Blinding01:11

Blinding

2.5K
Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

145
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Randomized Experiments

The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

Blind Procedures

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

Ethics in Research

23.0K
Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.

Group Design02:01

Group Design

9.0K
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between...

Summary
This summary is machine-generated.

This study found that exposure to post-doctoral researchers or supervisors did not significantly impact doctoral students' research integrity choices when facing dilemmas. Most students, even when unexposed, sometimes chose detrimental research practices.

Area of Science:

  • Scientific integrity
  • Doctoral education
  • Research ethics

Background:

  • Research integrity is crucial for scientific advancement.
  • Doctoral students may face ethical dilemmas during their training.
  • Inappropriate research environments can potentially influence ethical decision-making.

Purpose of the Study:

  • To describe doctoral students' research practices when confronted with ethical dilemmas.
  • To assess the impact of exposure to detrimental research practices (DRP) by peers and supervisors on student choices.
  • To evaluate the influence of inappropriate research environments on research integrity.

Main Methods:

  • Two parallel-group randomized controlled trials were conducted.
  • 10 vignettes depicting ethical dilemmas were created, presenting good practice versus DRP.
  • 630 PhD students were randomized to vignettes with or without exposure to a post-doctoral researcher or supervisor involved in DRP.

Main Results:

  • 37% of unexposed participants opted for DRP, with significant variation across vignettes.
  • Exposure to a post-doctoral researcher who committed DRP showed no significant impact (mean difference: 0.17, p=0.65).
  • Exposure to a supervisor who did not oppose DRP also showed no significant impact (mean difference: 0.79, p=0.16).

Conclusions:

  • The study did not find evidence that post-doctoral researchers or supervisors significantly influence doctoral students' research integrity practices.
  • Doctoral students' choices regarding research integrity dilemmas appear complex and not solely determined by immediate environmental influences.
  • Further research may be needed to explore other factors affecting research integrity in doctoral candidates.
