This outdated MRFC is used for training purposes only.  The principles behind using the RFC data in a disability claim are the same regardless of the form.  The MRFC or Mental Residual Functional Capacity form is used internally by Social Security to determine the type and severity of functional limitations caused by the claimant's mental impairment(s).  In your capacity as a disability advocate, you'll never actually fill-out an RFC form.  You refer to this form as a means of determining what mental limitations are most relevant to Social Security. 

The MRFC form is important because the mental limitations listed on this form are those considered by Social Security to have the greatest impact on a claimant's ability to perform work.  Work is action!  If the claimant is unable to perform at an appropriate mental capacity, he's also unable to perform work at that mental capacity!  Social Security considers certain signs and symptoms to be relevant than others.  Emphasizing what is most relevant to SSA is the easiest roadmap to winning every case you represent.  The form itself tells you what Social Security considers to be relevant mental restrictions.  The links below connect to the three most important pages of SSA's Mental RFC form.
