Identification of Psychosis Risk and Diagnosis of First-Episode Psychosis: Advice for Clinicians. Psychol Res Behav Manag 2024; 17:1365-1383. [PMID: 38529082 PMCID: PMC10962362 DOI: 10.2147/prbm.s423865] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Accepted: 03/07/2024] [Indexed: 03/27/2024] Open
Abstract
Early detection of psychotic-spectrum disorders among adolescents and young adults is crucial, as the initial years after psychotic symptom onset encompass a critical period in which psychosocial and pharmacological interventions are most effective. Moreover, clinicians and researchers in recent decades have thoroughly characterized psychosis-risk syndromes, in which youth are experiencing early warning signs indicative of heightened risk for developing a psychotic disorder. These insights have created opportunities for intervention even earlier in the illness course, ideally culminating in the prevention or mitigation of psychosis onset. However, identification and diagnosis of early signs of psychosis can be complex, as clinical presentations are heterogeneous, and psychotic symptoms exist on a continuum. When a young person presents to a clinic, it may be unclear whether they are experiencing common, mild psychotic-like symptoms, early warning signs of psychosis, overt psychotic symptoms, or symptoms better accounted for by a non-psychotic disorder. Therefore, the purpose of this review is to provide a framework for clinicians, including those who treat non-psychotic disorders and those in primary care settings, for guiding identification and diagnosis of early psychosis within the presenting clinic or via referral to a specialty clinic. We first provide descriptions and examples of first-episode psychosis (FEP) and psychosis-risk syndromes, as well as assessment tools used to diagnose these conditions. Next, we provide guidance as to the differential diagnosis of conditions which have phenotypic overlap with psychotic disorders, while considering the possibility of co-occurring symptoms in which case transdiagnostic treatments are encouraged. Finally, we conclude with an overview of early detection screening and outreach campaigns, which should be further optimized to reduce the duration of untreated psychosis among youth.

Abstract
Autism Spectrum Disorder (ASD) is a neurodevelopmental condition characterized by challenges in social interaction and communication and the presence of restricted interests and repetitive behaviors. The importance of early detection of ASD and subsequent early intervention is well documented. Efforts have been made over the years to clarify ASD diagnostic criteria and develop predictive, accurate screening tools and evidence-based, standardized diagnostic instruments to aid in the identification of ASD. In this article, we review the most recent changes in ASD diagnostic criteria in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision, summarize evidence-based instruments for ASD screening and diagnostic evaluations as well as the assessment of co-occurring conditions in ASD, the impact of COVID-19 on ASD assessment, and directions for future research in the field of ASD assessment.

Evaluating the Effectiveness of Triiodothyronine Suppression and Withdrawal Versus Thyrogen Injections in Thyroid Cancer Assessments. Cureus 2023; 15:e51061. [PMID: 38269223 PMCID: PMC10806585 DOI: 10.7759/cureus.51061] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/25/2023] [Indexed: 01/26/2024] Open
Abstract
Objective This study aimed to evaluate the specificity and effectiveness of triiodothyronine (T3) suppression and withdrawal, as compared to the conventional diagnostic approach using Thyrogen recombinant thyroid-stimulating hormone (TSH) injections, in the assessment of thyroid cancer patients post-thyroidectomy. Methods In this retrospective study, 18 patients diagnosed with thyroid cancer at a tertiary care hospital (Mediclinic City Hospital) in Dubai were included. The patients underwent total thyroidectomy, iodine ablation, and neck ultrasound. The cohort's clinical characteristics were analyzed, and histopathological examination of thyroid nodules was performed. In this study, paired T-tests were applied to evaluate the before-and-after impact of T3 and Thyrogen treatments on TSH and thyroglobulin (TG) levels in individual patients. To further analyze the effectiveness of these treatments, independent T-tests were conducted, allowing for a comparison of TSH and TG levels between different treatment groups within the patient cohort. This approach provided a comprehensive assessment of the treatments' effects on key thyroid indicators. Additionally, the diagnostic accuracy of T3 withdrawal and Thyrogen post-test on TG levels was assessed using statistical measures including sensitivity, specificity, and predictive values. Results The cohort had a mean age of 42.1 years and a female predominance. Distinct clinical profiles were observed across different thyroid cancer subtypes. Histopathological analysis confirmed typical features of papillary carcinoma variants. Significant changes in TSH levels post-treatment were noted, with T3 treatments showing a marked increase in TSH and TG levels, although changes in TG levels were not always statistically significant. Diagnostic test evaluation showed a sensitivity of 77.78%, a specificity of 83.33%, and an overall accuracy of 80.00% for T3 withdrawal and Thyrogen post-test on TG. Conclusion The study provides comprehensive insights into the clinical profiles and treatment responses in thyroid cancer patients post-thyroidectomy. The effectiveness of T3 and Thyrogen treatments in altering TSH and TG levels was established, with significant implications for patient management. The diagnostic tests for T3 withdrawal and Thyrogen post-test on TG demonstrated high accuracy, underlining their clinical utility in the post-treatment evaluation of thyroid cancer patients.

