Summary
Most scales measuring discrimination against sexual minorities have poor psychometric properties. This review highlights significant limitations in validity and reliability, impacting research on lesbian, gay, and bisexual (LGB) well-being.
Area of Science:
- Psychology
- Sociology
- Public Health
Background:
- Discrimination against sexual minorities (lesbian, gay, bisexual - LGB) is prevalent and harmful.
- Existing research lacks a comprehensive review of measurement tools for LGB discrimination.
Purpose of the Study:
- To evaluate the psychometric properties of instruments used to measure discrimination against sexual minorities.
- To identify limitations in current measurement scales and suggest improvements.
Main Methods:
- Systematic review of 162 articles measuring LGB discrimination.
- Evaluation of psychometric properties including content validity, reliability, dimensionality, and criterion- and construct-related validity.
Main Results:
- Most reviewed scales exhibit suboptimal psychometric properties.
- Common limitations include inadequate content validity, absence of reliability metrics, untested dimensionality, and omitted validity testing.
- Scales are often adapted from other discrimination measures without sufficient validation for LGB populations.
Conclusions:
- Current measures of LGB discrimination suffer from significant psychometric weaknesses.
- The lack of "gold standard" instruments hinders coherent research synthesis.
- Improvements in scale development and validation are crucial for accurate assessment of discrimination's impact.

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

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.

The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

01:31Confirmation Biases

The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?

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;...
