BACKGROUND Physical inactivity is a key contributor to the global burden of disease and disproportionately impacts the wellbeing of people experiencing mental illness. Increases in physical activity are associated with improvements in symptoms of mental illness and reduction in cardiometabolic risk. Reliable and valid clinical tools that assess physical activity would improve evaluation of intervention studies that aim to increase physical activity and reduce sedentary behaviour in people living with mental illness. METHODS The five-item Simple Physical Activity Questionnaire (SIMPAQ) was developed by a multidisciplinary, international working group as a clinical tool to assess physical activity and sedentary behaviour in people living with mental illness. Patients with a DSM or ICD mental illness diagnoses were recruited and completed the SIMPAQ on two occasions, one week apart. Participants wore an Actigraph accelerometer and completed brief cognitive and clinical assessments. RESULTS Evidence of SIMPAQ validity was assessed against accelerometer-derived measures of physical activity. Data were obtained from 1010 participants. The SIMPAQ had good test-retest reliability. Correlations for moderate-vigorous physical activity was comparable to studies conducted in general population samples. Evidence of validity for the sedentary behaviour item was poor. An alternative method to calculate sedentary behaviour had stronger evidence of validity. This alternative method is recommended for use in future studies employing the SIMPAQ. CONCLUSIONS The SIMPAQ is a brief measure of physical activity and sedentary behaviour that can be reliably and validly administered by health professionals.

评估精神疾病患者的体育锻炼：23个国家的简单体育锻炼问卷（SIMPAQ）的信度和效度。

背景技术缺乏运动是导致全球疾病负担的关键因素，并且不成比例地影响患有精神疾病的人们的健康。体育活动的增加与精神疾病症状的改善和心脏代谢风险的降低有关。评估身体活动的可靠有效的临床工具将改善干预研究的评估，这些研究旨在增加精神活动患者的身体活动并减少久坐行为。方法由多学科国际工作组开发的五项简单体育锻炼问卷（SIMPAQ）是一种临床工具，用于评估精神病患者的体育锻炼和久坐行为。招募了诊断为DSM或ICD精神疾病的患者，两次间隔一周，分别完成SIMPAQ。参与者佩戴了Actigraph加速度计并完成了简短的认知和临床评估。结果SIMPAQ有效性的证据是根据加速度计得出的体力活动进行评估的。数据来自1010名参与者。SIMPAQ具有良好的重测可靠性。中度剧烈运动的相关性与一般人群样本中的研究相当。久坐行为项的有效性证据不充分。计算久坐行为的另一种方法具有更强的有效性证据。建议在使用SIMPAQ的未来研究中使用此替代方法。
