This study reports the results of a randomized controlled trial examining the effect of Conjoint Behavioral Consultation (CBC), a family-school partnership intervention, on children's behaviors, parents' skills, and parent-teacher relationships in rural community and town settings. Participants were 267 children, 267 parents, and 152 teachers in 45 Midwestern schools. Using an Intent to Treat approach and data analyzed within a multilevel modeling framework, CBC yielded promising results for some but not all outcomes. Specifically, children participating in CBC experienced decreases in daily reports of aggressiveness, noncompliance, and temper tantrums; and increases in parent-reported adaptive skills and social skills at a significantly greater pace than those in a control group. Other outcomes (e.g., parent reports of internalizing and externalizing behaviors) suggested a nonsignificant effect at post-test. CBC parents reported using more effective parenting strategies, gaining more competence in their problem-solving practices, and feeling more efficacious for helping their child succeed in school than parents in the control group. Parents participating in CBC also reported significant improvements in the parent-teacher relationship, and the parent-teacher relationship mediated the effect of CBC on children's adaptive skills. Implications for practice in rural communities, study limitations, and directions for future research are discussed. [This article was published in "Journal of School Psychology" v62 p81-101 2017.]
