The National Disability Insurance Scheme (NDIS) in Australia and other similar international movements towards consumer direction have highlighted the importance of including consumers to ensure their service preferences are operationalised. Discrete Choice Experiments (DCEs) are an established method to quantify consumer preferences. The feasibility of using DCEs with people with intellectual disability is largely untested. Consenting participants eligible for disability support services (n = 18) participated in the mixed methods exploratory study. The DCE comprised a series of choices between two hypothetical service providers offering a combination of services relating to social and economic participation (e.g. support with finding and keeping a job), with four levels of service (no service, online support, group support, one to one support). Pictographs and simplified English were used to represent the hypothetical services and levels and a ‘think aloud’ protocol adopted. Most participants (N = 16, 89%) completed the DCE task. The findings from the think aloud task indicated that some participants were weighing up the options and making decisions based on their goals and personal preferences. However, other participants did not focus on all presented attributes and levels when making a decision; a common ‘short-cut’ heuristic also observed in DCE tasks with general population participants. Further research including investigating other DCE techniques, such as best-worst scaling, would be beneficial to identify how preference-elicitation tasks can be developed and applied with people with intellectual disabilities to ensure that future service innovations are designed and administered in ways which best meet their needs and preferences.

使用离散选择实验来引出轻度智障人士的服务偏好:一项探索性研究

澳大利亚的国家残疾保险计划 (NDIS) 和其他类似的面向消费者方向的国际运动都强调了包括消费者在内的重要性,以确保他们的服务偏好得到实施。离散选择实验 (DCE) 是一种量化消费者偏好的既定方法。对智障人士使用 DCE 的可行性在很大程度上未经测试。有资格获得残疾支持服务的同意参与者(n = 18) 参加了混合方法探索性研究。DCE 包括两个假设的服务提供商之间的一系列选择,提供与社会和经济参与相关的服务组合(例如,支持寻找和保持工作),具有四个服务级别(无服务、在线支持、团体支持、一个一个支持)。象形文字和简体英文被用来表示假设的服务和水平,并采用了“大声思考”协议。大多数参与者(N = 16, 89%) 完成了 DCE 任务。大声思考任务的结果表明,一些参与者正在权衡选项并根据他们的目标和个人喜好做出决定。然而,其他参与者在做出决定时并未关注所有呈现的属性和级别;在一般人群参与者的 DCE 任务中也观察到了一种常见的“捷径”启发式方法。进一步的研究,包括调查其他 DCE 技术,例如最佳最差缩放,将有助于确定如何开发偏好激发任务并将其应用于智障人士,以确保未来服务创新的设计和管理方式最符合他们的需求和偏好。
