IQ change in association with change of environment occurred in a sample of 34 patients with a diagnosis of abuse dwarfism. Low and persistent impairment of IQ was associated with abuse. By contrast, IQ elevation was associated with rescue. Multiple regression analysis revealed that duration of rescue was the primary variable associated with IQ elevation; age and IQ level at rescue were secondary. IQ elevation was gradual and progressive over the years, as rescue was maintained. In abuse, the mean IQ was 66 (range, 36-101), and after rescue it was 90 (range 48-133). The greatest magnitude of change, from IQ 36 to 120, was in a girl between the ages of 3 yr 8 months and 13 yr 11 months.
在34例被诊断为虐待性侏儒症的患者样本中，智商变化与环境变化相关。智商的持续低下与虐待有关。相比之下，智商升高与获救有关。多元回归分析显示，获救持续时间是与智商升高相关的主要变量；获救时的年龄和智商水平是次要变量。随着获救状态的持续，智商升高在数年中呈渐进性。受虐待时，平均智商为66（范围36 - 101），获救后为90（范围48 - 133）。智商变化幅度最大的是一名年龄在3岁8个月至13岁11个月之间的女孩，从智商36升至120。
