Opis:: The paper presents arguments that advocate for application of the multi-group confirmatory factor analysis as a tool for constructing sentiment indicators in business surveys. Reliable measurement and comparisons of the sentiment mean between periods require measurement invariance on its three basic levels-configural, metric and scalar invariance. It is hypothesized that only sets of questions that are internally coherent can serve as a group of proxies for business sentiment indicator. An attempt to construct two different sentiment indicators for manufacturing industry is performed. The results show that only for the set of coherent proxies it is possible to estimate model with measurement invariance.

Opis:: Workplace innovation enables the development and improvement of products, processes and services leading simultaneously to improvement in organisational performance. This study has the purpose of examining the factor structure of workplace innovation. Survey data, extracted from the 2014 APS employee census, comprising 3,125 engineering professionals in the Commonwealth of Australia’s departments were analysed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). EFA returned a two-factor structure explaining 69.1% of the variance of the construct. CFA revealed that a two-factor structure was indicated as a validated model (GFI = 0.98, AGFI = 0.95, RMSEA = 0.08, RMR = 0.02, IFI = 0.98, NFI = 0.98, CFI = 0.98, and TLI = 0.96). Both factors showed good reliability of the scale (Individual creativity: α = 0.83, CR = 0.86, and AVE = 0.62; Team Innovation: α = 0.82, CR = 0.88, and AVE = 0.61). These results confirm that the two factors extracted for characterising workplace innovation included individual creativity and team innovation.

Tytuł:: The broad factor of working memory is virtually isomorphic to fluid intelligence tested under time pressure
Autorzy:: Chuderski, Adam
Opis:: How much overall variance in fluid intelligence (Gf) can be predicted by four working memory (WM) functions: storage capacity, attention control, relational integration, and updating was investigated under time pressured Gf testing. Confirmatory factor analysis indicated that the broad WM factor, which was subsumed by these four WM functions, shared 83.4% of variance with Gf tested under pressure, whereas a reanalysis of previous data with the same model showed that only 58.2% variance was shared with virtually untimed Gf tests. Moreover, in timed Gf tests, only the easiest, early items contributed to the WM-Gf correlation, whereas in untimed tests also the hardest, late items were linked with Gf. These results suggest that the measurement of “fast” intelligence primarily taps the functions of WM, whereas “slow(er)” intelligence depends also on some other cognitive processes beyond WM.

Tytuł:: High intelligence prevents the negative impact of anxiety on working memory
Autorzy:: Chuderski, Adam
Opis:: Using a large sample and the confirmatory factor analysis, the study investigated the relationships between anxiety, working memory (WM) and (fluid) intelligence. The study showed that the negative impact of anxiety on WM functioning diminishes with increasing intelligence, and that anxiety can significantly affect WM only in people below average intelligence. This effect could not be fully explained by the sheer differences in WM capacity (WMC), suggesting the importance of higher-level cognition in coping with anxiety. Although intelligence moderated the impact of anxiety on WM, it was only weakly related to anxiety. In contrast to previous studies, anxiety explained the substantial amount of WMC variance (17.8%) in less intelligent participants, but none of the variance in more intelligent ones. These results can be explained in terms of either increased motivation of intelligent but anxious people to cope with a WM task, or their ability to compensate decrements in WM.

Opis:: The aim of the study is to present a model of measuring the quality of market information as a second-order factor model. To receive this model the confirmatory factor analysis (CFA) was used. The rationale for creating the second-order model was high correlation of the four originally assumed factors in the first-order measuremment model as well as substantive reasons. The first-order factors under consideration were reliability, completeness, relevance, and timeliness of information. The study used orginal data of new product projects in which we measured reliability, completeness, usefulness and timeliness of the information available in the new product development. The sample was randomly selected from the national population of high and medium-high technology firms, employing more than 49 people. We received a second-order general factor – quality of the information – that explained the high correlation among the four first-order factors. The resulting model had an acceptable level of data fit and relevant and high factor loadings for both, first and second order models.

