Evidence increasingly links a high-fat, low-fiber diet to coronary heart disease and certain site cancers, indicating a need for large-scale dietary change. Studies showing the effectiveness of particular procedures in specific settings are important at this point. The present study, using an A-B-A-B design and sales data from computerized cash registers, replicated and extended previous work by showing that inexpensive prompts (i.e., signs and fliers) in a national fast-food restaurant could increase the sales of salads, a low-fat, high-fiber menu selection. Suggestions also are made pertinent to more widespread use of the procedures.
越来越多的证据表明，高脂肪、低纤维饮食与冠心病和某些部位的癌症有关，这表明需要进行大规模的饮食改变。在这一点上，展示特定程序在特定环境中的有效性的研究很重要。本研究采用A-B-A-B设计，并利用计算机收银机的销售数据，通过表明在全国性快餐店中使用廉价的提示（即招牌和传单）可以增加沙拉（一种低脂、高纤维的菜单选择）的销量，复制并扩展了先前的研究。还提出了与更广泛应用这些程序相关的建议。
