Teaching and Research Interests

Research Interests

Broadly defined, Dr. Erchul's major research interest is psychological consultation. Consultation within school psychology typically involves the delivery of psychoeducational services to child and adolescent clients through a staff member such as a classroom teacher. For example, a school psychologist may consult with a teacher about solving problems that involve a student or group of students. The successful practice of psychological consultation in schools has clear implications for preventing academic failure, promoting mental health, and providing a support system to staff members. Consultation is integral to contemporary methods of service delivery in schools, such as those found in problem-solving teams and response to intervention.

Dr. Erchul primarily has examined interpersonal dynamics and participant outcomes associated with the practice of behavioral consultation, conjoint behavioral consultation, mental health consultation, and prereferral intervention teams in schools. One strand of this research has involved the coding of audiotapes and transcripts of dyadic and small group interviews in order to link verbal process/interaction measures to various outcome measures. Another strand has used a survey methodology to study the interpersonal dynamics of school consultation with respect to social influence as revealed through social power bases/influence strategies. This approach allows a glimpse into how one participant may influence another participant during consultation, such as how a teacher’s implementation fidelity of an intervention may be maintained or strengthened. A third, more recent line of research has studied the use of technology (e.g., videoconferencing, telepresence robotics) within school-based consultation.
