A randomised controlled feasibility trial of intermittent theta burst stimulation with an open longer-term follow-up for young people with persistent anorexia nervosa (RaISE): Study protocol

OBJECTIVE

We present the protocol of a feasibility randomised controlled trial (RCT) of intermittent theta burst stimulation (iTBS) for young people with anorexia nervosa (AN). Effective first-line psychological therapies exist for young people with AN, but little is known about how to treat those who do not respond. Non-invasive neuromodulation, such as iTBS, could address unmet treatment needs by targeting neurocircuitry associated with the development and/or maintenance of AN.

DESIGN

Sixty-six young people (aged 13-30 years) with persistent AN will be randomly allocated to receive 20 sessions of real or sham iTBS over the left dorsolateral prefrontal cortex in addition to their usual treatment. Outcomes will be measured at baseline, post-treatment (1-month post-randomisation) and 4-months post-randomisation (when unblinding will occur). Additional open follow-ups will be conducted at 12- and 24-months post-randomisation. The primary feasibility outcome is the proportion of participants retained in the study at 4-months. Secondary outcomes include AN symptomatology, other psychopathology, quality of life, service utilisation, neurocognitive processes, and neuroimaging measures.

DISCUSSION

Findings will inform the development of a future large-scale RCT. They will also provide exploratory data on treatment efficacy, and neural and neurocognitive predictors and correlates of treatment response to iTBS in AN.

Avoidant Restrictive Food Intake Disorder (ARFID)-Looking beyond the eating disorder lens?

Avoidant Restrictive Food Intake Disorder (ARFID) was first included as a diagnostic category in 2013, and over the past 10 years has been adopted by the international eating disorder community. While greater awareness of these difficulties has increased identification, demand and enabled advocacy for clinical services, the heterogeneous nature of ARFID poses unique challenges for eating disorder clinicians and researchers. This commentary aims to reflect on some of these challenges, focussing specifically on the risk of viewing ARFID through an eating disorder lens. This includes potential biases in the literature as most recent research has been conducted in specialist child and adolescent eating disorder clinic settings, bringing in to question the generalisability of findings to the broad spectrum of individuals affected by ARFID. We also consider whether viewing ARFID predominantly through an eating disorder lens risks us as a field being blinkered to the range of effective skills our multi-disciplinary feeding colleagues may bring. There are opportunities that may come with the eating disorder field navigating treatment pathways for ARFID, including more joined up working with multi-disciplinary colleagues, the ability to transfer skills used in ARFID treatment to individuals with eating disorder presentations, and most notably an opportunity to provide more effective treatment and service pathways for individuals with ARFID and their families. However, these opportunities will only be realised if eating disorder clinicians and researchers step out of their current silos.

EDIFY (Eating Disorders: Delineating Illness and Recovery Trajectories to Inform Personalised Prevention and Early Intervention in Young People): project outline

EDIFY (Eating Disorders: Delineating Illness and Recovery Trajectories to Inform Personalised Prevention and Early Intervention in Young People) is an ambitious research project aiming to revolutionise how eating disorders are perceived, prevented and treated. Six integrated workstreams will address key questions, including: What are young people's experiences of eating disorders and recovery? What are the unique and shared risk factors in different groups? What helps or hinders recovery? How do the brain and behaviour change from early- to later-stage illness? How can we intervene earlier, quicker and in a more personalised way? This 4-year project, involving over 1000 participants, integrates arts, design and humanities with advanced neurobiological, psychosocial and bioinformatics approaches. Young people with lived experience of eating disorders are at the heart of EDIFY, serving as advisors and co-producers throughout. Ultimately, this work will expand public and professional perceptions of eating disorders, uplift under-represented voices and stimulate much-needed advances in policy and practice.

Family body culture, disordered eating and mental health among young adult females during COVID-19

Different family interactions related to body weight and shape may co-occur and represent a broader 'family body culture'. This may be important in the context of COVID-19 due to a heightened focus on body weight/shape, and many young adults living back with their families. This study aimed to, first, explore relationships between different family body-related interactions to assess the presence of a family body culture, and second, explore relationships between aspects of family body culture, disordered eating and mental health among young adult females during the COVID-19 pandemic. Participants were 233 females aged 18-25 years who completed measures of family body culture (family fat talk; family weight concern; family weight teasing), disordered eating, anxiety and depression. Results showed all aspects of family body culture were significantly, positively related. Engaging in fat talk with family members (self fat talk) was a key correlate of disordered eating, anxiety and depression. Family concern with weight was also significantly associated with disordered eating. Findings suggest that among some families there is a more problematic family body culture with a greater importance placed on body weight and shape through various body-related interactions. Additionally, findings highlight two key aspects of family body culture related to disordered eating and wellbeing among young adult females. Specifically, vocalising critical remarks about one's own body when with family and an environment that may indirectly communicate a high importance of body weight and shape (e.g., via dieting). These should be considered in future family interventions to support healthy eating behaviours.

Management of fraudulent participants in online research: Practical recommendations from a randomized controlled feasibility trial

OBJECTIVE

Fraudulent participation is an escalating concern for online clinical trials and research studies and can have a significant negative impact on findings. We aim to shed light on the risk and to provide practical recommendations for detecting and managing such instances.

METHODS

The FREED-Mobile (FREED-M) study is an online, randomized controlled feasibility trial to assess a digital early intervention for young people (aged 16-25) in England or Wales with eating problems. The trial involved baseline (week 0), post-intervention (week 4), and follow-up (week 12) surveys, alongside weekly modules provided over 4 weeks on the study website. Study completers were compensated with £20 shopping vouchers. Despite the complexity of the trial design, two instances of fraudulent sign-ups occurred in January and March 2023. To counter this, we developed a "fraudulent participants protocol" following internal investigations and discussions with collaborators.

RESULTS

The implementation of prevention measures such as reCAPTCHA updates, IP address review, and changes in reimbursement effectively halted further fraudulent sign-ups. Our protocol facilitated the systematic identification and withdrawal of suspected or clear fraudsters and was demonstrably robust at distinguishing between fraudsters and genuine responders.

DISCUSSION

All remote, online trials or studies are at risk of fraudulent participation. Drawing from our experience and existing literature, we offer practical recommendations for researchers considering online recruitment and data collection. Vigilance and the integration of deterrents, and data quality checks into the study design from the outset are advised to safeguard research integrity.

PUBLIC SIGNIFICANCE

Fraudulent participation in digital research can have asignificant impact on research findings, potentially leading to biased resultsand misinformed decisions. We developed an effective protocol for theprevention, identification, and management of fraudulent participants. Bysharing our insights and recommendations, we hope to raise awareness of thisissue and provide other researchers with the knowledge and strategies necessaryto safeguard research integrity moving forward.

