The paper examines the background to 210 live exnuptial births studied in the first phase of the Christ-church Child Development Study. The results show: 1. That nearly half of the children had been conceived within cohabiting situations. 2. That nearly one in five ex-nuptial children was the result of a planned pregnancy. 3. Maternal reactions to the birth and pregnancy varied with the mother's situation: cohabiting mothers reported considerably less adverse reaction to the birth than did non-cohabiting mothers. 4. Overall, mothers of ex-nuptial children had a fairly sophisticated appreciation of contraceptive methods. 5. One quarter of unplanned ex-nuptial pregnancies were the result of contraceptive failure and three-quarters were the result of contraceptive non-usage. 6. In common with previous findings for nuptial pregnancies, about 35 percent of unplanned ex-nuptial pregnancies were ascribed to a breakdown in the mother's pattern of usage of the contraceptive pill.
本文考察了在基督教堂儿童发展研究第一阶段所研究的210例非婚生育的背景情况。研究结果表明：1. 近一半的孩子是在同居情况下受孕的。2. 近五分之一的非婚生育孩子是计划内怀孕的结果。3. 母亲对生育和怀孕的反应因母亲的情况而异：同居母亲报告的对生育的不良反应比非同居母亲少得多。4. 总体而言，非婚生育孩子的母亲对避孕方法有相当深入的了解。5. 四分之一的意外非婚怀孕是避孕失败的结果，四分之三是未使用避孕措施的结果。6. 与之前关于婚内怀孕的研究结果相同，约35%的意外非婚怀孕归因于母亲服用避孕药模式的中断。
