Summary
This review found significant gaps in tools measuring ageism, highlighting a need for better instruments to assess attitudes towards older adults and promote healthy aging.
Area of Science:
- Gerontology
- Psychometrics
- Public Health
Background:
- Global population aging necessitates focus on healthy aging and well-being.
- Ageism and its assessment remain under-explored areas in gerontology.
- This review critically examines instruments measuring ageism against older individuals.
Purpose of the Study:
- To evaluate the psychometric properties of existing ageism assessment tools.
- To identify gaps in the measurement of ageism.
- To inform the development of more robust assessment instruments.
Main Methods:
- Systematic literature search across seven major databases.
- Utilized the COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN) checklist.
- Assessed methodological quality, internal consistency, and cross-cultural validity of included studies.
Main Results:
- 20 studies were included from over 338,000 initial outputs.
- Eight studies focused on self-directed ageism, 12 on attitudes towards older individuals.
- No studies met high methodological quality for content validity; cross-cultural validity was assessed in only three studies.
Conclusions:
- Significant deficiencies exist in the psychometric properties of current ageism assessment tools.
- Further refinement and validation are crucial for reliable and comprehensive ageism measurement.
- Findings support policymakers and researchers in developing better tools for gerontological research.

01:29Reliability and Validity
12.6K
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.

02:55Stereotypes, Prejudice, and Discrimination
89.7K
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...

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...

01:29Measures of Intelligence
5.5K
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;...

01:23Binet's Contribution to Measures of Intelligence
1.2K
Alfred Binet, along with his student Théophile Simon, was tasked by the French Ministry of Education in 1904 to create a method for identifying students who struggled to learn through conventional classroom instruction. This initiative aimed to address overcrowding by placing such students in specialized schools. Binet and Simon developed an intelligence test comprising 30 tasks, ranging from simple commands, like touching one's nose or ear, to more complex tasks, such as drawing...

01:22Self-Report Tests of Personality
275
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.
