Unit 10 - The IB Curriculum - A Conceptual Model

Accuracy (Validity): Hitting the bull&#39;s eye in the target. In diagnosis, this means getting the diagnosis right.

&nbsp;

Consistency (Reliability): Hitting the same spot, even if it&#39;s not the bull&#39;s eye. In diagnosis, this means making the same diagnosis across different times or different doctors.

Hit the Bull&#39;s Eye Every Time: The dream! But it&#39;s hard to achieve

.

Reliable but Invalid Diagnosis: Think of hitting the same wrong spot. Everyone agrees but it&#39;s still wrong. That&#39;s dangerous!

&nbsp;

Unreliable but Valid Diagnosis: A paradox! Like hitting the right spot once but never again.

&nbsp;

Valid is Reliable, but Reliable isn&#39;t always Valid: Hitting the bull&#39;s eye means you&#39;re consistent at it, but hitting the same wrong spot is not valid.

Ethical Issues: Wrong diagnosis can lead to stigmatization, like labeling someone incorrectly.

&nbsp;

Treatment Issues: Like using the wrong ammunition for the target, wrong treatment won&#39;t solve the problem.

More Validity, Less Reliability: Like trying to hit a moving target by interpreting a patient&rsquo;s behavior, it&#39;s more accurate but harder to hit consistently.

&nbsp;

More Reliability, Less Validity: Like hitting a bigger but wrong target, standardizing criteria might be consistent but superficial.

Standardized Tests in Schools: They are like hitting the same spot every time (reliable) but may not capture a student&#39;s full abilities (less valid).

&nbsp;

Doctors Diagnosing a Common Cold vs. a Complex Disorder: Diagnosing a cold is like hitting a big, easy target (reliable) but diagnosing a complex disorder might require more interpretation and could be less consistent (more valid).

Diagnosing a medical condition is like target practice. Accuracy (validity) is about hitting the right spot, while consistency (reliability) is about hitting the same spot every time. But sometimes, striving for one can mean sacrificing the other. Like a skilled archer, clinicians must find the right balance to hit the bull&#39;s eye!

&nbsp;

Now, imagine yourself as an archer and your school exams as the targets. Just as doctors have to make accurate and consistent diagnoses, you need to study and prepare in a way that helps you hit the bull&#39;s eye every time!

Happy studying! 📚
