Identifying depression and anxiety disorders in people presenting for substance use treatment

Objective: To identify the type and proportion of depressive and related mental health disorders in a group of individuals seeking outpatient treatment at an alcohol and other drug (AOD) service.
Design, setting and participants: A cross-sectional study using diagnostic interviews with 95 participants (56 men, 39 women) seeking treatment from an AOD service.
Main outcome measures: Mental health and substance disorders were measured using the Composite International Diagnostic Interview, Posttraumatic Stress Disorder Checklist, Beck Depression Inventory, and State–Trait Anxiety Inventory (Trait Version).
Results: This was a complex group with addiction, mental health and physical health conditions; 76% had a depressive disorder and 71% had an anxiety disorder. Most were diagnosed with at least two mental health disorders and 25% were diagnosed with four or more different disorders. Alcohol and cannabis use were the most commonly diagnosed AOD disorders. Further, those diagnosed with a drug use disorder reported significantly higher levels of depression compared with those with an alcohol-only disorder. Finally, 60% of the sample reported chronic health conditions, with over one third taking medication for a physical condition on a regular basis.
Conclusions: Primary care providers such as general practitioners are likely to be increasingly called on to assess, treat and/or coordinate care of patients with AOD disorders. We show that this group will likely present to their GP with more than one MJA 2011; 195: S60–S63 mental health disorder in addition to acute and chronic physical health conditions.

An empirical analysis of the effects of the exchange rate on Canadian tourism

The effects of depreciation of the Canadian dollar on the Canadian tourist industry are estimated, and it is shown that the exchange rate had a modest impact in attracting U. S. visitors to Canada. However, the favorable exchange rate effects seem to be offset by other factors.

Anxiety online - a virtual clinic : preliminary outcomes following completion of five fully automated treatment programs for anxiety disorders and symptoms

Background : The development of e-mental health interventions to treat or prevent mental illness and to enhance wellbeing has risen rapidly over the past decade. This development assists the public in sidestepping some of the obstacles that are often encountered when trying to access traditional face-to-face mental health care services. Objective : The objective of our study was to investigate the posttreatment effectiveness of five fully automated self-help cognitive behavior e-therapy programs for generalized anxiety disorder (GAD), panic disorder with or without agoraphobia (PD/A), obsessive–compulsive disorder (OCD), posttraumatic stress disorder (PTSD), and social anxiety disorder (SAD) offered to the international public via Anxiety Online, an open-access full-service virtual psychology clinic for anxiety disorders. Methods : We used a naturalistic participant choice, quasi-experimental design to evaluate each of the five Anxiety Online fully automated self-help e-therapy programs. Participants were required to have at least subclinical levels of one of the anxiety disorders to be offered the associated disorder-specific fully automated self-help e-therapy program. These programs are offered free of charge via Anxiety Online. Results : A total of 225 people self-selected one of the five e-therapy programs (GAD, n = 88; SAD, n = 50; PD/A, n = 40; PTSD, n = 30; OCD, n = 17) and completed their 12-week posttreatment assessment. Significant improvements were found on 21/25 measures across the five fully automated self-help programs. At postassessment we observed significant reductions on all five anxiety disorder clinical disorder severity ratings (Cohen d range 0.72–1.22), increased confidence in managing one’s own mental health care (Cohen d range 0.70–1.17), and decreases in the total number of clinical diagnoses (except for the PD/A program, where a positive trend was found) (Cohen d range 0.45–1.08). In addition, we found significant improvements in quality of life for the GAD, OCD, PTSD, and SAD e-therapy programs (Cohen d range 0.11–0.96) and significant reductions relating to general psychological distress levels for the GAD, PD/A, and PTSD e-therapy programs (Cohen d range 0.23–1.16). Overall, treatment satisfaction was good across all five e-therapy programs, and posttreatment assessment completers reported using their e-therapy program an average of 395.60 (SD 272.2) minutes over the 12-week treatment period. Conclusions : Overall, all five fully automated self-help e-therapy programs appear to be delivering promising high-quality outcomes; however, the results require replication.

