Comparability, reliability, and practice effects on alternate forms of the Digit Symbol Substitution and Symbol Digit Modalities tests

The present study examined the comparability of 4 alternate forms of the Digit Symbol Substitution test and the Symbol Digit Modalities (written) test, including the original versions. Male contact-sport athletes (N = 112) were assessed on 1 of the 4 forms of each test. Reasonable alternate form comparability was demonstrated through establishing normality of form distributions and conducting pairwise form comparisons of means, variability, and intraclass correlations. Nonetheless, alternate forms are likely an insufficient means of controlling practice in speeded measures at brief (1-2 weeks) retest intervals. Reliable change indices demonstrated that practice must be accounted for in individual retesting.     

Relationships between the Digit Symbol test and a noncoding motoric equivalent in assessments of brain-damaged patients

For 70 rehabilitation patients aged 17 to 85 yr. mean ratios of number of symbols coded to number copied were .48 for 10 persons (16 to 19 yr.) and .47 for 60 (20 to 69 yr.) which compares with .44 for normal subjects. Coding and copying are moderately correlated, and copying may be more sensitive to brain damage.     

Digit Symbol Substitution test performance: sex differences in a Hebrew-readers' health population

The Digit Symbol Substitution test is simple to administer and sensitive to individual differences related to cognitive performance. The present study evaluated sex-related differences in performance by a Hebrew reading sample. The test was administered to 275 men and 252 women (age range: 20-44 years). Hebrew women significantly scored higher than the men. Means which increased during four consecutive 30-sec. time periods of performance, was significantly greater for the women than the men. This finding indicates women were more effective on this pair-associated learning task than men.     

The sensitivity of the Bender-Gestalt Test as a screening instrument for neuropsychological impairment in older adults

We investigated the sensitivity of the Bender (1938) Visual-Motor Gestalt Test (BGT) using the Halstead-Reitan Neuropsychological Battery (HRB) as the criterion for cortical dysfunction. We studied 95 subjects over age 55 who had been diagnosed as having dementia or pseudodementia. Subjects were classified as mild, moderately, or severely impaired on the HRB and as impaired or unimpaired on the BGT. The results indicated that the BGT is less sensitive (36%) than was expected when used on an impaired geriatric population. The data further indicated that false negatives occurred more frequently with the BGT when individuals had mild neuropsychological impairment. Less frequent misclassifications occurred as the severity of impairment on HRB indices increased.

An index for specific learning disabilities of six signs or symptoms, taken as a group, is described. Preliminary work encourages cross-validation.     

Validity of the motor observation questionnaire for teachers as a screening instrument for children at risk for developmental coordination disorder

This study investigates validity of the Motor Observation Questionnaire for Teachers (MOQ-T) in 182 children aged 5-10years, 91 children referred for motor problems to a rehabilitation center and 91 comparison children. Performance on the MOQ-T was compared to performance on the Movement Assessment Battery for Children (M-ABC) and the Developmental Coordination Disorder Questionnaire (DCD-Q). Significant correlations were obtained between the MOQ-T and the DCD-Q (r=-.63), and the MOQ-T and the M-ABC (r=.57). The MOQ-T discriminated between children at risk for DCD and comparison children. Sensitivity of the MOQ-T was 80.5%, specificity 62% with the M-ABC as 'gold standard'. These results support the validity of the MOQ-T as a screening instrument for identification of children at risk for DCD.     

Wechsler Digit Span subtest: diagnostic usefulness with dyslexic children

The current study supports Levinson's contention (1988) that the diagnosis of dyslexia cannot be based solely on neurophysiological evidence but must be made in conjunction with reading and educational test scores. Contrary to much current research, in the present study specific WISC-R profiles are identified within a stringently defined subgroup of 57 9- to 12-yr-old dyslexic children. Well-defined subtest scatter can differentiate dyslexics from proficient readers. In particular, the Digit Span subtest, which is not routinely administered by psychologists or included in computing Verbal IQ, can be considered an important component of a diagnostic battery. Unexpectedly, Coding emerged with Digit Span as a third factor in a principal component analysis; statistically significant sex differences appeared on the Coding task. Findings appear to confirm the phonological encoding deficiencies displayed by dyslexics on the Digit Span subtest. This study strongly supports consideration of WISC-R subtest differences, along with correlated factors, neurophysiological and perceptual evidence, when diagnosing dyslexic children. Cross-validation is planned.     