Abstract
OBJECTIVES Diagnosing mental health challenges in bereavement is controversial; however, regardless of one's position on this matter, assessments of bereaved individuals continue to occur in clinical and research contexts. It is critical for evaluations to account for contextual factors that are unique to bereavement. This paper summarizes considerations for diagnosing depression in bereaved individuals, focusing on use of the six-item Hamilton Depression Rating Scale (HAM-D6). METHODS Following a literature review of the Hamilton Depression Rating Scale (HAM-D) and various versions, we summarized decision rules we used in scoring the HAM-D6 in a study of parents bereaved by cancer. We expanded on existing scoring guidelines for each of the HAM-D6 items, including depressed mood, work and activities, general somatic symptoms, guilt, psychic anxiety, and psychomotor retardation, and illustrated clinical distinctions and probes for assessors to consider through case examples from our research with bereaved parents. RESULTS Considerations for assessing depressive symptoms and behavior changes in the context of bereavement were summarized. Symptoms that may be diagnostic of depression in some populations may reflect other factors in the bereaved, such as a change in priorities, social expectations surrounding grief, or avoidance of grief activators. Nuanced factors are important for assessors to consider when administering the HAM-D6 to bereaved individuals. SIGNIFICANCE OF RESULTS Our sharing of these considerations is not intended to promote diagnosis of depression in bereavement but to highlight the unique contextual factors that distinguish symptoms of depression from common experiences of grievers when applying an assessment tool such as the HAM-D6. While validated measures can be constraining, they can have clinical utility; they may increase standardization in research, help clinicians communicate with each other, advance the field more generally to understand the varying struggles bereaved individuals experience, and systemically facilitate access to services via managed care.

Diagnostic assessment of autism in adults - current considerations in neurodevelopmentally informed professional learning with reference to ADOS-2. Front Psychiatry 2023; 14:1258204. [PMID: 37867776 PMCID: PMC10585137 DOI: 10.3389/fpsyt.2023.1258204] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2023] [Accepted: 09/18/2023] [Indexed: 10/24/2023] Open
Abstract
Services for the assessment and diagnosis of autism in adults have been widely criticized and there is an identified need for further research in this field. There is a call for diagnostic services to become more accessible, person-centered, neurodiversity affirming, and respectful. There is a need for workforce development which will increase capacity for diagnostic assessment and support for adults. ADOS-2 is a gold-standard diagnostic assessment tool for autism recommended in clinical guidelines. However, diagnostic procedures such as the ADOS-2 are rooted in the medical model and do not always sit comfortably alongside the neurodiversity paradigm or preferences of the autistic community. Training and educational materials need to account for the differences between these approaches and support clinicians to provide services which meet the needs of the adults they serve. The National Autism Implementation Team worked alongside ADOS-2 training providers to support clinicians in Scotland, to provide effective and respectful diagnostic assessment. The team engaged with clinicians who had attended ADOS training to identify areas of uncertainty or concern. Training materials were developed to support ADOS assessors to incorporate key principles including "nothing about us without us"; "difference not deficit"; "environment first"; "diagnosis matters," "language and mindsets matter"; and "a neurodevelopmental lens," to support the provision of neurodiversity affirming assessment practice. The National Autism Implementation Team also provided examples of actions which can be undertaken by clinicians to improve the assessment experience for those seeking a diagnosis. Training materials are based on research evidence, clinical experience, and the needs and wishes of autistic people.

Schizophrenia in autistic people with intellectual disabilities: Symptom manifestations and identification. JOURNAL OF APPLIED RESEARCH IN INTELLECTUAL DISABILITIES 2023; 36:1076-1091. [PMID: 37264713 DOI: 10.1111/jar.13127] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2022] [Revised: 03/17/2023] [Accepted: 05/17/2023] [Indexed: 06/03/2023]
Abstract
BACKGROUND The assessment of schizophrenia in autistic people with intellectual disabilities is challenging. This study aimed to explore the identification of schizophrenia in this population. METHODS Using data from a clinical multi-centre study, reported symptoms in 26 autistic individuals with intellectual disabilities diagnosed with co-occurring schizophrenia were explored. Scores on two checklists (Psychopathology in Autism Checklist [PAC], Aberrant Behaviour Checklist [ABC]) were compared with two comparison groups: autistic individuals with intellectual disabilities and other mental disorders (94), or no mental disorder (63). RESULTS Reported symptoms of schizophrenia in this population met the formal diagnostic criteria. For PAC/ABC scales, only PAC psychosis differed for the schizophrenia group. Among participants with schizophrenia, two were diagnosed with additional mental disorders. Elevated scores for anxiety and depression were common. CONCLUSIONS Emphasising core symptoms seems necessary when assessing co-occurring schizophrenia in autistic people with intellectual disabilities. The PAC may serve as a helpful screening tool.

Abstract
BACKGROUND Ambulatory diagnostic errors are increasingly being recognized as an important quality and safety issue, and while measures of diagnostic quality have been sought, tools to evaluate diagnostic assessments in the medical record are lacking. OBJECTIVE To develop and test a tool to measure diagnostic assessment note quality in primary care urgent encounters and identify common elements and areas for improvement in diagnostic assessment. DESIGN Retrospective chart review of urgent care encounters at an urban academic setting. PARTICIPANTS Primary care physicians. MAIN MEASURES The Assessing the Assessment (ATA) instrument was evaluated for inter-rater reliability, internal consistency, and findings from its application to EHR notes. KEY RESULTS ATA had reasonable performance characteristics (kappa 0.63, overall Cronbach's alpha 0.76). Variability in diagnostic assessment was seen in several domains. Two components of situational awareness tended to be well-documented ("Don't miss diagnoses" present in 84% of charts, red flag symptoms in 87%), while Psychosocial context was present only 18% of the time. CONCLUSIONS The ATA tool is a promising framework for assessing and identifying areas for improvement in diagnostic assessments documented in clinical encounters.

