idea that bouldering could be a good intervention for that.' [...] Stelzer explained that bouldering has a number of other important characteristics that make it especially beneficial for the treatment of depression, namely that it helps boost self-efficacy and social interactions — both of which hold innate benefits for dealing with depression. "You have to be mindful and focused on the moment. It does not leave much room to let your mind wonder on things that may be going on in your life — you have to focus on not falling," Stelzer said. "Bouldering not only has strong mental components, but it is accessible at different levels so that people of all levels of physical health are able to participate," she said."

Of course other features will complicate the picture and it is by no means going to be a magic bullet, but the study opens up the possibility of more alternatives to drug treatments and psychotherapy that can often be difficult and counterproductive for some people. From a community perspective it would be wonderful to see the private spaces of climbing walls (private sector as opposed to exclusive) become part of the broader community landscape.
For me it is the 'in the moment' thing of climbing that I find so immersive and relaxing (ankle sprains, loss of skin, flappers and the fingers of perpetual pain are, in their own way, quite relaxing for me).
Of course there may well be contraindications: obsessive behaviour leading to a slight distortion in reality whereby walls, door frames and just about any structure over three meters is assessed for climbability. But the distillation of all potential problems in life to a grade and the mantra of "what could possibly go wrong" will surely offset any minor slide into climbing obsession!
