Background Cardiac rehabilitation (CR) is a programme of care offered to people who recently experienced a cardiac event. There is a growing focus on home-based formats of CR and a lack of evidence on preferences for psychological care in CR. This pilot study aimed to investigate preferences for delivery attributes of a psychological therapy intervention in CR patients with symptoms of anxiety and/or depression. Methods A discrete choice experiment (DCE) was conducted and recruited participants from a feasibility trial. Participants were asked to choose between two hypothetical interventions, described using five attributes; intervention type (home or centre-based), information provided, therapy manual format, cost to the National Health Service (NHS) and waiting time. A separate opt-out was included. A conditional logit using maximum likelihood estimation was used to analyse preferences. The NHS cost was used to estimate willingness to pay for aspects of the intervention delivery. Results 35 responses were received (39% response rate). Results indicated that participants would prefer to receive any form of therapy compared with no therapy. Statistically significant results were limited, but included participants being keen to avoid not receiving information prior to therapy (β=−0.270; p=0.03) and preferring a lower cost to the NHS (β=−0.001; p=0.00). No significant results were identified for the type of psychological intervention, format of therapy/exercises and programme start time. Coefficients indicated preferences were stronger for home-based therapy compared with centre-based, but this was not significant. Conclusions The pilot study demonstrates the feasibility of a DCE in this group, it identifies potential attributes and levels, and estimates the sample sizes needed for a full study. Preliminary evidence indicated that sampled participants tended to prefer home-based psychological therapy in CR and wanted to receive information before initiating therapy. Results are limited due to the pilot design and further research is needed. Anonymised data are available on reasonable request from the corresponding author.

心脏康复心理干预的交付偏好：试点离散选择实验

背景 心脏康复 (CR) 是一项为最近经历过心脏事件的人提供的护理计划。人们越来越关注以家庭为基础的 CR 形式，但缺乏关于 CR 中心理护理偏好的证据。该试点研究旨在调查对具有焦虑和/或抑郁症状的 CR 患者进行心理治疗干预的传递属性的偏好。方法 进行离散选择实验 (DCE) 并从可行性试验中招募参与者。参与者被要求在使用五个属性描述的两种假设干预之间进行选择；干预类型（基于家庭或中心）、提供的信息、治疗手册格式、国民健康服务 (NHS) 的费用和等待时间。包括一个单独的选择退出。使用最大似然估计的条件 logit 用于分析偏好。NHS 成本用于估计为干预提供方面的支付意愿。结果 收到 35 份回复（39% 的回复率）。结果表明，与不接受治疗相比，参与者更愿意接受任何形式的治疗。统计上显着的结果是有限的，但包括热衷于避免在治疗前不接收信息的参与者（β=-0.270；p=0.03）和更喜欢较低的费用而不是 NHS（β=-0.001；p=0.00）。在心理干预的类型、治疗/锻炼的形式和计划开始时间方面没有发现显着的结果。系数表明，与以中心为基础的治疗相比，对家庭治疗的偏好更强，但这并不显着。结论 试点研究证明了 DCE 在该组中的可行性，它确定了潜在的属性和水平，并估计了完整研究所需的样本量。初步证据表明，抽样参与者倾向于在 CR 中进行基于家庭的心理治疗，并希望在开始治疗之前接收信息。由于试点设计，结果有限，需要进一步研究。可应通讯作者的合理要求提供匿名数据。由于试点设计，结果有限，需要进一步研究。可应通讯作者的合理要求提供匿名数据。由于试点设计，结果有限，需要进一步研究。可应通讯作者的合理要求提供匿名数据。