Diagnostic Concordance between Research and Clinical-Based Assessments of Psychiatric Comorbidity in Anorexia Nervosa. J Clin Med 2022; 11:jcm11247419. [PMID: 36556034 PMCID: PMC9782669 DOI: 10.3390/jcm11247419] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Revised: 12/09/2022] [Accepted: 12/12/2022] [Indexed: 12/23/2022] Open
Abstract
The literature has reported poor concordance in the assessment of psychiatric conditions, and inhomogeneity in the prevalence of psychiatric comorbidities in Anorexia Nervosa (AN). We aimed to investigate concordance level between clinicians' and researchers' diagnoses of psychiatric comorbidity in AN and differences in eating and general psychopathology between patients with and without psychiatric comorbidity assessed by clinicians versus researchers. A clinical psychiatrist interviewed 122 patients with AN; then a researcher administered the Structured and Clinical Interview for DSM-5 (SCID-5). Participants completed the Eating Disorder Examination Questionnaire (EDE-Q), the State-Trait Anxiety Inventory (STAI), and the Beck Depression Inventory (BDI). The agreement between clinicians and researchers was poor for all diagnoses but obsessive-compulsive disorder and substance use disorder. Patients with comorbid disorders diagnosed by researchers reported more severe eating and general psychopathology than those without SCID-comorbidity. The differences between patients with and without comorbidities assessed by a clinician were smaller. Two approaches to psychiatry comorbidity assessment emerged: SCID-5 diagnoses yield a precise and rigorous assessment, while clinicians tend to consider some symptoms as secondary to the eating disorder rather than as part of another psychiatric condition, seeing the clinical picture as a whole. Overall, the study highlights the importance of carefully assessing comorbidity in AN.

Psychiatric diagnostic dilemmas among people with intellectual and developmental disabilities. JOURNAL OF INTELLECTUAL DISABILITY RESEARCH : JIDR 2022; 66:805-816. [PMID: 35974452 DOI: 10.1111/jir.12972] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Revised: 07/21/2022] [Accepted: 07/27/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Research regarding the accuracy of co-morbid psychiatric diagnoses in individuals with intellectual and developmental disabilities (IDD) is sparse. Yet correct diagnostic assignment is vital so that effective and appropriate treatment can be implemented, especially for the large numbers of individuals requiring expensive and restrictive behavioural health crisis services. METHOD A retrospective review of de-identified data from multidisciplinary specialty team assessments completed for 50 individuals with ID (IntellectualDisability) with and without ASD and unresolved behavioural health challenges was conducted. The accuracy and reliability of the psychiatric diagnoses upon referral were compared with the diagnoses after the comprehensive team evaluation, and within-individual diagnostic agreement was calculated. The agreement between the Mood and Anxiety Semi-Structured interview tool (MASS) and the full team evaluation was also calculated. The influence of demographic and clinical characteristics on diagnostic agreement was explored. RESULTS The most common chief complaints upon referral were aggression to others and self-injurious behaviour. Individuals were taking a median of six medications (interquartile range: 5 to 7); 80% were taking an antipsychotic medication. The most common medical conditions were constipation (70%) and gastroesophageal reflux disease (52%). Measures of interrater reliability of the referral diagnoses with the team assessment were below 0.5 (kappa range: -0.04 to 0.39), with the exception of ruling out dementia (kappa = 0.85). The interrater reliability estimates for the MASS evaluations for depression and anxiety were higher (kappa = 0.69 and 0.64) and reflected higher sensitivity and PPV. The odds of any referral diagnosis being confirmed by team evaluation were low: 0.25 (range: 0 to 0.67). The level of diagnostic agreement for each patient was not significantly attributable to demographic or clinical characteristics, although effect sizes indicate a possible positive relationship to age and the number of prescribed psychotropic medications at referral. CONCLUSION Individuals in the current study had serious psychiatric and behavioural problems despite psychiatric care in their communities. The majority of psychiatric diagnoses provided upon referral were not supported by the multidisciplinary specialty team's assessment. In addition to possible diagnostic inaccuracy, the group in the study suffered from multiple medical co-morbidities and were exposed to polypharmacy. Results emphasise the importance of multidisciplinary evaluation by clinicians with expertise in neurodevelopmental disabilities when people with ID with and without ASD have complex behavioural health needs that are unresponsive to usual care. In addition, based on agreement with the full team evaluation, the MASS shows promise as an assessment tool, especially with regards to identifying anxiety and depression.

Abstract
In many cultures, people use the concept of spirit possession to explain abrupt changes in behavior and identity or problems with affect regulation. High incidence of traumatic experiences are also found among "possession" victims but there are few studies exploring in detail their clinical presentations. This study reports the symptoms of two women with a history of sexual abuse, labeled in their religious communities as possessed, and subjected to exorcisms. Following a thorough clinical assessment, interpretative phenomenological analysis was used to explore their meaning-making and help-seeking behavior. Accepting the demonic reappraisal of trauma-related symptoms and interventions offered by clergy contributed to receiving social support but discouraged them from seeking diagnostic consultations and trauma-focused therapy, leading to their continued symptoms. This justifies the need for educating religious leaders in recognizing and understanding basic psychopathological symptoms.

Abstract
Dynamic Bayesian networks (DBNs; Reye, 2004) are a promising tool for modeling student proficiency under rich measurement scenarios (Reichenberg, 2018). These scenarios often present assessment conditions far more complex than what is seen with more traditional assessments and require assessment arguments and psychometric models capable of integrating those complexities. Unfortunately, DBNs remain understudied and their psychometric properties relatively unknown. The current work aimed at exploring the properties of DBNs under a variety of realistic psychometric conditions. A Monte Carlo simulation study was conducted in order to evaluate parameter recovery for DBNs using maximum likelihood estimation. Manipulated factors included sample size, measurement quality, test length, the number of measurement occasions. Results suggested that measurement quality has the most prominent impact on estimation quality with more distinct performance categories yielding better estimation. From a practical perspective, parameter recovery appeared to be sufficient with samples as low as N = 400 as long as measurement quality was not poor and at least three items were present at each measurement occasion. Tests consisting of only a single item required exceptional measurement quality in order to adequately recover model parameters.

