The Perceived Stress Scale (PSS-10) is an instrument that can be used to measure stress levels in children (age 12 and above) and adults. Through 10 items using a five point likert scale from “never” to “very often”, the PSS assesses an individual’s perception of life as unpredictable, uncontrollable and overloading over the previous month.
10 Scales/Subscales: “in the last month…”
- How often have you been upset because of something that happened unexpectedly?
- How often have you felt that you were unable to control the important things in your life?
- How often have you felt nervous and stressed?
- How often have you felt confident about your ability to handle your personal problems?
- How often have you felt that things were going your way?
- How often have you found that you could not cope with all the things that you had to do?
- How often have you been able to control irritations in your life?
- How often have you felt that you were on top of things?
- How often have you been angered because of things that happened that were outside of your control?
- How often have you felt difficulties were piling up so high that you could not overcome them?
Administration Format: self-report questionnaire
Administration Format: 5-10 minutes
Reliability (Lee 2012; Kechter 2019; Liu 2020):
- Internal Consistency: good internal consistency indicated in both adult populations, university student populations, American adolescents, and Chinese adolescents.
- Test-Retest: adequate in adults over a 2 and 4 week delay.
Validity (Lee 2012; Liu 2020; Sood 2013):
- Convergent Validity: scores correlated positively with stress in Chinese adolescents
- Concurrent Validity: scores correlated positively with measures of anxiety and depression in adult populations, university student populations, and adolescents.
