Harvesting the claim management benefits of emerging neuropsychological assessment practices David Fisher, Ph.D., ABPP, LP PsyBar, LLC 952-285-9000 www.psybar.com (C) PsyBar LLC 2008. All rights reserved. Part 1: Overall Concepts (C) (C)PsyBar PsyBarLLC LLC2008. 2008. AllAllrights rightsreserved. reserved. Basic IME preparation: Make certain you have all the information you need before deciding to conduct an IME including: Complete medical records Records of telephone interviews with the claimant, the employer, and the treating doctor(s) Relevant collateral contact information Performance reviews Attendance records and other work-related information are helpful. (C) PsyBar LLC 2008. All rights reserved. Information to gather prior to neuropsychological evaluation – All prior neuropsychological evaluations (Rarely from other countries other than Canada and England) – “Raw test data” and “raw test protocols” mailed directly from the past psychologist to the IME psychologist (C) PsyBar LLC 2008. All rights reserved. Information to gather prior to neuropsychological evaluation Relevant medical information such as neuroimaging studies, physicals… Past psychiatric/psychological treatment records (standards in other countries vary) (C) PsyBar LLC 2008. All rights reserved. Basic IME preparation: Write down all significant consistencies and inconsistencies in all documentation and telephonic correspondence. This might clarify issues, and will help you write questions for the neuropsychologist. (C) PsyBar LLC 2008. All rights reserved. Selecting the appropriate doctor: MD psychiatrists often particularly adept in evaluating claimants with largely biologically based mental disorders. These disorders include schizophrenia, bipolar illness, certain depressive and anxiety disorders and the impact of medications. (C) PsyBar LLC 2008. All rights reserved. Selecting the appropriate doctor: Neuropsychologists: Evaluate clinical psychological problems, and cognitive deficits. Generally 5 year doctoral degree, plus 2 years of training in neuropsychology, and then work supervision. (C) PsyBar LLC 2008. All rights reserved. Objective testing: Over a hundred years of research on objective psychological testing has demonstrated that it can measure skills and behavior more accurately than can the most skilled clinicians. (C) PsyBar LLC 2008. All rights reserved. Objective testing: As objective psychological assessment has progressed, national psychiatric and psychological assessment standards have increasingly acknowledged the importance of including objective psychological testing when assessing human behavior. (C) PsyBar LLC 2008. All rights reserved. Objective testing: The courts have also increasingly stressed the importance of objective assessment. Satisfying the courts’ demands is especially important to insurers and employers, when asked to demonstrate that the assessment was performed according to nationally recognized standards. (C) PsyBar LLC 2008. All rights reserved. Objective Testing: Used along with clinical judgment Helps you defend your claim determinations (insurers) and managerial decisions (employers).

The Great Divide He has either, a primary auditory verbal memory deficit originating in the hippocampal or mesio-hipppocampal area, or difficulty with processing efficiency! (C) PsyBar LLC 2008. All rights reserved. But, what can he DO? How to ask questions: Clear, concise questions will help you obtain the information you need to confidently support your claims decisions. (C) PsyBar LLC 2008. All rights reserved. How to ask questions: Before you write questions, clarify your goal. (e.g. do you need to determine causation, diagnosis, percent disability, truthfulness etc? ) (C) PsyBar LLC 2008. All rights reserved. How to ask questions: Avoid leading questions. Unintentionally, Independent Examiners might be influenced by leading questions and consequently offer biased responses. Even when Independent Examiners impartially answer leading questions, those responses are vulnerable to challenges during litigation. (C) PsyBar LLC 2008. All rights reserved. How to ask questions: Development of a standard set of referral questions. Minor variations in referral questions can result in major differences in Independent Examiners’ responses. (C) PsyBar LLC 2008. All rights reserved. Before you write your first question, understand doctors’ vs. insurers’ perspectives: “I don’t necessarily need to justify my conclusions with several kinds of evidence.” “As an insurer, I can be more confident in making decisions if there are several types of convergent evidence supporting my claims decisions.” (C) PsyBar LLC 2008. All rights reserved. Examples of referral questions: From a psychiatric/psychological perspective only, please respond individually to sections “a” through “e” below by describing this claimant’s current abilities and limitations in his/her ability to perform daily tasks. (Questions © PsyBar 2005 - 2008) Abilities and limitations in performing tasks secondary to psychological symptoms and abilities, as: a) reported by the examinee. b) observed before, during and after the examination. c) indicated by objective test data. d) documented in the medical record. e) documented by other means, such as with your collateral interview(s). © PsyBar, LLC 2005 - 2008 (C) PsyBar LLC 2008. All rights reserved. Referral question Please explain how your sources of evidence above are consistent or inconsistent with each other. For example, is the examinee self-report consistent with your observations and with test data? (Questions © PsyBar 2005 - 2008) (C) PsyBar LLC 2008. All rights reserved.