D-Dimer Tests in the Emergency Department: Current Insights. Open Access Emerg Med 2021; 13:465-479.

Abstract
In the Emergency Medicine setting, D-dimer is currently employed in the diagnostic assessment of suspected venous thromboembolism and aortic syndrome. The nonspecific symptoms reported by patients, like chest pain, dyspnea or syncope, uncover a wide range of differential diagnosis, spanning from mild to life-threatening conditions. Therefore, we assumed the perspective of the Emergency Physician and, in this narrative review, we reported a brief presentation of the epidemiology of these symptoms and the characteristics of patients, in whom we could suspect the aforementioned pathologies. We also reported in which patients D-dimer gives useful information. In fact, when the probability of the disease is high, the D-dimer level is futile. On the contrary, given the low specificity of the test, when the probability of the disease is very low, a false-positive value of the D-dimer only increases the risk of overtesting. Patients with low to moderate probability really benefit from the D-dimer testing, in order to prevent the execution of expensive and potentially dangerous imaging tests. In the second part of the review, we focused on the prognostic value of the test in septic patients. The early prognostic stratification of septic patients remains a challenge for the Emergency Physician, in the absence of a definite biomarker or score to rely on. Therefore, we need several parameters for the early identification of patients at risk of an adverse prognosis and the D-dimer may play a role in this demanding task. SARS COVID-19 patients represent an emerging reality, where the role of the D-dimer for prognostic stratification could be relevant. In fact, in patients with severe forms of this disease, the D-dimer reaches very high values, which appear to parallel the course of respiratory failure. Whether the test may add useful information for the management of these patients remains to be determined.

Abstract
BACKGROUND Question-based computational language assessments (QCLA) of mental health, based on self-reported and freely generated word responses and analyzed with artificial intelligence, is a potential complement to rating scales for identifying mental health issues. This study aimed to examine to what extent this method captures items related to the primary and secondary symptoms associated with Major Depressive Disorder (MDD) and Generalized Anxiety Disorder (GAD) described in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). We investigated whether the word responses that participants generated contained information of all, or some, of the criteria that define MDD and GAD using symptom-based rating scales that are commonly used in clinical research and practices. METHOD Participants (N = 411) described their mental health with freely generated words and rating scales relating to depression and worry/anxiety. Word responses were quantified and analyzed using natural language processing and machine learning. RESULTS The QCLA correlated significantly with the individual items connected to the DSM-5 diagnostic criteria of MDD (PHQ-9; Pearson's r = 0.30-0.60, p < 0.001) and GAD (GAD-7; Pearson's r = 0.41-0.52, p < 0.001; PSWQ-8; Spearman's r = 0.52-0.63, p < 0.001) for respective rating scales. Items measuring primary criteria (cognitive and emotional aspects) yielded higher predictability than secondary criteria (behavioral aspects). CONCLUSION Together these results suggest that QCLA may be able to complement rating scales in measuring mental health in clinical settings. The approach carries the potential to personalize assessments and contributes to the ongoing discussion regarding the diagnostic heterogeneity of depression.

Abstract
The range and severity of developmental delays vary, and a systematic approach to ensuring early detection for early intervention is essential. The formative years are considered critical for nurturing and maximising developmental potential. In this article, the authors describe a clinical approach to developmental delay within resource-constrained environments of South Africa. The article unpacks the history and examination, developmental screening, surveillance and diagnostic assessment and social determinants of health. For timely interventions to occur, early and accurate assessment is necessary. Medical officers and other health professionals such as nurses, general practitioners and therapists working in low-resourced contexts may use this information in their approach to the assessment of developmental delay.

Proficiency Testing of Metagenomics-Based Detection of Food-Borne Pathogens Using a Complex Artificial Sequencing Dataset. Front Microbiol 2020; 11:575377.

Abstract
Metagenomics-based high-throughput sequencing (HTS) enables comprehensive detection of all species comprised in a sample with a single assay and is becoming a standard method for outbreak investigation. However, unlike real-time PCR or serological assays, HTS datasets generated for pathogen detection do not easily provide yes/no answers. Rather, results of the taxonomic read assignment need to be assessed by trained personnel to gain information thereof. Proficiency tests are important instruments of validation, harmonization, and standardization. Within the European Union funded project COMPARE [COllaborative Management Platform for detection and Analyses of (Re-) emerging and foodborne outbreaks in Europe], we conducted a proficiency test to scrutinize the ability to assess diagnostic metagenomics data. An artificial dataset resembling shotgun sequencing of RNA from a sample of contaminated trout was provided to 12 participants with the request to provide a table with per-read taxonomic assignments at species level and a report with a summary and assessment of their findings, considering different categories like pathogen, background, or contaminations. Analysis of the read assignment tables showed that the software used reliably classified the reads taxonomically overall. However, usage of incomplete reference databases or inappropriate data pre-processing caused difficulties. From the combination of the participants' reports with their read assignments, we conclude that, although most species were detected, a number of important taxa were not or not correctly categorized. This implies that knowledge of and awareness for potentially dangerous species and contaminations need to be improved, hence, capacity building for the interpretation of diagnostic metagenomics datasets is necessary.

