Scale-Description

The ESSS is a psychometric tool used to evaluate aspects of an individual’s perception of their own self. It focuses on the subjective sense of self, including characteristics such as self-coherence, identity stability, and a sense of control or autonomy.
This tool can be used for:
Assessing the internal coherence of an individual’s identity.
Detecting disturbances in the sense of self related to psychological conditions such as personality disorders, mood disorders, or traumatic experiences.
Studying the connection between the sense of self and mental health.

Data Analysis and Usage

The ESSS relies on data collected from participants’ responses to a questionnaire. The data can be analyzed using statistical techniques such as factor analysis or reliability analysis to check the scale’s validity and reliability. Often, responses to the scale’s questions are scored using Likert scales, allowing for quantitative data analysis.

Purpose

The primary goal of the ESSS is to provide an assessment tool for the subjective experience of the self. Its purpose is to measure dimensions such as self-perception, the continuity of self over time, autonomy, and identification with the personal “I.”

Calibration

The calibration of the ESSS typically involves the use of standard psychometric techniques:
Reliability analysis, e.g., calculating Cronbach’s alpha to measure the internal consistency of subscales.
Factor analysis to identify the dimensions underlying the data and ensure the validity of the constructs.
Cross-validation of the results across different populations to ensure that the scale works reliably in other groups.
