Testdiagnostik von AVWS im Grundschulalter – eine faktorenanalytische Untersuchung

Zusammenfassung Hintergrund Unsere eklektische Testbatterie zur Diagnose von auditiven Verarbeitungs- und Wahrnehmungsstörungen (AVWS) wurde in mehreren Vorstudien eingesetzt. Nun sollte ihre Inhaltsstruktur faktorenanalytisch untersucht werden. Material und Methode Testergebnisse von 143 Kindern mit AVWS (96 Jungen) im mittleren Alter von 8,3 (SD 1,1) Jahren gingen in mehrere exploratorische Faktorenanalysen ein (EFA; Hauptkomponentenmethode). Unter Berücksichtigung der Ergebnisse diskriminanzanalytischer Vorstudien und der zugrunde liegenden Interkorrelationen wurde eine EFA mit 12 (von insgesamt 16) diagnostischen Tests gewählt. Ergebnisse Das Kaiser-Meyer-Olkin-Maß der Stichprobeneignung war mit 0,739 mittelmäßig bis tendenziell gut. Die Bestimmung der Faktorenzahl erfolgte anhand des Kaiser-Kriteriums (Eigenwert > 1) und sprach für 4 Faktoren, die 63,7 % Gesamtvarianz erklärten – bestätigt durch den Scree-Test. Laut Komponentenmatrix waren die Ladungen auf den unrotierten Faktoren vorwiegend auf dem ersten Faktor hoch, weswegen sich diese EFA nicht interpretieren ließ. Nach Promax-Rotation resultierte eine interpretierbare Faktorenlösung mit folgenden 4 Faktoren: phonematische Verarbeitung, verbal-auditives Kurzzeitgedächtnis, basaler Hörverarbeitungsfaktor, Hörverarbeitungsfaktor von redundanzreduzierter Sprache. Fazit Mit diesen Ergebnissen liegt ein vorläufiges Modell zentral-auditiver Prozesse unserer AVWS-Testbatterie sowie ein erster Beitrag zur Konstruktvalidität vor.

The factor structure of Form Y of the State-Trait Anxiety Inventory (STAI-Y) was examined with 1,862 Japanese adult workers (1,509 men, 353 women). The initial principal component analysis extracted three factors based on the scree test. All 20 state (S-Anxiety) and 20 trait (T-Anxiety) items had dominant salient loadings on the first factor, which reflected “over-all anxiety.” The three factors identified by an oblique (promax) rotation were labeled “anxiety-absent,” “state anxiety-present,” and “trait anxiety-present.” All 20 items with dominant salient loadings on the first oblique factor were clearly grouped on the basis of their content, indicating the absence of anxiety. The second and third oblique factors, defined almost entirely by the STAI-Y anxiety-present items, clearly reflected the state-trait distinction in this sample of Japanese workers.

Patient advocacy is an important aspect of nursing care, yet there are few instruments to measure this essential function. This study was conducted to develop, determine the psychometric properties, and support validity of the Protective Nursing Advocacy Scale (PNAS), which measures nursing advocacy beliefs and actions from a protective perspective. The study used a descriptive correlational design with a systematically selected sample of 419 medical-surgical registered nurses. Analysis of the 43-item instrument was conducted using principal components analysis with promax rotation, which resulted in the items loading onto four components. The four subscales have sufficient internal consistency, as did the overall PNAS. Satisfactory evidence of construct, content, and convergent validity were determined. Implications for nursing practice include using the PNAS in conjunction with an educational program to enhance advocacy skills, which may help to improve patient outcomes.

