The EXOFFIT study compared the effectiveness of three time-matched exercise interventions in women with obesity for improving cardiorespiratory fitness. To best inform future research, evaluation of the interventions' acceptability is needed. Previous research has been inconsistent with methods and reporting of acceptability. Thus, the theoretical framework of acceptability (TFA) can be utilized to ensure that all aspects of acceptability are evaluated. No study to date in women with obesity has utilized the TFA in conjunction with quantitative data (i.e., frequencies of themes) to highlight the aspects of interventions that may be most important for participants.
This study aimed to examine the acceptability of the EXOFFIT program and gain insight into the participants' experience of participation, their perspective on the acceptability of trial procedures and interventions and gather their feedback on program changes.
A mixed-methods approach was employed. Thirty-eight participants who completed the exercise interventions were interviewed and completed a self-reported exit questionnaire. Interviews were transcribed verbatim and analyzed in three phases: emergent themes were agreed upon, then mapped to the TFA constructs and the frequencies of each construct and theme were presented as counts. Data collected from the exit questionnaire were collated and reported using descriptive statistics.
All seven TFA constructs were identified in the analysis. The EXOFFIT program was found to have a high level of acceptability, with affective attitude, perceived effectiveness and self-efficacy being the most reported constructs. The burden and opportunity costs associated with the program were mainly related to family commitments and support needed to participate. Any negative impact of participation was noted to be outweighed by the perceived benefits.
The results of this study will inform the development of future programs with women with obesity and support the consideration of the TFA constructs from the outset of study design.Clinical Trial Registration Number: ISRCTN13517067.
EXOFFIT研究比较了三种时间匹配的运动干预措施对肥胖女性改善心肺适能的有效性。为了更好地指导未来的研究，需要对这些干预措施的可接受性进行评估。以往的研究在可接受性的方法和报告方面并不一致。因此，可以利用可接受性理论框架（TFA）来确保对可接受性的各个方面进行评估。迄今为止，尚无针对肥胖女性的研究将TFA与定量数据（即主题频率）结合使用，以突出对参与者可能最重要的干预措施方面。
本研究旨在检验EXOFFIT项目的可接受性，并深入了解参与者的参与体验、他们对试验程序和干预措施可接受性的看法，并收集他们对项目变更的反馈。
采用混合方法。对38名完成运动干预的参与者进行了访谈，并完成了一份自我报告的退出问卷。访谈内容逐字转录，并分三个阶段进行分析：确定出现的主题，然后将其映射到TFA结构，并将每个结构和主题的频率以计数形式呈现。从退出问卷中收集的数据进行整理，并使用描述性统计进行报告。
分析中确定了所有七个TFA结构。发现EXOFFIT项目具有较高的可接受性，情感态度、感知有效性和自我效能是报告最多的结构。与该项目相关的负担和机会成本主要与家庭责任和参与所需的支持有关。参与者认为，参与带来的任何负面影响都被感知到的好处所抵消。
本研究结果将为未来针对肥胖女性的项目开发提供参考，并支持在研究设计之初就考虑TFA结构。临床试验注册号：ISRCTN13517067。
