I side with Blink, Cricket, Berserk2, Snoopy, and even Bundy is not so fubar on this one -
I really have a basic squawk about this study. Look at the findings - They're substantially tautological. The findings are defined by the terms of the question. - As a way to look at social issues, this might be an interesting article, but it is not very good science.

"Young men who held non-traditional religious views were at twice the risk of being more anxious and depressed than those with traditional beliefs." - Turn that around and we find that depressed and antisocial people are far more likely to have non-traditional beliefs that deviate from the society and popular religious thinking in general. - Nothng new here.
"This study suggests that new forms of religiosity demand further research attention to understand the extent that religious change is linked to population mental health and social behaviour among younger generations," Dr Aird said. - Here we have the question as to which is the cause and which is the effect. Do we have a sick population that is deviating from prior social values, or do the prior social values create tension that cause a sick population? It is important to discern which part is the tail and which part is the dog - or are these correlates that arise together?
"Dr Aird found only eight per cent of young adults attended church once a week, a trend linked to lower rates of antisocial behaviour among young men, but not females." - Here we can discover the uninteresting fact that people who are less antisocial engage in social activities more often, and females are less antisocial than men. - Aside from the obvious, that's a rough description of social roles.
"She said individualism was the common thread in the shift away from traditional religious thoughts to non-religious spirituality." - And here we are told that, in context of prior statements, individualism is the common factor found in anti-social people, and that these individualistic people shift away from the traditional religious practices of the greater society. - Yup, that's how we define individualism.
And now that I've demonstrated that my views are antithetical and individualistic, the assumption would be that I am anti-social, which is proven by failure to participate in an organized religion. On thast basis it seems to be time to roll out the Malleus Malificarum and start sending these non-believers to the dungeon where we can torture them until their morale improves. Where is the Inquisition when we need it?
