OBJECTIVE: to present the result of the validity and reliability studies concerning the Scale for the Predisposition to the Occurrence of Adverse Events (EPEA). METHOD: construct validity was based on Principal Components Analysis. RESULTS: reliability verified through Cronbach's alpha indicated good reliability (structure α=0.80; process α=0.92). CONCLUSION: based on its psychometric indicators, the EPEA can be considered a valid measure to assess the attitudes of nurses in relation to factors that potentially lead to the occurrence of adverse events in ICUs.

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.

- Abstract The paper consists of two parts. The first is more general: it introduces to university ranking, shows the leading international ranking, discusses the uses people make of rankings. The second focuses on Italian ranking Censis-la Repubblica developing two different kinds of analyses: after considering indicators validity and reliability, principal components analysis and cluster analysis are applied to a partial replication of Censis-la Repubblica data. A list of points to pay attention comes out of these analyses: it can be useful when defining rankings of complex institutions such as universities.Key words: ranking, university ranking, Censis-la Repubblica, validity and reliability, normalisation and combination of indicators.

Tool Position

Eighteen subjects practiced a video game of bombing and air combat maneuvering, Phantoms Five®, on an APPLE® microcomputer for 10 minutes a day for 15 days. The dependent variable was the combined score for number of hits and number of targets. Performance stabilized from Days 8–15 with a pooled reliability of .904. Eight reference tests which theoretically measure cognitive, perceptual, quantitative, and motor skills were selected and used as independent variables. Stabilized performance on these tests was observed after a period of practice which was predetermined from previous experimentation. Attributes of the Phantoms Five® were isolated using a structured job analytic tool (Position Analysis Questionnaire, PAQ). A principal components analysis of the measures that correlated with the dependent variable resulted in a one factor solution explaining 66 percent of the variance. It was concluded that construct validity was established since there was a strong similarity between the attribute requirements attained by correlating the stabilized scores of independent and dependent variables and by the PAQ analysis of task functions.

The purpose of this study was to test the reliability, validity, and effectiveness of a health-related quality of life (HRQOL) instrument—the MiniAQLQ—among persons with asthma who were using a web-based intervention for guided self-management (www.MyAsthma.com). The MiniAQLQ was completed online in 1999 by 307 participants referred to www.MyAsthma.com by their primary care physicians. Construct validity of the MiniAQLQ was assessed by principal components analysis; reliability was estimated using Cronbach’s alpha coefficient; and differences in means between pretest and posttest were analyzed using paired t test. The analysis produced four empirically meaningful factors with reliability of scores ranging from 0.65 to 0.94. Participants reported significant improvement in HRQOL after participating in this intervention. The four factors (activities, symptoms, emotions, and environment) generated by the principal components analysis empirically supported the four domains used in the development of the MiniAQLQ. Scores for the four factors were internally consistent and assessed the distinct domains. The MiniAQLQ appears to be a psychometrically sound instrument for measuring HRQOL online among asthma patients who are participating in online interventions.

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.

The aim of the present study was to investigate the construct validity of the Piers-Harris Children's Self-concept Scale with a group of 511 (264 girls, 247 boys aged 9 to 12 years) Greek children. Principal Components Analysis was performed. Six factors emerged, i.e., Behavior, Anxiety, Intellectual and School Status, Popularity, Physical Appearance and Attributes, and Self-contentment.

Item Scale

In order to test the validity of a Five Factor Model of personality on horses, a questionnaire was replicated from a previous study, with an added option of don’t know to the traditional 5-point Likert scale. Raters responded to seventeen items of the 60-item scale with don’t know responses greater than 10% of the time and these seventeen items were subsequently removed from the study. A Principal Components Analysis was used with the remaining items, resulting in eight factors: Neuroticism, Active, Conscientiousness, Agreeableness, Openness, Social Extraversion, Temperamental, and Disciplined. These components correspond well to the five components extracted in the original study, indicating good reliability of the scale. However, 17 items from the original questionnaire were deemed irrelevant by raters, indicating a threat to validity. Though the remaining items were able to be used in analyses, further studies should examine if these are in fact the most effective items to use in the investigation of equine personality.//
