Validity of self-reported reading disability by parents of reading-disabled and control children

Composite reading scores obtained from parents of 125 reading-disabled children and 125 matched control children who participated in the Colorado Family Reading Study were used to test the validity of self-reported reading problems. Parents who reported that they encountered serious difficulty learning to read had significantly lower reading scores than did those who reported no positive history of reading problems. Moreover, this difference was larger for parents of reading-disabled children than for those of controls. Thus, parental self-reports provide a valid index of reading problems.     

Gender differences in cognitive abilities of reading-disabled twins

Gender differences were assessed in three research-identified samples of children who were members of twin pairs: (1) 120 male and 124 female probands from same-sex identical and fraternal twin pairs in which at least one member of each pair is reading disabled; (2) a comparison sample of 148 males and 161 females from same-sex twin pairs with no history of reading problems; and (3) 34 pairs of opposite-sex fraternal twin pairs in which at least one member of each pair is reading disabled. Results of multivariate analyses of variance of psychometric test data from the two samples of same-sex twin pairs, in which the male and female subjects were reared in different homes, suggest that profiles of gender differences are similar in reading-disabled and control children. Moreover, this pattern of gender differences also tended to occur in opposite-sex twin pairs, who shared prenatal, as well as early postnatal, environmental influences. In general, reading-disabled males obtained higher average scores than affected females on Wechsler (1974, 1981) Verbal and Performance IQ, but lower scores on Reading Recognition and Spelling subtests of the Peabody Individual Achievement Test (Dunn and Markwardt 1970). With regard to the Wechsler subtests, reading-disabled males achieved higher average scores on Information, Picture Completion, Block Design, and Object Assembly, but lower scores on Coding. Although significant and relatively consistent gender differences in cognitive measures were found in three samples included in this study, these differences account for only a small portion of the observed variance. This work was supported in part by a program project grant from NICHD (HD-11681), and the report was prepared while J.J. Gillis was supported by NICHD training grant HD-07289.     

Training of component reading skills

Fifteen reading-disabled boys, classified according to reading subskill deficits, formed three subgroups: Oral Reading, Associative, and Sequential. On the rationale that training procedures emphasizing accuracy and speed of response to letters, syllables, and words would improve reading skills, the children were trained daily for two and one-half months. Two schedules of testing and training allowed for an untrained control group and a follow-up group. The results indicated that the computer-assisted training procedures were not only effective in improving component reading skills, but in addition there was a transfer of training to achievement measures of reading word recognition. This study lends support to the hypothesis that training according to subgroup classification, using training procedures which incorporate an application of the automaticity theory and a combination of task-analytic and process-oriented models, is an effective training approach for reading-disabled children. This research was funded by a grant from the Toronto Hospital for Sick Children Foundation, Toronto, Canada, and a scholarship from the Natural Science and Engineering Research Council, Ottawa, Canada.     

Colorado reading project: Longitudinal analyses

Extensive psychometric test data were obtained from two independent samples of reading-disabled and control children: 70 probands and 75 controls tested on two occasions over an average interval of 4.2 years, and 35 probands and 22 controls tested on three occasions over an average interval of 8.6 years. When composite measures of reading performance and symbol-processing speed were subjected to mixed-model multivariate analyses of variance, significant effects due to group (reading-disabled versus control) and time (i.e., test session) were obtained in both samples, and a significant group-by-time interaction was obtained for the sample tested on three occasions. In general, rates of change in reading performance are highly similar for reading-disabled and control children. However, with regard to symbol-processing speed, differences between the two groups increase as a function of age. Although no evidence was obtained for differential longitudinal stability of either composite measure in reading-disabled and control children, results of a multiple regression analysis suggest that reading deficits during middle childhood are highly predictive of later reading problems, even into early adulthood. This work was supported in part by a program project grant from the NICHD (HD-11681). The invaluable contributions of staff members of the many Colorado school districts and of the families who participated in the study are gratefully acknowledged.     

Effectiveness of Four Supplemental Reading Comprehension Interventions

Abstract

This article presents evidence from a large-scale randomized controlled trial of the effects of four supplemental reading comprehension curricula (Project CRISS, ReadAbout, Read for Real, and Reading for Knowledge) on students’ understanding of informational text. Across 2 school years, the study included 10 school districts, more than 200 schools, and more than 10,000 fifth-grade students. Schools interested in implementing 1 of the 4 supplemental curricula were randomly assigned to 1 of 4 treatment groups or to a control group. The impact analyses in the study's first year revealed a statistically significant negative impact of Reading for Knowledge on students’ reading comprehension scores and no other significant impacts. The impact of ReadAbout was positive and significant in the study's second year among teachers with 1 year of experience using the intervention.     

