Some thoughts on the "culture-fairness" of personality inventories.

Issues attending the use of personality inventories in cultures other than the one in which it was sired were discussed. To demonstrate some of these points data were presented that indicated differential understandability of certain trait names between two cultures as similar as Canada and the U.S. The need for a research-based program prior to the adoption of non-Canadian tests into Canadian settings was stressed. The documented American-Canadian differences were also discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Correlational structure of the MCMI-III personality disorder scales and comparisons with other data sets

We examine the correlational structure of the personality disorder (PD) scales from the MCMI-III (Millon, 1994) among 614 college students. The correlation matrix from our nonclinical sample was highly similar to the clinical sample matrices reported by Millon (1994). Further analyses revealed that the correlation matrices from a variety of MCMI data sets are generally similar to one another, but are only moderately similar to PD correlation matrices based on other assessment techniques. PD correlation matrices based on different assessment techniques are generally not very similar to one another. Two-, 3-, and 4-factor solutions for the MCMI-III PD scales are reported and provide a framework for integrating apparently conflicting findings from previous work. The 4-factor solution was most meaningful and was consistent with the 5-factor model of PD.     

The significance of time spent in answering personality inventories.

Rankings of electronic sales engineers with respect to success in sales were correlated with ratios of time spent on inventories over time spent on all tests. The highest correlations were sales inventories as related to total time on all tests. The hypothesis that more time would be spent on sales personality and sales interest inventories was supported.

Assessment of obsessive-compulsive symptom dimensions: Development and evaluation of the Dimensional Obsessive-Compulsive Scale.

Although several measures of obsessive-compulsive (OC) symptoms exist, most are limited in that they are not consistent with the most recent empirical findings on the nature and dimensional structure of obsessions and compulsions. In the present research, the authors developed and evaluated a measure called the Dimensional Obsessive-Compulsive Scale (DOCS) to address limitations of existing OC symptom measures. The DOCS is a 20-item measure that assesses the four dimensions of OC symptoms most reliably replicated in previous structural research. Factorial validity of the DOCS was supported by exploratory and confirmatory factor analyses of 3 samples, including individuals with OC disorder, those with other anxiety disorders, and nonclinical individuals. Scores on the DOCS displayed good performance on indices of reliability and validity, as well as sensitivity to treatment and diagnostic sensitivity, and hold promise as a measure of OC symptoms in clinical and research settings.

PCR-restriction fragment length polymorphism (RFLP) analyses reveal both extensive clonality and local genetic differences in Candida albicans

Using a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method to obtain genotypes for the diploid pathogenic yeast, Candida albicans, we analysed 204 C. albicans isolates from three populations of the Duke University community: two from clinical sources [one from patients infected with human immunodeficiency virus (HIV) and the other from patients without HIV infection], and the third from healthy student volunteers. The results indicated: (i) extensive evidence for clonality within and between populations of C. albicans; and (ii) greater genotypic and gene diversities in the nonclinical population than those derived from clinical specimens, regardless of HIV status. The two clinical populations were genetically more similar to each other than either was to the population consisting of isolates from healthy people. Within each population sample there was a general lack of heterozygotes, and random associations of alleles within and between loci were found in less than 50% of the loci or pairs of loci. These findings were consistent between the two sets of samples analysed: those including all isolates and those including only clone-corrected isolates. Possible mechanisms are presented to explain the observed patterns of genetic variation within and between C. albicans populations.     

Construction and psychometric characteristics of two self-report questionnaires for the assessment of fear of flying.

This article presents the development of and data on the dimensional structure, reliability, and validity of 2 new inventories for assessing different aspects of fear of flying: the Flight Anxiety Situations questionnaire (FAS), which assesses anxiety related to flying experienced in different situations, and the Flight Anxiety Modality questionnaire (FAM), which measures symptom modalities in which anxiety in flight situations is expressed. Two initial questionnaires were constructed from multiple sources. Factor analytic studies were conducted to assess their internal structure, and the final versions were examined in a sample of 746 patients who experienced fear of flying. A principal-components analysis investigated the optimal dimensional structure in 2 randomly created subsamples. A 3-factor solution for the FAS and a 2-factor solution for the FAM were revealed. The internal consistency and test-retest reliability were good to excellent. Moderately strong correlations between the subscales suggest sufficient factorial specificity and convergent validity. The subscales were sensitive to change. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Types of dissociation and dissociative types: A taxometric analysis of dissociative experiences.

