The International Physical Activity Questionnaire (IPAQ) is a self-report tool commonly used in mental healthcare settings to assess physical activity. However, its validity has not yet been investigated in first-episode psychosis (FEP). The aim of this study was to examine the concurrent validity of the IPAQ compared with an objective real-life measure, the Sensewear Armband (SWA), in assessing moderate and vigorous physical activity (MVPA) in people with FEP. A secondary aim was to explore whether there are differences in correlates of the IPAQ vs SWA scores.
In total, 19 outpatients with FEP (15 men; 24.4 ± 5.1 years) wore an SWA for 5 full consecutive days, subsequently completed the IPAQ, performed a maximal cardiorespiratory fitness test and were assessed with the Positive and Negative Syndrome Scale (PANSS).
There was no significant correlation between time spent in MVPA according to the IPAQ and SWA. In contrast with SWA scores, there were no significant associations between IPAQ scores and cardiorespiratory fitness levels. No correlations with PANSS scores were observed in both measures.
The current results suggest that the IPAQ should be used with caution when assessing levels of MVPA in FEP. More accurate methods of measuring physical activity are needed in this population.
国际体力活动问卷（IPAQ）是一种常用于精神卫生保健机构的自我报告工具，用于评估体力活动。然而，其在首发精神病（FEP）中的有效性尚未得到研究。本研究旨在检验 IPAQ 与客观的现实生活测量（Sensewear 臂带（SWA））在评估 FEP 患者中中等和剧烈体力活动（MVPA）时的同时效度。次要目的是探讨 IPAQ 与 SWA 评分相关因素的差异。
共纳入 19 名首发精神病患者（15 名男性；24.4±5.1 岁），连续 5 天佩戴 SWA，随后完成 IPAQ，进行最大心肺功能测试，并进行阳性和阴性综合征量表（PANSS）评估。
根据 IPAQ 和 SWA 评估的 MVPA 时间之间无显著相关性。与 SWA 评分相比，IPAQ 评分与心肺功能水平之间无显著关联。在两种测量方法中，均未观察到与 PANSS 评分的相关性。
目前的结果表明，在评估首发精神病患者的 MVPA 水平时，应谨慎使用 IPAQ。该人群需要更准确的体力活动测量方法。
