A number of studies have attempted to explain obstetric difficulties on the basis of psychosocial conditions which exist during pregnancy. In addition, recent research in the field of life event stress has indicated that life experiences occurring prior to a pregnancy may influence pregnancy outcome. The present study examines the ability of life event stress as well as a variety of medical, social and psychological variables to predict complications of pregnancy. In contrast to previous small-sample research, the present study examines 782 subjects. Multivariate statistical techniques are employed to analyse the numerous variables measured. Results suggest that 'age at birth of first child', 'education level', 'menstrual history', 'attitudes to pregnancy' and 'age at menstruation' best predict obstetric difficulties. However, only a small percentage of the variance of pregnancy complication scores is explained by these factors.
许多研究试图基于孕期存在的心理社会状况来解释产科困难。此外，生活事件压力领域的最新研究表明，怀孕前发生的生活经历可能会影响妊娠结局。本研究考察了生活事件压力以及各种医学、社会和心理变量预测妊娠并发症的能力。与之前的小样本研究不同，本研究考察了782名受试者。采用多变量统计技术来分析所测量的众多变量。结果表明，“头胎生育年龄”、“教育水平”、“月经史”、“对怀孕的态度”和“初潮年龄”最能预测产科困难。然而，这些因素仅解释了妊娠并发症评分方差的一小部分。
