Thanks for you answer, Karissa. I think phrases like 'mental health', 'healthy behavior', and 'good way of living' should be ultimately related to pleasant states of mind. For example, taking some drugs isn't deemed healthy because, though pleasant temporarily, it may produce much more suffering later -- for the person, society, or even later generations. So I think prediction is very important.

<p>Erich Fromm in his <em>The Sane Society</em> (1955) argued that mental health should not be defined merely in terms of the person's harmony with his/her society.

Maybe a better/related question to ask is 'why?' AFAIK, it has all to do with being able to function without problems in current society. By definition, mental 'health' is defined by expectations from society. But, as you highlight, society changes over time. But, I will eagerly await an answer by someone within the field.

How can they? To be cynical, they can because there's no one better positioned to do so. (That and money, power that comes with prestige etc.) And by the way, it's [psychiatrists who do that](https://www.nytimes.com/2012/05/12/opinion/break-up-the-psychiatric-monopoly.html), in the US at least. So this is not a real question to be answered from psychology or neuroscience in my view.

@Fizz - *Mental health* and related terms have definitions which span all fields within the mental health profession.

We can return the question: when start 'non-healthy' state? Maybe, when the person complains or when is no longer 'fit' to live in his environment (which explains why healing can be done by modifying the environment)

I am going to close this question as both too broad, and opinion-based.  I believe the comments thus far support this reasoning.  How mental health is defined and assessed is complex, and certainly not done unilaterally by psychologists - it involves politics, history, culture, patients, clinicians, and researchers in various fields.

@ArnonWeinberg, where should I ask what the definition of 'mental health' is? Shouldn't a clinical psychologist be able to define his own field? By the way, I think almost all psychology is opinion-based to some degree. That's why there are different schools in psychology. It's not a hard science.

@Fizz, The fact that the American Psychiatric Association has created a famous classification of mental disorders doesn't mean that these conditions aren't psychological!

Not sure I follow @Arham.  Questions about definitions are certainly on-topic here, so feel free to ask about the definition of mental health, although I would not be surprised if this has already been asked (eg: https://psychology.stackexchange.com/q/19730/7001, https://psychology.stackexchange.com/q/10632/7001).  Clinical psychologists are trained to diagnose mental disorders, and can surely recite definitions, but they do not define (establish the criteria for) mental health on their own.

How can psychologists define 'mental health' when we know quite little about complexities of human life?
