OBJECTIVE
To assess the relationship between word identification and intelligence in adults with mild mental retardation (IQ < 80).
METHOD
A standardized evaluation was administered to 67 adults with mild mental retardation. The evaluation included a psychiatric interview, the WAIS-R, and a 2-h interview with a speech therapist and reading tests.
RESULTS
Causes of mental retardation were diverse in the sample, and IQ scores ranged from 43 to 79 (mean score = 64). All subjects exhibited reading impairment, including 69% with severe impairment. No subject with an IQ score under 65 was able to perform adequately in the word identification tasks. Word identification was correlated with total and verbal IQ, but not with performance IQ.
CONCLUSION
Our results suggest that, in contrast to subjects with normal intelligence, IQ score is correlated with reading in subjects with mild mental retardation. Finally, remediation should be preferentially implemented for subjects with IQ score greater than 65.
目的
评估轻度智力障碍（智商<80）成人的单词识别能力与智力之间的关系。
方法
对67名轻度智力障碍成人进行了标准化评估。评估包括精神病学访谈、韦氏成人智力量表修订版（WAIS-R），以及与言语治疗师进行的2小时访谈和阅读测试。
结果
样本中智力障碍的病因多种多样，智商分数在43至79之间（平均分数=64）。所有受试者均表现出阅读障碍，其中69%为严重障碍。智商分数低于65的受试者在单词识别任务中均无法充分完成。单词识别与总智商和言语智商相关，但与操作智商无关。
结论
我们的结果表明，与智力正常的受试者不同，轻度智力障碍受试者的智商分数与阅读能力相关。最后，应优先对智商分数大于65的受试者实施补救措施。
