Child parent dyadic treatment for anxiety disorders in youths

There is evidence for the efficacy of treatments for childhood anxiety disorders; however, less is known about whether including parents in the child\u27s treatment enhances child treatment response. There also are few studies that have examined predictors of treatment completion/non-completion and success/failure. In this dissertation, a child focused individual treatment was compared to a dyadic child-parent treatment. In dyadic, parent anxiety symptoms and child-parent relationships were targeted. Based on the Transfer of Control Model proposed by Silverman and Kurtines (1996a, b, 2005), it was hypothesized that treatment changes in parent anxiety symptoms and child-parent relationships would be related to positive child treatment response. Participants were 119 youths (ages 6 to 16 years, M = 9.93 SD = 2.75; 68 girls) and their parents. All youth were born in the U.S. but had various backgrounds; 40 were European American, 73 were Latinos/as, 6 were of other ethnic backgrounds or did not report their ethnicity. Participants signed informed consent (assent for youths) and completed a pretreatment assessment. Participants were randomized to a child individual treatment or dyadic treatment, were assessed immediately after treatment and one year post treatment. Findings showed that treated youths improved across all measures over time. Comparison of treatment conditions across all measures showed no statistically significant differences between the child individual and dyadic treatment. Reductions in parent anxiety symptoms and improvements in child-parent relationships were significantly related to child treatment change at posttreatment and at one year follow-up across treatments. No factors differentiated completers from non-completers and only parent reported child internalizing behavior problems were significantly negatively related to child treatment response. The study findings support a premise of the Transfer of Control Model that changes in parent anxiety symptoms and child-parent relationships are related to child treatment response. The study findings show that children can be successfully treated when parents are included as co-clients in dyadic treatment, thereby supporting the utility of this approach in practice
