Abstract

The current study is a quantitative program evaluation of the effectiveness private practice for treating obsessive compulsive disorder while incorporating multiple validated components to reduce common barriers of treatment access. There were three outcomes used to evaluate the first being the reduction in symptom severity across treatment, the second being the length of time in treatment before reduction can be seen, and the third being the rates completing treatment as agreed by therapist and participant. The current study was able to complete analysis for the first and third research question, and unable to answer the second. The first and primary finding of the study is that the reduction of YBOCS scores across treatment is significant and achieved a very large effect size of d = 1.173. Participants in treatment were able to achieve significant reduction in the symptom severity of OCD as measured by the YBOCS and achieved a treatment response. Unfortunately, the second research question was not able to be answered due to the amount of missing data across the various timepoints. The third finding of this study is that 50% of the sample left treatment before agreement between therapist and client which is higher than the 20% treatment dropout rate suggested by the literature. Implications, limitations, and suggestions for future research are also discussed.
