Protocol Name from Source:

Perceived Stress Scale

Availability:

Publicly available

Description:

This 10-item self-administered scale is used to measure an individual’s level of perceived stress in the past month. As a result, it measures only current (not chronic) levels of perceived stress. The response options for each feeling or thought indicate the frequency with which it occurred: 0 = Never; 1 = Almost Never; 2 = Sometimes; 3 = Fairly Often; 4 = Very Often.

Protocol:

The Perceived Stress Scale includes 10 questions about the person's feelings and thoughts during the past month. The response options for each feeling or thought indicate the frequency with which it occurred: 0 = Never; 1 = Almost Never; 2 = Sometimes; 3 = Fairly Often; 4 = Very Often. Scoring instructions are available on the Carnegie Mellon website.

Personnel and Training Required

The interviewer must be trained to conduct personal interviews with individuals from the general population. The interviewer must be trained and found to be competent (i.e., tested by an expert) at the completion of personal interviews. The interviewer should be trained to prompt respondents further if a "don’t know" response is provided.

Equipment Needs

These questions can be administered in a computerized or noncomputerized format (i.e., paper-and-pencil instrument). Computer software is necessary to develop computer-assisted instruments. A laptop computer/handheld computer will be needed to administer a computer-assisted questionnaire.

Life Stage:

Adult

Specific Instructions:

The 10-item Perceived Stress Scale (PSS) and scoring are available from Dr. Cohen’s laboratory through the Carnegie Mellon University Department of Psychology website. Permission for use of scales is not necessary when use is for nonprofit academic research or educational purposes.

The PSS is not a diagnostic instrument, and there are no cut-offs for classification of responders into "high," "medium," or "low" stress. It is generally used as an ordinal scale or count measure.

Psychometric properties have not been collected on other time periods.

The PSS was designed for use with community samples with at least a junior high school education.

There are also 4- and 14-item versions of this scale available. The 10-item scale is recommended because it has been psychometrically tested, has been used in large population-based studies, and represents low respondent burden.

Definition

This is a measure of the degree to which situations in one’s life in the past month are appraised as stressful.

Purpose

The Perceived Stress Scale (PSS) is a nonspecific stress appraisal. The results may be used to examine the association between stress and the etiology of disease and/or behavioral disorders. Perceived stress has been associated with cardiovascular disease morbidity and mortality and premature death. PSS has also been seen as relevant to health and illness behaviors (e.g., the use of formal health care).

Selection Rationale

The Perceived Stress Scale (PSS) is the most widely used index of perceived stress. The scale has good reliability and validity and has been used in many settings.
