Just as importantly, we should not be prejudiced to currently fashionable research just because its currently fashionable.
I'm not sure 'we' are talking about prevention, that's something of a presumption that discounts the potential importance of environmental factors I'm actually thinking we are actually mostly talking past each other about different things
By environmental factors I mean, for example, traumatic experiences, inconsistent and abusive relationships/parenting, as well as social catastrophes such as the collapse of systems of social order and social structures in failed states as happened in east Germany, as well as things like job loss, divorce, isolation, changes in daylength and exposure to light... things that we KNOW are important as effectors that drive dysfunction.
I think what we as people interested in people with mental disorders desire is to help people not suffer and lose out on fullest value of life because they experience dysfuntions of mental disorders.
It's not a question of focusing on prevention at all. It's about society and psychiatric research choosing to dismiss things for any of several reasons, the worst of which might include because 'they are old school and haven't produced profitable results in the past"
With reference to the article presented it's about the risks of ignoring things. Especially ignoring things we know are important... We know that environmental factors, such as parental and sibling abuse influence psychological development leading to dysfunction be it narcissitic disorders, borderline, phobias, compulsions etc. We know that environmental factors that change life circumstances following loss of job, geophysical and social catastrophes (sever storms, floods, earthquakes, fire, exposure to war and violence, etc) lead to dysfunction ranging from adjustment disorder to PTSD.
