To investigate further the basic item-factor structure of the Junior Eysenck Personality Inventory, a principal components analysis and varimax rotation were conducted on responses of 866 children (aged 7 to 16 yr.) from schools in the Rotorua area of New Zealand. Ten factors were extracted of which 7 were interpretable. These were named: Factor 1. Neuroticism I (Neurotic affect), Factor 2. Extraversion I (Impulsivity), Factor 3. Lie Scale, Factor 4. Extraversion II (Introversion), Factor 5. Extraversion III (Jocularity), Factor 6. Extraversion IV (Sociability), Factor 8. Neuroticism II (Neurotic ideation).

Depression Scales

The Zemore Depression-Proneness Rating Scale was administered to 208 university students. A principal components analysis with varimax rotation identified three factors representing Negative Self-attitude, Performance Difficulty, and Lack of Appetite. Some similarity between the present factors and those of the Beck Depression Inventory was discussed. Because the scale overemphasizes cognitive components, attention to items on the somatic aspects of depression was suggested. However, it should be noted that depression-proneness appears to be the feature of Zemore's scale that sets it apart from other depression scales.

Questionnaire Measures

The reliability and factor structure of the Spanish version of the Object-Spatial Imagery and Verbal Questionnaire (OSIVQ) were assessed in a sample of 213 Spanish university graduates. The questionnaire measures three types of processing preferences (verbal, object imagery, and spatial imagery). Principal components analysis with varimax rotation identified three factors, corresponding to the three scales proposed in the original version, explaining 33.1% of the overall variance. Cronbach's alphas were .72, .77, and .81 for the verbal, object imagery, and spatial imagery scales, respectively.

Sensation Seeking Scale

A principal components analysis of Sensation-seeking Scale IV ( n = 156 undergraduates) followed by a varimax rotation provided some support to the factorial validity of some of Zuckerman's subscales. It is suggested that the dimensions of sensation seeking were arbitrarily limited in earlier work on the problem.

Analysis of data from 255 U.S. pharmacists provides support for the consistency and validity of this short-form conservatism scale. The scale returned a coefficient alpha of 0.82, and principal components analysis yielded a strong general conservatism factor. Varimax rotation produced five factors consistent with the factor structure of the original Conservatism Scale.

The present study was designed to determine the number and nature of factors involved in Rotter's I-E Scale and to examine the question of the multidimensionality of the scale. Subjects were 329 college undergraduates. Principal components analysis was performed on the 23 pertinent items of the scale, followed by Varimax rotation. Multiple criteria indicated a 10-factor solution which accounted for 61% of the total variance. The first two factors were strongly similar to those reported previously. Results support Rotter's (1975) contention that subclasses within the scale will vary from sample to sample.

We present the factor structure of the General Health Questionnaire-60 as derived from a population of 2115 Army soldiers. An eight-factor principal components analysis provided the most clinically relevant solution and explained 58.0% of the variance. We distinguished two types of depressive symptomatology, suggesting the questionnaire may be useful in differentiating shame-ridden dysphoria from anergic disinterest.

Components Analysis

Factor analysis was performed on the Beck Depression Inventory with a university sample to examine its potential multidimensionality. A principal components analysis with an oblimin and varimax rotation produced a two-factor solution. These factors were labeled Cognitive–Affective and Physiological and accounted for approximately 39% of the common variance. This finding is consistent with multidimensionality of the inventory and with a similar study of college students. The commonalities of the two studies suggest the reliability (internal consistency) of the Cognitive-Affective and Physiological constructs among “minimally” depressed university samples.

To investigate the construct validly of a section of a high stakes test, an exploratory factor analysis using principal components analysis was employed. The rotation used was varimax with the suppression level of .30. Eleven factors were extracted out of 35 reading comprehension items. The fact that these factors emerged speak to the construct validity of the test. However the problem of over-factoring was obvious. This may be attributable to different paradigms of testing on which the items were based. In other words, the test constructer opted for passages from TOEFL, FCE and IELTS books with much alteration.

