The Mental Adjustment to Cancer (MAC) Scale is widely used to assess psychological response to cancer. There have been several attempts to replicate independently the original factor structure of the MAC. Evidence from these replication studies is reviewed. A re-analysis of the MAC Scale was conducted on a substantial new cohort in order to clarify the factor structure.
1255 patients with various cancer diagnoses completed the MAC Scale.
Two results emerged: first, that the original MAC dimension of Helplessness/Hopelessness is extremely stable and robust; second, that the original factors can be subsumed within two overarching (first order) factors relating to positive and negative adjustment scores.
The original MAC Scale remains a satisfactory measure of psychological outcome. Two-higher order factors representing global adjustment are now available to provide an overall summary measure alongside the original specific sub-scales.
癌症心理适应（MAC）量表被广泛用于评估对癌症的心理反应。已有多项独立尝试复制MAC的原始因子结构。本文回顾了这些复制研究的证据。为了阐明因子结构，对一个规模可观的新队列进行了MAC量表的重新分析。
1255例患有各种癌症诊断的患者完成了MAC量表。
得出了两个结果：第一，无助/绝望这一原始MAC维度极其稳定且可靠；第二，原始因子可以归入与积极和消极调整得分相关的两个总体（一阶）因子中。
原始MAC量表仍然是心理结果的一项令人满意的测量工具。现在有两个代表整体调整的高阶因子，可与原始的特定子量表一起提供总体概括性测量。
