Over-diagnosed and over-treated: a survey of Australian public attitudes towards the acceptability of drug treatment for depression and ADHD

Stigma Related to Observable Symptoms, But Not Stimulant Medication Use, in Young Women With ADHD

OBJECTIVE

ADHD is associated with stigma, but whether stimulant medication use contributes to this is unknown. We examined how perception of a young woman may be influenced by visible ADHD symptoms and/or prescribed stimulant medication use (PSMU).

METHOD

Three-hundred-fourteen undergraduates were randomly assigned to watch one of four videos: a woman portraying (a) neither symptoms of ADHD nor PSMU, (b) no ADHD symptoms but disclosing PSMU, (c) ADHD symptoms but no PSMU, or (d) both ADHD symptoms and PSMU. Participants then completed measures of their liking of and desire for affiliation with the woman.

RESULTS

Analyses suggest that visible symptoms of ADHD were perceived negatively and are associated with less liking and desire for affiliation. PSMU was associated with negligible additive stigma.

CONCLUSION

This supports that noticeable ADHD symptoms may be the primary driver of the stigma associated with the disorder, and specifically that directed at young women with ADHD.

Sociodemographic Disparities in Attention-Deficit/Hyperactivity Disorder Overdiagnosis and Overtreatment During Elementary School

Attention-deficit/hyperactivity disorder (ADHD) overdiagnosis and overtreatment unnecessarily exposes children to potential harm and contributes to provider and community skepticism toward those with moderate or severe symptoms and significant impairments, resulting in less supportive care. Yet, which sociodemographic groups of children are overdiagnosed and overtreated for ADHD is poorly understood. We conducted descriptive and logistic regression analyses of a population-based subsample of 1,070 U.S. elementary schoolchildren who had displayed above-average levels of independently assessed behavioral, academic, or executive functioning the year prior to their initial ADHD diagnoses and who did not have prior diagnostic histories. Among these children, (a) 27% of White children versus 19% of non-White children were later diagnosed with ADHD and (b) 20% of White children versus 14% of non-White children were later using medication. In adjusted analyses, White children are more likely to later be diagnosed (odds ratio [OR] range = 1.70-2.62) and using medication (OR range = 1.70-2.37) among those whose prior behavioral, academic, and executive functioning suggested that they were unlikely to have ADHD.

A needs assessment for self-management services for adults awaiting community-based mental health services

BACKGROUND

High demand for services has resulted in lengthy waiting times being experienced across mental health services, both across Australia and internationally. Timely access to services is necessary to optimise the effectiveness of treatment, and prevent further mental health decline, risk of suicidality and hospitalisation for clients waiting for services to commence. The present study aims to better understand the experiences of individuals who are waiting for ongoing mental health services to commence and their preferences for additional support whilst on the waitlist, as a means to recommend alternative supports.

METHODS

A link to the cross-sectional, anonymous survey was sent via text message to 2,147 clients of a mental health service, with a reminder text message sent approximately one week subsequent to those who did not opt out of the communication. Eligibility criteria included having been a client of the service in the previous 12 months, having spent time on the waiting list, being aged 16 or over and having sufficient English proficiency.

RESULTS

A total of 334 participants responded to the needs assessment survey, 277 (82.9%) of which resided in the metropolitan region and 57 (17.1%) residing in the country region. Of the respondents, the majority presented with generalised anxiety/panic attacks (n = 205, 61.4%), followed by life stressors (e.g., financial concerns, relationships, n = 196, 58.7%) and lack of motivation/loss of interest (n = 196, 58.7%). Most respondents (52.7%) waited 4-12 months for ongoing services to commence and almost half (47%) reported that their mental health deteriorated during this time. Of the additional support options, most participants expressed interest in additional mental health supports (78.4%, n = 262), such as telephone support and access to online materials. There was significant interest in other supports such as exercise support (57.4%, n = 192), sleep education (56.6%, n = 190) and healthy eating support (41%, n = 137).

CONCLUSION

Mental health services are experiencing significant waiting times, increasing the risk of mental health deterioration for persons waiting for services to commence. However, the findings demonstrate that there is interest for alternative support options, such as lifestyle interventions, in the interim. Desire for lifestyle support services, particularly in-person exercise programs and self-directed sleep, was especially high amongst the population of respondents within this study. Future work to rigorously develop and evaluate such lifestyle support services for mental health clients is warranted.

