Description[edit | edit source]

Dyspnoea represents one of the most frequent cardinal symptoms globaly. It is a sensation of lacking of the air and of not being able to breathe normally. Dyspnoea management questionnaire was developed in USA to measure the effect of lung rehabilitation and change over time in patients with COPD.Dyspnoea Management Questionnaire (DMQ) used in clinical and research settings for measuring treatment outcomes for patients with chronic obstructive lung disease (COPD).[1] The Dyspnoea management questionnaire was developed to be both a clinical and a research outcome scale to measure the effectiveness of multi-disciplinary treatments that aim to reduce the emotionally distressing and disabling responses to dyspnea and promote adaptive coping for adults with COPD.[1] There are three different versions DMQ-30 DMQ-56 and DMQ-CAT

Method of Use[edit | edit source]

  • The dyspnoea management questionnaire DMQ consists of five theoretical dyspnea dimensions:
  1. dyspnea intensity,
  2. dyspnea anxiety,
  3. activity avoidance,
  4. activity self-efficacy,
  5. satisfaction with strategy use.
  • The dyspnoea management questionnaire (DMQ) uses a 7-point Likert response scale that ranges from 0 to 6 with higher scores representing better dyspnea-related function. 
  • the activity avoidance scale of the dyspnoea management questionnaire (DMQ) ranges from (6=never) to (0=all the time)
  • To calculate each subscale score, raw values for items are summed and then divided by the number of items in the subscale to obtain a mean score.

Dyspnoea Management Questionnaire(DMQ-30)[edit | edit source]

  • Data from qualitative interviews, literature review on the areas of breathlessness, anxiety, avoidance behaviour, functional status, health related quality of life, user satisfaction, and lung rehabilitation, as well as a review of other measurement instruments, made up the basis for the development of DMQ-30.
  • The resulting DMQ is a 30-item scale that measures 5 conceptually derived dimensions: dyspnea intensity, dyspnea-related anxiety, fearful activity avoidance, self-efficacy for activity, and satisfaction with strategy use. It has a 7-point Likert-type scale and third Flesch-Kincaid reading grade level.
  • .The DMQ addresses the need for a more comprehensive, multidimensional assessment of dyspnea, especially for anxious patients with COPD,
  • in order to better guide the appropriate application of dyspnea management interventions and measure pulmonary rehabilitation outcomes.
  • [2]In 2006 research panel of 12 experts supported the content validity of the DMQ. It showed high internal consistency (alpha = .87 to .96) and test-retest reliability over 2.5 weeks (intraclass correlation coefficient = 0.71 to 0.95)

Dyspnoea Management Questionnaire(DMQ-56)[edit | edit source]

  • The DMQ demonstrated acceptable levels of reliability and validity for measuring multidimensional dyspnea outcomes after medical, psychological, and behavioral interventions for adults with COPD..
  • The reserch shows DMQ-56 good internal consistency reliability (α = 0.85-to 0.96) and good preliminary test-retest reliability over a 3-week interval (ICC = 0.69-0.92).[3]

Dyspnoea Management Questionnaire-Computer adaptive test (DMQ-CAT)[edit | edit source]

  • The multidimensional assessment approach afforded by the DMQ-CAT can potentially advance the measurement of patient-reported changes in dyspnea following treatment.
  • It appears that the DMQ-CAT can reliably, validly, and efficiently differentiate distinct sensory, psychological and behavioral domains of dyspnea to improve the measurement of psychosocial, pharmacologic, and pulmonary rehabilitation treatment effects in adults with COPD.[4]
  • An advantage of the DMQ-CAT is that it reduces respondent burden by minimizing the number and tailoring the content of dyspnea items to ensure that only the most relevant and informative items are administered, thereby increasing its usability in busy clinical and research[5]
