A comparison of the WISC and WISC-R

So as to compare the results of the WISC and WISC-R, both instruments were administered to 58 children randomly selected from a school population of 583. All administration and scoring was performed by the same psychologist, with a two-month interval separating the administrations for each child. All IQs were significantly higher (p <.01) on the WISC, with the Performance difference being greater than the verbal difference. Also, 8 of the 10 required subtest scaled scores were significantly greater (p <.05) on the older instrument. Regression equations were obtained to predict WISC-R IQs from WISC scores.     

WISC and WISC-R correlates of academic achievement

WISC and WISC-R test results were correlated with achievement test scores and school grades of 36 children who had completed two years of school. Global intelligence estimates from both scales correlated at significant levels with all achievement test measures. Individual subtests from the two scales were unevenly correlated with grades in specific school subjects over both school years. Data suggest that while the two scales may be grossly equivalent as global predictors of school achievement, the individual subtests from the two scales may not correlate equivalently with specific external criteria such as school grades.     

Matched pair comparison of WISC and WISC-R scores

Both the WISC and the WISC-R were administered to 54 children, with one half taking the WISC first and the other 27 taking the WISC-R first. Differences between mean subtest scaled scores and mean IQs were found to be influenced by the sequence of the tests, although all mean scores were higher on the second test when the WISC-R was given first. Data were presented suggesting the WISC-R given first tends to raise WISC scores, and WISC given first yields scores on the WISC-R which are essentially similar, effectively counsteracting the more “difficult” scoring for the WISC-R.     

A comparison of factor structures of the WISC and WISC-R

The present study compared two- and three-factor solutions for the 12 subtests of both the WISC and WISC-R for a sample of 164 black, white, and Latino children aged 7 to 15 referred to school psychologists because of concerns about their intellectual ability. The results indicated that the factor structures of the WISC and WISC-R for the same group of subjects are quite similar. They are almost identical in the factors of verbal comprehension and perceptual organization. However, a difference was noted in the third factor of freedom from distractibility.     

Structured extracurricular activities among adolescents: Findings and implications for school psychologists

One factor that contributes to adolescent positive mental health is active engagement. Engagement is defined as any activity that is initiated to attain an outcome. In general, two forms of activities exist that correspond with engagement: solitary, non‐structured, and non‐cooperative pursuits, often without adult supervision (e.g., playing video games, watching television) and highly structured, collaborative activities that are under the guidance of a competent set of adults (i.e., structured extracurricular activities, or SEAs). Although large amounts of time spent in unstructured activities is related to negative psychosocial outcomes, participation in SEAs has been related to a variety of positive outcomes for students. This paper reviews current research regarding adolescent participation in SEAs and its effects on academic and personal‐social variables (i.e., self‐concept, life satisfaction), as well as potential preventive effects for youths considered to be “at‐risk” for negative developmental outcomes. The paper also examines research investigating the potential benefits and shortcomings of different types of SEAs. Finally, suggestions for future research and school‐based preventive intervention are presented. © 2004 Wiley Periodicals, Inc. Psychol Schs 41: 31–41, 2004.     

Factitious disorder in school settings: A case example with implications for school psychologists

Factitious disorder is a condition that has received considerable attention in the medical literature yet is not fully recognized in the school setting. School psychologists can provide important data and observations that can facilitate early identification of this disorder. This article describes a case example of factitious disorder that was identified in the school setting. Symptoms of the disorder are presented, as are the differential diagnoses that must be considered. Specific recommendations for the school psychologist regarding identification, coordination with medical teams, interventions, and ethical and legal obligations are included. © 2000 John Wiley & Sons, Inc.     

Investigation of the WISC-R for use with retarded children: Correlation with the 1972 Stanford-Binet and comparison of WISC and WISC-R profiles

A group of 80 mentally retarded youngsters, aged 6 to 16, was tested on the WISC-R, primarily to assess the continuity of measurement between the old and new WISCs. The WISC-R IQs correlated .65 to .82 with Stanford-Binet IQ for a subsample of 45 children, resembling the coefficients between the 1949 WISC and the Binet for retarded groups. In addition, the WISC-R test profiles for the 80 children corresponded closely to the WISC test profiles for many retarded samples. Thus, there was evidence to support the continuity of the WISC-R with its predecessor for retarded populations.     

