The aim of this study was to investigate the dimensions of Interpersonal Trust Scale using Exploratory Factor Analysis and Confirmatory Factor Analysis in emerging adulthood sample. Convenience sampling used as sampling technique for EFA (N=320) and CFA (N=485). Four dimensions identified by EFA were Exploitation Institutional Factor reflecting one’s trust to an institution and also caution to exploitative condition; Role Trust reflects one’s trust to certain figure in performing their social role; Sincerity measures one’s trust that others are sincere and honest; and Trust of the Future reflects one’s trust about something that has not happened. This factor solution was cross-validated using CFA and obtain two remaining, namely Caution dan Sincerity. Reliability of this scale is inadequate for practical purpose and might be useful to use other technique for reliability testing instead of internal consistency.

PurposeIn the age of Industry 4.0 (I4.0), digital technologies (DTs) and the technologies' application in supply chain activities have become more important. On the other hand, global pressures for corporate social responsibility in the sustainable production of products are increasing. Accordingly, the purpose of this research is to develop and validate an instrument to measure the impact of digital supply chain (DSC) activities on the sustainable performance of manufacturing companies.Design/methodology/approachIn the first step, through an in-depth study of the relevant literature, a conceptual model was developed and a questionnaire containing 51 indicators was designed. The questionnaire was distributed among 356 top managers and experts of the Iranian manufacturing companies, whereby finally 233 sound questionnaires were returned, yielding a response rate of about 64%. Exploratory factor analysis (EFA) was used to identify constructs and sub-constructs and the relationship between them was investigated using the partial least squares structural equation model (PLS-SEM) method.FindingsBased on the obtained results, three constructs were identified, namely main activities (including sub-constructs: digital supplier, digital manufacturing, digital logistics and innovation and digital customer), support activities (with sub-constructs digital performance, DT and digital human resources) and sustainable performance (with sub-constructs of economic sustainability, environmental sustainability and social sustainability). The designed tool has excellent psychometric properties. The values of t-statistic = 11.07 and β = 0.602 indicate the positive impact of the DSC main activities on sustainable performance. Similarly, t = 2.42 and β = 0.149 prove that DSC support activities have a positive impact on sustainable performance. Also, based on the obtained values (t = 13.16 and β = 0.629), support activities have a significant impact on the main activities of the DSC. Finally, based on the calculated goodness-of-fit (GoF) index value (0.522), this paper concluded that the proposed model has high credibility.Research limitations/implicationsValidation of the model is based on the answers received from the Iranian manufacturing companies. Therefore, caution should be taken regarding the generalizability of the results.Practical implicationsThe proposed model presents a holistic view of the application of DTs in the supply chain and the DTs' impact on sustainable performance which might help manufacturing companies, particularly the Iranian companies to obtain a broader knowledge of the importance of DTs and DTs' usage toward responding to the challenges of today's complex business environment.Originality/valueThis study is among the first of the study's kind that attempts to develop and validate an instrument to measure the impact of DSC activities on the sustainable performance of manufacturing companies.

Confined space workers do a wide range of tasks, many of which have a significant risk of hazardous exposure. Hence, a reliable and valid questionnaire is important in assessing the knowledge, attitude, and practice (KAP) of workers in this field. The present study was conducted to develop and validate a questionnaire that could assess the KAP for safe working in a confined space. The questionnaire went through a development and validation process. The development stage consisted of a literature review, expert’s opinion, and evaluation by experts in the field via cognitive debriefing. The validation stage encompassed exploratory and confirmatory parts to investigate the psychometric properties of the questionnaire. A total of 350 participants were recruited among confined space workers from two oil and gas companies in Malaysia. The two-parameter logistic item response theory (2-PL IRT) analysis was used for the knowledge section. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used in the attitude and practice sections of the validation stage. The development stage resulted in 30 items for knowledge, attitude, and practice sections. Items in the knowledge section showed an acceptable difficulty and discrimination, as noted during the 2-PL IRT analysis. The EFA resulted in a one-factor model for attitude and practice sections, and contained 18 items, with factor loading > 0.4. The Cronbach’s alpha was 0.804 and 0.917 for attitude and practice sections, respectively. The CFA for attitude and practice sections indicated a good model fitness (Raykov’s rho = 0.814 and 0.912, respectively). All items indicated good reliability and valid psychometrics for determining KAP on safe working in a confined space.

