Waddell's Signs, Nonorganic Signs
Why it Matters?
Waddell signs are frequently overstated in litigation, and the original authors have publicly objected to their use as evidence of malingering. The signs were developed to identify patients needing psychological evaluation alongside physical treatment, not to detect deception. Presenting them as proof of fabrication invites effective cross-examination using the authors' own statements, while presenting them accurately as indicating a nonorganic component is defensible.
