As noted by Roth et al. Behav Sci Law. It should be noted that in the preceding sentence, we intentionally used the term highest correlations rather than strongest correlations. The significance in the difference of magnitude of various correlations was rarely tested although there are established methods for testing the magnitude of differences between bivariate correlations (Cohen, Cohen, West, & Aiken, 2003). Arch Neurol. The phrase "decision-making capacity" refers to a potential participant's ability to make a meaningful decision about whether or not to participate. For example, Marson, McInturff, Hawkins, Bartolucci, Harrell, (1997) compared the healthcare decision making capacity judgments of five experienced physicians who watched videotaped competency interviews of 29 patients with mild Alzheimer's disease (AD) and 16 normal comparison (NC) subjects. Are clinician's ever biased in their judgments of the capacity of older adult's to make medical decisions. (2014). Assessment of Decisional Capacity Slides - Oregon Older Adult . Cognitive predictors of understanding treatment decisions in patients with newly diagnosed brain metastasis. Medical decision-making capacity in cognitively impaired Parkinson's disease patients without dementia, Movement disorders: Official journal of the Movement Disorder Society, Psychological assessment versus psychological testing. Unfortunately, the validity of unstructured determinations of capacity is problematic. Competency is a global assessment and a legal determination made by a judge in court. and transmitted securely. Neurocognitive deficits that are associated with some neuropsychiatric conditions. Marson DC, Earnst KS, Jamil F, et al. This assessment is the foundation on which medical providers may gain legal protection when acting against a patient's immediate wishes in the service of the well-being of the patient, the staff, or the overall public. Validity and reliability of Structured Interview for Competency Incompetency Assessment Testing and Ranking Inventory. Instruments for assessing decisional capacity, Unaided by structured methods, there tends to be low interrater reliability among clinician judgments of decisional capacity.10,11 Fortunately, interrater reliability can be improved with specific guidance on the standards for decisional capacity,12 and a number of structured or semistructured instruments have been developed to assist clinicians to systematically evaluate their patients' decisional capacity relative to such standards.13-15, In a recent comprehensive review we identified 15 published questionnaires or instruments that assess capacity to consent to treatment (as well as 10 instruments for assessing capacity to consent to research).13 Nine of the 15 treatment consent capacity measures provide for assessment of all 4 dimensions of decisional capacity, and evidence of at least adequate interrater reliability (= 0.80) was available for 7 of these 9 measures (Table).13. We have provided two prior comprehensive reviews of this empirical literature (Palmer & Savla, 2007; Palmer, Savla, et al., 2012). "Capacity" refers to a patient's mental ability to participate in decision-making, can wax and wane, and is determined by healthcare providers at the bedside. The latter is a decision made by the court, not the clinician. It is therefore crucial that we understand how clinical judgments of decisional capacity relate to the social dynamics of decision making. Moye J, Gurrera RJ, Karel MJ, et al. Similarly, a cognitively impaired person may lack capacity to consent for treatment when the procedures or the risk:benefit considerations are complex but may retain sufficient capacity to consent to a simple/straightforward and/or low-risk treatment decision (Appelbaum & Grisso, 1988). Finally, to make and express a choice, one must be able to disengage from information processing and actually come to a conclusion. The key for the psychologist or other clinician conducting a capacity evaluation is to consider the specific item content in light of the presenting question and whether that content is relevant to the targeted ability being assessed. 