Computer tailoring and motivational interviewing show promise in promoting lifestyle change, despite few head-to-head comparative studies.
Vitalum is a randomized controlled trial in which the efficacy of these methods was compared in changing physical activity and fruit and vegetable consumption in middle-aged Dutch adults.
Participants (n = 1,629) were recruited via 23 general practices and randomly received either four tailored print letters, four motivational telephone calls, two of each type of intervention, or no information. The primary outcomes were absolute change in self-reported physical activity and fruit and vegetable consumption.
All three intervention groups (i.e., the tailored letters, the motivational calls, and the combined version) were equally and significantly more effective than the control group in increasing physical activity (hours/day), intake of fruit (servings/day), and consumption of vegetables (grams/day) from baseline to the intermediate measurement (week 25), follow-up 1 (week 47) and 2 (week 73). Effect sizes (Cohen's d) ranged from 0.15 to 0.18. Participants rated the interventions positively; interviews were more positively evaluated than letters.
Tailored print communication and telephone motivational interviewing or their combination are equally successful in changing multiple behaviors.
尽管针对比较研究的文献很少，但电脑定制和动机性访谈在促进生活方式改变方面显示出了一定的前景。
Vitalum 是一项随机对照试验，旨在比较这些方法在改变中年荷兰成年人的身体活动和水果与蔬菜摄入量方面的效果。
通过 23 家普通诊所招募参与者（n=1629），并随机分配至四个接受定制印刷信件、四个接受动机性电话访谈、两种干预类型各两个或不接受任何信息的组别。主要结果是自我报告的身体活动和水果与蔬菜摄入量的绝对变化。
所有三种干预组（即定制信件、动机性电话访谈和组合版本）在增加身体活动（小时/天）、水果摄入量（份/天）和蔬菜摄入量（克/天）方面均明显优于对照组，从基线到中期测量（第 25 周）、随访 1（第 47 周）和 2（第 73 周）。效果大小（Cohen's d）范围从 0.15 到 0.18。参与者对干预措施的评价为正面；访谈的评价明显优于信件。
定制印刷通讯和电话动机性访谈或两者的组合在改变多种行为方面同样有效。
