Quality of Internet information referring to mental health and mental disorders in Japan

Although the Internet has been widely used in Japan, the quality of information on mental health-related issues has not been evaluated so far. The purpose of the present study was to investigate the current status of Japanese websites that deal with mental health, mental disorders, and their associated matters. Using a search engine, Google, 37 websites were identified that exclusively contain information on mental health or mental disorders. The characteristics of the sites were then examined, along with variety of mental disorders mentioned, and quality of contents for each of the 37 websites. More than half of the websites were set up, at least in part, for commercial purposes and only 27% of sites were owned by professionals. Mood disorder, panic disorder, and schizophrenia were the three most commonly referred disorders on websites. Aside from some exceptions, the quality of information was inadequate, especially that regarding treatment. Most of the websites on mental health and mental disorders examined in the present study have scope for improvement. The challenge is to establish a system to evaluate the sites and to motivate each webmaster to improve the sites.     

Treatments for Neurodevelopmental Disorders: Evidence, Advocacy, and the Internet

The Internet is a major source of health-related information for parents of sick children despite concerns surrounding quality. For neurodevelopmental disorders, the websites of advocacy groups are a largely unexamined source of information. We evaluated treatment information posted on nine highly-trafficked advocacy websites for autism, cerebral palsy, and fetal alcohol spectrum disorder. We found that the majority of claims about treatment safety and efficacy were unsubstantiated. Instead, a range of rhetorical strategies were used to imply scientific support. When peer-reviewed publications were cited, 20 % were incorrect or irrelevant. We call for new partnerships between advocacy and experts in developmental disorders to ensure better accuracy and higher transparency about how treatment information is selected and evidenced on advocacy websites.     

Attention-deficit hyperactivity disorder, drug companies and the internet

This study investigated the influence of drug-company funding on websites about attention-deficit hyperactivity disorder (ADHD). Websites in the top 60 for either Google or Yahoo!Xtra with information about causation and treatment were analysed. Likert scales, based on those used in previous similar studies, were developed to rate aetiological explanations and recommended treatment approaches, on a dimension from psycho-social to biological. Overall, the quality of information on websites was poor with a strong bias towards bio-genetic aetiological explanations of ADHD. Twenty-one of the 57 websites (37%) were funded by drug companies. The drug-company funded (DCF) websites were significantly more likely than non-DCF websites to recommend medication rather than psycho-social treatments. The selective lack of consideration of psycho-social treatments by DCF websites is discussed in relation to the relevant research literature, including the evidence in favour of a multimodal approach. The findings, which are consistent with previous similar studies in relation to websites about adult mental health problems, confirm that the pharmaceutical industry is seeking to influence public opinion via the internet.     

Online mental health resources for teenagers: an evaluation of two websites developed for adolescents

Young people are less likely to seek help for mental health difficulties. Good quality mental health information from reliable sources may help overcome barriers to help seeking in young people and improve awareness of the common symptoms related to mental health problems. With an adolescent population in mind, websites for depression and for stress and anxiety were developed for young people and those caring for them by one of the authors. The current evaluation sought to assess the use of, and perceived satisfaction with, each of these mental health websites. Data from the website domains were considered in relation to unique visits, country of origin and source of referral. Qualitative website user feedback was gained from evaluation questionnaires. Findings showed that website visits for both resources have increased year-on-year and feedback from the evaluation revealed that the resource information was perceived to be trustworthy, reliable and informative. The feedback indicated that the resource was perceived to be accessible and informative for adolescents. Future developments to reduce the barriers for accessing mental health are discussed.     

A review and meta-analysis of the genetic epidemiology of anxiety disorders

OBJECTIVE: The authors conducted meta-analyses of data from family and twin studies of panic disorder, generalized anxiety disorder, phobias, and obsessive-compulsive disorder (OCD) to explore the roles of genetic and environmental factors in their etiology. METHOD: MEDLINE searches were performed to identify potential primary studies of these disorders. Data from studies that met inclusion criteria were incorporated into meta-analyses that estimated summary statistics of aggregate familial risk and heritability for each disorder. RESULTS: For family studies, odds ratios predicting association of illness in first-degree relatives with affection status of the proband (disorder present or absent) were homogeneous across studies for all disorders. The calculated summary odds ratios ranged from 4 to 6, depending on the disorder. Only for panic disorder and generalized anxiety disorder could the authors identify more than one large-scale twin study for meta-analysis. These yielded heritabilities of 0.43 for panic disorder and 0.32 for generalized anxiety disorder. For panic disorder, the remaining variance in liability could be attributed primarily to nonshared environment. For generalized anxiety disorder, this was true for men, but for women, a potentially significant role for common familial environment was also seen. CONCLUSIONS: Panic disorder, generalized anxiety disorder, phobias, and OCD all have significant familial aggregation. For panic disorder, generalized anxiety disorder, and probably phobias, genes largely explain this familial aggregation; the role of family environment in generalized anxiety disorder is uncertain. The role of nonshared environmental experience is significant, underscoring the importance of identifying putative environmental risk factors that predispose individuals to anxiety.     

