The Use of Evidence-Based Assessment for Anxiety Disorders in an Australian Sample

Anxiety disorders are common and cause considerable functional impairment. Fortunately, evidence-based treatments are available, however, treatment effectiveness is often reliant on the provision of an accurate diagnosis. Accurate diagnosis requires a multi-method evidence-based assessment (EBA). Assessment techniques available to clinicians include a clinical interview, semi-structured diagnostic interview, self-report/clinician-administered rating scales and direct observation. Research demonstrates that only a small number of therapists utilize EBA, and to date this has not been investigated in an Australian sample. One hundred and two registered Australian psychologists (M_age = 40.98; SD = 12.67; 83.6% female) participated in an online study investigating assessment practices. Participants were asked to indicate EBA frequency of use and the obstacles they face to using EBA. The majority of participants (69% working with adult patients and 51% working with pediatric patients) reported partial use of EBA. Few psychologists (21% working with adult patients and 11% working with child patients) indicated complete use of EBA. Thirty-six percent of participants indicated negative beliefs about the usefulness or helpfulness of EBA. Multiple obstacles to the use of EBA were reported including concerns with the time required to complete assessment (27%), and a lack of access to assessment tools (10%). Implications for training and clinical practice are discussed.     

A meta-analysis of relapse rates in cognitive-behavioral therapy for anxiety disorders

Cognitive-behavioral therapy (CBT) is a first-line treatment for anxiety and related disorders, with large pre- to post-treatment effect sizes. Rates of relapse, or the likelihood that a state of remission will be maintained once treatment is withdrawn, have been relatively neglected in CBT outcome studies. The present meta-analysis aimed to determine the overall rate of relapse in CBT for anxiety and related disorders. A secondary aim was to assess whether demographic, clinical, and methodological factors were associated with rates of relapse in CBT. Articles were identified from prior CBT meta-analyses and review papers and from literature searches using the PsycINFO and Medline electronic databases, with 17 full-length articles retained for meta-analysis (total N = 337 patients). Results showed an overall relapse rate of 14 %, which did not significantly differ between diagnoses. The way in which relapse was defined was significantly associated with relapse rates; when relapse was defined as meeting diagnostic criteria, estimates were lower than when alternative definitions were used. The findings indicate that relapse following symptom remission occurs in a minority of patients, suggesting that future treatment development and refinement efforts should focus on improving relapse prevention skills and interventions to minimize risk of relapse.     

Within and between associations of nonverbal synchrony in relation to Grawe's general mechanisms of change

The examination of nonverbal synchrony has become a promising line of psychotherapy research. Although several studies have found between-dyad associations between nonverbal synchrony and multidimensional outcomes, the findings remain heterogeneous, and within-dyad effects remain to be investigated. The present study examines within and between effects of nonverbal synchrony on mastery, resource activation, problem actuation, and motivational clarification (Grawe's general mechanisms of change). Four-hundred and twenty-three videotaped sessions of 175 patients were analysed using motion energy analysis (MEA), providing values to quantify nonverbal synchrony in the patient–therapist dyad. Grawe's general mechanisms of change in psychotherapy were rated using the Inventory of Therapeutic Interventions and Skills (ITIS). On average, patient–therapist nonverbal synchrony was greater than chance. Hierarchical linear modelling revealed that nonverbal synchrony was significantly associated with higher mastery and less resource activation on the within-dyad level. Nonverbal synchrony was not associated with problem actuation or motivational clarification, and in general, no associations were found on the between-dyad level. The results demonstrate the importance of disentangling within and between effects of nonverbal synchrony and provide initial evidence that nonverbal synchrony is tied to the specific therapeutic strategies observed in psychotherapy sessions.     

Measuring therapeutic alliance in children with autism during cognitive behavior therapy

Therapeutic alliance (TA), or the collaborative relationship between a therapist and client, has been shown to be an important component of intervention success. The objective of this study was to examine the psychometric properties of the Therapy Process Observational Coding System–Alliance Scale (TPOCS‐A). The sample consisted of 20 children (19 males) ages 8 to 12 years with autism and their parents (15 mothers, 5 fathers), who completed a cognitive–behavioural intervention designed to improve children's emotion regulation skills. Two trained coders rated early, middle, and late parent and child alliance using the TPOCS‐A after watching video recorded therapy sessions. Therapist‐reported child involvement, alliance, and adherence were also assessed. Psychometric findings revealed that the TPOCS‐A is a reliable and valid measure of therapeutic alliance for children with autism. The implications of examining TA in empirically supported treatments for this population are discussed.     

