Self-Report Tests of Personality

405
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.

Trait Theory by Gordon Allport

Gordon Allport, often regarded as the father of American personality psychology, developed a theory that emphasized the importance of understanding people in their present lives rather than focusing on their past, as psychoanalysis did. Allport believed that personality should be studied in healthy, well-adjusted individuals rather than those with psychological problems. He was particularly interested in defining traits, which he saw as fundamental mental structures that guide behavior across...

These five traits — Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism — are often remembered using the acronym OCEAN.
Openness reflects creativity, curiosity, and openness to new experiences. Individuals scoring high in openness are imaginative, have a wide range of interests, and are independent...

Cultural Influences on Personality

Individualist and collectivist cultures emphasize different core values, shaping personality in distinct ways. In individualist cultures, such as those in the United States, England, and Australia, people prioritize independence, competition, and personal achievement. These societies tend to promote self-focused traits, with individuals often reporting higher levels of self-esteem. In contrast, collectivist cultures, commonly found in regions like Asia, Africa, and South America, emphasize...

Area of Science:

  • Ophthalmology
  • Psychiatry
  • Psychology

Background:

  • Keratoconus (KC) is a progressive eye condition affecting corneal shape.
  • Understanding the psychological profile of KC patients is crucial for comprehensive care.

Purpose of the Study:

  • To investigate and compare personality traits in patients with keratoconus versus healthy controls.
  • To identify potential psychological factors associated with keratoconus.

Main Methods:

  • A case-control study involving 60 participants (30 KC, 30 controls) aged 18-30.
  • Utilized the National Eye Institute Visual Function Questionnaire-25 (NEI VFQ-25) for quality of life assessment.
  • Administered psychiatric assessments including SCID-5, SCL-90, TEMPS-M, and NEO-FFI.

Main Results:

  • KC patients reported significantly lower quality of life across all NEI VFQ-25 domains.
  • 30% of KC patients were diagnosed with cluster C personality disorders, a nine-fold increase compared to controls.
  • Keratoconus patients displayed heightened psychosomatic symptoms and a neurotic temperament.

Conclusions:

  • Individuals with keratoconus may possess dysfunctional coping mechanisms and specific personality traits.
  • These psychological factors might be present from the initial clinical presentation of KC.
  • Ophthalmologists should consider the mental and emotional well-being of KC patients during management.