Heterogeneity in major depressive disorder: The need for biomarker-based personalized treatments

Major Depressive Disorder (MDD) or depression is a pathological mental condition affecting millions of people worldwide. Identification of objective biological markers of depression can provide for a better diagnostic and intervention criteria; ultimately aiding to reduce its socioeconomic health burden. This review provides a comprehensive insight into the major biomarker candidates that have been implicated in depression neurobiology. The key biomarker categories are covered across all the "omics" levels. At the epigenomic level, DNA-methylation, non-coding RNA and histone-modifications have been discussed in relation to depression. The proteomics system shows great promise with inflammatory markers as well as growth factors and neurobiological alterations within the endocannabinoid system. Characteristic lipids implicated in depression together with the endocrine system are reviewed under the metabolomics section. The chapter also examines the novel biomarkers for depression that have been proposed by studies in the microbiome. Depression affects individuals differentially and explicit biomarkers identified by robust research criteria may pave the way for better diagnosis, intervention, treatment, and prediction of treatment response.

Recent Attitudes toward ADHD in the Broader Community: A Systematic Review

OBJECTIVE

This review aimed to understand the broader community's attitudes toward ADHD, which could facilitate public health interventions to improve outcomes for individuals with ADHD.

METHODS

A standardized protocol identified peer-reviewed studies focusing on attitudes of broader community samples, published from January 2014 to February 2020 (inclusive).

RESULTS

A total of 1,318 articles were screened and 10 studies were included, examining attitudes of broader community samples from Australia, Sweden, Germany, Finland, Korea, Indonesia, and the United States. Findings revealed that broader community samples displayed varying degrees of ADHD-related knowledge, negative attitudes (that ADHD is over-diagnosed; that pharmacological treatment is not acceptable; that those with ADHD are more likely to exhibit poor behavior), and a desire for maintaining social distance from individuals with ADHD.

CONCLUSION

Findings suggest that community attitudes are generally negative toward those with ADHD. Targeted mental health literacy could provide an important avenue for improving the broader community's attitudes toward those with ADHD.

Effects of Meranzin Hydrate On the LncRNA-miRNA-mRNA Regulatory Network in the Hippocampus of a Rat Model of Depression

Meranzin hydrate (MH) is a frequently used antidepressant drug in China; however it underlying mechanism remains unknown. In this study, we aimed to explore whether MH could ameliorate depression-like behavior in rats by regulating the competitive endogenous RNA (ceRNA) network. We developed a depression-like rat model using an unpredictable chronic mild stress (UCMS) protocol, and the differentially expressed lncRNAs, miRNAs, and mRNAs were identified between the model group and MH group. Then, a ceRNA network responding to MH treatment was constructed by their corresponding relationships in the databases. Finally, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were conducted to explore molecular mechanisms associated with MH treatment. The study indicated that rats in the model group showed loss of weight and deteriorated behavior in behavior tests compared with rats in the normal group. A total of 826 lncRNAs, 121 miRNAs, and 954 mRNAs were differentially expressed in the hippocampus of UCMS rats after MH treatment. In addition, 13 miRNAs were selected, and 12 of them were validated in the hippocampus by qRT-PCR. Then, we predicted upstream lncRNAs and downstream mRNAs of the validated miRNAs and interacted with the results of microarrays. Eventually, a lncRNA-miRNA-mRNA regulatory network, responding to MH treatment, was constructed based on the 314 lncRNAs, 11 miRNAs, and 221 mRNAs. KEGG pathways suggested that these genes may be highly related to Wnt signaling, axon guidance, and MAPK signaling pathways. All these results suggest that MH may be a potential representative compound for the treatment of depression, and its mechanism of action is related to the ceRNA modification.

How do people understand overtesting and overdiagnosis? Systematic review and meta-synthesis of qualitative research

RATIONALE

The public should be informed about overtesting and overdiagnosis. Diverse qualitative studies have examined public understandings of this information. A synthesis was needed to systematise the body of evidence and yield new, generalisable insights.

AIM

Synthesise data from qualitative studies exploring patient and public understanding of overtesting and overdiagnosis.

METHODS

We searched Scopus, CINAHL, Ovid MEDLINE and PsycINFO databases from inception to March 18, 2020. We included published English-language primary studies exploring the perspectives of patients/the public about overtesting/overdiagnosis from any setting, year and relating to any condition. Only qualitative parts of mixed-methods studies were synthesised. We excluded studies that only examined overtreatment or sampled people with specialised medical knowledge. Two authors independently selected studies, extracted data, assessed the methodological quality of included studies using the CASP tool, and assessed confidence in the synthesis findings using the GRADE-CERQual approach. Data was analysed using thematic meta-synthesis, utilising descriptive and interpretive methods.

