This study proposed a model to explain the students' and teachers' intention to use (ITU) technology. A sample of 1,095 participants (503 students and 592 teachers) responded to a 15-item, 7-point scale designed to measure six variables: perceived usefulness (PU), perceived ease of use, attitude toward use (ATU), facilitating conditions, computer self-efficacy (CSE), and ITU technology. Results of this study showed that the six variables were valid in explaining the ITU technology for both student and teacher groups. Hypothesis tests revealed that eight of nine hypotheses were supported. Multigroup confirmatory factor analysis found support for full configural and metric invariance, and partial scalar invariance in the data. Finally, the results revealed that only two paths, PU → ATU and CSE → ATU were structurally invariant in the research model. Implications of this study are discussed and future research possibilities proposed. [ABSTRACT FROM AUTHOR]

We investigated the psychometric properties of the Italian version of the Dutch Work Addiction Scale (DUWAS) by using an Italian sample (N = 1,027) and a comparable Dutch sample (N = 7,523). We first conducted multigroup confirmatory factor analysis and reliability analysis. We then examined the correlations of the DUWAS with job demands, work-family conflict, job-related affective well-being, and psychological and physical strain. Results showed that a two-factor solution of the DUWAS was equivalent across the Italian and Dutch samples, with data supporting factor variance and covariance equivalence in addition to metric equivalence. Internal consistencies of the DUWAS and its subscales were adequate, and test-retest reliability showed a strong stability of the measure at one year. The DUWAS and its subscales showed a pattern of correlations in the expected direction with the adopted criterion measures. Overall, the Italian version of the DUWAS shows adequate validity and reliability. [ABSTRACT FROM AUTHOR]

Aim of the present study was to examine the construct validity of the trauma-related coping self-efficacy (CSE) scale. While assessing the psychometric properties of this 20-item scale among four different samples (514 victims of disaster, 1325 bereaved individuals, 512 victims of acute critical incidents, 169 severe bum victims), we found no measurement equivalence across groups. A shortened version was composed using only those items that were applicable to all types of potentially traumatic events (PTEs). In contrast to the CSE-20, the CSE-7 has a robust factor structure; factor structure and factor loadings were similar across study samples, indicating that it measured the same construct across different PTEs. These results offer strong support for cross-event construct validity of the CSE-7. Associations of the CSE-7 with posttraumatic stress symptoms showed the same pattern as with the CSE-20, indicating that the reduction in items did not diminish the scales' power to predict posttraumatic stress.

Various consumer values and perceived product attributes trigger consumptive behaviors of athletic team merchandise (Lee, Trail, Kwon, & Anderson, 2011). Likewise, using a principal component analysis technique on a student sample, a measurement scale was proposed that consisted of nine factors affecting the purchase of athletic team merchandise. Using confirmatory factor analysis and multi-group invariance technique, the factorial structure and measurement equivalence of the model (included a new factor) was validated on a more generalizable sample in the current study. The overall model fit the data well. The overall findings of the current study contribute to the literature by exploring and filling the gap between existing studies and more generalizable data found in the present study.

This article explores the cross-cultural equivalence of two composite measures of environmental concern derived from the International Social Survey Programme (ISSP): the pro-environmental views scale (PEVS) and the environmental awareness scale (EAS). Item response theory and multigroup confirmatory factor analysis were employed to evaluate comprehensively the target measures while focusing on a concrete cross-cultural comparison between Taiwan and the UK. The results indicated that both measures show nonequivalence to different extents. The PEVS presents substantial problems of validity in Taiwan, whereas in the UK it is a meaningful unidimensional measure if one item is excluded. Difficulties with construct equivalence, translation, and method bias were identified as potential causes of the scale's nonequivalence. The EAS is a suitable measure within both cultures, but it is affected by the cumulative effect of differential item functioning (DIF) that makes the comparison of group means imprecise. Taiwanese respondents' salient tendency to endorse higher response categories than expected for their latent levels of EA was determined as a potential cause of DIF, which may be related to bias induced by the response categories' labels. Above all, this study reminds the importance of examining carefully the measurements employed in cross-cultural research to avoid reporting findings that could be potentially misleading. • Two ISSP-based measures of environmental concern are nonequivalent across cultures. • The pro-environmental views scale is valid for the UK but not for Taiwan. • The environmental awareness scale (EAS) shows metric but not scalar equivalence. • DIF increases the group difference in scale scores on the EAS, favoring Taiwan. • Construct, method, and item biases were identified.
