I examined the role of children's or teacher's effortful control (EC) in children's academic functioning in early elementary school in two separate studies. In Study 1, I tested longitudinal relations between parents' reactions to children's displays of negative emotions in kindergarten, children's EC in first grade, and children's reading or math achievement in second grade (N = 291). In the fall of each school year, parents reported their positive or negative reactions and parents and teachers reported on children's EC. Standardized achievement tests assessed achievement each spring. Results from autoregressive panel mediation models demonstrated that constructs exhibited consistency across study years. In addition, first-grade EC mediated relations between parents' reactions (i.e., a difference composite of positive minus negative reactions) at kindergarten and second-grade math, but not reading, achievement. Findings suggest that one method of promoting math achievement in early school is through the socialization of children's EC. In Study 2, I examined relations between teachers' EC, teachers' reactions to children's negative emotions, the student-teacher relationship (STR), and children's externalizing behaviors or achievement among 289 second-graders and their 116 teachers. Results from mixed-model regressions showed that negative reactions and teacher-reported STR mediated relations between teachers' EC and math achievement. In addition, teacher-reported STR mediated links between teachers' EC and externalizing problems across reporters and between teachers' EC and reading achievement. Tests of moderated mediation indicated that a high-quality STR was negatively associated with externalizing problems and high levels of teachers' negative reactions were negatively related to math achievement only for students low in EC. In tests of moderation by social competence, teachers' reports of high-quality STRs tended to be negatively associated with externalizing problems, but relations were strongest for students not high in social competence. For students low in social competence only, children's reports of a high-quality STR was related to lower reading achievement. These results highlight the utility of considering whether and how teachers' own intrinsic characteristics influence classroom dynamics and students' academic functioning outcomes.

Children removed from methamphetamine laboratories are a severely understudied population despite the widespread deprivation parental methamphetamine abuse has on children, particularly in homes where methamphetamine is produced. Arizona's children are uniquely affected by the use and manufacturing of methamphetamine due to the geographic location and landscape of the state. A sample of 144 children removed from their homes during the seizure of methamphetamine laboratories, as part of the Arizona Drug Endangered Children program between 1999 and 2003, was investigated. Results indicate that younger children were more likely to be reported by Child Protective Services as high or moderate risk of further abuse, test positive for methamphetamine, and have maternal alleged perpetrators of abuse. Older children were more likely to be reported as low risk for further abuse, test negative for methamphetamine, and have paternal alleged perpetrators of abuse. Results also show that children initially placed in foster care were more likely to remain in foster care at the final assessment than to be living with a parent or kin. These findings have implications for individuals working with children removed from methamphetamine laboratories, including Child Protective Services case workers, medical personnel, temporary and permanent child caregivers (i.e., foster care, kin care, adoptive parents, and shelters), and community members (i.e., teachers). Recommendations based on study findings are offered to child and family advocates and interventionists.