Individuals with restrictive eating disorders' experience of the introduction of calories on menus in England: An interpretative phenomenological analysis study

OBJECTIVE

In April 2022 the Calorie Labelling (Out of Home) Regulations came into effect in England where cafés, restaurants, and takeaways with over 250 employees were required to provide calorie labelling on menus. Concerns have been raised regarding the potential negative impact this could have on individuals with eating disorders (EDs), yet this has not been explored using qualitative methodology.

METHOD

Eleven participants with a current or previously diagnosed restrictive ED were interviewed in September 2022. Interpretative Phenomenological Analysis (IPA) was used to explore their experience of the introduction of calories on menus.

RESULTS

Using IPA we established six themes and seven subordinate themes. These included the introduction of calories on menus as an 'attack' on individuals with EDs; the prominent visual display of calories as an attentional pull; normalising of calories counting; the impact on behaviour; and associated strategies for managing.

CONCLUSION

This contributes to research surrounding the implications for public health policies on individuals with EDs, especially their ability to reinforce and amplify disordered thoughts and behaviours, and the need for greater consideration of how to minimise impact and potential harm of large public health campaigns.

Experiences of inpatient eating disorder admissions: A systematic review and meta-synthesis

OBJECTIVE

There has been a significant increase in the number of inpatient admissions for individuals with eating disorders and, with the most critical cases requiring inpatient treatment, it is essential that we continue to improve associated outcomes. The aim of the study was to synthesise the available qualitative literature on the experiences of inpatient admissions for eating disorders to understand individuals' experiences and identify areas that may require further research and/or service development.

METHOD

Searches were performed on the following online databases: PsycINFO, PsycArticles, PsycTherapy MEDLINE, Embase, CINAHL, ASSIA, Scopus and Proquest Open Access Theses. Only papers with qualitative data regarding individuals' experiences of inpatient eating disorder treatment were considered. The CASP qualitative checklist was used to assess studies and relevant data items were extracted. Thematic synthesis was used to integrate the findings in the identified studies. GRADE-CERQual was used to rate the confidence in the findings.

RESULTS

Twenty-eight studies were identified which the CASP assessment considered to be adequate. The synthesis produced 5 main themes; 'Care and control', 'Inpatient bubble', 'Being supported and understood', 'Challenges of living with others' eating disorders' and finally 'Relationship to eating disorder'. The GRADE CERQual framework rated findings with high or moderate confidence.

CONCLUSIONS

Findings reaffirmed the importance of patient-centred care and the significant impact of being separated from normal life with others also experiencing an eating disorder.

"It's not about wanting to be thin or look small, it's about the way it feels": an IPA analysis of social and sensory differences in autistic and non-autistic individuals with anorexia and their parents

BACKGROUND

Despite increasing evidence to support an overlap between autism and anorexia nervosa (AN), underlying mechanisms remain poorly understood. Social and sensory factors have emerged as promising targets in both autism and AN, however there remains scope to compare these differences across autistic and non-autistic experiences of AN. Drawing on dyadic multi-perspectives, this study explored experiences of social and sensory differences in autistic and non-autistic adults and their parents and/or carers.

METHODS

Using interpretative phenomenological analysis (IPA), dyadic interviews were conducted with 14 dyads, with seven autistic dyads and seven non-autistic dyads. Data analysis was subjected to a triangulation of interpretations: (1) the participants themselves; (2) a neurotypical researcher; (3) and an Autistic researcher with lived/living experience of AN.

RESULTS

IPA identified three themes in each group, with similarities and differences between autistic and non-autistic dyads. Similar themes were identified regarding the importance of social connectedness and socio-emotional difficulties, as well a common lack of trust in the social and sensory self and body. Autism-specific themes centred on feelings of social 'defectiveness', disparities between sensing and expressing certain cues, and lifelong, multi-sensory processing differences. Non-autistic themes reflected social comparisons and inadequacy, and sensitivities to the learning of ideals and behaviour through early experiences.

CONCLUSIONS

While similarities were observed across both groups, there appeared to be notable differences in the perceived role and influence of social and sensory differences. These findings may have important implications on the delivery and modification of eating disorder interventions. Specifically, they suggest that while treatment targets may look similar, subtle differences in underlying mechanisms and approaches may be required for Autistic individuals with AN across sensory, emotion and communication-based interventions.

A UK-wide survey of healthcare professionals' awareness, knowledge and skills of the impact of food insecurity on eating disorder treatment

OBJECTIVE

Food insecurity (FI) is associated with significant adverse effects on health and well-being and increasingly recognised as a global problem. The current study explored the impact of FI on eating disorder (ED) clinical practice in the UK, aiming to assess healthcare professionals' (HCPs) knowledge, skills and views on the topic of FI in their patients.

DESIGN

This study was an exploratory, mixed-methods, descriptive analysis of online survey data collected from ED HCPs in the UK between September and October 2022.

MEASURES

A 15-item survey with rating and open-ended questions was circulated to ED professional organisations in the UK. Descriptive statistics were used to summarise quantitative data, including perceived prevalence of FI in ED clinical practice and confidence in knowledge on the topic. Descriptive content analyses provided insight into perspectives on FI screening and aspects to be included in guidance and resources.

RESULTS

93 ED HCPs completed the survey (40.9 % psychologists). Findings demonstrated healthcare providers' limited knowledge on FI and its relation to EDs, while they increasingly perceive it in their patients, as well as a general lack of available resources on how to address FI in ED treatment. HCPs stressed the need for practical guidance and formal training for dealing with FI in their patients, as well as implementing routine screening.

CONCLUSION

These findings provide both important directions for future research and clinical applications related to screening, assessment, treatment and support of food-insecure patients with EDs.

Review: Can digital mental health interventions bridge the 'digital divide' for socioeconomically and digitally marginalised youth? A systematic review

BACKGROUND

Digital mental health interventions (DMHIs) have the potential to improve the efficiency, accessibility and effectiveness of mental health services for young people, with the potential to reach socioeconomically and digitally marginalised young people with mental health needs who would otherwise not seek help in person. This review aims to investigate the characteristics, acceptability and efficacy of DMHIs specifically developed for socioeconomically and digitally marginalised youth.

METHOD

Key databases were searched widely and systematically (EMBASE, MEDLINE, PsycINFO, OpenGrey). Final inclusion in this review required studies to evaluate DMHIs specifically targeting socioeconomically and digitally marginalised children and young people through a broad range of research designs.

