The general development of 40 deaf and hard of hearing infants was analyzed. The infants were placed into one of two groups according to age at which hearing loss was identified: (a) before age 6 months and (b) after age 18 months. The mean age at testing was 40 months. Developmental quotients (DQs) were used to compare results regardless of the infants' age at time of testing. Infants were evaluated on the basis of their DQ scores on the Minnesota Child Development Inventory (MCDI; Ireton & Thwing, 1972). MCDI subtests include general development, gross motor, fine-motor, expressive language, comprehension-conceptual, situation-comprehension, self-help, and personal-social. Infants whose hearing loss was identified before age 6 months scored significantly higher than those whose hearing loss was identified after age 18 months in the expressive language and comprehension-conceptual subtests. The performance of the earlier-identified group supports the earliest identification of hearing loss and encourages implementation of universal hearing screening.
对40名失聪和听力有障碍的婴儿的总体发育情况进行了分析。这些婴儿根据听力丧失被确诊的年龄被分为两组：（a）6个月之前和（b）18个月之后。测试时的平均年龄为40个月。使用发育商数（DQ）来比较结果，而不考虑测试时婴儿的年龄。根据婴儿在明尼苏达儿童发育量表（MCDI；艾雷顿和特温，1972年）上的DQ分数对他们进行评估。MCDI子测试包括总体发育、大运动、精细运动、表达性语言、理解概念、情境理解、自理和个人社交。在表达性语言和理解概念子测试中，6个月之前被确诊听力丧失的婴儿得分显著高于18个月之后被确诊听力丧失的婴儿。较早确诊组的表现支持尽早确诊听力丧失，并鼓励实施普遍听力筛查。