RESULTS

We synthesised data from 21 studies, comprising 1638 participants, from 2754 unique records identified. We identified six descriptive themes, all graded as moderate confidence (indicating they are likely to reasonably represent the available evidence): i) high confidence in screening and testing; ii) difficulty in understanding overuse; iii) acceptance that overuse can be harmful; iv) rejection or problematisation of overuse; v) limited impacts of overuse information on intended test and screening uptake; vi) desire for information and shared decision-making regarding overuse. The descriptive themes were underpinned by two analytic themes: i) perceived intrinsic value of information and information gathering, and; ii) differences in comprehension and acceptance of overuse concepts.

CONCLUSIONS

This study identified novel and important insights about how lay people interpret overuse concepts. It will guide the development of more effective public messages about overuse, highlighting the importance of interpretative frameworks in these communications.

Attention Deficit Hyperactivity Disorder in Children and Adults: A Population Survey on Public Beliefs

Objective: To investigate beliefs and attitudes of the public toward attention deficit hyperactivity disorder (ADHD) in children and adults. Method: In a representative population survey in Germany (N = 1,008) using computer-assisted telephone interviews, we asked participants about causal beliefs, illness recognition, treatment recommendations, and beliefs about ADHD, presenting an unlabelled vignette of a child or an adult with ADHD. Results: The most frequently endorsed causal beliefs for the depicted child with ADHD were "TV or Internet," "lack of parental affection," and "broken home." In comparison with the child vignette, biological causal beliefs were endorsed more often after the adult vignette. In the child vignette, 66% advised against a treatment with stimulant medication. About 90% of respondents had heard of ADHD. Of those, 20% said they believed ADHD to be not a real disease. Conclusion: Beliefs of the German public partly contradict evidence and should be considered in therapeutical and public contexts.

Guideline adherence in the management of attention deficit hyperactivity disorder in children: An audit of selected medical records in three Australian states

OBJECTIVE

To assess General Practitioner (GP) and pediatrician adherence to clinical practice guidelines (CPGs) for diagnosis, treatment and management of attention deficit hyperactivity disorder (ADHD).

METHOD

Medical records for 306 children aged ≤15 years from 46 GP clinics and 20 pediatric practices in Australia were reviewed against 34 indicators derived from CPG recommendations. At indicator level, adherence was estimated as the percentage of indicators with 'Yes' or 'No' responses for adherence, which were scored 'Yes'. This was done separately for GPs, pediatricians and overall; and weighted to adjust for sampling processes.

RESULTS

Adherence with guidelines was high at 83.6% (95% CI: 77.7-88.5) with pediatricians (90.1%; 95% CI: 73.0-98.1) higher than GPs (68.3%; 95% CI: 46.0-85.8; p = 0.02). Appropriate assessment for children presenting with signs or symptoms of ADHD was undertaken with 95.2% adherence (95% CI: 76.6-99.9), however ongoing reviews for children with ADHD prescribed stimulant medication was markedly lower for both pediatricians (51.1%; 95% CI: 9.6-91.4) and GPs (18.7%; 95% CI: 4.1-45.5).

CONCLUSION

Adherence to CPGs for ADHD by pediatricians was generally high. Adherence by GPs was lower across most domains; timely recognition of medication side effects is a particular area for improvement.

Parent-perceived barriers to accessing services for their child's mental health problems

BACKGROUND

Many children and adolescents with impairing mental health disorders are not in contact with specialized child and adolescent mental health services (CAMHS). In order to close the service gap, it is important to increase our knowledge of barriers to access. The aim of this study was to investigate parent perceived barriers to accessing services for their child's mental health problems to identify potential areas for improvement of access to CAMHS.

METHOD

In this cross-sectional observational study 244 parents of children and adolescents referred to outpatient psychiatric assessment were interviewed using the Children's services interview regarding barriers to accessing child mental health services across healthcare, educational services and social services. Parent reported barriers were analyzed in relation to the child's age, referral reason, symptom duration and impairment of the child.

RESULTS

The most commonly reported barriers were lack of information about were to seek help (60.3%), the perception that professionals did not listen (59.8%) and professionals refusing to initiate interventions or provide referral to services (53.7%). Lack of knowledge, stigmatization and unavailability of services were common themes across barriers to help-seeking. Long symptom duration and parent rated impairment was associated with increased risk of reporting several barriers to help-seeking.

