Chapter 4: Problem 111

In the \(1960 \mathrm{~s}\) children entering the Willowbrook State School, an institution for the intellectually disabled on Staten Island in New York, were deliberately infected with hepatitis. The researchers argued that almost all children in the institution quickly became infected anyway. The studies showed for the first time that two strains of hepatitis existed. This finding contributed to the development of effective vaccines. Despite these valuable results, the Willowbrook studies are now considered an example of unethical research. Explain why, according to current ethical standards, useful results are not enough to allow a study.

Short Answer

Expert verified
The Willowbrook study was unethical because it lacked informed consent, exposed participants to harm, and violated their rights.

Step by step solution

01

Introduction to Ethical Concerns

The Willowbrook study involved deliberately infecting children with hepatitis, which raises significant ethical concerns. According to current ethical standards, research must prioritize the safety and well-being of participants above the potential benefits of the research findings.
02

Principle of Informed Consent

One critical ethical standard is the principle of informed consent. Participants, or their guardians in the case of minors, should be fully aware of and agree to the procedures and potential risks involved. In the Willowbrook case, it is likely that the children, who were intellectually disabled, and possibly their guardians, may not have fully understood or agreed to the risks.
03

Consideration of Minimal Harm

Another ethical standard is the principle of minimizing harm. Research should not expose participants to additional risks beyond those encountered in everyday life. The deliberate infection of children with hepatitis constituted a significant and unnecessary risk.
04

Respect for Individuals' Rights

Ethical research must respect the rights of individuals involved. This includes the right to withdraw from the study at any time without adverse consequences, which may have not been assured or respected in the Willowbrook study.
05

Balancing Risks and Benefits

Current ethical guidelines, such as those outlined in the Belmont Report, emphasize that the potential benefits of a study should outweigh the risks involved. Although the Willowbrook study produced valuable findings, the risks to participants were disproportionately high compared to the potential benefits.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Informed Consent
Informed consent is a foundational principle in ethical research. It ensures that participants are fully aware of the nature of the study, including its purpose, procedures, and potential risks.
For research involving minors, like in the Willowbrook study, consent must be obtained from their guardians.
  • Informed consent means providing potential participants with all the necessary information to make an educated decision about their involvement.
  • Researchers must ensure that the provided information is understandable, especially when involving vulnerable populations.
  • The absence of informed consent violates participants鈥� autonomy and ethical standards.
In the Willowbrook case, the complexity of the study and the vulnerability of the participants made it difficult to ascertain whether true informed consent was given.
Minimizing Harm
Minimizing harm is another critical aspect of conducting ethical research. This principle requires that researchers design studies in a manner that avoids unnecessary risks and harm to participants.
Here are some key points:
  • Research should not deliberately expose participants to risks greater than those they encounter in everyday life.
  • Participants鈥� safety and welfare must be prioritized over the objectives of the research.
  • Ethical research involves constant assessment of risks to promptly address any potential harm.
In the Willowbrook study, children were intentionally infected with hepatitis, causing harm that was not essential or justified by the research goals.
Respect for Participants' Rights
Respecting participants' rights is an essential component of ethical research practices. This means ensuring that participants are treated with dignity and are given control over their involvement in the study.
Some fundamental rights include:
  • The right to withdraw from the study at any time without facing negative consequences.
  • The right to confidentiality and protection of personal information.
  • The right to be informed of the study鈥檚 outcomes and any implications that might affect them directly.
The Willowbrook study may have neglected these rights, particularly if the children's or guardians' ability to withdraw was restricted.
Risk-Benefit Analysis
Risk-benefit analysis is essential in evaluating whether a study should proceed. It involves weighing the potential benefits against the risks to participants.
Key considerations include:
  • The benefits of the research should justify the risks to the participants.
  • Researchers must continuously assess and minimize any potential harms during the study.
  • Studies should aim to enhance knowledge or societal well-being significantly beyond the risks they present.
In the Willowbrook study, despite achieving valuable medical insights, the severe risks and ethical breaches outweighed the scientific benefits due to the method of infection used on vulnerable participants.

Ma, no hands! Does talking on a hands-free cell phone distract drivers? Researchers recruit 40 student subjects for an experiment to investigate this question. They have a driving simulator equipped with a handsfree phone for use in the study. Each subject will complete two sessions in the simulator: one while talking on the hands-free phone and the other while just driving. The order of the two sessions for each subject will be determined at random. The route, driving conditions, and traffic flow will be the same in both sessions. (a) What type of design did the researchers use in their study? (b) Explain why the researchers chose this design instead of a completely randomized design. (c) Why is it important to randomly assign the order of the treatments? (d) Explain how and why researchers controlled for other variables in this experiment.

A lumber company wants to estimate the proportion of trees in a large forest that are ready to be cut down. They use an aerial map to divide the forest into 200 equal-sized rectangles. Then they choose a random sample of 20 rectangles and examine every tree that's in one of those rectangles. (a) What is the name for this kind of sampling method? (b) Give a possible reason why the lumber company chose this method.

What proportion of students at your school use Twitter? To find out, you survey a simple random sample of students from the school roster. (a) Will your sample result be exactly the same as the true population proportion? Explain. (b) Which would be more likely to get your sample result closer to the true population value: an SRS of 50 students or an SRS of 100 students? Explain.

A biologist would like to determine which of two brands of weed killer, X or \(Y\), is less likely to harm the plants in a garden at the university. Before spraying near the plants, the biologist decides to conduct an experiment using 24 individual plants. Which of the following two plans for randomly assigning the treatments should the biologist use? Why? Plan A: Choose the 12 healthiest-looking plants. Then flip a coin. If it lands heads, apply Brand X weed killer to these plants and Brand Y weed killer to the remaining 12 plants. If it lands tails, do the opposite. Plan B: Choose 12 of the 24 plants at random. Apply Brand X weed killer to those 12 plants and Brand \(Y\) weed killer to the remaining 12 plants.

Identify the experimental units, the explanatory and response variables, and the treatments. \(\Lambda\) student project measured the increase in the heart rates of fellow students when they stepped up and down for 3 minutes to the beat of a metronome. The step was either 5.75 or 11.5 inches high and the metronome beat was \(14,21,\) or 28 steps per minute. Thirty students took part in the experiment. Five of them stepped at each combination of height and speed.
