    Integral to the diagnosis of autism spectrum disorder (ASD) is the initial assessment through which the existence of a ‘problem’ is first ascertained. Despite this, there remains limited research on this early part of the diagnostic pathway. In this paper, we utilised conversation analysis to examine relevant issues in relation to the practitioner-family interactions that take place within this initial assessment context. Our findings illustrated that parents typically first raised the possibility of the presence of an ASD diagnosis through ‘building a case’, which professionals were then able to ratify or negate. Further, we found that the assessments unfolded sequentially and clinical decisions were typically reached through a distinctive pattern of interaction. These findings have important implications for clinical practice, including for the study of ASD assessments and diagnosis

    The objective was to identify how children's knowledge positions were negotiated in child mental health assessments and how this was managed by the different parties.The child psychiatry data consisted of 28 video-recorded assessments. A conversation analysis was undertaken to examine the interactional detail between the children, parents, and practitioners.The findings indicated that claims to knowledge were managed in three ways. First, practitioners positioned children as 'experts' on their own health and this was sometimes accepted. Second, some children resisted this epistemic position, claiming not to have the relevant knowledge. Third, some children's claims to knowledge were negotiated and sometimes contested by adult parties who questioned their competence to share relevant information about their lives in accordance with the assessment agenda.Through question design, the practitioner was able to position the child as holding relevant knowledge regarding their situation. The child was able to take up this position or resist it in various ways.This has important implications for debates regarding children's competence to contribute to mental health interventions. Children are often treated as agents with limited knowledge, yet in the mental health assessment they are directly questioned about their own lives

    Reflective interventionist conversation analysis

    © The Author(s) 2020. A distinction has been drawn between basic (pure) conversation analysis (CA) and applied CA. Applied CA has become especially beneficial for informing areas of practice such as health, social care and education, and is an accepted form of research evidence in the scientific rhetoric. There are different ways of undertaking applied CA, with different foci and goals. In this article, we articulate one way of conducting applied CA, that is especially pertinent for practitioners working in different fields. We conceptualise this as Reflective Interventionist CA (RICA). We argue that this approach to applied CA is important because of its emphasis on the reflective stance that is valuable to an understanding of research data, its commitment to collaboration with practitioners, and its inductive style. In this paper, we outline the core premises and benefits of this approach and offer empirical examples to support our argument. To conclude, we consider the implications for evidence-based practice

    Building a case for accessing service provision in child and adolescent mental health assessments

    In everyday conversations, people put forward versions of events and provide supporting evidence to build a credible case. In environments where there are potentially competing versions, case-building may take a more systematic format. Specifically, we conducted a rhetorical analysis to consider how in child mental health settings, families work to present a credible ‘doctorable’ reason for attendance. Data consisted of video-recordings of 28 families undergoing mental health assessments. Our findings point to eight rhetorical devices utilised in this environment to build a case. The devices functioned rhetorically to add credibility and authenticate the case being built, which was relevant as the only resource available to families claiming the presence of a mental health difficulty in the child were their spoken words. In other words, the ‘problem’ was something constructed through talk and therefore the kinds of resources used were seminal in decision-making

    Differential activation of the frontal pole to high vs low calorie foods: The neural basis of food preference in Anorexia Nervosa?

    Get PDF
    Neuroimaging studies in anorexia nervosa (AN) suggest that altered food reward processing may result from dysfunction in both limbic reward and cortical control centers of the brain. This fMRI study aimed to index the neural correlates of food reward in a subsample of individuals with restrictive AN: twelve currently ill, fourteen recovered individuals and sixteen healthy controls. Participants were shown pictures of high and low-calorie foods and asked to evaluate how much they wanted to eat each one following a four hour fast. Whole-brain task-activated analysis was followed by psychophysiological interaction analysis (PPI) of the amygdala and caudate. In the AN group, we observed a differential pattern of activation in the lateral frontal pole: increasing following presentation of high-calorie stimuli and decreasing in during presentation of low-calorie food pictures, the opposite of which was seen in the healthy control (HC) group. In addition, decreased activation to food pictures was observed in somatosensory regions in the AN group. PPI analyses suggested hypo-connectivity in reward pathways, and between the caudate and both somatosensory and visual processing regions in the AN group. No significant between-group differences were observed between the recovered group and the currently ill and healthy controls in the PPI analysis. Taken together, these findings further our understanding of the neural processes which may underpin the avoidance of high-calorie foods in those with AN and might exacerbate the development of compulsive weight-loss behavior, despite emaciation

    The development and validation of a scoring tool to predict the operative duration of elective laparoscopic cholecystectomy

