This study investigated the influence of maternal and child variables on the maternal responsivity of 55 mothers with young children with fragile X syndrome. Data included video observations of mother-child interactions in four different contexts, standardized assessments with the children, and standardized questionnaires for the mothers. The video observations were coded for child communication acts; maternal responsivity was coded at two levels: a more general measure and a behavior-by-behavior measure. Results indicated that child developmental level and language ability strongly influenced behavior-by-behavior responsivity, while maternal IQ was the strongest predictor of both general and behavior-by-behavior responsivity, after controlling for child developmental level.
本研究调查了母婴变量对 55 名患有脆性 X 综合征的幼儿母亲反应性的影响。数据包括在四个不同情境下对母婴互动的视频观察、对儿童的标准化评估以及对母亲的标准化问卷。视频观察对儿童的沟通行为进行了编码；母亲的反应性在两个水平上进行了编码：更一般的测量和行为的逐个测量。结果表明，在控制儿童发育水平后，儿童的发育水平和语言能力强烈影响行为逐个反应性，而母亲的智商是一般和行为逐个反应性的最强预测因素。
