Review of diagnostic screening instruments for alcohol and other drug use and other psychiatric disorders

In recent years there has been a growing recognition that many people with drug or alcohol problems are also experiencing a range of other psychiatric and psychological problems. The presence of concurrent psychiatric or psychological problems is likely to impact on the success of treatment services. These problems vary greatly, from undetected major psychiatric illnesses that meet internationally accepted diagnostic criteria such as those outlined in the Diagnostic and Statistical Manual (DSM-IV) of the American Psychiatric Association (1994), to less defined feelings of low mood and anxiety that do not meet diagnostic criteria but nevertheless impact on an individual’s sense of wellbeing and affect their quality of life.

Efficacy of three screening instruments in the identification of autistic-spectrum disorders

Background Screening instruments for autistic-spectrum disorders have not been compared in the same sample. Aims To compare the Social Communication Questionnaire (SCQ), the Social Responsiveness Scale (SRS) and the Children's Communication Checklist (CCC). Method Screen and diagnostic assessments on 119 children between 9 and 13 years of age with special educational needs with and without autistic-spectrum disorders were weighted to estimate screen characteristics for a realistic target population. Results The SCQ performed best (area under receiver operating characteristic curve (AUC)=0.90; sensitivity. 6; specificity 0.78). The SRS had a lower AUC (0.77) with high sensitivity (0.78) and moderate specificity (0.67). The CCC had a high sensitivity but lower specificity (AUC=0.79; sensitivity 0.93; specificity 0.46). The AUC of the SRS and CCC was lower for children with IQ < 70. Behaviour problems reduced specificity for all three instruments. Conclusions The SCQ, SRS and CCC showed strong to moderate ability to identify autistic-spectrum disorder in this at-risk sample of school-age children with special educational needs.

Validity of alcohol screening instruments in general population gender studies: an analytical review

The present study is an analytical review of the methodology used in studies of efficacy of screening instruments to detect harmful use/ alcohol dependence according to the gender in population surveys. Systematic review of bibliography was done, using data from Web of Science, Pubmed and PsycInfo. Population studies were included without date range, in English, Spanish or Portuguese languages, with sample of adults, evaluating psychometric characteristics of any alcohol screening instrument, whereas studies in special population or under treatment as well as prevalence of alcohol consumption were excluded. Thirteen studies were selected to be included in the present review. According to the studies, the instruments that presented a better performance among men were AUDIT and its derivatives (6 studies) and CAGE (2 studies), whereas among women, AUDIT and its derivatives (7 studies), followed by CAGE (3 studies). The increase of consumption and problems related to alcohol use and its implications for public health indicate the need and urgency for adequacy of screening instruments to differences of gender in general population. The population surveys in the area are scarce. Furthermore, the found studies present heterogeneous methodology which makes accurate comparisons difficult.

Identification of prognostic factors for chronicity in patients with low back pain: a review of screening instruments

Low back pain (LBP) is currently the most prevalent and costly musculoskeletal problem in modern societies. Screening instruments for the identification of prognostic factors in LBP may help to identify patients with an unfavourable outcome. In this systematic review screening instruments published between 1970 and 2007 were identified by a literature search. Nine different instruments were analysed and their different items grouped into ten structures. Finally, the predictive effectiveness of these structures was examined for the dependent variables including "work status", "functional limitation", and "pain". The strongest predictors for "work status" were psychosocial and occupational structures, whereas for "functional limitation" and "pain" psychological structures were dominating. Psychological and occupational factors show a high reliability for the prognosis of patients with LBP. Screening instruments for the identification of prognostic factors in patients with LBP should include these factors as a minimum core set.

Entwicklung eines Screening-Instruments zu Rumination und Suppression RS-8

Rumination und Suppression sind 2 maladaptive Emotionsregulationsstrategien, die im Zusammenhang mit pathologischem Verhalten wie übermäßigem Essen oder Trinken stehen. Ein Messinstrument, welches beide Strategien in Kurzform erfasst, fehlt bisher. Der RS-8 erfasst mit 8 Items die beiden Dimensionen Rumination und Suppression. Anhand von 2 klinischen (Patienten mit Alkoholabhängigkeit [n = 79], Patienten mit Adipositas [n = 53]) und einer nichtklinischen Stichprobe (n = 133) wurde die psychometrische Qualität der Skala überprüft. Die Ergebnisse zeigen, dass der RS-8 ein valides und reliables Messinstrument ist. Die interne Konsistenz kann als gut und die faktorielle Validität als sehr gut bewertet werden. Der RS-8 ist ein ökonomisches Screening-Instrument, welches bei klinischen und nicht-klinischen Stichproben eingesetzt werden kann.

