RESUMO

BACKGROUND: Mental health problems and suicide ideation are common in adolescents. Early detection of these issues could prevent the escalation of mental health-related symptoms in the long term. Moreover, characterizing different profiles of prevalent symptoms in conjunction with emotional regulation strategies could guide the design of specific interventions. The use of web-based screening (WBS) tools has been regarded as a suitable strategy to timely detect symptomatology while improving the appeal, cost, timeliness, and reach of detection in young populations. However, the evidence regarding the accuracy of these approaches is not fully conclusive. OBJECTIVE: The study aims (1) to examine the capability of a WBS to identify adolescents with psychiatric symptoms and suicidality and (2) to characterize the mental health profiles of a large sample of adolescents using WBS. METHODS: A total of 1599 Latin American Spanish-speaking adolescents (mean age 15.56, SD 1.34 years), consisting of 47.3% (n=753) female, 98.5% Chilean (n=1570), and 1.5% Venezuelan (n=24) participants, responded to a mental health WBS. A randomized subsample of participants also responded to the Mini International Neuropsychiatric Interview for Children and Adolescents (MINI-KID). McNemar χ2 and receiver-operating characteristic curves tested the detection accuracy of WBS contrasted with the MINI-KID. Latent profile analyses explored the symptomatic and emotional regulation profiles of participants. RESULTS: Both measures showed an adequate level of agreement (area under the curve per symptom domain ranging from 0.70 to 0.89); however, WBS yielded a higher prevalence than MINI-KID for all psychiatric symptoms, except suicide ideation and depression. Latent profile analyses yielded 4 profiles-one of them presented elevated psychopathological symptoms, constituting 11% of the sample (n=175). Rumination (odds ratio [OR] 130.15, 95% CI 51.75-439.89; P<.001), entrapment (OR 96.35, 95% CI 29.21-317.79; P<.001), and defeat (OR 156.79, 95% CI 50.45-487.23; P<.001) contributed significantly to the prediction of latent profile memberships, while cognitive reappraisal did not contribute to the prediction of any latent profile memberships, and expressive suppression was only associated to profile-2 membership. CONCLUSIONS: WBS is acceptable for the timely detection of adolescents at risk of mental health conditions. Findings from the symptomatic and emotional regulation profiles highlight the need for comprehensive assessments and differential interventions.

RESUMO

INTRODUCTION: Malnutrition risk (MR) in older adults with neurological disorders is high, but there is little evidence for validated screening tools in this group, as well as for the clinical and socioeconomic factors associated with a high MR. OBJECTIVES: To determine the association of MR using the Malnutrition Universal Screening Tool (MUST) with mortality and length of stay (LOS) in older adults with neurological diseases. Secondarily, the association of clinical, and socioeconomic factors with MR and clinical outcomes was sought. METHODS: A retrospective cohort study was carried out at a third-level neurological disease referral center in Mexico. All patients older than 60 years admitted from January 2017 to December 2018 were considered. MUST, clinical and socioeconomic factors were assessed at hospital admission. Outcomes were followed up to hospital discharge or a maximum of 6 months. RESULTS: A total of 765 patients were included, of whom 24.7% (n = 189) were at high risk. A high MR was independently associated with mortality (OR 3.09; 95% CI 1.60-5.98, p = .001) and LOS >14 days (OR 4.38; 95% CI 2.79-6.89, p = <.001). The only factors independently associated with high MR was economic dependence and unemployment. Patients with high MR and economic dependence (OR 4.0; 95% CI 1.34-11.99, p = .013) or unemployment (OR 3.43; 95% CI 1.17-10.06, p = .025) had the highest mortality. CONCLUSIONS: In hospitalized older adults with neurological diseases, high MR is independently associated with increased mortality and LOS. Economic dependence or unemployment are associated with worse clinical outcomes in patients with high MR.

