Self-Report Tests of Personality

458
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.

Area of Science:

  • Public Health
  • Epidemiology
  • Behavioral Science

Background:

  • U.S. invested over $1 billion in COVID-19 testing and diagnostics.
  • The impact of testing on transmission-related behaviors remains under-assessed.

Purpose of the Study:

  • To assess the impact of COVID-19 testing on individual behaviors related to disease transmission.
  • To evaluate the role of testing in preventing severe health outcomes.

Main Methods:

  • Utilized crowdsourced data from the Outbreaks Near Me platform (November 2022 - September 2023).
  • Collected data on actions taken by individuals after testing positive for COVID-19.
  • Analyzed covariates including age, sex, race, comorbidities, vaccination status, and healthcare occupation.

Main Results:

  • 75% of participants reported at least two precautions to prevent COVID-19 spread.
  • 81% of those taking precautions intended to continue until testing negative or 10 days post-infection.
  • 48% sought medical care or therapeutics after a positive test, indicating testing's impact on health outcomes.

Conclusions:

  • A high proportion of individuals adopted protective behaviors and sought medical care post-COVID-19 diagnosis.
  • Behavioral changes were more pronounced in older adults, females, boosted individuals, and those with multiple comorbidities.
  • Findings support continued investment in testing and diagnostics for pandemic preparedness and response.
