To further understand psychopathy within a Developmental and Life-Course Criminology perspective, the current article investigates the stability and change in psychopathy from childhood to middle age. The Cambridge Study in delinquent development is a prospective longitudinal study of 411 males, where psychopathy was coded based on contemporanously collected data from young people and in adulthood. Psychopathy in middle age was assessed in a medical interview. The findings indicate a high degree of stability of psychopathy across the life-course. To explain stability and change, childhood factors that might predict this were investigated. Few factors were related to stability and change across the life-course. Poor supervision, poor housing, a large family, and having a convicted father were associated with any change. A depressed mother was associated with a later decrease in psychopathy. This investigation has implications not only for the downward extension of psychopathy to childhood, but also for the understanding of the development of criminal and antisocial behavior.

前瞻性纵向研究中精神病的稳定性：剑桥研究在不良发展中的结果

为了从发展和生命历程犯罪学的角度进一步了解精神病，本文调查了从儿童到中年精神病的稳定性和变化。剑桥犯罪发展研究是一项对 411 名男性的前瞻性纵向研究，其中精神病是根据同时期从年轻人和成年期收集的数据进行编码的。在医学访谈中评估了中年精神病。研究结果表明，精神病态在整个生命过程中具有高度的稳定性。为了解释稳定性和变化，调查了可能预测这一点的童年因素。很少有因素与整个生命过程中的稳定性和变化有关。监管不力、住房条件差、家庭大、父亲被定罪与任何改变。一位抑郁的母亲与后来的精神病减少有关。这项调查不仅对精神病向下延伸到儿童期具有影响，而且对理解犯罪和反社会行为的发展也有影响。
