Self-Report Tests of Personality01:22

Self-Report Tests of Personality

344
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.

Ordinal Level of Measurement00:55

Ordinal Level of Measurement

23.6K
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...

Self-Discrepancy Theory02:45

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Uncertainty in Measurement: Reading Instruments

Counting is the type of measurement that is free from uncertainty, provided the number of objects being counted does not change during the process. Such measurements result in exact numbers. By counting the eggs in a carton, for instance, one can determine exactly how many eggs are there in the carton. Similarly, the numbers of defined quantities are also exact. For example, 1 foot is exactly 12 inches, 1 inch is exactly 2.54 centimeters, and 1 gram is exactly 0.001 kilograms. Quantities...

Deindividuation00:57

Deindividuation

26.4K
Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.

Uncertainty in Measurement: Accuracy and Precision

73.7K
Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy of their results. Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is very close to the true or the accepted value. Precise values agree with each other; accurate values agree with a true value.

Summary
This summary is machine-generated.

The short-form Confusion, Hubbub and Order Scale (CHAOS) needs revision. This study found measurement non-invariance and inconsistent predictive validity, questioning its current use in developmental research.

Area of Science:

  • Psychometrics
  • Developmental Psychology
  • Behavioral Science

Background:

  • The Confusion, Hubbub and Order Scale (CHAOS) short-form is a widely used survey for assessing home environments in child development and psychopathology research.
  • While the original 15-item scale was validated, the 6-item short-form, developed in the late 1990s, has not undergone validation.

Purpose of the Study:

  • To validate the 6-item short-form of the CHAOS scale.
  • To examine measurement invariance and predictive validity across diverse international twin study samples.
  • To assess the appropriateness of one-factor versus two-factor models for the CHAOS short-form.

Main Methods:

  • Utilized five international twin study samples (Australia, UK, USA).
  • Conducted confirmatory factor analysis comparing one-factor and two-factor models.
  • Performed tests for configural, metric, and scalar measurement invariance across groups.
  • Examined predictive validity using socioeconomic status and academic achievement.

Main Results:

  • A two-factor model demonstrated a better fit than the commonly used one-factor model for the CHAOS short-form.
  • Significant measurement non-invariance was detected at the metric level, indicating differential item functioning across samples.
  • Predictive validity analyses yielded inconsistent results when using socioeconomic status and academic achievement as criteria.

Conclusions:

  • The current 6-item CHAOS short-form exhibits measurement non-invariance and lacks consistent predictive validity, raising concerns about its reliability.
  • The findings suggest that the scale's structure and item performance vary significantly across different populations.
  • Revisions and further development of the CHAOS short-form are recommended for its accurate application in developmental research.
