Processing of rapid auditory stimuli in school-age children referred for evaluation of learning disorders

Tallal hypothesized that reading disabled children have a domain-general deficit in processing rapidly occurring auditory stimuli that degrades speech perception, thereby limiting phonologic awareness and thus reading acquisition. She predicted they would be disproportionately affected by rapidly presented auditory stimuli. In this study, one hundred 7- to 11-year-old children with learning impairment (LI) and 243 non-learning impaired (NLI) children were evaluated on a two-tone auditory discrimination paradigm. LI committed more errors, but effects of timing were comparable. The same result was obtained for a subsample of good and poor readers. Task performance predicted reading, spelling, and calculation. Neural processes underlying perception of speech and other auditory stimuli may be less effective in poor readers; however, contrary to Tallal's hypothesis, rate may not be specifically affected.     

Characteristics of children referred for evaluation of school difficulties who have adequate academic achievement scores

Forty children (7 to 11 years old) referred for evaluation of learning problems, who had scores within the normal range on standardized measures of academic achievement, were compared to 81 similarly referred children who had scored low (< 90) on at least one measure of academic achievement. We tested the hypothesis that children with normal achievement scores who are referred for evaluation of learning problems show neuropsychological profiles comparable to those of children with low achievement. Referral problems, school history, IQ, academic achievement, and neuropsychological function were evaluated. Referred children with normal achievement scores came from more advantaged backgrounds and had less intensive academic interventions, higher IQs, and better decoding skills. Nonetheless, the two groups showed similar neuropsychological profiles. Vulnerability to complexity and decreased automaticity were prominent. Normal-range achievement test scores among children referred for evaluation should not be regarded as indicating absence of neurodevelopmental vulnerability.     

A psychoeducational program dealing with child abuse for elementary school children

This paper reports the outcome of an attempt to teach children in grades 5 and 6 about child abuse and neglect. The Child Abuse Component of the Human Relations Program described and evaluated here is a unique effort to provide children with an opportunity to discuss and learn about this aspect of family violence. An impact assessment was conducted by documenting possible changes in student knowledge and attitudes regarding child abuse as a result of exposure to the Child Abuse Component of the Human Relations Program. The test group of children consisted of 315 boys and girls in grades 5 and 6. A comparison group of 298 children was closely matched with the test group on the basis of age and sex. These groups were formed by randomly selecting 12 teachers from all teachers agreeing to use the Component and 10 teachers choosing not to employ the Component. The students in the classrooms of these teachers received the same curriculum for their grade level with the exception of the field-test group additionally receiving the Component. Selected child abuse knowledge, attitude, and personality (security) measures were given all subjects in a post-test with comparison group research design. Teacher knowledge and attitude were also assessed. The results of the data analysis, teacher, and special observer reports suggest that the Component was effective in meeting its objectives and was not disturbing to test subjects. Apparently, the test children profited by experiencing the Component mainly because of the opportunity it provided for class discussion. Moreover, the knowledge levels and interest of the children in both groups was seriously underestimated.     

Factor structure of the K-ABC for referred school children

Previous factor analyses of the K-ABC for school-age children have offered varying degrees of support for the test, depending on which subtests have been analyzed. Further, most previous analyses have involved only children from the standardization sample. Here, K-ABC scores for 585 school-age children referred for psychological evaluation were factor analyzed. Results of the analysis of K-ABC MP tests were quite consistent with those of previous analyses and with the structure of the test itself. The factor structure of the MP and Achievement tests together was also consistent with previous analyses and, like those analyses, was somewhat less consistent with the theoretical structure of the K-ABC; the factors found could be interpreted from several perspectives. As in analyses of the standardization data, the Achievement tests appear to be better measures of general intelligence for referred children than do the MP scales. Thus, while it appears that the K-ABC factor structure is quite consistent for both normal and exceptional children, the meaning and names of factors found are open to interpretation.     

The usefulness for psychoeducational evaluation of preassessment screening for sensory-motor and perceptual encoding deficits

Information-processing theory and research suggest that a careful examination of the input levels of processing is an essential prerequisite to the accurate assessment of higher levels of cognition. This paper describes a preassessment screening procedure to evaluate sensory-motor and perceptual encoding processes of children referred for psychoeducational assessment. In addition, an investigation of the diagnostic utility of the screening procedure is presented. Assessment procedures and outcomes for 18 children screened for encoding deficits were compared with those of a comparison group of 23 children whose psychoeducational evaluation at the same clinic did not include the screening procedure. Results demonstrate the potential usefulness of preassessment screening for encoding deficits to inform and supplement traditional psychometric measures of intellectual functioning.     