RESUMO

BACKGROUND: For patients who are critically ill, the recommended nutrition risk screening tools are the Nutrition Risk in the Critically Ill (NUTRIC) and the Nutritional Risk Screening 2002 (NRS-2002) have limitations. OBJECTIVE: To develop a new screening tool, the Screening of Nutritional Risk in Intensive Care (SCREENIC score), and assess its predictive validity. METHODS: A secondary analysis of a prospective cohort study was conducted. Variables from several nutritional screening and assessment tools were considered. The high nutrition risk cutoff point was defined using mNUTRIC as a reference. Predictive validity was evaluated using logistic regression and Cox regression. RESULTS: The study included 450 patients (64 [54-71] years, 52.2% men). The SCREENIC score comprised six questions: (1) does the patient have ≥2 comorbidities (1.3 points); (2) was the patient hospitalized for ≥2 days before intensive care unit (ICU) admission (0.9 points); (3) does the patient have sepsis (1.0 point); (4) was the patient on mechanical ventilation upon ICU admission (1.2 points); (5) is the patient aged >65 years (1.2 points); and (6) does the patient exhibit signs of moderate/severe muscle mass loss according to the physical exam (0.6 points). The high nutrition risk cutoff point was set at 4.0. SCREENIC demonstrated moderate agreement (κ = 0.564) and high accuracy (0.896 [95% CI, 0.867-0.925]) with mNUTRIC. It predicted prolonged ICU (odds ratio [OR] = 1.81 [95% CI, 1.14-2.85]) and hospital stay (OR = 2.15 [95% CI, 1.37-3.38]). CONCLUSION: The SCREENIC score comprises questions with variables that do not require nutrition history. Further evaluation of its applicability, reproducibility, and validity in guiding nutrition therapy is needed using large external cohorts.

RESUMO

Introduction: The success of diabetes prevention based on early treatment depends on high-quality screening. This study compared the diagnostic properties of currently recommended screening strategies against alternative score-based rules to identify those at high risk of developing diabetes. Methods: The study used data from ELSA-Brasil, a contemporary cohort followed up for a mean (standard deviation) of 7.4 (0.54) years, to develop risk functions with logistic regression to predict incident diabetes based on socioeconomic, lifestyle, clinical, and laboratory variables. We compared the predictive capacity of these functions against traditional pre-diabetes cutoffs of fasting plasma glucose (FPG), 2-h plasma glucose (2hPG), and glycated hemoglobin (HbA1c) alone or combined with recommended screening questionnaires. Results: Presenting FPG > 100 mg/dl predicted 76.6% of future cases of diabetes in the cohort at the cost of labeling 40.6% of the sample as high risk. If FPG testing was performed only in those with a positive American Diabetes Association (ADA) questionnaire, labeling was reduced to 12.2%, but only 33% of future cases were identified. Scores using continuously expressed clinical and laboratory variables produced a better balance between detecting more cases and labeling fewer false positives. They consistently outperformed strategies based on categorical cutoffs. For example, a score composed of both clinical and laboratory data, calibrated to detect a risk of future diabetes ≥20%, predicted 54% of future diabetes cases, labeled only 15.3% as high risk, and, compared to the FPG ≥ 100 mg/dl strategy, nearly doubled the probability of future diabetes among screen positives. Discussion: Currently recommended screening strategies are inferior to alternatives based on continuous clinical and laboratory variables.

RESUMO

OBJECTIVE: To verify the association between nutritional risk on admission and clinical outcomes of COVID-19 in hospitalized children and adolescents. METHODS: Multicenter cohort study was conducted in two cities in the northeastern region of Brazil, with children under 18 years of age laboratory diagnosed with COVID-19. Sociodemographic data and nutritional risk screening by STRONGKids (low, medium and high risk) were collected remotely and in hospital records, respectively. The outcomes assessed were the need for ICU admission, length of stay (< 10 days or ≥ 10 days), critical cases, and death. Multivariable logistic regression models were used to evaluate the effects of high nutritional risk on COVID-19 clinical outcomes. RESULTS: 103 individuals were evaluated, of these 35 (34.0%) had low risk, 44 (42.7%) medium risk, and 24 (23.3%) had high risk of malnutrition. In multivariate analysis, ICU bed admission (OR: 4.57; 95%CI, 1.39-4.97; p = 0.01), hospitalization longer than or equal to ten days (OR: 3.96; 95%CI, 1.22-2.83; p = 0.02) and critical cases (OR: 4.35; 95%CI, 1.08-7.55; p = 0.04) were associated with high nutritional risk. Death was not associated with high nutritional risk. CONCLUSIONS: Children and adolescents with high nutritional risk by STRONGkids at hospital admission were more likely to be admitted to the ICU, have hospitalization longer than or equal to ten days, and have critical cases when infected with SARS-CoV-2.