RESULTS

Ten studies, describing seven DHMIs, were included in this review. Studies varied in terms of methodology, population, intervention, outcome measures, technologies used and methodological quality. Qualitative and quantitative results are synthesised across three key phenomena of interest: effectiveness, acceptability and feasibility. Findings suggest that there is moderate but limited evidence supporting DMHIs for improving mental health outcomes among these populations.

CONCLUSIONS

While there is moderate evidence suggesting that digitally delivered interventions can be effective in improving mental health outcomes among socioeconomically and digitally marginalised youth, more high-quality research is needed in order to determine whether DMHIs can fully bridge the so-called 'digital divide'.

Sensory processing and eating behaviours in autism: A systematic review

OBJECTIVES

The aim of this study was to assess the relationship between sensory processing and a broad range of eating behaviours across the lifespan.

METHODS

Five electronic databases of published and unpublished quantitative studies were systematically searched, evaluated for risk of bias and synthesised according to identified eating outcomes.

RESULTS

Across 25 studies, there was consistent evidence of a relationship between sensory processing and a range of eating behaviours. There was early evidence for the particular role of taste/smell sensitivities, as well as hypersensitivities, although future research is needed looking at different sensory patterns and modalities. There was also tentative evidence to suggest this relationship extends across development.

DISCUSSION

Study findings are discussed in relation to implications for sensory-based eating and feeding interventions and the development of eating disorders. Methodological and conceptual limitations are discussed and suggestions for future research are made to address these limitations. A broader investigation of multi-sensory issues and clearly defined eating behaviours, including disordered eating in clinically diagnosed samples, will allow for a more comprehensive and robust understanding of the relationship between sensory processing and eating behaviours in autism.

Changes in peer and sibling victimization in early adolescence: longitudinal associations with multiple indices of mental health in a prospective birth cohort study

Victimization by peers and siblings is associated with poorer mental health outcomes in adolescence. What is less clear is whether mental health outcomes improve if victimization experiences cease (e.g., being victimized in primary school but not secondary school). This study aims to explore how changes in victimization experiences are associated with changes in mental health outcomes in early adolescence. Data are from 13,912 participants in the Millennium Cohort Study (MCS), a nationally representative cohort of individuals born in the UK. Self-reported victimization by peers and siblings, as well as mental health outcomes (depressive symptoms, life satisfaction, self-esteem, and body image), were collected at age 11 and age 14. Victimization at either time point was associated with poorer mental health across the range of outcomes, with effects largest for those who were consistently victimized. Those who reported increasing victimization had greater deterioration in their mental health compared with their peers who were never victimized. Conversely, children whose victimization decreased showed similar mental health development over this period as those who were never victimized. There was a cumulative effect of victimization by peers and siblings, with effect sizes generally larger for experiences with peers. Victimization in adolescence is associated with enduring reductions in mental health. Nonetheless, the promising outcomes associated with reductions in victimization suggest the potential for bullying interventions in schools to limit the deterioration in mental health in victimized groups.

Exploring the association between parental anti-fat attitudes and restrictive feeding practices in a British and Irish sample

Parental restriction of food intake has been associated with heightened eating disorder psychopathology in some longitudinal research. Yet, relatively little is known about the determinants of restrictive feeding practices. This cross-sectional study explored the association between parents' anti-fat attitudes and their use of restrictive feeding practices in a mixed British (41.10% England, 39.90% Scotland, 4.20% Other) and Irish (14.80%) sample. Parents and caregivers (N = 472; 94.10% female; 70.90% university level education) of children between the ages of 4-8 (48.20% female; 91.10% rated as "normal weight" by their parents) completed self-report questionnaires assessing their anti-fat attitudes (dislike, fear, and blame subscales), use of restrictive feeding practices (for weight control, health purposes, and covert restriction), and how influential their child's body-weight and -shape is for their perception of themselves as parents. Overall, our hypothesis that parental anti-fat attitudes would be significantly associated with restrictive feeding practices was supported. Anti-fat attitudes related to disliking higher body-weight people and blaming parents for their child's weight were significant predictors of all forms of restrictive feeding (all ps < .05). However, anti-fat attitudes related to fearing being a higher body-weight were not significant predictors of restrictive feeding for the purposes of health nor for covert restriction (ps > .05). Additionally, our hypothesis that the associations between anti-fat attitudes and restrictive feeding practices would be stronger for parents for whom their child's body-weight and -shape more strongly influenced how they judged themselves as parents was not supported (the interaction term was not significant in two out of three analyses). Future research is needed to investigate these associations across time and in samples of higher body-weight children.

Early weight gain trajectories in first episode anorexia: predictors of outcome for emerging adults in outpatient treatment

BACKGROUND

Early response to treatment has been shown to be a predictor of later clinical outcomes in eating disorders (EDs). Specifically, early weight gain trajectories in anorexia nervosa (AN) have been shown to predict higher rates of later remission in inpatient treatment. However, no study has, as of yet, examined this phenomenon within outpatient treatment of first episode cases of AN or in emerging adults.

METHODS

One hundred seven patients with AN, all between the ages of 16 and 25 and with an illness duration of < 3 years, received treatment via the first episode rapid early intervention in eating disorders (FREED) service pathway. Weight was recorded routinely across early treatment sessions and recovery outcomes (BMI > 18.5 kg/m2 and eating psychopathology) were assessed up to 1 year later. Early weight gain across the first 12 treatment sessions was investigated using latent growth mixture modelling to determine distinct classes of change. Follow-up clinical outcomes and remission rates were compared between classes, and individual and clinical characteristics at baseline (treatment start) were tested as potential predictors.

RESULTS

Four classes of early treatment trajectory were identified. Three of these classes (n = 95), though differing in their early change trajectories, showed substantial improvement in clinical outcomes at final follow-up. One smaller class (n = 12), characterised by a 'higher' start BMI (> 17) and no early weight gain, showed negligible improvement 1 year later. Of the three treatment responding groups, levels of purging, depression, and patient reported carer expressed emotion (in the form of high expectations and low tolerance of the patient) determined class membership, although these findings were not significant after correcting for multiple testing. A higher BMI at treatment start was not sufficient to predict optimal clinical outcomes.

CONCLUSION

First episode cases of AN treated via FREED fit into four distinct early response trajectory classes. These may represent subtypes of first episode AN patients. Three of these four trajectories included patients with substantial improvements 1 year later. For those in the non-response trajectory class, treatment adjustments or augmentations could be considered earlier, i.e., at treatment session 12.

A network meta-analysis of psychological interventions for schizophrenia and psychosis: Impact on symptoms

BACKGROUND

Evidence for the effectiveness of psychological interventions for schizophrenia/psychosis is growing, however there is no consensus on the psychological intervention most likely to reduce symptoms.