Childhood brain tumour information on the Internet in the Chinese language

Background Internet information, now available in many different languages, can become a major source of information for patients and families in their own mother tongue. Chinese represent one of most frequently spoken language in the world. The aims of this study were to critically appraise the quantity and quality of Internet health information in childhood brain tumour in the Chinese language and to identify sufficient quality websites that can potentially be recommended to Chinese-speaking parents.Methods Internet information on six common paediatric brain tumours was searched using six commonly used Chinese search engines. Websites were assessed systematically using two rating tools: DISCERN instrument and Checklist Rating System Instrument.Results Out of 946 sites accessed, only 13 assessable Chinese websites, displaying Traditional Chinese characters and providing information on brain tumour, were identified. Only four sites included specific discussion on brain tumours in children. Ten websites failed to provide satisfactory information on brain tumour as rated by DISCERN instrument. Overall only 41% of the 13 specific items relevant to brain tumours were mentioned (Checklist Rating System Instrument).Conclusion Only a few satisfactory websites can be recommended to Chinese-speaking families for general information on brain tumour with caution from health care providers that such information may not apply to the childs individual condition.     

Anxiety disorder comorbidity in bipolar disorder patients: data from the first 500 participants in the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD)

OBJECTIVE: The authors provide a detailed perspective on the correlates of comorbid anxiety in a large, well-characterized sample of bipolar disorder patients. METHOD: Anxiety and its correlates were examined in a cross-sectional sample from the first 500 patients with bipolar I or bipolar II disorder enrolled in the Systematic Treatment Enhancement Program for Bipolar Disorder, a multicenter project funded by the National Institute of Mental Health designed to evaluate the longitudinal outcome of patients with bipolar disorder. RESULTS: Lifetime comorbid anxiety disorders were common, occurring in over one-half of the sample, and were associated with younger age at onset, decreased likelihood of recovery, poorer role functioning and quality of life, less time euthymic, and greater likelihood of suicide attempts. Although substance abuse disorders were particularly prevalent among patients with anxiety disorders, comorbid anxiety appeared to exert an independent, deleterious effect on functioning, including history of suicide attempts (odds ratio=2.45, 95% CI=1.4-4.2). CONCLUSIONS: An independent association of comorbid anxiety with greater severity and impairment in bipolar disorder patients was demonstrated, highlighting the need for greater clinical attention to anxiety in this population, particularly for enhanced clinical monitoring of suicidality. In addition, it is important to determine whether effective treatment of anxiety symptoms can lessen bipolar disorder severity, improve response to treatment of manic or depressive symptoms, or reduce suicidality.     

Treatments and Services for Neurodevelopmental Disorders on Advocacy Websites: Information or Evaluation?

The Internet has quickly gained popularity as a major source of health-related information, but its impact is unclear. Here, we investigate the extent to which advocacy websites for three neurodevelopmental disorders??cerebral palsy (CP), autism spectrum disorder (ASD) and fetal alcohol spectrum disorder (FASD)??inform stakeholders about treatment options, and discuss the ethical challenges inherent in providing such information online. We identified major advocacy websites for each disorder and assessed website accountability, the number, attributes, and accessibility of treatments described, and the valence of treatment information. With the exception of FASD websites, we found that advocacy websites provide a plethora of information about a wide variety of readily available products and services. Treatment information is primarily targeted at families and is overwhelmingly encouraging, regardless of the type or conventionality of treatments. Many websites acknowledge corporate sponsors. While the majority do not overtly advertise or endorse specific brands, they also do not prominently display disclaimers about the nature and intent of treatment information. Thus, while advocacy websites are organized to serve as information clearinghouses, they implicitly appear to provide endorsement of selected treatments and services. We conclude with recommendations for new partnerships between government-funded health organizations, advocacy and investigators to make more transparent the role of online information in informing treatment options and improving the evaluation of information.     

