[Evaluation of the questionnaire for subhealth status survey based on the symptoms in traditional Chinese medicine].
OBJECTIVE
To evaluate the reliability and validity of the questionnaire we designed for subhealth status survey based on the symptoms described in traditional Chinese medicine.


METHODS
By on-the-spot investigation, the recovery rate of the questionnaires was 96.3% and the response rate of the items was 97.2%.


RESULTS
Internal consistency reliability coefficient of the questionnaire was high (0.9274-0.9676), and each item was closely associated with its related factors (with Spearman coefficient mostly above 0.6 except for that for bodily symptoms in female). Factor loading was approximately consistent with the structure and content of the questionnaire.


CONCLUSIONS
This subhealth status questionnaire can be reliable and effective.
