Reliability and Validity01:29

Reliability and Validity

14.3K
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.

Uncertainty in Measurement: Accuracy and Precision

113.0K
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.

Self-Report Tests of Personality01:22

Self-Report Tests of Personality

1.1K
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.

Random Error01:04

Random Error

10.0K
Random or indeterminate errors originate from various uncontrollable variables, such as variations in environmental conditions, instrument imperfections, or the inherent variability of the phenomena being measured. Usually, these errors cannot be predicted, estimated, or characterized because their direction and magnitude often vary in magnitude and direction even during consecutive measurements. As a result, they are difficult to eliminate. However, the aggregate effect of these errors can be...

Random and Systematic Errors

15.7K
Scientists always try their best to record measurements with the utmost accuracy and precision. However, sometimes errors do occur. These errors can be random or systematic. Random errors are observed due to the inconsistency or fluctuation in the measurement process, or variations in the quantity itself that is being measured. Such errors fluctuate from being greater than or less than the true value in repeated measurements. Consider a scientist measuring the length of an earthworm using a...

Summary

Researchers developed the Scale of Unpredictability Beliefs (SUB) to measure perceptions of unpredictability. The SUB is a reliable tool for assessing beliefs about unpredictability in oneself, others, and the world.

Area of Science:

  • Psychology
  • Social Psychology

Background:

  • Environmental unpredictability is linked to negative outcomes.
  • Measuring unpredictability beliefs is challenging due to a lack of validated instruments.

Purpose of the Study:

  • To develop and validate the Scale of Unpredictability Beliefs (SUB).
  • To assess perceptions of unpredictability across self, others, and the world.

Main Methods:

  • Exploratory and confirmatory factor analyses were used across three studies with college students and adults.
  • Participants completed the SUB along with measures of childhood unpredictability, causal uncertainty, self-efficacy, personality, and control beliefs.

Main Results:

  • The SUB demonstrated a reliable three-factor structure (Self, People, World) with 16 items.
  • SUB scores correlated significantly with childhood family unpredictability, parental alcohol abuse, causal uncertainty, self-efficacy, personality traits, and control beliefs.
  • The SUB predicted family unpredictability and control beliefs beyond existing measures.

Conclusions:

  • The Scale of Unpredictability Beliefs is a psychometrically sound, multi-dimensional self-report measure.
  • The SUB provides a valuable tool for research on the impact of unpredictability beliefs.
  • Further research is needed to explore the full implications of the SUB.
