Reliability and Validity01:29

Reliability and Validity

12.7K
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.

Stereotype Threat and Self-fulfilling Prophecies

37.6K
When we hold a stereotype about a person, we have expectations that he or she will fulfill that stereotype. A self-fulfilling prophecy is an expectation held by a person that alters his or her behavior in a way that tends to make it true. When we hold stereotypes about a person, we tend to treat the person according to our expectations. This treatment can influence the person to act according to our stereotypic expectations, thus confirming our stereotypic beliefs. Research by Rosenthal and...

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.

Anxiety: Overview

283
Anxiety is a common mental disorder featuring excessive worry, fear, and apprehension, significantly affecting daily life. People with anxiety disorders experience persistent and intense anxiety, interrupting their everyday functioning.
Individuals with anxiety often experience a range of physical and emotional symptoms, including sweating, trembling, tachycardia, and disturbances in sleep patterns. These symptoms vary in intensity and frequency but are generally disruptive and distressing.

Generalized Anxiety Disorder01:30

Generalized Anxiety Disorder

139
Generalized Anxiety Disorder (GAD) is a chronic condition characterized by excessive and uncontrollable worry that persists for at least six months, significantly interfering with daily functioning. Unlike situational anxiety, which arises in response to specific stressors, GAD often occurs without a clear cause. Individuals may experience disproportionate worry about work, health, or relationships. For instance, a person might continuously fear poor health despite normal medical evaluations or...

Summary

Researchers developed the Brief Math Anxiety Scale (BMAS), a shorter version of the Shortened Math Anxiety Rating Scale (sMARS). This validated nine-item scale accurately measures math anxiety in university students, even under time constraints.

Area of Science:

  • Psychological Measurement
  • Educational Psychology
  • Quantitative Psychology

Background:

  • The Shortened Math Anxiety Rating Scale (sMARS) is a widely used measure.
  • Existing scales may be lengthy for certain research or clinical situations.
  • Developing brief, psychometrically sound instruments is crucial for efficient assessment.

Purpose of the Study:

  • To develop a brief version of the sMARS, named the Brief Math Anxiety Scale (BMAS).
  • To maintain the original three-factor structure of the sMARS.
  • To validate the psychometric properties of the new brief scale.

Main Methods:

  • Item response theory was applied to refine the sMARS.
  • The sMARS was administered to a sample of 1,349 undergraduates.
  • Correlations with measures of math ability, trait anxiety, test anxiety, and attitudes toward mathematics were examined.

Main Results:

  • The scale was successfully reduced to nine items, with three items per subscale.
  • The Brief Math Anxiety Scale (BMAS) demonstrated strong internal consistency.
  • Adequate test-retest reliability (7-week) and good convergent/discriminant validity were established.

Conclusions:

  • The BMAS is a valid and reliable instrument for assessing math anxiety in university students.
  • The BMAS is particularly useful in time-constrained settings.
  • The scale supports accurate interpretation of scores for research and practice.
