Family dysfunction, parental attachment, and career search self-efficacy among community college students.

The relationship between family dysfunction, parental attachment, and career search self-efficacy was examined using a sample of 220 community college students. For the total sample, attachment to mother and father, and degree of family dysfunction combined to account for 14% of the variance in career search self-efficacy. Data were analyzed separately for men and women, which yielded results consistent with the literature. For women, attachment to mother and degree of family dysfunction combined to account for 17% of the variance in career search self-efficacy. For men, attachment to mother was the only significant predictor and accounted for 9% of the variance in career search self-efficacy. Implications for research and practice are described.

The Effects of Age and Dementia of the Alzheimer's Type on Phonological False Memories.

The authors conducted 3 experiments that examined the effects of age and dementia of the Alzheimer's type (DAT) on phonological false memories. In addition, the study was designed to investigate the role of inhibitory control in mediating phonological false memories. In Experiment 1, both young-old and old-old participants exhibited increased susceptibility to false remembering, compared with young adults. In Experiment 2, auditory Stroop interference was used as an index of inhibitory abilities and was found to account for a significant percentage of the variance in false recollection. Experiment 3 provided converging evidence for the importance of inhibitory control in phonological false memories by demonstrating that DAT patients are more susceptible to false recall and recognition than healthy older adults. The results are discussed within the inhibitory deficit framework of cognitive aging. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

An examination of the relationship between general life stress, racism-related stress, and psychological health among black men.

This study explored the relationship among general life stress, racism-related stress, and psychological health in a sample of 220 Black men. Participants completed a personal data form, the Perceived Stress Scale (S. Cohen, T. Kamarck, & R. Mermelstein, 1983), a modified version of the Schedule of Racist Events (H. Landrine & E. A. Klonoff, 1996), and the Mental Health Inventory (C. T. Veit & J. E. Ware, 1983). Results of hierarchical regressions indicated that when general stress was controlled, racism-related stress predicted an additional 4% of variance in psychological distress for working class men and an additional 7% for middle-upper class men. Racism-related stress also predicted an additional 5% of variance in psychological well-being for middle-upper class men; however, it was not predictive of psychological well-being for working class men. Implications for counseling practice and future research are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Pulmonary hemodynamics in the obstructive sleep apnea syndrome. Results in 220 consecutive patients

We have investigated pulmonary hemodynamics in a large series of consecutive, unselected patients with obstructive sleep apnea syndrome (OSAS). The aims of this study were to evaluate the frequency of pulmonary artery hypertension (PH) in OSAS and to analyze, as far as possible, its mechanisms. Two hundred twenty patients were included on the basis of a polysomnographic diagnosis of OSAS (apnea+hypopnea index > 20). PH, defined by a resting mean pulmonary artery mean pressure (PAP) of at least 20 mm Hg, was observed in 37 of 220 patients (17%). Patients with PH differed from the others with regard to pulmonary volumes (vital capacity [VC], FEV1) and the FEV1/VC ratio that were significantly lower (p < 0.001); PaO2 (64.4 +/- 9.3 vs 74.7 +/- 10.1 mm Hg; p < 0.001); PaCO2 (43.8 +/- 5.4 vs 37.6 +/- 3.9 mm Hg; p < 0.001), apnea+hypopnea index (100 +/- 33 vs 74 +/- 32; p < 0.001), and mean nocturnal arterial oxygen saturation (SaO2) (88 +/- 6% vs 94 +/- 2%; p < 0.001). Patients with PH were also more overweight (p < 0.001). Multiple regression analysis showed that 50% of the variance of PAP could be predicted by an equation including PaCO2 (accounting for 32% of the variance), FEV1 (12%), airway resistance (4%), and mean nocturnal SaO2 (2%). In conclusion, PH is observed, in agreement with previous studies, in less than 20% of OSAS patients. PH is strongly linked to the presence of an obstructive (rather than restrictive) ventilatory pattern, hypoxemia, and hypercapnia, and is generally accounted for by an associated obstructive airways disease. In this regard, the severity of OSAS plays only a minor role.     

