[Self-evaluation questionnaires--factorial structure and indications for general practice]
Summary
This study validated personality inventories for clinical and non-clinical use. The Freiburg Personality Inventory (FPI) and Giessen-Test (GT) showed strong factorial structures, proving useful for diverse applications.
Area of Science:
- Psychometrics
- Clinical Psychology
- Personality Assessment
Context:
- Evaluation of psychometric instruments is crucial for accurate psychological assessment.
- Distinguishing between clinical and non-clinical populations requires validated measurement tools.
- Understanding the dimensionality of self-rating inventories aids in their practical application.
Purpose:
- To examine the dimensionality of five self-rating inventories: Basel Mood Inventory (BBI), Freiburg Personality Inventory (FPI), Giessen-Test (GT), Complaint-List (HHM), and Paranoid-Neuroticism-Depression-Scale (PND-S).
- To assess the practical applicability of these inventories in both clinical and non-clinical settings.
- To verify the factorial structure of the inventories and inform revisions.
Summary:
- The Freiburg Personality Inventory (FPI) and Giessen-Test (GT) demonstrated robust factorial structures, confirming their utility as versatile personality inventories for both clinical and non-clinical populations.
- The Paranoid-Neuroticism-Depression-Scale (PND-S) revision justified removing the neuroticism dimension; the new PD and PD' versions are valuable for group differentiation in depression and schizophrenia studies.
- The Basel Mood Inventory (BBI) effectively measures a mood-drive dimension, suitable for independent or combined use with personality inventories in longitudinal studies. The Complaint-List (HHM) measures mood states but lacks differentiation.
Impact:
- Validated personality and mood inventories enhance diagnostic accuracy and facilitate effective treatment planning in clinical psychology.
- The findings support the use of revised and established psychometric tools in longitudinal and cross-sectional research for better understanding of psychological constructs.
- This research contributes to the refinement of psychological assessment instruments, improving their reliability and applicability in diverse research and clinical contexts.

Surveys
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.
Factorial Design
Factorial Analysis is an experimental design that applies Analysis of Variance (ANOVA) statistical procedures to examine a change in a dependent variable due to more than one independent variable, also known as factors. Changes in worker productivity can be reasoned, for example, to be influenced by salary and other conditions, such as skill level. One way to test this hypothesis is by categorizing salary into three levels (low, moderate, and high) and skills sets into two levels (entry level...
Self-Evaluation: Self-Enhancement and Self-Verification
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
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.
Social Foundations of Self III: Self-Evaluation
Self-evaluation is the process by which individuals assess their abilities, behaviors, and characteristics based on feedback from others. Charles H. Cooley observed that a person’s self-perception is primarily influenced by how others see and judge them. He suggested that individuals form their identities based on their interpretations of others' reactions. As a result, social interactions play a crucial role in shaping self-esteem and personal identity. These external evaluations often blend...
Strategies of Self-Presentation III: Self-Monitoring
Self-monitoring is a central construct in understanding individual differences in self-presentation strategies across social contexts. It refers to how individuals observe, regulate, and control their expressive behavior and self-presentation following situational cues. Self-monitoring reflects a person's sensitivity to social appropriateness and willingness to adapt behavior to fit varying interpersonal demands.High vs. Low Self-Monitoring IndividualsIndividuals high in self-monitoring are...