METHODS

A network meta-analysis was conducted to identify all randomised controlled trials (RCTs) of psychological interventions for adults with schizophrenia/psychosis. A systematic review of the literature using MEDLINE, PsycINFO, EMBASE and CENTRAL led to an analysis of 90 RCTs with 8440 randomised participants across 24 psychological intervention, and control groups. Psychological interventions were categorised and rated for treatment fidelity and risk of bias. Data for total symptoms were extracted and network meta-analysis, using a frequentist approach, was undertaken using Stata SE v15 to compare the direct and indirect evidence for the effectiveness of each psychological intervention.

FINDINGS

Psychological interventions were more likely to reduce symptoms than control groups, and one intervention, mindfulness-based psychoeducation, was consistently ranked as most likely to reduce total symptoms. Subgroup analyses identified differential effectiveness in different settings and for different subgroups.

INTERPRETATION

Mindfulness-based psychoeducation was consistently ranked as most likely to reduce symptoms; however all studies were based in China. More RCTs in a variety of cultural contexts would help to elucidate whether these findings generalise internationally. A number of psychological interventions could potentially be more effective than interventions recommended by NICE guidelines, such as CBT and family therapy, and additional RCTs and meta-analyses are needed to generate more conclusive evidence in this regard.

Mixed methods pilot evaluation of interpersonal psychotherapy for body image for adolescents

Body dissatisfaction is common in adolescence and associated with poor outcomes. The aim of this mixed method pilot evaluation was to determine acceptability, feasibility and preliminary efficacy of Interpersonal Psychotherapy for Body Image (IPT-BI), a school-based group intervention for young people with high levels of body dissatisfaction. Eighteen participants (11-13 years, 78% female) took part in two IPT-BI groups (n = 10; n = 8). Feasibility was measured by recruitment and attrition rates; acceptability using a treatment satisfaction questionnaire and focus groups; and clinical outcomes at baseline, each session and post intervention. The majority of young people (72%, n = 18/25) who were referred or expressed interest went on to take part. Average session attendance was 100% and 89%. Participants expressed high levels of treatment satisfaction with 94% (n = 16/17) rating IPT-BI as 'quite helpful' or 'very helpful' and 94% (n = 16/17) stating they would recommend it to others. Preliminary exploration of efficacy showed significant improvements in body image and significant reductions in interpersonal difficulties and appearance-based conversations. Young people valued specific IPT-BI skills (role play, communication strategies), alongside generic therapeutic factors (therapeutic alliance, group cohesion). IPT-BI is feasible and acceptable with promising provisional clinical outcomes indicating the need for a fully powered randomised controlled trial.

A qualitative exploration of the impact of COVID-19 on individuals with eating disorders in the UK

COVID-19 may have substantial impact on the mental health at a population level, but also has the potential to significantly affect those with pre-existing mental health difficulties such as eating disorders. This qualitative study explores the impact of COVID-19 and associated public health measures on adults with eating disorders within the UK. We conducted 10 in depth interviews with adults (24-38 years) with a self-reported eating disorder during lockdown. Data were analysed using an inductive thematic analysis approach. We identified core themes related to social restrictions (social isolation, changes in accountability to others, and increased responsibility for self and others), functional restrictions (lack of routine and structure, a need to intentionally plan activity, a desire for secrecy particularly around food shopping) and restrictions in access to mental health services. Overall, the impact of the lockdown was experienced as a catalyst for either increased disordered eating behaviours or for a drive for recovery, depending on individual circumstances going into these restrictions. This study is the first in depth interview approach with adults with mixed eating disorder presentations in the UK during COVID-19. Findings have important implications for post lockdown intervention care and practice.

Exploring changes in body image, eating and exercise during the COVID-19 lockdown: A UK survey

Early reports suggest that lockdown measures associated with the COVID-19 pandemic (e.g., social distancing) are having adverse consequences for people's mental health, including increases in maladaptive eating habits and body dissatisfaction. Certain groups, such as those with pre-existing mental health difficulties, may be especially at risk. The current study explored perceived changes in eating, exercise, and body image during lockdown within the United Kingdom, using an online survey (n = 264). There were large individual differences in perceived changes in eating, exercise, and body image in this period. Women were more likely than men to report increasing struggles with regulating eating, preoccupation with food and worsening body image. Those with a current/past diagnosis of eating disorders reported significantly greater difficulties in regulating eating, increased preoccupation with food, exercise thoughts and behaviours and concern about appearance, even when compared to those with other mental health and developmental disorders. Ongoing research to explore individual differences in the trajectories of change in eating, exercise and body image as lockdown measures ease will be important for understanding the full psychological impact of this pandemic and improve service and public health planning going forward.

Close proximity to alcohol outlets is associated with increased crime and hazardous drinking: Pooled nationally representative data from New Zealand

This nationwide study investigated the relationship between proximity to alcohol outlets (off-licence, on-licence, and other-licence) and two adverse outcomes; hazardous drinking and crime (common assault, non-aggravated sexual assault, aggravated sexual assault, and tobacco and liquor offences). After adjustment for important individual- and area-level factors, close proximity to alcohol outlets was associated with increased risk of hazardous drinking, with strong associations for on-licence outlets. Proximity alcohol outlets was also strongly associated with all crime outcomes, often with a dose-response relationship. Nationally representative New Zealand data showed that close proximity to alcohol outlets was associated with increased crime and hazardous drinking.

The psychometric properties of Orthorexia Nervosa assessment scales: A systematic review and reliability generalization

The main objective of this systematic review was to provide a comprehensive overview of the psychometric properties of all available Orthorexia Nervosa (ON) assessment tools, in order to evaluate their scope of application for research and practice. Ten databases were searched for studies quantitatively assessing ON. The psychometric properties were evaluated according to specified quality criteria, focusing on the reliability, structural validity and construct validity of the scales. A meta-analytic approach was used to summarize eligible Cronbach's alpha coefficients between studies. Sixty-eight unique studies fulfilled the inclusion criteria for this systematic review. Ten discrete ON scales were identified. Half of the included studies exclusively utilized a version of the ORTO-15. The evaluation of all available ON measures raise issues regarding ON's dimensionality and conceptualization. Most of the identified scales require further validation. Based on the reported psychometric properties it is advised to re-evaluate existing tools and to focus on establishing consensus regarding the conceptualization of ON to establish a measure with sound psychometric properties.

Adult Asthma Diagnosis: Physician Reported Challenges in Alberta-Based Primary Care Practices

Introduction

An estimated 8.1% of Canadians adults have asthma. While there are challenges associated with the use of objective measurement of lung function in the diagnosis of asthma, we are uncertain of the barriers that impact the use of objective measures, and have limited understanding of the challenges experienced by primary care providers in diagnosis of asthma. The objectives of this quality improvement initiative were to identify primary care providers’ methods of diagnosing asthma and to identify challenges with diagnosis.