Screening for Alzheimer`s Disease Among Illiterate Elderly: Accuracy Analysis for Multiple Instruments

One of the challenges in screening for dementia in developing countries is related to performance differences due to educational and cultural factors. This study evaluated the accuracy of single screening tests as well as combined protocols including the Mini-Mental State Examination (MMSE), Verbal Fluency animal category (VF), Clock Drawing test (CDT), and Pfeffer Functional Activities Questionnaire (PFAQ) to discriminate illiterate elderly with and without Alzheimer`s disease (AD) in a clinical sample. Cross-sectional study with 66 illiterate outpatients diagnosed with mild and moderate AD and 40 illiterate normal controls. Diagnosis of AD was based on NINCDS-ADRDA. All patients were submitted to a diagnostic protocol including a clinical interview based on the CAMDEX sections. ROC curves area analyses were carried out to compare sensitivity and specificity for the cognitive tests to differentiate the two groups (each test separately and in two by two combinations). Scores for all cognitive (MMSE, CDT, VF) and functional assessments (PFAQ) were significantly different between the two groups (p < 0.001). The best screening instruments for this sample of illiterate elderly were the MMSE and the PFAQ. The cut-off scores for the MMSE, VF, CDT, and PFAQ were 17.5, 7.5, 2.5, and 11.5, respectively. The most sensitive combination came from the MMSE and PFAQ (94.1%), and the best specificity was observed with the combination of the MMSE and CDT (89%). Illiterate patients can be successfully screened for AD using well-known screening instruments, especially in combined protocols.

Effectiveness of screening for risk of medical emergencies in the elderly

Study objective: UK government policy mandates the introduction of 'intermediate care services' to reduce emergency admissions to hospital from the population aged 75 years or more. We evaluated one of these initiatives-the Keep Well At Home (KWAH) Project-in a West London Primary Care Trust. Design: KWAH involves a two-phase screening process, including a home visit by a community nurse. We employed cohort methods to determine whether KWAH resulted in fewer emergency attendances and admissions to hospital in the target population, from October 1999 to December 2002. Results: estimated levels of coverage in the two phases of screening were 61 and 32%, respectively. The project had not maintained records of which additional health and social care services had been delivered following screening. The rates of emergency admissions to hospital in the 9 months before screening were similar in practices that did and did not join the project (rate ratio (RR) = 1.05; 95% CI 0.95-1.17), suggesting absence of volunteer bias. Over the first 37 months of the project, there was no significant impact on either attendances at Accident & Emergency departments (RR = 1.02; 95% CI 0.97-1.06) or emergency admissions of elderly patients (RR = 0.98; 95% CI 0.93-1.05). Conclusion: the KWAH Project has been ineffective in reducing emergency admissions among the elderly. Significant questions arise in relation to selection of the screening instruments, practicality of achieving higher coverage of the eligible population, and creation of a new postcode lottery.

Validity of the self reporting questionnaire-20 in epidemiological studies with older adults

This study examined the validity of the self-reporting questionnaire (SRQ-20) in a population-based survey with older adults in Sao Paulo, Brazil. The study sample consisted of 2,008 individuals aged 65 years or more who were living in an economically disadvantaged area of the city. The geriatric mental state (GMS) was used as the gold standard for the assessment of common mental disorders (CMD). The optimal SRQ-20 threshold for case definition was 4/5 (sensitivity = 76.1%, specificity = 74.6%, area under ROC curve = 0.82). Women, older participants and those with lower income were more likely to be misclassified by the questionnaire. The inclusion of older persons with dementia or psychosis did not change the ability of the SRQ-20 to identify cases of CMD. The SRQ-20 may be a useful instrument to be used in large epidemiological studies in resource-poor settings for the identification of cases of depression and anxiety in later life. The performance of the SRQ-20 among older adults was similar to that observed with the adult population in Brazil.

The validity of an Australian modification of the AUDIT questionnaire

The Alcohol Use Disorders Identification Test (AUDIT) has been used widely and is reported to be superior to conventional questionnaires in detection of current hazardous and harmful alcohol use. We assessed the validity of an Australian modification of the AUDIT (the AusAUDIT), which has been employed widely in Australian and New Zealand early intervention programmes. We used a cross-sectional study of 370 subjects from the follow-up phase of a randomized controlled trial of early intervention to reduce hazardous alcohol consumption. Scores on the AusAUDIT were compared against 12-month ICD-10 diagnoses of harmful alcohol use and dependence, as determined by the Composite International Diagnostic Interview, and against self-report of alcohol consumption exceeding Australian National Health and Medical Research Council (NH&MRC) recommended limits. AusAUDIT had good internal consistency and discriminated significantly between persons meeting criteria for ICD-10 alcohol use disorders, and drinkers who did not. At currently recommended cut-off scores, AusAUDIT detected more than 85% of people meeting criteria for ICD-10 alcohol use disorders, or drinking over NH&MRC recommended limits, but its specificity was limited (29% in men, and 58% in women for drinking over NH&MRC limits). No subset of questions performed as well as the full AusAUDIT in detection of drinking problems, but the alcohol consumption items provided a reasonable screen for drinking over NH&MRC limits. We conclude that AusAUDIT is effective in detecting problematic drinking, but positive cases should be confirmed by clinical assessment. The findings illustrate the need for validation of questionnaire modifications, and the difficulty in increasing test sensitivity without reducing specificity.

