The original Perceived Stress Scale (PSS) is a 14-item self-report measure designed to assess the extent to which individuals judge their life circumstances as stressful.1
PSS items are not bound to a specific life event or clinical condition; therefore, assessment of stress is broad, allowing for use in diverse populations and across different contexts.2
Respondents are asked to contemplate the past month and then indicate how often they have felt that their lives are unpredictable or uncontrollable using a 5-point Likert-type scale, with a response set ranging from 0 (never) to 4 (very often). Although the PSS-14 has demonstrated adequate psychometric properties, 2 short-form versions have also been developed: a 10-item version,2., 3.
derived from the 14-item scale using factor analysis techniques, and a 4-item version for use in brief interview situations.1., 4.
Exploratory and confirmatory factor analyses support a 2-factor structure, with the first encompassing positive, coping-related questions and the second involving negatively worded, stress-related questions.5
The PSS has shown to be a reliable and valid measure of perceived psychosocial stress,6
demonstrates adequate to excellent criterion and construct validity with similar measures of life experience and stress,1
and has been used in a diverse range of clinical and nonclinical populations.2., 3., 4., 5., 6., 7., 8., 9., 10.
In addition, versions of the PSS have been translated and validated in more than 25 languages.11
This Rehabilitation Measures Database summary provides a review of the psychometric properties of the PSS in people with spinal cord injury, including reliability, validity, standard error of measurement, minimum detectable change, and interpretation of the results.