RESUMO

BACKGROUND: Phase angle (PhA) has been used as mortality prognostic, but there are no studies about its possible use as a screening tool. Therefore, an assessment of the possible utility of PhA in clinical practice is required. The aim of this systematic review was to explore all recent available evidence of PhA, and its possible utility as a screening tool in clinical practice in subjects with chronic metabolic diseases. MATERIALS AND METHODS: This systematic review was performed and written as stated in the PRISMA 2020 guidelines. The search was conducted in PubMed, ScienceDirect and SciElo. In order to be considered eligible, within the entire search, only articles involving PhA and their utility in metabolic diseases were included. RESULTS: PhA was associated with hyperuricemia and vitamin D deficiency in obese subjects, and decreased cardiovascular risk and malnutrition in hospitalized patients. CONCLUSION: PhA may be a potential screening tool in clinical practice to evaluate different biomarkers, cardiovascular risk, and nutritional diagnosis in metabolic diseases in adults.

RESUMO

Alcohol-associated liver disease is one of the main causes of chronic liver disease. It comprises a clinical-histologic spectrum of presentations, from steatosis, steatohepatitis, to different degrees of fibrosis, including cirrhosis and severe necroinflammatory disease, called alcohol-associated hepatitis. In this focused update, we aim to present specific therapeutic interventions and strategies for the management of alcohol-associated liver disease. Current evidence for management in all spectra of manifestations is derived from general chronic liver disease recommendations, but with a higher emphasis on abstinence and nutritional support. Abstinence should comprise the treatment of alcohol use disorder as well as withdrawal syndrome. Nutritional assessment should also consider the presence of sarcopenia and its clinical manifestation, frailty. The degree of compensation of the disease should be evaluated, and complications, actively sought. The most severe acute form of this disease is alcohol-associated hepatitis, which has high mortality and morbidity. Current treatment is based on corticosteroids that act by reducing immune activation and blocking cytotoxicity and inflammation pathways. Other aspects of treatment include preventing and treating hepatorenal syndrome as well as preventing infections although there is no clear evidence as to the benefit of probiotics and antibiotics in prophylaxis. Novel therapies for alcohol-associated hepatitis include metadoxine, interleukin-22 analogs, and interleukin-1-beta antagonists. Finally, granulocyte colony-stimulating factor, microbiota transplantation, and gut-liver axis modulation have shown promising results. We also discuss palliative care in advanced alcohol-associated liver disease.

RESUMO

BACKGROUND: Research using the IPSCAN Child Abuse Screening Tool for Children (ICAST-C), has provided ample evidence of the magnitude of violence against children. Knowledge about its psychometric characteristics and validity is limited. Hence, our objective was to translate and culturally adapt the ICAST-C in adolescents from Mexico City and determine its psychometric properties. PARTICIPANTS AND SETTING: To determine the psychometric properties of the instrument 723 adolescents between 11 and 18 years of age from 9 public secondary schools in Mexico City participated. METHODS: The study was carried out in two phases: 1) translation and adaptation of the instrument (in 5 steps) and 2) pilot evaluation of the psychometric properties. Total and factor reliabilities were determined, Pearson correlation was used for temporal stability while construct validity was determined by Confirmatory Factor Analysis (CFA), and final adequacy of the items eliminated by the CFA. RESULTS: We developed the culturally relevant Mexican Spanish version of the ICAST-C. The CFA confirmed the six-factor structure hypothesis. To improve the original model we eliminated ten items, the final model showed good global fit indices (χ2(1310) = 2207.68, p < .01, χ2/df = 1.68; CFI =0.95; RMSEA = 0.02 [CI95% 0.02-0.03]; SRMR = 0.08). Total and factor reliabilities were adequate (Alpha = 0.79-0.92, r = 0.52-0.75), except for the non-violent discipline factor (Alpha = 0.59, r = 0.38). CONCLUSIONS: While these data suggest that this version of the ICAST-C is valid and reliable for adolescents in Mexico City public secondary schools, further research should evaluate the psychometric properties in a national sample.

