Motivational theory-based interventions are known to be effective for increasing physical activity (PA) in the general population but their effects in people with severe mental illness are poorly understood. Therefore, we conducted a meta-analysis on the effect of these interventions on PA and cardiometabolic risk factors. A systematic search of randomized controlled trials through 6 databases was carried out from inception to March 2019. Analyses were conducted using random-effect models. Weighted mean difference (WMD) were used as effect size when outcomes had the same units, otherwise Hedge's g was used. Fourteen articles including 2128 participants were identified. Motivational theory-based interventions were effective in increasing PA (g = 0.27, 95%CI[0.03; 0.51], p = .003), reducing weight (WMD = -1.87 kg, 95%CI[-2.98; -0.76], p = .001), body mass index (WMD = -0.82 kg/m, 95%CI[-1.23; -0.41], p = .009), waist circumference (WMD = -1.91 cm, 95%CI[-3.63; -0.18], p = .03) and fasting glucose (g = -0.17, 95%CI[-0.34; -0.001], p = .04). Larger effect sizes were found in interventions based on only one theoretical model of motivation. In conclusion, interventions using motivational theories are effective to improve PA levels and the cardiometabolic health profile of people with severe mental illness.

基于动机理论的干预措施已被证明在普通人群中增加身体活动（PA）是有效的，但它们在严重精神疾病患者中的效果知之甚少。因此，我们对这些干预措施对 PA 和心血管代谢风险因素的影响进行了荟萃分析。通过 6 个数据库对从开始到 2019 年 3 月的随机对照试验进行了系统搜索。使用随机效应模型进行分析。当结果具有相同单位时，使用加权均数差（WMD）作为效应大小，否则使用 Hedge's g。确定了 14 篇文章，共包括 2128 名参与者。基于动机理论的干预措施在增加 PA 方面是有效的（g=0.27，95%CI[0.03; 0.51]，p=0.003），降低体重（WMD=-1.87kg，95%CI[-2.98; -0.76]，p=0.001），体重指数（WMD=-0.82kg/m，95%CI[-1.23; -0.41]，p=0.009），腰围（WMD=-1.91cm，95%CI[-3.63; -0.18]，p=0.03）和空腹血糖（g=-0.17，95%CI[-0.34; -0.001]，p=0.04）。基于单一动机理论模型的干预措施效果更大。总之，使用动机理论的干预措施可以有效提高严重精神疾病患者的 PA 水平和心血管代谢健康状况。系统评价注册：CRD42018104445。
