Abstract

Background and aims

Moderate to vigorous physical activity (MVPA) and sedentary behavior are important factors for somatic and mental health. However, less than half of the people with mental illness (MI) complies with the norms for physical activity. For improving their physical activity with interventions, accurate measurement methods are essential. Actigraphy and diaries are used to measure physical activity in people with a MI, but little is known about how they compare in this group. This study investigates the agreement between actigraphy and daily diaries for assessing MVPA and sedentary behavior in people with a MI.

Methods

As part of a pilot-RCT on a lifestyle intervention, twenty transdiagnostic outpatients wore actigraphy and filled in evening diaries for 2 × 14 days (before/after intervention period) (t = 429 paired observations), measuring daily minutes of MVPA and sedentary time. A mixed-model limits of agreement (LoA) method was used to calculate the mean bias between the measurement methods, which was compared to the clinical accepted difference (MVPA: 10 min, sedentary time: 60 min). Bland-Altman plots were examined on patterns.

Results

The mean bias between actigraphy and diaries was −29 min (95 % LoA −122 to 64) for MVPA and −165 min (95 % LoA −584 to 253) for sedentary time; diaries underreported more than clinically acceptable compared to actigraphy. Post-hoc analysis indicated that the bias differed between volume levels.

Conclusions

Actigraphy and daily diaries appear incomparable in MI. Follow-up research is needed to uncover the nature of these differences and ways to overcome them. Until then, it is recommendable to use both.

评估精神疾病患者的身体活动和久坐行为：活动记录仪和每日自我报告测量是否一致？

背景与目的中高强度体力活动（MVPA）和久坐行为是影响身心健康的重要因素。然而，只有不到一半的精神疾病患者（MI）遵守了身体活动的规范。为了通过干预措施改善他们的身体活动，精确的测量方法至关重要。活动记录仪和日记被用来测量心肌梗死患者的身体活动，但人们对它们在这一组中的比较情况知之甚少。方法作为一项生活方式干预的随机对照试验的一部分，20名跨诊断门诊患者在干预前/后2 × 14天（t = 429对观察）佩戴活动记录仪并填写夜间日记，测量每日MVPA分钟数和久坐时间。采用混合模型一致限（LoA）法计算测量方法之间的平均偏差，并将其与临床可接受差异（MVPA: 10 min，久坐时间：60 min）进行比较。Bland-Altman图在模式上进行检验。结果活动记录仪和日记的平均偏差MVPA为- 29 min (95% LoA - 122 ~ 64)，久坐时间为- 165 min (95% LoA - 584 ~ 253)；与活动描记术相比，日记少报多于临床可接受的。事后分析表明，不同音量水平的偏倚有所不同。结论在心肌梗死中，活动记录仪和日常日记似乎是不可比拟的，需要进一步的研究来揭示这些差异的本质和克服它们的方法。在此之前，建议两者都使用。

期刊介绍： The aims of Mental Health and Physical Activity will be: (1) to foster the inter-disciplinary development and understanding of the mental health and physical activity field; (2) to develop research designs and methods to advance our understanding; (3) to promote the publication of high quality research on the effects of physical activity (interventions and a single session) on a wide range of dimensions of mental health and psychological well-being (eg, depression, anxiety and stress responses, mood, cognitive functioning and neurological disorders, such as dementia, self-esteem and related constructs, psychological aspects of quality of life among people with physical and mental illness, sleep, addictive disorders, eating disorders), from both efficacy and effectiveness trials;
