The Chronic Respiratory Disease Questionnaire (CRQ) is the most commonly used disease specific measurement tool to assess HRQL in patients with chronic . Due to their widespread and thorough validation, the following questionnaires are recommended: Chronic Respiratory Disease Questionnaire (CRDQ or CRQ) . To measure health related quality of life in patients with chronic respiratory disease.

Outcomes in Cardiopulmonary Physical Therapy: Chronic Respiratory Disease Questionnaire (CRQ)

The self-administered questionnaire is also reported to have high reliability. Available applications through flintbox: Guyatt et al 2 found that the CRQ has similar responsiveness to the Transitional Dyspnea Index and superior responsiveness to the Rand dyspnea questionnaire, the oxygen cost diagram, and the Rand physical and emotional function questionnaires. High response rates to this type of questionnaire have been achieved in outpatient settings; however, the interview form quesyionnaire quite expensive 13 and time consuming.

Please review our privacy policy. Recently, clinicians and payers are recognizing that physiological measures do not necessarily relate to function, and functional outcomes need to be measured independently. A comparison of three disease-specific and two generic health-status measures to evaluate the outcome of pulmonary rehabilitation in COPD. The self administered CRQ is a written version of the tool that the patient completes independently; the wording, content, structure and scoring are exactly consistent with the original version.

Test-retest reliability of the CRQ has been found to be high. This article resiratory been cited by other articles in PMC. In order for a test to be useful in the clinic, the instrument must be consistent in its measurements.

In comparison with global ratings of change, the CRQ was found to have moderate to high correlations 2 which were significantly stronger than those of generic health measures. The resulting questionnaire contains 20 items that are believed to represent areas of dysfunction that are most significant to this patient population.

In the fatigue domain, which was not reliable as a whole, 3 of the 4 individual items showed insignificant correlation. The panel’s levels for detecting small, moderate, and large changes were slightly higher than previously determined levels based on patient-perceived change. List per page or see all.


Eur Resp J Jan;25 1: The resiratory has shown the CRQ to be a valid test of HRQL, with moderate to strong correlations with questoinnaire ratings as well as both generic and disease specific convergent measures. Important considerations for questionnaires such as CRQ include the ease and cost of administration. He also found that the MCID correlated with a change of 0. Fatigue domain scores also improved as shuttle walk test scores improved. From these results, the researchers concluded that the CRQ has excellent reliability.

Chronic Respiratory Disease Questionnaire-CRQ

Measuring health related quality of life. The respiratoy interviewer administered CRQ requires 20 to 25 minutes for the first administration and 10 to 15 minutes for respiratroy follow up visit. Wyrwich et al 29 described the importance of determining the physician’s definition of the MCID in order to better understand and support the use of HRQL measurement tools in the clinic. The expert panel recommended that MCID be associated with a change greater than 2 points in the domain score.

The CRQ scores also follow predicted tracts and correlate well with clinical status.

The Chronic Respiratory Disease Questionnaire has been supported in the evidence to be one respiratroy the most optimal instruments to measure HRQL in patients with chronic respiratory disease.

High reliability was found for the domains of dyspnea, mastery, and emotional functioning with scores as follows: Measuring patient and clinical perspectives to evaluate change in health-related quality of life among patients with chronic obstructive pulmonary disease. Guyatt et al 21 determined that the CRQ dyspnea domain had a correlation of 0. Further, Harper et al 13 reported that CRQ scores remained stable over time in clinically stable patients while CRQ scores improved in patients who were expected to have clinical improvements.

Guyatt’s study illustrates that the CRQ has adequate responsiveness to detect highly significant differences, even within small numbers of subjects. Using 2 rounds of the Delphi method, one in person meeting and a repetitive enhancement respirator for circulating and correcting the final report, they were able to determine the values of change for each domain that would result in a small, moderate, and large MCID.


Validity was determined to be strong; no statistically significant difference between the 2 instruments was found in the fatigue and mastery domains, and the small mean differences found in the dyspnea 0. There was good agreement between the predicted and actual correlations in both these cases. A novel, short, and simple questionnaire to measure health-related quality of life in patients with chronic obstructive pulmonary disease.

Chronic Respiratory Disease Questionnaire (CRQ)

The total domain and the emotion domain scores were determined to be the most responsive to these changes. The CRQ are validated and reliable quality of life measures for patients with chronic airflow limitations. Available literature has repeatedly illustrated the ability of the CRQ to generate results that are reproducible in a variety of settings.


Subsequent versions of the test have been developed to improve time and ease of administration. Cardiopulm Phys Ther J.

The evidence has shown that the CRQ is a valid tool to assess health related quality of life in patients with chronic respiratory disease. Reliability and validity of the chronic respiratory questionnaire CRQ Thorax.

Williams et al 26 used respirayory response means to assess the sensitivity and also found the CRQ-SR to be highly sensitive across all domains of the questionnaire indicating that it is able to detect changes following a treatment program.

This paper describes the current research regarding the reliability, validity, responsiveness, minimally clinical important difference, and suggested use of the Chronic Respiratory Disease Questionnaire in clinical practice. Guyatt et al 2 the authors of the CRQ, established the test-retest reliability of the tool prior to its release.

For this reason, it is important to evaluate the outcomes of various interventions to ensure that patients are receiving the most efficient and best available care. Lower correlation scores were noted quesyionnaire the second 6 month period; however, they were questonnaire significant enough to indicate that bias existed between assessments.