Familial history of reading difficulty is associated with diffused bilateral brain activation during reading and greater association with visual attention abilities

Reading difficulty (RD; or dyslexia) is a heritable condition characterized by slow, inaccurate reading accompanied by executive dysfunction, specifically with respect to visual attention. The current study was designed to examine the effect of familial history of RD on the relationship between reading and visual attention abilities in children with RD using a functional MRI reading task. Seventy-one children with RD participated in the study. Based on parental reports of the existence of RD in one or both of each child’s parents, children with RD were divided into two groups: (1) those with a familial history of RD and (2) those without a familial history of RD. Reading and visual attention measures were collected from all participants. Functional MRI data during word reading was acquired in 30 participants of the entire cohort. Children with or without a familial history of RD demonstrated below-average reading and visual attention scores, with greater interaction between these measures in the group with a familial history of RD. Greater bilateral and diffused activation during word reading also were found in this group. We suggest that a familial history of RD is related to greater association between lower reading abilities and visual attention abilities. Parental history of RD therefore may be an important preschool screener (before reading age) to prompt early intervention focused on executive functions and reading-related skills.     

The Double-Deficit Theory of Reading Disability Does Not Fit All

The double-deficit theory of reading disability (Wolf & Bowers, 1999) was examined in a sample of 56 reading-disabled and 45 normal-reading elementary school children (aged 8 to 11). As hypothesized, the two groups differed markedly on all phonological analysis tasks and on rapid continuous naming of digits and letters (the double deficits), but they differed as well on orthographic tasks, attention ratings, arithmetic achievement, and all WISC-III factors except perceptual organization. Within the reading-disabled (RD) sample, children in the double-deficit subgroup were no more impaired in reading and spelling than those with a single deficit in phonological analysis, and those with a single deficit in rapid naming were no more impaired than those with neither deficit. Multiple regression analyses suggest that a multiple causality theory of RD is more plausible than a double-deficit theory.     

Effects of an Animal-Assisted Intervention on Reading Skills and Attitudes in Second Grade Students

Reading skills are an important component of academic success for school-age youth, and are associated with increased academic performance and positive attitudes about school. The presence of an animal appears to reduce stress during reading. Therefore, the goal of this study was to assess the feasibility and effects of a 6-week after-school canine-assisted reading program in a public elementary school setting. Second-grade students were randomized to either an intervention group (n?=?14) in which they read to a registered therapy dog for 30 min once weekly for 6 weeks or a control group (n?=?14) with a standard classroom curriculum. Children’s reading skills were assessed biweekly and attitudes about reading were assessed pre- and post-intervention. The 6-week after-school canine-assisted reading program was feasible. Reading skill scores did not change significantly for either group. Although scores on recreational reading attitudes also did not change significantly for either group, the academic reading attitudes scores increased significantly in the intervention group (p?=?.002), but not in the control group (p?=?.06). These results support the benefits of an animal-assisted intervention for child literacy on children’s attitudes about reading and can inform future programs evaluating reading programs that include dogs.     

Cluster analytic classification of reading disability subtypes

Cluster analysis was employed to identify subtypes of reading disability in a sample of 140 reading-disabled children using factor scores obtained from a battery of psychometric tests. Preliminary results suggested the existence of three subtypes, but closer scrutiny of the data indicated that individual differences are more accurately characterized by continuity in the measurement space. This result demonstrates the need for detailed validation of findings from applications of cluster analysis. Despite the absence of homogeneous subtypes, the characterization of individual strengths and weaknesses on psychometric measures may nonetheless be important for diagnosis and remediation in the educational setting.Behavioral Research Institute     

Curriculum bias and reading achievement test performance

The overlap of words specifically taught in reading textbooks with the contents of standardized reading achievement tests may be a source of bias that is frequently overlooked in psychoeducational assessments. This study compares the standardized achievement test performance of 62 second graders receiving instruction in two different reading curricula (Open Court and Houghton-Mifflin) to determine whether either curriculum generates different quantitative estimates of reading achievement. Reading subtest scores derived from the Kaufman Test of Educational Achievement-Brief Form (K-TEA), the Wide Range Achievement Test-Revised (WRAT-R), and the Reading Recognition and Reading Comprehension subtests from the Peabody Individual Achievement Test (PIAT) were examined. Grade level equivalents and scaled scores from the California Achievement Test (CAT) were also examined. Three Curriculum × Test repeated measures ANOVAs were conducted using grade level scores (2×7), standard scores (2×4), and CAT scaled scores (2 × 5) as dependent measures. A significant Curriculum × Test interaction was identified, suggesting differences among tests in estimates of reading ability as a function of the reading program.     

