The objective of this paper is to obtain indicators to allow to measure the happiness degree for a sample of workers, through the Alarcon Happiness Scale and the Subjective Happiness Scale. It was applied on service companies295 employees working in Barquisimeto, Venezuela. The scale consists of 27 Likert-type items with five response alternatives. Construct reliability and validity was set through the Cronbach alpha statistic and exploratory factor analysis with the principal component method, and Varimax-type orthogonal rotation prior result of the Kaiser-Meyer-Olkin test. The results obtained through various statistical tests pointed to the adequacy of the happiness scale, its validity and reliability, since the four factors (positive life meaning, satisfaction with life, personal fulfillment and joy for life) explain 90.1% of a worker’s happiness. In conclusion, it can be considered that workers expresses full happiness instead of temporary states thereof.

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.

There is much literature on visual literacy across different fields of knowledge. Even so, generally there is a gap of literature that deals with measuring mathematical visual literacy skills. The objective of this paper is to produce empirical data on reliability and validity of mathematical visual literacy skills instrument. The development of items was based on the skills outlined Avgerinou’s VL Index (2007. The early stage in validating the instrument required researchers to seek face validity and content validity from panels of experts. Face validity was based on subjective judgements of the items. Meanwhile, content validity was determined by Content Validity Index (CVI) which is computed using Item-CVI (I-CVI) and Scale-CVI (S-CVI). Each mathematical visual literacy skills had accepted S-CVI values ranging from 0.86 to 1.00 but items with low I-CVI values were deleted. Next, construct validity and reliability was determined by using Exploratory Factor Analysis (EFA) and Cronbach’s alpha respectively. The instrument, consisting of 43 items was assessed on 428 pre-university students. Students’ responses were scored using analytical rubric developed by researchers. Using Principal Component Axis (PCA) and varimax rotation, EFA was carried out where 40 retaining items were extracted to 7 factors, representing each visual literacy skills. Kaiser-Meyer-Olkin (KMO) of 0.721, significant Bartlett’s Test of Sphericity (BTS), communalities anti images ranging between 0.308-0.721 and 0.503-0.835 respectively, 7 extracted factors explaining 53.685% of the total variance, factor loadings of ±0.520 and more, and overall Cronbach’s alphas of instrument recorded at 0.82, explained the complete validity and reliability of the instrument.

AbstractPurpose:The PAtient SAtisfaction with Psychotropic (PASAP) scale is a self-completed questionnaire measuring satisfaction with psychotropic medication. The aim of the study was to describe its development in French and its psychometric properties.Materials and methods:Scale construction was based on an extensive search of the literature. The item reduction process required semi-structured interviews of psychiatric outpatients (n = 30). The final version of the PASAP is a 9-item, 5-point Likert-type scale, covering the scope of effectiveness and adherence. To assess the psychometric properties of the scale, French patients with an acute manic episode (n = 314) from a large European observational cohort completed the PASAP scale 3 months after psychotropic treatment initiation/change. Internal validity and reliability were assessed using principal component analysis (PCA). Concurrent validity was assessed using comparisons to physician-rated satisfaction with life, illness severity, mood relapse, compliance and side effects.Results:Participation rate was 68.4%. PCA was in favour of uni-dimensionality. Cronbach's α coefficient was 0.85 (95%CI 0.83–0.88). All five concurrent measures were significantly associated with the PASAP score.Conclusion:The PASAP scale showed good psychometric properties in a large bipolar population and thus seems adequate for evaluating treatment satisfaction. Its short length and good acceptability makes it suitable for clinical research.

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.

Background: Hope is essential for patients with acute myocardial infarction, which is often regarded as an active coping for those with life-threatening diseases. Higher hope consistently is related to better health outcomes. However, the instrument for assessing hope has not been previously tested among Thai patients. Objective: This study aimed to assess the validity and reliability of the Hope Scale among Thai patients with acute myocardial infarction patients. Methods: This was an instrument validation study conducted from March to December 2020. A total of 213 patients with acute myocardial infarction were included and selected using a simple random sampling. The back-translation method was used to translate an English version to a Thai version of the scale. Principal Component Analysis (PCA) and Cronbach’s alpha were used for construct validity and reliability. Results: The findings showed that the Cronbach’s alpha of the Thai version of the Hope Scale was acceptable (.75), and the scale consists of four factors, which explained 63.36 % of the total variance. Communalities in each factor ranged from .45 to .84. Overall, the appearance of the factor structures was reasonable and understandable. Conclusion: The reliability and validity of the Thai version of the Hope Scale were suitable for the measurement of hope in Thai patients. This scale can be used by nurses and others to assess hope in Thai patients with acute myocardial infarction. Funding: This study received funding from the 90th anniversary of Chulalongkorn University Fund (Ratchadaphiseksomphot Endowment Fund), Chulalongkorn University, Bangkok, Thailand (GCUGR1125633058M).

Supply chain management (SCM) has become an effective tool now a day to survive in this competitive world. Organizations do their best to improve performance by adopting better supply chain (SC) performance indicators. In this paper 19 key performance indicators (KPI) were identified based on strong literature support in consultation of practitioners and consultants in the field of non-livestock retailing (NLR). NLR is the retailing of agriculture and horticulture products. The technique of factor analysis using principal component analysis with Varimax rotation has classified KPI into four factors as; inventory metrics, customer metrics, flexibility metrics and growth and learning metrics. Structural Equation Modelling (SEM) approach was used to develop and validate a model for measuring SC performance of organized NLR industry based on KPI. The data for analysis was collected from top 10 organized NLR players operating in Punjab, Chandigarh, New Delhi and Gurgaon in India. The results were subjected to rigorous statistical tests for reliability and validity. Finally, these classified KPI were presented in the form of a model to measure SC performance of organized NLR industry using SEM.

Background/objective The ADL-focused Occupation-based Neurobehavioral Evaluation (A-ONE) can be used to evaluate both performances of activities of daily living (ADL) tasks and neurobehavioural problems that interfere with ADL task performance among clients with neurological disorders. Research studies have demonstrated acceptable psychometric properties of the original version of the A-ONE as well as the Rasch analysed version. The aim of this study was to examine the reliability and validity of the Japanese version of the A-ONE (A-ONE J). Methods Rasch analysis was performed on data obtained from eight different hospitals in Japan on performances of 150 individuals diagnosed with a stroke based on the functional independence (FI) scale items. The rating scale structure was investigated and internal validity and reliability were examined. Unidimensionality of the items was examined by mean square infit values and principal component analysis of residuals. The targeting between person ability and item difficulty was explored, as well as the separation reliability. Finally, psychometric values and item difficulty hierarchies obtained in this study were compared to the original Rasch analysis of the A-ONE. Results The rating scale structure might be improved by collapsing two categories twice (from five categories to three categories). Unidimensionality of the items was obtained for 20 items. Targeting was acceptable, and separation reliability for item calibrations was high and acceptable for people. Conclusion/limitations: This study provides important information regarding the possibilities for revising the ordinal A-ONE J FI Scale, converting it into a unidimensional scale. Further study with increased and more diverse sample is needed.
