The minimum clinically important difference in three different versions of the Constitution in Chinese Medicine Questionnaire
We aimed to determine the minimum clinically important difference (MCID) of three different item versions of the Constitution in Chinese Medicine Questionnaire (CCMQ)
to facilitate the clinical application of CCMQ.
Methods
2
In total
537 subjects were included in the analysis. All subjects voluntarily completed a comprehensive of traditional Chinese medicine (TCM) constitution intervention (mood
diet
daily living
exercise
and acupoints). The subjects filled out the 60-item CCMQ and the Short Form Health Questionnaire (SF-36) at baseline and 3 months after the intervention. The result of the 41-item and the 30-item CCMQ were scored according to the result of the 60-item CCMQ. An anchor-based approach and a distribution-based approach were used to estimate the MCID of the three versions of the CCMQ. The anchor of the anchor-based approach was SF-36 item 1
and the analysis method were the mean change method and multiple linear regression. The standardized response mean (SRM) was used for the distribution-based approach.
Results
2
The mean change method and multiple linear regression estimation result were averaged and rounded to whole numbers. The MCID values of the 60-item CCMQ of balanced type
qi-deficiency type
yang-deficiency type
yin-deficiency type
phlegm-dampness type
dampness-heat type
blood-stasis type
qi-depression type
and special diathesis type were 5
-5
-3
-3
-4
-4
-4
-4
and -2
respectively. The MCID values of the 41-item CCMQ were 4
-6
-4
-2
-4
-4
-4
-4
and -2
respectively. The MCID values of the 30-item CCMQ were 5
-5
-4
-3
-4
-5
-4
-5
and -2
respectively. The MCID values estimated by the anchor-based approach were higher than those estimated when SRM was 0.2
except for the special diathesis type.
Conclusion
2
The MCID values of three different versions of the CCMQ estimated in this study can reflect the minimum score change of the CCMQ considered important and meaningful by patients
which is helpful for doctors in explaining the effect of TCM constitution intervention or setting intervention targets.
