Why Is Direct-To-Consumer Marketing of Diagnostic Tests for Mental Illness

Why is direct-to-consumer marketing of diagnostic tests for mental illness and behavioral problems a dangerous practice?

B) The tests are not predictive of which psychiatric medications are most likely to be beneficial to a specific individual.
C) People using such tests may not receive professional counseling for interpretation of results and accurate risk assessment.
D) These tests are often misused by employers to support the dismissal of employees who express opinions that are different from those of the company.
