Scale-Description

The Stress Observation Scale (SOS-25) is a psychometric tool designed to assess the level of stress experienced by an individual. This scale consists of 25 questions that examine symptoms and reactions related to stress, allowing an understanding of how the person reacts to stressful situations.
The SOS-25 covers various dimensions of stress, such as:
Physical symptoms: Feelings of fatigue, muscle tension, difficulty sleeping.
Emotional symptoms: Worry, irritability, sense of helplessness.
Behavioral reactions: Avoidance of activities, reduced performance in work or social settings.
The scale can be completed either by the individual themselves or by an observer who records their reactions to stressful situations.

Data Analysis and Usage

The data collected from the SOS-25 are analyzed to identify the level and sources of stress experienced by the individual. The key statistical analyses used include:
Reliability analysis to measure the internal consistency of the scale by calculating Cronbach’s alpha.
Factor analysis to identify the main dimensions of stress that the scale measures.
Correlation analysis to examine the relationship between stress and other psychological variables, such as depression, resilience, or quality of life.
The results from the SOS-25 are used in clinical settings to diagnose and monitor stress, as well as in research studies to understand the impact of stress on mental and physical health.

Purpose

The primary goal of the SOS-25 is to assess the level of stress experienced by an individual and identify the main sources and symptoms of stress. This tool can be used to:
Identify individuals experiencing high levels of stress who may need intervention or support.
Evaluate the effectiveness of stress management strategies or therapeutic interventions.
Promote research on the impact of stress on various aspects of life, such as work, relationships, and mental health.

Calibration

The calibration of the SOS-25 includes:
Reliability analysis to determine the consistency and stability of responses in different situations.
Confirmatory factor analysis to ensure that the scale accurately measures the dimensions of stress.
Cross-validation in various populations to ensure the tool’s generalizability and validity.
