Parents play an important role in creating home language environments that promote language development. A nonequivalent group design was used to evaluate the effectiveness of a community-based implementation of LENA Start™, a parent-training program aimed at increasing the quantity of adult words (AWC) and conversational turns (CT). Parent-child dyads participated in LENA Start™ (n = 39) or a generic parent education program (n = 17). Overall, attendance and engagement in the LENA StartTM program were high: 72% of participants met criteria to graduate from the program. Within-subject gains were positive for LENA Start™ families. Comparison families declined on these measures. However, both effects were non-significant. Between-group analyses revealed small to medium-sized effects favoring LENA Start™ and these were significant for child vocalizations (CV) and CT but not AWC. These results provide preliminary evidence that programs like LENA StartTM can be embedded in community-based settings to promote quality parent-child language interactions.

促进早期语言发展的家长教育：LENA StartTM 的初步评估

父母在创造促进语言发展的家庭语言环境方面发挥着重要作用。使用非等效组设计来评估基于社区的 LENA Start™ 实施的有效性，LENA Start™ 是一项旨在增加成人词 (AWC) 和会话轮换 (CT) 数量的家长培训计划。亲子二人组参加了 LENA Start™ (n = 39) 或通用家长教育计划 (n = 17)。总体而言，LENA Start 的出勤率和参与度TM值计划很高：72％的参与者符合从该计划毕业的标准。LENA Start™ 家庭的受试者内收益是积极的。比较家庭在这些措施上有所下降。然而，这两种影响都不显着。组间分析显示有利于 LENA Start™ 的中小型效应，这些效应对儿童发声 (CV) 和 CT 意义重大，但对 AWC 不重要。这些结果提供了初步证据，证明像 LENA Start 这样的程序TM值可以嵌入基于社区的环境中，以促进高质量的亲子语言互动。
