Computerized cognitive training (CCT) interventions may have an important role in improving cognition among patients with heart failure. Ensuring treatment fidelity of CCT interventions is an essential part of testing their efficacy.
The aim of this study was to describe facilitators of and barriers to treatment fidelity perceived by CCT intervenors while delivering the interventions to patients with heart failure.
A qualitative descriptive study was completed with 7 intervenors who delivered CCT interventions in 3 studies. Directed content analysis revealed 4 main themes of perceived facilitators: (1) training for intervention delivery, (2) supportive work environment, (3) prespecified implementation guide, and (4) confidence and awareness. Three main themes were identified as perceived barriers: (1) technical issues, (2) logistic barriers, and (3) sample characteristics.
This study is novel because it was one of the few studies focused on the intervenors' perceptions rather than the patients' perception of using CCT interventions. Beyond the treatment fidelity recommendations, this study found new components that might help the future investigators in designing and implementing CCT interventions with high treatment fidelity.
计算机化认知训练（CCT）干预措施可能在改善心力衰竭患者的认知方面发挥重要作用。确保 CCT 干预措施的治疗一致性是检验其疗效的重要组成部分。
本研究旨在描述 CCT 干预者在向心力衰竭患者提供干预措施时，对治疗一致性的感知促进因素和障碍因素。
对 7 名在 3 项研究中提供 CCT 干预措施的干预者进行了定性描述性研究。定向内容分析揭示了感知促进因素的 4 个主要主题：（1）干预措施传递培训，（2）支持性工作环境，（3）预设实施指南，以及（4）信心和意识。确定了 3 个主要的感知障碍主题：（1）技术问题，（2）后勤障碍，以及（3）样本特征。
这项研究是新颖的，因为它是少数关注干预者对使用 CCT 干预措施的看法的研究之一，而不是关注患者的看法。除了治疗一致性建议外，这项研究还发现了一些新的组成部分，这可能有助于未来的研究人员在设计和实施具有高度治疗一致性的 CCT 干预措施方面。