This article examined evidence for dimensional and typological models of dissociation. The authors reviewed previous research with the Dissociative Experiences Scale (DES; E. B. Bernstein-Carlson & F. W. Putnam; see record 1987-14407-001) and note that this scale, like other dissociation questionnaires, was developed to measure that so called dissociative continuum. Next, recently developed taxometric methods for distinguishing typological from dimensional constructs are described and applied to DES item-response data from 228 adults with diagnosed multiple personality disorder and 228 normal controls. The taxometric findings empirically justify the distinction between two types of dissociative experiences. Nonpathological dissociative experiences are manifestations of a dissociative trait, whereas pathological dissociative experiences are manifestations of a latent class variable. The taxometric findings also indicate that there are two types of dissociators. Individuals in the pathological dissociative class (taxon) can be identified with a brief, 8-item questionnaire called the DES-T. Scores on the DES-T and DES are compared in 11 clinical and nonclinical samples. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

No more than skin deep: Ethnic and racial similarity in developmental process.

Many studies adduce evidence of ethnic or racial dissimilarities in developmental outcomes (e.g., delinquency and achievement). Many researchers fail to distinguish between group average levels and developmental processes (correlations). Evidence is reviewed that developmental processes are nearly identical for US Black, Hispanic, White, and Asian ethnic and racial groups. Using diverse and representative data sources, covariance matrices were computed for these ethnic groups and then compared by using a LISREL goodness-of-fit test. Not only were these matrices nearly identical but they also were no less alike than covariance matrices computed from random halves within 1 ethnic or racial group. This article documents the importance of accepting ethnic and racial similarity of developmental processes. Thus, group average level differences may result from different levels of developmental antecedents working through common developmental pathways.

Use and abuse of the children's depression inventory.

This study investigated current uses of the Children's Depression Inventory (CDI), a frequently cited self-report measure for children's depressive symptomatology. Recently published studies of "childhood depression" were reviewed: Half of them used the CDI. Of these studies, 68% did not use a clinical or structured interview to determine diagnostic status. When the CDI was used alone to assess depressive symptoms, 44% of studies referred to high CDI scorers as "depressed" without providing a clear cautionary statement (i.e., either stating that the CDI cannot be used to diagnose depression or clarifying limitations regarding generalization of findings from a nonclinical to a clinical sample). These results are similar to those previously published regarding the Beck Depression Inventory, and they suggest a need for caution in the administration and interpretation of results from self-report inventories for children's depressive symptoms.

Factor structure of the Basic Interest Scales by gender across time.

Studied gender differences in the factor structure of the Basic Interest Scales (BISs) across time. Nine correlation matrices, previously published in support of the BISs on the Strong Vocational Interest Blank–Strong-Campbell Interest Inventory, were factor analyzed. Results describe a clear factor structure for the Basic Interest Scales. However, scale loadings did not support General Occupational Theme classifications of BISs. Similarities between men and women were observed in extracted factors and BISs with low communality estimates. Gender differences were found for between-factor correlations. A relatively stable factor structure was traced over time and was found to exist prior to the employment of women in traditionally restricted male occupations. Implications for counselors are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The relation of childhood abuse and early parenting experiences to current marital quality in a nonclinical sample

This study examines the relation between adults' reports of the nature of the early parenting they received, including abuse, and the quality of their marital relationship. This community sample of 159 married women and men experienced relatively low levels of abuse. The regression analyses indicated that for women verbal abuse in childhood was predictive of marital conflict, and the caring parenting they experienced predicted the depth of their marital relationship. For men, the abuse variables did not predict any dimension of their current marital relationship. Of the parenting variables, overprotection was significantly predictive of conflict in their marriage. No demographic variable--income, education, and number of siblings--predicted any dimension of marital quality for either men or women. Given the skew of the abuse data for this nonclinical sample, log transformations were performed on the data and the regression analyses were reported. One change was noted: that for men, physical abuse and overprotection were equally predictive of marital conflict. The results suggest that abuse and early parent experiences are predictive of marital functioning in a nonclinical sample, but that differences exist in the pattern for men and women.     

Voluntary facial expression of emotion: Comparing congenitally blind with normally sighted encoders.

The ability of congenitally blind persons to produce voluntarily facial expressions of a number of emotions was compared with that of normally sighted individuals using both objective facial measurement and observer recognition. Results revealed that there were almost no significant differences between blind and sighted participants with respect to the number and type of facial action units produced. The portrayals of the blind participants were significantly more poorly recognized by observers than were those of the sighted participants (except for happiness). Correspondence analyses of the data showed differences between sighted and blind participants in the dimensional structure of the expressions (as based on the similarity among emotions with respect to both objective measurement and judgments). Overall, the data relativize earlier conclusions on the facial expression of blind as compared with sighted persons and suggest specific hypotheses and procedures for further work in this area.

