The Effect of Comorbidity on Treatment Outcome in an ODD Sample European Association for Behavioral and Cognitive Therapies, Reykjavik, Iceland, September 2011 Maria G Fraire, M.S. Emily F. McWhinney, B.S. Thomas H. Ollendick, Ph.D.

 ODD, Anxiety, and Comorbidity  Dual Pathway Model  Treatment Approaches  Present Study  Implications and Future Directions 2

 Pattern of negativistic, hostile, and defiant behavior (APA, 2000)  Prevalence: 2.6% % in community samples and 28% - 65% in clinical samples (Boylan et al., 2007)  Can be distinguished from typical behavior as early as preschool (Loeber, Burke, & Pardini, 2008)  Increased risk for another psychiatric disorder, including conduct disorder, substance abuse and depression (Loeber et al., 2000) 3

 Excessive worries or fears (APA, 2000)  Prevalence rates for at least 1 anxiety disorder: 6-20% (Costello et al., 2004)  No significant gender differences in childhood, but adolescence shows an increase in anxiety for girls (Van Oort, Greaves- Lord, Verhulst, Ormel & Huizink, 2009)  Risk for another anxiety disorder, depression, and substance abuse (American Academy of Child and Adolescent Psychology, 2007) 4

 About 40% of those with ODD have comorbid anxiety (Drabick, Ollendick, & Bubier, 2010)  High risk for negative outcomes (Brunnekreef et al., 2007, Franco, Saavedra, & Silverman, 2007) ◦ peer relations ◦ poor academic performance ◦ information processing deficits  Directionality ◦ Anxiety or ODD? 5

 Multiple problem hypothesis ◦ Anxiety exacerbates ODD  Buffer hypothesis ◦ Anxiety mitigates ODD 6

Method  Children and families were thoroughly assessed  Families were randomized to either PMT or CPS  12 weekly sessions  One week post, six months, and one year follow-ups 7

Empirically supported and well established treatment (Brestan & Eyberg, 1998) Manualized with specified content (Barkley, 1997) Goal: Diminish negative behaviors through parent behavior management skills 8

Not yet empirically supported Focus on lagging skills in the child and unsolved problems in the family Goal: Diminish negative behaviors through collaborating on solutions to unsolved problems 9

1. Does anxiety comorbidity affect treatment outcome as measured by ADIS CSR and the DBDRS? 2. Is there a difference between PMT and CPS in relation to comorbidity and treatment outcome? 10

 H 1 : Presence of anxiety disorder will enhance treatment outcome ◦ Dual Pathway Model  H 2 : Children with comorbid anxiety will do better in the CPS condition than the PMT condition ◦ Emphasis on child regulation skills 11

 78 children with ODD from NIMH RCT (Ollendick & Greene, )  7 to 14 years old (m=9.62)  47 males (60.3 %) 31 females (39.7%)  53.8% with comorbid anxiety  41 (52.6%) in PMT  37 (47.4%) in CPS 12

Children with an anxiety disorder were significantly more likely to be diagnosis free post treatment, χ 2 = 5.333, p =.021.

 ODD CSR ratings significantly reduced for children with an anxiety disorder  Number of symptoms, as reported on the DBDRS, significantly reduced from pre to post treatment  While the Anxiety CSRs did reduce, the change was not significant 19

 Anxiety can contribute to ODD treatment in a positive way however  Anxiety does not change during an ODD treatment  Comorbid children would benefit from combined treatments 20