Abstract
Objective The 22-item Sinonasal Outcome Test (SNOT-22) is a trusted measure of symptom severity in chronic rhinosinusitis. The European Position Paper on Rhinosinusitis (EPOS) provides widely accepted diagnostic criteria, which include sinonasal symptoms, their duration, and imaging results. Our objective was to compare these approaches to assessing symptoms to determine if either was more indicative of radiologic findings, to support decisions in telehealth. Study Design Observational outcomes study. Setting Tertiary care center. Methods In total, 162 consecutive patients provided a structured sinonasal history, completed the SNOT-22, and underwent sinus computed tomography (CT) within 1 month. SNOT-22 scores, EPOS-defined symptom sets, and Lund-Mackay results were assessed. To facilitate direct comparisons, we performed stepwise evaluations of sinonasal symptoms alone and combined with duration. The discriminatory capacity for imaging results was determined through areas under the receiver operating characteristic curves (ROC-AUC) for dichotomous outcomes and ordinal regression for multilevel outcomes. Results In ROC-AUC analyses, SNOT-22 and EPOS-defined symptoms had similar discriminatory capacity for Lund-Mackay scores, regardless of duration. Within ordinal regression analyses, SNOT-22 nasal scores were significantly associated with Lund-Mackay scores, while EPOS-defined nasal symptoms were not statistically significantly related. Conclusions SNOT-22 nasal scores and EPOS-defined nasal symptoms may have similar associations with imaging results when assessed via ROC-AUC, while SNOT-22 may have more association within ordinal data. Understanding the implications of discrete patterns of symptoms may confer benefit, particularly when in-person and fiberoptic exams are limited.

Abstract
BACKGROUND Full parental understanding of a child's diagnosis of a developmental disability is critical to be able to ensure the best health outcome for their child. Yet factors that parents perceived as influencing their comprehension during the final diagnostic meeting have not been well identified. METHOD This study used a qualitative interpretive description approach. Seventeen parents were interviewed who received a child's developmental diagnosis from one of the clinical multidisciplinary teams located in northern British Columbia. The interviews focused on the factors that played a role in facilitating or impeding the parents' understanding of their child's diagnosis, and on the identification of factors that influenced the way in which the child's clinical recommendations were pursued. RESULTS Two overarching themes with nine subthemes emerged from parents' reported experiences of receiving their child's developmental diagnosis. The themes and subthemes included (a) clinical encounter (including the subthemes structural considerations, professional diversity and new insights, questions regarding the assessment process, and validation) and (b) manner of the delivery of the diagnosis (emotional impact, impact on parenting practices, professionalism, professional language, and quantity of information). CONCLUSIONS Parents' accounts established and clarified the positive and negative parental determinants that aided or challenged their ability to understand their child's developmental diagnosis during the final clinical interaction with the multidisciplinary team.

The Development of a Multidimensional Diagnostic Assessment With Learning Tools to Improve 3-D Mental Rotation Skills. Front Psychol 2020; 11:305. [PMID: 32174870 PMCID: PMC7054440 DOI: 10.3389/fpsyg.2020.00305] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2019] [Accepted: 02/10/2020] [Indexed: 11/23/2022] Open
Abstract
This study reported on development and evaluation of a learning program that integrated a multidimensional diagnostic assessment with two different learning interventions with the aim to diagnose and improve three-dimensional mental rotation skills. The multidimensional assessment was built upon the Diagnostic Classification Model (DCM) framework that can report the binary mastery on each specific rotation skill. The two learning interventions were designed to train students to use a holistic rotation strategy and a combined analytic and holistic strategy, respectively. The program was evaluated through an experiment paired with multiple exploratory and confirmatory statistical analysis. Particularly, the recently proposed joint models for response times and response accuracy within dynamic DCM framework is applied to assess the effectiveness of the learning interventions. Compared with the traditional assessment on spatial skills, where the tests are timed and number correct is reported as a measure for test-takers' performances, the developed dynamic diagnostic assessment can provide an informative estimate of the learning trajectory for each participant in terms of the strengths and weaknesses in four fine-grained spatial rotation skills over time. Compared with an earlier study that provided initial evidence of the effectiveness of building a multidimensional diagnostic assessment with training tools, the present study improved the assessment and learning intervention design. Using both response times and response accuracy, thus current study additionally evaluated the newly developed program by investigating the effectiveness of two interventions across gender, country and rotation strategy.

Abstract
Digital games offer an appealing environment for assessing student proficiencies, including skills and misconceptions in a diagnostic setting. This paper proposes a dynamic Bayesian network modeling approach for observations of student performance from an educational video game. Drawing from and advancing methods in dynamic Bayesian networks, cognitive diagnostic modeling, and analysis of process data, a Bayesian approach to model construction, calibration, and use in facilitating inferences about students on the fly is described, and implemented in the context of an educational video game.