CONCLUSION

Parents seeking help for their child's mental health encounter numerous barriers that could explain part of the treatment gap and long duration of mental health problems in children prior to referral to CAMHS.

Perceptions and Attitudes of Correctional Staff Toward ADHD-A Challenging Disorder in Everyday Prison Life

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder that is associated with risk-taking behaviors, poor self-control, and interpersonal difficulties. Affected individuals have an increased probability of involvement with the criminal justice system, contributing to a higher rate of arrest, and imprisonment compared with the general population; they are also inadequately treated once sentenced. Because prison staff play a central role in the identification of inmates with mental disorders, they could well be key to improving provision of care. There is however little knowledge of the conceptions, perceptions, and attitudes of prison staff toward ADHD. Such information could help to identify starting points for awareness training and further implementation of specific ADHD treatment. To bridge this gap, we undertook a study based on a qualitatively-driven mixed methods design, combining qualitative data collection in the form of narrative interviews with 19 prison staff from a Swiss correctional facility with quantitative data collection in the form of a survey that included the Attitudes toward Prisoners scale. The interviews were analyzed with QSR NVIVO 11 and a qualitative content analysis approach was used to evaluate findings. Prison staff were generally aware of ADHD and its symptomology, believing it to a be "real," but "fashionable" disorder and favoring hereditary-genetic or biological explanatory models for its development. They viewed inmates with ADHD rather negatively, as complicating correctional efforts, and perceived them as sticking out, as tying up more resources and as frequently being involved in confrontations. Our findings suggest that difficulties in pragmatic aspects of communication and language comprehension may be perceived "as not listening or following instructions," creating additional tensions. Consequently, inmates with ADHD are more often exposed to disciplinary sanctions, such as solitary confinement-an intervention deemed "necessary" by staff. Therefore, staff training on ADHD might need to cover evidence on adverse effects. Non-pharmacological interventions for treatment were preferred and considered to be highly efficacious. Skepticism toward pharmacological treatment prevailed, even when benefits from stimulant medication were described. Interestingly, this skepticism was not the result of negative experiences with the misuse and diversion of stimulants. Acceptance of multimodal treatment among prison staff may require customized strategies.

Antidepressant use in Australia and Sweden-A cross-country comparison

PURPOSE

To compare the dispensed use of antidepressants in Australia and Sweden.

METHODS

We analysed publicly available data from Australia and Sweden on dispensed use of antidepressants from 2006 to 2018.

RESULTS

The dispensed use of antidepressants has increased in both Australia and Sweden. Australia had a more rapid increase resulting in a higher total use. The utilisation profile was similar in both countries; SSRIs were the most commonly used group, "other antidepressants" were the group that increased the most, and seven of the eight most used substances were the same. There were differences in which antidepressants were most used, with the three most prescribed antidepressants being escitalopram, sertraline, and venlafaxine in Australia; and mirtazapine, sertraline, and citalopram in Sweden.

CONCLUSION

Dispensed use of antidepressants has increased remarkably in both Australia and Sweden between 2006 and 2018. Although similar with regard to economic status and health care system, use of antidepressants differs between both countries. This may be a result of a combination of factors related to medical, contextual and policy evidence. The differences displayed in this study may reflect varying accessibility of treatments, national programmes enhancing mental health literacy in the population, clinical prescribing guidelines and timing of approval of new antidepressants.

SDQ Dysregulation Profile and Its Relation to the Severity of Psychopathology and Psychosocial Functioning in a Sample of Children and Adolescents With ADHD

Objective: A substantial number of children and adolescents with ADHD show severe affective and behavioral dysregulation. A dysregulation profile (DP) distinguishes those participants at a higher risk of comorbidity, dysfunction, and a poorer response to treatment. It was identified as high scoring in certain subscales of the Strengths and Difficulties Questionnaire (SDQ-DP). We developed a cross-sectional study to assess the clinical utility of the SDQ-DP in ADHD. Method: Two hundred fifty clinic-referred children and adolescents with ADHD were assessed. Univariate and linear regression analyses were performed to compare those participants with high levels of SDQ-DP with those with low levels, as well as to examine the association between the SDQ-DP and clinical variables. Results: In all, 28% of ADHD participants had high levels of SDQ-DP. These participants showed higher functional impairment and clinical severity. Conclusion: The use of the SDQ-DP will enable identification of those ADHD patients at greater risk.

