This mixed method study examined factors associated with parents not attending their child's mental health treatment after initially seeking help for their 2-5 year old child. It was part of a larger study comparing two evidence-based treatments among low-income racial/ethnic minority families seeking child mental health services. Of 123 parents who initiated mental health treatment (71% African American or multi-racial; 97.6% low-income), 36 (29.3%) never attended their child's first treatment session.
