It was introduced in 1995 and has since been used in a variety of experimental and clinical studies. The O-LIFE is a tool with 104 items in the Yes/No response format, although a shorter version (sO-LIFE) can be used as well with only 43 items. [2] It has been used, for instance, in several studies assessing schizotypy in relation to Kamin ...
In psychometrics, item response theory (IRT, also known as latent trait theory, strong true score theory, or modern mental test theory) is a paradigm for the design, analysis, and scoring of tests, questionnaires, and similar instruments measuring abilities, attitudes, or other variables.
An item bank will not only include the text of each item, but also extensive information regarding test development and psychometric characteristics of the items. Examples of such information include: [1] Item author; Date written; Item status (e.g., new, pilot, active, retired) Angoff ratings; Correct answer; Item format; Classical test theory ...
A self-report inventory is a type of psychological test in which a person fills out a survey or questionnaire with or without the help of an investigator. Self-report inventories often ask direct questions about personal interests, values, symptoms, behaviors, and traits or personality types.
The PANAS for Children (PANAS-C) was developed in an attempt to differentiate the affective expressions of anxiety and depression in children. The tripartite model on which this measure is based suggests that high levels of negative affect is present in those with anxiety and depression, but high levels of positive affect is not shared between the two.
The samples of behavior must be reasonably representative of the behavior in question. The samples of behavior that make up a paper-and-pencil test, the most common type of psychological test, are written into the test items. Total performance on the items produces a test score.
Within psychometrics, Item analysis refers to statistical methods used for selecting test items for inclusion in a psychological test. The concept goes back at least to Guildford (1936). The process of item analysis varies depending on the psychometric model. For example, classical test theory or the Rasch model call for different procedures ...
Scholarly work has noted the problematic nature of using the terms “emotion”, “affect” and “mood” interchangeably. [1] A lack of thorough understanding of these concepts could influence the choice of measures used in assessing the emotional components of interest in a study, leading to a less optimal research result.
