Objective: To develop a HIV infection risk assessment tool for men who have sex with men (MSM) based on Delphi method. Methods: After an exhaustive literature review, we used Delphi method to determine the specific items and relative risk scores of the assessment tool through two rounds of specialist consultation and overall consideration of the opinions and suggestions of 17 specialists. Results: The positivity coefficient through first and second round specialist consultation was 100.0% and 94.1%, respectively. The mean of authority coefficients (Cr) was 0.86. Kendall's W coefficient of the specialist consultation was 0.55 for the first round consultation (χ(2)=84.426, P<0.001) and 0.46 for the second round consultation (χ(2)=65.734, P<0.001), respectively, suggesting that the specialists had similar opinions. The final HIV infection risk assessment tool for MSM has 8 items. Conclusions: The HIV infection risk assessment tool for MSM, developed under the Delphi method, can be used in the evaluation of HIV infection risk in MSM and individualized prevention and intervention. However, the reliability and validity of this risk assessment tool need to be further evaluated.
目的： 构建MSM个体HIV感染风险评估工具。 方法： 在查阅文献的基础上，应用德尔菲法经过2轮专家咨询调查，综合考虑17位专家的意见与建议，确定评估工具指标及参考风险分值。 结果： 2轮专家咨询调查积极系数分别为100.0%和94.1%；专家权威程度（Cr）均值为0.86；肯德尔和谐系数（Kendall’s W）分别为0.55（χ(2)=84.426，P<0.001）、0.46（χ(2)=65.734，P<0.001），表明专家意见趋于一致，研究结果可靠性高。最终确定终稿"MSM个体HIV感染风险评估工具"包括8个指标。 结论： 应用德尔菲法建立的"MSM个体HIV感染风险评估工具"可用于评估MSM人群HIV感染风险，进而开展个性化预防干预，但还有待进一步信度、效度评价。.
