Analysis

The Self-Construal Scale (SCS) is a psychometric tool developed to measure the way people perceive and define themselves in relation to others. Specifically, it examines the dimension of individual (independent) and interpersonal (interdependent) self-construal. The tool consists of various statements that assess how often or how strongly participants agree with certain views or behaviors related to their self-construal.

Purpose

The main purpose of the Self-Construal Scale is to provide a clear and accurate measurement of how people see themselves—as autonomous and independent, or as connected to and dependent on their relationships with others. This understanding can be applied in various fields of psychological research and practice, such as cross-cultural psychology, personality psychology, and the social sciences. In addition, the SCS helps to understand how different types of self-construal may influence people’s behaviors, attitudes, and psychological states.

Calibration

The calibration of the Self-Construal Scale is carried out through a series of statements to which participants are asked to indicate their degree of agreement or disagreement using a Likert scale, usually five-point or seven-point. The scale evaluates two main dimensions: independent self-construal and interdependent self-construal. Each statement is scored separately, and then the scores are combined to calculate overall scores for the two dimensions. These overall scores are used to classify participants in terms of their tendency toward independence or interdependence.
