Abstract This study was conducted to develop a service evaluation index for Internet addiction through expert consensus using the Delphi method in South Korea. The study contained three rounds: we drafted the index in the first round by reviewing the existing literature and seeking expert advice, and in rounds two and three, we consulted 12 experts via an online survey to gather their opinions on the appropriateness, clarity, and applicability of the drafted index. In rounds two and three, we collected more-detailed opinions based on the results of earlier rounds. Content validity was high, and it increased during the later rounds of the Delphi study. The Internet addiction service evaluation index that resulted comprised four categories: prevention, treatment, aftercare, and service outcomes. The prevention section contains 17 sub-indices, including preventive education, a screening test and intensive prevention programs, and service promotion. The treatment section contains 15 sub-indices that evaluate diagnosis, planning, and treatment services. The aftercare section uses two sub-indices to assess whether a systematic aftercare is provided. The service outcome section includes 19 sub-indices that evaluate service effectiveness, diagnosis of comorbid conditions, and risk factors. This index could effectively standardize services, facilitate operations, and promote objective evaluation within related service delivery systems.

通过Delphi方法开发网络成瘾服务评估指标

摘要进行了本研究，目的是通过韩国的Delphi方法，通过专家共识建立网络成瘾的服务评估指标。该研究分为三轮：第一轮通过回顾现有文献并寻求专家意见起草了该指数；在第二轮和第三轮中，我们通过在线调查咨询了12位专家，以收集他们对于适当性，明确性和有效性的意见。起草索引的适用性。在第二轮和第三轮中，我们根据前几轮的结果收集了更详细的意见。内容有效性很高，并且在后来的Delphi研究中有所提高。互联网成瘾服务评估指数包括四类：预防，治疗，善后和服务结果。预防部分包含17个子索引，包括预防教育，筛查测试和强化预防计划以及服务推广。治疗部分包含15个评估诊断，计划和治疗服务的子指数。善后服务部分使用两个子索引来评估是否提供了系统的善后服务。服务结果部分包括19个子索引，这些索引评估服务有效性，合并症诊断和风险因素。该指数可以有效地标准化服务，促进运营并促进相关服务交付系统内的客观评估。后续处理部分使用两个子索引来评估是否提供了系统的后续处理。服务结果部分包括19个子索引，这些索引评估服务有效性，合并症诊断和风险因素。该索引可以有效地标准化服务，促进运营并促进相关服务交付系统内的客观评估。善后服务部分使用两个子索引来评估是否提供了系统的善后服务。服务结果部分包括19个子索引，这些索引评估服务有效性，合并症诊断和风险因素。该索引可以有效地标准化服务，促进运营并促进相关服务交付系统内的客观评估。
