Forensic Evaluations
What Sets Us Apart
Expertise
Extensive experience in forensic psychology means we bring a wealth of knowledge to each evaluation.
Thorough
Our evaluations go beyond surface-level assessments.
We delve into the intricacies of each case, considering the unique factors that may influence the psychological well-being of the individuals involved.
Objectivity
Evaluations are utilized to assess whether there is the presence of a mental condition or, conversely, malingering or symptom exaggeration as a result of the alleged injury. We strive for an unbiased evaluation.
Application to Case Disposition, Trial and Settlement
Our comprehensive reports showcase the psychological aspects of the legal case and serve as invaluable tools in favorable settlements, which can spare the attorney’s clients the challenges of a lengthy trial.
If the case does go to trial, we are prepared and skilled to deliver our findings to a trier of fact.
Testimony
Articulating scientific principles for a lay listener is a skill developed on the stand and in deposition.
Our testimony is valued for our delivery of conclusions that are logical, well-founded and professional.
Compassionate Approach
We recognize the sensitive nature of the case and the parties involved. We approach evaluations with empathy and compassion without sacrificing objectivity.
Emotional Distress, Psychological Factors
Torts and Allegations
The role of a Forensic Psychologist is pivotal whether the alleged tort is intentional or negligent infliction of emotional distress, or an allegation appears unfounded.
Investigation and inquiry by a qualified expert witness can be of profound assistance to attorneys and courts.
Presence or Absence?
- Mental health injury
- Connection, if any, between the traumatic incident and the plaintiff’s psychological state
- The mental state of others who are involved, relevance
- Malingering
Diagnosis and Degree
A psychological assessment becomes crucial when determining eligibility for compensation due to psychological injuries.
We strive to discern whether the involved parties are genuinely experiencing the reported distress or if the injury might be attributed to unrelated stressors.
For example, a preexisting condition or unique vulnerabilities in an examinee may introduce complexity to valuing cost of future treatment.
Mental Status Factors: A Point in Time
Mental health or illness can reveal something about the behavior of parties at a point in time, such as the moment of an accident. The “point in time” can also be a discrete span, such as a period of undue influence or alleged abuse.
Ongoing mental illness can muddy the waters and we consider those complexities. Our focus is on understanding the psychological elements of a case.
In thousands of criminal competency cases we have been asked this question, but it is applicable to any case where competency is relevant and mental harm has consequences. Even one event can be life-changing. There can also be emotional fallout for the family of a person so affected.
Personal Injury and Civil Claims
Allegations of mental distress are examined in cases like these:
- Motor Vehicle Accidents
- Medical Malpractice, Breach of Standard of Care
- Harassment, Termination
- Slip and Fall and associated negligence claims
- Testamentary capacity and Probate
- Sexual Assault
- Workplace Accidents (not Workers’ Compensation)
The Cost of Damages
If liability is proven and a mental injury resulted, we consider the future impact and cost of plaintiff’s recovery. A psychological assessment becomes crucial when determining eligibility for compensation due to psychological injuries.
Impact on Settlement
In settlement negotiations, this cost is relevant even if liability is disclaimed as part of an accepted settlement.
Testimonials
“Dr. Vorwerk has testified for me on several cases.
Her credentials and expertise impress both judges and juries, but even more important, she knows how to make the most difficult concepts easy to understand.”
~ Attorney (name withheld by request)
“Dr. Vorwerk’s incredibly detailed, sympathetic, and insightful report on a recent federal case quite literally took years off my client’s sentence.
Her report was quoted by the Judge, and gave him the tools to depart from the guidelines.”
