This longitudinal study examined a comprehensive set of predictors of preschool language performance in a sample of children of adolescent mothers. Six domains of risk (low maternal verbal ability, intergenerational risk, contextual risk, relational risk, home environmental risk, and child characteristics) for poor preschool language development, measured throughout early childhood, were examined in a sample of 154 children born to adolescent mothers. Logistic regression revealed that having a poor language-learning home environment was associated with children's low language scores even after accounting for mothers' below-average verbal ability. More importantly, however, was the exploration of the 'dual risk' hypothesis that evaluated the effects of combined risk factors. Being reared by a mother with low verbal ability amplified the risk of a poor quality home linguistic environment, whereas having a poor home linguistic environment did not adversely affect the language development of children with mothers of average verbal ability. Implications for intervention are discussed with regard to specificity of intervention efforts within subpopulations of risk identified in this paper.
这项纵向研究在青少年母亲的子女样本中,考察了一系列全面的学前语言表现预测因素。在154名青少年母亲所生子女的样本中,研究了在整个幼儿期测量的学前语言发展不良的六个风险领域(母亲语言能力低、代际风险、情境风险、关系风险、家庭环境风险和儿童特征)。逻辑回归分析表明,即使在考虑了母亲低于平均水平的语言能力之后,处于不利于语言学习的家庭环境仍与儿童的低语言分数相关。然而,更重要的是对“双重风险”假说的探索,该假说评估了综合风险因素的影响。由语言能力低的母亲抚养会加大家庭语言环境质量差的风险,而家庭语言环境差并不会对母亲语言能力中等的孩子的语言发展产生不利影响。本文针对所确定的风险亚群体内干预措施的特异性,讨论了干预的意义。
