Theories of behaviour change and health behaviour change interventions are most often evaluated in between-person designs. However, behaviour change theories apply to individuals not groups and behavioural interventions ultimately aim to achieve within-person rather than between-group change. Within-person methodology, such as N-of-1 (also known as single case design), can circumvent this issue, though has multiple design-specific challenges. This paper provides a conceptual review of the challenges and potential solutions for undertaking N-of-1 studies in health psychology. Key challenges identified include participant adherence to within-person protocols, carry-over and slow onset effects, suitability of behaviour change techniques for evaluation in N-of-1 experimental studies, optimal allocation sequencing and blinding, calculating power/sample size, and choosing the most suitable analysis approach. Key solutions include involving users in study design, employing recent technologies for unobtrusive data collection and problem solving by design. Within-person designs share common methodological requirements with conventional between-person designs but require specific methodological considerations. N-of-1 evaluation designs are appropriate for many though not all types of interventions. A greater understanding of patterns of behaviours and factors influencing behaviour change at the within-person level is required to progress health psychology into a precision science.

健康心理学中N-1分设计研究的挑战和解决方案。

行为改变和健康行为改变干预的理论最常在人际关系设计中进行评估。然而,行为改变理论不适用于个人而不是群体,行为干预最终旨在实现人际而非群体之间的改变。面对面的方法论,例如N-of-1(也称为单一案例设计),尽管有多个针对特定设计的挑战,但却可以规避此问题。本文从概念上回顾了进行健康心理学N-1的挑战和可能的解决方案。确定的主要挑战包括参与者遵守人际协议,遗留和起效缓慢,行为改变技术是否适用于N-1的实验研究,最佳分配顺序和盲法,计算功效/样本量,并选择最合适的分析方法。关键解决方案包括使用户参与研究设计,采用最新技术进行不干扰数据的收集以及通过设计解决问题。个人内部设计与常规的个人间设计具有共同的方法要求,但需要特定的方法考虑。N比1评估设计适用于许多(但不是全部)干预措施。为了使健康心理学成为一门精密科学,需要对人的行为方式和影响行为变化的因素有更深入的了解。采用最新技术进行无干扰的数据收集和通过设计解决问题。个人内部设计与常规的个人间设计具有共同的方法要求,但需要特定的方法考虑。N比1评估设计适用于许多(但不是全部)干预措施。为了使健康心理学发展成为一门精密科学,需要对人的行为模式和影响行为变化的因素有更深入的了解。采用最新技术进行无干扰的数据收集和通过设计解决问题。个人内部设计与常规的个人间设计具有共同的方法要求,但需要特定的方法考虑。N-of-1评估设计适用于许多(但不是全部)干预措施。为了使健康心理学发展成为一门精密科学,需要对人的行为模式和影响行为变化的因素有更深入的了解。
