A physically active lifestyle during midlife is critical to the maintenance of high physical functioning. This study tested whether an intervention that combined information with cognitive-behavioral strategies had a better effect on women's physical activity than an information-only intervention.
A 4-month longitudinal RCT comparing two brief interventions was conducted between July 2003 and September 2004. Analyses were completed in June 2008.
256 women aged 30-50 years in a large metropolitan area in Germany.
The study compared a health information intervention with an information + self-regulation intervention. All participants received the same information intervention; participants in the information + self-regulation group additionally learned a technique that integrates mental contrasting with implementation intentions.
Self-reported minutes of moderate-to-vigorous physical activity per week.
Participants in the information + self-regulation group were twice as physically active (i.e., nearly 1 hour more per week) as participants in the information group. This difference appeared as early as the first week after intervention and was maintained over the course of the 4 months. Participants in the information group slightly increased their baseline physical activity after intervention.
Women who learned a self-regulation technique during an information session were substantially more active than women who participated in only the information session. The self-regulation technique should be tested further as a tool for increasing the impact of interventions on behavioral change.
中年时期积极的生活方式对于维持较高的身体机能至关重要。本研究测试了一种将信息与认知行为策略相结合的干预措施对女性身体活动的影响是否优于仅提供信息的干预措施。
2003年7月至2004年9月期间进行了一项为期4个月的纵向随机对照试验，比较两种简短干预措施。分析于2008年6月完成。
德国一个大都市地区的256名年龄在30至50岁之间的女性。
该研究将健康信息干预与信息+自我调节干预进行了比较。所有参与者都接受了相同的信息干预；信息+自我调节组的参与者还学习了一种将心理对比与实施意图相结合的技巧。
每周自我报告的中度至剧烈身体活动分钟数。
信息+自我调节组的参与者身体活动量是信息组参与者的两倍（即每周多近1小时）。这种差异在干预后的第一周就出现了，并在4个月的过程中一直保持。信息组的参与者在干预后略微增加了其基线身体活动量。
在信息课程中学习了自我调节技巧的女性比仅参加信息课程的女性活动量明显更大。自我调节技巧应作为一种增强干预对行为改变影响的工具进行进一步测试。
