Summary
This study developed the Suicide Knowledge Test (SKT) to measure suicide prevention knowledge. Results show the SKT is reliable and helps reduce stigma associated with suicidal behavior.
Area of Science:
- Psychology
- Public Health
- Psychometrics
Background:
- Accurate suicide knowledge is crucial for effective prevention strategies.
- Existing tools for assessing suicide knowledge may lack comprehensive psychometric validation.
- Understanding the relationship between suicide knowledge and stigma is essential for intervention development.
Purpose of the Study:
- To develop and psychometrically evaluate the Suicide Knowledge Test (SKT).
- To examine the internal structure and reliability of the SKT.
- To assess the construct validity of the SKT by examining its relationship with stigma.
Main Methods:
- A cross-sectional study was conducted with 303 Peruvian adults.
- Network analysis was used to examine the internal structure of the SKT.
- The SKT's relationship with the Stigma Scale for Receiving Psychological Help for Suicidal Behavior was assessed.
Main Results:
- The SKT demonstrated excellent reliability and a stable unidimensional structure.
- Knowledge of suicide risk minimization strategies and protective factors formed the most central network nodes.
- Suicide knowledge was negatively associated with stigma, supporting construct validity.
- The SKT's network structure was consistent across different professional groups.
Conclusions:
- The Suicide Knowledge Test (SKT) is a reliable instrument for assessing perceived knowledge about suicide.
- The SKT provides initial evidence of validity, particularly in its negative association with stigma.
- Findings support the utility of the SKT in research and practice for suicide prevention efforts.

01:22Self-Report Tests of Personality
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.
01:29Measures of Intelligence
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; it...

01:23Binet's Contribution to Measures of Intelligence
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 designs from...
