Therapist-guided internet-based cognitive behaviour therapy (ICBT) has been proposed as a potential means to increase individuals' access to quality mental health care and effective treatment. Guided ICBT aims to increase a patient's knowledge and competence to better cope with their disorder. Despite the growing evidence supporting the effects of guided ICBT, there is remarkably little research on the different factors that are important for patients to achieve effects from using such digital treatment interventions. Thus, the aim of this study was to conduct a user evaluation of a therapist-guided ICBT program using the updated DeLone and McLean (D&M) model for measuring information systems (IS) success or effectiveness. This model includes the following six dimensions: system quality, information quality, service quality, intention to use and use, user satisfaction, and net benefits (impacts or effect).

Ten users of a Norwegian therapist-guided ICBT program for treating anxiety disorders named ‘Assisted Self-Help’ (Assistert Selvhjelp) participated in phone-based individual interviews. Data were analysed using directed content analysis. Results showed that the participants were quite satisfied with the program's system quality and information quality. However, participants suggested improvements, including in-program instruction, improved visibility of system status, more flexibility regarding automated measurement surveys, and the inclusion of more videos with patient stories. Further, the results indicated a need for improvement in the service quality of guided ICBT introduction, instruction, follow-up, guidance, and support from therapists. The results showed that user friendliness and high educational content might not be sufficient for a therapist-guided ICBT program to be perceived as effective. It might also be necessary for therapists to provide follow-up, guidance, and support that are more in line with individual patient needs. Thus, the results suggest that guided ICBT requires active participation from all involved in the process, including the therapist.

已经提出了以治疗师为指导的基于互联网的认知行为疗法（ICBT），作为增加个人获得优质心理保健和有效治疗机会的潜在手段。指导性ICBT旨在增加患者的知识和能力，以更好地应对他们的疾病。尽管有越来越多的证据支持指导性ICBT的疗效，但对于对患者而言重要的不同因素方面的研究极少，而这些因素对于通过使用此类数字治疗干预来获得疗效至关重要。因此，本研究的目的是使用更新的DeLone和McLean（D＆M）模型对治疗师指导的ICBT程序进行用户评估，以评估信息系统（IS）的成功或有效性。该模型包括以下六个维度：系统质量，信息质量，服务质量，

挪威治疗师引导ICBT计划的十个用户用于治疗命名为“焦虑症辅助自-帮助”（Assistert Selvhjelp）参加了基于电话的个人访谈。使用定向内容分析对数据进行分析。结果表明，参与者对该程序的系统质量和信息质量非常满意。但是，参与者建议进行改进，包括程序内指令，改进的系统状态可见性，自动测量调查的更大灵活性以及包含更多带有患者故事的视频。此外，结果表明，有必要提高ICBT指南的引入，指导，随访，指导和治疗师支持的服务质量。结果表明，用户友好性和较高的教育程度可能不足以使以治疗师为指导的ICBT计划被视为有效。治疗师也可能有必要提供更符合个别患者需求的随访，指导和支持。因此，结果表明，指导性的ICBT要求过程中的所有参与者（包括治疗师）积极参与。