1977;134:285-289.8. Decisional capacity to consent to research among patients with bipolar disorder: Comparison with schizophrenia patients and healthy subjects, Relationship of individual cognitive abilities to specific components of decisional capacity among middle-aged and older patients with Schizophrenia. Moved Permanently. For example, for a person experiencing a severe depressive episode, the relevant question would not be his/her ability to make decisions in general, but something akin to whether to consent to electroconvulsive therapy, pharmacologic treatment, psychotherapy, hospitalization or outpatient treatment, refusal of any active treatment, or some combination of such options. Schema theory is a notion from the broader psychological literature (supported by substantial empirical data), which suggests that a preexisting body and structure of relevant knowledge generally facilitates less effortful processing of new information, making it less dependent on active/limited information processing resources (Bransford & Johnson, 1972; Norman & Shallice, 1980; Schank, 1980). da Silva R., Mograbi D. C., Silveira L., Nunes A., Novis F. D., Landeira-Fernandez J., et al. Brain metabolic correlates of decision making in amnestic mild cognitive impairment, Assessing competence to consent to treatment: A guide for physicians and other health professionals, MacArthur Competence Assessment Tool for Treatment (MacCAT-T). Under the four-component model of decision-making capacity reviewed earlier, reasoning is generally conceptualized as the presence of reasoning processes, such as the ability to envision and compare potential consequences of various options (Grisso & Appelbaum, 1998a; Roth et al., 1977). Ideally, the content of the initial and scoring criteria for such questions can themselves be standardized.26 Based on the response to such initial inqui-ries, the need for more comprehensive assessment may become apparent. One important caveat regards the distinction between assessment of capacity and a competency determination. Eyler LT, Jeste DV. Moye J., Gurrera R. J., Karel M. J., Edelstein B., & O'Connell C. (2006). In other words, we suspect that in actual application, the issue of consent capacity tends to be discussed explicitly not so much in terms of capacity to consent but capacity to dissent/refuse treatment. Edelstein B. Hopemont Capacity Assessment Interview Manual and Scoring Guide. Among the various forms of civil consent capacity, healthcare consent capacity is important for the primacy to which it directly affects the right to decide what happens to one's own body. Of note, recent research suggests that it may be important to not only attend to level of cognitive impairment but also to intra-individual variability in neurocognitive test performance. For example, the use of multimedia consent aids has not yet proven consistently effective in research contexts (Palmer, Lanouette, & Jeste, 2012), but computerized decision aides in treatment contexts have garnered more empirical support. The answer in part lies in a complete and thorough assessment of a patient's capacity for medical decision-making. Assessing decisional capacity for clinical research or treatment: A review of instruments. Conceptualization and executive function measures are important to consent capacity because of their relevance to organized processing of treatment information. PDF Assessment of Decisional Capacity Slides - Oregon Older Adult Multiple different tools have been developed to aid in capacity assessment. Marson DC, Ingram KK, Cody HA, Harrell LE. 1997;48:1415-1419.20. Marson D. C., McInturff B., Hawkins L., Bartolucci A., & Harrell L. E. (1997). Sullivan K. Neuropsychological assessment of mental capacity. Alvarez M. I., Ban P. B., Navo A. M., Lopez-Anton R., Lobo E. E., & Ventura F. T. (2014). We compared different methods of capacity assessment, current research and the validity of different methods. Agreement between instruments for rating treatment decisional capacity. Thus, reasoning may draw on both working memory (to keep the information in active awareness/consciousness), and various executive functions such as abstraction, and planning or foresight for envisioning consequences. Decisional Capacity Determination in Patients With Cancer The influence of intra-individual factors, such as fatigue, anxiety, as well as more stable but potentially malleable factors such as health literacy should also be considered. Therefore, multimedia tools appear to hold promise as an effective supplement to the way patients receive and process clinically important information. II: Measures of abilities related to competence to consent to treatment. Sessums L. L., Zembrzuska H., & Jackson J. L. (2011). II: measures of abilities related to competence to consent to treatment. Arch Gen Psychiatry. 2006;26:1054-1077.15. The above four-component model of capacity is not without its critics. Medical decision-making abilities in older adults with chronic partial epilepsy. (Ed. The Cornell-Penn Interview for Decisional Abilities (IDA) In brief, in the absence of full standardization, comparison of psychometric properties across contexts becomes questionable. American Bar Association Commission on Law and Aging & American Psychological Association. Notably, although the standard consent model emphasizes an individual making a choice in isolation and/or in partnership with the clinician, in most aspects of everyday life, people commonly consult with trusted others for help with making choices. 