Homonegativity refers to prejudice towards same sex relationships. We examined the psychometric properties of the 12-item Modern Homonegativity scale (internal consistency reliability, construct validity), exploratory factor analysis, and factors associated with homonegativity. The study used survey data from 198 Asian Americans in 2019 (mean age = 34, SD = 14). The scale demonstrated good reliability (ordinal alpha = 0.93) and satisfactory model fits for a 4-factor construct (RMSEA = 0.19, CFI = 0.97, TLI = 0.9, SRMR = 0.07). The construct validity showed that greater homonegativity associates with lower levels of acculturation, social norms about HIV testing, and fewer years in immigration. Overall, the Modern Homonegativity scale was found to be a reliable and valid measure to assess prejudice towards Asian American gay men. Future efforts to validate the scale among Asian Americans should consider investigating these properties among a more diverse sample with regards to geographies and sub-cultures.

In the past decades, thanks to the widespread use of the new information and communication technologies, nomophobia has emerged as a contemporary psychological disorder. More in detail, it has been defined as the modern fear of feeling disconnected, being out of mobile phone contact, and being unable to access information and/or communicate with others. Few authors have used an Arabic version of the Nomophobia Questionnaire, even though its psychometric properties are not well known and have been poorly investigated from a formal rigorous standpoint. Our research objective was to develop and validate the Arabic version, administering it to a sample of adolescents and young adults in a country characterized by a high mobile network coverage. A total of 512 subjects (aged 21.62±4.33 years, median 20 years), equally distributed between males and females, and based in Kuwait, volunteered to take part in the study. The confirmatory factor analysis did not show a completely satisfactory fitting with the original factor structure. The exploratory factor analysis showed that four factors had 57.24% variance. Overall Cronbach's alpha coefficient was 0.879. However, the coefficient increased from 0.645 to 0.849 with respect to the original factor structure. Scores (and mean scores) were 4.25±1.59 (21.23±7.95), 2.95±1.33 (17.68±7.97), 4.48±1.78 (8.96±3.56), and 4.98±1.52 (34.84±10.67) for factors I, II, III, and IV, respectively, whereas the overall score (and mean overall score) was 4.14±1.13 (82.71±22.68). In our sample, no subject (0.0%) was without nomophobia, with 92 (18.0%) and 288 individuals (56.2%) reporting mild and moderate nomophobia levels, respectively. Approximately a quarter of the recruited sample (132 subjects, 25.8%) had severe nomophobia level.

Introduction: A family operates as a dynamic system comprising various subsystems and is continually interacting with its environment. Therefore, it is essential to comprehend the underlying principles of family functioning. One of the most commonly used models for describing family functioning is the Circumplex Model of Marital and Family Systems (Olson & Gorall, 2003). Aims: In this study, we aimed at examining the factor structure and internal consistency reliability in the Croatian version of the Family Adaptability and Cohesion Evaluation Scale IV Package, which measures family functioning through family cohesion and flexibility at the balanced and unbalanced levels, as well as family communication and family satisfaction. Methods: Confirmatory factor analysis (CFA) and exploratory factor analysis (EFA) were performed using a convenient sample of 528 participants. Results: CFA revealed that the Croatian version of the FACES IV Package does not fit the theoretical model of the original factor structure in this preliminary study. The exceptions were the Family Communication Scale and Family Satisfaction Scale, which showed satisfactory parameters. The results of the EFA of FACES IV showed a 5-factor model solution. Conclusions: The Croatian version of the FACES IV Package is not completely suitable for use in the national context. Thus, given these preliminary findings, further testing on a more representative or clinical sample is recommended. Keywords: confirmatory factor analysis (CFA), exploratory factor analysis (EFA), family functioning, FACES IV Package, family satisfaction

