Urologic Endoscopic Procedure: Cystoscopic Examination01:28

Urologic Endoscopic Procedure: Cystoscopic Examination

2.9K
Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...

Factorial Design02:01

Factorial Design

13.8K
Factorial Analysis is an experimental design that applies Analysis of Variance (ANOVA) statistical procedures to examine a change in a dependent variable due to more than one independent variable, also known as factors. Changes in worker productivity can be reasoned, for example, to be influenced by salary and other conditions, such as skill level. One way to test this hypothesis is by categorizing salary into three levels (low, moderate, and high) and skills sets into two levels (entry level...

Correlation and Causation01:27

Correlation and Causation

42.5K
Statistical tests can calculate whether there is a relationship, or correlation, between independent and dependent variables. An indirect relationship of the variables signifies a correlation, while a direct relationship shows causation. If it is determined that no connection exists between the variables, then the correlation is a coincidence.
Correlation versus Causation
If the dependent variable increases or decreases when the independent variable increases, there is a positive or negative...

Attitudes01:54

Attitudes

33.2K
Attitude is our evaluation of a person, an idea, or an object. We have attitudes for many things ranging from products that we might pick up in the supermarket to people around the world to political policies. Typically, attitudes are favorable or unfavorable: positive or negative (Eagly & Chaiken, 1993). And, they have three components: an affective component (feelings), a behavioral component (the effect of the attitude on behavior), and a cognitive component (belief and knowledge;...

Gene Evolution - Fast or Slow?02:05

Gene Evolution - Fast or Slow?

8.2K
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...

Gene Families01:57

Gene Families

9.9K
Gene families consist of groups of genes proposed to have originated from a common ancestor. Typically these arise through events in which a gene or genes are mistakenly duplicated during cell division. Unlike their parent genes (which are subject to selection pressure to maintain function), these gene copies do not need to preserve their sequences and may evolve at a relatively faster rate.
Occasionally these regions can be adapted to take on new roles within the organism, becoming novel genes...

Summary

The American Board of Physical Medicine and Rehabilitation (ABPMR) certification exams, Part I and Part II, assess different candidate knowledge dimensions. Part II offers unique insights into systems-based practice and communication skills beyond Part I.

Area of Science:

  • Medical Education
  • Psychometrics
  • Rehabilitation Medicine

Background:

  • Physical Medicine and Rehabilitation (PM&R) certification requires passing written (Part I) and oral (Part II) exams.
  • The extent to which these exams assess distinct knowledge domains remains unclear.

Purpose of the Study:

  • To assess the concordance between Part I and Part II examinations for ABPMR initial certification.
  • To determine if Part II provides additional assessment beyond Part I.

Main Methods:

  • Retrospective psychometric analysis of deidentified ABPMR board examination scores.
  • Utilized correlations, simple linear regressions, and principal components analysis.

Main Results:

  • A weak to moderate correlation (r=0.33, P<.001) was found between Part I and Part II performance.
  • Part II demonstrated an additional dimension of assessment, particularly in systems-based practice and interpersonal communication skills.

Conclusions:

  • Part I and Part II examinations contribute distinct, meaningful components to the overall evaluation of PM&R board certification candidates.
  • The two-part examination structure provides a more comprehensive assessment of candidate competency.