- The tradition of the social representations is the framework of research that is part of a wider project focused on the role of mass media, as part of cultural system, and on processes of anchorage and labelling involved to define the events under observation. We studied the social representations of French riots of November 2005 on headlines of 21 Italian daily newspapers with different cultural and ideological orientation. The aims of research, of comparative character, were the exploration: of consistence of results emerged in previous investigations, and of role played from newspapers and from temporal distance by the events 1) on structural organization of representational field, related to lexicon of headlines, and 2) on differential characterization of the lexicon of headlines 2a) of 21 newspapers and 2b) of two periods, more or less near to the beginning of events. The population, composed by 468 headlines, was collected by October 30 to November 18, 2005. The textual data, related to words of headlines, and the extra-textual data, related to newspapers, to period of publication (I and II week), to signature and sex of journalists, have been processed by different steps of statistical package SPAD-T. According to the scree-test were extracted two factors able to explain 20.40% of total variance. Through the intersection between the two factors we analyzed the factorial plan that, by providing the information more synthetic and exhaustive as possible, highlighted the existence of four areas otherwise characterized by the newspapers, by the two weeks and by the signature and gender of journalists. The differential analysis of lexicographical characterization of each of the 21 newspapers and of two periods, allowed the confirmation and deepening of what emerged in the structural analysis. Overall results showed the non-neutrality of language used by the headlines. It was functional to ideological and cultural profile of source, to its geographical area of reference and to temporal distance from origin of events. Furthermore results showed processes of anchorage and la- beling referable to need to preserve and strengthen specific groupal identity of the source.

This study was designed to reassess and reconceptualize the multidimensional nature of organizational commitment. The Organizational Commitment Questionnaire of Porter, Steers, Mowday, and Boulian was administered to 259 employees representing five retail banks. Factor analysis (principal factor, promax rotation) yielded the three dimensions proposed by Porter, et al. in 1974. This conceptualization was inadequate because one dimension, i.e., desire to maintain organizational membership, overlaps the withdrawal construct. A similar criticism has been levelled against Meyer and Allen's 1991 model. Consistent with the three-dimensional attitude theory, organizational commitment was reconceptualized in terms of cognitive, emotive, and conative meanings. The proposed dimensions include normative commitment (amount of cognitive consonance with organizational norms), affective commitment (intensity of emotional attachment to the organization), and volitive commitment (extent of conative orientation towards organizational goals).

Resumo Este estudo objetivou elaborar a Escala de Comportamentos de Bullying (ECB), checando evidências de validade e precisão. Participaram 455 estudantes do ensino fundamental de escolas públicas e particulares de Parnaíba (PI), com idade média de 11,3 anos, em maioria do sexo feminino (53,5%). Todos responderam à versão preliminar da medida, de 30 itens, e perguntas demográficas. Realizou-se a análise dos eixos principais (AEP) (rotação Varimax), o Scree Test, e a análise paralela indicou a existência de uma estrutura tetrafatorial. Logo, realizou-se uma nova AEP, fixando a extração de quatro fatores, estes explicaram conjuntamente 47,7% da variância total, cujos alfas de Cronbach variaram de 0,60 a 0,79. Esses achados revelam que a ECB reúne evidências favoráveis de validade e consistência interna, podendo ser adequadamente utilizada em estudos futuros para conhecer os antecedentes e consequências do bullying.

AbstractExploratory Factor Analysis and Principal Component Analysis are two data analysis methods that are commonly used in psychological research. When applying these techniques, it is important to determine how many factors to retain. This decision is sometimes based on a visual inspection of the Scree plot. However, the Scree plot may at times be ambiguous and open to interpretation. This paper aims to explore a number of graphical and computational improvements to the Scree plot in order to make it more valid and informative. These enhancements are based on dynamic and interactive data visualization tools, and range from adding Parallel Analysis results to "linking" the Scree plot with other graphics, such as factor-loadings plots. To illustrate our proposed improvements, we introduce and describe an example based on real data on which a principal component analysis is appropriate. We hope to provide better graphical tools to help researchers determine the number of factors to retain.

Instruments assessing geriatric case managers’ perceptions of prescription abuse are limited. Based on a review of current literature and pilot testing feedback, 22 items were initially assembled to form an older adult Prescription Drug Assessment Questionnaire (PDAQ). Case managers ( N = 161) at an older adult agency located in a Midwestern state were surveyed using the instrument. Data were subjected to exploratory factor analysis using principal axis factoring (PAF) and Promax rotation, and Horn’s parallel analysis determined the number of extracted factors. PAF generated a final 11-item three-factor model accounting for 51% of total variance explained: Standard Assessment (Factor 1; four items; ∞ = .83), Assessment Belief (Factor 2; three items; ∞ = .74), and Problem Scope (Factor 3; four items; ∞ = .62). The older adult PDAQ is a brief, data-driven instrument with acceptable psychometric properties for assessing perceptions of prescription drug abuse and misuse assessment and counseling.
