目标。目的：评价为成年女性量身定做的互联网+电子邮件体力活动干预的可行性和有效性。来自加利福尼亚州的健康和种族多样化的成年女性(N=156)(平均年龄=42.8岁，65%是高加索人)被随机分配到干预组(访问定制的网站和每周电子邮件)或等待名单对照组。参与者在基线、一个月、两个月和三个月时完成了基于网络的体力活动、行为变化阶段和心理社会变量的评估。数据是在2006-2007年期间收集的。多水平随机系数模型检验了变化率的组间差异。与对照组相比，干预组在三个月后增加了步行(每周+69分钟比+32分钟)和总的中等到剧烈的体力活动(每周+23分钟比-25分钟)。干预对行为改变阶段及其他心理社会变量均无影响。在不同种族的样本中，为成年女性量身定做的基于互联网的干预措施对步行和中等至剧烈的体力活动产生了积极影响。然而，考虑到对照组中缺乏可比的研究接触，这些发现应该谨慎对待。(C)2008 Elsevier Inc.保留所有权利。
Objective. To evaluate the feasibility and efficacy of an individually tailored, Internet-plus-email physical activity intervention designed for adult women.Method. Healthy and ethnically-diverse adult females (N=156) (mean age = 42.8 years, 65% Caucasian) from California were randomly assigned to an intervention (access to a tailored website and weekly emails) or wait-list control group. Participants completed web-based assessments of physical activity, stage of behavior change, and psychosocial variables at baseline, one month, two months, and three months. Data were collected during 2006-2007. Multilevel random coefficient modeling examined group differences in rates of change.Results. As compared to the control condition, the intervention group increased walking (+69 versus +32 min per week) and total moderate-to-vigorous physical activity (+23 versus -25 min per week) after three months. The intervention did not impact stage of behavior change or any of the other psychosocial variables.Conclusion. A tailored, Internet-based intervention for adult women had a positive effect on walking and moderate-to-vigorous physical activity in an ethnically-diverse sample. However, given the lack of comparable research contact in the control group, these findings should be taken cautiously. (C) 2008 Elsevier Inc. All rights reserved.