Strategic, method, and stylistic variance in the MMPI.

"Strategic variance arises in the assessment of an S's communality with respect to a normative group on a dimension defined by contrast with a criterion group. Method variance is due to the idiosyncratic nature of the total item pool in regard to the proportion of true and false keyings and the distribution of item popularity values. (Stylistic variance includes dispositions to agree (acquiescence) or disagree (cautiousness) with neutral statements, independently of item content." In these terms, relevant research with the MMPI is reviewed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Components of variance due to acquiescence and content in the F scale measure of authoritarianism.

"This paper presents a method for computing the amount of acquiescence response set variance and content variance in an opinion questionnaire of true false or agree-disagree format. The method is used to reanalyze the results of recently published investigations of acquiescence response set occurring in the California F Scale measure of authoritarianism. For raw data, the method uses scores on the scale as originally constituted as well as on scales of reversed items obtained from the same group of subjects."

The pairwise multiple comparison multiplicity problem: An alternative approach to familywise and comparison wise Type I error control.

When undertaking many tests of significance, researchers are faced with the problem of how best to control the probability of committing a Type I error. The familywise approach deals directly with multiplicity problems by setting a level of significance for an entire set of related hypotheses; the comparison approach ignores the issue by setting the rate of error on each individual hypothesis. A new formulation of control, the false discovery rate, does not provide control as stringent as that of the familywise rate, but concomitant with this relaxation in stringency is an increase in sensitivity to detect effects relative to the sensitivity of familywise control. Type I error and power rates for 4 relatively powerful and easily computed pairwise multiple comparison procedures were compared with the false discovery rate procedure for various 1-way layouts by use of test statistics that do not assume variance homogeneity.

Predicting relationship and life satisfaction from personality in nationally representative samples from three countries: The relative importance of actor, partner, and similarity effects.

Three very large, nationally representative samples of married couples were used to examine the relative importance of 3 types of personality effects on relationship and life satisfaction: actor effects, partner effects, and similarity effects. Using data sets from Australia (N = 5,278), the United Kingdom (N = 6,554), and Germany (N = 11,418) provided an opportunity to test whether effects replicated across samples. Actor effects accounted for approximately 6% of the variance in relationship satisfaction and between 10% and 15% of the variance in life satisfaction. Partner effects (which were largest for Agreeableness, Conscientiousness, and Emotional Stability) accounted for between 1% and 3% of the variance in relationship satisfaction and between 1% and 2% of the variance in life satisfaction. Couple similarity consistently explained less than .5% of the variance in life and relationship satisfaction after controlling for actor and partner effects.

Deconfounding the effects of dominance and social acceptance on self-esteem.

Three studies examined the independent effects of social acceptance and dominance on self-esteem. In Studies 1 and 2, participants received false feedback regarding their relative acceptance and dominance in a laboratory group, and state self-esteem was assessed. Results indicated that acceptance and dominance feedback had independent effects on self-esteem. Study 2 showed that these effects were not moderated by individual differences in participants' self-reported responsivity to being accepted versus dominant. In Study 3, participants completed multiple measures of perceived dominance, perceived acceptance, and trait self-esteem. Results showed that both perceived dominance and perceived acceptance accounted for unique variance in trait self-esteem, but that perceived acceptance consistently accounted for substantially more variance than perceived dominance. Also, trait self-esteem was related to the degree to which participants felt accepted by specific people in their lives, but not to the degree to which participants thought those individuals perceived them as dominant.

Generalized self-efficacy, self-esteem, and negative affect.

