Medical records, personal interviews about the childbirth experience, and self-administered attitudinal and socioeconomic data were obtained 1 to 3 days post partum in a large metropolitan hospital, for 249 women, 95 of whom had taken psychoprophylaxis training for childbirth prior to delivery. When controlled by parity, psychoprophylactic preparation was not related to any obstetric differences except for lower levels of anesthesia for both primiparas and multiparas and lower levels of analgesia among multiparas only. Preparation was significantly related to lower levels of pain and higher levels of enjoyment during childbirth, and these psychological benefits did not diminish when controlled for parity, socioeconomic status, and four sets of psychological and attitudinal characteristics.
在一家大型都市医院，于产后1至3天收集了249名妇女的病历、关于分娩经历的个人访谈以及自行填写的态度和社会经济数据，其中95名妇女在分娩前接受了分娩心理预防训练。在按产次进行对照时，心理预防准备与任何产科差异均无关联，但初产妇和经产妇的麻醉水平较低，且仅经产妇的镇痛水平较低。准备工作与分娩期间较低的疼痛水平和较高的愉悦水平显著相关，并且在对产次、社会经济地位以及四组心理和态度特征进行对照时，这些心理益处并未减弱。