Properties of the beck depression inventory as a screening instrument for adolescent depression

The utility of the Beck Depression Inventory (BDI) for identifying Major Depressive Episode was assessed with two samples of adolescents, 65 psychiatric hospital inpatients and 49 secondary school students. Diagnoses based on the Child Assessment Schedule served as criteria. With the school sample, a BDI screening score of 16 resulted in 100% sensitivity and 93.2% specificity. For the inpatient sample, a cutoff of 11 yielded a sensitivity of 81.5% and specificity of 52.6%. There was evidence of the BDI's convergent and discriminant validity for both samples. The results were consistent with the assertion that Major Depressive Episode is a sufficiently distinct diagnostic category in adolescence to be detected by a screening measure such as the BDI.This research was supported by grants to the first author from the National Research Council, and to the second author from the Graduate Students Association of Arizona State University. The authors express their appreciation to Camelback Hospitals and to Judson School for their cooperation in arranging for subject participation.     

An abbreviated PTSD checklist for use as a screening instrument in primary care

Although the importance of recognizing posttraumatic stress disorder (PTSD) in primary care has been well-established, routine screening for PTSD remains unfeasible for many primary care clinics because of the length of the available screening instruments. Thus, the purpose of this work was to develop and validate a brief screening tool for PTSD. In Study 1, four short forms of the PTSD Checklist-civilian version were identified that captured a majority of the variance in the measure. In Study 2, the performance of these short forms was evaluated in a separate sample of primary care patients. We found that both two-item and six-item versions have adequate psychometric properties for screening purposes and suggest that the selection of one version over the other depends on the specific needs of each primary care clinic.     

Psychometric properties of the Movement Assessment Battery for Children‐Checklist as a screening instrument for children with a developmental co‐ordination disorder

Background: The Checklist of the Movement Assessment Battery for Children (MABC) was developed to screen children for movement difficulties in the school situation. However, the psychometric properties of the Checklist have not been investigated in detail. Aim: The psychometric properties of the M‐ABC Checklist were investigated including its usefulness as a screening instrument. Samples: A group of 120 children, 6 to 11 years old, randomly selected from mainstream schools and a group of 64 children, 6 to 9 years old, referred for assessment of their motor functioning. Methods: A reliability analysis was performed to investigate whether the 48 items of the Checklist measure the same construct. Construct validity was investigated by means of a factor analysis. And lastly, the sensitivity, specificity and positive predictive value of the Checklist were investigated by comparing the performance of children on both the Test and Checklist of the M‐ABC. Results: The items of the Checklist measure the same construct. Seven factors were obtained after factor analysis, revealing that the Checklist measures a broad range of motor skills. The Checklist met the standards for sensitivity in all age groups, except in the 8‐year‐old group, where too many children with motor problems were not detected. With the exception of the 6‐year‐old children, specificity was poor. The positive predictive value was acceptable, except for the 7‐year‐old children. Conclusion: the Checklist proved to meet standards for reliability and most aspects of validity. Its use by teachers for screening children with movement difficulties can be recommended.     

Development and validation of a brief mental health screening instrument for newly incarcerated adults

The authors report the development and initial psychometric evaluation of gender-specific brief screening instruments to identify undetected psychiatric impairment on incarceration. Women and men completed the Correctional Mental Health Screen (CMHS), a 56-item screen derived from validated measures. Representative subsamples completed structured diagnostic interviews within 5 days. An 8-item screen for women and a 12-item screen for men identified inmates with current Axis I psychiatric disorders with 83% to 100% accuracy on the basis of cut points chosen to maximize negative predictive power. The CMHS showed evidence of incremental predictive utility compared with two previously validated correctional mental health screening measures with White and Black men and White women. Incremental validity was not supported with Black women, for whom the CMHS performed well in identifying true cases but not in ruling out noncases. Analyses of internal consistency, interrater, and retest reliability and convergent, discriminant, and criterion validity supported the psychometric status of the CMHS.     

