ObjectiveTo investigate the condom use of men who have sex with men （MSM） in Shanghai， the information motivation behavioral skills model （IMB） theory was used to introduce psychosocial factors and study the relevant factors of consistent condom use （CCU） in this population. MethodsA cross-sectional study of 547 MSM in four districts of Shanghai was conducted by snowball sampling. The structural equation model based on psychosocial optimization was constructed and validated using the data collected by structured questionnaires. ResultsAmong the 547 respondents， the proportion of CCU in the past six months was 45.5%. Comparing the fitness of the initial model with that of the adjusted model， we found that the fitness of the adjusted model was good. ConclusionThe proportion of CCU among MSM in Shanghai is relatively low； In addition， information and motivation do not directly affect the CCU of this population； Only behavioral skills have a direct effect on CCU. Finally， social psychological measures should be emphasized for this population， and comprehensive and multi-level strategies should be formulated to control the spread of HIV in this population.
