Analysis

The Perceived Stress Scale – 4 Items (PSS-4) is a shortened version of the original Perceived Stress Scale, designed to assess the degree to which individuals perceive their life situations as stressful. It focuses on the lack of control, the unpredictability of events, and the general level of anxiety experienced by participants during the past 4 weeks.

Purpose

The goal of the PSS-4 is to provide a brief yet reliable measure of perceived stress, allowing for quick assessment of stress levels in various research and clinical applications.

Scoring Method

The PSS-4 includes 4 statements that evaluate perceived stress on a 5-point Likert scale. These statements focus on how often participants feel that they cannot control important things in their lives and how often they feel nervous or under pressure.

Reliability

Although the PSS-4 is shorter, it aims to maintain a satisfactory level of reliability, usually with a Cronbach’s alpha coefficient above 0.70.