Psychiatric illness in the mothers of anxious children

The authors compared maternal lifetime psychiatric illness for children with separation anxiety disorder and/or overanxious disorder (N = 58) and for children who were psychiatrically disturbed but did not manifest an anxiety or affective disorder (N = 15). The vast majority (83%) of mothers of children with separation anxiety disorder and/or overanxious disorder had a lifetime history of an anxiety disorder. Moreover, over one-half (57%) of the mothers presented with an anxiety disorder at the same time at which their children were seen for similar problems. Both of these rates significantly differed from those obtained for control subjects.     

Characteristics and Quality of Autism Websites

The World Wide Web is a common method for obtaining information on autism spectrum disorders, however, there are no guidelines for finding websites with high quality. We conducted two studies examining the characteristics and/or quality of autism websites in 2009 and 2010. We found websites with a .gov top-level domain had a statistically significant association with high quality websites and websites offering a product or service and websites promoting a non-evidence-based practice had a statistically significant association with poor quality websites. Based on our work we concluded that online information should not replace the information consumers obtain from professionals. Further implications for practice, overview of study limitations and future directions are provided.     

Social anxiety in outpatients with schizophrenia: a relevant cause of disability

OBJECTIVE: Social anxiety is a frequent but often unrecognized feature in schizophrenia and is associated with a severe level of disability. To precisely define the assessment, impact, clinical correlates, and consequences of social anxiety in schizophrenia, the authors conducted a survey of schizophrenia patients and a comparison cohort of patients with social anxiety disorder. METHOD: A consecutively enrolled group of 80 outpatients with DSM-IV schizophrenia and a consecutive comparison group of 27 patients with social anxiety disorder were recruited from an institutional psychiatric practice and assessed with the Liebowitz Social Anxiety Scale, Scale for the Assessment of Negative Symptoms, Scale for the Assessment of Positive Symptoms, Social Adjustment Scale, and the Medical Outcomes Study 36-item Short-Form Health Survey. RESULTS: Social anxiety scores of schizophrenia patients with comorbid social anxiety disorder (N=29, 36.3%) did not differ from those of subjects with social anxiety disorder as their primary diagnosis. Schizophrenia patients without social anxiety disorder had significantly lower total scores on the Liebowitz Social Anxiety Scale and lower social and performance anxiety subscale scores than did the other two groups. No differences in negative and positive symptom rates were found between schizophrenia patients with and without social anxiety disorder. Schizophrenia patients with social anxiety disorder had a higher lifetime rate of suicide attempts, greater lethality of suicide attempts, more past substance/alcohol abuse disorder, lower social adjustment, and lower overall quality of life. CONCLUSIONS: Social anxiety is a highly prevalent, disabling condition in outpatients with schizophrenia that is unrelated to clinical psychotic symptoms. The Liebowitz Social Anxiety Scale appeared adequate and reliable in assessing social anxiety disorder in patients with schizophrenia. If these data are confirmed, this study will make a contribution to the search for operational guidelines and adequate next-step treatments for social anxiety disorder in schizophrenia patients.     

Impact of generalized social anxiety disorder in managed care.

OBJECTIVE: The authors determined the costs associated with generalized social anxiety disorder in a managed care setting. METHOD: A three-phase mail and telephone survey was conducted from July to October 1998 in two outpatient clinics of a large health maintenance organization (HMO). The survey assessed direct costs, indirect costs, health-related quality of life, and clinical severity associated with generalized social anxiety disorder, both alone and with comorbid psychopathology. RESULTS: The weighted prevalence rate of current generalized social anxiety disorder was 8.2%. In the past year, only 0.5% of subjects with generalized social anxiety disorder had been accurately diagnosed. Yet 44.1% had a mental health specialty visit or had been prescribed an antidepressant, and psychiatric comorbidity was found in 43.6%. Noncomorbid generalized social anxiety disorder was associated with significantly lower health-related quality of life, work productivity, and earnings and greater utilization of health services; generalized social anxiety disorder with comorbid psychopathology was even more disabling. Suicide was attempted by 21.9% of subjects with noncomorbid generalized social anxiety disorder. Persons with average-severity generalized social anxiety disorder had probabilities of graduating from college that were 10 percentage points lower, earned wages that were 10% lower, and had probabilities of holding a technical, professional, or managerial job that were 14 percentage points lower than the comparison group. CONCLUSIONS: In a community cohort of HMO members, generalized social anxiety disorder was rarely diagnosed or treated despite being highly prevalent and associated with significant direct and indirect costs, comorbid depression, and impairment.     

