ABSTRACT

This systematic review and intervention content analysis used behavioural science frameworks to characterise content and function of interventions targeting supermarket shoppers’ purchasing behaviour, and explore if coherence between content and function was linked to intervention effectiveness. Study eligibility: in-store interventions (physical supermarkets) with control conditions, targeting objectively measured food and/or non-alcoholic drink purchases, published in English (no date restrictions). Eleven electronic databases were searched; reference lists of systematic reviews were hand-searched. Methodological quality was assessed using the GATE checklist. A content analysis was performed to characterise intervention content and function, and theoretical coherence between these, using the Behaviour Change Wheel, Behaviour Change Techniques Taxonomy, and Typology of Interventions in Proximal Physical Micro-Environments (TIPPME). Forty-six articles (49 interventions) met inclusion criteria; 26 articles (32 interventions) were included in the content analysis. Twenty behaviour change techniques (BCTs), and four TIPPME intervention types were identified; three BCTs (‘Prompts/cues’, ‘Material incentive’, and ‘Material reward’) were more common in effective interventions. Nineteen interventions solely employed theoretically appropriate BCTs. Theoretical coherence between BCTs and intervention functions was more common in effective interventions. Effective interventions included price promotions and/or in-store merchandising. Future research should explore the effect of specific BCTs using factorial study designs.

摘要

这项系统回顾和干预内容分析使用行为科学框架来描述针对超市购物者购买行为的干预措施的内容和功能，并探讨内容和功能之间的一致性是否与干预效果相关。研究资格：具有控制条件的店内干预措施（实体超市），针对客观测量的食品和/或非酒精饮料购买量，以英文发布（无日期限制）。检索了十一个电子数据库；系统评价的参考文献清单是手工检索的。使用 GATE 检查表评估方法学质量。使用行为改变轮、行为改变技术分类法和近端物理微环境干预类型学 (TIPPME) 进行内容分析，以表征干预内容和功能以及它们之间的理论一致性。46 篇文章（49 项干预措施）符合纳入标准；内容分析中包含 26 篇文章（32 条干预措施）。确定了二十种行为改变技术 (BCT) 和四种 TIPPME 干预类型；三种 BCT（“提示/提示”、“物质激励”和“物质奖励”）在有效干预中更为常见。十九项干预措施仅采用理论上适当的 BCT。在有效的干预措施中，BCT 和干预功能之间的理论一致性更为常见。有效的干预措施包括价格促销和/或店内推销。未来的研究应该使用析因研究设计来探索特定 BCT 的效果。普洛斯彼罗注册号：CRD42017071065。
