One point I have....'Medical models' and 'Psychological models' are NOT mutually exclusive. Both work TOGETHER.
This board is made up of people with very personal stories about the illness, that is what you will get... and there is a huge value to hearing those experiences.
If you want more clinical data, try a search in PubMed.
PubMed home
Anyone who searches long enough will find the answer to validate their point of view but that doesn't mean it will be the outcome or is even true.
Best of luck!
