In reply to Bleu Monstad:
Agree with many of the comments above, generally very good questions. However I do feel that they were largely assuming that climbing would have a positive effect on these things, I guess that is the point of the research but I would have thought that if you were interested in the positive side you would also be interested in the negative side. I think the question about the effect on relationships was a good one but I felt that there could have been more in that vein. Some more ideas of the possible negative side of climbing:
Climbing as egotistical and harmfully competitive
Climbing as compulsive/addictive
Climbing as leading to a neglecting of family, friends, wider more productive socially useful pursuits
Climbing as stressful and exacerbating stress and unhappiness in other areas of life
Climbing as leading to feelings of inadequacy and frustration
Climbing as contributing to exhaustion/burnout
I'm sure there are more but this what I could come up with based on my own experience, friends and testimony from pro climbers. There have been times in my life when I think that climbing has had a overall negative impact on me but I’ve kept doing it out of compulsion.
