Objective: To provide practical clinical guidance for the treatment of adults with panic disorder, social anxiety disorder and generalised anxiety disorder in Australia and New Zealand.
Method:Relevant systematic reviews and meta-analyses of clinical trials were identified by searching PsycINFO, Medline, Embase and Cochrane databases. Additional relevant studies were identified from reference lists of identified articles, grey literature and literature known to the working group. Evidence-based and consensus-based recommendations were formulated by synthesising the evidence from efficacy studies, considering effectiveness in routine practice, accessibility and availability of treatment options in Australia and New Zealand, fidelity, acceptability to patients, safety and costs. The draft guidelines were reviewed by expert and clinical advisors, key stakeholders, professional bodies, and specialist groups with interest and expertise in anxiety disorders.
Results:The guidelines recommend a pragmatic approach beginning with psychoeducation and advice on lifestyle factors, followed by initial treatment selected in collaboration with the patient from evidence-based options, taking into account symptom severity, patient preference, accessibility and cost. Recommended initial treatment options for all three anxiety disorders are cognitive-behavioural therapy (face-to-face or delivered by computer, tablet or smartphone application), pharmacotherapy (a selective serotonin reuptake inhibitor or serotonin and noradrenaline reuptake inhibitor together with advice about graded exposure to anxiety triggers), or the combination of cognitive-behavioural therapy and pharmacotherapy.
The second-order factor structure of the Devereux Adolescent Behavior Rating Scale was examined in (a) a sample of 254 adolescents who were receiving residential treatment for severe emotionaVbehavior disorders and (b) an independent sample of 404 adolescents hospitalized for substance abuse. A plausible range of factors was estimated for each group through parallel and average partial analyses and suggested either a two-or threefactor solution. Subsequent congruence analyses provided tentative support for a three-factor model: (a) undercontrolled/disruptive behaviors; (b) withdrawn/psychotic behaviors; and (c) needs approvaVdependent behaviors. The third factor was poorly defined in the residential treatment sample, but extraction of the third factor increased the across-group replicability of the first two factors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
