Self-Report Tests of Personality

309
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).

One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

This test later evolved into the Wechsler Adult Intelligence...

Area of Science:

  • Psychology
  • Health Sciences
  • Measurement

Background:

  • Wellness is linked to medical and mental health, but a comprehensive measure is lacking.
  • The Wellness Inventory was developed iteratively with stakeholders for face and content validity.

Purpose of the Study:

  • To examine the psychometric properties of the Wellness Inventory.
  • To assess the construct validity and reliability of the Wellness Inventory.

Main Methods:

  • Data from 3,446 university students, faculty, and behavioral health providers were analyzed.
  • Exploratory and confirmatory factor analyses were used to determine the factor structure.
  • Test-retest reliability, convergent, and discriminant validity were assessed.

Main Results:

  • Factor analyses supported a one-factor model with 54 items.
  • The revised instrument showed good fit, internal consistency, and test-retest reliability.
  • Reasonable construct validity was established for the Wellness Inventory.

Conclusions:

  • The Wellness Inventory is a psychometrically sound and comprehensive tool for assessing wellness.
  • Findings suggest wellness is a holistic, general construct, supported by a single dimension.
  • The inventory has implications for health promotion, prevention research, and clinical practice.