In transition with ADHD: the role of information, in facilitating or impeding young people's transition into adult services

BACKGROUND

Many national and regional clinical guidelines emphasise the need for good communication of information to young people and their parent/carers about what to expect during transition into adult services. Recent research indicates only a minority of young people in need of transition for Attention Deficit Hyperactivity Disorder (ADHD) experience continuity of care into adulthood, with additional concerns about quality of transition. This qualitative study explored the role that information plays in experiences of transition from the perspectives of parent/carers and young people.

METHODS

Participants were recruited from 10 National Health Service Trusts, located across England, with varying service configurations. Ninety two qualitative interviews were conducted: 64 with young people with ADHD at different stages relative to transition, and 28 with parent/carers. Thematic analysis of data was completed using the Framework Method.

RESULTS

Interviewees reported a range of experiences; however reliance on parent/carers to gather and translate key information, and negative experiences associated with poor communication of information, were universal. Three themes emerged: Navigating information with help from parents; Information on ADHD into adulthood; Information about the transition process. The first revealed the essential role of parent in the translation and application of information, the other two explored distinct types of information necessary for a smooth transition. Interviewees made recommendations for clinical practice similar to UK (United Kingdom) National Institute for Health and Care Excellence (NICE) guidelines, with an additional emphasis on providing nuanced information on ADHD as a potentially long term condition. It was important to interviewees that General Practitioners had a basic understanding of adult ADHD and also had access to information about service provision.

CONCLUSIONS

Our findings illustrate that the availability and communication of information to young people and their parent/carers is an essential component of the transition process between child and adult ADHD services. How and when it is provided may support or impede transition. This study constitutes a substantial contribution to the evidence base, drawing on interviews from a range of participants across England and from Trusts offering different types of services.

Defining and Evaluating Overdiagnosis in Mental Health: A Meta-Research Review

BACKGROUND

Overdiagnosis is thought to be common in some mental disorders, but it has not been defined or examined systematically. Assessing overdiagnosis in mental health requires a consistently applied definition that differentiates overdiagnosis from other problems (e.g., misdiagnosis), as well as methods for quantification.

OBJECTIVES

Our objectives were to (1) describe how the term "overdiagnosis" has been defined explicitly or implicitly in published articles on mental disorders, including usages consistent (overdefinition, overdetection) and inconsistent (misdiagnosis, false-positive test results, overtreatment, overtesting) with accepted definitions of overdiagnosis; and (2) identify examples of attempts to quantify overdiagnosis.

METHOD

We searchedPubMed through January 5, 2019. Articles on mental disorders, excluding neurocognitive disorders, were eligible if they usedthe term "overdiagnosis" in the title, abstract, or text.

RESULTS

We identified 164 eligible articles with 193 total explicit or implicit uses of the term "overdiagnosis." Of 9 articles with an explicit definition, only one provided a definition that was partially consistent with accepted definitions. Of all uses, 11.4% were consistent, and 76.7% were related to misdiagnosis and thus inconsistent. No attempts to quantify the proportion of patients who were overdiagnosed based on overdetection or overdefinition were identified.

CONCLUSIONS

There are few examples of mental health articles that describe overdiagnosis consistent with accepted definitions and no examples of quantifying overdiagnosis based on these definitions. A definition of overdiagnosis based on diagnostic criteria that include people with transient or mild symptoms not amenable to treatment (overdefinition) could be used to quantify the extent of overdiagnosis in mental disorders.

Neurofeedback versus psychostimulants in the treatment of children and adolescents with attention-deficit/hyperactivity disorder: a systematic review

This systematic review aimed to evaluate the efficacy of neurofeedback (NF) compared to stimulant medication in treating children and adolescents with attention-deficit/hyperactivity disorder (ADHD). Included in this review are eight randomized controlled trials that compared an NF condition, either alone or combined with medication, to a medication condition, which was mainly methylphenidate. Outcome measures included behavioral assessments by parents and teachers, self-reports, neurocognitive measures, electroencephalogram power spectra and event-related potentials. When only trials are considered that include probably blinded ratings or those that are sham-NF or semi-active controlled or those that employed optimally titration procedures, the findings do not support theta/beta NF as a standalone treatment for children or adolescents with ADHD. Nevertheless, an additive treatment effect of NF was observed on top of stimulants and theta/beta NF was able to decrease medication dosages, and both results were maintained at 6-month follow-up. This review concludes that the present role of NF in treating children diagnosed with ADHD should be considered as complementary in a multimodal treatment approach, individualized to the needs of the child, and may be considered a viable alternative to stimulants for a specific group of patients. Particularly patients with the following characteristics may benefit from NF treatment: low responders to medication, intolerable side effects due to medication, higher baseline theta power spectra and possibly having no comorbid psychiatric disorders. Future research should prioritize the identification of markers that differentiate responders from nonresponders to NF treatment, the potential of NF to decrease stimulant dosage, the standardization of NF treatment protocols and the identification of the most favorable neurophysiological treatment targets.

