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

A transdiagnostic meta-analysis of acute augmentations to psychological therapy

At least half of all patients with mental health disorders do not respond adequately to psychological therapy. Acutely enhancing particular biological or psychological processes during psychological therapy may improve treatment outcomes. However, previous studies are confined to specific augmentation approaches, typically assessed within single diagnostic categories. Our objective was to assess to what degree acute augmentations of psychological therapy reduce psychiatric symptoms and estimate effect sizes of augmentation types (for example, brain stimulation or psychedelics). We searched Medline, PsycINFO and Embase for controlled studies published between database inception and 25 May 2022. We conducted a preregistered random-effects meta-analysis (PROSPERO CRD42021236403). We identified 108 studies (N = 5,889). Acute augmentation significantly reduced the severity of mental health problems (Hedges' g = -0.27, 95% CI: [-0.36, -0.18]; P < 0.0001), particularly for the transdiagnostic dimensions 'Fear' and 'Distress'. This result survived a trim-and-fill analysis to account for publication bias. Subgroup analyses revealed that pharmacological, psychological and somatic augmentations were effective, but to varying degrees. Acute augmentation approaches are a promising route to improve outcomes from psychological therapy.

Transdiagnostic internet-delivered cognitive behaviour therapy: Feasibility of a motivational interviewing resource

BACKGROUND

Despite growing evidence for the effectiveness of internet-delivered cognitive behaviour therapy (ICBT), engagement and treatment outcomes are lower for some clients. Online motivational interviewing (MI) has been investigated prior to offering ICBT to facilitate engagement and outcomes, but only appears to improve engagement.

PURPOSE

This feasibility study investigated the potential use of a brief MI resource offered during ICBT rather than before, by examining: (1) use of the resource; (2) client and treatment variables associated with use; (3) whether use of the resource was associated with improved engagement and outcomes; and (4) how those who used the resource evaluated it.

METHOD

This study used data collected from 763 clients enrolled in an ICBT course. Symptoms related to depression, anxiety and disability were assessed at pre- and post-treatment. The website tracked treatment engagement. Clients completed an MI resource evaluation measure at post-treatment.

RESULTS

Approximately 15% of clients used the resource. Clients who were older, had higher education, scored in the clinical range on depression, and scored lower on anxiety at pre-treatment were more likely to use the resource. Those who reported using the resource had higher engagement (i.e., more lessons and messages) in ICBT, but lower improvement in disability post-treatment. Positive feedback on the MI resource outweighed negative feedback, with 94 % of clients identifying a positive aspect of the resource and 66 % of clients reporting making changes in response to the resource. Overall, the MI resource appears to be used by and perceived as beneficial by a small portion of clients who complete ICBT. The study provides insight into use of the resource and directions for future research related to MI and ICBT.

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.