Post-traumatic stress disorder and quality of life in sexually abused Australian children

The study used publicly available data on post-traumatic stress disorder in a sample of the Australian population with a history of sexual abuse to demonstrate how this evidence can inform economic analyses. The 2007 Australian Mental Health Survey revealed that 8.3% of 993 adolescents experienced childhood sexual abuse, of which 40.2% were diagnosed with post-traumatic stress disorder. Post-traumatic stress disorder diagnosis corresponded to a significant loss of quality of life. Survival analysis was used to estimate the lifetime persistence of post-traumatic stress disorder symptoms. The average time between post-traumatic stress disorder onset and remission was 11.4 years. Results suggest that successful treatment of post-traumatic stress disorder will save 2.05 quality adjusted life years per child or adolescent with post-traumatic stress disorder.

Nutritional psychiatry research: an emerging discipline and its intersection with global urbanization, environmental challenges and the evolutionary mismatch

In 21st-century public health, rapid urbanization and mental health disorders are a growing global concern. The relationship between diet, brain function and the risk of mental disorders has been the subject of intense research in recent years. In this review, we examine some of the potential socioeconomic and environmental challenges detracting from the traditional dietary patterns that might otherwise support positive mental health. In the context of urban expansion, climate change, cultural and technological changes and the global industrialization and ultraprocessing of food, findings related to nutrition and mental health are connected to some of the most pressing issues of our time. The research is also of relevance to matters of biophysiological anthropology. We explore some aspects of a potential evolutionary mismatch between our ancestral past (Paleolithic, Neolithic) and the contemporary nutritional environment. Changes related to dietary acid load, advanced glycation end products and microbiota (via dietary choices and cooking practices) may be of relevance to depression, anxiety and other mental disorders. In particular, the results of emerging studies demonstrate the importance of prenatal and early childhood dietary practices within the developmental origins of health and disease concept. There is still much work to be done before these population studies and their mirrored advances in bench research can provide translation to clinical medicine and public health policy. However, the clear message is that in the midst of a looming global epidemic, we ignore nutrition at our peril.

Selecting outcomes for intimate partner violence intervention trials: overview and recommendations

 Intimate partner violence (IPV) is endemic in societies around the world and detrimental to women's wellbeing. Abused women are frequent users of health services. Despite the recent World Health Organization guidelines on IPV and sexual violence, we need more evidence on effective responses to women in health care settings. Developing robust evidence with potential to inform policy and clinical practice requires greater clarity and consistency across studies in the selection and use of outcomes to evaluate interventions. Drawing on systematic reviews and individual trials aimed at reducing abuse and improving women's health, we discuss critical issues in respect of outcomes. We discuss primary, secondary, intermediate and proxy outcomes and measures used to evaluate interventions for women who experience IPV. We offer recommendations about which outcomes to assess and approaches to doing so within the context of trials in health care settings. © 2014 Elsevier Ltd. All rights reserved.

Association between attributions of responsibility for motor vehicle crashes, depressive symptoms, and return to work.

Perceptions surrounding the underlying causes of accidents and injuries may be a key mechanism influencing postaccident health and functional outcomes among people injured in road crashes. In particular, attributions of responsibility may influence rates of postcrash depressive symptomatology and return-to-work.

Different clinical courses of children exposed to a single incident of psychological trauma: a 30-month prospective follow-up study

We investigated the distinct longitudinal trajectories of posttraumatic stress symptoms in a sample of 167 children, who witnessed death of two mothers of their schoolmates.

Experience and expression of anger among Australian prisoners and the relationship between anger and reintegration variables

We examined the experience and expression of anger among a group of Australian prisoners prior to and following prison release, as well as the relationship between anger and several reintegration variables. Participants were 79 adult prisoners (54 male, 25 female) who completed the State-Trait Anger Expression Inventory (STAXI-2) 1 month prior to release and again at 1 to 4 weeks and 3 to 4 months post-release. A postrelease questionnaire was also administered at the two postrelease points focusing on the quality of life conditions experienced following release. Mean state and trait anger scores were significantly higher at pre-release than post-release. As well, higher levels of anger expression and anger control were reported at pre-release compared with post-release. Higher age was related to lower state anger at post-release, whereas several variables were related to trait anger at post-release. Theoretical implications for reintegration theory are discussed, together with practical applications.

Selective serotonin reuptake inhibitors in mixed anxiety-depression.