In order to help resolve the ongoing debate about the relationship between and the functions of self-esteem and generalized self-efficacy (GSE), the authors tested the hypotheses that GSE predicts future self-esteem and that self-esteem predicts unique incremental variance in future negative affect. Measures of these three constructs were administered to two samples of undergraduates (N = 160 and N = 75) twice over five-six weeks. Time 1 GSE accounted for significant variance in Time 2 self-esteem in both studies, 1.6% of the variance in Study 1 and 4.6% of the variance in Study 2, after controlling for Time 1 self-esteem. Time 1 self-esteem did not predict Time 2 GSE in either study. Self-esteem accounted for significant variance in negative affect in Study 1. Results suggest that GSE and self-esteem are distinct, that GSE may play a role in the development of self-esteem, and that self-esteem may help shape negative affect.

Depression as measured by the DSM-III and the Beck Depression Inventory in an unselected adult population.

The National Institute of Mental Health Diagnostic Interview Schedule (DIS) and Beck Depression Inventory (BDI) were administered to 298 volunteers (average age 37.9 yrs) to determine the relation between DSM-III diagnosis of depression derived from the DIS and BDI scores of Ss. Results show that DSM-III diagnoses of depression were not associated with specific ranges of scores on the BDI, due to the heterogeneous nature of the category of dysthymic disorder. Using a cutting point of 9/10, sensitivity was 100%, specificity 86%, the proportion of false negatives 0%, and of false positives 13.7%, respectively. Upward adjustment of the cutting point on the BDI to 21/22 for research purposes reduced false positives to 1.4% but increased false negatives correspondingly to 52.4%. Upward adjustment of the cutting point on the BDI to 18/19 for epidemiologic purposes yielded an unbiased estimate of the prevalence of depression diagnosed by the DSM-III.

Effect of background items on responses to personality inventory items.

3 questionnaires were constructed. 1 consisted of just items from the MMPI Social Introversion (Si) Scale. The 2nd had these items intermingled with items (from the MMPI L and K scales) which usually evoke a "true" response. The 3rd questionnaire had the Si items intermingled with items (from the F scale) which usually evoke a "false" response. There were 6 groups (45 Ss each), a male and female group for each form. The experimental hypothesis was that Ss would respond differentially to the Si items depending on the background items. Analysis of variance showed no significant effects associated with the different forms. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

An approach to general oncology: principles and procedures

53 patients clinically suspected of having a cerebellopontine angle (CPA) lesion were examined by computer tomography (CT) with 160 X 160 matrix EMI scanner. 17 cases (32%) had tumour positive CT, of which 12 were neurinomas and 1 meningioma. 1 CT suggestive of a CPA lesion was false positive and 1 unoperated case is probably a false negative CT. Three of the eleven verified neurinomas (27%) were of the medial type originating in the angle cistern. One neurinoma protruding 1 cm into the cistern showed no contrast enhancement. 2 CT scans (3.8%) were unsatisfactory due to movements and the large size of the head. CT is valuable for the investigation of CPA pathology and the diagnostic efficiency compares favourably to other neuroradiological procedures.     

LPS-stimulated SJL macrophages produce IL-12 and IL-18 that inhibit IgE production in vitro by induction of IFN-gamma production from CD3intIL-2R beta+ T cells

SJL mice are known for their poor IgE production upon helminth infection. In this study, we have demonstrated that SJL standard B cells (85% IgM+ or B220+), prepared by complement-mediated T cell lysis, failed to proliferate and to produce IgE and IgG1 in response to LPS plus IL-4 in vitro. This diminished IgE production was restored by anti-IL-12 and enhanced by additional treatment with anti-IL-18, suggesting active suppression by the cells that produce IL-12 and IL-18. Indeed, SJL standard B cells were contaminated with Mac-1+ cells. Therefore, we removed macrophages by passing standard B cells through a Sephadex G-10 column (G10). Resultant cells (95% IgM+), designated as G10-B cells, responded to LPS and IL-4 by their proliferation and differentiation. G-10 treatment markedly diminished the proportion of B220- cells and Mac-1+ cells in SJL standard B cells. Furthermore, addition of SJL B220- cells dose dependently and MHC independently inhibited LPS plus IL-4-induced B cell growth and IgE production in SJL and BALB/c B cells. B220- cells in SJL standard B cells contained Mac-1+ cells (51%) and Fas ligand+ CD4-CD8- double-negative CD3intIL-2R beta+ T cells (26%). Thus, IL-12 and IL-18 produced by LPS-stimulated Mac-1+ cells stimulate this unique subpopulation of T cells to produce IFN-gamma, which in combination with Fas ligand, inhibits IgE production from the B cells. Our present results indicate that Mac-1+ cells and double-negative CD3intIL-2R beta+ T cells, uniquely abundant in the spleens of SJL mice, inhibit IgE production, indicating their new role in IgE response.     

