Despite the considerable growth in mindfulness-based research in the field of psychosis, few attempts have been made to validate mindfulness instruments in this population. This study aimed to evaluate the factorial structure, internal consistency, construct validity, and longitudinal measurement invariance of the Mindful Attention Awareness Scale (MAAS) in a sample of individuals with first-episode psychosis (FEP). In a sample of 150 individuals with remitted FEP, the present study explored the factor structure, measurement invariance, reliability, convergent and discriminant validity of the MAAS. Confirmatory factor analysis supported a single-factor solution, which showed temporal stability, excellent internal consistency reliability (Cronbach’s α = .92; McDonald’s ω = .93), and theoretically coherent convergent and discriminant validity with measures of well-being, satisfaction with life, savoring, self-compassion, depression, anxiety, stress, and positive symptoms. Overall, the psychometric properties of the MAAS were similar to those described in previous validation studies, thus supporting the value of this instrument to assess the dimension of attention and awareness to the present moment in individuals with FEP.

第一集精神病样本中正念注意意识量表 (MAAS) 的心理测量学特性。

尽管精神病领域基于正念的研究取得了长足的发展，但很少有人尝试在这一人群中验证正念工具。本研究旨在评估首发精神病 (FEP) 个体样本中正念注意意识量表 (MAAS) 的因子结构、内部一致性、结构效度和纵向测量不变性。本研究以 150 名 FEP 缓解的个体为样本，探讨了 MAAS 的因子结构、测量不变性、可靠性、收敛效度和判别效度。验证性因素分析支持单因素解决方案，该解决方案显示出时间稳定性、出色的内部一致性可靠性（Cronbach's α = .92；McDonald's ω = .93），在幸福感、生活满意度、品味、自我同情、抑郁、焦虑、压力和阳性症状等指标方面具有理论上一致的收敛和区分效度。总体而言，MAAS 的心理测量学特性与之前的验证研究中描述的相似，因此支持该工具在评估 FEP 患者当前注意力和意识维度方面的价值。
