Comorbidity , gender , age , number of sessions , duration , intervention type , setting , medication use or dropout percentage did not influence the effect of treatment .
CONCLUSIONS Psychological treatments have a small effect in reducing parent- , teacher- and observer-rated CD problems  in children and adolescents with clinical CD problems/diagnosis .
There is not enough evidence to support one specific psychological treatment over another .
Many reports failed to provide detailed information to allow optimization of psychological treatment strategies
BACKGROUND This meta- analysis evaluates the efficacy of nonpharmacological treatments for conduct disorder ( CD ) problems in children and adolescents , based on child , parent and teacher report .
Evaluation of a Booster Intervention Three Years After Acute Treatment for Early-Onset Disruptive Behavior Disorders
This study examines the impact of a brief booster treatment administered 3 years after the delivery of an acute treatment in a group ( n = 118 ) of clinical ly referred boys and girls ( ages 6 to 11 ) originally diagnosed with Oppositional Defiant Disorder ( ODD ) or Conduct Disorder ( CD ) . At the conclusion of the acute treatment and three-year follow-up period ( i.e. , study month 42 ) , the sample was re-r and omized into Booster treatment or Enhanced Usual Care and then assessed at four later timepoints ( i.e. , post-booster , and 6- , 12- and 24-month booster follow-up ) . Booster treatment was directed towards addressing individualized problems and some unique developmental issues of adolescence based on the same original protocol content and treatment setting , whereas the Enhanced Usual Care condition involved providing clinical recommendations based on the assessment and an outside referral for services . HLM analyses identified no significant group differences and few time effects across child , parent , and teacher reports on a broad range of child functioning and impairment outcomes . Analyses examining the role of putative moderators or predictors ( e.g. , severity of externalizing behavior , dose of treatment ) were likewise non-significant . We discuss the nature and implication s of these novel findings regarding the role and timing of booster treatment to address the continuity of DBD over time