Prevalence rates of youths diagnosed with and medicated for ADHD in a nationwide survey in Taiwan from 2000 to 2011

AIMS

Public controversy regarding the potential overdiagnosis and overmedication of children with attention-deficit/hyperactivity disorder (ADHD) has continued for decades. This study used the National Health Insurance Research Database of Taiwan (NHIRD-TW) to explore trends in ADHD diagnosis in youths and the proportion of those receiving medication, with the aim of determining whether ADHD is overdiagnosed and overmedicated in Taiwan.

METHOD

Youths (age ≤18 years) who had at least two NHIRD-TW claims records with ADHD diagnosis between January 2000 and December 2011 were selected as the subject cohort. In total, the study sample comprised 145 018 patients with ADHD (mean age at a diagnosis of ADHD: 7.7 ± 3.1 years; 21.4% females). The number of cases of ADHD were calculated annually for each year (from 2000 to 2011), and the number of cases per year who received medication was determined as those with at least one record of pharmacotherapy (immediate-release methylphenidate, osmotic controlled-release formulation of methylphenidate, and atomoxetine) in each year.

RESULTS

The prevalence rates of a diagnosis of ADHD in the youths ranged from 0.11% in 2000 to 1.24% in 2011. Compared with children under 6 years of age, the ADHD diagnosis rates in children aged between 7 and 12 years (ratio of prevalence rates = 4.36) and in those aged between 13 and 18 years (ratio of prevalence rates = 1.42) were significantly higher during the study period. The prevalence in males was higher than that in females (ratio of prevalence rates = 4.09). Among the youths with ADHD, 50.2% received medications in 2000 compared with 61.0% in 2011. The probability of receiving ADHD medication increased with age. More male ADHD patients received medications that females patients (ratio of prevalence rates = 1.16).

CONCLUSIONS

The rate of ADHD diagnosis was far lower than the prevalence rate (7.5%) identified in a previous community study using face-to-face interviews. Approximately 40-50% of the youths with ADHD did not receive any medications. These findings are not consistent with a systematic public opinion about overdiagnosis or overmedication of ADHD in Taiwan.

Identifying cross-cultural variations in psychostimulant use for attention deficit hyperactivity disorder using linked data

BACKGROUND

To validate the association between country-of-birth and disparities in the stimulant use for ADHD among individuals in Western Australia.

METHODS

Using linked data, a population-based retrospective cohort of individuals admitted to hospital before age 25 years was followed through to identify having stimulants for ADHD in 2003-2007. Multivariate logistic and linear regressions were used to characterise associations between stimulants and country-of-birth, geographical remoteness and socioeconomic status.

RESULTS

Of 679,645 individuals, 14,122 (2.1%) had a record of having stimulants for ADHD. Of these, 205 (1.5%) were born in Africa, Asia, Middle-East or South America, while 13,664 (96.8%) were born in Australia/New Zealand, Europe or North America. Individuals with traditionally non-Anglophonic backgrounds were around one-half as likely to have stimulants as individuals with Anglophonic backgrounds (OR = 0.53, 95% CI 0.46-0.61, p < 0.001). Non-Anglophones were an average of 2.7 years older than Anglophones at onset of having stimulants. Individuals from remote and disadvantaged backgrounds had stimulants at younger ages than individuals living in metropolitan areas and with least disadvantage.

CONCLUSIONS

The results highlight the importance of identifying factors underlying cultural differences in stimulant treatment for ADHD. Improving awareness of cultural variations may foster trust and rapport between patients and clinicians, and so better facilitate the appropriate and effective treatment of ADHD for each patient.

