这项先导性研究旨在测试在体力活动干预的最初几周内，每日步数的增加和日常步数的每日一致性是否可以预测结果。这是来自两项同时进行的研究的第二次分析，这两项研究测试了一种积极的心理学-动机访谈干预措施，以增加2型糖尿病患者的体力活动和积极情绪。在研究评估(基线、治疗结束和8周随访)时使用加速计测量步数，并在干预过程中由参与者使用提供的计步器每天测量步数。我们计算了从干预第1周到第3周的步数变化，以及前3周每天步数的变异性，使用最佳拟合回归线模拟它们的变化。多元回归分析检验了这些预测因素是否与治疗结束和8周随访时体力活动的变化有关。此外，我们使用最小p值方法探索了早期阶跃变化的特定截止点(例如，500步)的效用。在52名参与者中，第3周步数增加较大的患者在治疗结束和随访时活动增加。早期步骤的可变性与结果无关。提早增加500级和2000级的下限可能具有实际意义。对体力活动干预的早期反应似乎是一个有用的结果预测指标，可以用来在治疗早期确定那些不太可能在给定干预中成功的人。
This pilot study aimed to test whether increase in daily steps and day-to-day consistency in daily steps during the first several weeks of a physical activity intervention predicted outcomes. This was a secondary analysis from two concurrent studies testing a positive psychology-motivational interviewing intervention to increase physical activity and positive affect in individuals with type 2 diabetes. Steps were measured with accelerometers at study assessments (baseline, end-of-treatment, and 8-week follow-up), and were measured daily throughout the intervention by participants using provided pedometers. We calculated change in steps from intervention week 1 to week 3, along with variability in daily steps over the first 3 weeks, using the best fitting regression line modeling their change. Multiple regression analyses tested whether these predictors were associated with change in physical activity at the end of treatment and at 8-week follow-up. Additionally, we explored the utility of specific cutoffs (e.g., 500 steps) for early step change using a minimum p-value approach. In 52 participants, larger step increases by week 3 predicted activity increase at end-of-treatment and follow-up. Variability in early steps was not associated with outcomes. Early increase cutoffs of 500 and 2000 steps may have practical relevance. Early response to a physical activity intervention appears to be a useful predictor of outcome and could be used to identify those unlikely to succeed in a given intervention early in treatment.
