Feedback Loops01:01

Feedback Loops

In most cases, excessive hormone production is prevented by negative feedback—a loop that starts with a stimulus inducing the release of a particular substance, like a hormone, to maintain a certain level before triggering a signal that results in a decrease in further release of the hormone.

Sources of Self-Esteem II: Performance Feedback

Self-esteem is intricately tied to our perception of competence and our ability to exert control over our lives. One of the primary sources of this perception is performance feedback — the ongoing evaluation of our actions in terms of success and failure. According to Franks and Marolla (1976), people derive self-worth from experiencing themselves as causal agents, capable of achieving goals and overcoming obstacles. This process nurtures a critical component of self-esteem: self-efficacy,...
Feedback Inhibition00:46

Feedback Inhibition

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

Area of Science:

  • Medical Education
  • Healthcare Professional Development

Background:

  • Supervisors are crucial for postgraduate medical trainee development, overseeing clinical practice and supporting learning.
  • A distinction exists in the UK between clinical oversight and educational support roles for supervisors.

Purpose of the Study:

  • To develop and validate a web-based multisource feedback (MSF) tool for educational supervisors.
  • To provide a reliable instrument for assessing supervisor effectiveness in the London Deanery.

Main Methods:

  • Literature review to create a question framework, followed by focus groups and interpretative thematic analysis.
  • Online piloting of the instrument, with performance analysis using factor analysis and generalisability theory.
  • Implementation and validation of the tool over its first year.

Main Results:

  • The developed instrument identified two key factors, with three questions removed due to poor performance.
  • Educational supervisors generally rated themselves lower than their trainees did.
  • The MSF tool was launched in July 2010, requiring five respondents for a report, with ongoing validity evidence collection.

Conclusions:

  • The London Deanery MSF instrument for educational supervisors is a valid tool.
  • The tool provides useful evidence of supervisor effectiveness, arising from a robust development process.
