Selected AbstractsLong-Term Effectiveness of Screening for Hearing Loss: The Screening for Auditory Impairment,Which Hearing Assessment Test (SAI-WHAT) Randomized TrialJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 3 2010Bevan Yueh MD OBJECTIVES: To evaluate the effect of hearing screening on long-term hearing outcomes in a general population of older veterans. DESIGN: Hearing loss in the elderly is underdetected and undertreated. Routine hearing screening has been proposed, but it is not clear whether screening identifies patients who are sufficiently motivated to adhere to treatment. A four-arm randomized clinical trial was conducted to compare three screening strategies with no screening in 2,305 older veterans seeking general medical care. SETTING: Veterans Affairs Puget Sound Health Care System. INTERVENTIONS: The screening strategies were a tone-emitting otoscope, a widely used questionnaire about hearing handicap, and a combination of both tools. MEASUREMENTS: Hearing aid use 1 year after screening. RESULTS: Of participants who underwent screening with the tone-emitting otoscope, questionnaire, and combined testing, 18.6%, 59.2%, and 63.6%, respectively, screened positive for hearing loss (P<.01 for test of equality across three arms). Patients proceeded to formal audiology evaluation 14.7%, 23.0%, and 26.6% of the time in the same screening arms, compared with 10.8% in the control arm (P<.01 for test of equality across four arms). Hearing aid use 1 year after screening was 6.3%, 4.1%, and 7.4% in the same arms, compared with 3.3% in the control arm (P<.01). Hearing aid users experienced significant improvements in hearing-related function and communication ability. CONCLUSION: In older veterans, screening for hearing loss led to significantly more hearing aid use. Screening with the tone-emitting otoscope was more efficient. The results are most applicable to older populations with few cost barriers to hearing aids. [source] A SIBTEST Approach to Testing DIF Hypotheses Using Experimentally Designed Test ItemsJOURNAL OF EDUCATIONAL MEASUREMENT, Issue 4 2000Daniel M. Bolt This paper considers a modification of the DIF procedure SIBTEST for investigating the causes of differential item functioning (DIF). One way in which factors believed to be responsible for DIF can be investigated is by systematically manipulating them across multiple versions of an item using a randomized DIF study (Schmitt, Holland, & Dorans, 1993). In this paper: it is shown that the additivity of the index used for testing DIF in SIBTEST motivates a new extension of the method for statistically testing the effects of DIF factors. Because an important consideration is whether or not a studied DIF factor is consistent in its effects across items, a methodology for testing item x factor interactions is also presented. Using data from the mathematical sections of the Scholastic Assessment Test (SAT), the effects of two potential DIF factors,item format (multiple-choice versus open-ended) and problem type (abstract versus concrete),are investigated for gender Results suggest a small but statistically significant and consistent effect of item format (favoring males for multiple-choice items) across items, and a larger but less consistent effect due to problem type. [source] Progress in International Reading Literacy Study 2006 (PIRLS): pedagogical correlates of fourth-grade students in Hong KongJOURNAL OF RESEARCH IN READING, Issue 3 2009Wai Ming Cheung Reading literacy of fourth-grade students in Hong Kong showed a remarkable improvement from 2001 to 2006 as shown by international PIRLS studies. This study identified various aspects of the teacher factor contributing to the significant improvement among students. A total of 4,712 students and 144 teachers from 144 schools were randomly selected using probability proportional-to-size technique to receive the Reading Assessment Test and complete the Teacher's Questionnaire, respectively. A number of items pertaining to teachers' instructional strategies and activities, opportunities for students to read various types of materials, practices on assessment, and professional preparation and perception, were found to be significantly correlated with the outcome of students' reading literacy. Stepwise regression procedure revealed four significant predictors for students' overall reading achievement. The most powerful predictor was the use of materials from other subjects as reading resources. Suggestions to improve quality of teaching of reading and further studies are made. [source] Pretreatment assessment and predictors of hepatitis C virus treatment in US veterans coinfected with HIV and hepatitis C virusJOURNAL OF VIRAL HEPATITIS, Issue 12 2006L. I. Backus Summary., The US Department