Juggling personal life and professionalism: Ethical implications for rural school psychologists

Rural communities often contain unique features that separate them from more urban communities. Although a body of research is devoted to ethical considerations for psychologists working in rural communities as a whole, much less current research is focused on working in rural schools. This paper specifically highlights ethical considerations regarding competence, multiple relationships, and confidentiality. Given that access to services within the community may be limited, school psychologists may encounter cases that are outside of their area of competence. Furthermore, due to the interconnectedness present in many rural communities, psychologists frequently have multiple relationships with those whom they have professional contact. Confidentiality may be compromised when families and school personnel also have multiple relationships. These factors must be considered by psychologists working in rural schools, and steps must be taken at the outset of practice to ensure ethical compliance. More specific means of obtaining this compliance are discussed in this paper.     

Direct comparisons of the factor structures of the WISC and the WISC-R

The factor structures of the WISC and the WISC-R were compared, using the data for age groups 7.5, 10.5, and 13.5 years in the two standardization samples. The results for three different types of solution—hierarchical, multiple-group, and principal-factor—agreed in demonstrating that the structures of the two scales are as similar as the structure of either scale is for different age groups.     

Parent role characteristics: Parent views and their implications for school psychologists.

This research examined the parent role as perceived by a large number of parents of school-age children in New Hampshire. The results reveal that these parents readily describe a parent role using the same characteristics that emerge from the research literature. More importantly, the subjects consider each of the six parent role characteristics as differentially important at different stages in children's development. The implications of this research for school psychologists are many, including, for instance, assessment, consultation, and intervention.     

Life satisfaction in children and youth: Empirical foundations and implications for school psychologists

A central component of positive psychology is subjective well‐being (SWB). One facet of SWB receiving increased research attention is children's perceived quality of life (PQOL). Existing research related to child and youth PQOL is reviewed, followed by a discussion of the implications of the research for school psychology practice. Research with children and adolescents reveals that PQOL has a wide ranging nomological network including personality, environmental, and activity variables. Furthermore, PQOL appears to mediate relationships between the environmental experiences of youth and problem behavior. Implications are discussed within the context of calls for greater attention by school psychologists to prevention, non‐traditional assessment, direct service, consultation with teachers and parents, diversity issues, and the science‐practice connection. © 2004 Wiley Periodicals, Inc.

A longitudinal comparison of the WISC and WISC-R with special education pupils

The purpose of this study was to determine the degree of comparability between the WISC and the WISC-R over time. Hypotheses were tested using a sample of 276 mildly mentally handicapped children enrolled in special education classes who had received a WISC (Trial 1) and a WISC or WISC-R (Trial 2) after an interval of approximately three years. The sample was grouped on the basis of test administered in Trial 2. Group I contained those children who received the WISC on Trial 2 and included 183 children, of whom 121 were males and 62 were females. Mean age at time of initial testing was 8–10; mean age at second testing was 11–8. Group II was composed of 93 children who had been posttested on the WISC-R and included 72 males and 21 females. Mean age at initial testing was 9–5; mean age at posttest was 13–0. The study was conducted in five school districts and one county department of education. Verbal IQ, Performance IQ, and Full Scale IQ for both instruments administered were transcribed from the special education folders of the children. The design used to test hypotheses was repeated measures analysis of variance. Data analysis resulted in rejection of the hypotheses that the WISC-R yields mean Verbal, Performance, and Full Scale IQ scores greater than or equal to the corresponding mean IQ scores of the WISC. It was concluded that the WISC-R may unfairly penalize special education children who are reevaluated with this instrument. Fluctuations in IQ scores due to the instrument of measurement must be recognized, and appropriate action should be taken to insure that children are evaluated for special class placement on comparable bases.     