Abstract
The aims of this paper are: to provide a comprehensive introduction to eDia, an online diagnostic assessment system; to show how the use of technology can contribute to solve certain crucial problems in education by supporting the personalization of learning; and to offer a general reference for further eDia-based studies. The primary function for which the system is designed is to provide regular diagnostic feedback in three main domains of education, reading, mathematics, and science, from the beginning of schooling to the end of the 6 years of primary education. The cognitive foundations of the system, the assessment frameworks, are based on a three-dimensional approach in each domain, distinguishing the psychological (reasoning), the application, and the disciplinary (curricular content) dimensions of learning. The frameworks have been carefully mapped into item banks containing over a 1,000 innovative (multimedia-supported) items in each dimension. The online assessments were piloted, and the system has been operating in experimental mode in over 1,000 schools for several years. This paper outlines the theoretical foundations of the eDia system and summarizes how results from research on the cognitive sciences, learning and instruction, and technology-based assessment have been integrated into a working system designed to assess a large population of students. The paper describes the main functions of eDia and discusses how it supports item writing, constructing tests, online test delivery, automated scoring, data processing, scaling and the provision of feedback both for students and teachers. It shows how diagnostic assessments can be implemented in school practice to facilitate differentiated instruction through regular measurements and to provide instruments for teachers to make formative assessments. Beyond its main function (supporting development toward personalizing education), the eDia platform has been used for assessments in a number of areas from pre-school to higher education both in Hungary and in a number of other countries as well. The paper also reviews results from eDia-based studies and highlights how technology-based assessment extends the possibilities of educational research by making more constructs measurable.

Abstract
Background: Individuals with intellectual disability respond differently to traumatic events, compared to the general population, which makes post-traumatic stress disorder (PTSD) symptoms difficult to recognize. The current study aims to examine the presence of undetected PTSD among individuals with intellectual disability and a known history of trauma exposure. Method: Nine individuals, who have not previously been diagnosed with PTSD, were evaluated for PTSD symptoms through case reports, which include descriptions of medical history, symptoms and behavior described in the former diagnostic reports, potential traumatic experiences, current symptoms and behavior in accordance to the Lancaster and North Gate Trauma Scale, and PTSD criteria from DM-ID. Results: Four out of the nine participants met the DM-ID criteria for PTSD. Conclusions: The current findings highlight the importance of including cognitive impairment and developmental level in the screening, referral and treatment process of PTSD.

Abstract
The purpose of this study was to examine rates and patterns of non-attention-deficit/hyperactivity disorder (non-ADHD) psychiatric diagnoses among a large group of 1st-year college students with and without ADHD. A total of 443 participants, including 214 men and 229 women ranging in age from 18 to 22 years of age (M = 18.2), were recruited from 9 colleges involved in a large-scale, multisite longitudinal investigation. Non-Hispanic Caucasian students represented 67.5% of the total sample. A comprehensive multimethod assessment approach was used in conjunction with expert panel review to determine both ADHD and comorbidity status. Significantly higher rates of overall comorbidity were found among college students with well-defined ADHD, with 55.0% exhibiting at least one comorbid diagnosis and 31.8% displaying two or more, relative to the corresponding rates of non-ADHD diagnoses among Comparison students, which were 11.2% and 4.0%, respectively. These differences in overall comorbidity rates were, in large part, attributable to the increased presence of depressive and anxiety disorders, especially major depressive disorder (active or in partial remission) and generalized anxiety disorder, among the students with ADHD. Within the ADHD group, differential comorbidity rates were observed as a function of ADHD presentation type and gender but not ethnic/racial diversity status. The current findings fill a gap in the literature and shed new light on the rates and patterns of comorbidity among emerging adults with ADHD in their 1st year of college. Implications for providing clinical and support services to college students with ADHD are discussed.

Abstract
OBJECTIVES To measure older adults acceptability of dementia screening and assess screening test results of a racially diverse sample of older primary care patients in the United States. DESIGN Cross-sectional study of primary care patients aged 65 and older. SETTING Urban and suburban primary care clinics in Indianapolis, Indiana, in 2008 to 2009. PARTICIPANTS Nine hundred fifty-four primary care patients without a documented diagnosis of dementia. MEASUREMENTS Community Screening Instrument for Dementia, the Mini-Mental State Examination, and the Telephone Instrument for Cognitive Screening. RESULTS Of the 954 study participants who consented to participate, 748 agreed to be screened for dementia and 206 refused screening. The overall response rate was 78.4%. The positive screen rate of the sample who agreed to screening was 10.2%. After adjusting for demographic differences the following characteristics were still associated with increased likelihood of screening positive for dementia: age, male sex, and lower education. Patients who believed that they had more memory problems than other people of their age were also more likely to screen positive for dementia. CONCLUSION Age and perceived problems with memory are associated with screening positive for dementia in primary care.

OBJECTIVE To describe adherence to international guidelines for chronic heart failure (CHF) management concerning diagnostics, pharmacological treatment and self-care behaviour in primary health care. DESIGN A cross-sectional descriptive study of patients with CHF, using data obtained from medical records and a postal questionnaire. SETTING Three primary health care centres in Sweden. SUBJECTS Patients with a CHF diagnosis registered in their medical record. MAIN OUTCOME MEASURES Adherence to recommended diagnostic tests and pharmacological treatment by the European Society of Cardiology guidelines and self-care behaviour, using the European Heart Failure Self-care Behaviour Scale (EHFScBS-9). RESULTS The 155 participating patients had a mean age of 79 (SD9) years and 89 (57%) were male. An ECG was performed in all participants, 135 (87%) had their NT-proBNP measured, and 127 (82%) had transthoracic echocardiography performed. An inhibitor of the renin angiotensin system (RAS) was prescribed in 120 (78%) patients, however only 45 (29%) in target dose. More men than women were prescribed RAS-inhibition. Beta blockers (BBs) were prescribed in 117 (76%) patients, with 28 (18%) at target dose. Mineralocorticoidreceptor antagonists were prescribed in 54 (35%) patients and daily diuretics in 96 (62%). The recommended combination of RAS-inhibitors and BBs was prescribed to 92 (59%), but only 14 (9%) at target dose. The mean score on the EHFScBS-9 was 29 (SD 6) with the lowest adherence to daily weighing and consulting behaviour. CONCLUSION Adherence to guidelines has improved since prior studies but is still suboptimal particularly with regards to medication dosage. There is also room for improvement in patient education and self-care behaviour.