1979. Given the time constraints placed on many clinicians, routine use of such instruments with every patient may not be a viable option. The MacCAT-T: A clinical tool to assess patients capacities to make treatment decisions. Background: Assessment of decisional capacity requires thorough clinical review of a patient's current psychiatric symptoms and cognitive processes. Reasoning in the capacity to make medical decisions: The consideration of values. Prevalence and predictors of mental incapacity in psychiatric in-patients. Bambara J. K., Griffith H., Martin R. C., Faught E., Wadley V. G., & Marson D. C. (2007). Decisional capacity impairments in psychotic patients are temporal, identifiable, and responsive to interventions directed towards simplifying information, encouraging training and shared decision making. As noted earlier, there are also a number of published instruments with preset content, i.e., employing a hypothetical vignette approach to decisional capacity assessment. Flexible item content potentially affects basic psychometric properties such as inter-rater and testretest reliability, as well as predictive or concurrent validity. For example, a comprehensive review found positive effects of multimedia consent aids on understanding among 23 of the 37 reviewed studies (Jeste, Dunn, Folsom, & Zisook, 2008). Assessing capacity to consent to treatment and research: a review of instruments. (2015). Thus, even when there is no reason to anticipate need for a formal court proceeding, the clinician is expected to consider a patient's decisional capacity. Moreover, the MaCAT-T is one of the few measures to have a detailed manual available to help guide administration, scoring, and interpretation of the instrument. For health and mental healthcare professionals, assessing an individual's capacity to consent to treatment is a necessary, if generally implicit, part of every encounter. Empirical advances in the assessment of the capacity to consent to medical treatment: clinical implications and research needs. Inclusion in an NLM database does not imply endorsement of, or agreement with, Voluntary informed consent is, with rare exceptions, a necessary, albeit not sufficient, defining precondition of ethical clinical treatment, and it is essential for enrollment in clinical research trials. Consistency of physician judgments of capacity to consent in mild Alzheimer's disease. The event was supported by the WHO Kenya Country Office and the Learning and Capacity Development Unit from WHO headquarters.

PDF Capacity 101 - Veterans Affairs (2008). In addition to the above recommendations, the particular context or needs of a specific patient or application may make one of the other available instruments a more viable or useful option in certain settings. Gurrera R. J., Karel M. J., Azar A. R., & Moye J. Palmer B. W., Dunn L. B., Depp C. A., Eyler L. T., & Jeste D. V. (2007). Accessed September 28, 2007.2. However, in a clinical context, their predictive validity and generalizability is less clear. Specifically, there is a generally recognized ethical duty to respect individuals as autonomous agents with the right to decide what happens (and does not happen) to their own bodies (Beauchamp & Childress, 2001), but there is also a duty to protect those with diminished capacity for autonomous decision making (National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research, 1979). Meisel A, Roth LH, Lidz CW. Kim S. Y., Karlawish J. H., Kim H. M., Wall I. F., Bozoki A. C., & Appelbaum P. S. (2011). Sturman ED. In higher risk populations or contexts, explicit formal/structured assessment of healthcare decisional capacity should be considered. Grisso T, Appelbaum PS, Mulvey EP, Fletcher K. The MacArthur Treatment Competence Study. Am J Psychiatry. Understanding likely requires both receipt of information (presumably dependent on both attention and receptive language skills), as well as the ability to temporarily store the information in active consciousness (working memory) in order to process/think about that information. Test administration is an invaluable component of assessment, but the skilled psychologist/neuropsychologist has a critical role in evaluating the test results in the larger clinical context. Such disengagement may involve the mental flexibility/shifting aspects of executive functions (Miyake et al., 2000; Savla et al., 2012), and then communication of the choice made requires some form of expressive language function. The site is secure. Dunn L. B., Nowrangi M. A., Be M., Palmer B. W., Jeste D. V., & Saks E. R. (2006). Burton C. Z., Twamley E. W., Lee L. C., Palmer B. W., Jeste D. V., Dunn L. B., et al. Grisso T, Appelbaum PS, Hill-Fotouhi C. The MacCAT-T: a clinical tool to assess patients' capacities to make treatment decisions. Waiting