This study sought to assess the association between early developmental assessment of toddlers with idiopathic global developmental delay (GDD) and their later intelligence test scores.
Toddlers with idiopathic GDD attending a community clinic over a 6-year period were assessed initially using the Griffiths Mental Development Scales - Extended Revised version (GMDS-ER) and later completing formal intelligence testing using the Stanford-Binet Intelligence Scale - 5th Edition (SB5) at age 4-6 years. Spearman's correlation was used to assess the association of quotient scores across the tools. The composite quotient (GQ) and the subscale quotients of GMDS-ER were correlated with the full-scale IQ (FSIQ), verbal and non-verbal IQ scores from the SB5.
Thirty of 153 children assessed at the clinic were eligible for the study. The correlation between GMDS-ER GQ and later SB5 FSIQ was strong (r = 0.86, P < 0.001). The subscales' associations were moderate to strong (0.48-0.71). Eighty-six percent (86%) of children with delay on GMDS-ER GQ were found later to be in the impaired category based on the FSIQ of the SB5.
There was a strong association between toddlers' early developmental quotients and later IQ scores for children with idiopathic GDD, though agreement between early GDD diagnoses and later intellectual disability is not absolute. Individualised care is needed around prognostic advice and recommendations to caregivers and families in the early years, so they may effectively plan for interventions, supports and later reassessment to optimise their child's development and learning.
本研究旨在评估患有特发性全面发育迟缓（GDD）的幼儿早期发育评估与其后期智力测试分数之间的关联。
在6年期间到社区诊所就诊的患有特发性GDD的幼儿最初使用格里菲斯心理发展量表 - 扩展修订版（GMDS - ER）进行评估，随后在4至6岁时使用斯坦福 - 比奈智力量表 - 第5版（SB5）完成正式智力测试。使用斯皮尔曼相关性来评估各工具商数分数之间的关联。GMDS - ER的综合商数（GQ）和子量表商数与SB5的全量表智商（FSIQ）、言语和非言语智商分数相关。
在诊所评估的153名儿童中有30名符合研究条件。GMDS - ER GQ与后期SB5 FSIQ之间的相关性很强（r = 0.86，P < 0.001）。子量表的关联为中度至强（0.48 - 0.71）。根据SB5的FSIQ，发现GMDS - ER GQ延迟的儿童中有86%后来属于受损类别。
对于患有特发性GDD的儿童，幼儿早期发育商数与后期智商分数之间存在很强的关联，尽管早期GDD诊断与后期智力残疾之间的一致性并非绝对。在早期需要围绕向照顾者和家庭提供预后建议和推荐进行个性化护理，以便他们可以有效地规划干预措施、支持和后期重新评估，以优化孩子的发育和学习。
