Summary
The Korean version of the Questions About Behavior Function (QABF-K) was developed and validated. This tool effectively identifies behavior functions in Korean-speaking populations, showing good reliability and an identical factor structure to the original.
Area of Science:
- Behavioral Psychology
- Psychometrics
- Clinical Assessment
Background:
- Understanding behavior function is essential for effective treatment of challenging behaviors.
- The Questions About Behavior Function (QABF) is a validated instrument for assessing behavior functions.
Purpose of the Study:
- To describe the development and psychometric properties of the Korean version of the QABF (QABF-K).
- To evaluate the reliability and factor structure of the QABF-K for use with Korean-speaking informants.
Main Methods:
- Development of the Korean translation of the QABF.
- Factor structure analysis of 153 QABF-K assessments.
- Assessment of internal consistency (Cronbach's alpha) and test-retest reliability.
Main Results:
- The QABF-K demonstrated a five-factor solution, consistent with the original English version.
- Good internal consistency was observed (Cronbach's alpha: 0.80–0.87).
- Strong test-retest reliability was found (correlation coefficients: 0.73–0.91).
Conclusions:
- The QABF-K is a psychometrically sound instrument for assessing behavior functions.
- It is a promising tool for clinicians and researchers working with Korean-speaking individuals.
- The validated QABF-K supports the development of functionally-based interventions in a new linguistic context.

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.
00:54What is Behavior?
Behaviors are actions that an organism engages in—they can be related to finding food, reproducing, defending against threats, and many other possible actions. Behaviors include activities related to the environment around the animal—such as migration—as well as social interactions within a species or population. Many behaviors involve motor output—that is, muscle movements—while others involve less visible actions, such as learning.
01:27Introduction to Developmental Psychology
Developmental psychology explores the changes and continuities in human abilities throughout life, encompassing physical, cognitive, linguistic, and social dimensions. Human development is not restricted to growth, but includes aspects of decline, particularly in physical abilities as individuals age. Developmental psychologists seek to understand how people change as they age and how their mental and social skills evolve.Developmental MilestonesA key concept in developmental psychology is...
02:16Surveys
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.