Σκοπός της παρούσας έρευνας ήταν η διερεύνηση των παραγόντων που επηρεάζουν το ανταγωνιστικό εξαγωγικό πλεονέκτημα και τα κίνητρα διεθνοποίησης των ελληνικών επιχειρήσεων παραγωγής γιαουρτιού. Οι παράγοντες αυτοί που σχετίζονται με το ανταγωνιστικό εξαγωγικό πλεονέκτημα αναφέρονται στους πόρους, τις ικανότητες και τα χαρακτηριστικά των επιχειρήσεων ενώ οι παράγοντες που αναφέρονται στα κίνητρα διεθνοποίησης σχετίζονται με το εξωτερικό περιβάλλον της επιχείρησης, τα εμπόδια των εξαγωγών, το ανταγωνιστικό εξαγωγικό πλεονέκτημα και του πόρους της επιχείρησης Για την διερεύνηση των συγκεκριμένων παραγόντων πραγματοποιήθηκε ποσοτική έρευνα σε 137 ελληνικές επιχειρήσεις παραγωγής γιαουρτιού καταγράφοντας την αντίληψη τους για τα παραπάνω ζητήματα. Η έρευνα στηρίχθηκε σε πρωτογενή δεδομένα που συγκεντρώθηκαν με ηλεκτρονική αποστολή ερωτηματολογίου σε υψηλόβαθμα στελέχη των επιχειρήσεων. Το χρονικό διάστημα διεξαγωγής της έρευνας ήταν από το Απρίλιο έως τον Αύγουστο του 2015. Μετά τη συλλογή των ερωτηματολογίων, πραγματοποιήθηκε ο έλεγχος εγκυρότητας και αξιοπιστίας των ερωτήσεων του ερωτηματολογίου. Εφαρμόστηκε αρχικά η διερευνητική παραγοντική ανάλυση (Factor Analysis-EFA) με τη μέθοδο εξαγωγής των παραγόντων σε κύριες συνιστώσες (Principal Components Analysis-PCA) και μέθοδο περιστροφής των αξόνων τη Varimax Rotation. Στη συνέχεια εφαρμόστηκε η επιβεβαιωτική παραγοντική ανάλυση (Confirmatory Factor Analysis-CFA) μέσω του στατιστικού προγράμματος SPSS Amos 24.0. Η εφαρμογή των συγκεκριμένων μεθόδων έδωσε ικανοποιητικά αποτελέσματα σχετικά με την εγκυρότητα των παραγόντων των ερωτήσεων που περιείχε το ερωτηματολόγιο. Η αλληλεπίδραση των παραγόντων και το αποτέλεσμα που έχουν στο ανταγωνιστικό εξαγωγικό πλεονέκτημα και στα κίνητρα διεθνοποίησης εκτιμήθηκαν με την εφαρμογή της μεθόδου ανάλυσης διαδρομών (Path Analysis). Τα αποτελέσματα της διατριβής και το υπόδειγμα διαδρομών του εξαγωγικού πλεονεκτήματος καταδεικνύουν ότι οι πόροι και ικανότητες τις επιχείρησης είναι σημαντικοί παράγοντες που οδηγούν τις ελληνικές επιχειρήσεις σε εξαγωγικό ανταγωνιστικό πλεονέκτημα σε αντίθεση με τα χαρακτηριστικά της επιχείρησης στα οποία δεν εντοπίστηκε κάποια σημαντική επιρροή. Επίσης, τα αποτελέσματα του υποδείγματος διαδρομών που αφορούσε τα κίνητρα διεθνοποίησης των ελληνικών επιχειρήσεων παραγωγής γιαουρτιού καταδεικνύουν το εξωτερικό περιβάλλον, τα εμπόδια εξαγωγών, ανταγωνιστικό εξαγωγικό πλεονέκτημα και τους πόρους της επιχείρησης από τους σημαντικότερους παράγοντες που επηρεάζουν τα κίνητρα των ελληνικών επιχειρήσεων σε εξαγωγική δράση.

The present study sought to assess the factor invariance of Jones and Crandall's short form measure of self-actualization on a sample of 213 black undergraduates. A principal components analysis followed by a varimax rotation yielded five factors, four of which were interpretable. The obtained structure essentially replicated that of Jones and Crandall; however, there were differences that indicate the test cannot be assumed to be invariant across ethnic groups.
