Significant differences in handedness patterns between groups of psychiatric patients and normal controls were identified in two recent British studies, with substantial disagreement in some important findings. Most of the discrepancies were attributable to the different application of a simple classification of handedness data, and the remainder to differences in sample size. Diagnosis, sex and age were then found to have a similar effect on handedness in both studies. Neurotic patients were similar to controls regardless of classification, whereas mixed handedness in personality disorder depended on it. There was no overall excess of left-handedness among schizophrenics, but trends towards excess sinistrality in men and fully dextrality in women approached significance.
最近两项英国研究发现，精神病患者组与正常对照组在利手模式上存在显著差异，但在一些重要发现上存在很大分歧。大多数差异归因于利手数据简单分类的不同应用，其余差异则归因于样本量的不同。然后发现，在两项研究中，诊断、性别和年龄对利手的影响相似。无论分类如何，神经症患者与对照组相似，而人格障碍中的混合利手则取决于分类。精神分裂症患者中左利手并没有总体上的过多情况，但男性左利手过多和女性完全右利手的趋势接近显著水平。
