Prevalence and clinical characteristics of remission during treatment in generalized anxiety

Psychological interventions for generalized anxiety disorder: Effects and predictors in a naturalistic outpatient setting

OBJECTIVE

Numerous randomized controlled trials (RCTs) demonstrate the efficacy of cognitive behavioral therapy (CBT), metacognitive therapy (MCT), and methods to reduce intolerance of uncertainty (IU-CBT) in the treatment of generalized anxiety disorder (GAD). However, few studies have investigated these treatments under conditions of routine clinical care. The main objective of this study was to investigate the effectiveness of psychotherapy for GAD in an outpatient setting and to identify factors influencing treatment outcome.

METHODS

Fifty-nine GAD patients received naturalistic CBT (including MCT and IU-CBT) in an outpatient clinic and postgraduate training center for psychotherapy. Patients completed self-report questionnaires at the beginning and end of therapy regarding the main outcome worry as well as metacognitions, intolerance of uncertainty, depression, and general psychopathology.

RESULTS

Worry, negative metacognitions, intolerance of uncertainty, depression, and general psychopathology decreased significantly (p's < .001) with large effect sizes for all symptoms (d = 0.83-1.49). A reliable change in the main outcome worry was observed in 80% of patients, and recovery occurred in 23%. Higher worry scores at posttreatment were predicted by higher pretreatment scores, female sex, and less change in negative metacognitive beliefs during treatment.

CONCLUSIONS

Naturalistic CBT for GAD appears to be effective in routine clinical care for worry as well as depressive symptoms, with particular benefits associated with altering negative metacognitions. However, a recovery rate of only 23% is lower than the rates reported in RCTs. Treatment needs to be improved, especially for patients with more severe GAD and for women.

Utilisation and predictors of use of exposure therapy in the treatment of anxiety, OCD and PTSD in an Australian sample: a preliminary investigation

BACKGROUND

Cognitive-behavior therapy (CBT) is known to be an effective treatment for the anxiety and related disorders, with exposure therapy being a key component of this treatment package. However, research on the use of exposure therapy in clinical practice has presented mixed results, potentially due to differences in samples and training programs across countries. The present study aimed to extend upon existing research by examining the use and predictors of use of exposure therapy in a sample of psychologists working in clinical practice in Australia who treat clients with an anxiety disorder, obsessive compulsive disorder (OCD) or post-traumatic stress disorder (PTSD).

METHODS

One hundred registered psychologists (M_age = 40.60; SD = 10.78; range 23 to 71 years; 84% female) participated in an online study investigating their clinical practices.

RESULTS

Results suggested that while the general use of exposure therapy is high, the use of disorder specific techniques was considerably lower, particularly for anxiety disorders and PTSD but not OCD. Psychology registration status and level of training were positively associated with use of exposure therapy as was the experience in treating anxiety disorders.

CONCLUSIONS

These findings suggest that further or ongoing professional training may be required to optimize the use of disorder specific techniques.

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.

Achieving complete mental health despite a history of generalized anxiety disorders: Findings from a large, nationally representative Canadian survey

Ideally, the clinical goal for individuals with a history of anxiety disorder is not only to remit from the disorder, but also to reach optimal well-being. This broader concept of recovery aligns with Keyes' concept of complete mental health (CMH), including presence of happiness or life satisfaction, and social and psychological well-being, and absence of any past year mental illness including anxiety disorders, depressive disorders, substance dependence and suicidal ideation. This study's aim was to identify factors associated with CMH in a population-based sample of Canadians with a previous diagnosis of Generalized Anxiety Disorder (GAD) (n = =2128), of whom 40% are currently in CMH. Data were from the 2012 Canadian Community Health Survey-Mental Health (response rate=68.9%). The World Health Organization version of the Composite International Diagnostic Interview (WHOCIDI) scales were used to define lifetime and past-year GAD. Factors associated with complete mental health include female gender, older age, being married, reporting good to excellent physical health, being free of chronic insomnia, being able to manage household activities without difficulties, using religion or spirituality to cope, having a confidant, and never having had a major depressive disorder nor substance dependence. Results of this study suggest many with a history of anxiety disorders can achieve CMH and point to factors that appear to facilitate this process.

Generalized anxiety disorder: psychopharmacotherapy update on a common and commonly overlooked condition

OBJECTIVE

This article provides a brief review of the practical implications of the current diagnostic conceptualisation of generalised anxiety disorder (GAD) and an update on its pharmacotherapy.

CONCLUSIONS

The diagnostic criteria for GAD need to be refined, to better reflect its clinical features and to make GAD more clinically useful. Various pharmacological agents are effective for GAD and to some extent, allow a tailored treatment approach. In addition to effectiveness, the choice of medication is influenced by the speed of therapeutic action, tolerability and habit-forming properties.
