Show moreDisruptive behavior disorders (DBDs) are among the most common and challenging diagnoses in children. It is well documented that family therapy services can provide effective treatment for DBDs, but therapy dropout rates are high. This leaves many children untreated, particularly in urban settings. Literature supports relationships between several variables and premature termination of therapy services, including child gender, child psychopathology, parent psychopathology, and perceived barriers to treatment participation. The current study aimed explore if combinations of parent and child psychopathology and their relationship related to therapy completion. Multiple imputation was utilized due to the presence of several missing data points. Results indicated that combinations did not significantly predict therapy completion. Implications of the research, limitations, and suggestions for future research are discussed. Ph.D. in Clinical Psychology, May 2012 Show less
