Self-Report Tests of Personality01:22

Self-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.

Cattell's 16 Personality Factors

Raymond Cattell's trait theory offers a structured framework for understanding personality by distinguishing between two critical traits: surface and source traits. Surface traits are observable patterns of behavior, such as indecisiveness, anxiety, and irrational fears. These traits are less stable, varying across situations and over time. This means that they are less helpful in understanding the deeper aspects of an individual's personality.
In contrast, source traits are the fundamental,...

Area of Science:

  • Pediatric Orthopedics
  • Rehabilitation Medicine
  • Movement Science

Background:

  • The Gillette Functional Assessment Questionnaire (FAQ) is a widely used tool for assessing functional abilities in children.
  • Understanding the psychometric properties of the FAQ 22-item skill set is crucial for accurate assessment of locomotor skills.
  • Previous analyses have not fully explored the dimensionality and item-level characteristics of the FAQ 22-item skill set.

Purpose of the Study:

  • To determine the dimensionality and item-level properties of the Gillette Functional Assessment Questionnaire (FAQ) 22-item skill set.
  • To validate the unidimensionality of the skill set using factor analysis.
  • To assess item difficulty, information, and content coverage using Rasch analysis.

Main Methods:

  • Retrospective review of parent-reported FAQ 22-item skill set data from 485 individuals.
  • Factor analyses to validate unidimensionality.
  • Rasch analyses to determine item difficulty, item and test level information, and content coverage.
  • Differential item functioning (DIF) analysis based on sex, diagnosis, and age.

Main Results:

  • The FAQ 22-item skill set demonstrated a unidimensional structure with good item fit statistics.
  • No floor or ceiling effects were observed, indicating comprehensive measurement across ability levels.
  • Differential item functioning (DIF) was noted for age (7 items), diagnosis grouping (4 items), and sex (1 item).
  • Score estimate precision was adequate in the mid-range of abilities.

Conclusions:

  • The FAQ 22-item skill set is a hierarchical set of interval-scaled items.
  • It is suitable for measuring locomotor skill ability in children.
  • The findings support the use of the FAQ 22-item skill set as a reliable measure of functional abilities.
