偷窃癖是一种精神疾病,现实生活中不常见,文学作品里更是罕见,对其科学研究也远远不足。研究认为,偷窃癖多与患者的童年创伤有关,其治疗复杂,且易复发。美国心理学家认为,近二十年的医学实践证明,“接纳与承诺疗法”对精神创伤及相关精神疾病疗效显著。此疗法观照下的三重自我理论,为2011年普利策小说奖作品《恶棍来访》中的萨莎形象提供了一个有益的阐释视角。 Stealing is a mental illness, uncommon in real life, rare in literary works, and far from scientific research. Research suggests that stealing is associated with childhood trauma to patients and its treatment is complex and prone to relapse. According to American psychologists, nearly two decades of medical practice have proved that “Admit and Promise therapies ” have significant effects on trauma and related mental disorders. The Triple Self Theory under this therapy provides a useful interpretation of Sasha’s image in the 2011 “The Villain Invasion” by the Pulitzer Prize Novel.