for transient interfering factors (such as anxiety or fatigue) and/or provision of further education can sometimes help resolve comprehension issues. Decisional Capacity for Informed Consent in - JAMA Network (1979). Effectiveness of multimedia aids to enhance comprehension during research consent: A systematic review. One primary methodological distinction among capacity assessment instruments is whether patients' decisional capacity is evaluated in reference to an actual treatment option or in reference to hypothetical vignettes. A prototypic example is an acutely suicidal person whose danger to self does not reflect his/her long-standing values or preferences, but rather the distortions frequently seen in an acute severe depressive, psychotic, and/or manic episode. Stroup S., Appelbaum P., Swartz M., Patel M., Davis S., Jeste D., et al. In that regard, members of our research group developed a brief (less than 5 minute) instrument to assess capacity to consent to research, the UCSD Brief Assessment of Consent Capacity (UBACC; Jeste et al., 2007), which has been subsequently modified and used in two studies of capacity to consent to treatment (Burton et al., 2012; Doyle et al., 2016). As such, the overall assessment of healthcare decision-making capacity should involve additional information, such as the specific nature of the proposed healthcare procedure or intervention, and the risks versus benefits of false-negative versus false-positive errors in capacity determinations within that context. The CCTI vignettes are presented in oral and written format, and the person is asked to imagine he/she has the condition specified in the scenario. Both are administered at 0, 8 . Roth LH, Meisel A, Lidz CW. Interested readers are referred to prior comprehensive reviews of these instruments for further details, which may help in selecting the instrument most appropriate to their specific need (Dunn, Nowrangi, Palmer, et al., 2006; Lamont et al., 2013; Palmer, Savla, et al., 2012; Sturman, 2005). An individual with dementia may have the capacity to make certain decisions which are not very complex or abstract, but not have the capacity to make more difficult decisions; that is to say, decisional capacity is fluid, and dependent on the nature of the decision which needs to be made. For example, none of the existing treatments for prostate cancer is risk or side-effect free, but the risk:benefit considerations vary among options, and the values individuals place on these risks and benefits may differ widely (O'Callaghan et al., 2014). Examples of Decisional capacity in a sentence. Notably, evidence for differential associations between specific cognitive domains and specific dimensions of decision-making capacity also tends to be marred by psychometric limitations in the available instruments. Evaluating Medical Decision-Making Capacity in Practice | AAFP In preparing this review, we conducted an updated search of the empirical literature but identified no additional comprehensive instruments of healthcare decision-making capacity that have been published in the interim period (In both reviews we excluded instruments that did not measure all four components detailed earlier). Preservation of the capacity to appoint a proxy decision maker: Implications for dementia research, Assessment of psychiatric patients competency to give informed consent: Legal safeguard of civil right to autonomous decision-making. Making Healthcare Decisions: A Report on the Ethical and Legal Implications of Informed Consent in the Patient-Practitioner Relationship. Once the decision to use a capacity instrument has been reached, one is still faced with the dilemma of choosing among the various available instruments. The key word in the preceding sentence is theorizing as, for reasons elaborated below, the empirical literature does not provide a basis for drawing firm conclusions about the role of specific cognitive domains on specific aspects of healthcare decision making. Neuropsychological correlates of competency loss in dementia using a simple legal standard [abstract]. In a low-risk or simple context, it may be acceptable to have this assessment as part of the informal/unstructured interview, but that discussion and assessment should still be guided by consideration of these four components. Mini-mental state: A practical method for grading the cognitive state of patients for the clinician. Jeste D. V., Dunn L. B., Folsom D. P., & Zisook D. (2008).

Ascertaining capacity to consent: a survey of approaches used by psychiatrists. Nonetheless, we believe these rational theorizations may have clinical utility in reasoning about the role of specific cognitive domains in healthcare decision-making capacity, thereby guiding assessment and intervention efforts, so we will briefly reiterate those theories here.