Financing Cocaine Use in a Homeless Population. Behav Sci (Basel) 2017; 7:bs7040074.

Abstract
Background: Cocaine use is highly prevalent among homeless populations, yet little is known about how it is financed. This study examined associations of income sources with cocaine use and financing of drugs in a longitudinal evaluation of a homeless sample. Methods: A homeless sample was recruited systematically in St. Louis in 1999–2001 and longitudinally assessed annually over two years using the Diagnostic Interview Schedule and the Homeless Supplement, with urine drug testing. Results: More than half (55%) of participants with complete follow-up data (N = 255/400) had current year cocaine use. Current users spent nearly $400 (half their income) in the last month on drugs at baseline. Benefits, welfare, and disability were negatively associated and employment and income from family/friends, panhandling, and other illegal activities were positively associated with cocaine use and monetary expenditures for cocaine. Conclusions: Findings suggest that illegal and informal income-generating activities are primary sources for immediate gratification with cocaine use and public entitlements do not appear to be primary funding sources used by homeless populations. Policy linking drug testing to benefits is likely to have little utility, and public expenditures on measures to unlink drug use and income might be more effectively used to fund employment and treatment programs.

Abstract
Approximately 75% of bladder cancers are non-muscle-invasive bladder cancer (NMIBC), and 50% of NMIBC patients who are treated with transurethral resection (TUR) have a recurrence of the disease and 5-25% of these patients progressed to muscle-invasive disease after repeated recurrences. NMIBC patients receive various treatments aimed at reducing disease recurrence and progression. Although the recurrence rate of disease remains above target, thus increasing treatment cost, the true rate of recurrence after the primary surgery is controversial. Recurrences can be categorized as either true recurrence due to aggressive tumor biology and implantation of floating cancer cells or false recurrence such as small, flat, or carcinoma in situ lesions overlooked in the primary procedure. Here we discuss new diagnostic methods and treatment options to improve outcomes and reduce recurrence rates in NMIBC.

Abstract
Differences in the social limitations of girls compared to boys on the autism spectrum are still poorly understood. Impaired social-emotional reciprocity is a core diagnostic criterion for an autism spectrum disorder. This study compares sex differences in reciprocal behaviour in children with autism spectrum disorder (32 girls, 114 boys) and in typically developing children (24 girls, 55 boys). While children with autism spectrum disorder showed clear limitations in reciprocal behaviour compared to typically developing children, sex differences were found only in the autism spectrum disorder group: girls with autism spectrum disorder had higher reciprocity scores than boys with autism spectrum disorder. However, compared to typically developing girls, girls with autism spectrum disorder showed subtle differences in reciprocal behaviour. The sex-specific response patterns in autism spectrum disorder can inform and improve the diagnostic assessment of autism in females.

Abstract
OBJECTIVES To evaluate whether Asian (Korean children) populations can be validly diagnosed with autism spectrum disorder (ASD) using Western-based diagnostic instruments and criteria based on Diagnostic and Statistical Manual on Mental Disorders, 5th edition (DSM-5). METHODS Participants included an epidemiologically ascertained 7-14-year-old (N = 292) South Korean cohort from a larger prevalence study (N = 55,266). Main outcomes were based on Western-based diagnostic methods for Korean children using gold standard instruments, Autism Diagnostic Interview-Revised, and Autism Diagnostic Observation Schedule. Factor analysis and ANOVAs were performed to examine factor structure of autism symptoms and identify phenotypic differences between Korean children with ASD and non-ASD diagnoses. RESULTS Using Western-based diagnostic methods, Korean children with ASD were successfully identified with moderate-to-high diagnostic validity (sensitivities/specificities ranging 64%-93%), strong internal consistency, and convergent/concurrent validity. The patterns of autism phenotypes in a Korean population were similar to those observed in a Western population with two symptom domains (social communication and restricted and repetitive behavior factors). Statistically significant differences in the use of socially acceptable communicative behaviors (e.g., direct gaze, range of facial expressions) emerged between ASD versus non-ASD cases (mostly p < 0.001), ensuring that these can be a similarly valid part of the ASD phenotype in both Asian and Western populations. CONCLUSIONS Despite myths, biases, and stereotypes about Asian social behavior, Asians (at least Korean children) typically use elements of reciprocal social interactions similar to those in the West. Therefore, standardized diagnostic methods widely used for ASD in Western culture can be validly used as part of the assessment process and research with Koreans and, possibly, other Asians.

Abstract
Community-based mental health (CMH) services play an important, but relatively understudied role in the identification and treatment of youth with autism spectrum disorder (ASD) who may be receiving care for other psychiatric conditions. Little is known about the role of standardized ASD assessment measures administered by providers working in generalist community-based mental health (CMH) settings. This pilot study extracted data from three CMH clinics to examine the use of the Autism Diagnostic Observation Schedule (ADOS) by 17 CMH providers who received ASD assessment training with 62 youth (Mean = 10.69 years) referred for an ASD diagnostic evaluation. Results indicated that 57% of youths assessed ultimately received an ASD diagnosis. All cases given a final ASD diagnosis were classified as "Autism" or "ASD" on the ADOS. Seventy percent of youth who did not receive a final ASD diagnosis were classified as "Non-Spectrum" on the ADOS. In these false positive cases, report narratives indicated that social communication difficulties identified on the ADOS were explained by symptoms of other mental health conditions (e.g., ADHD, anxiety). Future research is needed to examine the utility of the ADOS when used by CMH providers to facilitate CMH capacity to identify ASD.