Age-related changes in reading attitudes of young children: a cross-cultural study

The Preschool Reading Attitudes Scale (PRAS) was administered to 2201 young children, from three to five years of age, in early childhood programs from several regions of the United States. The scale is categorized into four areas related to children's reading environment. School Reading Activities, Non-school Reading Activities, Library Reading Activities and General Reading Activities. A validation sample revealed highly significant differences at all age levels between students receiving positive and negative teacher ratings of reading attitudes. The basic design involved three factors, age, sex, and ethnicity, and an analysis of variance was applied to total scores and subscores. The results showed significant outcomes for age and ethnicity, in addition to an age X ethnicity interaction. The results suggest that there are significant attitudinal differences between three-year-olds as opposed to four- and five-year-olds as well as age dependent differences among the ethnic groups.     

The Effects of Pre‐School Experience on Reading Attainment: a four year cross‐sectional study

This paper examines the reading attainments of a sample of Year 2 children who had one of three types of preschool experience. The results of a 4‐year cross‐sectional study of a sample of all Year 2 children (n = 834) from six randomly selected primary schools within one Local Education Authority (LEA) are presented. The children had attended nursery or playgroup or experienced no preschool provision outside the home: they were not matched for social background. Pupils’ scores on The Primary Reading Test (PRT) [France, N. (1981) The Primary Reading Test (Windsor, NFER/Nelson] are compared over the 4 years, as are the reading Standardised Assessment Task (SAT) scores of the last two cohorts. Results are not clear cut. For 3 of the 4 years, the group with no‐preschool experience performed significantly less well than at least one of the other two groups with some type of preschool experience on the PRT. The SAT levels of nursery children were significantly higher than those of the other two groups. Conclusions, based on such a small study, are tentative. It appears that preschool provision has an effect on children's reading attainments and that this is still significant in Year 2. The validity of the SAT is considered as a factor in the relative reading attainments of the three groups.     

Parents’ reading history as an indicator of risk for reading difficulties

Children from families whose members have reading impairments are found to be poorer performers, take less advantage of instruction, and require more time to reach the reading level of children whose relatives are good readers. As a family’s reading history may not be available, a self-report of reading abilities is used to identify children’s background. In this paper, we explored the contribution of phonological, literacy, and linguistic abilities and reported parental reading abilities to predict reading achievement at the end of the school year in a Spanish sample. Children who were starting to read were assessed in a variety of oral language, phonological, and literacy tasks at the beginning and end of the school year. Parents filled out a self-report questionnaire about their reading abilities. Their answers were used to assign children to good or poor reader parent groups (GRP vs PRP). A logistic and ROC analysis were used to assess the variables’ discriminative capability, considering literacy scores at the end of the year as a measure of reading achievement. GRP children obtained higher scores than PRP children did. Performance on tasks of rapid naming assessment (RAN) letters (78.6%), Word Reading (75.7%), and Deletion (75.6%) were the most accurate predictors of children’s reading achievement. IPRA showed slightly lower accuracy (73.8) than did the behavioral measures and as high specificity as RAN letters (96.2%), similarly to the percentages found in previous studies. Although behavioral measures were shown as the best predictors, parents’ self-reports could also provide a quick estimation of family risk of difficulties in literacy acquisition.     

Convergent and discriminant validity of the mental processing scales of the Kaufman Assessment Battery for Children

Convergent and discriminant validity of the Mental Processing Scales of the Kaufman Assessment Battery for Children (K-ABC) were examined using 51 first-grade children. Convergent validity was assessed using the Reading Recognition and Comprehension subtests of the Peabody Individual Achievement Test. Discriminant validity was assessed using a measure of anxiety/self-esteem, the Child Anxiety Scale, and a measure of hyperactive behavior, the Hyperactivity scale of the Achenbach Child Behavior Checklist. Results supported the convergent validity of the K-ABC; correlations with reading achievement were fairly large. The discriminant validity received only partial support. The K-ABC did not correlate with the Child Anxiety Scale, but did show rather large correlations with the measure of hyperactive behavior. Implications for understanding what the K-ABC Mental Processing Scales are measuring are discussed.     

Undergraduates’ text messaging language and literacy skills

Research investigating whether people’s literacy skill is being affected by the use of text messaging language has produced largely positive results for children, but mixed results for adults. We asked 150 undergraduate university students in Western Canada and 86 in South Eastern Australia to supply naturalistic text messages and to complete nonword reading and spelling tasks. The Australian students also completed two further real word and nonword reading tasks, a spoonerisms task, a questionnaire regarding their reading history, and a nonverbal reasoning task. We found few significant correlations between literacy scores and both use of textisms (such as u for you) and measures of texting experience. Specifically, textism use was negatively correlated with spelling for the Canadian students, and with scores for timed nonword reading, spoonerisms, and Adult Reading History for the Australian students. Length of phone ownership was negatively correlated with spelling (Canadians), but positively correlated with Word Attack scores (Australians), whereas daily message sending volumes were negatively correlated with Word Attack scores (Australians). Australian students who thought that using textisms was more appropriate had poorer nonword reading and reported having had more difficulty learning to read, than those who found it less appropriate. We conclude that there is inconsistent evidence for negative relationships between adults’ use of textisms and their literacy skills, and that these associations may be influenced by attitudes towards the appropriateness of textism use. A model of the potential relationship between adults’ textism use and literacy skills is presented.     