Methods

An online survey was disseminated using a snowball methodology.

Setting

Primary care practices in Alberta, Canada.

Participants

A total of 84 primary care providers completed the survey.

Main Outcome Measures

Participants were asked their ideal and sufficient methods for diagnosing asthma and to identify challenges in their practice related to asthma diagnosis.

Results

They identified full pulmonary function testing (54%), pre- and postbronchodilator spirometry (54%), complete history and physical (42%), peak flow measurement overtime (26%), pulmonary consult (26%), and trial of asthma medication(s) (23%), as ideal methods of diagnosing asthma. The most significant barriers to diagnosis included episodic care–care provided typically during times of worsening symptoms without ongoing preventative/maintenance care (55%), patient follow-up (44%), conflict between clinical impression and pulmonary function results (43%), patient already on asthma medications (43%), and interpreting spirometry/pulmonary function results (39%).

Conclusion

The results of this survey indicate that the majority of primary care providers would choose full pulmonary function testing or pre- and postbronchodilator spirometry as the ideal methods of diagnosing asthma. However, barriers related to the nature of asthma care, patient factors, and challenges with diagnostic testing create challenges. This study also highlights that primary care providers have adapted to challenges in leveraging objective measurement and may rely upon other methods for diagnosis such as trials of medications.

SafeSpot: an innovative app and mental health support package for Scottish schools - a qualitative analysis as part of a mixed methods study

AIMS

The aim of the study was to investigate teachers' and pupils' perceptions about the effect of the SafeSpot mental health curriculum on the well-being of young people and on their knowledge of mental health conditions. This trial intends to determine the acceptability and benefits of web and mobile technology in delivering emotional well-being in schools, through use of the SafeSpot programme.

BACKGROUND

With 10% of young people aged 5 to 16 diagnosed with a mental disorder, there is pressure for schools to address their pupils' emotional well-being. However, many educators report that their schools have insufficient provisions and feel inadequately equipped to support pupils' mental health.

METHODS

This qualitative analysis was embedded within a randomly allocated stepped-wedge design, conducted in six West of Scotland secondary schools. A total of 2320 pupils (aged 11 to 14 years) and 90 teachers were included. Young people's understanding of health-seeking, and teacher's confidence in delivering and accessing well-being information was assessed qualitatively.

RESULTS

Qualitative analysis revealed themes highlighting the beneficial nature of SafeSpot, including pupil engagement, content of tutorials, perceived impact of SafeSpot and level of training provided for teachers.

CONCLUSIONS

Web technology could potentially offer a more structured way for staff to support their pupils' mental health, whilst reducing stigma. SafeSpot was perceived, by pupils and teachers, to be engaging.

Review: The effectiveness of interpersonal psychotherapy for adolescents with depression - a systematic review and meta-analysis

BACKGROUND

Interpersonal psychotherapy for adolescents (IPT-A) is a manualised, time-limited intervention for young people with depression. This systematic review aimed to determine the effectiveness of IPT-A for treating adolescent depression.

METHOD

A systematic search of relevant electronic databases and study reference lists was conducted. Any study investigating the effectiveness of IPT-A in 12- to 20-year-olds with a depressive disorder was eligible. Synthesis was via narrative summary and meta-analysis.

RESULTS

Twenty studies were identified (10 randomised trials and 10 open trials/case studies), many of which had small sample sizes and were of varying quality. Following IPT-A, participants experienced large improvements in depression symptoms (d = -1.48, p < .0001, k = 17), interpersonal difficulties with a medium effect (d = -0.68, p < .001, k = 8) and in general functioning with a very large effect (d = 2.85, p < .001, k = 8). When compared against control interventions, IPT-A was more effective than non-CBT active controls in reducing depression symptoms (d = -0.64, p < .001, k = 5) and was no different from CBT (d = 0.05, p = .88, k = 2). There was no difference between IPT-A and active control interventions in reducing interpersonal difficulties (d = -0.26, p = .25, k = 5).

CONCLUSIONS

Interpersonal psychotherapy for adolescents is an effective intervention for adolescent depression, improving a range of relevant outcomes. IPT-A is consistently superior to less structured interventions and performs similarly to CBT. However, these conclusions are cautious, as they are based on a small number of controlled studies, with minor adaptations to the standard IPT-A protocol, and/or were conducted by the intervention developers. Further robust RCTs are therefore required. The lack of superiority in IPT-A for improving interpersonal difficulties highlights a need for studies to explore the underpinning mechanisms of change.

The relative importance of dissatisfaction, overvaluation and preoccupation with weight and shape for predicting onset of disordered eating behaviors and depressive symptoms over 15 years

OBJECTIVE

The aim of this study was to examine the relative importance of dissatisfaction, overvaluation, and preoccupation with body weight and shape in predicting increases in disordered eating behaviors and depressive symptoms from adolescence through to early adulthood.

METHOD

The study involved 1,830 participants (60% female) who completed the Project EAT survey during adolescence (mean age = 14.90 years, SD = 1.65 years) and again, 15 years later, in early adulthood. Participants provided assessments of dissatisfaction, overvaluation and preoccupation with weight and shape, as well as disordered eating and depressive symptoms at both time points.

RESULTS

The three aspects of body image had distinct patterns of association with the outcomes both concurrently and longitudinally. Dissatisfaction predicted depressive symptoms as well as a wide range of disordered eating outcomes, including dieting, unhealthy weight control behaviors (UWCBs), and binge eating, particularly in female participants. Preoccupation was associated with all of these disordered eating behaviors (but not with depressive symptoms) and was notably the strongest predictor of dieting and UWCBs in female participants. Overvaluation was associated with both disordered eating and depressive symptoms, although typically was a less potent predictor of difficulties than the other aspects of body image.

DISCUSSION

Dissatisfaction, overvaluation, and preoccupation are related but make distinct contributions to clinically significant outcomes. Models of eating disorders should move beyond focusing exclusively on dissatisfaction or overvaluation toward a broader conceptualisation of body image. Findings from this study particularly suggest the importance of considering preoccupation with weight and shape.

Web-based indicated prevention of common mental disorders in university students in four European countries - Study protocol for a randomised controlled trial

BACKGROUND

Mental disorders and their symptoms are highly prevalent in the university student population, and the transition from secondary to tertiary education is associated with a rise in mental health problems. Existing web-based interventions for the prevention of common mental disorders in student populations often focus on just one disorder and have not been designed specifically for students. There is thus a need for transdiagnostic, student-specific preventative interventions that can be widely disseminated. This two-arm, parallel group randomised controlled trial aims to evaluate the effectiveness and cost-effectiveness of a web-based transdiagnostic mental health problem prevention programme (PLUS) across several universities in four countries.

