Responses of 108 women in the first 5 months of pregnancy were compared to those given by expectant fathers, nonpregnant women, and nonexpectant men on two measures: a 55-item symptom checklist and the Beck Depression Inventory. Responses to the symptom checklist were factor analyzed to produce six factors accounting for 40.5% of the total variance. On only two of the six factors was there a significant tendency for the pregnant women to score higher than the other three groups: the factors labeled "Feeling ill" and "Feeling overweight." No significant impact of pregnancy was noted on the Beck Depression Inventory scores. It was concluded that a small group of reported physical symptoms but no common core of emotional symptoms characterizes the experience of early pregnancy.
研究比较了108名处于妊娠前5个月的女性与准父亲、未怀孕女性及非准父亲在两项测评中的反应：一份包含55个条目的症状清单以及贝克抑郁量表。对症状清单的反应进行了因子分析，得出六个因子，它们占总方差的40.5%。在这六个因子中，只有两个因子显示出孕妇得分显著高于其他三组的趋势，即标记为“感觉不适”和“感觉超重”的因子。在贝克抑郁量表得分上未发现妊娠有显著影响。研究得出结论，一小部分报告的身体症状但没有共同的情绪症状核心是早期妊娠体验的特征。
