Designed and tested a home-based intervention program for low-income mothers with toddler and at least one other child under five. Sex of toddlers and race (black or white) about equally divided. Nine months of weekly home visits were specifically planned for each mother to enhance her effectiveness as an educational change agent. Treatment was planned to promote skills and understandings applicable over range of ages. Pretests, immediate posttests, and posttests one and two years later were administered to 27 experimental families and to a randomly assigned control group of 20. At .05 level of significance or beyond, experimentals excelled controls on receptive language test (toddler), on the Caldwell HOME (mother was indirectly rated as an educational change agent), and on a measure of teaching style (mother). They were also significantly superior on the Binet (toddler) at second posttest. No differences found with older siblings on Slosson Intelligence Test. Differences at third posttest were at least as great as earlier ones on mother measures. Relationships among child and mother measures are discussed.
为有蹒跚学步儿童且至少还有一个五岁以下其他孩子的低收入母亲设计并测试了一个家庭干预项目。蹒跚学步儿童的性别和种族(黑人或白人)大致平均分布。为每位母亲专门安排了为期九个月的每周一次家访,以提高她作为教育变革推动者的效能。计划通过治疗来提升适用于不同年龄段的技能和认知。对27个实验家庭以及随机分配的20个对照组家庭进行了前测、即时后测以及一年和两年后的后测。在0.05显著水平及以上,实验组在接受性语言测试(针对蹒跚学步儿童)、考德威尔家庭环境量表(母亲被间接评定为教育变革推动者)以及一种教学风格测评(针对母亲)方面优于对照组。在第二次后测时,实验组在比奈智力量表(针对蹒跚学步儿童)上也显著更优。在斯洛森智力测试中,未发现实验组与年长兄弟姐妹之间存在差异。在第三次后测时,母亲测评方面的差异至少与早期一样大。文中讨论了儿童与母亲测评之间的关系。
