This study investigated the effectiveness of conjoint behavioral consultation (CBC) for addressing externalizing behavior concerns in African American children at home and school in a lowsocioeconomic status (SES), urban setting. A small-n, multiplebaseline design was employed across participants. Three of the six caregivers were unable to follow through with the consultation process, constituting a 50% completion rate. The three remaining caregivers implemented the empirically supported interventions with moderate integrity. Caregiver and teacher ratings showed that the procedural acceptability of CBC was high throughout the consultation process. The classroom teachers consistently found the behavioral interventions highly acceptable; however, the caregivers' perceptions of the interventions initially were less favorable and improved as the interventions progressed. Clinically significant gains were observed across settings for all children. Consultants should be prepared to modify consultation and intervention procedures to enhance social validity, integrity, and effectiveness with caregivers of low-SES.Approximately 14% to 20% of the children in the general population exhibit challenging behaviors in the home or school setting (Brandenburg, Friedman, & Silver, 1990;Reichle et al., 1996). Although children's oppositional and aggressive behaviors typically decrease after 2 years of age, a Correspondence should be sent to Tammi J. Ohmstede, PhD, NCSP,