Factor structure of psychoeducational and neuropsychological measures of learning-disabled children

This study investigated the factor structure of psychoeducational and neuropsychological measures used in the assessment of learning-disabled children. The Wechsler Intelligence Scale for Children-Revised, the Halstead-Reitan Neuropsychological Battery, the Peabody Picture Vocabulary Test, and the Wide Range Achievement Test were administered to 934 males and females between the ages of 8 and 16 years. A principal-components analysis with varimax rotation indicated the existence of seven factors: Verbal Reasoning, Academic Achievement, Visual-Perceptual Organization, Developmental, Visual-Motor Speed, Spatial Memory, and Attention and Concentration. Three factors provided new information about the functioning of learning-disabled children that may need to be considered before comprehensive identification and placement decisions can be offered. Results of this study lend support to the notion of utilizing neuropsychological measures as an adjunct to traditional psychoeducational assessment.     

Relationship between WISC-R and WRAT in children referred for learning difficulties

Correlations between the WISC-R Full, Verbal, Performance, and Freedom from Distractibility Scale IQs, WISC-R subtest scaled scores, and Wide Range Achievement Test Reading, Spelling, and Arithmetic standard scores were computed for a sample of 114 children (64 boys, 50 girls), aged 6 to 16 years, who were referred for psychological evaluation because of academic or learning difficulties. The Full Scale IQ, Verbal Scale IQ, and Freedom from Distractibility IQ correlated moderately with the three achievement area standard scores (rs of .48 to .59). However, the Performance Scale IQ correlated minimally with reading and spelling scores (rs of .26 and .27), but moderately with arithmetic scores (r = .40). The results support the concurrent validity of the WISC-R.     

The diagnostic utility of Bannatyne's recategorized WISC-R scores with children referred to a developmental evaluation center

The diagnostic utility of Bannatyne's recategorized WISC-R scores in differentiating among children referred to a developmental evaluation center was evaluated. The results failed to provide support for the diagnostic utility of recategorized WISC-R scores in general and for the pattern spatial 〉conceptual〉sequential in particular. The findings are discussed in terms of the caution necessary regarding the empirical basis for diagnostic inferences and the need for replication and/or evaluation of other potential measures with well-defined clinical groups.     

Children referred for possible sexual abuse: medical findings in 2384 children

OBJECTIVE: The goal of this study was to compare rates of positive medical findings in a 5-year prospective study of 2384 children, referred for evaluation of possible sexual abuse, with two decades of research. The prospective study summarizes demographic information, clinical history, relationship of perpetrators, nature of abuse, and clinical findings. The study reports on the results by patterns of referral and the medical examination. RESULTS: There were 2384 children evaluated in a tertiary referral center between 1985 and 1990 for possible sexual abuse. Children were referred after they disclosed sexual abuse, because of behavioral changes or exposure to an abusive environment, and because of possible medical conditions. A total of 96.3% of all children referred for evaluation had a normal medical examination; 95.6% of children reporting abuse were normal, 99.8% who were referred for behavioral changes or exposure to abuse were also normal. Of the 182 children referred for evaluation of medical conditions, 92% were found to be normal at the time of examination by the Child Advocacy Center. The remaining 15/182 (8%) that were found to be abnormal were diagnosed with sexually transmitted diseases, acute or healed genital injuries, and were 17% (15/88) of the total cases found to have medical findings diagnostic of abuse. Interviews of the children indicated that 68% of the girls and 70% of the boys reported severe abuse, defined as penetration of vagina or anus. Penetration was associated with a higher percentage of abnormal findings in girls (6%) compared to 1% of the boys. The relationship of the abuser impacted on the severity of the abuse. CONCLUSION: Research indicates that medical, social, and legal professionals have relied too heavily on the medical examination in diagnosing child sexual abuse. History from the child remains the single most important diagnostic feature in coming to the conclusion that a child has been sexually abused. Only 4% of all children referred for medical evaluation of sexual abuse have abnormal examinations at the time of evaluation. Even with a history of severe abuse such as vaginal or anal penetration, the rate of abnormal medical findings is only 5.5%. Biological parents are less likely to engage in severe abuse than parental substitutes, extended family members, or strangers.     

