Internal consistency reliability of the tactual performance test trials

Internal consistency reliabilities were calculated for the Tactual Performance Test Preferred Hand (n=300), Nonpreferred H and (n=302), and Both Hands (n=314) trials, and Total Time. Reliabilities are reported for the total sample and three groups: normal, undiagnosed patients sent for assessment, and alcoholic persons. The reliability coefficients ranged from .59 to .90.     

Line bisection-based hemisphericity estimates of university students and professionals: evidence of sorting during higher education and career selection

Recently, hemisphericity has been assessed by six intercorrelated methods. Here, one of these, the "Best Hand Test," a two-hand line bisection-based biophysical method relatively independent of language, culture, or education, was applied to the measurement of hemisphericity distributions within large groups. Entering university students (n=402) enrolled in three lower division courses were chosen as a reference population. Each of these classes contained about 56% left brain-oriented individuals. In contrast, mean student left-brain distributions in four specialized, upper level courses (n=180), ranged from 35 to 68%, suggestive of hemisphericity sorting. Even more pronounced hemisphericity distribution differences were found within university representatives of 15 professions (n=421) and within professional subspecialists (n=45). For example, of biochemists (n=18), 83% were left brain-oriented, while among astronomers (n=21), only 29% were. These results are of intrinsic interest, and demonstrate the capability of the Best Hand Test to estimate hemisphericity in large groups.     

Maximizing split-half reliability estimates for projective techniques

Hand Test data from comparable sets of clinical samples were analyzed for reliability using the usual odd-even split and then also calculating all possible (126) split-half combinations. Maximum stable reliabilities were obtained which were substantially superior to the odd-even method. It was concluded that projective tests are probably more internally reliable than has heretofore been reported.     

Differences on the projective hand test among chronic pain patients reporting three different pain experiences

This study examined personality differences among individuals experiencing 3 different types of pain. The projective Hand Test was administered to 90 individuals who were seeking treatment at a pain clinic in an urban area of the southeast United States. These people were seeking treatment for either arthritis (n = 31), fibromyalgia (n = 29), or migraine headaches (n = 30). A 2 (gender) x 3 (pain group) x Age Group multivariate analysis of variance was conducted using the quantitative Hand Test scoring variables as dependent measures. Results indicated that individuals who were seeking treatment for migraine headaches had a higher production rate of responses involving exhibitionistic displays (EXH) than individuals in the other 2 groups. Individuals who were seeking treatment for fibromyalgia had a higher production rate of responses indicating fear and phobic concerns (FEAR) than individuals in the other 2 groups. Individuals who were seeking treatment for arthritis had a higher production rate of Active (ACT) responses than individuals in the other 2 groups. Possible causes and consequences of these effects are discussed.     

Exploring the structure of Zuckerman's Sensation Seeking Scale, Form V in a Spanish sample

The psychometric properties of the original version of the Sensation Seeking Scale (Form V) were analyzed in a sample of 1,006 Spanish university students. The total sample was randomly split into two halves. Exploratory factor analyses were conducted on the calibration sample (n=504), whereas confirmatory factor analysis procedures were performed on the validation sample (n=502). As previous studies have suggested, exploratory factor structure indicated that several items load on a different factor or have loadings lower than .30. Those problems were surpassed when the best five items per factor were factor analyzed again. The confirmatory factor analyses showed that a 4-factor simple structure model gave a clearly imperfect fit. A model of 20 items (5 items per factor) gave a better fit, although with similar problems regarding the low reliabilities of the Experience Seeking and Boredom Susceptibility subscales. The need for improvement of the four-factor structure is discussed.     

Repeated assessment of the Tower of Hanoi test: reliability and age effects

The purpose of this research was to analyze the effects of repeating an executive function test. Three versions of the Tower of Hanoi (TOH) test were repeated three times each, with test-retest intervals of 2 months. Two groups of children participated in the research (7.7 and 11.6 years, n = 22 and n = 28). Repeating the assessment improved the performance and decreased the total performance time in both of the groups. The older participants improved their performance faster than the younger ones. The reliability of all the scores, besides the error scores, seemed to be satisfactory after the first few assessments. The stability of the scores was maintained through all the assessments. The planning time did not explain the variations of the achieved score. The reasons for the initially low reliabilities are discussed, and modifications for the test administration and scoring are suggested.     