An Experimental Study of Formal Reading Instruction at the Kindergarten Level

Abstract

The purpose of the study was to investigate the effects of formal reading instruction on kindergartners with respect to reading achievement, attitude toward reading, and attitude toward school.

Altogether 220 children, classified on intelligence and reading readiness variables, were randomly assigned to formal reading and readiness programs for four months. Criterion data respecting to achievement and attitudes were collected by means of the California Reading Test and constructed attitude inventories.

Analyses of data reveal that in terms of reading achievement, the reading program was more effective than the readiness program, but that attitudes toward school and reading were a function of intelligence and reading readiness when attitudes were measured by a teacher-reporting scale. When measured by a pupil self-reporting scale, attitudes were a function of the type of instruction, with children in the readiness program showing more favorable attitudes.     

Reading Recovery in Context: implementation and outcome

Reading Recovery is a school‐based preventive strategy designed to reduce the number of children with reading and writing difficulties. This study evaluated the implementation of Reading Recovery in 12 New Zealand schools. Target (Reading Recovery) and Comparison pairs of children were identified through the Reading Recovery procedures operated by each school. Results indicated that very few schools adhered closely to all recommended entry and discontinuation criteria. Results for Target and Comparison children's reading progress up to the time of discontinuation are highly consistent with results reported by Clay (1985), with clear gains in favour of Target children. However, these gains had reduced considerably by the time of follow‐up. Data suggest that programme gains were greatest for children entering the programme at the lowest reading levels. Outcomes are discussed in terms of the need for better articulation between Reading Recovery teachers and regular classroom teachers.     

An operational definition of learning disabilities (cognitive domain) using WISC full scale IQ and peabody individual achievement test scores

An operational index of discrepancy to assist in identifying learning disabilities (LD) in the cognitive domain was derived using the Full Scale IQ, Wechsler Intelligence Scale for Children (Wechsler, 1949, and relevant subtest scores on the Peabody Individual Achievement Test (PIAT) (Dunn and Markwardt, 1970. The index was applied to all legally identified LD children (N = 60) of a Michigan county who were in the LD program (1% of the total elementary school population of 6000 children). Of the 50 males and 10 females (mean age: 9 years 2 months; mean IQ: 91), the index identified 74% and 30% respectively as may be LD in the cognitive domain. This comprised 67% of the 60 children, or 2/3 of 1 % of the total elementary school population. Of the 67% may be LD children, 93% had discrepancy low PIAT subtest scores in Reading Recognition, 88% in Reading Comprehension, 83% in Spelling, and 52% in Arithmetic. Considerable caution should be exercised when classifying children, especially females, as LD.     

The cognitive levels test: Its relationship with reading and mathematics achievement

Any instrument designed to measure broad cognitive ability is expected to correlate substantially with valid measures of academic achievement. This report describes an investigation designed to evaluate the relationship between the Cognitive Levels Test, a newly available instrument, and two tests of academic achievement that have been widely used for nearly two decades: the Woodcock Reading Mastery Tests and the KeyMath Diagnostic Arithmetic Test. The study included children in grades K-2 who were enrolled in a remedial summer school program. The results showed the Cognitive Levels Test (Cognitive Index) to be rather highly correlated with the KeyMath Diagnostic Arithmetic Test Total score (r=.72) and moderately correlated with the Woodcock Reading Mastery Tests Total Reading score (r=.55). A repeated measures analysis of variance comparing standard scores for the Cognitive Levels Test with those of the Woodcock Reading Mastery Tests indicated few mean differences between the two sets of scores. Implications concerning the validity of the Cognitive Levels Test were discussed.     

Locus of control and reading attitude

The relationships between three measures of locus of control and eight dimensions of reading attitude were investigated for a sample of 431 inner-city children. The sample included the intermediate grade children enrolled in the 20 regular classrooms of the three elementary schools from the Columbus, Ohio, Public Schools. Correlation coefficients were computed between locus of control scores and the eight dimensions of reading attitude. Reading Anxiety showed a significant relationship with the I- score. This finding suggests that inner-city children who are willing to accept personal responsibility for negative events in their lives also tend to experience more anxiety about their reading. The other seven dimensions of reading attitude were not significantly related to internality scores.
