PIAGET'S CONCEPT OF SPATIAL EGOCENTRISM: AREEVALUATION

Kielgast, Knud. Piaget's concept of egocentrism: A reevaluation. Scand. J. Psychol. , 1971, 12, 179–191. – It was found that the so-called egocentric reaction of identifying one's own perspective with the imagined perspective of some object seen from a different point of view could not be attributed to a fixation to one's own perspective but rather to a deficient perceptual differentiation between the visual world and the visual field. A comparison of verbal and non-verbal solutions was found to point to a near relationship between perception and imagination in this specific task.     

On use of student samples for scale construction

This research note responds to the question of whether a convenience sample of undergraduate students may be successfully utilized in concept development and in scale construction, and in what way the results are comparable to the findings of a representative national sample. The results of a Mokken analysis in both samples support the hypothesis that convenience samples have utility in concept development and in developing measures that can also be used in representative samples.     

Restrictions in means for suicide: an effective tool in preventing suicide: the Danish experience

Restriction of means for suicide is an important part of suicide preventive strategies in different countries. The effect on method-specific suicide rate and overall suicide rate of restrictions on availability of carbon monoxide, barbiturates, and dextropropoxyphene was examined. From 1970 to 2000, overall suicide mortality and method-specific suicide mortality in Denmark were compared with official information about availability of barbiturates and analgesics and carbon monoxide in vehicle exhaust and household gas. Restrictions on availability of household gas with carbon monoxide content and barbiturates was associated with a decline in the number of suicides and suicides by self-poisoning with these compounds after controlling for the effect of calender year. Restricted access occurred concomittantly with a 55 percent decrease in suicide rate.     

A two-wave cross-lagged study of business travel,work–family conflict,emotional exhaustion,and psychological health complaints

By using a two-wave panel design, the present study aimed at studying longitudinally the relation between business travel and work–family conflict (WFC) as well as the reciprocal relationships among WFC, emotional exhaustion, and psychological health complaints. The study was conducted in a large Norwegian oil and gas company (n = 1702), and the company’s business travel database was utilized to examine business travel. The results showed a positive cross-lagged relation between business travel and WFC. In addition, WFC predicted emotional exhaustion over time, whereas emotional exhaustion predicted psychological health complaints over time. Reversed influences also existed, supporting our hypotheses on reciprocal relations. The longitudinal design of the current study makes an important contribution to the research on business travel and employees’ psychological health.     

Scale development to measure attitudes toward unauthorized migration into a foreign country

This study reports on the development and cross-national utility of a Likert type scale measuring attitudes toward unauthorized migration into a foreign country in two samples from "migrant-sending" nations. In the first phase a pool of 86 attitude statements were administered to a sample of 505 undergraduate students in Bulgaria (22.5% male; M age = 23, SD = 4.8). Exploratory factor analysis resulted in six factors, and a reduction to 34 items. The results yielded an overall alpha of (0.92) and alpha for subscales ranging from 0.70 to 0.89. In the second phase the 34-item scale was administered in a survey of 180 undergraduates from Sofia University in Bulgaria (16.7% male, M age = 23, SD = 4.8), plus 150 undergraduates from Hanoi State University in Vietnam (14.7% male, M age = 19, SD = 1.8). Results yielded a 19-item scale with no gender differences, and satisfactory alpha coefficients for a Vietnamese and Bulgarian sample of 0.87 and 0.89 respectively. This scale, equally applicable in both samples, includes items that reflect salient topics of concept of attitudes towards unauthorized migration. An exploratory principal component analysis of the Bulgarian and Vietnamese version of the 19-item scale yielded three factors accounting for 54% and 47% of the variance respectively. A procrustes analysis indicates high conceptual equivalence in the two samples for factor 1 and 2, and moderate for factor 3. This study lends support to the idea that despite different cultural meanings there is a common meaning space in culturally diverse societies.     

Attitudes toward sex-roles: Traditional or egalitarian?

This article reports on the development of a Likert-type scale measuring attitudes toward egalitarian-traditional sex roles. A total of 484 undergraduates participated in six phases of the study. An item analysis study yielded 20 items with part-whole correlations <.48. The corrected split-half reliability coefficient is .91 (p.001). Five other phases of research show promising concurrent and construct validity. In particular, traditional attitudes are related to rigidity as measured by authoritarian, religious, same-sex touching, rape acceptance, divorce, and conservative attitudes. Overall, a varimax rotated factor analysis revealed one major factor accounting for 84.6% of the variance. Further, females were shown to have higher levels of egalitarian attitudes as compared to males.     

Attitudes toward illegal immigration: a cross-national methodological comparison

This research is an examination of the generalizability of a Likert-type scale originally devised to measure attitudes toward illegal immigrants (IA) in the United States. The current authors administered this scale across 4 national samples using several methodological procedures. Undergraduate students (631) responded to the IA scale (R. Ommundsen & K. S. Larsen, 1997) at the University of Oslo, Oregon State University, the University of Copenhagen, and Vrije University of Amsterdam. The authors' main purpose was to evaluate the adequacy of the 20-item IA scale by examining possible problems with method and translation. A translation study carried out with the Danish, Norwegian, and Dutch samples (N = 299) showed that the various national versions were fairly accurate and contained largely the same meanings. The use of procrustes analysis of the IA scale yielded 3 factors in all 4 national samples. The coefficient of congruence of these 3 orthogonally rotated factor matrices, with the U.S. factor matrix as target, varied from .80 to .95, supporting the cross-national robustness of the scale. In the search for a more economical cumulative scale, a Mokken analysis yielded a 5-item scale that represented the aforementioned 3 factors and was stable across national samples.     

Aggression-Altruism: A Scale and Some Data on Its Reliability and Validity

This article reports on the development of a scale designed to measure aggression. Using usual procedures for Thurstone scaling, a thirty-seven item Aggression Scale was created, Form A consisting of twenty items and Form B of seventeen. The test-retest reliability coefficient was .60. Results from three validity studies showed that aggression as measured by the Aggression Scale was related to perceived mild aggression training by fathers for males only, to nationalism, and to Machiavellianism.