METHOD

Students (N = 5550) will be recruited through a variety of channels and asked to complete a personality assessment to determine whether they are at high risk for developing common mental disorders. Students at high risk will be randomly allocated to either PLUS or a control intervention, which provides practical support around issues commonly experienced at university. Students at low risk will be allocated to the control intervention. Both intervention groups will be assessed at baseline, 4 weeks, 3 months, 6 months and 12 months after randomisation. Depression and generalised anxiety, assessed using the Patient Health Questionnaire and the Generalised Anxiety Disorder scales, will form the primary outcomes in this study. Secondary outcome measures include alcohol and drug use, eating behaviour, self-esteem, and quality of life. The cost-effectiveness of the intervention will also be evaluated.

CONCLUSIONS

This study will contribute to understanding the role of transdiagnostic indicated web-based interventions for the prevention of common mental disorders in university students. It will also be one of the first studies to investigate the cost-effectiveness of such interventions.

Treatment of anorexia nervosa: a multimethod investigation translating experimental neuroscience into clinical practice

Background

Anorexia nervosa (AN) is a severe psychiatric condition and evidence on how to best treat it is limited.

Objectives

This programme consists of seven integrated work packages (WPs) and aims to develop and test disseminable and cost-effective treatments to optimise management for people with AN across all stages of illness.

Methods

WP1a used surveys, focus groups and a pre–post trial to develop and evaluate a training programme for school staff on eating disorders (EDs). WP1b used a randomised controlled trial (RCT) [International Standard Randomised Controlled Trial Number (ISRCTN) 42594993] to evaluate a prevention programme for EDs in schools. WP2a evaluated an inpatient treatment for AN using case reports, interviews and a quasi-experimental trial. WP2b used a RCT (ISRCTN67720902) to evaluate two outpatient psychological therapies for AN. WP3 used a RCT (ISRCTN06149665) to evaluate an intervention for carers of inpatients with AN. WP4 used actimetry, self-report and endocrine assessment to examine physical activity (PA) in AN. WP5 conducted a RCT (ISRCTN18274621) of an e-mail-guided relapse prevention programme for inpatients with AN. WP6 analysed cohort data to examine the effects of maternal EDs on fertility and their children’s diet and growth. WP7a examined clinical case notes to explore how access to specialist ED services affects care pathways and user experiences. Finally, WP7b used data from this programme and the British Cohort Study (1970) to identify the costs of services used by people with AN and to estimate annual costs of AN for England.

Results

WP1a: a brief training programme improved knowledge, attitudes and confidence of school staff in managing EDs in school. WP1b: a teacher-delivered intervention was feasible and improved risk factors for EDs in adolescent girls. WP2a: both psychological therapies improved outcomes in outpatients with AN similarly, but patients preferred one of the treatments. WP2b: the inpatient treatment (Cognitive Remediation and Emotional Skills Training) was acceptable with perceived benefits by patients, but showed no benefits compared with treatment as usual (TAU). WP3: compared with TAU, the carer intervention improved a range of patient and carer outcomes, including carer burden and patient ED symptomatology. WP4: drive to exercise is tied to ED pathology and a desire to improve mood in AN patients. PA was not increased in these patients. WP5: compared with TAU, the e-mail-guided relapse prevention programme resulted in higher body mass index and lower distress in patients at 12 months after discharge. WP6: women with an ED had impaired fertility and their children had altered dietary and growth patterns compared with the children of women without an ED. WP7a: direct access to specialist ED services was associated with higher referral rates, lower admission rates, greater consistency of care and user satisfaction. WP7b: the annual costs of AN in England are estimated at between £45M and £230M for 2011.

Conclusions

This programme has produced evidence to inform future intervention development and has developed interventions that can be disseminated to improve outcomes for individuals with AN. Directions for future research include RCTs with longer-term outcomes and sufficient power to examine mediators and moderators of change.

Use, acceptability and impact of booklets designed to support mental health self-management and help seeking in schools: results of a large randomised controlled trial in England

Mental health booklets may provide a low-cost means of promoting mental health self-management and help seeking in schools. The aim of the study was to assess the (a) use, (b) acceptability and (c) impact of booklets for students in primary (10-11 years) and secondary school (12-13 years) alone and in conjunction with funding for targeted mental health support. This was a 2 × 2 factorial cluster randomized controlled trial, in which 846 schools in England were randomly allocated to receive/not receive: (1) booklets for students containing information on mental health self-management and help seeking, and (2) funding for mental health support as part of a national mental health initiative. 14,690 students (8139 primary, 6551 secondary) provided self-report on mental health, quality of life (baseline and 1 year follow-up) and help seeking (follow-up). (a) Approximately, 40 % primary school students and 20 % secondary school students reported seeing the booklets. (b) Of these, 87 % of primary school students reported that the booklet was 'very helpful' or 'quite helpful', compared with 73 % in secondary school. (c) There was no detectable impact of booklets on mental health, quality of life or help seeking, either alone or in conjunction with additional funding through the national mental health initiative. Lack of discernable impact of booklets underscores the need for caution in adopting such an approach. However, it is feasible that the impact was obscured by low uptake or that booklets may be more effective when used in a targeted way.

Survey of schools' work with child and adolescent mental health across England: a system in need of support

BACKGROUND

With evidence of rising need around mental health in young people, cuts in specialist health provision and increasing recognition of the central role of schools in supporting young people with mental health problems, it is important to understand the provision of mental health support currently available in schools, the nature of the relationship with health and other providers of child and adolescent mental health (CAMH) services, and what are the key barriers to accessing support.

METHOD

The study was a convenience sample survey of 577 school staff from 341 schools in England. Participants completed an online survey about the provision of specialist mental health support in their school, including what support is available, who provides it, and perceived barriers to supporting the mental health of young people. Data were linked to publicly available data on school characteristics.

RESULTS

Over two thirds of schools reported having some specialist support available, with specialist provision more common in secondary schools. Staff training and whole-school approaches were the most frequently employed specific approaches. Support was most often provided by educational psychologists, followed by counsellors. School staff particularly valued support and feedback within the schools context. The most frequently cited barrier to mental health support was the limited capacity of specialist CAMH services.

CONCLUSIONS

The results suggest a need to enhance the availability of specialist support for mental health both within schools and in CAMH services.

