Enhanced Cognitive-Behavioral Treatment for Anxiety Disorders in Children of Clinically Anxious Parents: Two Case Studies

Children with anxiety disorders are significantly less likely to recover following cognitive-behavioral therapy (CBT) if they have a parent with clinical anxiety. Despite this, prior research which has adapted CBT treatments to cater for this vulnerable clinical cohort of children is limited. In response to the identified need to optimize treatment outcomes for this particular group of children with anxiety disorders, an enhanced CBT intervention was recently developed, specifically to target anxiety maintenance factors in clinically anxious child–parent dyads. This dual case study presents the implementation of the enhanced intervention with two children with complex clinical presentations. Prior to treatment, both children met criteria for multiple anxiety disorders, as did their mothers. The presented case studies describe session-by-session treatment accounts, with a particular focus on the children’s experiences of individual and joint-observational exposure treatment components. Outcome data is provided for both children and their mothers, based on assessment measures collected at pre- and post-treatment, and during the intervention. At post-treatment, both children demonstrated symptom reduction and improved functioning across all diagnoses, including remission on a secondary diagnosis, although both still met criteria for their primary diagnoses. Additionally, self-reported outcomes on intervention acceptability measures were favorable. Results implied that the enhanced intervention provided a viable alternative treatment approach for children and their parents with co-occurring anxiety disorders. Recommendations are provided for clinicians delivering CBT to clinically anxious child–parent dyads.

Intermittent Motivational Interviewing and Transdiagnostic CBT for Anxiety: A Randomized Controlled Trial

Recent meta-analytic findings suggest that Motivational Interviewing (MI) used as an adjunct to Cognitive Behavior Therapy (CBT) for anxiety disorders improves overall treatment outcomes (Marker & Norton, 2018). However, when used as a prelude to CBT, MI significantly increases the length of treatment and numerous studies note that the effectiveness of pre-treatment MI subsides over time. The current study adapted an already established 12-session transdiagnostic CBT protocol (tCBT, Norton, 2012) to include one hour of MI spread across four sessions of tCBT (sessions 1, 3, 8, and 10) at 15 minutes each, with the option of including additional MI if resistance arose in therapy. Thirty-six treatment seeking adults with principal anxiety disorder diagnosis were randomly assigned to receive intermittent MI and tCBT (iMI + tCBT) or tCBT and psychoeducation. Results indicated that the iMI + tCBT condition significantly outperformed the tCBT condition on several primary outcome variables. While no significant difference was found between the two groups on clinician rated scores of participant principal anxiety disorder, differences were found on a composite index of participants' self-report measures of symptom improvement, and on clinician rated scores of global psychiatric functioning. These effects were not moderated by baseline motivation or baseline ambivalence. The study also found that the iMI + tCBT condition showed significantly greater improvement to comorbid conditions and greater reduction in self-report depressive symptoms. The inclusion of MI did not impact participant drop out. This study provides further support for integrating MI and tCBT and highlights that even small doses of MI can improve treatment outcomes, without increasing length of usual therapy. Limitations and future research options are also discussed.
