This study examined the impact of the Positive Behavioral Management Strategies (PBMS) online educational program on 624 participants in the southeastern region of the United States. The PBMS program incorporates established behavioral management principles with new research-based practices to promote healthy, positive relationships between adults and children while constructively managing and preventing problematic behavior. Additionally, the PBMS program helps parents and teachers to recognize the motivations behind misbehaviors and to avoid some common mistakes in child behavioral management. It also describes how to recognize and capitalize on "teachable moments," which are indispensable in the developmental process. A retrospective-pre-test-then-posttest design was used to reduce response shift bias when assessing knowledge and skill intervention outcomes for twenty-two behavioral management variables. The PBMS program was shown to be effective for increasing knowledge and skills related to managing misbehavior while reinforcing interpersonal relationships and fostering a sense of responsibility and capability within the child. Large changes in standardized mean effect size from before to after the intervention were documented for all twenty-two variables studied. The PBMS program showed positive outcomes to assist participants to increase their knowledge and skills in managing child behavior successfully. Implications for educators and practitioners are discussed.
