The Mini-Mental Adjustment to Cancer Scale (Mini-MAC) instrument is commonly used worldwide by professionals of oncology, but the scale has not, up to date, been validated in Arabic and Moroccan context, and there is an absence of data in the Moroccan population. This study aims to validate the Mini-MAC, translated and adapted to the Arabic language and Moroccan culture, in women with breast cancer.
Data were analyzed in two successive phases. First, exploratory factor analysis (EFA) was used to assess the factor structure in the pilot sample (N = 158). Then, this structure was confirmed in the validation sample (N = 203) using confirmatory factor analysis (CFA).
Confirmatory factor analysis confirmed Watson's original structure underlying the Mini-MAC items: Helpless/Hopeless, Anxious Preoccupation, Fighting Spirit, Cognitive Avoidance, and Fatalism. Absolute, incremental, and parsimonious fit indices showed a highly significant level of acceptance confirming a good performance of the measurement model. The instrument showed sufficient reliability and convergent validity demonstrated by acceptable values of composite reliability (CR =0.93-0.97), and average variance extracted (AVE = 0.66-0.93), respectively. The square roots of AVE were higher than factor-factor pairs correlations, and the Heterotrait-Monotrait ratio of correlations values were lesser than 0.85, indicating acceptable discriminant validity.
reliability; and both convergent and discriminant validity tests indicated that the Arabic version of the Mini-MAC had a good performance and may serve as a valid tool measuring psychological responses to cancer diagnosis and treatment.
Mini-Mental Adjustment to Cancer Scale（Mini-MAC）量表被全球范围内的肿瘤学专业人士广泛使用，但该量表尚未在阿拉伯语和摩洛哥语境中得到验证，摩洛哥人群中也缺乏相关数据。本研究旨在验证 Mini-MAC 在阿拉伯语和摩洛哥文化背景下在乳腺癌女性中的适用性。
数据分两个阶段进行分析。首先，在试点样本（N=158）中使用探索性因子分析（EFA）评估因子结构。然后，在验证样本（N=203）中使用验证性因子分析（CFA）确认该结构。
验证性因子分析证实了 Watson 提出的 Mini-MAC 项目的原始结构：无助/无望、焦虑关注、斗志、认知回避和宿命论。绝对、增量和简约拟合指数显示出高度显著的接受水平，证实了测量模型的良好表现。该工具具有足够的可靠性和收敛有效性，通过可接受的综合可靠性（CR=0.93-0.97）和平均方差提取（AVE=0.66-0.93）值分别得到证明。AVE 的平方根高于因子-因子对相关性，相关值的 Heterotrait-Monotrait 比值小于 0.85，表明具有可接受的判别有效性。
Mini-MAC 阿拉伯语版本的可靠性、收敛和判别有效性测试表明其具有良好的性能，可作为测量癌症诊断和治疗后心理反应的有效工具。
