尽管有证据表明，目标设定是有价值的身体活动促进，最近的研究强调了一个潜在的过度简化，在应用这种行为改变技术。虽然更困难的绩效目标可能会引发更高的体力活动水平，但更高的绩效目标可能同时更难以实现，这可能会降低长期动力。本研究考察了（a）成绩目标难度和体力活动之间的关系，（B）成绩目标难度和目标实现之间的关系。这项研究使用了来自非活动超重成年人（n = 20）的电子健康干预的数据。研究持续时间包括2周的基线期和80天的干预期。在干预过程中，参与者接受了一个每日步数目标，该目标是通过采取参与者的基线身体活动中位数（即，步数）乘以范围从1到2.6的伪随机因子。通过将每天的步数除以当天规定的目标来推断每天的目标实现的连续测量。线性和广义加性模型适合每个参与者。结果证实，对于参与研究的大多数参与者，表现目标困难与体力活动（n = 14）呈正相关，但同时，与目标实现（n = 19）呈负相关。这些关联主要是线性的。在日常水平上，设定更高的身体活动目标会导致更高的身体活动水平，但同时降低目标实现率。
Despite evidence that goal setting is valuable for physical activity promotion, recent studies highlighted a potential oversimplification in the application of this behavior change technique. While more difficult performance goals might trigger higher physical activity levels, higher performance goals might concurrently be more difficult to achieve, which could reduce long-term motivation. This study examined (a) the association between performance goal difficulty and physical activity and (b) the association between performance goal difficulty and goal achievement. This study used data from an e-Health intervention among inactive overweight adults (n = 20). The study duration included a 2-week baseline period and an intervention phase of 80 days. During the intervention, participants received a daily step goal experimentally manipulated by taking participants’ baseline physical activity median (i.e., number of steps) multiplied by a pseudorandom factor ranging from 1 to 2.6. A continuous measure of goal achievement was inferred for each day by dividing the daily number of steps by the goal prescribed that day. Linear and generalized additive models were fit for each participant. The results confirm that, for a majority of the participants involved in the study, performance goal difficulty was positively and significantly associated with physical activity (n = 14), but, concurrently, negatively and significantly associated with goal achievement (n = 19). These associations were mainly linear. At the daily level, setting a higher physical activity goal leads to engaging in higher physical activity levels, but concurrently lower goal achievement.
