Mediators of Treatment Effects in a Randomized Clinical Trial of Multisystemic Therapy-Health Care in Adolescents With Poorly Controlled Asthma: Disease Knowledge and Device Use Skills.OBJECTIVE
 Determine whether Multisystemic Therapy-Health Care (MST-HC) improved asthma knowledge and controller device use skills among African-American youth with poorly controlled asthma and whether any improvements mediated changes in illness management.



Multisystemic Therapy-Health Care
Determine whether Multisystemic Therapy-Health Care (MST-HC) improved asthma knowledge and controller device use skills among African-American youth with poorly controlled asthma and whether any improvements mediated changes in illness management.


 Families were randomized to MST-HC or attention control.  In linear mixed models, adolescents in the MST-HC group had increases in asthma knowledge; asthma knowledge was unchanged for attention control.  Controller device use skills increased for adolescents in the MST-HC group, while skills declined for attention control.