The assessment needs of families with children who are deaf and hard of hearing referred for an autism spectrum disorder evaluation

With the increasing prevalence of autism spectrum disorder (ASD), clinicians and schools are receiving a larger number of assessment referrals for eligibility or diagnostic clarification of ASD in children who are deaf and hard of hearing (D/HH). Meeting this increasing demand is often difficult given not all assessment professionals seek specialized ASD training and even fewer have experience working with D/HH children. Therefore, families are disadvantaged because of the lack of assessment professionals who specialize in both these areas. School psychologists without such experience are at-risk for misinterpreting or missing key diagnostic information. This study explored the assessment experiences of four families of D/HH children who have ASD. Hearing parents’ and D/HH parents’ perspectives were gathered to explore the family needs. An open-ended survey asked parents to recall the assessment techniques utilized during the process and relate how their child's language skills were accounted for by the clinician. Parent responses revealed interpreters were utilized for various reasons unique to each family. Families expressed difficulty finding ASD specialists who had experience working with D/HH children. This study highlights the importance of selecting a trained interpreter and emphasizes the need of more professionals who have experience assessing ASD in D/HH children.     

WISC-R performance of children referred to a university center for learning disabilities

This study compared the WISC-R performance of 40 children ranging in age from 6–6 to 15–10, referred to a university center for suspected learning disabilities, with that of two clinically defined groups of learning disabled children. The university center children were found to have WISC-R profiles similar to those of the learning disabled children, with higher overall levels of performance. It was speculated that these children avoid classification as learning disabled by virtue of possessing higher cognitive abilities than those children who are classified. Implications were raised concerning the role of university centers with children experiencing learning difficulties and the accuracy of parental perceptions of learning disabilities.     

A comparison of the PPVT-R and WISC-R with rural children referred for assessment

The present study investigated the relationship between the Revised Peabody Picture Vocabulary Test (PPVT-R) and the WISC-R for a naturally occurring sample of rural children referred for assessment (N = 53). The results indicated that the PPVT-R was highly correlated with WISC-R scale and subtest scores. Examination of a sub-sample of developmentally handicapped students revealed substantial reduction in correlational relationships as a function of reduced sample size and restricted range of general ability. While the PPVT-R was found to underestimate all three WISC-R scale scores, the discrepancy between the PPVT-R standard scores and the WISC-R Performance Scale score was the only statistically significant underestimation. Results are discussed in terms of prior research findings and implications for interpretation.     

Predictors of psychological recommendations in child protection evaluation

Child protection matters from an important social and legal challenge, in which psychologists may be called upon to address a series of questions relevant for judicial decision-making. In an explorative manner, the current study investigates variables that influence psychological evaluators’ recommendations in child protection cases. The data is based on a quantitative content review of 103 psychological evaluation reports, conducted at an institute of forensic psychology in Germany. Using bivariate and logistic regression analyses, the following predictors were analyzed in this study: Child-related factors, familial risk factors, and general custody criteria. The outcome measure was the evaluator’s recommendation regarding long-term placement of the child and long-term custody arrangements. Evaluators were more likely to recommend permanent foster placement if the child showed insecure or disorganized attachment patterns, especially when combined with developmental delays, or if the child was temporarily in institutional or foster placement at the time of evaluation. The results support the conclusion that the most important factors for psychological expert recommendations refer to the “harm of the child” criterion in terms of developmental and psychological maladaptation.     

Predictors of treatment outcome in sexually abused children

PROBLEM: This study evaluated the impact of child and family characteristics on treatment outcome of sexually abused children. METHOD: Forty-nine recently sexually abused 7- to 14-year-old children were randomly assigned to either abuse-focused cognitive behavioral therapy or nondirective supportive therapy, and assessed pre- and post-treatment using several standardized instruments. These included five measures of psychological symptomatology and four measures of child and family characteristics hypothesized to mediate treatment response. Correlational and multiple regression analyses were utilized to evaluate the impact of the following mediating factors on treatment outcome: Children's abuse-related attributions and perceptions; family cohesion and adaptability; parental support of the child; and parental emotional reaction to the child's abuse. RESULTS: Children's abuse-related attributions and perceptions and parental support of the child were strong predictors of treatment outcome in this population. CONCLUSIONS: Therapeutic attention to children's sexual abuse-related attributions and to enhancing parental support may be important factors in optimizing treatment outcome in 8- to 14-year-old sexually abused children.     

WISC,WISC-R,S-B L&M,WRAT: Relationships and trends among children ages six to ten referred for psychological evaluation

Thirty children ages 6-10 were selected who had been referred for psychological evaluation from the public schools. WISC-R was significantly lower than WISC FS IQs and similar to S-B L&M IQs (1972). Each scale predicts reading, spelling, and achievement in a significant manner. The use of the WISC-R over the WISC will rosult in greater numbers of children being classified as retarded.