Public attitudes towards psychiatry and psychiatric treatment at the beginning of the 21st century: a systematic review and meta-analysis of population surveys

Public attitudes towards psychiatry are crucial determinants of help-seeking for mental illness. It has been argued that psychiatry as a discipline enjoys low esteem among the public, and a "crisis" of psychiatry has been noted. We conducted a systematic review and meta-analysis of population studies examining public attitudes towards various aspects of psychiatric care. Our search in PubMed, Web of Science, PsychINFO and bibliographies yielded 162 papers based on population surveys conducted since 2000 and published no later than 2015. We found that professional help for mental disorders generally enjoys high esteem. While general practitioners are the preferred source of help for depression, mental health professionals are the most trusted helpers for schizophrenia. If respondents have to rank sources of help, they tend to favor mental health professionals, while open questions yield results more favorable to general practitioners. Psychiatrists and psychologists/psychotherapists are equally recommended for the treatment of schizophrenia, while for depression psychologists/psychotherapists are more recommended, at least in Europe and America. Psychotherapy is consistently preferred over medication. Attitudes towards seeking help from psychiatrists or psychologists/psychotherapists as well as towards medication and psychotherapy have markedly improved over the last twenty-five years. Biological concepts of mental illness are associated with stronger approval of psychiatric help, particularly medication. Self-stigma and negative attitudes towards persons with mental illness decrease the likelihood of personally considering psychiatric help. In conclusion, the public readily recommends psychiatric help for the treatment of mental disorders. Psychotherapy is the most popular method of psychiatric treatment. A useful strategy to further improve the public image of psychiatry could be to stress that listening and understanding are at the core of psychiatric care.

Integrating care for neurodevelopmental disorders by unpacking control: A grounded theory study

BACKGROUND

To establish integrated healthcare pathways for patients with neurodevelopmental disorders (ND) such as autism spectrum disorder and attention-deficit hyperactivity disorder is challenging. This study sets out to investigate the main concerns for healthcare professionals when integrating ND care pathways and how they resolve these concerns.

METHODS

Using classic grounded theory (Glaser), we analysed efforts to improve and integrate an ND care pathway for children and youth in a Swedish region over a period of 6 years. Data from 42 individual interviews with a range of ND professionals, nine group interviews with healthcare teams, participant observation, a 2-day dialogue conference, focus group meetings, regional media coverage, and reports from other Swedish regional ND projects were analysed.

RESULTS

The main concern for participants was to deal with overwhelming ND complexity by unpacking control, which is control over strategies to define patients' status and needs. Unpacking control is key to the professionals' strivings to expand constructive life space for patients, to squeeze health care to reach available care goals, to promote professional ideologies, and to uphold workplace integrity. Control-seeking behaviour in relation to ND unpacking is ubiquitous and complicates integration of ND care pathways.

CONCLUSIONS

The Unpacking control theory expands central aspects of professions theory and may help to improve ND care development.

"It has to be fixed": a qualitative inquiry into perceived ADHD behaviour among affected individuals and parents in Western Australia

BACKGROUND

The use of stimulant medication for Attention Deficit Hyperactivity Disorder (ADHD) to improve classroom behaviour and sustained concentration is well known. Achieving a better academic grade has been reported as the prime motivation for stimulant use and is an increasingly discussed topic. The proliferation of stimulant use for ADHD has been a cause for public, medical and policy concern in Australia. This paper explores individuals' perceptions of ADHD, the meaning that the diagnosis carries for them and their attitudes to stimulant medication treatment.

METHODS

This qualitative study was underpinned by a social constructivist approach and involved semi-structured interviews with eight participants. The participants were parents of children with ADHD or were adults who themselves had been diagnosed with ADHD. Interviews were audiotaped, transcribed verbatim and thematically analysed.

RESULTS

There were three interrelated yet contradictory overarching themes: (i) An impairment to achieving success, which can be a double-edged sword, but has to be fixed; (ii) Diagnosis as a relief that alleviates fault and acknowledges familial inheritance; (iii) Responsibility to be normal and to fit in with societal expectations. Collectively, these perceptions and meanings were powerful drivers of stimulant use.

CONCLUSIONS

Paying attention to perceptions of ADHD and reasons for seeking or not seeking stimulant treatment is important when planning appropriate interventions for this condition.

Effects of duloxetine on microRNA expression profile in frontal lobe and hippocampus in a mouse model of depression

