This study examined the effectiveness, integrity, and acceptability of Conjoint Behavioral Consultation (CBC) with families and teachers of Hispanic children at risk for development of behavior problems. CBC is a four-step problem-solving approach (problem identification, problem analysis, treatment implementation, and treatment evaluation) that systematically promotes the active participation of parents in collaboration with school personnel. Seven children in a Tulsa (Oklahoma) Head Start program were subjects in an evaluation of the CBC process. Challenges encountered were related to participant recruitment, effective communication, scheduling and keeping appointments, following the CBC format, and data collection. Results indicated acceptability of interventions by parents and teachers, acceptability of the CBC process, greater treatment integrity by teachers than parents, and positive ratings for intervention effectiveness by both teachers and parents. The study concluded that CBC provides a viable option in service delivery when addressing the needs of preschool children of Hispanic heritage but offers recommendations concerning the need to emphasize a success orientation, data collection techniques, and the interpreter's role.
