Abstract

Purpose

The Mind Excessively Wandering Scale (MEWS) assesses excessive mind-wandering. This study evaluated the psychometric properties of the Persian 12-item MEWS (MEWS-12) among Iranian adolescents, focusing on factor structure, internal consistency, associations with external measures, known-groups validity, and gender measurement invariance.

Method

In this cross-sectional study, 506 adolescents aged 12–18 years completed the MEWS and measures of rumination, attentional control, mindfulness, depressive and anxiety symptoms, and positive and negative affect. All 15 original MEWS items were administered, with the developer-recommended 12-item version designated for primary analyses. The sample was randomly divided, with stratification by gender, into independent exploratory factor analysis (EFA; n = 254) and confirmatory factor analysis (CFA; n = 252) subsamples.

Finding

Parallel analysis favored a two-factor EFA solution accounting for 54% of the variance, with a factor correlation of 0.73. In CFA, the correlated two-factor model showed better fit than the unidimensional model, χ²(53) = 122.89, CFI = 0.971, TLI = 0.964, RMSEA = 0.072, 90% CI [0.056, 0.089], and SRMR = 0.054, although the factors were highly correlated (r = 0.858). Internal consistency was good (α = 0.893; ω = 0.917). Higher MEWS-12 scores were associated with greater depressive and anxiety symptoms, rumination, and negative affect, and with lower mindfulness and positive affect; the association with self-reported attentional control was small and non-significant. Adolescents at or above the selected GAD-7 and PHQ-9 symptom thresholds had higher MEWS-12 scores than those below the respective thresholds. Gender invariance analyses provided preliminary support for comparable measurement properties across girls and boys.

Conclusion

The findings provide preliminary evidence regarding the psychometric properties of the Persian MEWS-12 among Iranian adolescents. The two-factor representation should be interpreted cautiously given the substantial factor overlap. Further replication in independent samples and evaluation in longitudinal and clinically characterized studies are warranted.

伊朗青少年波斯语版过度走神量表的心理测量特性：一项验证性研究。

目的：过度走神量表（MEWS）评估过度走神。本研究评估了伊朗青少年波斯语12项MEWS （MEWS-12）的心理测量特性，重点关注因素结构、内部一致性、与外部测量的关联、已知组效度和性别测量的不变性。方法：采用横断面研究方法，对506名12-18岁的青少年进行MEWS测试，并对其进行反刍、注意控制、正念、抑郁和焦虑症状以及积极和消极情绪的测量。所有15个原始MEWS项目都被管理，开发人员推荐的12个项目版本被指定用于主要分析。样本按性别随机分层，分为独立探索性因子分析（EFA, n = 254）和验证性因子分析（CFA, n = 252）两个子样本。发现：平行分析倾向于双因素EFA解决方案，占方差的54%，因子相关系数为0.73。在CFA中，相关双因素模型的拟合效果优于单维模型，χ2(53) = 122.89, CFI = 0.971, TLI = 0.964, RMSEA = 0.072, 90% CI [0.056, 0.089], SRMR = 0.054，但各因素高度相关（r = 0.858）。内部一致性较好（α = 0.893; ω = 0.917）。MEWS-12得分越高，抑郁和焦虑症状、反刍和消极情绪越严重，正念和积极情绪越低；与自我报告的注意力控制的关联很小且不显著。达到或高于所选GAD-7和PHQ-9症状阈值的青少年MEWS-12得分高于低于所选阈值的青少年。性别不变性分析为女孩和男孩之间可比较的测量特性提供了初步支持。结论：本研究结果为伊朗青少年MEWS-12量表的心理测量特性提供了初步证据。考虑到大量因素重叠，应谨慎解释双因素表示。在独立样本和纵向和临床特征研究中进一步的复制和评估是有必要的。
