Key result

The Brazilian Portuguese version of the Duke Activity Status Index demonstrated significant positive correlation with VO2max (r = 0.51, p < 0.001) in patients with cardiovascular disease.

Why the study?

Is the Brazilian Portuguese version of the DASI a valid and reliable tool to assess functional capacity in patients with cardiovascular disease?

Population

97 adults with cardiovascular disease and physician referral to exercise testing, BMI 18.6-39.9 kg/m2, from…

Design

Structured PICO

Is the Brazilian Portuguese version of the DASI a valid and reliable tool to assess functional capacity in patients with cardiovascular disease?

P
Population
97 Brazilian adults over 22 years of age with cardiovascular disease referred for exercise testing.
E
Exposure
Brazilian Portuguese translation of the Duke Activity Status Index (DASI) questionnaire
O
Outcome
Psychometric properties including test-retest reliability, inter-rater reliability, internal consistency, concurrent validity with VO2max, and construct validitypatient reported

Main Result

Effect estimate: r = 0.51

p-value: p=<0.001

Limitations

  • Did not use an individualized ramp treadmill protocol or directly measure oxygen uptake.
  • Lower educational level of the subjects could have increased interpretation difficulties.
  • Some questions are related to unspecific activities that could have variations in terms of METs (e.g., sexual relations).

Cite This Study

Coutinho-Myrrha et al. (2014) conducted a cross-sectional in Cardiovascular disease (n=97). Duke Activity Status Index (DASI) - Brazilian Portuguese version vs. Maximal exercise testing (VO2max) was evaluated on Concurrent criterion validity (correlation between DASI score and VO2max) (r = 0.51, p=<0.001). The Brazilian Portuguese version of the Duke Activity Status Index demonstrated significant positive correlation with VO2max (r = 0.51, p < 0.001) in patients with cardiovascular disease.
