I just love sharing info that I have so that the people in the mental
health profession aren’t the only ones with the knowledge.
So I found this info about this model from Mentalhelp.net
The article is longer than this. I just copied the opening paragraph.
When professional mental health clinicians are asked to figure out
what is wrong with a patient, they assess that patient broadly, using
something they call the “bio-psycho-social” model as a guide. The
bio-psycho-social model assumes that mental health problems are hardly
ever limited to just one domain of human experience (say, just a
“mental” problem). Instead, most mental health problems are influenced
by multiple domains of human experience, and have biological
(medical), psychological (mental) and social/spiritual impacts. For
instance, someone who is depressed, might have become that way because
of a medical condition (such as a heart attack), a social condition
(such as losing a loved one), or a psychological condition (such as an
overly self-critical nature). Further, regardless of the cause of the
condition, that person’s depression will likely show physical symptoms
(such as slowed speech and lessened appetite), psychological symptoms
(such as suicidal thoughts) and social symptoms (such as social
withdrawal). Perhaps most importantly, it is possible to treat
depression through physical means (anti-depressant medicine, physical
exercise), psychological means (cognitive therapy) and also social
means (urging the person to get out and interact with other people)
regardless of how that depression got started. All of these methods
are likely to prove helpful in lifting depressed mood. What is more,
they can all be used at once despite their different origins; you
aren’t limited to trying one intervention at a time.
