Background

Schizophrenia is associated with a more than doubled risk of death from cardiovascular disease (CVD). Risk factors for CVD include low levels of physical activity, sedentary behaviour and sleep problems. These risk factors are not systematically assessed by health services.

Aims

Examine the feasibility, acceptability, validity and reliability of tools measuring physical activity, sedentary behaviour and sleep.

Methods

Thirty participants with schizophrenia measured their physical activity, sedentary behaviour and sleep by wearing ActiGraph wGT3X-BT accelerometers on their wrist and waist, and recorded their sleep using the SleepBot smartphone app for 7 days. After 7 days they completed the 5-item Simple Physical Activity Questionnaire (SIMPAQ) to retrospectively measure their physical activity and sedentary behaviour over the study period. Concurrent SIMPAQ and SleepBot validity and inter-rater reliability were assessed against accelerometer-derived measures of physical activity, sedentary behaviour and sleep. A qualitative interview was conducted at the end of the study to assess acceptability.

Results

The tools were feasible: 93% of participants provided valid wear-time accelerometry data and 83% provided SleepBot data. The SIMPAQ showed moderate concurrent validity but poor agreement for moderate-vigorous physical activity (MVPA) and moderate validity and agreement as a measure of sedentary behaviour. The SleepBot app showed poor concurrent validity and agreement for measures of sleep. The qualitative interviews demonstrated the tools were acceptable.

Conclusion

Monitoring physical activity, sedentary behaviour and sleep by accelerometry, smartphone and questionnaire was feasible and acceptable to people with schizophrenia. The SIMPAQ could be a valid and appropriate tool for routine clinical use.

检查精神分裂症患者身体活动、久坐行为和睡眠措施的可行性、可接受性、有效性和可靠性

背景

精神分裂症与心血管疾病 (CVD) 死亡风险增加一倍以上有关。心血管疾病的危险因素包括低水平的体力活动、久坐行为和睡眠问题。卫生服务机构没有系统地评估这些风险因素。

宗旨

检查测量身体活动、久坐行为和睡眠的工具的可行性、可接受性、有效性和可靠性。

方法

30 名精神分裂症参与者通过在手腕和腰部佩戴 ActiGraph wGT3X-BT 加速度计来测量他们的身体活动、久坐行为和睡眠，并使用 SleepBot 智能手机应用程序记录他们 7 天的睡眠。7 天后，他们完成了 5 项简单体力活动问卷 (SIMPAQ)，以回顾性测量他们在研究期间的体力活动和久坐行为。对照来自加速度计的体力活动、久坐行为和睡眠的测量，同时评估了 SIMPAQ 和 SleepBot 的有效性和评分者间的可靠性。在研究结束时进行了定性访谈以评估可接受性。

结果

这些工具是可行的：93% 的参与者提供了有效的磨损时间加速度测量数据，83% 的参与者提供了 SleepBot 数据。SIMPAQ 表现出中等的并发有效性，但对于中等强度的体育活动 (MVPA) 和中等有效性和一致性作为久坐行为的衡量标准较差。SleepBot 应用程序在睡眠测量方面的并发有效性和一致性较差。定性访谈表明这些工具是可以接受的。

结论

通过加速度计、智能手机和问卷监测身体活动、久坐行为和睡眠对精神分裂症患者来说是可行和可接受的。SIMPAQ 可能是常规临床使用的有效且适当的工具。
