Image Theses and Dissertations Improving treatment acceptability among teachers by increasing knowledge of ADHD. Teacher perceptions of proposed interventions play an important role in whether or not a teacher agrees to implement an intervention and does so with integrity. It is assumed that the acceptability of the treatment to the teacher is necessary, but not sufficient, for implementation of the intervention. As a consultant, it may be helpful to know what can be done in advance to increase the likelihood that teachers will find interventions acceptable. One factor that may improve acceptability is teacher knowledge, either of the interventions proposed or the child's disorder. View Item

Image Theses and Dissertations Intervening in dietary habits of African-American children: An impact evaluation of the Every Day, Lots of Ways Interdisciplinary Nutrition Education Curriculum. Lifelong dietary habits begin in childhood. Efforts to impact eating patterns, therefore, should be directed at young children. The school environment is ideal for teaching young children about improving healthy eating habits because large numbers of students can be targeted in a cost effective manner, and instruction is a natural part of the school day. Previous literature in the area of prevention and health promotion indicates that the provision of information alone does not effectuate positive behavioral change. View Item