of Veterans Affairs (VA) cares for many human immunodeficiency virus/hepatitis C virus (HIV/HCV)-coinfected patients. VA treatment recommendations indicate that all HIV/HCV-coinfected patients undergo evaluation for HCV treatment and list pretreatment assessment tests. We compared clinical practice with these recommendations. We identified 377 HIV/HCV-coinfected veterans who began HCV therapy with pegylated interferon and ribavirin and 4135 HIV/HCV-coinfected veterans who did not but were in VA care at the same facilities during the same period. We compared laboratory and clinical characteristics of the two groups and estimated multivariate logistic regression models of receipt of HCV treatment. Overall, patients had high rates of receipt of tests necessary for HCV pretreatment assessment. Patients starting HCV treatment had higher alanine aminotransferase (ALT), lower creatinine, higher CD4 counts and lower HIV viral loads than patients not starting HCV treatment. In the multivariate model, positive predictors of starting HCV treatment included being non-Hispanic whites, having higher ALTs, lower creatinines, higher HCV viral loads, higher CD4 counts, undetectable HIV viral loads and receiving HIV antiretrovirals. A history of chronic mental illness and a history of hard drug use were negative predictors. Most HIV/HCV-coinfected patients received the necessary HCV pretreatment assessments, although rates of screening for hepatitis A and B immunity can be improved. Having well-controlled HIV disease is by far the most important modifiable factor affecting the receipt of HCV treatment. More research is needed to determine if the observed racial differences in starting HCV treatment reflect biological differences, provider behaviour or patient preference. [source] Reflections on six years of the National Literacy Strategy in England: an interview with Stephen Anwyll, Director of the NLS 2001,2004LITERACY, Issue 3 2004Kathy Hall Abstract This recorded interview with Stephen Anwyll took place in Summer 2004, just prior to his departure from the post of Director of the National Literacy Strategy to take up a new post. In the interview, Stephen challenges those critics who characterise the Strategy as reductive and mechanistic, but recognises the potential for it to be interpreted in this way if not mediated through knowledgeable and confident teachers. He reflects on how the Strategy has changed and developed over time, and talks about new developments, including greater emphasis on the enjoyment of reading, the importance of encouraging speaking and listening and the recognition of the multiple literacies that children encounter and use. This interview is significant in that it places on public record, for the first time, the detailed views of policy makers at the centre of the NLS concerning the successes and challenges around the implementation and development of the Strategy during the last six years. It was recorded before the results of the 2004 standard assessment tests were known. The transcript below has not been edited into a formal written account. It retains the form of spoken discourse. [source] The frequency of absence of palmaris longus in a South African population of mixed raceCLINICAL ANATOMY, Issue 4 2010Robert Ndou Abstract The palmaris longus (PL) is a weak flexor of the wrist that may be harvested as a tendon graft and used in surgical procedures for reconstructive purposes. The PL is congenitally absent in 15% of the worldwide population. However, the frequency of absence varies considerably among different population groups, being as high as 63.9% in the Turkish population and as low as 3% in the black population in the Republic of Congo. In this study, South African persons of mixed race (n = 201) were assessed by two anatomists for the presence of the PL tendon using three clinical tests, namely the Traditional Test, Mishra's Test II, and the Gangata Test. The most reliable of the three tests used was determined using Kendall's coefficient of concordance. Of the total number of subjects used, 11.5% had absence (either bilaterally or unilaterally) of the PL tendon. There was a 5.5% bilateral absence of the PL. The study revealed that the PL tendon may present in six different patterns according to the clinical assessment tests applied, the presence or absence of the PL alongside the flexor capi radialis, and the degree of prominence of PL, if present. Using the Kendall's coefficient of concordance, the Mishra's Test II, and the Gangata Test, both involving abduction of the thumb, were found to be most effective in revealing the PL. The frequency of absence of the PL in South Africans of mixed race has been determined. Clin. Anat. 23:437,442, 2010. © 2010 Wiley-Liss, Inc. [source] | |||||||||||||
