This paper presents the case of a 29 year old woman who compulsively ate rocks and pebbles, a habit developed in childhood. Extensive psychometric testing did not demonstrate phobias, obsessions, tendency to increased anxiety, depression or anorexic or bulimic disorder. The development of pica is partially explained by a childhood eating disorder, obsessive personality traits, cultural factors and specific (personality induced) stresses. Stress-reducing measures were successful in eliminating the eating disorder.
本文介绍了一名29岁女性的病例，她强迫性地吞食石头和鹅卵石，这种习惯始于童年。广泛的心理测试未显示出恐惧症、强迫症、焦虑增加倾向、抑郁症或厌食症或贪食症。异食癖的形成部分可归因于童年饮食失调、强迫型人格特质、文化因素和特定（人格诱发的）压力。减压措施成功消除了饮食失调。