Internalising symptoms and body dissatisfaction: untangling temporal precedence using cross-lagged models in two cohorts

BACKGROUND

Cross-sectional studies demonstrate that body dissatisfaction and internalising symptoms are correlated and are both overrepresented in girls compared to boys. However, it is not clear whether body dissatisfaction typically precedes internalising symptoms or vice versa. Existing literature provides theoretical and empirical support for both possibilities, but is limited in two ways: (a) no study has simultaneously tested the two temporal hypotheses within the same model, and (b) the studies focus almost exclusively on early adolescents resulting in little being known about development from preadolescence and across puberty.

METHODS

This study used data from 5485 primary school students (49.1% girls, aged 8-9 years at baseline) and 5981 secondary school students (53.9% girls, aged 11-12 years at baseline). Self-reports of internalising symptoms and body dissatisfaction were collected over three consecutive years at 1-year intervals. Cross-lagged models were estimated in the two cohorts, for boys and girls separately, to examine the temporal associations between these two domains across the three measurement points.

RESULTS

In the younger cohort, internalising symptoms predicted body dissatisfaction 1-year later for both boys and girls, whereas there was no evidence for the reverse being true. In the older cohort, internalising symptoms predicted later body dissatisfaction for boys. However, in girls, body dissatisfaction predicted later internalising symptoms.

CONCLUSIONS

In preadolescents, internalising symptoms drive later body dissatisfaction regardless of gender, suggesting body dissatisfaction is a specific manifestation of a tendency towards negative affect. From age 11, girls develop a distinct risk profile whereby body dissatisfaction drives later internalising symptoms. Preventative interventions in this field would benefit from adopting a developmentally sensitive approach that takes into account gender differences in risk pathways.

Mental Health Difficulties in Early Adolescence: A Comparison of Two Cross-Sectional Studies in England From 2009 to 2014

PURPOSE

To examine the changes in mental health difficulties in early adolescence between 2009 and 2014 in England.

METHODS

Analysis reports on data from two cross-sectional samples of adolescents (aged 11-13 years) collected 5 years apart in 2009 and 2014 in secondary schools across England. Samples were matched using propensity scoring, resulting in a total pooled sample of 3,366 adolescents. Mental health difficulties were reported by participants using the Strengths and Difficulties Questionnaire.

RESULTS

Overall, there were similar levels of mental health difficulties experienced by adolescents in 2009 and 2014. Notable exceptions were a significant increase in emotional problems in girls and a decrease in total difficulties in boys in 2014 compared to 2009.

CONCLUSIONS

The increased prevalence of emotional problems in girls mirrors a trend found in other similar studies, and the results are discussed in the context of recent economic and societal changes. The small decrease in total difficulties in boys, although promising, clearly warrants further research.

The role of high-quality friendships in female adolescents' eating pathology and body dissatisfaction

PURPOSE

Peers may serve as risk factors for body dissatisfaction and eating pathology through two possible routes: (1) promoting body dissatisfaction through appearance-related interactions (e.g. weight-teasing); (2) a non-specific social support route whereby poor quality peer relations result in depression and consequently eating pathology. The second route has received little attention and, therefore, was the focus of this study.

METHODS

A cross-sectional study in which 216 adolescent girls (aged 13-16 years) completed self-report measures of positive and negative friendship qualities, friendship functions, eating pathology, body dissatisfaction and depression.

RESULTS

Those reporting poorer quality friendships tended to show greater eating pathology and greater body dissatisfaction. These associations were reduced to non-significance when covarying depression. There was no evidence that the role of friendships was moderated by the extent to which participants valued close relations.

CONCLUSIONS

Low-quality friendships are associated with disordered eating and may be suitable targets for prevention.

'My teacher saved my life' versus 'Teachers don't have a clue': an online survey of pupils' experiences of eating disorders

BACKGROUND

Eating disorders (ED) have a peak rate of onset in school-aged children. Little is known about pupils' experiences of ED within a school setting.

METHOD

Five hundred and eleven 11- to 19-year-old school pupils completed an online questionnaire exploring their experiences of ED (72% female, 28% male). Responses were analysed using content analysis principles.

RESULTS

Of the participants, 38% had a current or past ED, 49% of these had never received a formal diagnosis. Of the respondents, 59% saw a need to raise ED awareness. Only 7% would confide in a teacher about an ED.

CONCLUSIONS

Efforts are needed to break down barriers to disclosure and support teachers to play an effective role in the detection and early intervention for ED.

Threat-related attentional bias in anorexia nervosa

OBJECTIVE

Attentional bias (AB) modification treatment targeting general or social anxiety has been recently highlighted as a potential novel approach for the treatment of anorexia nervosa (AN). The purpose of this study was to examine threat-related AB in patients with ANand healthy control participants (HC) and the relationship between AB and eating disorder and other psychopathology.

METHOD

Forty-nine female outpatients with AN or Eating Disorder Not Otherwise Specified, Anorexia Type (EDNOS-AN), and 44 female HC completed a dot-probe task with threat words and a range of self-report measures assessing eating disorder symptoms and other psychopathology.

RESULTS

There was no evidence for a differential threat-related AB in AN patients despite elevated anxiety in this group. The AB-index, a parameter of the magnitude of attention allocation when two competing stimuli are presented, did not correlate with any of the self-report measures. However, patients with AN responded significantly more slowly to the probe as compared to controls, regardless of the valence or position of the stimuli.

DISCUSSION

The results suggest that the AB in AN patients may be specific to eating disorder-relevant anxieties.

Feasibility, acceptability and efficacy of a school-based prevention programme for eating disorders: cluster randomised controlled trial

BACKGROUND

Body image dissatisfaction during adolescence is common but not benign. School-based interventions have the potential for wide reach, but scalability of previous programmes is limited by a reliance on external facilitators.

AIMS

To assess the acceptability, feasibility and efficacy of a teacher-delivered body image intervention.

METHOD

A pilot clustered randomised controlled trial in which 16 classes of adolescent girls were allocated to a 6-session body image programme (n = 261), or usual curriculum control (n = 187) (registration: ISRCTN42594993).

RESULTS

Students in the intervention group had significantly improved body esteem and self-esteem and reduced thin-ideal internalisation. Effects for body esteem and thin-ideal internalisation were maintained for 3 months. There were no group differences for eating pathology, peer factors or depression. Acceptability, feasibility and efficacy varied between schools.

CONCLUSIONS

Teacher-delivered body image lessons have promise but further work is needed to increase efficacy and make interventions suitable across a range of schools.

Is fat talking a causal risk factor for body dissatisfaction? A systematic review and meta-analysis

OBJECTIVE

Fat talking has been assumed to be a causal risk factor for body dissatisfaction in a number of prevention programs and body confidence campaigns. The aim of this paper was to assess whether fat talking meets three criteria necessary for causal risk factors, namely whether fat talking is: (a) cross-sectionally associated with body dissatisfaction; (b) prospectively associated with changes in body dissatisfaction; and (c) associated with changes in body dissatisfaction in experimental studies.