A Comparison of Three Rorschach Diagnostic Systems and Use of the Hand Test for Detecting Multiple Personality Disorder in Outpatients

Eleven individuals diagnosed with multiple personality disorder (MPD) on the basis of clinical observation by experienced therapists plus elevated scores on the Dissociative Experiences Scale (DES; Bernstein & Putnam. 1986) were administered the Rorschach Inkblo; Test and the Hand Test. Results from the sample (n = 11) and a matched control group (N = 22) were analyzed and discussed in accordance with previous Rorschach diagnostic systems. The Wagner Signs diagnosed 91% (n = 10) of the MPD cases in this outpatient sample, with no false positives. The Labott Signs were found to have no utility, and the Barach Signs, when they occurred, seemed to be diagnostic of MPD but yielded a high rate of false negatives. Hand Test results were analyzed and found to be possibly diagnostic of MPD. Tentative criteria were proposed for its use as an additional tool for diagnosing MPD.     

Psychopathology scale of the Hutt adaptation of the Bender-Gestalt Test: reliability.

The test-retest reliability of the Hutt Adaptation of the Bender-Gestalt test was explored with a population of 40 process schizophrenics over a two-week interval. The total Psychopathology Scale Score was found to have high retest reliability for both male and female patients (rho = .87 for males and .83 for females). Moreover the three major components for the Scale were found to have high reliability, and fairly high reliabilities were obtained for patients scoring high as well as low on the Scale. Interjudge reliability was also found to be very high (rho = .895), confirming previous studies in this respect. On these grounds, the Scale offers promise both for clinical and research purposes.     

Evidence of observer reliability for the Fagan Test of Infant Intelligence (FTII)

To obtain estimates of observer reliability, the Fagan Test of Infant Intelligence (FTII) apparatus was modified to allow the infants' performance to be videotaped. Based upon results of 25 infants scored once during time of testing and again 2 years later using the videotape version, interobserver and intraobserver reliabilities obtained for percent novelty preference (test rounds), total number of looks (familiarization and test rounds), and mean fixation (familiarization and test rounds) were mostly very high for each round (M r = .92, SD = .04). The videotaped infants' scores did not differ significantly from those of a comparable sample of infants who were tested using an unmodified apparatus.     

Tactual Performance Test: internal consistency reliability of the memory and location scores

Internal consistency reliabilities were computed for the Tactual Performance Test Memory and Location scores (N=602). After adjusting for unequal item difficulty, the reliabilities for Memory and Location were .69 and .79, respectively.     

Predictive Validity of the MMPI–2 Restructured Clinical (RC) Scales in a Batterers' Intervention Program

Summary: The test-retest reliability of the Hutt Adaptation of the Bender-Gestalt Test was explored with a population of 40 process schizophrenics over a two-week interval. The total Psychopathology Scale Score was found to have high retest reliability for both male and female patients (rho = .87 for males and .83 for females). Moreover the three major components of the Scale were found to have high reliability, and fairly high reliabilities were obtained for patients scoring high as well as low on the Scale. Interjudge reliability was also found to be very high (rho = .895), confirming previous studies in this respect. On these grounds, the Scale offers promise both for clinical and research purposes.     

Stability of cognitive vulnerabilities to depression: a short-term prospective multiwave study

The stability of 3 cognitive vulnerabilities--a negative cognitive style, dysfunctional attitudes, and rumination--as well as depressive symptoms as a benchmark were examined to investigate whether cognitive vulnerabilities are stable, enduring risks for depression. A sample of adolescents (6th-10th graders) completed measures of these 3 cognitive vulnerabilities and depressive symptoms every 5 weeks for 4 waves of data across 5 months. Mean-level and differential stability were examined for the sample overall and by age subgroups. A negative cognitive style exhibited mean-level stability, whereas rumination and dysfunctional attitudes showed some mean-level change. Absolute magnitudes of test-retest reliabilities were strong for depressive symptoms (mean r= .70), moderately high for a negative cognitive style (mean r= .52), and more modest for rumination (mean r= .28) and dysfunctional attitudes (mean r= .26). Structural equation modeling showed that primarily enduring processes, but not contextual forces, contributed to the patterning of these test-retest reliabilities over time for a negative cognitive style and dysfunctional attitudes, whereas both enduring and contextual dynamics appeared to underlie the stability for rumination. Theoretical and clinical implications of these findings are discussed.     

Asymmetry questionnaire outcomes correlate with several hemisphericity measures

The asymmetry questionnaire segregated subjects (n=143) into two groups. These were significantly correlated with similar groups separated, not only by three new biophysical hemisphericity protocols (Dichotic Deafness Test, Phased Mirror Tracing, Best Hand Test), but also by two preference-type measures (polarity questionnaire, preference questionnaire). Each of the 15 asymmetry questionnaire statements was significantly correlated with the outcomes of these five laterality measures. This is the third questionnaire whose outcomes correlate with those of the new biophysical measures of hemisphericity.     

