Individuals with cognitive impairment can participate in dementia research decisions. They prefer a "best interests" ethical standard for future proxy decisions, sometimes combined with other approaches.
Area of Science:
- Neuroscience
- Bioethics
- Clinical Research
Background:
- Dementia research requires ethical decision-making processes for participant involvement.
- Understanding the perspectives of individuals with cognitive impairment and their surrogates is crucial for ethical research conduct.
Purpose of the Study:
- To examine how individuals with cognitive impairment make decisions about participating in dementia research.
- To explore their preferences for ethical standards in future proxy research decisions.
Main Methods:
- Cross-sectional qualitative study using semistructured interviews.
- Involved 39 individuals with cognitive impairment and 46 study partners/surrogate decision-makers.
- Content analysis of transcribed interviews.
Main Results:
- Discrepancies were noted between subjects and surrogates regarding decision-making processes for study participation.
- Subjects and surrogates often disagreed on who made the final decision, though subjects were most frequently cited.
- For future proxy decisions, the 'best interests' standard was preferred, with some favoring a combination of standards.
Conclusions:
- Individuals with mild to moderate cognitive impairment can actively engage in research decision-making.
- Their expressed preferences for future proxy decisions should be considered.
- Supports obtaining both proxy consent and subject assent when capacity is limited.
