“…Of the five negative studies, two were inconclusive regarding the effect of simplified, more readable consent forms on patient understanding Taub et al 1987). Two other reports on corrected feedback (Taub and Baker 1983) and the addition of an oral discussion to written information (Tindall et al 1994) produced mixed results. The latter study demonstrated improvement from pre-to postconsent, but the oral discussion did not add significantly to this improvement.…”

“…Eight reported a positive association (Bjorn et al 1999;Young et al 1990;Taub et al 1986;Taub et al 1987;Sorrell 1991;Neptune et al 1996;Aaronson et al 1996;Agre et al 1994). Two studies that evaluated patients' vocabulary levels (as measured by the vocabulary subtest of the Wechsler Adult Intelligence Scale [WAIS]) found that performance on immediate as well as delayed tests of understanding varied directly with vocabulary level (Taub and Baker 1983;Taub et al 1981).…”

“…We identified a number of studies that attempted to measure the effectiveness of various interventions over time, thereby providing some information, not merely about immediate recall but also about the durability of information provided (Simes et al 1986;Taub et al 1981;Taub and Baker 1983;Tindall et al 1994;Tymchuk et al 1988). Because the timing of measurement of understanding varied greatly among studies, caution is indicated when comparing results.…”

“…The differences in understanding due to education were often large, especially compared with the improvements produced by the various interventions. For example, Taub and Baker 13 documented that a feedback intervention increased average understanding scores by 29%, but there was a 95% difference between the least educated quartile of research participants and the most educated quartile. However, they also acknowledged that participants' recall of the information presented to them during the interview may not always reflect their actual understanding of such information.…”

The informed consent process provides protection by ensuring that potential research subjects understand the goals of the research project they are being asked to voluntarily partake in as well as the risks associated with the study. We examined subjects' comprehension and ability to identify issues explicitly raised during the consent process that was conducted as part of their participation in a genetic family study (GFS). We employed cross-sectional design by providing a short, selfadministrative questionnaire to 246 participants recruited from families enrolled in the Extended Family Investigation of Nephropathy and Diabetes (EFIND) study conducted at the University of Texas Health Science Center. Participants responded to the questionnaire directly after their enrollment in the EFIND study. The questionnaire consisted of multiple-choice questions and focused on the understanding of the purposes, procedures, and risks associated with their participation in the EFIND study. These questions were formulated to reflect basic information presented to subjects through the consent process. Responses to questions were expressed as percentages, placing equal weight on each response. Participants were Mexican-American, 62.3% female and averaged 35.2 ±12.7 years old (range: 18-76). Our findings showed that the average comprehension score was 58. About 30% of the participants did not know the name of the study, and 70% did not identify all elements related to the study procedures. The most striking finding was the lack of understanding concerning the social risks associated with participation in EFIND. While 35.1% of participants identified all potential physical risks, only 1.3% could identify all of the social risks. Our findings showed that participants comprehension score was significantly associated with their level of education and income. We conclude that using the informed consent process to communicate research social risks to subjects participating in GFS has some limitations. Future research directed at improving risk communications to subjects of low socioeconomic levels participating in genetic research is justified.

“…Taub and colleagues conducted a number of studies comparing elderly and non-elderly adults in their ability to recall information contained in informed consent forms (see, e.g., Taub, 1980). These studies typically demonstrated poorer retention among the elderly participants, as well as associations between retention and levels of education and verbal abilities (Taub, 1979;Taub & Baker, 1983;Taub, Baker, & Sturr, 1986;Taub, Kline, & Baker, 1981). Other researchers have found improvements in retention of informed consent material when this information is presented in a simplified manner (e.g.…”

Despite the importance and complexity of evaluating decision-making capacity at the end of life, little research has focused on terminally ill patients' decision-making ability. The purpose of this study was to explore the decision-making capacity of elderly, terminally ill patients and the psychological and physical factors that affect decision making. Decision-making capacity and cognitive abilities were assessed using four measures: the Hopkins Competency Assessment Kit, the Bechara Gambling Task, the Concept Assessment Kit, and the Mini Mental Status Exam. In addition, symptoms of depression, level of physical functioning, and extent of physical symptoms were evaluated in order to identify correlates of decision-making ability. Two samples were compared: elderly, terminally ill patients with cancer (n = 43) and elderly, physically healthy adults living in supportive community residence (n = 35). Results revealed significantly poorer decision-making abilities among the terminal ill sample compared with healthy comparisons, but no association between demographic variables (e.g., age, race, or education) or clinical variables (depression or physical symptoms) and decision making. Implications for evaluating decision-making capacity are addressed.
