She has published a book and articles on the subject of patients being mis-diagnosed and over-medicated. Her publications brought her to the attention of a House Sub-committee who was investigating the harmful effects of psychiatric medications on children as it follows them into adulthood. Dr. Roberts was invited to testify in Washington DC as an expert witness before this House Committee on the damaging effects of mis-diagnosis and over-medicating of psychiatric patients.
