Abstract

Preliminary findings from an investigation of informed consent processes in four psychiatric research projects (two being carried out at a university medical center and two at a public psychiatric hospital) are reported. Study methods include the systematic observation of investigator/subject information disclosure sessions using audio and videotape, as well as the use of standardized interaction rating forms and subject understanding interviews. In an attempt to determine if subjects' understanding of research can be improved through increased subject education, several modes of information disclosure are compared. Partial results from the public psychiatric hospital portion of the investigation suggest low subject understanding in many areas with subjects often demonstrating difficulty differentiating between treatment and biomedical research. Subjects' problematic understanding of research purposes and methodology was compounded by investigator disclosures which often emphasized the therapeutic, personalistic and nonresearch-oriented aspects of the project. Nevertheless, even when information disclosures were significantly improved, subject understanding in many cases continued to be low— suggesting that additional factors aside from the quality of investigator disclosure are involved in psychiatric subjects' comprehension and understanding of research. The implication of these findings for informed consent, regulation of biomedical research and the protection of human subjects are discussed.

      Decision-making capacity refers to subjects' ability to understand relevant information, to appreciate the significance of that information, and to reason through to a conclusion that makes sense for them.18 These concerns parallel the concerns in research involving patients with dementia,19 psychiatric illness,20,21 and patients in the intensive care setting,22 among others. Concerns about capacity are warranted, given the prevalence of cognitive impairment at the end of life.23–26