Opis:: The aim of this research is to adapt the Workplace Bullying Scale (Tınaz, Gök & Karatuna, 2013) to Albanian language and to examine its psychometric properties. The research was conducted on 386 person from different sectors of Albania. Results of exploratory and confirmatory factor analysis demonstrated that Albanian scale yielded 2 factors different from original form because of cultural differences. Internal consistency coefficients are,890 -,801 and split-half test reliability coefficients, 864 -,808. Comfirmatory Factor Analysis results change from,40 to,73. Corrected item-total correlations ranged,339 to,672 and according to t-test results differences between each item’s means of upper 27% and lower 27% points were significant. Thus Workplace Bullying Scale can be use as a valid and reliable instrument in social sciences in Albania.

Tytuł:: Factor structure of suggestibility revisited : new evidence for direct and indirect suggestibility
Autorzy:: Polczyk, Romuald
Opis:: Yielding to suggestions can be viewed as a relatively stable individual trait, called suggestibility. It has been long proposed that there are two kinds of suggestible influence, and two kinds of suggestibility corresponding to them: direct and indirect. Direct suggestion involves overt unhidden influence, while indirect suggestion concerns influence that is hidden, and the participant does not know that the suggestibility is being measured. So far however, empirical evidence for the existence of the two factors has been scarce. In the present study, more sophisticated and reliable tools for measuring suggestibility were applied than in the previous research, in the hope that better measurement would reveal the factor structure of suggestibility. Two tests of direct suggestibility were used: the Harvard Group Scale of Hypnotic Susceptibility, Form A, measuring hypnotic susceptibility, and the Barber Suggestibility Scale, measuring non-hypnotic direct imaginative suggestibility. Three tests served to measure indirect suggestibility: the Sensory Suggestibility Scale, measuring indirect suggestibility relating to perception; the Gudjonsson Suggestibility Scale, measuring the tendency to yield to suggestive questions and changing answers after negative feedback; and the Emotional Dialogs Tests, measuring the tendency to perceive nonexistent aggression. Participants and procedure In sum, 115 participants were tested, 69 women, 49 men, mean age 22.20 years, SD = 2.20. Participants were tested in two sessions, lasting for a total of four hours. Results Confirmatory factor analyses confirmed the existence of two uncorrelated factors of suggestibility: direct and indirect. Conclusions Suggestibility may indeed involve two factors, direct and indirect, and failure to discover them in previous research may be due to methodological problems.

Opis:: In this paper we conduct a three step analysis of business tendency survey data in order to establish (1) common factors driving responses to groups of questions in the business tendency survey conducted among firms in the manufacturing industry in Poland, (2) factors responsible for respondents’ answers regarding assessments (present) and expectations (future), and (3) interrelations between current assessments and expectations. We start by performing a check of the factor structure with multi-group confirmatory factor analysis (MGCFA) models in order to establish common factors responsible for sets of answers in the area of assessments and expectations, respectively. Then, we proceed with structural equation modeling (SEM) framework in order to define period specific relations between the factors. With the final structural model we show that most answers in the area of current assessments and expectations of companies are in line with the stylised facts. We also demonstrate that the companies’ response pattern did not change during the financial crisis.

Opis:: The area of human resources management is inseparably connected with the employee’s health protection, that is, according to the definition adopted by the WHO, ensuring the state of physical, mental and social well-being. The development of the Occupational Safety and Health management systems, especially the effectiveness of the action taken, building a safety culture, requires involvement of all of the organization members, which is backed by the law and safety standard requirements. Measurement of employee participation in the area of occupational health and safety is a component of the safety climate in a fairly limited scope, which is why the authors developed a model covering the legal and systemic aspects of employee involvement in health and safety at the workplace. The objective of the article is to identify factors which enable evaluation of the involvement level of all of the organization members in OSH with the use of confirmatory factor analysis. The study results, which were obtained using the PAPI method on a group of 195 organization representatives, allowed for the construction of a tool for the measurement of the employee involvement in OSH, characterized by proper and high accuracy and reliability levels. Using the developed tool, proven was the positive correlation between the size of the organization and the employee involvement level in OSH.
