Intrinsic values and priorities influence decision-making and are, therefore, important to consider explicitly in intervention development. Although health is generally considered an important value, individuals often make unhealthy choices, indicating a values disconnect.
To investigate how becoming aware of a disconnect between the value assigned to health and the effort devoted to health is related to intentions and commitment for behavioural change and physical activity among inactive adults.
We performed a secondary exploratory analysis on previously collected data. The intervention included a values exercise based on the Disconnected Values Model (DVM) that made disconnected values explicit to participants in two study arms. We compared participants with a disconnect ( = 138) with participants without a disconnect ( = 101) regarding intentions and commitment for behavioural change and physical activity and sitting time 2-4 weeks follow-up. Logistic and linear regression analyses were performed to analyse the data.
Between-group differences were found for the intention to devote more effort to health (OR = 3.75; 95%CI: 2.05; 6.86) and for the intention to become more physically active (OR = 2.21; 95%CI: 1.10; 4.46), indicating that significantly more participants with a disconnect were motivated to change, compared to participants without a disconnect. No between-group differences were found for commitment, intention strength, follow-up physical activity and sitting time.
Making explicit a disconnect regarding health in an active choice intervention was associated with intentions to become more physically active. Still, it did not translate in significant behaviour change at 2-4 weeks follow-up.

内在价值观和优先事项会影响决策，因此在干预措施的制定过程中明确加以考虑很重要。尽管健康通常被视为一项重要价值，但个体常常做出不健康的选择，这表明存在价值观脱节的情况。
调查意识到赋予健康的价值与为健康付出的努力之间的脱节如何与不活跃成年人的行为改变意图、承诺以及身体活动相关。
我们对先前收集的数据进行了二次探索性分析。干预措施包括一项基于脱节价值观模型（DVM）的价值观练习，该练习让两个研究组的参与者明确了脱节的价值观。我们比较了有脱节情况的参与者（n = 138）和无脱节情况的参与者（n = 101）在行为改变意图、承诺以及身体活动和久坐时间方面的情况，随访时间为2至4周。进行了逻辑回归和线性回归分析以分析数据。
在为健康付出更多努力的意图方面（比值比[OR] = 3.75；95%置信区间[CI]：2.05；6.86）以及在增加身体活动的意图方面（OR = 2.21；95%CI：1.10；4.46）发现了组间差异，这表明与无脱节情况的参与者相比，有脱节情况的参与者中有更多人有动力去改变。在承诺、意图强度、随访期间的身体活动和久坐时间方面未发现组间差异。
在积极选择干预中明确健康方面的脱节与增加身体活动的意图相关。然而，在2至4周的随访中，这并未转化为显著的行为改变。
