英文摘要	Background: suboptimal health status (shs) is characterized by ambiguous health complaints, general weakness, and lack of vitality, and has become a new public health challenge in china. it is believed to be a subclinical, reversible stage of chronic disease. studies of intervention and prognosis for shs are expected to become increasingly important. consequently, a reliable and valid instrument to assess shs is essential. we developed and evaluated a questionnaire for measuring shs in urban chinese. methods: focus group discussions and a literature review provided the basis for the development of the questionnaire. questionnaire validity and reliability were evaluated in a small pilot study and in a larger cross-sectional study of 3000 individuals. analyses included tests for reliability and internal consistency, exploratory and confirmatory factor analysis, and tests for discriminative ability and convergent validity. results: the final questionnaire included 25 items on shs (shsq-25), and encompassed 5 subscales: fatigue, the cardiovascular system, the digestive tract, the immune system, and mental status. overall, 2799 of 3000 participants completed the questionnaire (93.3%). test-retest reliability coefficients of individual items ranged from 0.89 to 0.98. item-subscale correlations ranged from 0.51 to 0.72, and cronbach's alpha was 0.70 or higher for all subscales. factor analysis established 5 distinct domains, as conceptualized in our model. one-way anova showed statistically significant differences in scale scores between 3 occupation groups; these included total scores and subscores (p < 0.01). the correlation between the shs scores and experienced stress was statistically significant (r = 0.57, p < 0.001). conclusions: the shsq-25 is a reliable and valid instrument for measuring sub-health status in urban chinese.