The study of participants’ motivations in sporting events is a recurring topic that provides valuable information for stakeholders interested in the event’s success. This motivation structure varies between geographies and evolves, so addressing new case studies from fresh perspectives updates and enriches the knowledge on the subject. Through a survey of 416 participants in the Córdoba Half-Marathon, Spain, we aim to explore the existence of new dimensions of motivation to participate in running events, as well as to analyse if there are statistically significant differences between men and women in their participation motivations and the magnitude of these differences. To this end, an Exploratory Factor Analysis (EFA) has been conducted, and the Mann–Whitney U and Hedges’ G statistics have been utilised. The results of this research complement previous studies with two new dimensions of motivation: inclusivity at various levels and the posting of images on social networks. Additionally, the leading role of female participants is evident, as they are more motivated than men to compete and surpass themselves.

Competing viewpoints on the independency or interdependency of Skinner’s verbal operants have been discussed in the literature and with empirical support for both positions generated using single-case research methods. Our study provides support for the interdependency of the verbal operants using items contained in the Verbal Behavior Milestones Assessment and Placement Program as a measure of broader skill acquisition in each verbal operant category and across skill complexity levels. The result of an exploratory factor analysis conducted across 85 participants with autism suggested that items did yield factors consistent with the verbal operants, rather items appeared to cluster in terms of skill complexity producing a best-fit 2 factor model. Together with prior research showing untrained cross-operant transfers, results fail to support Skinner’s verbal behavior taxonomy distinguishing between the verbal operant categories as independent constructs, with implications for how behavior scientists and analysts describe language development and assess and treat language deficits of individuals with autism.

The ability to achieve and maintain a competitive advantage in the long term is one of the most valuable abilities of a company in the modern economy. Companies strive to achieve a competitive advantage in order to be recognised by customers, which is expected to lead to increased revenues and profits. It is important to choose factors serving to achieve a competitive advantage. More desirable are factors that are difficult to copy by competitors and adapted to the opinions and needs of consumers. The aim of the article is to identify the sources of competitive advantage of enterprises in the opinion of consumers from Slovakia and Poland. The article analyses the literature on the subject and uses the methods of descriptive statistics and exploratory factor analysis (EFA). The analysis of the results is based on surveys conducted on a group of consumers from Slovakia and Poland using statistical software. A questionnaire assesses the importance of competitive factors utilised by companies. The obtained results confirm that quality is an important source of competitive advantage and country is a variable differentiating the selection of sources of competitive advantage. The research contributes to the ongoing scientific discussion, more specifically taking into account the consumer focus. To summarise, gaining a competitive advantage is a complex task influenced by a number of factors. To a large extent, they are related to the capacity for innovation, to the resources possessed, including human capital, and to the ability to respond to market needs and the use of marketing tools. The research contributes to the development of theories in the field of enterprise competitiveness, and its results can serve as recommendations for enterprise managers to identify the key sources of enterprises’ competitive advantage.

The objective of the paper is to develop a validated scale to measure the factors that cause delays in infrastructure projects. The study employed a standard three phase scale development procedure of Churchill (1979) which was augmented subsequently by Nunnally, Bernstein and Berge (1994) and Prakash and Phadtare (2018). In phase one, 73 factors that cause delays were identified, which were reduced to 45 based on literature review and expert opinions. These 45 factors were subjected to an exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) in phase two and three, respectively, to refine and establish convergent, discriminant and nomological validity of the scale. The study confirms that delays in infrastructure projects happen due to six factors, i.e., Contractor Related Factors (CON); Consultant Related Factors (CS); External Factors (EX); Labour Related Factors (LR); Material Related Factors (MT) and Design Related Factors (DJ). The study is particularly useful for the firms engaged in the development of infrastructure projects globally, as it identifies and ranks the factors that cause delays in a project. However, the study being confirmatory in nature only confirms the grouping of factors causing delays and is also limited by the possibility of sampling error.