RESUMO

OBJECTIVE: To determine the effect of implementation of an automated sepsis screening tool on the median cost of affected patient encounters. STUDY DESIGN: This retrospective cohort study used propensity score-matched comparison groups to assess the difference in median cost for comparable affected patient encounters before and after the implementation of an automated sepsis screening tool in a large US children's hospital emergency department (ED) with >90 000 annual visits. All patient encounters in 2018 impacted by the automated sepsis screening tool were included and compared with a propensity score-matched comparison group drawn from patient encounters in 2012 that might have been affected by the screening tool had it been active at that time. The main outcome was the change in the median cost for comparable affected patient encounters. RESULTS: The overall median cost for those affected by an automated sepsis screening tool decreased by 21.2%, from $6454 (IQR, $968-$21 697) to $5084 (IQR, $802-$16 618). The median cost for encounters with an associated International Classification of Diseases sepsis code decreased by 51.1%, from $58 685 (IQR, $32 224-$134 895) to $28 672 (IQR, $16 796-$60 657). CONCLUSIONS: The median cost for comparable patient encounters decreased with implementation of an automated sepsis screening tool in the pediatric ED. Costs were decreased even more substantially for patients with sepsis. In addition to improving outcomes, an automated sepsis screening tool appears to be at least cost-effective and may be cost-saving, an incentive for more widespread use of this technology.

RESUMO

INTRODUCTION: Representation of Mexican Americans in Alzheimer's disease (AD) clinical research has been extremely poor. METHODS: Data were examined from the ongoing community-based, multi-ethnic Health & Aging Brain among Latino Elders (HABLE) study. Participants underwent functional exams, clinical labs, neuropsychological testing, and 3T magnetic resonance imaging of the brain. Fasting proteomic markers were examined for predicting mild cognitive impairment (MCI) and AD using support vector machine models. RESULTS: Data were examined from n = 1649 participants (Mexican American n = 866; non-Hispanic White n = 783). Proteomic profiles were highly accurate in detecting MCI (area under the curve [AUC] = 0.91) and dementia (AUC = 0.95). The proteomic profiles varied significantly between ethnic groups and disease state. Negative predictive value was excellent for ruling out MCI and dementia across ethnic groups. DISCUSSION: A blood-based screening tool can serve as a method for increasing access to state-of-the-art AD clinical research by bridging between community-based and clinic-based settings.

RESUMO

The use of the dual-task model as a cognitive-motor interface has been extensively investigated in cross-sectional studies as a training task in cognitive impairment. However, few existing longitudinal studies prove the usefulness of this tool as a clinical marker of cognitive impairment in older people. What is the evidence in prospective studies about dual-task gait as a predictor of cognitive impairment in older adults? This study aims to review and discuss the current state of knowledge in prospective studies on the use of dual-task gait as a predictive tool for cognitive impairment in older adults. The methodology used was a systematic review, according to the PRISMA criteria for the search, summarize and report. A search in 3 databases (Pubmed, Web of Science, and Scopus) was carried out until April 2021. The search terms used were: "(gait OR walking) AND (cognitive decline) AND (dual-task) AND (follow-up OR longitudinal OR long-term OR prospective OR cohort OR predict)." We included prospective research articles with older people with cognitive evaluation at the beginning and the end of the follow-up and dual-task gait paradigm as initial evaluation associated with the presentation of cognitive impairment prediction using any dual-task gait parameters. After exclusion criteria, 12 studies were reviewed. The results indicate that eight studies consider dual-task gait parameters a useful cognitive-motor tool, finding that some of the evaluated parameters of dual-task gait significantly correlate with cognitive impairment over time. The most promising DT parameters associated with cognitive impairment prediction seem to be gait speed, speed cost, DT time, numbers of words during DT, among others. In sum, this study reviews the variety of dual-task gait parameters and their relevance as a simple tool for early cognitive impairment screening, opening a diagnostic window for the screening of cognitive impairment in older people.

