Mindfulness has been studied as a treatment option for a large range of psychological disorders and is associated with a multitude of positive psychological outcomes. There are now several scales for measuring mindfulness as both a trait and a state. As mindfulness potentially plays a critical role in maintaining physical activity habits, the State Mindfulness Scale for Physical Activity (SMS-PA) was developed to specifically measure mindfulness in a physical activity context. This study aimed to provide validity evidence for a German version of the SMS-PA (henceforth called SMS-PA-G) in a clinical sample.
We used baseline data from 129 participants in the randomised controlled trial 'New Ways to Cope with Depression'. The sample, which was screened for clinical depression symptoms, completed the SMS-PA-G and several other psychometric scales for capturing state mindfulness, self-efficacy, sense of coherence, anxiety, depression, and physical activity. We conducted reliability and item analyses and ran a confirmatory factor analysis. Also, we assessed construct validity through correlations with the abovementioned scales and through differences in SMS-PA scores between physically active and nonactive participants.
The mean SMS-PA-G score in our sample was 25.3 with a standard deviation of 8.5. The item and reliability analyses provided satisfactory Cronbach's alpha and discriminatory power values. The confirmatory factor analysis showed that physical activity mindfulness can best be described via a bifactor model, with specific mind and body factors and a general mindfulness factor. We found the expected relationships with the attention subscale of state mindfulness, self-efficacy, and sense of coherence but did not find them with the awareness subscale of state mindfulness, depression, and anxiety. As hypothesised, physically active participants exhibited higher SMS-PA-G values than nonactive participants.
The SMS-PA-G is an internally consistent test instrument that captures respondents' general physical activity mindfulness and their attention to mental and bodily events. Whereas validity evidence was generally supportive of the SMS-PA-G, its relationships with other constructs require further investigation.

正念已被作为多种心理障碍的一种治疗选择进行研究，并且与众多积极的心理结果相关联。现在有几种用于测量作为一种特质和一种状态的正念的量表。由于正念可能在维持身体活动习惯方面发挥关键作用，因此开发了身体活动状态正念量表（SMS-PA）来专门测量身体活动情境下的正念。本研究旨在为临床样本中的德语版SMS-PA（以下简称SMS-PA-G）提供效度证据。
我们使用了随机对照试验“应对抑郁的新方法”中129名参与者的基线数据。该样本经过临床抑郁症状筛查，完成了SMS-PA-G以及其他几个用于测量状态正念、自我效能感、连贯感、焦虑、抑郁和身体活动的心理测量量表。我们进行了信度和项目分析，并进行了验证性因素分析。此外，我们通过与上述量表的相关性以及身体活动参与者和不活动参与者之间SMS-PA分数的差异来评估结构效度。
我们样本中的SMS-PA-G平均得分为25.3，标准差为8.5。项目和信度分析提供了令人满意的克朗巴哈系数和区分度值。验证性因素分析表明，身体活动正念可以通过双因素模型得到最佳描述，包括特定的身心因素和一般正念因素。我们发现了与状态正念的注意子量表、自我效能感和连贯感的预期关系，但未发现与状态正念的觉察子量表、抑郁和焦虑的预期关系。正如所假设的，身体活动参与者的SMS-PA-G值高于不活动参与者。
SMS-PA-G是一种内部一致的测试工具，能够捕捉受访者的一般身体活动正念以及他们对心理和身体事件的关注。虽然效度证据总体上支持SMS-PA-G，但其与其他结构的关系需要进一步研究。
