PSWQ: Penn State Worry Questionnaire

What this assessment is

The Penn State Worry Questionnaire, or PSWQ, is a 16-item self-report measure of a person's general tendency to worry.

Thomas Meyer and colleagues introduced it in a 1990 development study. They designed the measure to capture excessive, persistent, and hard-to-control worry without tying it to one subject.

The PSWQ measures a trait-like pattern. It is not a checklist of generalized anxiety disorder symptoms and does not provide a diagnosis.

Who it was designed for

The original research used university students and a small clinical group with generalized anxiety disorder. Later studies tested the scale in community, medical, older-adult, and clinical samples.

Scores differ across those groups.

Age, health, language, setting, and the reason for assessment can affect a result. A cutoff studied in one population should not be applied automatically to another.

The standard PSWQ is an adult measure. Versions developed for children, older adults, and shorter administration have separate evidence and score ranges.

How it is administered

The standard PSWQ is self-completed. It contains 16 statements with five response levels.

It asks what is generally typical of the respondent. It does not use a fixed period such as the past week or past two weeks.

Timeframe matters.

That makes the PSWQ different from recent-symptom screens. The GAD-7 asks about generalized-anxiety symptoms over the past two weeks, while the PSWQ focuses on a broader tendency to worry.

Use one complete version. Do not add a recent timeframe to the standard form and then compare the total with published PSWQ results.

What it measures

The PSWQ focuses on the intensity, frequency, and controllability of worry. It does not ask the respondent to divide worry into topics such as work, health, family, or money.

This gives one general worry total.

The scale includes statements worded in both directions. Research has found that the negatively worded items can behave as a method factor in some populations. That does not change the standard scoring rule, but it can affect measurement in specific groups.

The total stays single.

The PSWQ does not measure every physical symptom of anxiety, panic attacks, phobias, compulsions, or trauma symptoms.

How scoring works

Each response scores from 1 to 5. Five negatively worded items are reverse scored. Add all 16 corrected values.

The total runs from 16 to 80. Higher totals indicate more reported worry.

Use the reverse-scoring step. A straight sum without it gives the wrong result.

An independent scoring analysis confirms the 16-to-80 range and the five reverse-scored items. It also found that those items behaved differently in its cancer sample.

Complete all 16 responses when possible. No single missing-response replacement rule applies across every study and setting.

How to interpret a PSWQ score

Interpret the total as a continuous measure of worry. Higher scores indicate more frequent or difficult-to-control worry.

There is no universal clinical cutoff.

Context decides which comparison is defensible.

Published studies have used decision points near 50, 62, or 65 in different populations. Those numbers answer different research questions. They do not form one accepted set of low, moderate, and high bands.

Compare a result with evidence from a similar population. For repeated measurement, use the same version and administration method and review what changed in the person's circumstances.

Do not diagnose generalized anxiety disorder from the score alone.

What the score cannot tell you

The PSWQ cannot identify the cause or subject of worry. It cannot separate generalized anxiety from depression, trauma, obsessive-compulsive symptoms, illness-related concern, or current stress.

It also cannot show how much worry impairs work, relationships, sleep, or physical health unless those areas are assessed separately.

A low total does not rule out severe anxiety of another kind. A high total does not establish one diagnosis or treatment need.

Use the result as one part of an assessment.

Evidence and limitations

The original study found strong internal consistency, stability over time, and expected relationships with other anxiety measures. The PSWQ also distinguished clinical groups in early research.

Later studies have questioned whether all 16 items form one clean factor in every population. Short forms such as the eight-item PSWQ-A were created for particular settings, but they do not share the standard 16-to-80 range.

Do not merge versions.

The ranges differ.

Translations need their own validation. Before comparing totals, confirm the exact version, language, response scale, and scoring method.
