Psychosocial interventions for patients with chronic hepatitis C viral (HCV) infection are needed to attenuate the impact of extrahepatic symptoms, comorbid conditions, and treatment side effects on HCV health outcomes. We adapted empirically-supported interventions for similar patient populations to develop a Cognitive Behavioral Coping Skills group intervention for HCV patients (CBCS-HCV) undergoing treatment. The objectives of this paper are to describe the research activities associated with CBCS-HCV development and pilot testing, including: (1) formative work leading to intervention development; (2) preliminary study protocol; and (3) pilot feasibility testing of the intervention and study design. Formative work included a literature review, qualitative interviews, and adaption, development, and review of study materials. A preliminary study protocol is described. We evaluate the feasibility of conducting a randomized controlled trial (RCT) of the CBCS-HCV with 12 study participants in Wave 1 testing to examine: (a) feasibility of intervention delivery; (b) patient acceptability; (c) recruitment, enrollment, retention; (d) feasibility of conducting a RCT; (d) therapist protocol fidelity; and (e) feasibility of data collection. Numerous lessons were learned. We found very high rates of data collection, participant attendance, engagement, retention and acceptability, and therapist protocol fidelity. We conclude that many aspects of the CBCS-HCV intervention and study protocol were highly feasible. The greatest challenge during this Wave 1 pilot study was efficiency of participant enrollment due to changes in standard of care treatment. These findings informed two additional waves of pilot testing to examine effect sizes and potential improvements in clinical outcomes, with results forthcoming.
慢性丙型肝炎病毒(HCV)感染患者需要心理社会干预措施,以减轻肝外症状、合并症和治疗副作用对HCV健康结局的影响。我们对针对类似患者群体的经验证有效的干预措施进行了调整,为正在接受治疗的HCV患者开发了一种认知行为应对技能小组干预措施(CBCS-HCV)。本文的目的是描述与CBCS-HCV开发和试点测试相关的研究活动,包括:(1)导致干预措施开发的形成性工作;(2)初步研究方案;以及(3)干预措施和研究设计的试点可行性测试。形成性工作包括文献综述、定性访谈以及研究材料的改编、开发和审查。描述了一项初步研究方案。我们评估了在第1波测试中对12名研究参与者进行CBCS-HCV随机对照试验(RCT)的可行性,以检验:(a)干预措施实施的可行性;(b)患者的可接受性;(c)招募、入组、保留率;(d)进行RCT的可行性;(d)治疗师对方案的忠诚度;以及(e)数据收集的可行性。我们吸取了许多经验教训。我们发现数据收集率、参与者出勤率、参与度、保留率和可接受性以及治疗师对方案的忠诚度都非常高。我们得出结论,CBCS-HCV干预措施和研究方案的许多方面都具有高度可行性。在第1波试点研究期间,最大的挑战是由于护理标准治疗的变化导致参与者入组效率低下。这些发现为另外两波试点测试提供了信息,以检验效应大小和临床结局的潜在改善情况,结果即将公布。
