Summary
A new scale effectively measures interprofessional collaboration among nurses and physicians. This tool shows promise for assessing teamwork across diverse healthcare professionals in acute care settings.
Area of Science:
- Healthcare Management
- Nursing Research
- Health Services Research
Background:
- Existing interprofessional collaboration scales are often limited to a single health profession, typically nurses.
- A validated measurement scale for interprofessional collaboration is needed for multiple provider groups, including physicians, in acute care.
Purpose of the Study:
- To develop and validate a new interprofessional collaboration measurement scale suitable for nurses, physicians, and other health professionals.
- To assess the validity and reliability of data from nurses evaluating physician collaboration.
Main Methods:
- Adapted a nurse-specific scale into a round-robin proxy report format for multiple health professions.
- Administered the adapted scale to registered nurses, physicians, and allied health professionals across 15 hospitals in Toronto, Canada.
- Utilized exploratory and confirmatory factor analysis to examine scale dimensionality, validity, and reliability.
Main Results:
- Exploratory and confirmatory factor analysis identified three factors: Communication, Accommodation, and Isolation.
- Nurses' ratings of physician collaboration demonstrated convergent, discriminant, and concurrent validity, with acceptable reliability.
- Initial results suggest potential validity and reliability for other rater/target combinations.
Conclusions:
- The developed scale is suitable for nurses assessing physicians in acute care settings.
- Further investigation into measurement equivalence is recommended before widespread use across multiple health professional groups.

01:29Reliability and Validity
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.
01:22Self-Report Tests of Personality
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.
01:29Measures of Intelligence
Psychologists measure intelligence by using standardized tests that produce a score known as the intelligence quotient or IQ. To understand IQ tests, it's important to recognize the key principles behind their construction: validity, reliability, and standardization.
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this; it...

00:55Ordinal Level of Measurement
The way a set of data is measured is called its level of measurement. Correct statistical procedures depend on a researcher being familiar with levels of measurement. For analysis, data are classified into four levels of measurement—nominal, ordinal, interval, and ratio.
Data measured using an ordinal scale are similar to nominal scale data, but there is one major difference. The ordinal scale data can be ordered. An example of ordinal scale data is a list of the top five national parks in the...

01:23Wechsler's Contribution to Measures of Intelligence
David Wechsler, a psychologist who worked with World War I veterans, developed a significant IQ test in 1939 called the Wechsler-Bellevue Intelligence Scale. This test was innovative because it combined several subtests that measured both verbal and nonverbal skills, reflecting Wechsler's belief that intelligence is a global capacity involving purposeful action, rational thinking, and effective interaction with the environment. This test later evolved into the Wechsler Adult Intelligence Scale...
00:54Ratio Level of Measurement
The way a set of data is measured is called its level of measurement. Correct statistical procedures depend on a researcher being familiar with levels of measurement. For analysis, data are classified into four levels of measurement—nominal, ordinal, interval, and ratio.
A set of data measured using the ratio scale takes care of the ratio problem and provides complete information. Ratio scale data are like interval scale data, except they have a zero point and ratios can be calculated. For...
