I was really nervous for my psych eval...It turned out to be fairly easy...A straight forward questionairre about feelings, moods, and stress levels about certain aspects of life, work, family, etc. It also seemed like a screening for clinical depression as some of the questions I know from my limited background in college psych classes.
He did ask about sleep patterns, social situations, past/present drug/alcohol abuse, past or present history of depression or suicidal thoughts/attempts.
He asked about dieting history, body image, expectations of surgery, support system at home regarding surgery, etc..
I felt like maybe I was a bit too honest, with some of the direct questions he asked, but at the end he said I seemed like a very good candidate, and that he would forward the write-up of my eval to the surgeon.
I think if you are severely depressed/suicidal and not being treated for it, it can postpone surgery...basically, you need to be emotionally stable and ready for surgery. I think that many of us that are clinically obese may have some things that could be seen as "depressed", but when answering questions remember that psych is asking about your emotional state, not your physical state...
For example...I am physically exhausted from my weight and medical issues, but I'm not exhausted due to emotional reasons that is common with depression. I know that when I lose weight, I do regain a lot of energy and enthusiasm for activities... Now, if that isn't the case for you, the fatigue and exhaustion could be emotional..
Also I'm in pain a lot, so that limits my desire for social activities, that could be perceived as depression..but I was clear in telling the psychologist that I have pain and have had a rough year of illness.
Hope this makes sense... and for those that still have to take evaluation, just be honest, but keep it in perspective with what he/she is actually asking...If you are unsure, at any point, ask him/her to clarify the question...
Ultimately, they are there to help, and if you do need counseling or medicine, better now to find out, then down the road, while dealing with such a major life change that WLS brings.
Hope this helps....