The overlap between the depressive and anxiety disorders is extremely common. The introduction of the selective serotonin reuptake inhibitors (SSRIs) has, more than any other development, bridged the gap in terms of efficacy in both sets of disorders. A substantial body of data exists suggesting that the available SSRIs have substantial efficacy in anxiety symptoms co-occurring with depression. The clear utility of the SSRIs in disorders classified apart from depression is also established. Whilst panic disorder is the best studied, evidence on the efficacy of the SSRIs in disorders that previously did not attract much pharmacotherapeutic interest, such as social anxiety disorder and post-traumatic stress disorder is accumulating.

Effects of persisting emotional impact from child abuse and norepinephrine transporter genetic variation on antidepressant efficacy in major depression: a pilot study

OBJECTIVE: Previous studies suggest child abuse and serotonergic polymorphism influence depression susceptibility and antidepressant efficacy. Polymorphisms of the norepinephrine transporter (NET) may also be involved. Research in the area is possibly clouded by under reporting of abuse in researcher trials. METHODS: Adults (n=51) with major depressive disorder has 8 weeks treatment with escitalopram or venlafaxine. Abuse history was obtained, the ongoing emotional impact of which was measured with the 15-item impact of event scale (IES-15). The 17-item Hamilton Depression Rating Scale (HDRS) was applied serially. Two NET polymorphisms (rs2242446 and rs5569) were assayed, blinded to HDRS ratings and abuse history. RESULTS: No subjects reporting abuse with high impact in adulthood (IES-15 ≥26, n=12) remitted; whereas 77% reporting low impact (IES-15 <26; n=26) remitted (p<0.001). Subjects reporting high impact abuse (n=12) had a 50-fold (95% confidence interval=4.85-514.6) greater odds of carrying rs2242446-TT genotype, but the small sample size leaves this finding vulnerable to type I error. CONCLUSIONS: The level of persisting impact of child abuse appears relevant to antidepressant efficacy, with susceptibility to such possibly being influence by NET rs2242446 polymorphism. Larger studies may be merited to expand on this pilot level finding given potential for biomarker utility.

Symptoms of PTSD associated with painful and nonpainful vicarious reactivity following amputation

Although the experience of vicarious sensations when observing another in pain have been described postamputation, the underlying mechanisms are unknown. We investigated whether vicarious sensations are related to posttraumatic stress disorder (PTSD) symptoms and chronic pain. In Study 1, 236 amputees completed questionnaires about phantom limb phenomena and vicarious sensations to both innocuous and painful sensory experiences of others. There was a 10.2% incidence of vicarious sensations, which was significantly more prevalent in amputees reporting PTSD-like experiences, particularly increased arousal and reexperiencing the event that led to amputation (φ = .16). In Study 2, 63 amputees completed the Empathy for Pain Scale and PTSD Checklist-Civilian Version. Cluster analyses revealed 3 groups: 1 group did not experience vicarious pain or PTSD symptoms, and 2 groups were vicarious pain responders, but only 1 had increased PTSD symptoms. Only the latter group showed increased chronic pain severity compared with the nonresponder group (p = .025) with a moderate effect size (r = .35). The findings from both studies implicated an overlap, but also divergence, between PTSD symptoms and vicarious pain reactivity postamputation. Maladaptive mechanisms implicated in severe chronic pain and physical reactivity posttrauma may increase the incidence of vicarious reactivity to the pain of others.

Effects of the SEC's XBRL mandate on financial reporting comparability

© 2015 Elsevier Inc. In 2009, the US Securities and Exchange Commission (SEC) made it mandatory for firms to file interactive data using XBRL along with their 10-K and 10-Q reports on EDGAR. There was an initial three-year phase-in period, with the first (last) phase covering the largest (smallest) firms in the US capital markets. We examine the implications of the SEC's XBRL mandate for financial statement comparability. Our results indicate that financial statement comparability declined in the initial years after the mandate. We also find that firms that use more company-specific extension taxonomies (companies are allowed to use their own taxonomies when the standard taxonomy provided by the Financial Accounting Standards Board (FASB) is inadequate) have lower financial statement comparability in the post-mandate years. Finally, we document that the level of discretion involved in measuring particular financial statement line items is related to the post-mandate change in comparability - we find that selling, general and administrative expense (SG&A) comparability declined after the mandate, while depreciation comparability did not change.
