Summary
Residency interviewer scores vary significantly based on assessor profession. Diverse interviewer panels are recommended for reliable candidate selection in medical training programs.
Area of Science:
- Medical Education
- Psychology
- Organizational Behavior
Background:
- Residency interviewer scores exhibit significant variability.
- Factors influencing this variability, particularly assessor characteristics, remain unclear.
- Understanding how professional backgrounds impact scoring is crucial for fair evaluations.
Purpose of the Study:
- To investigate the influence of different professional backgrounds on residency interviewer scores.
- To identify potential biases stemming from diverse assessor professions.
Main Methods:
- Fifty-five general surgery applicants were assessed on teamwork.
- Applicants were scored by surgeons, human-resource managers, pilots, and athletes.
- Pearson's correlation, repeated-measures ANOVA, and structured interviews were employed.
Main Results:
- Significant differences in interview scores were observed across professions (F(3, 159) = 11.12, p < 0.001).
- Qualitative analysis indicated that assessors rely on global impressions and personal values when distinguishing between candidates.
- Subjectivity in scoring is influenced by the challenge of differentiating similar candidate performances.
Conclusions:
- Assessor variability in interviews is a common issue, partly due to subjective evaluations.
- Personal values significantly influence interviewer judgments.
- Implementing diverse interviewer panels is essential for enhancing the reliability of the selection process in residency programs.

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

The halo effect is a cognitive bias in which an individual's overall impression influences judgments about their specific traits. This psychological phenomenon leads people to associate positive characteristics with those they perceive as generally good and negative characteristics with those they view as bad. This effect is particularly influential in social perception, professional evaluations, and decision-making processes.The Psychological Basis of the Halo EffectThe halo effect is rooted...

01:25Strategies for Assessing and Addressing Confounding
163
Confounding is a critical issue in epidemiological studies, often leading to misleading conclusions about associations between exposures and outcomes. It occurs when the relationship between the exposure and the outcome is mixed with the effects of other factors that influence the outcome. Given that, addressing confounding is of high importance for drawing accurate inferences in research.
Confounding can be addressed at both the design phase of a study and through analytical methods after data...

01:29Bias in Epidemiological Studies
713
Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

01:22Bias
5.6K
Bias refers to any tendency that prevents a question from being considered unprejudiced. In research, bias occurs when one outcome or answer is selected or encouraged over others in sampling or testing. Bias can occur during any research phase, including study design, data collection, analysis, and publication.
In statistics, a sampling bias is created when a sample is collected from a population, and some members of the population are not as likely to be chosen as others (remember, each member...

02:01Group Design
9.7K
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...