Curriculum and instruction for the gifted: The role of school psychologists

This paper explores the school psychologist's role in the academic and psychosocial development of students identified as gifted and talented via curriculum. Given the school psychologists' assessment expertize, they can inform the identification to service placement process for students, including advocacy for curricular and instructional opportunities that best meet the student's needs. We discuss modern conceptualizations of giftedness and talent development, the function of curriculum and instruction in meeting the needs of students who are gifted and the school psychologist's role in identifying which curricular adaptations are appropriate for students based on learner data. We also discuss how a school psychologist can work with educators to support the needs of twice exceptional learners and gay, lesbian, bisexual, transgender and questioning students and recommend professional learning opportunities for school psychologists to remain abreast of current issues in gifted education.     

A comparison between the WISC and WISC-R among a clinical referred population

This study compared the three scales of the WISC and the WISC-R for degree of intercorrelation. The differences among scores and among variances were also computed for the two tests. Fifty-eight subjects from a clinical referred population were studied, including children classified as EMR, Learning Disabled, Emotionally Disturbed, and children in regular classrooms. Results included significant correlations in all cases, no systematic changes in variance, and significantly lower IQs on the WISC-R for all children in this sample, except the EMRs.     

A comparison between the WISC and WISC-R among educable mentally retarded students

The study compared differences and similarities between WISC and WISC-R scores for 48 ten- and thirteen-year-old EMR students, who were matched according to sex and race. The WISC-R yielded significantly lower VS, PS, and FS IQ scores than the WISC for this predominantly rural Georgia population. The FS IQ scores from the WISC-R averaged 7.5 points lower than the WISC FS IQs, with similar differences noted for VS and PS scores. There was no significant difference in FS IQs between the two age groups. Results suggest that many children classified as “Borderline” or slightly above by the WISC will be classified as “Mentally Deficient” by the WISC-R.     

Parental refusal to consent for evaluation: A legal analysis with implications for school psychologists

The decision to begin the process for special education eligibility has complexities impacting children, parents, teachers, and schools. The Individuals with Disabilities Education Improvement Act (IDEA) eligibility provisions specify the need to obtain consent prior to evaluation and options when consent cannot be obtained. School psychologists may encounter parents who are reluctant to provide consent or parents who may seek to condition their permission. The reasons for parent refusal to consent to evaluation are analyzed in a review of administrative and judicial decisions published in the Individuals with Disabilities Education Law Report between 2004 and 2008. Possible parent reactions to the request for evaluation are discussed, and guidelines for school psychologists encountering reluctant parents are provided. © 2012 Wiley Periodicals, Inc.     

Comparability of the WISC and the WISC-R in normal children of divergent socioeconomic backgrounds

WISC and WISC-R IQs of two groups of normal ten-year-old children from divergent socioeconomic backgrounds (N = 36) were compared in a counterbalanced research design. Generally, all WISC mean IQs were higher than the WISC-R mean IQs for both groups of children. Significantly higher WISC IQs were obtained on the Verbal and Full Scales of the low socioeconomic group and on the Performance and Full Scales of the high socioeconomic group. Correlations between tests for Verbal, Performance, and Full Scale IQs were.95,.79, and.91 for the low socioeconomic group, and.84,.57, and.87 for the high socioeconomic group. Although practice effects did not appear to significantly affect IQs of the low socioeconomic group, various practice effects were observed in the high socioeconomic group. Negative effects were observed for both WISC and WISC-R on the Verbal Scale, whereas positive effects were observed on both Performance and Full Scales in this group. Analysis of simple effects reveals that WISC and WISC-R IQs did not differ significantly upon first administration, but were significantly different upon second administration. Conclusions were drawn that while WISC-R yields a lower IQ estimate than WISC for children of lower ability, results were not so clear for the children of higher ability, due to practice effects which disproportionately favor increases on WISC IQs upon second administration. The greater practice effects found on the WISC have implications for comparisons of the two tests in counterbalanced research designs. Simple randomized or treatment-by-levels design may be more useful in comparisons of the WISC and the WISC-R because of the bias introduced by counterbalanced designs.
