Key Descriptions

  • Patient-reported outcome measure, which can be self-administered or administered as a patient interview
  • Contains 15 items grouped into four domains: self-care, household activities (domestic), physical, and leisure activities
  • Responses for each item range from 0-5, with 0 indicating “wouldn't do anyway”, 1-4 representing degree of breathlessness and 5 representing the greatest difficulty with performing ADL (someone else completes)
  • Responses to items 1-15 are added; the total score can range from 0 to 75 points, with higher scores indicating greater functional limitation
  • The score 0 can reduce the total LCADL raw score and overestimate functional status, so a LCADL % total score may be used
  • Item 16 refers to the client’s overall perception of how breathing impacts ADL performance which needs to be answered “A lot,” “A little,” or “Not at all.”

  • The cut-off point of 37% was identified in Sample 1 (AUC = 0.70, sensitivity = 0.56 and specificity = 0.74)

  • The cut-off point of 28% (LCADL %total score) had 83% sensitivity and 72% specificity (UAC = 0.80) to discriminate patients’ functional status according to anchor-based approach

Criterion Validity (Predictive/Concurrent)

Severe COPD: (Garrod et al., 2000)

  • Excellent concurrent validity with St. George’s Respiratory Questionnaire (SGRQ) activity score (p = 0.70; P < 0.0001)
  • Adequate concurrent validity with SGRQ total score (p = .42; P = 0.001) and impact component (p = 0.48; P = 0.004)
  • Poor concurrent validity with SGRQ symptoms (p = 0.24; P = 0.007)
  • Adequate concurrent validity between Nottingham Extended Activity of Daily Living Questionnaire (EADL) score (p = -0.46; P = 0.0008)
  • Poor concurrent validity with Hospital Anxiety and Depression Score (HAD)  depression score (p = -0.25; P =0.06)
  • Poor concurrent validity with HAD anxiety score (p = 0.28; P = 0.03)
  • Adequate concurrent validity with Forced Vital Capacity (FVC) (p = - 0.38; P = 0.007)
  • Poor concurrent validity with Forced Expiratory Volume in one second (FEV1) (p = - 0.18; P = 0.18)

  • Adequate concurrent validity between change in LADL score and  change in Chronic Respiratory Disease Questionnaire (CRDQ) score (p = -0.37; P = 0.004)

Construct Validity

Severe COPD: (Garrod et al., 2000; n = 60)

  • The LCADL total mean (SD) score [37.0 (12.7)] was over twice as high as score in 20 patients with no history of respiratory disease[17.5 (3.51)]

 

Patients waiting for a lung transplantation: (Muller et at., 2013)

  • Significant association of total score (%) with the six-minute walk distance:  B = -0.079, p = 0.002
  • Significant association of total score (%) with the six-minute walk work: B = -0.348, p = 0.002

 

Refractory breathlessness due to advanced respiratory disease: (Reilly et at., 2016)

  • Moderate convergent validity between the LCADL Total score and subcategories of Chronic Respiratory Questionnaire (CRQ): r = - 0.40 (Health-related quality of life), r = - 0.56 (Dyspnea), r = - 0.31 (fatigue)
  • Moderate convergent validity between the LCADL Total score and Palliative care Outcome Scale - symptoms (POS-s): r = 0.40
  • Weak convergent validity between the LCADL Total score and Numerical Rating Scale (NRS): r = 0.24 - 0.25 and CRQ Mastery
  • Weak convergent validity between the LCADL Total score and CRQ mastery: r = - 0.30
  • Weak convergent validity between the LCADL Total score and Hospital Anxiety and Depression (HAD): r = - 0.29 (depression) and r = 0.08 (anxiety)
  • Divergent validity in between the LCADL Total score and pulmonary function measures with r < 0.2

Content Validity

Items of LCADL were generated through interviews with patients with moderate to severe COPD and patients with very severe COPD. It was further developed by item reduction process considering appropriateness of the activity (i.e. ‘wouldn't do anyway or do not get breathless’), demographic variables (i.e. gender and age), association with general health, and poor test-retest reliability. Domains developed through a principal component analysis. (Garrod et al., 2000).

Moderate to severe COPD: (Belo et al., 2019)

  • Gender potentially causes bias to the assessment of functional status by the LCADL, especially in the domestic domain, with overestimation of men’s status compared to women
  • Sample 1 (n = 138)
    • Median (IQR) for LCADL domestic for men = 4 (2-7)
    • Median (IQR) for LCADL domestic for women = 10 (7-15)
  • Sample 2 (n = 70)
    • Median (range) for LCADL domestic ≥ 37% cutoff point, men = 7 (2-11)
    • Median (range) for LCADL domestic ≥ 37% cutoff point, women = 16 (12-19)

Floor/Ceiling Effects

Patients waiting for a lung transplantation: (Muller et at., 2013)

  • No floor or ceiling effect

 

Refractory breathlessness due to advanced respiratory disease: (Reilly et at., 2016)

  • No floor or ceiling effect for the LCADL total score. The LCADL domestic domain demonstrated a ceiling effect, with 23% of respondents achieving the highest possible score.

Responsiveness

Severe COPD: (Garrod et al., 2002; n = 59)

  • Mean difference pre- & post-pulmonary rehabilitation (6 weeks minimum) in LCADL total = - 5.91 
  • All domains except the domestic component had a statistically significant reduction in dyspnea after pulmonary rehabilitation.

 

Severe COPD: (Kovelis et al., 2011)

  • Significant improvements in LCADL total score and self-care, domestic, and leisure domains after a 12-week training program. The overall effect size around or above 0.50 suggests a moderate change.
