Self-Report Tests of Personality

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.

Personality Theory by Eysenck and Eysenck

Hans and Sybil Eysenck developed a widely recognized theory of personality, which emphasizes the role of temperament and genetically based differences in shaping individual traits.

In contrast to traits, states are...

Background:

The alternative model of personality disorders is recognized, but overlap between personality functioning, maladaptive traits, and normal traits needs more research.
Longitudinal evidence and generalizability of existing findings on these associations are limited.

Purpose of the Study:

To conduct a conceptual replication of previous findings on personality functioning and traits.
To investigate associations and distinctions among personality functioning, normal-range traits, and maladaptive traits in a Norwegian community sample.
To extend prior research to a new population and methodological context.

Main Methods:

A preregistered study with 1,418 participants from a Norwegian community sample.
Longitudinal data collected across 4 waves over 6 months.
Conceptual replication of 11 preregistered hypotheses from a prior study.

Main Results:

Findings largely replicated the pattern of a previous study.
Systematic differences were observed in the distributions and longitudinal properties of personality functioning and traits.
Maladaptive traits were predicted by both personality functioning impairments and normal-range personality traits.

Conclusions:

Results provide further longitudinal support for similarities and distinctions between personality functioning and trait dimensions within the alternative model of personality disorders.
This replication strengthens evidence for the robustness and generalizability of conclusions regarding personality functioning and traits.
The study highlights shared and unique contributions of personality functioning and traits to maladaptive traits.
