We have had the impression that patients with spinal cord injury (SCI) experience fewer marriages and more divorces than their noninjured counterparts. To test this impression statistically, we examined the influence of SCI in association with other select variables on the marital status of 276 patients injured between 1973 and 1980 and treated at the University of Alabama in Birmingham Spinal Cord Injury Care System. The expected numbers of marriages and divorces in the study population were based on comparison with reported marriage and divorce rates for the general US population. Discriminant analysis was employed to identify variables associated significantly with a postinjury change in marital status. Substantially fewer marriages and more divorces occurred than were expected (p less than 0.05). No variables were associated significantly with marrying within three years of injury. However, divorcing patients were significantly more likely to be young black women who had been previously divorced, had no children, and had Barthel scores of less than 80. Using the most effective combination of these variables, 38.7% of the variance was explained, and the postinjury marital status of 81.5% of patients married at injury was predicted correctly. While other determinants of postinjury marital status undoubtedly exist, the likelihood of divorce can be assessed using a comparatively small set of predictor variables.
我们一直有种印象，即脊髓损伤（SCI）患者的婚姻数量比未受伤的同龄人少，离婚的情况则更多。为了从统计学上验证这一印象，我们研究了脊髓损伤与其他选定变量对1973年至1980年间在阿拉巴马大学伯明翰分校脊髓损伤护理系统接受治疗的276名患者婚姻状况的影响。研究人群中结婚和离婚的预期数量是基于与美国总体人口报告的结婚和离婚率进行比较得出的。采用判别分析来确定与受伤后婚姻状况变化显著相关的变量。实际发生的结婚数量明显少于预期，离婚数量则多于预期（p小于0.05）。没有变量与受伤后三年内结婚显著相关。然而，离婚的患者更有可能是年轻的黑人女性，她们此前已经离婚，没有孩子，且巴氏指数得分低于80。使用这些变量的最有效组合，可以解释38.7%的方差，并且能够正确预测81.5%受伤时已婚患者受伤后的婚姻状况。虽然受伤后婚姻状况的其他决定因素无疑存在，但离婚的可能性可以通过相对较少的一组预测变量来评估。