RESUMO

Abstract Objective: Validate the accuracy of the Screening Tool for Risk on Nutritional status and Growth (STRONGkids) and estimate the prevalence of malnutrition and nutritional risk in hospitalized children. Methods: Cross-sectional study of a representative sample of children admitted to ten public pediatric emergency rooms. The sample was randomly estimated in stages, including children older than 30 days and younger than 10 years of age, of both sexes, excluding syndromic children and those in whom it was impossible to directly measure anthropometry. Weight, height, and arm circumference were measured, as well as the Z-scores of the anthropometric indices weight-for-age, height-for-age, weight-for-height, body mass index for age, and arm circumference for age, classified according to the reference curves of the World Health Organization. After the tool was applied, its accuracy tests were performed in comparison with the anthropometric data, with the evaluation of sensitivity, specificity, and positive and negative predictive values. Results: A total of 271 children were evaluated, 56.46% males and 41.70% younger than 2 years of age. The prevalence rates of malnutrition, nutritional risk assessed by anthropometric measurements, and nutritional risk assessed by the tool were 12.18%, 33.95%, and 78.60%, respectively. Accuracy showed sensitivity of 84.8%, specificity of 26.7%, positive predictive value of 49.8%, and negative predictive value of 67.2%, when the patients at nutritional risk were identified by anthropometry. Conclusion: Validation of the accuracy of STRONGkids was performed, showing high sensitivity, allowing the early identification of nutritional risk in similar populations.

RESUMO

OBJECTIVES: Executive dysfunction is a predominant cognitive symptom in cerebral small vessel disease (SVD). The Institute of Cognitive Neurology Frontal Screening (IFS) is a well-validated screening tool allowing the rapid assessment of multiple components of executive function in Spanish-speaking individuals. In this study, we examined performance on the IFS in subjects with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), an inherited condition leading to the early onset of SVD. We further explored associations between performance on the IFS and magnetic resonance imaging (MRI) markers of SVD. METHODS: We recruited 24 asymptomatic CADASIL subjects and 23 noncarriers from Colombia. All subjects underwent a research MRI and a neuropsychological evaluation, including the IFS. Structural MRI markers of SVD were quantified in each subject, together with an SVD Sum Score representing the overall burden of cerebrovascular alterations. General linear model, correlation, and receiver operating characteristic curve analyses were used to explore group differences on the IFS and relationships with MRI markers of SVD. RESULTS: CADASIL subjects had a significantly reduced performance on the IFS Total Score. Performance on the IFS correlated with all quantified markers of SVD, except for brain atrophy and perivascular spaces enlargement. Finally, while the IFS Total Score was not able to accurately discriminate between carriers and noncarriers, it showed adequate sensitivity and specificity in detecting the presence of multiple MRI markers of SVD. CONCLUSIONS: These results suggest that the IFS may be a useful screening tool to assess executive function and disease severity in the context of SVD.

RESUMO

Matrix-Assisted Laser Desorption Ionization Time-Of-Flight Mass Spectrometry (MALDI-TOF MS) is a rapid, cost-effective and high-throughput method for bacteria characterization. However, most previous studies focused on clinical isolates. In this study, we evaluated the use of MALDI-TOF MS as a rapid screening tool for marine bacterial symbionts. A set of 255 isolates from different marine sources (corals, sponge, fish and seawater) was analyzed using cell lysates to obtain a rapid grouping. Cluster analysis of mass spectra and 16S rRNA showed 18 groups, including Vibrio, Bacillus, Pseudovibrio, Alteromonas and Ruegeria. MALDI-TOF distance similarity scores ≥ 60% and ≥ 70% correspond to ≥ 98.7% 16S rRNA gene sequence similarity and ≥ 95% pyrH gene sequence similarity, respectively. MALDI-TOF MS is a useful tool for Vibrio species groups' identification.

