“…Because of the reduced sensibility of the Denver I test for language development, a more complete test was developed, Denver II [16]. The Denver II test has improved sensibility for the detection of deficits in the area of language (>85%) [17]. We started our study in 1995, using the Denver I test, and from 1999 on we also began to use Denver II.…”

“…The Denver II test increases coverage of language, allowing for greater fidelity/credibility in this area [16,17]. This test began being applied in the outpatient clinic of the neuropediatric unit of HC-UFPR at the end of 1999.…”

“…The so-called Denver I test [15] was initially known as the DDST (Denver Developmental Screen Test), and a more complete version, Denver II test [16,17], was derived from it. It consists of an evaluation of various areas of neurodevelopment, language, personal-social, adaptive and fine and gross motor, varying the aptitude requirements in accordance with age; it can be applied from 0 to 6 years of age.Children can pass or fail the Denver test.…”

This study evaluated the degree of neurological compromise in HIV-infected children accompanied by the outpatient clinic of infectious diseases and pediatric neurology of the Clinical Hospital of the Federal University of Paraná (UFPR) starting in 1995. Long-term progressive prospective and cross sectional study of 88 children infected by HIV and 84 seroreverter children, using data from general neurological examinations, neuroimaging procedures (brain CT scan) and neurodevelopmental tests (CAT/CLAMS and DENVER I and II). Neurological and neurodevelopmental alterations were found in 82% of the HIV-infected patients and in 36% of the HIV-seroreverter group (P <0.01). In the CAT/ CLAMS test, the development quotient (DQ) of the HIV-infected group was significantly lower than that of the HIV-seroreverter group. CAT/CLAMS scores lower than 70 (mental deficiency) were found in 31% of the HIV-infected patients during the first year of life and in only 1% of the patients of the HIV-seroreverter group, demonstrating the validity of this screening test for precocious detection of alterations in the neurodevelopment of infected patients. The same occurred with the Denver I and II tests, as the HIV-infected group failed more frequently than the HIV-seroreverter group. Nine HIVinfected children presented altered brain CT scans; calcification of basal ganglia was the main finding (five cases). Encephalopathy due to HIV causes early arrest of neurodevelopment, which can be detected with screening tests during the first year of life.

“…It can also enable healthcare providers to isolate specific problem areas, enabling interventions to be individually tailored to children. Although DDST-II is reported to have excellent sensitivity (low false negative rate) (83%), its low specificity (high false positive rate), has been questioned (Glascoe et al 1992;Glascoe 2002). On the other hand, other research has indicated that the high false positive rate can be reduced by means of clinical judgement and repeat screening and that it is a useful tool to identify children who are developmentally delayed, who would otherwise be missed (Lim et al 1996).…”

AbstractBackground Developmental problems in children can be alleviated to a great extent with early detection and intervention through periodic screening for developmental delays during pre-school ages. Currently, there is no established system for developmental screening of children in Sri Lanka. Although some developmental norms, which are similar to those of Denver Developmental Screening Test-II (DDST-II), have been introduced into the Sri Lankan Child Health Developmental Record (CHDR), those norms have not been standardized to the Sri Lankan child population. The aim of this research was to establish Sri Lankan norms for DDST-II and to test the universal and regional applicability of developmental screening tests by comparing the Sri Lankan norms with the norms of DDST-II and DDST-Singapore norms, the geographically nearest standardization of DDST-II. The norms were also compared with the milestones already available in the CHDR. Methods DDST-II was adapted and standardized on a sample of 4251 Sri Lankan children aged 0-80 months. Thirteen public health nursing sisters were trained to collect the data as part of their routine work. The 25th, 50th, 75th and 90th percentile ages of acquiring each developmental milestone were then calculated using logistic regression. Results The Denver Developmental Screening Test for Sri Lankan Children (DDST-SL) was created. Most of the established DDST-SL norms were different to the comparable norms in DDST-II, DDST-Singapore and the CHDR. Conclusions In view of the results of the study, it is imperative that developmental screening tests are used in context and are adapted and standardized to the populations in question before utilization.

“…The BDT correctly classified 94% of the participants, an excellent hit rate. It also had an excellent sensitivity rate, correctly classifying 96.4% of the dyslexic group, well above the minimum recommended, 80% (Glascoe & Byrne, 1993). This high sensitivity rate ensures that the number of false negatives is kept to a minimum and that most adults who are at risk of dyslexia will be correctly identified.…”

The Bangor Dyslexia Test (BDT) is a short, easy-to-administer screener for use with a broad age range, which has been in use in the United Kingdom for over three decades. A distinctive feature of the battery is its focus on skills requiring aspects of verbal and phonological processing without, however, measuring literacy skills per se. Despite its longstanding existence and usage, there has been no evaluation of the psychometric properties of the battery as an adult dyslexia screener. We examined the psychometric properties of the BDT and evaluated its capacity to discriminate between adults with and without dyslexia. A large archival sample of university students with dyslexia (n = 193) and students with no reported literacy difficulties (n = 40) were compared on the BDT as well as on literacy and cognitive measures. Statistical analyses revealed the BDT to be a reliable (α = .72) and valid dyslexia screening tool with the capacity to effectively identify adults at risk of the disorder with an overall classification rate of 94% (sensitivity 96.4% and specificity 82.5%). In addition, higher indices of dyslexia risk on the BDT were associated with lower scores on standardized measures of literacy.Keywords: dyslexia; adults; screening test; higher education; Bangor Dyslexia Test; evaluation Practitioner Points: The BDT can be used by practitioners to effectively screen for dyslexia in adults  Knowledge of the psychometric properties of screening tests is useful for the selection of the most appropriate tools  Independent research is one method of confirming/validating the effectiveness of screening tests  Continuing independent research ensures that screening tests remain appropriate in light of our increased knowledge and understanding of dyslexia