Quality comparison of websites related to developmental disabilities

The Internet is commonly used to seek health-related information, but little is known about the quality of websites on developmental disabilities. Therefore, we sought to evaluate the characteristics and quality of websites located by searching ten common terms related to developmental disabilities and explore relations between website characteristics and website quality in order to make recommendations on ways to ensure locating good online information. We located 208 unique websites in our November 2012 US searches of Google and Bing. Two independent coders evaluated 10 characteristics of the websites and two different coders assessed the quality of the websites. From the 208 websites, 104 (50%) provided relevant information about the disability being searched. Of these 104 websites, those found to be of highest quality were least likely to be a sponsored result, contain advertisements, be from a for-profit company, and did contain references to peer-reviewed publications or had a top-level domain of .gov or .org. Individuals with developmental disabilities and their family members who choose to obtain disability-related information online should remain vigilant to ensure that they locate high-quality and accurate information and should not replace information obtained from health-care professionals and educational specialists with information found online.     

Impact of comorbid panic and posttraumatic stress disorder on outcomes of collaborative care for late-life depression in primary care.

OBJECTIVE: Comorbid anxiety disorders may result in worse depression treatment outcomes. The authors evaluated the effect of comorbid panic disorder and posttraumatic stress disorder (PTSD) on response to a collaborative-care intervention for late-life depression in primary care. METHODS: A total of 1,801 older adults with depression were randomized to a collaborative-care depression treatment model versus usual care and assessed at baseline, 3, 6, and 12 months, comparing differences among participants with comorbid panic disorder (N=262) and PTSD (N=191) and those without such comorbid anxiety disorders. RESULTS: At baseline, patients with comorbid anxiety reported higher levels of psychiatric and medical illness, greater functional impairment, and lower quality of life. Participants without comorbid anxiety who received collaborative care had early and lasting improvements in depression compared with those in usual care. Participants with comorbid panic disorder showed similar outcomes, whereas those with comorbid PTSD showed a more delayed response, requiring 12 months of intervention to show a significant effect. At 12 months, however, outcomes were comparable. Interactions of intervention status by comorbid PTSD or panic disorder were not statistically significant, suggesting that the collaborative-care model performed significantly better than usual care in depressed older adults both with and without comorbid anxiety. CONCLUSIONS: Collaborative care is more effective than usual care for depressed older adults with and without comorbid panic disorder and PTSD, although a sustained treatment response was slower to emerge for participants with PTSD. Intensive and prolonged follow-up may be needed for depressed older adults with comorbid PTSD.     

Generalized anxiety disorder in patients with major depression: is DSM-IV's hierarchy correct?

OBJECTIVE: DSM-III imposed a hierarchical relationship in the diagnosis of anxiety disorders in depressed patients, stipulating that anxiety disorders could not be diagnosed if their occurrence was limited to the course of a mood disorder. In the subsequent versions of the DSM this hierarchy was eliminated for all anxiety disorders except generalized anxiety disorder. The authors examined the validity of this remaining hierarchical relationship between mood and anxiety disorders. METHOD: Psychiatric outpatients with major depressive disorder (N=332) were evaluated with a semistructured diagnostic interview and completed paper-and-pencil questionnaires on presentation for treatment. To study the validity of the DSM-IV hierarchical relationship between generalized anxiety disorder and mood disorders, the authors made a diagnosis of modified generalized anxiety disorder for patients with major depressive disorder who met all the criteria for generalized anxiety disorder except for the exclusion criterion. The analyses compared the characteristics of three nonoverlapping groups of patients with DSM-IV major depressive disorder: 1) those with coexisting DSM-IV generalized anxiety disorder, 2) those with coexisting modified generalized anxiety disorder, and 3) those with neither DSM-IV nor modified generalized anxiety disorder. RESULTS: Compared to the depressed patients without generalized anxiety disorder, the depressed patients with DSM-IV and modified generalized anxiety disorder had higher levels of suicidal ideation; poorer social functioning; a greater frequency of other anxiety disorders, eating disorders, and somatoform disorders; higher scores on most subscales of a multidimensional self-report measure of DSM-IV axis I disorders; a greater level of pathological worry; and a higher morbid risk for generalized anxiety disorder in first-degree family members. The two generalized anxiety disorder groups did not differ from each other. CONCLUSIONS: The findings question the validity of the DSM-IV hierarchical relationship between major depressive disorder and generalized anxiety disorder and suggest that the exclusion criterion should be eliminated.     

