Podsumowanie	The PSRS is an 8-item self-report scale measuring individual differences in perceived reactivity to stressful situations—the subjective sense of being easily stressed, emotionally reactive, or overwhelmed by demands. Developed by Hewitt and colleagues in the context of perfectionism and stress research, the PSRS captures a trait-like tendency toward heightened stress reactivity, often termed stress sensitivity or emotional reactivity. The scale is used in clinical and research settings to identify individuals at risk for stress-related psychopathology and to measure changes in stress responsiveness over time.	The IES-R is a 22-item self-report scale measuring subjective distress from a specific traumatic event. Developed by Weiss and Marmar in 1997 as a revision of the original 1979 Impact of Event Scale, it assesses posttraumatic stress symptoms along three core dimensions: intrusion, avoidance, and hyperarousal. The scale is widely used in clinical research, trauma assessment, and treatment monitoring.
