The results revealed that findings are becoming increasingly nuanced with variations in levels of evidence related to ages of the children and characteristics of the specific treatment .
In addition , we focused our critique on generalization of treatment effects across setting s and time and on sample diversity ( with regard to ethnicity and levels of parent education ) in relation to the population .
Children of parents with higher levels of education than average appear to be overrepresented in the literature .
The purpose of this research was to up date the series of articles on evidence -based treatment for children and adolescents with attention deficit/hyperactivity disorder that have appeared in this journal ( Evans , Owens & Bunford , 2014 ; Pelham & Fabiano , 2008 ; Pelham , Wheeler , & Chronis , 1998 ) .
Effectiveness of the Challenging Horizons After-School Program for young adolescents with ADHD.
There are no empirically supported psychosocial treatments for adolescents with attention-deficit hyperactivity disorder ( ADHD ) .  This study examined the treatment benefits of the Challenging Horizons Program ( CHP ) , a psychosocial treatment program design ed to address the impairment and symptoms associated with this disorder in young adolescents . In addition to evaluating social and academic functioning outcomes , two critical questions from previous studies pertaining to the timing , duration , and family involvement in treatment were addressed . Forty-nine students recruited in two cohorts were r and omly assigned to receive either the CHP or a  community care condition . Outcomes suggested that students who received the CHP  improved compared to students in the control condition on measures of symptoms and impairment . Implication s related to timing , duration , and family involvement are reported , as well as recommendations for future studies
