Embodied Self

The purpose of present study is to develop and verify the questionnaire aimed at assessing the degree of unembodiment in the Internet as a consequence of using modern information technologies. The use of modern information technologies is associated with disembodiment, liberation of the Self from the body and related experiences. Immersion in virtual reality and “disembodiment” can cause the existential position of “unembodiement”, the features of which, according to the concept of the English psychologist R. Lang, are most clearly manifested in the clinic of schizoids. The study was conducted in the form of a psychodiagnostic survey, during which the reliability and validity of the developed method for assessing unembodiement on the Internet was tested. The main sample of the study was 809 people (31% of males), mostly university students, aged 17 to 25 years (M=18.73; SD=0.98). Smaller samples were used to study convergent and discriminant validity: 423, 324, 148 and 128 people. Correlations with measures of psychological consequences of Internet use, self-efficacy and life-meaning orientations reported convergent validity, and correlations with measures of intelligence and creativity reported discriminant validity. The results of principal component analysis and confirmatory factor analysis (CFI=0.936, TLI=0.925, RMSEA=0.055, SRMR=0.059) confirm the construct validity of the method, which includes three subscales (Unembodiment as Virtualization, The Preference of the Internet, and Vitality of the Embodied Self) and a general scale (Unembodiment in the Internet). The one-step reliability of the scales varied from 0.7 to 0.9. The scales Vitality of the Embodied Self and The Preference of the Internet had a high level of discrimination, the scale Unembodiment as virtualization ― moderate. The developed questionnaire meets the requirements of validity and reliability and can be used to study the phenomenon of unembodiment on the Internet.

Abstract. Varimax rotated principal component scores (VRPCS) have previously been offered as a possible solution to the non-orthogonality of scores for the Big Five factors. However, few researchers have examined the reliability and validity of VRPCS. To address this gap, we use a lab study and a field study to investigate whether using VRPCS increase orthogonality, reliability, and criterion-related validity. Compared to the traditional unit-weighting scoring method, the use of VRPCS enhanced the reliability and discriminant validity of the Big Five factors, although there was little improvement in criterion-related validity. Results are discussed in terms of the benefit of using VRPCS instead of traditional unit-weighted sum scores.

Introduction: Tobacco is the only legal product that kills a large proportion of its consumers when used as intended by its manufacturer. The effect of nicotine as a driving substance on smoking has been established for decades. Still, very little is known on how the biopsychosocial determinants relationship affects levels of nicotine addiction in smokers, especially in the urban low-income population. The study aimed to validate measurement scales related to biopsychosocial factors that will be used in the future study to evaluate biopsychosocial components that influence nicotine addiction among urban poor smokers. Methods: Exploratory factor analysis (EFA) using the principal component analysis with varimax rotation and Kaiser normalization was used to assess the factor structure. Then, the confirmatory factor analysis (CFA) was conducted to assess the unidimensionality, validity, and reliability of the latent construct. Results: EFA showed extraction of factors according to their original scales with all factor loading and communality's values were above 0.5. During CFA, factor loading less than 0.6 was deleted. Convergent validity verified by computing the Average Variance Extracted (AVE) for every construct range between 0.528 – 0.801. The Fitness Indexes achieved the required level (RMSEA=0.05, CFI=0.937, Chisq/df=1.7). Meanwhile, the Discriminant Validity Index range between 0.75-0.89, which is higher than the correlation coefficient value. Internal consistency assessed from Composite Reliability range between 0.714-0.965. Conclusion: The measurement scales are valid and reliable to assess the intended constructs among low-income male smokers in the urban area.

The leadership of teacher remains as an essentially topic of educational leadership currently and it becomes teacher’s main role in implementing the school development process. However, there are less studies done in Malaysian schools; even hardly see Malaysian teachers are prepared to be teacher leaders  due to also lack of reliable and valid instrument that measure teacher leadership within Malaysian context. Therefore, this paper aims to examine the readiness of Malaysian teachers to be selected as teacher leaders among other teachers. Secondly, it also aims to measure the reliability and validity of instrument on teacher leadership in the context of Malaysian teachers. A total of 189 secondary school teachers who have more than five years’ experience were selected to be the respondents to answer the 12 items on teachers’ readiness as teacher leaders based on two main constructs such as personal and professional readiness. Finding from the factor analyses (exploratory and confirmatory) indicated that items from the professional and personal readiness constructs have high convergent validity in measuring the relevant teacher leadership. In addition, values from the correlational matrix also indicated high values of discriminant validity. Hence, it was proved that the teacher leadership readiness instrument has high validity and reliability in examining teachers’ readiness as a teacher leader.