Part 2: Neuropsychological IMES: (C) PsyBar LLC 2008. All rights reserved. Neuropsychology: Includes the assessment of cognitive abilities with a combination of objective / actuarial procedures as well as largely subjective observations. (C) PsyBar LLC 2008. All rights reserved. Neuropsychological assessment used when: There is a trauma, injury or disease causing: – Obvious cognitive difficulties – Physical functioning (e.g. fatigue, perceptual problems) – Emotional functioning (C) PsyBar LLC 2008. All rights reserved. Neuropsychological assessment used even if: -neurological or other evaluations are not helpful (MRI,CT etc. show structure, not function). -there is no gross impairment in cognitive functioning that would be obvious to a physician. (C) PsyBar LLC 2008. All rights reserved. A Good Evaluation will include: Extensive interview with the patient (2 - 31/2 hours) with an additional 4 to 10 hours of testing. Collateral interviews with spouse, employer, and / or others (C) PsyBar LLC 2008. All rights reserved. A Good Neuropsychological evaluation will contain a range of tests measuring: Intellectual abilities Memory Functioning Motor speed and coordination Naming skills & verbal fluency (C) PsyBar LLC 2008. All rights reserved. A Good Neuropsychological evaluation will also contain tests measuring: Attentional abilities Executive Processing speed Personality traits & mood Truthfulness, motivation and effort/malingering (C) PsyBar LLC 2008. All rights reserved. In a normal individual with no brain damage: the measurement of different cognitive abilities should result in test scores that are roughly equivalent to each other.

Psychological vs. organic problem Inconsistency from one evaluation to the next and problems worsen during times of emotional stress Inconsistency from one conceptually similar test to the next Pattern of deficits does not match those usually seen in an organic disorder (C) PsyBar LLC 2008. All rights reserved. Part 3: Validity (C) PsyBar LLC 2008. All rights reserved. Clinical Judgment/ “intuitional” perspective “I’ve evaluated thousands of patients over 30 years and I know a faker when I see one. Why do I need psychological tests?” (C) PsyBar LLC 2008. All rights reserved. Clinical Judgment/ “intuitional” perspective Myth: With an interview, a psychologist or psychiatrist, using many years of clinical knowledge, can consistently identify those individuals who are deceptive. (C) PsyBar LLC 2008. All rights reserved. Clinical Judgment/ “intuitional” perspective Fact: There is little, if any, credible evidence that experienced mental health professionals are able, across a variety of situations, to reliably identify deception using clinical judgment alone. (C) PsyBar LLC 2008. All rights reserved. Objective testing: Virtually always desirable for the psychologist or psychiatrist to rely in part on objective psychological test results to assess deception. (C) PsyBar LLC 2008. All rights reserved. Test of Memory Malingering 15 minutes long and requires claimant to remember simple drawings Claimants who are not putting forth full effort receives scores lower than those obtained by patients with genuine neuropsychological problems Correct classification rate is approximately 80% (C) PsyBar LLC 2008. All rights reserved. Validity Indicator Profile Sophisticated computer-scored test Cannot be used with individuals who are severely cognitive impaired Both verbal and visual portions Approximately 77% correct classification rate (C) PsyBar LLC 2008. All rights reserved. Word Memory Test Computerized 5-minute verbal and nonverbal are computerized memory test. Contains hidden measures, which serve to check the validity of the patient's test scores. Close to 100% accurate in classifying some simulators versus good effort volunteers (C) PsyBar LLC 2008. All rights reserved. Portland Digit Recognition Test (1991) Two-choice design, to select a previously administered string of 5 digits. Some people score below chance levels. Only identifies those whose deception is prominent. (C) PsyBar LLC 2008. All rights reserved. MMPI-II Revised throughout the 1980s Examines validity of reports of psychological disturbance (not specifically designed to evaluate truthfulness regarding neuropsychological dysfunction Evaluates areas such as depression, anxiety, attitude towards work and psychotherapy, tendency to report physical problems when under emotional stress, and self-confidence. (C) PsyBar LLC 2008. All rights reserved. When does it make sense to use more than one test to evaluate deception? When you need to rule out deception of both psychological problems (e.g. depression) and cognitive difficulties (e.g. memory problems). (e.g. MMPI-2 and TOMM) (C) PsyBar LLC 2008. All rights reserved. Determining deception by comparisons to prior scores: Person with brain injury: Scores show rapid recovery in first 4 months after injury. Recovery very slow after 1.5 years. (C) PsyBar LLC 2008. All rights reserved. Identifying deception with comparisons to prior scores: Suspicious patterns with brain injury: Scores drop during times when recovery should be taking place Scores don’t match the pattern of low scores that is predicted by the type of brain injury (e.g. people with injury to memory centers show deficits in many areas other than memory) (C) PsyBar LLC 2008. All rights reserved. Identifying deception (incl. defensiveness) by comparing test scores collected at different points in time MMPI-2 test scores during the Independent Medical Evaluation are much different than those obtained by treating doctors. (C) PsyBar LLC 2008. All rights reserved. Determining deception with unlikely patterns of scores across different types of tests Severely depressed people often have problems with more “effortful” memory tasks. While MMPI-2 scores suggest severe levels of depression, tests of “effortful” memory are strong. (Compelling but very difficult to support this approach though with research) (C) PsyBar LLC 2008. All rights reserved. How to request Specific Psychological Tests Very diplomatically Don’t tell the psychologist what to do Focus more on defining the problem to be answered and working with the psychologist about the best tests to use Very complex process, taking into consideration test validity/reliability, examinee age, sex, capabilities, etc. (C) PsyBar LLC 2008.
