Attachment theory, developed by child psychiatrist John Bowlby, is considered a major theory in developmental psychology. Attachment theory can be seen as resulting from Bowlby's personal experiences, his psychoanalytic education, his subsequent study of ethology, and societal developments during the 1930s and 1940s. One of those developments was the outbreak of World War II and its effects on children's psychological wellbeing. In 1950, Bowlby was appointed WHO consultant to study the needs of children who were orphaned or separated from their families for other reasons and needed care in foster homes or institutions. The resulting report is generally considered a landmark publication in psychology, although it subsequently met with methodological criticism. In this paper, by reconstructing Bowlby's visit to several European countries, on the basis of notebooks and letters, the authors shed light on the background of this report and the way Bowlby used or neglected the findings he gathered.

四个国家的故事：鲍比（Bowlby）如何利用他的欧洲之行撰写世卫组织的报告并传播他的想法。

儿童精神病学家约翰·鲍比（John Bowlby）提出的依恋理论被认为是发展心理学的主要理论。依恋理论可以看作是鲍比的个人经历，他的心理分析教育，其后的行为学研究以及1930年代和1940年代社会发展的结果。这些事态发展之一就是第二次世界大战的爆发及其对儿童心理健康的影响。1950年，鲍比被任命为世界卫生组织顾问，研究因其他原因孤儿或与家人失散并需要在寄养家庭或机构中照料的儿童的需求。最终的报告虽然后来遭到方法论的批评，但通常被认为是心理学界具有里程碑意义的出版物。在本文中，通过重构鲍比对欧洲几个国家的访问，
