需要研究针对久坐行为的干预措施，并使用适当的行为改变工具。目前的研究使用收敛顺序混合方法（QUAN + quality）来探索静坐行为干预期间工具的使用情况。数据来自一项双臂随机久坐行为干预试验。参与者使用了许多干预工具（例如，提示和站立式办公桌）。单独的混合效应回归模型通过两个干预目标探索工具数量变化和工具使用频率之间的关联：坐着时间的变化和从坐到站的转换次数。定性数据探讨了参与者对干预工具的态度。在调整工具数量后，工具使用总量的变化与坐下时间之间存在显著关系（β = - 12.86,p= 0.02），表明工具使用增加一个单位与坐下时间减少近13分钟相关。相比之下，在调整工具使用频率后，工具数量的变化与坐下时间之间存在显著的正相关（β = 63.70,p= .001），这表明增加工具数量而不增加工具使用频率与更多的坐下时间相关。24个半结构化访谈被编码，主题分析揭示了与工具使用相关的四个主题：(a)提示破坏行为；(b)符合目标的工具；(c)坐转站的工具无效；(d)工具的使用随着时间的推移而进化。专注于有效工具的参与者在减少坐着时间方面更成功。让参与者增加从站到站的转换的工具基本上是无效的。本研究注册于临床试验号：NCT02544867
Research is needed on interventions targeting sedentary behavior with appropriate behavior-change tools. The current study used convergent sequential mixed methods (QUAN + qual) to explore tool use during a edentary behavior intervention. Data came from a two-arm randomized sedentary behavior pilot intervention. Participants used a number of intervention tools (e.g., prompts and standing desks). Separate mixed-effects regression models explored associations between change in number of tools and frequency of tool use with two intervention targets: change in sitting time and number ofsit-to-stand transitionsovertime. Qualitative data explored participants’ attitudes towards intervention tools. There was a significant relationship between change in total tool use and sitting time after adjusting for number of tools (β = −12.86,p= .02), demonstrating that a one-unit increase in tool use was associated with an almost 13 min reduction in sitting time. In contrast, there was a significant positive association between change in number of tools and sitting time after adjusting for frequency of tool use (β = 63.70,p= .001), indicating that increasing the number of tools without increasing frequency of tool use was associated with more sitting time. Twenty-four semistructured interviews were coded and a thematic analysis revealed four themes related to tool use: (a) prompts to disrupt behavior; (b) tools matching the goal; (c) tools for sit-to-stand were ineffective; and (d) tool use evolved over time. Participants who honed in on effective tools were more successful in reducing sitting time. Tools for participants to increasesit-to-stand transitionswere largely ineffective.This study is registered at clincialtrials.gov.Identifier:NCT02544867
