Description

The Extraversion vs. Introversion Scale [AQ-20] is a psychometric tool designed to assess the dimensions of extraversion and introversion in an individual. This scale is based on the psychological theory of the Big Five and aims to understand how people respond to and interact with their social environment.

Purpose

The primary goal of the Extraversion vs. Introversion Scale [AQ-20] is to measure an individual’s tendency toward extraversion or introversion. This tool is used in psychological research and clinical assessment to help understand individual differences in social behavior and interaction with the environment.

Analysis

The AQ-20 scale consists of 20 statements that assess the two main dimensions of personality:
Extraversion:
The tendency toward sociability, activity, and preference for external stimulation.
Example statements: “I enjoy being around many people,” “I feel energetic and full of vitality when I am with others.”
Introversion:
The tendency toward inner thought, preference for solitude, and calm activities.
Example statements: “I prefer to spend time alone,” “I feel comfortable when I am by myself.”
Participants are asked to respond to each statement using a Likert scale ranging from 1 (Strongly Disagree) to 5 (Strongly Agree).

Scoring

The total score for extraversion and introversion is calculated by summing the scores of the statements related to each dimension. Higher scores on the extraversion scale indicate a stronger tendency toward extraversion, while higher scores on the introversion scale indicate a stronger tendency toward introversion.