    Background: The ability to accurately predict operative duration has the potential to optimise theatre efficiency and utilisation, thus reducing costs and increasing staff and patient satisfaction. With laparoscopic cholecystectomy being one of the most commonly performed procedures worldwide, a tool to predict operative duration could be extremely beneficial to healthcare organisations. Methods: Data collected from the CholeS study on patients undergoing cholecystectomy in UK and Irish hospitals between 04/2014 and 05/2014 were used to study operative duration. A multivariable binary logistic regression model was produced in order to identify significant independent predictors of long (> 90 min) operations. The resulting model was converted to a risk score, which was subsequently validated on second cohort of patients using ROC curves. Results: After exclusions, data were available for 7227 patients in the derivation (CholeS) cohort. The median operative duration was 60 min (interquartile range 45–85), with 17.7% of operations lasting longer than 90 min. Ten factors were found to be significant independent predictors of operative durations > 90 min, including ASA, age, previous surgical admissions, BMI, gallbladder wall thickness and CBD diameter. A risk score was then produced from these factors, and applied to a cohort of 2405 patients from a tertiary centre for external validation. This returned an area under the ROC curve of 0.708 (SE = 0.013, p  90 min increasing more than eightfold from 5.1 to 41.8% in the extremes of the score. Conclusion: The scoring tool produced in this study was found to be significantly predictive of long operative durations on validation in an external cohort. As such, the tool may have the potential to enable organisations to better organise theatre lists and deliver greater efficiencies in care

    Dissecting the Shared Genetic Architecture of Suicide Attempt, Psychiatric Disorders, and Known Risk Factors

    Background Suicide is a leading cause of death worldwide, and nonfatal suicide attempts, which occur far more frequently, are a major source of disability and social and economic burden. Both have substantial genetic etiology, which is partially shared and partially distinct from that of related psychiatric disorders. Methods We conducted a genome-wide association study (GWAS) of 29,782 suicide attempt (SA) cases and 519,961 controls in the International Suicide Genetics Consortium (ISGC). The GWAS of SA was conditioned on psychiatric disorders using GWAS summary statistics via multitrait-based conditional and joint analysis, to remove genetic effects on SA mediated by psychiatric disorders. We investigated the shared and divergent genetic architectures of SA, psychiatric disorders, and other known risk factors. Results Two loci reached genome-wide significance for SA: the major histocompatibility complex and an intergenic locus on chromosome 7, the latter of which remained associated with SA after conditioning on psychiatric disorders and replicated in an independent cohort from the Million Veteran Program. This locus has been implicated in risk-taking behavior, smoking, and insomnia. SA showed strong genetic correlation with psychiatric disorders, particularly major depression, and also with smoking, pain, risk-taking behavior, sleep disturbances, lower educational attainment, reproductive traits, lower socioeconomic status, and poorer general health. After conditioning on psychiatric disorders, the genetic correlations between SA and psychiatric disorders decreased, whereas those with nonpsychiatric traits remained largely unchanged. Conclusions Our results identify a risk locus that contributes more strongly to SA than other phenotypes and suggest a shared underlying biology between SA and known risk factors that is not mediated by psychiatric disorders.Peer reviewe

    SARS-CoV-2 susceptibility and COVID-19 disease severity are associated with genetic variants affecting gene expression in a variety of tissues

    Variability in SARS-CoV-2 susceptibility and COVID-19 disease severity between individuals is partly due to genetic factors. Here, we identify 4 genomic loci with suggestive associations for SARS-CoV-2 susceptibility and 19 for COVID-19 disease severity. Four of these 23 loci likely have an ethnicity-specific component. Genome-wide association study (GWAS) signals in 11 loci colocalize with expression quantitative trait loci (eQTLs) associated with the expression of 20 genes in 62 tissues/cell types (range: 1:43 tissues/gene), including lung, brain, heart, muscle, and skin as well as the digestive system and immune system. We perform genetic fine mapping to compute 99% credible SNP sets, which identify 10 GWAS loci that have eight or fewer SNPs in the credible set, including three loci with one single likely causal SNP. Our study suggests that the diverse symptoms and disease severity of COVID-19 observed between individuals is associated with variants across the genome, affecting gene expression levels in a wide variety of tissue types

    Multiple Measures of Adiposity Are Associated with Mean Leukocyte Telomere Length in the Northern Finland Birth Cohort 1966

    Studies of leukocyte telomere length (LTL) and adiposity have produced conflicting results, and the relationship between body mass index (BMI) and telomere length throughout life remains unclear. We therefore tested association of adult LTL measured in 5,598 participants with: i) childhood growth measures (BMI and age at adiposity rebound (AR)); ii) change in BMI from childhood to adulthood and iii) adult BMI, waist-to-hip ratio (WHR), body adiposity index (BAI). Childhood BMI at AR was positively associated with LTL at 31 years in women (P = 0.041). Adult BMI and WHR in both men (P = 0.025 and P = 0.049, respectively) and women (P = 0.029 and P = 0.008, respectively), and BAI in women (P = 0.021) were inversely associated with LTL at 31 years. An increase in standardised BMI between early childhood and adulthood was associated with shorter adult LTL in women (P = 0.008). We show that LTL is inversely associated with multiple measures of adiposity in both men and women. Additionally, BMI increase in women from childhood to adulthood is associated with shorter telomeres at age 31, potentially indicating accelerated biological ageing
