Abstract

OBJECTIVE

Investigate associations between quantity, content and specificity of action-plans and weight loss in a diabetes prevention study.

DESIGN

Prospective cohort study nested within a randomised controlled trial. Participants completed action-planning worksheets during intervention sessions.

MAIN OUTCOME MEASURES

Action-plans were coded in terms of: number of plans set, their content, and specificity. Multivariate regression analyses assessed associations with weight loss at four-months.

RESULTS

890 planning-worksheets from 106 participants were analysed. Participants wrote a mean of 2.12 (SD = 1.20) action-plans per worksheet, using a mean of 2.20 (SD = 0.68) specificity components per action-plan. Quantity of action-plans per worksheet decreased over time (r = -0.137, < 0.001) and increased quantity was associated with reduced specificity [r = -.215, < 0.001]. Walking (34.9% of action-plans) and reducing high fat/sugar snacks (26.1%) were the most commonly planned lifestyle actions. In multivariate modelling, increased quantity of action-plans was associated with greater weight loss (R2 = 0.135, Unstandardised Beta = 0.144, = 0.002). Specificity was not significantly associated with weight-loss ( = 0.096).

CONCLUSION

Producing more action-plans was associated with greater weight loss. Further research should directly compare more versus less specific action-plans and explore ways to sustain engagement in action-planning. Our findings imply that participants should freely set numerous action-plans, rather than being encouraged to focus on specificity.

摘要

目的

在糖尿病预防研究中，调查行动计划的数量、内容和针对性与体重减轻之间的关联。

设计

嵌套在随机对照试验中的前瞻性队列研究。参与者在干预期间完成行动计划工作表。

主要观察指标

行动计划根据以下方面进行编码：设定的计划数量、内容和针对性。多变量回归分析评估了与四个月时体重减轻的关联。

结果

对 106 名参与者的 890 份计划工作表进行了分析。参与者平均在每份工作表上写了 2.12 项（SD=1.20）行动计划，每项行动计划平均使用 2.20 项（SD=0.68）针对性组件。每份工作表上的行动计划数量随时间减少（r=-0.137， < 0.001），增加的数量与降低的针对性相关[ r=-0.215， < 0.001]。步行（34.9%的行动计划）和减少高脂肪/高糖零食（26.1%）是最常计划的生活方式行动。在多变量建模中，更多的行动计划与更大的体重减轻相关（R2=0.135，未标准化β=0.144， = 0.002）。针对性与体重减轻无显著相关性（ = 0.096）。