Although many body attitudes scales have been developed, none have been translated into Portuguese. This study aimed to translate the Ben-Tovim and Walker Body Attitudes Questionnaire and assess validity and reliability for a Brazilian sample. Women with ( n = 39) and without ( n = 57) eating disorders completed the scale, to assess discriminant validity. Convergent validity was assessed by the correlations between the scores and a measure of body dissatisfaction. The questionnaire was applied twice to controls after 1 mo. to evaluate reliability. Eating-disordered women had significantly higher mean scores on Feeling Fat, Disparagement, Salience and Lower Body Fatness, and lower scores on Attractiveness. No mean difference on Strength and Fitness was found. Most subscales were significantly correlated with the body-dissatisfaction measure. Test-retest coefficients ranged from .57 to .85. The translated version of the Body Attitudes Questionnaire seems to be a valid and reliable measure of body attitudes.

This research explores the mechanism by which the buyers and suppliers adopt different information technologies (IT) as they enter into buyer-supplier relationships. It further studies how buyers' technology choices influence suppliers' technology adaptation in an Influential Adaptation model. Using empirical data collected from the Society of Manufacturing Engineer's executives, a confirmatory factor analysis was used to improve measurement rigors including convergent validity, discriminant validity, and reliability. The Planning IT use sub-construct is developed for this study. The structural model results show that suppliers' adoption of IT use is largely influenced by buyers' level of IT use; however, there is no clear relationship pattern relating to suppliers' IT use.

Domestic cats are popular pets, and they have personalities, with stable behavior differences between individuals. Lately, feline behavior and personality have been studied with different approaches, for example, with owner-completed questionnaires. The majority of these studies, however, lack a sufficient validation and reliability assessment of the questionnaires used. We designed an online feline behavior and personality questionnaire to collect cat behavior data from their owners. Then, we ran a factor analysis to study the structure of personality and behavior in a dataset of over 4300 cats. For validation, we studied the internal consistency, test–retest reliability, inter-rater reliability, convergent validity and discriminant validity of this questionnaire and extracted factors. In addition, we briefly examined breed differences in the seven discovered factors: fearfulness, activity/playfulness, aggression toward humans, sociability toward humans, sociability toward cats, excessive grooming and litterbox issues. Most of the rank ordering of breeds within each trait paralleled what has been found in previous studies. The validity and reliability of the questionnaire and factors were good, strengthening owner-completed questionnaires as a method to collect behavioral data from pet animals. Breed differences suggest a genetic background for personality. However, these differences should be studied further with multidimensional models, including environmental and biological variables.

Risk Scale

The COVID-19 pandemic scenario has a psychological impact on individuals and society. A higher level of perceived risk concerning COVID-19 has been found when compared to other potential health threats. A misperception of risk in contrast with the real risk may lead people to develop disruptive cognitive, affective, or behavioral responses to the COVID-19 pandemic, namely, coronaphobia. Validated instruments are needed to evaluate such responses. This work aims to validate the COVID-19 Perceived Risk Scale (C19PRS) and the COVID-19 Phobia Scale (C19PS) in the Portuguese population. The two scales were translated from English to Portuguese using the back-translation technique. The cultural adaptation was framed in the context of establishing the validity and reliability of the instruments. In two studies, C19PRS and C19PS were validated for the adult Portuguese population (N = 1122; women = 725 (64.6%); mean age of 31.91 years old) through exploratory factorial analysis, followed by a confirmatory factorial analysis. Convergent validity was calculated by composite reliability (CR) and average variance extracted (AVE) values. Discriminant validity was assessed by square roots of the AVE values and their comparison with the C19PRS and C19PS dimensions’ cross-correlations. Both C19PRS and C19PS present a good adjustment model and solid reliability and validity and have significant correlations with fear of COVID-19 and COVID-19 anxiety scales.

This article aims to develop a short form of the locus of control scale. The study was conducted in two stages: a study of 66 respondents as pilot testing which aims to test content validity, structure validity, and internal consistency. Study 2 was conducted on 328 respondents used to test the validity and reliability of the scale evaluated by the PLS-SEM method (such as internal consistency, convergent validity, and discriminant validity). The analysis concludes that the 8-item locus of control scales tested have adequate validity and reliability. A short form locus of control scale was developed and validated in this study, so it can be used in future research and evaluation for HR management practitioners in employee selection Keywords: locus of control, EFA, CFA, scale construction
