Relationships were examined between 13 predictor variables and two criteria of improvement in a program for problem drinker-drivers. Four measures of social background (income, educations, age, marital status), four measures of psychopathology based on the Minnesota Multiphasic Personality Inventory (MMPI), one measure of general alcoholism, and four indicators of treatment involvement served as predictor variables. Two factorially derived criteria served as outcome indicators, one reflecting general improvement, the other reflecting improved social adjustment, but a failure to reduce drinking. This second factor was interpreted as indicating resistance. Analysis included partial correlation and multiple regression, from which explained variance was completely partitioned into sources unique to each predictor, and sources shared by combinations of predictors. Results suggested that with other factors controlled, treatment involvement was linked both to improvement and to resistance. Similar conclusions were suggested for social background, but slightly different ones for psychopathology and alcoholism. Psychopathology was uniquely related to improvement; alcoholism, to resistance.
在一个针对问题饮酒驾驶者的项目中，研究了13个预测变量与两个改善标准之间的关系。四个社会背景指标（收入、教育程度、年龄、婚姻状况）、基于明尼苏达多相人格调查表（MMPI）的四个精神病理学指标、一个一般酗酒指标以及四个治疗参与度指标作为预测变量。两个通过因子分析得出的标准作为结果指标，一个反映总体改善情况，另一个反映社会适应能力改善但饮酒量未减少的情况。第二个因素被解释为表明存在抵触情绪。分析包括偏相关和多元回归，通过这些分析，可解释方差被完全分解为每个预测变量独有的来源以及预测变量组合所共有的来源。结果表明，在控制其他因素的情况下，治疗参与度与改善和抵触情绪均有关联。社会背景也得出了类似结论，但精神病理学和酗酒情况的结论略有不同。精神病理学与改善情况具有独特关联；酗酒则与抵触情绪有关。
