New article in Psychiatric Times by Simon Dein FRCPsych,PhD. Here are the useful checkpoints.
Evidence suggests religious involvement is generally conducive to better mental health, and patients with psychiatric disorders frequently use religion to cope with their distress.
Religious attendance has been associated with decreased suicide attempts in the general population and in those with a mental condition, independent of the effects of social supports. Not all religious variables and beliefs are related to better mental health. Exclusivity and extreme behaviors might be problematic.
Religious delusions have been associated with poorer outcomes, poorer treatment adherence, and more severe course of illness in patients with schizophrenia.
A professional's moral stance should be neutral, with no attempt to manipulate the patients beliefs.
My note on this is : The exception to this would be therapists/doctors who work with specific populations ie: Christian, Jehovah Witness, Indigo/Crystal. Or where the parents give permission to use cultural/religious/spiritual/philosophical beliefs to help shape desirable behaviors/ideas in children.

New article in psychiatry journal Current Psychiatry (Jan 2010) notes new fathers have postpartum depression too. Not surprising since the newborn child takes up much of the time of both partners. Anger outbursts, reckless drivinng, feelings of worthlessness, guilt, impaired concentration, thoughts of suicide and death, irritability, increased infidelity, insomnia, sleeping too much, anxiety, depression, eating too much, eating too little are signs New Dads should watch out for. The hope is if this becomes common knowledge will seek out help for these problems. Men are less likely than women to seek help and the stigma needs to stop. Writing this article was one step in that direction.
