目的：这项研究测试了计划和以伴侣为基础的干预措施在六个月内促进身体活动的有效性。方法：将257名地方政府(理事会)员工随机分配到4种条件(合作实施意向；仅合作伙伴；实施意向；控制组)，在完成基线措施前和在1、3和6个月的随访中。结果测量包括有效的体力活动自我报告测量：国际体力活动问卷(iPAQ；Craig等人，2003年)和自我报告步行和运动表(斯维特；Prestwich等人，2012年)；心理社会中介(享乐、意图、自我效能、社会影响)；体重和腰围(基线和6个月)。结果：在1个月、3个月和6个月的随访中，除了减掉最多的体重外，有证据表明，合作实施意向组的参与者比其他三组的参与者更活跃。在实施意向和仅限合作伙伴的条件下，这些人在大多数措施上的表现并不优于控制组。结论：协作性实施意向代表了改变有助于减肥的重要健康行为的潜在有用的干预措施。
Objective: The research tested the efficacy of planning and partner-based interventions to promote physical activity over six months. Method: Local government (council) employees (N = 257) were randomly allocated to one of four conditions (collaborative implementation intentions; partner-only; implementation intentions; control group) before completing measures at baseline and follow-ups at 1, 3 and 6 months. Outcome measures comprised validated self-report measures of physical activity: the International Physical Activity Questionnaire (IPAQ; Craig et al., 2003) and Self-Report Walking and Exercise Tables (SWET; Prestwich et al., 2012); psychosocial mediators (enjoyment, intention, self-efficacy, social influence); weight and waist size (baseline and 6 months only). Results: As well as losing the most weight, there was evidence that participants in the collaborative implementation-intention group were more physically active than each of the other three groups at 1-, 3- and 6-month follow-ups. Those in the implementation-intention and partner-only conditions did not outperform the control group on most measures. Conclusion: Collaborative implementation intentions represent a potentially useful intervention to change important health behaviors that help reduce weight.
