The Mental Adjustment to Cancer (MAC) scale was validated on a heterogeneous French sample of 317 cancer patients. Internal consistency was satisfactory for the original subscales (alpha coefficients=0.62-0.80), except for the Fatalism subscale (alpha=0.40). The intercorrelations of the subscales and the correlations between the subscales and Anxiety and Depression criteria were congruent with the values reported in the literature. Multidimensional Scaling revealed three positive and three negative subsets of items revealing adjustment to cancer. Congeneric factor analysis of the subsets was performed with LISREL 8.3 and only three of them (after discarding certain items) were retained: Fighting Spirit (FS) Hopelessness/Helplessness (HH) and Anxious Preoccupation (AP). A confirmatory hierarchical factor analysis on the 21 items included showed that FS measured positive adjustment to cancer and HH and AP measured negative adjustment. A differential adjustment hypothesis was proposed in order to explain the stability and instability of the measures of the diverse constructs. The three revised subscales showed the same validity pattern as the corresponding original scales, but the magnitude of the correlations was considerably improved with respect to the original subscales. The practical and the theoretical importance of FS, HH and AP are emphasized.
癌症心理调适（MAC）量表在317名法国癌症患者的异质性样本上进行了验证。除宿命论子量表（α = 0.40）外，原始子量表的内部一致性令人满意（α系数 = 0.62 - 0.80）。子量表之间的相互关联以及子量表与焦虑和抑郁标准之间的关联与文献报道的值一致。多维标度法揭示了揭示癌症调适的三个积极项目子集和三个消极项目子集。使用LISREL 8.3对子集进行同属因素分析，仅保留其中三个（剔除某些项目后）：斗志（FS）、绝望/无助（HH）和焦虑关注（AP）。对纳入的21个项目进行的验证性层次因素分析表明，FS测量了对癌症的积极调适，HH和AP测量了消极调适。为了解释不同构念测量的稳定性和不稳定性，提出了差异调适假设。三个修订后的子量表显示出与相应原始量表相同的效度模式，但与原始子量表相比，相关性的大小有了显著提高。强调了FS、HH和AP在实践和理论上的重要性。