Latent class growth analyses reveal overrepresentation of dysfunctional fear conditioning trajectories in patients with anxiety-related disorders compared to controls

Recent meta-analyses indicated differences in fear acquisition and extinction between patients with anxiety-related disorders and comparison subjects. However, these effects are small and may hold for only a subsample of patients. To investigate individual trajectories in fear acquisition and extinction across patients with anxiety-related disorders (N = 104; before treatment) and comparison subjects (N = 93), data from a previous study (Duits et al., 2017) were re-analyzed using data-driven latent class growth analyses. In this explorative study, subjective fear ratings, shock expectancy ratings and startle responses were used as outcome measures. Fear and expectancy ratings, but not startle data, yielded distinct fear conditioning trajectories across participants. Patients were, compared to controls, overrepresented in two distinct dysfunctional fear conditioning trajectories: impaired safety learning and poor fear extinction to danger cues. The profiling of individual patterns allowed to determine that whereas a subset of patients showed trajectories of dysfunctional fear conditioning, a significant proportion of patients (≥50 %) did not. The strength of trajectory analyses as opposed to group analyses is that it allows the identification of individuals with dysfunctional fear conditioning. Results suggested that dysfunctional fear learning may also be associated with poor treatment outcome, but further research in larger samples is needed to address this question.

Depression Treatment Options for Individuals With Developmental Disabilities

This research project was conducted in a group home in Illinois. It used a quasiexperimental design to implement a cognitive behavior therapy (CBT) protocol for treating minimal/mild depression in individuals with mild/moderate intellectual disabilities. This was done through a 2-fold approach that involved providing an educational module to the group home’s clinical staff on depression recognition and treatment and providing the patients with minimal/mild depression with weekly CBT for 10 weeks. The results showed statistically significant increases in staff’s confidence and knowledge after attending training. Similarly, patients who underwent CBT showed a statistically significant decrease in depressive symptoms.     

Group cognitive behavioural therapy for psychosis in the Asian context: a review of the recent studies

Abstract

The cardinal symptoms of psychosis include hallucination and delusion, which can be both distressing and disabling. International guidelines recommend cognitive behavioural therapy for psychosis (CBTp) as an adjunctive intervention to medication management. Considering the difficulty in the widespread dissemination of the individual CBTp, group CBTp is an alternative in improving patients’ access to psychological intervention. Although it has been found feasible and effective in various studies, systematic review on group CBTp, particularly in Asia, was not identified. Hence, this systematic review tried to examine the recent evidence of group CBTp in Asia in order to shed light on its implementation in routine psychiatric care. A relevant literature search was conducted in three databases (Pubmed, Web of Knowledge, and PsycINFO) during the period from January 2000 to December 2018. A total of 114 journal articles were identified. After a full-text review, four studies met our inclusion and exclusion criteria. Despite methodological shortcomings, positive results were found in terms of improvements on psychotic symptoms, functioning, and quality-of-life. These encouraging results indicate the need for future research studies with more rigorous methodology, leading to a better understanding on the applicability and effectiveness of group CBTp in the Asian context.     

Combining CBT and Behavior-Analytic Approaches to Target Severe Emotion Dysregulation in Verbal Youth With ASD and ID

ABSTRACT

This article presents an individual intervention combining cognitive-behavioral and behavior-analytic approaches to target severe emotion dysregulation in verbal youth with autism spectrum disorder (ASD) concurrent with intellectual disability (ID). The article focuses on two specific individuals who received the treatment within a therapeutic school setting. Single-subject methodology utilizing a nonconcurrent multiple-baseline design across behaviors and participants was used to evaluate the intervention. The two participants presented with severe behavioral challenges, including physical aggression and verbal threats to harm others. Results suggest positive outcomes, including a reduction in the frequency and intensity of severe aggressive behavior and an increase in the use of coping skills, self-advocacy, and social participation. The planning and implementation of specific skills-generalization strategies was one innovative element of the intervention that proved to be pivotal to its successful application. Assessment and treatment techniques for different intervention phases are detailed along with two case examples. Intervention challenges, treatment outcomes, and future directions for clinical research are discussed.
