Blind Procedures

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 child was...

Blinding

Blinding

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.

The Scientific Method

The Scientific Method

Research is what makes the difference between facts and opinions. Facts are observable realities, and opinions are personal judgments, conclusions, or attitudes that may or may not be accurate. In the scientific community, facts can be established only using evidence collected through empirical research.

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

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, controlled...

Randomized Experiments

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.

Area of Science:

Medical Education
Professionalism in Medicine

Background:

Competency frameworks like CanMEDS define professional behavior in medicine.
Existing educational programs often lack practical application of these frameworks.
Translating theoretical CanMEDS concepts into practical skills is a recognized challenge.

Purpose of the Study:

To evaluate the effectiveness of a novel near-peer shadowing program for teaching the CanMEDS framework to first-year medical students.
To assess the impact of the program on students' attitudes, knowledge, and understanding of professional behavior.

Main Methods:

A randomized trial compared a program group (83 first-year medical students shadowing residents) with a control group.
A concurrent-triangulation mixed methods design utilized questionnaires and interviews.
Data collection focused on participants' attitudes and knowledge regarding the CanMEDS framework.

Main Results:

Students in the program demonstrated significantly increased understanding and acceptance of the CanMEDS framework compared to controls.
Both students and residents reported enhanced knowledge of CanMEDS.
Participants found the program effective for learning CanMEDS and developing professionalism, particularly when linked to clinical experiences.

Conclusions:

A simple, low-cost near-peer shadowing program can be an effective tool for teaching professional behavior.
This program offers a practical approach to integrating competency frameworks into medical education.
The findings suggest a valuable method for enhancing CanMEDS instruction and fostering professionalism.