Psychological interventions for late-life anxiety: a review and early lessons from the CALM study

The authors review the literature on psychological treatment for anxiety in older adults, focusing on randomized, controlled trials. Evidence exists for the efficacy of relaxation training for subjective anxiety symptoms and cognitive-behavioral therapy for generalized anxiety disorder and miscellaneous anxiety syndromes, including panic disorder. The authors also present the rationale for the CALM Study (Controlling Anxiety in Later-life Medical Patients), an ongoing randomized trial in which a modular psychotherapeutic intervention for anxiety in older primary care patients is compared with treatment as usual. Data are presented from 2 pilot patients in the CALM Study, and preliminary lessons are discussed.     

Psychopharmacologic treatment of generalized anxiety disorder and the risk of major depression

OBJECTIVE: The authors sought to determine the association between treatment for generalized anxiety disorder and the risk of major depression among adults in the community. METHOD: Data were drawn from the National Comorbidity Survey (N=8,098), a representative sample of the United States population age 15-54. Cox proportional hazards were used to determine the association between specific forms of treatment for generalized anxiety disorder and the risk of major depression. RESULTS: Psychopharmacologic treatment of generalized anxiety disorder was associated with a significantly lower risk of major depression. There was no significant association between either having seen a mental health professional for generalized anxiety disorder or having been prescribed a medication for generalized anxiety disorder and the risk of depression. CONCLUSIONS: These results suggest an association between treatment for generalized anxiety disorder and lower risk of depression, which appears specific to pharmacologic treatment. Future research that leads to a more precise delineation of the underlying mechanism of the observed association is needed to identify and develop effective strategies to prevent onset of depression.     

Frequency of anxiety disorders in psychiatric outpatients with major depressive disorder

OBJECTIVE: The authors determined the frequency of anxiety disorders in a large group of depressed outpatients seeking treatment. METHOD: The Structured Clinical Interview for DSM-IV was administered to 373 depressed outpatients. RESULTS: More than one-half of the patients met the full criteria for a current anxiety disorder, and more than one-half of the patients with an anxiety disorder had more than one. When partial remissions and anxiety disorder diagnoses classified as "not otherwise specified" were included, two-thirds of the patients had a current anxiety disorder and three-quarters had a lifetime history of an anxiety disorder. CONCLUSIONS: The majority of patients with a principal diagnosis of unipolar major depressive disorder have a comorbid anxiety disorder. Because antidepressant medications have differential efficacies for anxiety disorders, knowledge of the presence of a comorbid anxiety disorder in a depressed patient may have treatment implications.     

Quality of life in individuals with anxiety disorders

OBJECTIVE: Quality-of-life indices have been used in medical practice to estimate the impact of different diseases on functioning and well-being and to compare outcomes between different treatment modalities. An integrated view of the issue of quality of life in patients with anxiety disorders can provide important information regarding the nature and extent of the burden associated with these disorders and may be useful in the development of strategies to deal with it. METHOD: A review of epidemiological and clinical studies that have investigated quality of life (broadly conceptualized) in patients with panic disorder, social phobia, posttraumatic stress disorder, generalized anxiety disorder, and obsessive-compulsive disorder was conducted by searching MEDLINE and PsycLIT citations from 1984 to 1999. A summary of the key articles published in this area is presented. RESULTS: The studies reviewed portray an almost uniform picture of anxiety disorders as illnesses that markedly compromise quality of life and psychosocial functioning. Significant impairment can also be found in individuals with subthreshold forms of anxiety disorders. Effective pharmacological or psychotherapeutic treatment has been shown to improve the quality of life for patients with panic disorder, social phobia, and posttraumatic stress disorder. Limitations in current knowledge in this area are identified, and suggestions for needed future research are provided. CONCLUSIONS: It is expected that a more thorough understanding of the impact on quality of life will lead to increased public awareness of anxiety disorders as serious mental disorders worthy of further investment in research, prevention, and treatment.     

Quality of life impairment in generalized anxiety disorder, social phobia, and panic disorder

Interest in the assessment of quality of life in the anxiety disorders is growing. The present study examined quality of life impairments in individuals with generalized anxiety disorder (GAD), social phobia, and panic disorder. Results showed that individuals with these disorders reported less satisfaction with their quality of life than non-anxious adults in the community. However, the degree of quality of life impairment is similar across these three disorders. Additionally, comorbid depression, but not anxiety, was found to negatively impact quality of life in these individuals. Finally, diagnostic symptom severity was not found to influence quality of life, indicating that subjective measures of quality of life offer unique information on the effects of anxiety disorders.
