Preschools provide a promising setting in which to conduct preventive interventions for childhood problems, but classroom programs can only be effective if teachers are willing and able to implement them. This study is one of the first to investigate predictors of the frequency of teacher participation in a classroom-based, randomized controlled trial of an integrated prevention program for preschoolers. The intervention was designed to promote school readiness with an integrated social and academic program, to be implemented by teachers with the support of classroom consultants. The current study is part of a larger project conducted with Head Start and community child care centers that serve primarily economically disadvantaged families; 49 teachers from 30 centers participated in this study. Overall, teachers conducted approximately 70% of the program activities. Participation decreased significantly over time from the first to the final week of the intervention, and also decreased within each week of the intervention, from the first to the final weekly activity. Teachers working at community child care centers implemented more intervention activities than did Head Start teachers. Teacher concerns about the intervention, assessed prior to training, predicted less participation. In addition, teachers' participation was positively related to their perception that their centers and directors were supportive, collegial, efficient, and fair, as well as their job satisfaction and commitment. Teacher experience, education, ethnicity, and self-efficacy were not significantly related to participation. In multi-level models that considered center as a level of analysis, substantial variance was accounted for by centers, pointing to the importance of considering center-level predictors in future research.
幼儿园为开展针对儿童问题的预防性干预提供了一个很有前景的环境,但只有教师愿意且有能力实施课堂项目时,这些项目才会有效。本研究是最早调查教师参与一项针对学龄前儿童的综合预防项目的课堂随机对照试验频率的预测因素的研究之一。该干预旨在通过一个综合的社会和学术项目促进入学准备,由教师在课堂顾问的支持下实施。当前的研究是与主要服务经济弱势家庭的“启智计划”和社区儿童保育中心合作开展的一个更大项目的一部分;来自30个中心的49名教师参与了本研究。总体而言,教师开展了大约70%的项目活动。从干预的第一周到最后一周,参与度随时间显著下降,而且在干预的每一周内,从第一次到最后一次每周活动,参与度也在下降。在社区儿童保育中心工作的教师比“启智计划”教师实施了更多的干预活动。在培训前评估的教师对干预的担忧预示着参与度较低。此外,教师的参与度与他们认为自己的中心和主任支持、合作、高效且公平的看法呈正相关,也与他们的工作满意度和投入度呈正相关。教师的经验、教育程度、种族和自我效能感与参与度没有显著关系。在将中心作为分析层面的多层次模型中,中心解释了相当大的方差,这表明在未来研究中考虑中心层面的预测因素很重要。