METHOD

A systematic literature review was conducted using electronic databases and hand searching of relevant journals. Meta-analyses provided pooled effect size estimates, and meta-regressions were used to determine whether age, gender or risk of bias were effect modifiers of the relationship.

RESULTS

Searches revealed 24 studies. There was a significant cross-sectional association (r = 0.297, 95% CI = 0.225-0.349), which differed in strength between age groups and genders. There was a prospective association between fat talking and changes in body dissatisfaction in long term (r = 0.144, 95% CI = 0.050-0.234), but not in short-term studies (r = 0.022, 95% CI = -0.131-0.174). One study showed that experimental exposure to fat talking was associated with increases in body dissatisfaction (d = 0.124).

DISCUSSION

As such, there is good evidence that fat talking is a correlate of body dissatisfaction. The few prospective and experimental studies give an initial indication that fat talking is a causal risk factor for body dissatisfaction. Further work is needed to support this position.

The reporting of fidelity measures in primary prevention programmes for eating disorders in schools

OBJECTIVE

The aim of this paper was to examine the extent to which controlled trials of face-to-face school-based primary prevention for eating disorders report their strategies for maintaining fidelity.

METHOD

A systematic review located 38 articles eligible for inclusion. These studies were assessed using 18 criteria for reporting fidelity maintenance strategies based on those recommended by the Treatment Fidelity Workgroup of the National Institute of Health Behavior Change Consortium.

RESULTS

Fidelity reporting was generally poor. The studies reported between 22% and 56% of fidelity criteria. Detailed reporting of curriculum-as-usual control conditions was generally lacking, as were methods to ensure high-quality training and mechanisms to assess provider adherence to intervention protocol.

DISCUSSION

Poor fidelity assessment and reporting is a problem in school-based primary prevention programmes for eating disorders. Recommendations for improving fidelity maintenance and reporting practices are provided.

Uncommon presentation of a common condition: an easily missed cause of hip pain

Conventionally, patients presenting with hip pain and restricted mobility to accident and emergency (A&E) department are thought to have musculoskeletal pain. Occasionally, patients with significant abdominal pathology can present with hip pain. Such atypical presentation causes the delayed diagnosis leading to significant morbidity and possible mortality. We report a 63-year-old man who had been treated in A&E on numerous occasions with left hip pain for over 6 weeks. On this occasion, he had been brought in septic shock. On examination, he had subcutaneous emphysema of left lower limb. A CT scan showed a large psoas abscess resulting from retroperitoneal perforation of sigmoid diverticulitis tracking into his left lower limb. He underwent a Hartmann's procedure and drainage of his intra-abdominal sepsis. The thigh was not drained with separate incisions at the index operation. Residual thigh abscess was managed by image-guided drainage.

Analysis of C. elegans intestinal gene expression and polyadenylation by fluorescence-activated nuclei sorting and 3'-end-seq

Despite the many advantages of Caenorhabditis elegans, biochemical approaches to study tissue-specific gene expression in post-embryonic stages are challenging. Here, we report a novel experimental approach for efficient determination of tissue-specific transcriptomes involving the rapid release and purification of nuclei from major tissues of post-embryonic animals by fluorescence-activated nuclei sorting (FANS), followed by deep sequencing of linearly amplified 3'-end regions of transcripts (3'-end-seq). We employed these approaches to compile the transcriptome of the developed C. elegans intestine and used this to analyse tissue-specific cleavage and polyadenylation. In agreement with intestinal-specific gene expression, highly expressed genes have enriched GATA-elements in their promoter regions and their functional properties are associated with processes that are characteristic for the intestine. We systematically mapped pre-mRNA cleavage and polyadenylation sites, or polyA sites, including more than 3000 sites that have previously not been identified. The detailed analysis of the 3'-ends of the nuclear mRNA revealed widespread alternative polyA site use (APA) in intestinally expressed genes. Importantly, we found that intestinal polyA sites that undergo APA tend to have U-rich and/or A-rich upstream auxiliary elements that may contribute to the regulation of 3'-end formation in the intestine.

Factors associated with poor asthma control in children aged five to 13 years

BACKGROUND

Most children with asthma should be able to achieve acceptable control. However, are there differences between those with acceptable and poor control, and if so, how can health care approaches be modified accordingly?

OBJECTIVE

To examine the characteristics of elementary school children aged five to 13 years with acceptable and poor levels of asthma control.

METHODS

The present cross-sectional study of children with asthma used five indicators of control, as outlined by the Canadian Asthma Consensus Report, to categorize acceptable and poor asthma control.

RESULTS

Of 153 children, 115 (75%) were rated as having poorly controlled asthma. Of those with poor control, 65 (64%) children were currently using inhaled corticosteroids, and 65% of those reported using inhaled corticosteroids daily versus as needed. Fifty-one per cent of the children with poorly controlled asthma had exposure to tobacco smoke, whereas 79% of the children with asthma under acceptable control were from households with no smokers (P=0.002). The poor control group also had significantly worse parental perceptions of the psychosocial impact of asthma on their child. No significant difference was found in the percentage of those who had written action plans in the poor control group (28%) compared with the acceptable control group (26%), and similar percentages in each group stated that they used the plans.

CONCLUSIONS

Despite the high use of inhaled corticosteroids, the majority of children had poorly controlled asthma. The poor control group had more exposure to tobacco smoke and a worse psychosocial impact due to asthma. Few children had past asthma education and action plans, suggesting that there is a need to improve access to and tools for education.

The influence of response–time demands on electrophysiological correlates of successful episodic retrieval

Event-related potentials (ERPs) were acquired in two memory retrieval tasks. In Experiment 1 a 2.5 s response-time limit was imposed at test, while in Experiment 2 there was no explicit upper limit. There were no other structural differences between the two experiments. The response-time manipulation did not influence the accuracy of memory judgements, but resulted in qualitative changes in the ERP old/new effects that were elicited in the two tasks. In Experiment 2, the ERP old/new effects from 700 ms post-stimulus onwards comprised a relatively greater positivity for correct judgements to old items in comparison to correct judgements to new items. In keeping with findings in previous studies, this relative positivity was largest at anterior sites over the right hemisphere. In Experiment 1, by contrast, the ERP old/new effects during the same time window were most prominent at right hemisphere central electrode locations, and comprised a relatively greater positivity for correct judgements to new rather than to old test items. In combination, the findings in the two experiments are consistent with the view that the imposition of different response-time demands results in the engagement of neurally and functionally distinct processes during episodic retrieval. The time course of these distinct ERP old/new effects suggests that different post-retrieval monitoring operations were engaged according to the time available to make memory judgements.