Enhancing target variance in personality impressions: Highlighting the person in person perception.

D. A. Kenny (1994) estimated the components of personality rating variance to be 15, 20, and 20% for target, rater, and relationship, respectively. To enhance trait variance and minimize rater variance, we designed a series of studies of personality perception in discussion groups (N?=?79, 58, and 59). After completing a Big Five questionnaire, participants met 7 times in small groups. After Meetings 1 and 7, group members rated each other. By applying the Social Relations Model (D. A. Kenny and L. La Voie, 1984) to each Big Five dimension at each point in time, we were able to evaluate 6 rating effects as well as rating validity. Among the findings were that (a) target variance was the largest component (almost 30%), whereas rater variance was small (less than 11%); (b) rating validity improved significantly with acquaintance, although target variance did not; and (c) no reciprocity was found, but projection was significant for Agreeableness.

Social interaction skills and theory of mind in young children.

Two studies explored relations between peer social skills and theory of mind in young children. In Study 1, a global teacher rating of social skills with peers, performance on a traditional false-belief task, a standardized assessment of auditory language comprehension, and a time sampling of amount of speech with peers were obtained. Positive, but moderate, zero-order correlations were observed between the false-belief measure and social skills, and false belief accounted for a significant amount of additional variance in social skills after covarying age and the 2 measures of language. Study 2 replicated the findings of Study 1 by using a larger sample and a standardized teacher questionnaire. The results are discussed with regard to the critical role of a mentalistic theory of behavior for human social interactions. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

An assessment of the reproducibility of combined glottography in a clinical setting

Although combined glottography has potential as a clinical tool, it has had limited use in the monitoring of laryngeal function before and after treatment. There is no data about the standardization nor reproducibility of the procedure. An indication of the reproducibility of combined glottography is paramount if changes in laryngeal function are to be measured accurately. Using a standardized technique, two complimentary studies examined the reproducibility of combined glottography within one sitting (Study 1) and over time (Study 2). The components of variance were analysed (ANOVA). In Study 1 the variance under controlled conditions for Open Quotient (OQ) and Speed Quotient (SQ) was only 13% and 18% respectively of the total, whilst in Study 2 the variance over time for OQ and SQ was 55% and 58% respectively. Under controlled conditions combined glottography is a reproducible technique.     

Influence of Nonplastic Fines on Shear Wave Velocity-Based Assessment of Liquefaction

Many false positives (no liquefaction detected when the normalized shear wave velocity-cyclic stress ratio (Vs1-CSR) combination indicated that it should have been) are observed in the database used in the simplified liquefaction assessment procedure based on shear wave velocity. Two possible reasons for false positives are the presence of a thick surface layer of nonliquefiable soil and the effects of fines on cyclic shear resistance (CRR) and Vs1. About 67% of the false positives that could not have been caused by an overlying thick surface layer are associated with silty sands with less than 35% fines. The effects of fines on the liquefaction resistance of silty sands and on the shear wave velocity are analyzed. Theoretical CRRfield?versus?Vs1 curves for silty sands containing 0 to 15% nonplastic fines are established. They show that the theoretical CRR-Vs1 correlations for silty sands with 5 to 15% nonplastic fines are all located to the far left of the semi-empirical curves that separate liquefaction from no-liquefaction zones in the simplified liquefaction potential assessment procedures. The results suggest the currently used shear wave velocity-based liquefaction potential curves may be overly conservative when applied to sands containing nonplastic fines.
