Components Analysis

A study was conducted to develop a scale for assessing computer anxiety. The scale was administered to 152 psychology students. The responses were then subjected to both item and principal components analysis. Computer anxiety was significantly and negatively correlated –.48 with the total amount of experience individuals had had with computers. Graduate and undergraduate students did not differ significantly in anxiety. When controlling for amount of experience with computers, clinical psychology students reported more anxiety than industrial-organizational psychology students, but men and women did not differ significantly in anxiety.

Research using Knoblauch and Falconer's Ego-Grasping Scale is reviewed. Using a sample of 695 undergraduate students, the scale had moderate reliability (Cronbach alpha, odd-even numbered items, and test-retest), but a principal-components analysis with a varimax rotation identified five components, indicating heterogeneity in the content of the items. Lower Ego-Grasping scores appear to be associated with better psychological health. The scale has been translated and used with Korean, Kuwaiti, and Turkish students, indicating that the scale can be useful in cross-cultural studies.

The purpose of this study was to assess validity and reliability of the Physical Educators’ Attitude Toward Teaching Individuals with Disabilities III (PEATID III; Rizzo, 1993) for future professionals. Participants (N = 3,464) were undergraduate students enrolled in the introductory adapted physical education course at 235 colleges and universities. Construct validity was obtained through principal components analysis with oblique rotation and supported by principal components analysis with varimax rotation. Results showed that PEATID III measures three factors: (a) outcomes of teaching students with disabilities in regular classes, (b) effects on student learning, and (c) need for more academic preparation to teach students with disabilities. Reliability, as estimated through coefficient alpha, was .88 for the total scale and .71 or greater for each of the disability subscales.

Components Analysis

The present study examined the underlying dimensions associated with perceived risk for consumer products. Eighty undergraduate students evaluated 40 products using seventeen rating questions. Principal components analysis was then performed on the ratings. Results indicated the presence of three underlying components or dimensions along which the products varied. The first component dealt with qualitative aspects of the risks associated with a product, such as the degree to which potential hazards were known (or knowable) and the immediacy of their onset. The second component concerned subjects' familiarity with the product. The third component was associated with quantitative aspects of the risks and reflected notions about the magnitude of the potential harm (in terms of the number of potential victims) that might be incurred as a result of using the product. Subsequent regression analyses revealed that each dimension was significantly related to subjects' rated intent to act cautiously with a product. Overall, these results suggest that people do not perceive consumer products unidimensionally. Rather, such perceptions are best conceptualized as reflecting multiple underlying facets.

Components Analysis

Sheehan's shortened form of Betts' Questionnaire Upon Mental Imagery is one of the most widely used inventories for measuring imaging. Participants were 562 undergraduate students (414 women and 148 men), with a mean age of 20.2 yr. In a principal components analysis followed by varimax orthogonal rotation for the Spanish version, eight factors were identified, six of which coincide with those of the original English version. Internal consistency was .92 (Cronbach alpha). Scores on the Betts Questionnaire Upon Mental Imagery correlated −.34 with those on the Gordon Test of Visual Imagery Control, .58 with those on the Vividness of Visual Imagery Questionnaire, and .02 with the Verbalizer-Visualizer Questionnaire.

Components Analysis

Data taken from the blood of 262 patients diagnosed for malabsorption, elective cholecystectomy, acute cholecystitis, infectious hepatitis, liver cirrhosis, or chronic renal disease were analyzed with three numerical taxonomy (NT) methods : cluster analysis, principal components analysis, and discriminant function analysis. Principal components analysis revealed discrete clusters of patients suffering from chronic renal disease, liver cirrhosis, and infectious hepatitis, which could be displayed by NT clustering as well as by plotting, but other disease groups were poorly defined. Sharper resolution of the same disease groups was attained by discriminant function analysis.
