Building a system dynamics model based on ethnographic case study has the advantage of using empirically documented contextual factors and processes of change in a real-world and real-time setting that can then be tested in the same and other settings. System dynamics modeling offers great promise for addressing persistent problems like HIV and other sexually transmitted epidemics, particularly in complex rapidly developing countries such as China. We generated a system dynamics model of a multilevel intervention we conducted to promote female condoms for HIV\/sexually transmitted infection (STI) prevention among Chinese women in sex work establishments. The model reflects factors and forces affecting the study\u2019s intervention, implementation, and effects. To build this conceptual model, we drew on our experiences and findings from this intensive, longitudinal mixed-ethnographic and quantitative four-town comparative case study (2007-2012) of the sex work establishments, the intervention conducted in them, and factors likely to explain variation in process and outcomes in the four towns. Multiple feedback loops in the sex work establishments, women\u2019s social networks, and the health organization responsible for implementing HIV\/STI interventions in each town and at the town level directly or indirectly influenced the female condom intervention. We present the conceptual system dynamics model and discuss how further testing in this and other settings can inform future community interventions to reduce HIV and STIs.<\/jats:p>","DOI":"10.1177\/1090198113490723","type":"journal-article","created":{"date-parts":[[2013,10,1]],"date-time":"2013-10-01T06:02:34Z","timestamp":1380607354000},"page":"111S-122S","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":13,"title":["Multilevel Dynamic Systems Affecting Introduction of HIV\/STI Prevention Innovations Among Chinese Women in Sex Work Establishments"],"prefix":"10.1177","volume":"40","author":[{"given":"Margaret R.","family":"Weeks","sequence":"first","affiliation":[{"name":"Institute for Community Research, Hartford, CT, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianghong","family":"Li","sequence":"additional","affiliation":[{"name":"Institute for Community Research, Hartford, CT, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Susu","family":"Liao","sequence":"additional","affiliation":[{"name":"Peking Union Medical College and Chinese Academy of Medical Sciences, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qingning","family":"Zhang","sequence":"additional","affiliation":[{"name":"Peking Union Medical College and Chinese Academy of Medical Sciences, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jennifer","family":"Dunn","sequence":"additional","affiliation":[{"name":"Institute for Community Research, Hartford, CT, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yanhong","family":"Wang","sequence":"additional","affiliation":[{"name":"Peking Union Medical College and Chinese Academy of Medical Sciences, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jingmei","family":"Jiang","sequence":"additional","affiliation":[{"name":"Peking Union Medical College and Chinese Academy of Medical Sciences, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2013,10,1]]},"reference":[{"key":"bibr1-1090198113490723","doi-asserted-by":"publisher","DOI":"10.1016\/j.socscimed.2006.03.026"},{"key":"bibr2-1090198113490723","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2458-10-759"},{"key":"bibr3-1090198113490723","volume-title":"Update on the HIV\/STD epidemic and response in China, 2005","author":"Chinese Ministry of Health UNAIDS and WHO","year":"2006"},{"key":"bibr4-1090198113490723","doi-asserted-by":"publisher","DOI":"10.1097\/00007435-200301000-00018"},{"key":"bibr5-1090198113490723","first-page":"314","volume":"38","author":"Ding Y.","year":"2005","journal-title":"Journal of Acquired Immune Deficiency Syndromes"},{"key":"bibr6-1090198113490723","doi-asserted-by":"publisher","DOI":"10.1080\/13691050701561393"},{"key":"bibr7-1090198113490723","doi-asserted-by":"publisher","DOI":"10.1093\/oxfordjournals.aje.a117678"},{"key":"bibr8-1090198113490723","doi-asserted-by":"publisher","DOI":"10.1007\/s10464-007-9104-5"},{"key":"bibr9-1090198113490723","doi-asserted-by":"publisher","DOI":"10.1007\/s10464-007-9109-0"},{"key":"bibr10-1090198113490723","doi-asserted-by":"publisher","DOI":"10.1007\/s10464-009-9229-9"},{"key":"bibr11-1090198113490723","doi-asserted-by":"publisher","DOI":"10.2105\/AJPH.2009.159434"},{"key":"bibr12-1090198113490723","doi-asserted-by":"publisher","DOI":"10.1007\/s10464-007-9114-3"},{"issue":"1","key":"bibr13-1090198113490723","first-page":"A18","volume":"7","author":"Homer J.","year":"2010","journal-title":"Preventing Chronic Disease"},{"key":"bibr14-1090198113490723","doi-asserted-by":"publisher","DOI":"10.1002\/sres.2105"},{"key":"bibr15-1090198113490723","doi-asserted-by":"publisher","DOI":"10.1080\/13691050410001701948"},{"key":"bibr16-1090198113490723","doi-asserted-by":"publisher","DOI":"10.1007\/s10461-010-9804-y"},{"key":"bibr17-1090198113490723","doi-asserted-by":"publisher","DOI":"10.1007\/s10461-006-9143-1"},{"key":"bibr18-1090198113490723","first-page":"196","volume-title":"Sexuality research in China","volume":"30","author":"Liao S.