Perturbações da deglutição : contribuição para a validação do P-EAT-10 numa população institucionalizada e utentes de Centro de Dia

RESUMO: O acelerado processo de envelhecimento da população portuguesa apresentando taxa negativa de crescimento (OCDE, 2013) corrobora para o surgimento de doença crónicas e incapacitantes que, por conseguinte, pode levar os idosos a apresentar dificuldades na deglutição. Alguns instrumentos de despiste das dificuldades de deglutição estão surgindo ao longo dos últimos anos facilitando o rastreio rápido dessas dificuldades. Objectivo: Este trabalho teve como objectivos de estudo caracterizar uma população de idosos institucionalizados e utentes de centro de dia quantos aos seus dados sócio demográficos, deglutição e a linguagem, bem como contribuir para a validação da versão portuguesa do P-EAT-10. Métodos: Realizou-se um estudo do tipo descritivo, transversal, analítico-correlacional com abordagem quantitativa, onde foi feito um levantamento dos dados sociodemográficos e das condições de saúde de 30 idosos institucionalizados e utentes de centro de dia, de ambos os sexos e com idades acima dos 64 anos. Foram aplicados instrumentos para verificar a percepção do estado de saúde (EQ-5D), o estado cognitivo (MMSE), o estado de depressão (EDP), o grau de dependência (IB), a deglutição (P-EAT-10 e 3OZ Wst), a linguagem (TN e TT). Algumas hipóteses foram levantadas e para estudálas utilizamos testes não-paramétricos (U de Mann Whitney, Kruskal-Wallis e Correlação de Spearman, p<0,05). Resultados: Observou-se que os idosos do sexo feminino é maioria (72,7%) na população estudada. Os idosos com mais de 84 anos apresentaram maior percentagem de deficit cognitivo e sinais depressivos. Quanto a deglutição a maioria dos idosos tem percepção das dificuldades de deglutição. Verificou-se haver relação significativa entre o score do P-EAT-10 e o score do 3OZwst (p= 0,016), assim como também entre as habilitações literárias, as morbilidades e a linguagem (nomeação, p<0,047). Conclusão: Nosso estudo levou-nos a concluir a necessidade de testes de rastreio para as dificuldades da deglutição para a população em estudo, sendo o P-EAT-10 um bom instrumento e que associado a outros instrumentos de avaliação podem ajudar na prevenção das dificuldades de deglutição/ disfagia.---------------ABSTRACT:The accelerated aging of the Portuguese population showed a negative growth rate (OECD, 2013) corroborates the emergence of chronic and disabling diseases. Therefore, can lead seniors have difficulty in swallowing. Some screening instruments of swallowing difficulties are emerging over the last few years facilitating rapid screening of these difficulties. Methods: We conducted a descriptive study, crosssectional,correlational with quantitative analytical approach, where a survey was made of sociodemographic and health status of 30 institutionalized elderly and users of the day center, of both sexes and ages above 64 years. Instruments were applied to verify the perception of health status (EQ-5D), cognitive status (MMSE), the severity of depression (EDP), the degree of dependence (IB), swallowing (P-EAT-10:03 OZ Wst), and language (TN and TT). Some hypotheses were to study them and used nonparametric tests (Mann-Whitney U, Kruskal-Wallis and Spearman correlation, p <0.05). Results: It was observed that the elderly female is majority (72.7%) in the study population. Elderly patients over 84 years were mainly cognitive deficits and depressive signs. As for swallowing most seniors have perceptions of swallowing difficulties. Found to be no significant relationship between the score of the P-EAT-10 score and the 3OZwst (p = 0.016), as well as between educational attainment, the morbidities and language (naming, p <0.047). Conclusion: Our study led us to conclude the need for screening tests for swallowing difficulties for the population being studied, and the PEAT-10 a good instrument and associated with other assessment tools can help to prevent difficulties swallowing / dysphagia.

Calibration of surface contamination monitors for the detection of iodine incorporation in the thyroid gland.

In Switzerland, individuals exposed to the risk of activity intake are required to perform regular monitoring. Monitoring consists in a screening measurement and is meant to be performed using commonly available laboratory instruments. More particularly, iodine intake is measured using a surface contamination monitor. The goal of the present paper is to report the calibration method developed for thyroid screening instruments. It consists of measuring the instrument response to a known activity located in the thyroid gland of a standard neck phantom. One issue of this procedure remains that the iodine radioisotopes have a short half-life. Therefore, the adequacy and limitations to simulate the short-lived radionuclides with so-called mock radionuclides of longer half-life were also evaluated. In light of the results, it has been decided to use only the appropriate iodine sources to perform the calibration.