Depression is a major mood disorder affecting people worldwide. The posttranscriptional gene regulation mediated by microRNAs (miRNAs) which may have critical roles in the pathogenesis of depression. However, to date, little is known about the effects of the antidepressant drug duloxetine on miRNA expression profile in chronic unpredictable mild stress (CUMS)-induced depression model in mice. Healthy adult male Kunming mice were randomly divided into three groups: control group, model group and duloxetine group. Sucrose preference test and open field test were used to represent the behavioral change. MiRNAs levels in frontal lobe and hippocampus of mice were analyzed using miRNA microarrays assay. We observed that long-term treatment with duloxetine significantly ameliorated the CUMS procedure-induced sucrose preference decreases and mice treated with duloxetine demonstrated a reversal of the number of crossings, and rearings reduced by CUMS. A significant upregulation of miR-132 and miR-18a in hippocampus in the duloxetine treatment group compared with model group, whereas the levels of miR-134 and miR-124a were significantly downregulated. Furthermore, miR-18a showed significant upregulation in frontal lobe in the duloxetine treatment group relative to model group. Our data showed that miRNA expression profile in frontal lobe and hippocampus was affected by duloxetine in mice model of depression. The effect was especially pronounced in the hippocampus, suggesting that hippocampus might be the action site of duloxetine, which presumably worked by regulating the expression of miRNA levels.

Unmet needs in paediatric psychopharmacology: Present scenario and future perspectives

Paediatric psychopharmacology holds great promise in two equally important areas of enormous biomedical and social impact, namely the treatment of behavioural abnormalities in children and adolescents, and the prevention of psychiatric disorders with adolescent- or adult-onset. Yet, in striking contrast, pharmacological treatment options presently available in child and adolescent psychiatry are dramatically limited. The most important currently unmet needs in paediatric psychopharmacology are: the frequent off-label prescription of medications to children and adolescents based exclusively on data from randomized controlled studies involving adult patients; the frequent lack of age-specific dose, long-term efficacy and tolerability/safety data; the lack of effective medications for many paediatric psychiatric disorders, most critically autism spectrum disorder; the scarcity and limitations of randomized placebo-controlled trials in paediatric psychopharmacology; the unexplored potential for the prevention of psychiatric disorders with adolescent- and adult-onset; the current lack of biomarkers to predict treatment response and severe adverse effects; the need for better preclinical data to foster the successful development of novel drug therapies; and the effective dissemination of evidence-based treatments to the general public, to better inform patients and families of the benefits and risks of pharmacological interventions during development. Priorities and strategies are proposed to overcome some of these limitations, including the European Child and Adolescent Clinical Psychopharmacology Network, as an overarching Pan-European infrastructure aimed at reliably carrying out much needed psychopharmacological trials in children and adolescents, in order to fill the identified gaps and improve overall outcomes.

Prevalence of attention-deficit/hyperactivity disorder: a systematic review and meta-analysis

BACKGROUND AND OBJECTIVE

Overdiagnosis and underdiagnosis of attention-deficit/hyperactivity disorder (ADHD) are widely debated, fueled by variations in prevalence estimates across countries, time, and broadening diagnostic criteria. We conducted a meta-analysis to: establish a benchmark pooled prevalence for ADHD; examine whether estimates have increased with publication of different editions of the Diagnostic and Statistical Manual of Mental Disorders (DSM); and explore the effect of study features on prevalence.

METHODS

Medline, PsycINFO, CINAHL, Embase, and Web of Science were searched for studies with point prevalence estimates of ADHD. We included studies of children that used the diagnostic criteria from DSM-III, DSM-III-R and DSM-IV in any language. Data were extracted on sampling procedure, sample characteristics, assessors, measures, and whether full or partial criteria were met.

RESULTS

The 175 eligible studies included 179 ADHD prevalence estimates with an overall pooled estimate of 7.2% (95% confidence interval: 6.7 to 7.8), and no statistically significant difference between DSM editions. In multivariable analyses, prevalence estimates for ADHD were lower when using the revised third edition of the DSM compared with the fourth edition (P = .03) and when studies were conducted in Europe compared with North America (P = .04). Few studies used population sampling with random selection. Most were from single towns or regions, thus limiting generalizability.

CONCLUSIONS

Our review provides a benchmark prevalence estimate for ADHD. If population estimates of ADHD diagnoses exceed our estimate, then overdiagnosis may have occurred for some children. If fewer, then underdiagnosis may have occurred.

Managing the risks of ADHD treatments

Pharmacotherapy of attention deficit-hyperactivity disorder (ADHD) is a well-established and effective treatment modality. However, ADHD medications are not without side effects. Understanding the prevalence of adverse events and effective management of risks associated with stimulants and other medications used to treat ADHD is central to broad applicability and effective treatment. This review discusses the literature on the prevalence of adverse events and management strategies employed. We searched online MEDLINE/PubMed and Cochrane databases for articles using several keywords relating to adverse events associated with ADHD medication management. We discuss the relevant data on the significance and prevalence of side effects and adverse events, highlight recent updates in the field, and suggest approaches to clinical management.
