Comorbidity between substance use disorders and psychiatric conditions

Abstract: Aims To review information relevant to the question of whether substance-induced mental disorders exist and their implications. Design and method This paper utilized a systematic review of manuscripts published in the English language since approximately 1970 dealing with comorbid psychiatric and substance use disorders. Findings The results of any specific study depended on the definitions of comorbidity, the methods of operationalizing diagnostic criteria, the interview and protocol invoked several additional methodological issues. The results generally support the conclusion that substance use mental disorders exist, especially regarding stimulant or cannabinoid-induced psychoses, substance-induced mood disorders, as well as substance-induced anxiety conditions. Conclusions The material reviewed indicates that induced disorders are prevalent enough to contribute significantly to rates of comorbidity between substance use disorders and psychiatric conditions, and that their recognition has important treatment implications. The current literature review underscores the heterogeneous nature of comorbidity.

Responsiveness in psychotherapy.

Abstract: Human interaction, including psychotherapy, is systematically responsive; therapists' and clients' behavior is influenced by emerging context, including perceptions of each other's characteristics and behavior. Feedback and mutual influence occur on a wide range of time scales, including treatment assignment, strategy, and tactics, -and even within the delivery of interventions. Consequently, research that assumes linear relations among psychotherapeutic variables may not be trustworthy. The concept of responsiveness helps show how client characteristics, therapist characteristics, and process components may be important in psychotherapy despite a lack of linear relations to outcomes. Research strategies that incorporate responsiveness include the use of evaluative measures, systems approaches, and qualitative and narrative approaches.

Reporting bias in medical research - a narrative review.

Abstract: Reporting bias represents a major problem in the assessment of health care interventions. Several prominent cases have been described in the literature, for example, in the reporting of trials of antidepressants, Class I anti-arrhythmic drugs, and selective COX-2 inhibitors. The aim of this narrative review is to gain an overview of reporting bias in the medical literature, focussing on publication bias and selective outcome reporting. We explore whether these types of bias have been shown in areas beyond the well-known cases noted above, in order to gain an impression of how widespread the problem is. For this purpose, we screened relevant articles on reporting bias that had previously been obtained by the German Institute for Quality and Efficiency in Health Care in the context of its health technology assessment reports and other research work, together with the reference lists of these articles. We identified reporting bias in 40 indications comprising around 50 different pharmacological, surgical (e.g. vacuum-assisted closure therapy), diagnostic (e.g. ultrasound), and preventive (e.g. cancer vaccines) interventions. Regarding pharmacological interventions, cases of reporting bias were, for example, identified in the treatment of the following conditions: depression, bipolar disorder, schizophrenia, anxiety disorder, attention-deficit hyperactivity disorder, Alzheimer's disease, pain, migraine, cardiovascular disease, gastric ulcers, irritable bowel syndrome, urinary incontinence, atopic dermatitis, diabetes mellitus type 2, hypercholesterolaemia, thyroid disorders, menopausal symptoms, various types of cancer (e.g. ovarian cancer and melanoma), various types of infections (e.g. HIV, influenza and Hepatitis B), and acute trauma. Many cases involved the withholding of study data by manufacturers and regulatory agencies or the active attempt by manufacturers to suppress publication. The ascertained effects of reporting bias included the overestimation of efficacy and the underestimation of safety risks of interventions. In conclusion, reporting bias is a widespread phenomenon in the medical literature. Mandatory prospective registration of trials and public access to study data via results databases need to be introduced on a worldwide scale. This will allow for an independent review of research data, help fulfil ethical obligations towards patients, and ensure a basis for fully-informed decision making in the health care system.

Cognitive and behavioral treatments for anxiety disorders: A review of meta-analytic findings

Abstract: Behavioral and cognitive psychotherapies are the most widely studied psychological interventions for anxiety disorders. In the present article, the results of ten years of meta-analytic studies on psychotherapies for the various anxiety disorders are reviewed and the relative effectiveness of cognitive and behavioral therapeutic methods is examined. Meta-analytic results support the effectiveness of combined cognitive and behavioral approaches for anxiety disorders. Pure behavioral therapies also are effective and appear to work as well as combined treatment for some disorders. Due to the small number of outcome studies involving pure cognitive treatments, reliable conclusions about the effectiveness of this approach cannot be offered. Additional theoretical and practical considerations are discussed.

Stigma in response to mental disorders: a comparison of Australia and Japan

Abstract: There are few national or cross-cultural studies of the stigma associated with mental disorders. Australia and Japan have different systems of psychiatric health care, and distinct differences in cultural values, but enjoy similar standards of living. This study seeks to compare the nature and extent of stigma among the public in the two countries. A household survey of the public was conducted in each country using similar methodologies. The Australian study comprised a national survey of 3998 adults aged over 18 years. The Japanese survey involved 2000 adults aged 20 to 69 from 25 regional sites distributed across the country. Interviewees reported their personal attitudes (personal stigma, social distance) and perceptions of the attitudes of others (perceived stigma, perceived discrimination) in the community with respect to four case vignettes. These vignettes described a person with: depression; depression with suicidal ideation; early schizophrenia; and chronic schizophrenia. Personal stigma and social distance were typically greater among the Japanese than the Australian public whereas the reverse was true with respect to the perception of the attitudes and discriminatory behaviour of others. In both countries, personal stigma was significantly greater than perceived stigma. The public in both countries showed evidence of greater social distance, greater personal stigma and greater perceived stigma for schizophrenia (particularly in its chronic form) than for depression. There was little evidence of a difference in stigma for depression with and without suicide for either country. However, social distance was greater for chronic compared to early schizophrenia for the Australian public. Stigmatising attitudes were common in both countries, but negative attitudes were greater among the Japanese than the Australian public. The results suggest that there is a need to implement national public awareness interventions tailored to the needs of each country. The current results provide a baseline for future tracking of national stigma levels in each country.