Measurement of cathectic energies

An objective verbal cathexis test was developed in a series of experimental studies. The test was utilized to examine the validity of a personality theory which was defined within a biological frame of reference. A total of 293 normal subjects, 22 neurotics, and 16 habitual drunkards participated in the experiments. The results showed high reliabilities of the verbal test (r=0, 75-0.95), significant validity of the theory (confirmatory factor analysis, p>0.01, empirical validity, p<0.01), and that extreme cathexis for social objects was related to deviating adaptation in modern society.     

Exploring the hand test with medically ill children and adolescents

Pediatric psychologists use the tools of assessment to evaluate the psychological functioning of youth with chronic and acute medical illnesses. This study is an exploration of the use of a performance-based measure, the Hand Test (HT; Wagner, 1983), with pediatric medical patients. A sample of medical inpatients (n = 27) and psychiatric outpatients (n = 24) were administered the HT, a self-report measure, and a parent-report behavior rating scale. Results indicate that the psychiatric group scored higher than the medical group on HT Aggression, Withdrawal, and Pathological scores. The Aggression (d = 0.90) and Pathological (d = 0.80) variables were particularly robust in differentiating between groups, but the Crippled variable did not differ between groups. Hierarchical logistic regression demonstrated the incremental validity of the HT over behavior ratings alone in the classification of clinical groups. Analyses indicated that the HT can add important information in the differentiation of medically ill children from those with psychological disturbance.     

Psychometric properties of the Hooper Visual Organization Test

The psychometric properties of the Hooper Vsual Organization Test (VOT) have not been well investigated Here the authors present internal consistency and interrater reliability coefficients, and an item analysis, using data from a sample (N = 281) of "cognitively impaired" and "cognitively intact" patients, and patients with undetermined cognitive status. Coefficient alpha for the VOT total sample was .882. An item analysis found that 26 of the 30 items were good at discriminating among patients. Also, the interrater reliabilities for three raters (.992), two raters (.988), and one rater (.977) were excellent. Therefore, the judgmental scoring of the VOT does not interfere significantly with its clinical utility. The authors conclude that the VOT is a psychometrically sound test.     

Cohort differences in Hand Test performance: a time lagged analysis

In order to examine the impact of cultural differences (cohort and/or time of measurement) on the intrapsychic processes of older adults, two samples (1976, n = 102; 1986, n = 88) of older persons were compared with regard to their Hand Test (HT; Bricklin, Piotrowski, & Wagner, 1962; Wagner, 1983) performance. Relative to those studies investigating cultural effects in personality at the socioadaptational level (Neugarten, 1977), no research to date has examined this issue utilizing projective methods of assessment. Time-lagged analyses of HT scores of these two samples of elderly adults suggested that there appear to be clear age-related variance in HT performance for both content and derived HT variables. Age-related within-sample variability for most HT scores supported this interpretation. These findings are in contrast to those utilizing more standardized, nomothetic measures of personality functioning that suggest stability of personality in adulthood.

The children's depression adjective check lists (C-DACL) with emotionally disturbed adolescent boys

In this study of the reliability and validity of the Children's Depression Adjective Check Lists (C-DACL; Brewer & Lubin, 1987) with emotionally disturbed adolescent boys (N=50),data were collected on two occasions. Internal consistency (alpha) was .89 and .94 for form H and .89 and .95 for form I. Alternate form reliabilities were .86 and .95. Split-half reliabilities were .80 and .89 for form H and .68 and .86 for form I. Concurrent validity was determined by correlations between C-DACL and the Self-Rating Scale of Depressed Mood. Correlations were .65 and .80 for H and .54 and .80 for I. Data from the present study were tested against data from emotionally disturbed adolescent girls (Sokoloff & Lubin, 1983), with boys scoring significantly lower on both forms (H and I) of the C-DACL.     

Differences in asymmetric perception of facial expression in free-vision chimeric stimuli and reaction time

Two forms of a Chimeric Faces Free-Vision Task used to estimate cerebral asymmetry for perceiving facial expression were given to young male subjects, n = 60 in a first session and n = 40 in a retest session. Test-retest and split-half reliabilities were high. As expected from assumptions of right-hemisphere specialization for processing expression, faces with left-sided smiles were more frequently judged as looking happier than those with right-sided smiles in both forms. However, there were individual differences in direction and extent of bias, which were systematically related to reaction time, right visual field-biased subjects being slower. Differences in lateral bias as well as in reaction time are assumed to reflect individual patterns of hemispheric activation, whereas the average left bias in the present male group may reflect right-hemisphere specialization for processing of facial expression.