Abstract
Despite the inclusion of nonsuicidal self-injury disorder (NSSID) in the DSM-5, research on NSSID is limited and no studies have examined the full set of DSM-5 NSSID diagnostic criteria. Thus, this study examined the reliability and validity of a new structured diagnostic interview for NSSID (the Clinician-Administered NSSI Disorder Index; CANDI) and provides information on the clinical characteristics and features of DSM-5 NSSID. Data on the interrater reliability, internal consistency, and construct validity of the CANDI and associated characteristics of NSSID were collected in a community sample of young adults (N = 107) with recent recurrent NSSI (≥10 lifetime episodes of NSSI, at least one episode in the past year). Participants completed self-report measures of NSSI characteristics, psychopathology, and emotion dysregulation, as well as diagnostic interviews of borderline personality disorder (BPD) and lifetime mood, anxiety, and substance use disorders. The CANDI demonstrated good interrater reliability and adequate internal consistency. Thirty-seven percent of participants met criteria for NSSID. NSSID was associated with greater clinical and diagnostic severity, including greater NSSI versatility, greater emotion dysregulation and psychopathology, and higher rates of BPD, bipolar disorder, posttraumatic stress disorder, social anxiety disorder, and alcohol dependence. Findings provide support for the reliability, validity, and feasibility of the CANDI.

Abstract
AIM To study the socio-demographic and psychosocial risk factors of families presenting with their children for a diagnostic developmental assessment. METHODS Socio-demographic details of children who had a multidisciplinary developmental assessment with the Child Assessment Team at Campbelltown Hospital between January 2009 and December 2010 were collated and compared with census data. RESULTS In 2009 and 2010, 277 families were seen by the Child Assessment Team. A detailed socio-demographic profile was available for 251 (91%) families. Parents seen in the clinic were more likely to be younger, single, born overseas, have less post-school education, identify as Aboriginal and/or live in public housing compared with the district rates. CONCLUSIONS Families presenting to the developmental clinic have more socio-economic disadvantage compared with the referring district. This has implications for service delivery and clinical presentation, and highlights the importance of the social worker's role in a developmental diagnostic team.

Abstract
A number of researchers have proposed adding an increasing number of subthreshold variants of major depressive disorder (MDD) as new mood disorder. However, this research has suffered from a number of theoretical and methodological flaws that the current investigation has attempted to address. Individuals with MDD (n = 470) were compared with individuals with subthreshold MDD (n = 57). Individuals with MDD reported consistently more severe symptoms, albeit of small magnitude, as well as differences in comorbidity with only two disorders. Results also indicated that diagnosis did not significantly predict rate of symptom change when MDD was compared with its subthreshold variant. Taken together, the aforementioned evidence suggests that small differences exist between MDD and its subthreshold variant. In addition, the extent to which the latter serves as useful analogs for the former may depend upon the variables under study.

Abstract
Over 80% of all heart failure patients are 65 years and older. The diagnosis and management of heart failure in older adults can be challenging. However, with the correct clinical skill and experience, most geriatric heart failure can be properly diagnosed and managed. Management of geriatric heart failure can be simplified by following this useful mnemonic: DEFEAT Heart Failure. This covers the essential aspects of geriatric heart failure management: Diagnosis, Etiology, Fluid, Ejection fraAction, and Treatment. The process begins with a clinical Diagnosis, which must be established, before ordering an echocardiogram, as nearly half of all geriatric heart failure patients have normal left ventricular ejection fraction. Because heart failure is a syndrome and not a disease, an underlying Etiology must be sought and determined. Determination of the Fluid volume status by careful examination of the external jugular veins in the neck is vital to achieve euvolemia. An echocardiography should be ordered to obtain left ventricular Ejection frAction to assess prognosis and guide Therapy. However, if left ventricular ejection fraction cannot be determined, as in many developing nations, all geriatric heart failure patients should be treated as if they have low ejection fraction, and should be prescribed an angiotensin-converting enzyme inhibitor and a beta-blocker. Diuretic and digoxin should be prescribed for all symptomatic patients with heart failure. An aldosterone antagonist may be used in select patients with advanced systolic heart failure, carefully avoiding hyperkalemia.

Abstract
In the past, a German Computerized Adaptive Test, based on Item Response Theory (IRT), was developed for purposes of assessing the construct depression [Computer-adaptive test for depression (D-CAT)]. This study aims at testing the feasibility and validity of the real computer-adaptive application.The D-CAT, supplied by a bank of 64 items, was administered on personal digital assistants (PDAs) to 423 consecutive patients suffering from psychosomatic and other medical conditions (78 with depression). Items were adaptively administered until a predetermined reliability (r > or = 0.90) was attained. For validation purposes, the Hospital Anxiety and Depression Scale (HADS), the Centre for Epidemiological Studies Depression (CES-D) scale, and the Beck Depression Inventory (BDI) were administered. Another sample of 114 patients was evaluated using standardized diagnostic interviews [Composite International Diagnostic Interview (CIDI)].The D-CAT was quickly completed (mean 74 seconds), well accepted by the patients and reliable after an average administration of only six items. In 95% of the cases, 10 items or less were needed for a reliable score estimate. Correlations between the D-CAT and the HADS, CES-D, and BDI ranged between r = 0.68 and r = 0.77. The D-CAT distinguished between diagnostic groups as well as established questionnaires do.The D-CAT proved an efficient, well accepted and reliable tool. Discriminative power was comparable to other depression measures, whereby the CAT is shorter and more precise. Item usage raises questions of balancing the item selection for content in the future.
