Which of the following could be classified as a non-medical source of evidence?

The identification of statements from the applicant's friends as a non-medical source of evidence is accurate because these statements provide insight and testimony about the applicant’s daily functioning, limitations, and overall situation but do not originate from medical professionals. Non-medical sources are valuable as they can offer perspective on how an individual’s condition impacts their life from the viewpoint of people close to them. Friends may describe behavioral changes, interaction levels, or struggles the applicant faces due to their condition, all of which can be relevant in evaluating disability claims.

In contrast, records from a treating physician, reports from a psychologist, and results from blood tests are all considered medical evidence because they come directly from qualified health professionals or medical tests. These sources provide clinical insights into the applicant’s health status and capabilities, which are central to the assessment process for Social Security Disability Insurance. Thus, the distinction lies in the origin and nature of the evidence—friend statements represent personal observations rather than professional medical assessments.
