结果来自一项大型（n = 3，402）四组随机试验，以增加国家癌症研究所（NCI）癌症信息服务（CIS）使用定制印刷材料的呼叫者中的水果和蔬菜消费。在一次包括简短教育信息（BEM）的基线电话访谈之后，参与者在CIS办公室内被随机分配到四组之一：单一非定制（SU）组-一套非定制材料;单一定制（ST）组-一本定制小册子;多个定制（MT）组四份定制材料;多重再定制（MRT）组-第四组根据5个月随访时获得的新信息进行再定制。在基线后5个月（n = 2，233）和12个月（n = 1，927）进行随访电话访谈。主要结果测量是使用七项食物频率问卷自我报告的水果和蔬菜消费量。在12个月随访时，0.21份的组间存在显著的线性趋势（p = 0.0002）。然后对特定的嵌套假设进行检验，结果显示SU（5.07）与MT（5.64）（p = 0.002）和SU与MRT（5.71; p < 0.001）之间存在显著的平均服务差异。尽管ST组的平均值（5.40）大于SU组（5.07），但差异无统计学意义（p = 0.07），MT与MRT之间无差异（p = 0.69）。接受量身定制材料的人中有更高比例的人报告说，他们阅读了所有的材料，并认为这些材料是专门为他们编写的。实验条件下没有发现差异的印刷材料的感知有用性或动机的影响。在这项试验中，MT印刷材料在增加水果和蔬菜（FV）消费方面比SU材料更有效。这种影响的干预机制值得进一步研究。与纵向基线剪裁相比，重新剪裁没有产生显着差异。
Results are reported from a large (n = 3,402) four-group randomized trial to increase fruit and vegetable consumption among callers to the National Cancer Institute's (NCI's) Cancer Information Service (CIS) using tailored print materials. Following a baseline telephone interview, which included a brief educational message (BEM), participants were assigned randomly, within CIS offices to one of four groups: single untailored (SU) group-one untailored set of materials; single tailored (ST) group-one tailored booklet; multiple tailored (MT) group four tailored materials; and multiple retailored (MRT) group-four tailored materials with retailoring based on new information obtained at 5 months follow-up. Follow-up telephone interviews were conducted at 5 (n = 2,233) and 12 months (n = 1,927) after baseline. The main outcome measure was self reported fruit and vegetable consumption using a seven-item food frequency questionnaire. At 12 months follow-up, there was a significant linear trend across groups of 0.21 servings (p = 0.0002). Specific nested hypotheses then were tested and revealed significant mean serving differences between SU (5.07) vs. MT (5.64) (p = 0.002) and SU vs. MRT (5.71; p < 0.001). Although the mean for ST (5.40) was greater than that for SU (5.07), the difference was not statistically significant (p = 0.07), and no difference was found between MT vs. MRT (p = 0.69). A higher proportion of recipients of tailored materials reported reading all of the materials and believing that they were written especially for them. No differences by experimental condition were found for the perceived usefulness or motivational impact of the print materials. In this trial, MT print materials were more effective at increasing fruit and vegetable (FV) consumption than were SU materials. The intervention mechanisms responsible for this effect merit further research. Retailoring did not produce a significant difference when compared with longitudinal baseline tailoring.
