This study examines (1) coalition survival, (2) prevalence of evidence-based prevention interventions (EBPIs) to reduce substance abuse implemented as part of the Tennessee Strategic Prevention Framework (SPF) State Incentive Grant (SIG), (3) EBPI sustainability, and (4) factors that predict EBPI sustainability. Secondary data were collected on 27 SPF SIG-funded coalitions and 88 EBPI and non-EBPI implementations. Primary data were collected by a telephone interview/web survey five and one-half years after the SPF SIG ended. Results from secondary data show that 25 of the 27 coalitions survived beyond the SPF SIG for one to five and one-half years; 19 coalitions (70%) were still active five and one-half years later. Further, 88 EBPIs and non-EBPIs were implemented by 27 county SPF SIG coalitions. Twenty-one (21) of 27 coalitions (78%) implemented one to three EBPIs, totaling 37 EBPI implementations. Based on primary survey data on 29 of the 37 EBPI implementations, 28 EBPIs (97%) were sustained between two and five and one-half years while 22 EBPI implementations (76%) were sustained for five and one-half years. When controlling for variability among coalitions (nesting of EBPIs in coalitions), increases in data resources (availability of five types of prevention data) was a strong predictor of length of EBPI sustainability. Positive change in extramural funding resources and level of expertise during SPF SIG implementation, as well as level of coalition formalization at the end of the SPF SIG predicted EBPI sustainability length. One intervention attribute (trialability) also predicted length of sustainability. Implications are discussed.
（1）联盟的存续情况；（2）作为田纳西州战略预防框架（SPF）州激励拨款（SIG）一部分实施的减少药物滥用的循证预防干预措施（EBPI）的普及情况；（3）EBPI的可持续性；以及（4）预测EBPI可持续性的因素。收集了27个由SPF SIG资助的联盟以及88个EBPI和非EBPI实施项目的二手数据。在SPF SIG结束五年半后，通过电话访谈/网络调查收集了一手数据。二手数据结果显示，27个联盟中有25个在SPF SIG结束后存续了一至五年半；五年半后，19个联盟（70%）仍在活跃。此外，27个县的SPF SIG联盟实施了88项EBPI和非EBPI项目。27个联盟中有21个（78%）实施了一至三项EBPI，共计37项EBPI实施项目。基于对37项EBPI实施项目中的29项的初步调查数据，28项EBPI（97%）在两至五年半期间得以持续，而22项EBPI实施项目（76%）持续了五年半。在控制联盟间的变异性（EBPI在联盟中的嵌套情况）后，数据资源的增加（五类预防数据的可获取性）是EBPI可持续时长的有力预测指标。SPF SIG实施期间外部资金资源的积极变化、专业水平，以及SPF SIG结束时联盟的正规化程度预测了EBPI的可持续时长。一项干预属性（可试验性）也预测了可持续时长。文中讨论了相关影响。
