Relationship between IQ, DQ and SQ in young children with hearing impairment

The data was collected from 40 young children with hearing impairment (YCHI) and their caregivers at the Department of Clinical Psychology, in a Government teaching Institute of Speech and Hearing. These 40 YCHI underwent the SFBT, the GDT, the DST, and the VSMS. YCHI were referred for assessment of intelligence prior to cochlear implant surgery. Assent from the caregivers of the participants was taken.
A positive correlation was found between the GDT IQ and the SQ (r= 0.558, p < 0.01), the GDT IQ and the DQ (r= 0.431, p < 0.01), the SQ and the DQ (r=0.576, p< 0.01). On comparing the means of the SFBT IQ, the GDT IQ, the DQ and the SQ, the mean of the SFBT IQ was the highest and the mean of the DQ was the lowest. The DQ was 35 and 31 points lesser than the SFBT IQ and the SQ respectively. SFBT IQ score was higher (3 points) than the SQ.

本数据集采集自某公立言语听力教学研究院临床心理学系，受试对象为40名听力障碍幼儿（Young Children with Hearing Impairment, YCHI）及其照料者。所有受试幼儿均在人工耳蜗植入手术前接受智力评估，并完成了SFBT、GDT、DST及VSMS四项测评。本研究已获取所有受试幼儿照料者的知情同意。
研究发现，GDT智商与SQ呈显著正相关（r=0.558, p<0.01），GDT智商与DQ呈显著正相关（r=0.431, p<0.01），SQ与DQ亦呈显著正相关（r=0.576, p<0.01）。对SFBT智商、GDT智商、DQ及SQ的均值进行比较后可知，SFBT智商的均值为所有指标中最高，DQ的均值则最低。DQ的均值分别较SFBT智商与SQ低35分与31分，SFBT智商得分较SQ高出3分。