RESUMO

BACKGROUND: The early identification of individuals at high risk for adverse outcomes by a Comprehensive Geriatric Assessment (CGA) in resource-limited primary care settings enables tailored treatments, however, the evidence concerning its benefits are still controversial. The main objective of this study was to examine the validity and reliability of the "Multidimensional Assessment of Older People in Primary Care (AMPI-AB)", a CGA for primary care in resource-limited settings. METHODS: Longitudinal study, with median follow-up time of 16 months. Older adults from a public primary care unit in São Paulo, Brazil, were consecutively admitted. Reliability was tested in a sample from a public geriatric outpatient clinic. Participants were classified by the AMPI-AB score as requiring a low, intermediate or high complexity of care. The Physical Frailty Phenotype was used to explore the AMPI-AB's concurrent validity. Predictive validity was assessed with mortality, worsening of the functional status, hospitalizations, emergency room (ER) visits and falls. The area under the ROC curve and logistic regression were calculated for binary outcomes, and a Cox proportional hazards model was used for survival analysis. RESULTS: Older adults (n = 317) with a median age of 80 (74-86) years, 67% female, were consecutively admitted. At the follow-up, 7.1% of participants had died, and increased dependency on basic and instrumental activities of daily living was detected in 8.9 and 41.1% of the participants, respectively. The AMPI-AB score was accurate in detecting frailty (area under the ROC curve = 0.851), predicted mortality (HR = 1.25, 95%CI = 1.13-1.39) and increased dependency on basic (OR = 1.26, 95%CI = 1.10-1.46) and instrumental (OR = 1.22, 95%CI = 1.12-1.34) activities of daily living, hospitalizations (OR = 2.05, 95%CI = 1.04-1.26), ER visits (OR = 1.20, 95%CI = 1.10-1.31) and falls (OR = 1.10, 95%CI = 1.01-1.20), all models adjusted for sex and years of schooling. Reliability was tested in a sample of 52 older adults with a median age of 72 (85-64) years, 63.5% female. The AMPI-AB also had good interrater (ICC = 0.87, 95%CI = 0.78-0.92), test-retest (ICC = 0.86, 95%CI = 0.76-0.93) and proxy reliability (ICC = 0.84, 95%CI = 0.67-0.93). The Cronbach's alpha was 0.69, and the mean AMPI-AB administration time was 05:44 ± 02:42 min. CONCLUSION: The AMPI-AB is a valid and reliable tool for managing older adults in resource-limited primary care settings.

RESUMO

BACKGROUND: The Zanmi Lasante Depression Symptom Inventory (ZLDSI) is a screening tool for major depression used in 12 primary care clinics in Haiti's Central Plateau. Although previously validated in a clinic-based sample, the present study is the first to evaluate the validity and clinical utility of the ZLDSI for depression screening in a school-based population in central Haiti. METHODS: We assessed depressive symptoms in a school-based sample of transitional age youth (18-22 years; n = 120) with the ZLDSI. Other mental health-related assessments included a modified Structured Clinical Interview for DSM-IV-TR Axis I Disorders (SCID) for current Major Depressive Episode, the Center for Epidemiologic Studies Depression Scale, and selected items adapted from the Global School-Based Health Survey mental health module. Diagnostic assignments of major depressive episode (MDE) were based on modified SCID interviews. RESULTS: The ZLDSI demonstrated good overall accuracy in identifying current MDE (Area under the Curve = .92, 95% CI = .86, .98, p < .001). We ascertained ≥12 as the optimal cut-off point to screen for depression with a sensitivity of 100% and a specificity of 73.9%. In addition, the ZLDSI was associated with other measures of depressive symptoms, suggesting that it demonstrates construct validity. CONCLUSIONS: Study findings support that the ZLDSI has clinical utility for screening for depression among school-going transitional age youth.