Contrasting population structure from nuclear intron sequences and mtDNA of humpback whales

Powerful analyses of population structure require information from multiple genetic loci. To help develop a molecular toolbox for obtaining this information, we have designed universal oligonucleotide primers that span conserved intron-exon junctions in a wide variety of animal phyla. We test the utility of exon-primed, intron-crossing amplifications by analyzing the variability of actin intron sequences from humpback, blue, and bowhead whales and comparing the results with mitochondrial DNA (mtDNA) haplotype data. Humpback actin introns fall into two major clades that exist in different frequencies in different oceanic populations. It is surprising that Hawaii and California populations, which are very distinct in mtDNAs, are similar in actin intron alleles. This discrepancy between mtDNA and nuclear DNA results may be due either to differences in genetic drift in mitochondrial and nuclear genes or to preferential movement of males, which do not transmit mtDNA to offspring, between separate breeding grounds. Opposing mtDNA and nuclear DNA results can help clarify otherwise hidden patterns of structure in natural populations.     

Effectiveness of correlation analysis in identifying protein residues undergoing correlated evolution

Various methods for detecting correlation between sites were evaluated by ascertaining their ability to discriminate positively correlated sites from background correlation at randomly evolved sites. A model for generating pairwise correlations of different degrees is also described. An assortment of physicochemical vectors and similarity and difference matrices were used to discriminate correlated change. There was little difference in effectiveness between the different matrices, but there were significant differences between the matrices and the physicochemical vectors. It is shown that all methods investigated exhibit significant inability to screen out background correlation, particularly in the presence of phylogenetic relatedness between the sequences. Methods using the matrices are unable to distinguish positively correlated from negatively correlated, or compensatory, replacements.     

An overview of depression in the elderly: a US perspective

Surnames are the result of historic and cultural processes which give information about the ethnic composition and genetic structure of populations. Based on the use of isolation and sedentarisness estimators, obtained from surnames frequency and distribution, the population dynamics of highland communities located at the Province of Jujuy (Northwest of Argentina), situated in two ecologically different regions, was analysed. Surnames were obtained from register of electors (1982) and they correspond to 67 villages of Quebrada of Humahuaca and Puna Juje?a. The surnames were analysed exactly as they were registered (NM = Non-merged) and merged according to their spelling and or similarity in pronunciation (M = Merged). The following estimators were used: 1) percentage of the population covered by unique surnames; 2) percentage of the population covered by the most frequent surnames; 3) ratio between number of individuals and number of surnames. Inter-population differences were detected by means of non-parametric tests. It was observed that, in general, there are no statistically significant differences between NM and M data and among the towns in Quebrada de Humahuaca and Puna, but there were differences according to whether they were located on or away from the main road between regions. These results were compared with those of other populations and we conclude that the simultaneous use of the 4 estimators, to characterize the isolation or sedentarisness of vast population groups, show highly consistent results.     

Subjectively interpreted shape dimensions as privileged and orthogonal axes in mental shape space.

The shape of an object is fundamental in object recognition but it is still an open issue to what extent shape differences are perceived analytically (i.e., by the dimensional structure of the shapes) or holistically (i.e., by the overall similarity of the shapes). The dimensional structure of a stimulus is available in a primary stage of processing for separable dimensions, although it can also be derived cognitively from a perceived stimulus consisting of integral dimensions. Contrary to most experimental paradigms, the present study asked participants explicitly to analyze shapes according to two dimensions. The dimensions of interest were aspect ratio and medial axis curvature, and a new procedure was used to measure the participants' interpretation of both dimensions (Part I, Experiment 1). The subjectively interpreted shape dimensions showed specific characteristics supporting the conclusion that they also constitute perceptual dimensions with objective behavioral characteristics (Part II): (1) the dimensions did not correlate in overall similarity measures (Experiment 2), (2) they were more separable in a speeded categorization task (Experiment 3), and (3) they were invariant across different complex 2-D shapes (Experiment 4). The implications of these findings for shape-based object processing are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)

Erratum to Searleman.

Reports an error in the article "A Review of Right Hemisphere Linguistic Capabilities" by Alan Searleman (Psychological Bulletin, 1977, Vol. 84, No. 3, pp. S03-S28). It is stated that Kohn and Dennis (1974) are convinced of a complete transfer of speech and language to the right hemisphere in left-hemispherectomized infantile hemiplegics. This claim is erroneous in that it overstates the degree of transfer reported by Kohn and Dennis. (The following abstract originally appeared in record 1978-00199-001) Observations made upon clinical populations during the last century have largely been responsible for supplanting the traditional view that the human cerebral hemispheres are structurally and functionally identical. Although today the left hemisphere is viewed as being responsible for most language functioning, in recent years evidence has accumulated that suggests that the right hemisphere also possesses linguistic skills. The present article surveys the available evidence for right hemisphere linguistic capabilities from both clinical and normal populations, including data from handedness, brain damage, hemispherectomy, and commissurotomy studies.