The pediatric emotional distress scale: a brief screening measure for young children exposed to traumatic events

Introduced the Pediatric Emotional Distress Scale (PEDS), which was developed to quickly assess behaviors identified in empirical and theoretical literature as significantly elevated in children after experiencing traumatic events. The 21-item parent-report rating scale includes 17 general behavior items and 4 trauma-specific items. Factor analyses on the 17 items, with 475 two- to ten-year-olds (traumatic event exposure and nontraumatic event exposure), yielded 3 reliable factors labeled Anxious/Withdrawn, Fearful, and Acting Out. Factor and total scores were shown to have good internal consistency, and both test-retest and interrater reliability were at acceptable levels. Discriminant analyses demonstrated the PEDS could distinguish traumatic event exposure and nonexposure groups, although maternal education should be a significant consideration in interpretation. Future research with diverse populations who have documented trauma is needed to enhance the utility of the full PEDS scale.     

The SCL-90-R as a screening instrument for severe personality disturbance among outpatients with mood and anxiety disorders

Our objective was to examine whether the SCL-90-R, a widely used self-report measure of distress and psychopathology, could screen for personality disorders in general and for severe personality disturbance (SPD) in particular, at the time when patients seek treatment for a state (mood or anxiety) disorder. The SCL-90-R was administered to 112 consecutive outpatients with various mood and anxiety disorders. The personality severity index (PSI) score, defined as the mean value of the scores on the SCL-90-R subscales of interpersonal sensitivity, hostility, and paranoid ideation, was compared with the current symptom index (CSI) score, defined as the mean value of the scores on the remaining six SCL-90-R subscales. A positive screen was considered if PSI > CSI. SPD was defined as the presence of any DSM-III-R Cluster A and/or Cluster B personality disorder. The accuracy of the screen was verified by means of the Structured Clinical Interview for DSM-III-R Personality Disorders. The sensitivity of the PSI > CSI criterion to screen for SPD was 89.4%, while its sensitivity to screen for any DSM-III-R personality disorder was 72.9%. The SCL-90-R subscales that contributed the most to the screening discriminability of this SCL-90-R-derived screening measure were hostility, paranoid ideation, somatization, and obsessive-compulsive behavior. The SCL-90-R may be used to screen for SPD in routine work with outpatients with mood and anxiety disorders, but the results of the screening need to be verified because of the possibility of false negatives and false positives, although that possibility is apparently low. These findings may have important prognostic and treatment implications.     

Development of a spiritual screening tool for children and adolescents

A chaplain's ability to provide care where it is most needed depends upon some method of pastoral triage. Screening for spiritual needs of children and adolescents has been a largely neglected area. A Delphi panel developed elements to be included in a tool to screen 10-18 year olds' spiritual needs and resources. The Delphi panelists were informed of survey results of school-aged children and adolescents' opinions on spiritual issues important to them if they were hospitalized. A case study of the tool's use was conducted with a convenient sample of children and adolescents. Subsequent pilot use of the tool by five pediatric chaplains demonstrated the tool's utility in identifying patients' spiritual issues, ability to serve as a springboard to deeper discussion, and as a basis for initiating discussion of spiritual concerns with other disciplines on the healthcare team. Feedback indicates the potential clinical usefulness of this tool for hospitalized children and adolescents.     

Test anxiety in Indian children: a cross-cultural perspective

The present investigation examined test anxiety in Indian children from a cross-cultural perspective. Test anxiety has been studied extensively in western countries but much less so in eastern countries. Furthermore, the cross-cultural research conducted in eastern countries possesses significant limitations and continues to possess a western bias. The present research attempted to advance cross-cultural research on test anxiety by adopting Berry's imposed etic-emic-derived etic methodology. Participants included 231 schoolchildren. Qualitative data were collected to examine culture-specific variables (emic considerations) using structured focus groups and open-ended questions. Next, quantitative data were collected using translated and adapted versions of Spielberger's Test Anxiety Inventory and the FRIEDBEN Test Anxiety Scale. Qualitative data indicated culture-specific elements of test anxiety in Indian youth, including the high stakes associated with exam performance and future schooling as well as the role of somatization and social derogation in the phenomenological experience of test anxiety. Although quantitative findings failed to confirm the importance of high-stakes environments on test anxiety, the importance of somatization and social derogation was substantiated. Ongoing desensitization to test anxiety and enhanced coping responses were proposed as possible explanations for the obtained relations.     

The Eating Attitudes Test: development of an adapted language form for children

The purpose of this study was to determine the comparability of scores generated by two forms of the Eating Attitudes Test, the original form for adults and an adapted language form for children. Analysis of data indicated that the adapted language form of the test can be used effectively.
