Self-Report Tests of Personality01:22

Self-Report Tests of Personality

348
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.

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Self-Presentation: Self-Monitoring and Self-Handicapping

39.0K
People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

Self-Schemas02:16

Self-Schemas

31.1K
In general, a schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

Deindividuation00:57

Deindividuation

26.4K
Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.

Five-Factor Theory of Personality01:29

Five-Factor Theory of Personality

920
The five-factor model, often called the Big Five personality traits, is widely accepted in psychology as a comprehensive framework for understanding personality. 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...

Area of Science:

  • Psychological assessment
  • Mental health research
  • Clinical psychology

Background:

  • Suicidal narratives are complex and require validated instruments for accurate measurement.
  • The Abbreviated Suicidal Narrative Inventory (SNI-38) is a tool used to assess these narratives.
  • Adapting and validating instruments for specific cultural contexts, like Brazil, is crucial for effective mental health research.

Purpose of the Study:

  • To evaluate the psychometric properties of the Brazilian version of the Abbreviated Suicidal Narrative Inventory (SNI-38).
  • To test the factor structure, reliability, and validity of the SNI-38 in a Brazilian population.

Main Methods:

  • An anonymous online questionnaire including the SNI-38 and other self-report measures was administered to 2,660 Brazilian participants.
  • Confirmatory factor analysis (CFA) was used to assess the factor structure.
  • Internal consistency and convergent validity were examined against measures of stressful life events, suicide crisis syndrome, suicidal ideation, and suicide attempts.

Main Results:

  • The eight-factor model of the SNI-38 demonstrated good model fit, with all items loading significantly onto their respective factors.
  • Reliability was good to high for most subscales.
  • The SNI-38 subscales showed significant positive correlations with indicators of suicide risk, including suicidal ideation and attempts.

Conclusions:

  • The Brazilian version of the SNI-38 is a valid and appropriate instrument for measuring suicidal narratives in Brazilian individuals.
  • These findings support the use of the SNI-38 in clinical and research settings within Brazil.
  • Further research may explore its application in diverse Brazilian populations.
