Few tests have been designed to measure auditory imagery. This study assessed the factor structure and internal consistency of the Spanish version of the Clarity of Auditory Imagery Scale (CAIS). Participants were 234 undergraduate students ( M age = 19.6 yr.). Internal consistency reliability estimated by Cronbach's alpha was .82. In a principal components analysis followed by varimax orthogonal rotation, five factors were identified. Scores correlated moderately and positively with ratings on the Vividness of Visual Imagery Questionnaire–2 and negatively on the auditory scale of Betts' Questionnaire Upon Mental Imagery, but weakly and negatively with scores on the Measure of the Ability to Form Spatial Mental Imagery.

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.

We examined the factor structure and internal consistency of the Spanish version of the Gordon Test of Visual Imagery Control, as well as the correlations with scores on the Vividness of Visual Imagery Questionnaire and the Verbalizer-Visualizer Questionnaire, for a sample of 479 undergraduates. Principal components analysis, followed by varimax orthogonal rotation, identified the expected four factors (Movement, Misfortune, Colour, and Stationarity), which jointly explained 55% of the variance. The Gordon Test had a Cronbach α value of .69 and correlated significantly with scores on Marks' Vividness of Visual Imagery Questionnaire.

High Internal Consistency Reliability

We examined the factor structure and internal consistency reliability of the Spanish version of the Vividness of Visual Imagery Questionnaire which was applied to a sample of 850 secondary school students. Factor structure investigated by principal components analysis, followed by varimax orthogonal rotation, indicated that a single factor explained 37% of the variance. The internal consistency of the questionnaire was good (Cronbach α = 88) We conclude that the Spanish version of the questionnaire, like the English version, has a single factor and high internal consistency reliability.

Abstract Background Woman-centred care is recognised as a fundamental construct of midwifery practice yet to date, there has been no validated tool available to measure it. This study aims to develop and test a self-report tool to measure woman-centred care in midwives. Methods A staged approach was used for tool development including deductive methods to generate items, testing content validity with a group of experts, and psychometrically testing the instrument with a sample drawn from the target audience. The draft 58 item tool was distributed in an online survey using professional networks in Australia and New Zealand. Testing included item analysis, principal components analysis with direct oblimin rotation and subscale analysis, and internal consistency reliability. Results In total, 319 surveys were returned. Analysis revealed five factors explaining 47.6% of variance. Items were reduced to 40. Internal consistency (.92) was high but varied across factors. Factors reflected the extent to which a midwife meets the woman’s unique needs; balances the woman’s needs within the context of the maternity service; ensures midwifery philosophy underpins practice; uses evidence to inform collaborative practice; and works in partnership with the woman. Conclusion The Woman-Centred Care Scale-Midwife Self Report is the first step in developing a valid and reliable tool to enable midwives to self-assess their woman-centredness. Further research in alternate populations and refinement is warranted.

Fluency Task

The factor structure and internal consistency reliability of the Spanish version of the Verbalizer-Visualizer Questionnaire was analyzed. 969 male and female high school students completed the questionnaire and the Gordon Test of Visual Imagery Control. Factor analysis indicated that the questionnaire comprises five factors: “interest in words,” “dream vividness and frequency,” “verbal fluency,” “task performance difficulty,” and “ways of thinking and acting.” The internal consistency was very low (Cronbach α = .30). The correlation between scores and those on the Gordon test was statistically significant because N was large but very weak ( r = .08, p < .05). The questionnaire measured five distinct factors, and this should be taken into account when using the Spanish version rather than a coherent dimension.

Report Measure

The Avoidance of Environmental Tobacco Smoke (ETS) scale is a self-report measure of the avoidance of ETS by young adults. Initial use of the scale with 30 undergraduate students showed an internal consistency of .84 across 40 items and .90 in a refined 28-item instrument. In a sample of 241 students, a 20-item scale had an internal consistency reliability of .94 and a refined 10-item scale had an internal consistency of .86. In a sample of 95 mothers with a mean age of 36, the 10-item scale had an internal consistency of .81. In three distinct samples, significant known groups’ discrimination was found between smokers and nonsmokers. Psychometric analysis indicates that the scale merits further testing using a more heterogeneous sample from community and clinical populations to ensure its usefulness by clinicians and researchers interested in explaining, predicting, and preventing exposure to ETS.

Development And Validation

In the present studies, a scale was developed for measuring attitudes toward automation technology that reflect a potential for complacency. In the first, developmental study, a 20-item questionnaire consisting of statements concerning various aspects of automation was administered to 139 undergraduates at Catholic University. Factor analysis of the complacency potential rating scale (CPRS) revealed five independent factors, namely: general, confidence- reliance-, trust-, and safety-related complacency. The internal consistency reliability coefficients of the five factors and the scale as a whole were found to be high, and the scales revealed satisfactory test-retest reliabilities. The pattern of correlations among CPRS score, age, gender, computer use, and computer experience were consistent with previous studies examining attitudes toward microcomputer usage (Igbaria and Parasuraman, 1991). In the second, validation study, the 20-item CPRS was cross-validated on a sample of 175 undergraduate students at Drexel University. Factor analysis similarly revealed five factors with high alphas. The results indicate that the potential for complacency can be evaluated by assessing attitudes towards automation technology.
