To further develop tailored interventions, their working mechanisms must be identified. In the present study, three tailored messages that each contained one potential working mechanism--personalization, adaptation or feedback--were compared with a standard information condition. Two hundred and two students who smoked tobacco daily were randomly divided over four conditions. After the computer pre-test questionnaire, they read the information in their condition and filled in the immediate post-test. After 4 months, they were sent a follow-up questionnaire assessing their quitting activity. The data show that personalization (44.5%) and feedback (48.7%), but not adaptation (28.6%), led to significantly more quitting activity after 4 months than did the standard information (22.9%). Moreover, the effect of condition on quitting activity was completely mediated by individuals' evaluations of the tailoring.
为了进一步开发量身定制的干预措施，必须确定其作用机制。在本研究中，将三条分别包含一种潜在作用机制（个性化、适应性或反馈）的量身定制信息与标准信息条件进行了比较。202名每天吸烟的学生被随机分为四种条件。在完成计算机预测试问卷后，他们阅读各自条件下的信息并填写即时后测问卷。4个月后，向他们发送一份评估其戒烟活动的后续问卷。数据显示，4个月后，个性化（44.5%）和反馈（48.7%）而非适应性（28.6%）导致的戒烟活动显著多于标准信息（22.9%）。此外，条件对戒烟活动的影响完全由个体对量身定制的评价所介导。