RESUMO

OBJECTIVE: Validate the accuracy of the Screening Tool for Risk on Nutritional status and Growth (STRONGkids) and estimate the prevalence of malnutrition and nutritional risk in hospitalized children. METHODS: Cross-sectional study of a representative sample of children admitted to ten public pediatric emergency rooms. The sample was randomly estimated in stages, including children older than 30 days and younger than 10 years of age, of both sexes, excluding syndromic children and those in whom it was impossible to directly measure anthropometry. Weight, height, and arm circumference were measured, as well as the Z-scores of the anthropometric indices weight-for-age, height-for-age, weight-for-height, body mass index for age, and arm circumference for age, classified according to the reference curves of the World Health Organization. After the tool was applied, its accuracy tests were performed in comparison with the anthropometric data, with the evaluation of sensitivity, specificity, and positive and negative predictive values. RESULTS: A total of 271 children were evaluated, 56.46% males and 41.70% younger than 2 years of age. The prevalence rates of malnutrition, nutritional risk assessed by anthropometric measurements, and nutritional risk assessed by the tool were 12.18%, 33.95%, and 78.60%, respectively. Accuracy showed sensitivity of 84.8%, specificity of 26.7%, positive predictive value of 49.8%, and negative predictive value of 67.2%, when the patients at nutritional risk were identified by anthropometry. CONCLUSION: Validation of the accuracy of STRONGkids was performed, showing high sensitivity, allowing the early identification of nutritional risk in similar populations.

RESUMO

Abstract Background: The general development assessment test (EVADE) for children and adolescents aged 6-14 years is the only national screening tool for development assessment of school-age children and adolescents. This article presents the results obtained after applying the face validity process to the test, the handbook, and the standardized materials. Methods: An exploratory, descriptive study was conducted with a quantitative-qualitative methodology. The EVADE test was applied to a sample of 730 children and adolescents between 6 and 14 years of age, for which the expert judgment technique was used. Data analysis was carried out through a psychometric analysis of the items and by the triangulation method. Results: From the 730 participants included, 44.5% were from rural areas (n = 325) and 55.4% from urban areas (n = 405), of which 51.7% (n = 378) of females and 48.2% (n = 352) of males were assessed by the test. The difficulty level and discriminative effectiveness quotient of the items were calculated, which, together with the experts' findings, resulted in 22-item modifications and the creation of four new items in the cognitive and language areas. The qualification by areas also changed, improving the handbook and creating new materials. Conclusions: This research provides a validated screening test for the child and adolescent population, which was included in the Costa Rican comprehensive childcare public policy. However, subsequent validation processes are recommended to improve specific areas, such as motor skills and social-affective development.


Resumen Introducción: La prueba general para la evaluación del desarrollo (EVADE) para niñas, niños y adolescentes entre 6 y 14 años es la única prueba a nivel nacional que valora el desarrollo en población escolar y adolescente. Este artículo presenta los resultados tras someter la prueba, el instructivo y los materiales estandarizados al proceso de validación de apariencia. Métodos: Se llevó a cabo un estudio descriptivo exploratorio, con metodología cuantitativa-cualitativa. La prueba EVADE se aplicó a una muestra de 730 niñas, niños y adolescentes entre 6 y 14 años; asimismo, se utilizó la técnica de juicio de expertos. El análisis de los datos se efectuó a través de un análisis psicométrico de los enunciados y triangulación. Resultados: De los 730 participantes, el 44.5% correspondió a zonas rurales (n = 325) y el 55.4% a zonas urbanas (n = 405). El 51.7% de ellos eran de sexo femenino (n = 378) y el 48.2%, de sexo masculino (n = 352). Se calculó el nivel de dificultad y el coeficiente de efectividad discriminativa para los enunciados. A la par de los hallazgos referidos por los expertos, resultó en la modificación de 22 enunciados, la creación de cuatro nuevos artículos en las áreas cognitiva y de lenguaje. También se cambió la calificación por áreas, se mejoró el instructivo y se crearon nuevos materiales. Conclusiones: La presente investigación aporta una prueba validada para la población infantil escolar y adolescente, que fue incluida en la política pública de atención integral de la población infantil costarricense. Se recomiendan procesos de validación subsecuentes con el fin de mejorar áreas específicas, como motricidad y socioafectiva.
