In this research has been paid to the research and study of new concepts in management that is considered to the attention of many researchers in various fields including economics, social sciences, and political science and ... because of its strand nature. This study investigates the effect of social capital on job satisfaction of managers and employees in the State General Inspection Organization. The purpose of this study, the type of application and data collection methods, descriptive. This study is called correlation research because of the relationship between two or more variables. In this study has been investigated the model by using exploratory and confirmatory analysis statistics. The statistics society of this research is managers, experts and employees of the State General Inspection Organization. Confirmatory factor analysis of social capital in the first question of all questions except 58 and 61 t-value are acceptable to that question will be removed and the job satisfaction of first-order factor analysis of questions 2 and 31 are removed and values x 2 / df First-and second-order confirmatory factor analysis, and RMSEA of social capital and job satisfaction of first-and second-order model is indicative of the suitability and the value of x 2 / df and RMSEA T-value of the structural model and the necessary modifications are appropriate.

Aging involves changes in psychomotor performance. Few studies are focused on psychomotor skills among older people due, in part, to the inexistence of valid instruments in the field. The purpose of this article is to analyze the factor structure model of the Portuguese version of Exámen Géronto-Psychomoteur. The confirmatory factor analysis was completed in a sample of 497 older persons, aged between 60 and 99 years, with and without dementia (74.4% female; M = 78.0; standard deviation = 8.6). A baseline one-factor model was compared against 2 three-factor models (first and second order) that were developed based on the previous exploratory factor analysis. Fit indices for the one-factor model were slightly higher when compared with other models; however, the second-order model seems to be more representative of human behavior. The results of this study provide evidence to support a three-factor model: cognition, motor function, and physical aspects.

Background: Moral distress is a growing problem for healthcare professionals that may lead to dissatisfaction, resignation, or occupational burnout if left unattended, and nurses experience different levels of this phenomenon. Objectives: This study aims to investigate the factor structure of the Persian version of the Moral Distress Scale–Revised in intensive care and general nurses. Research design: This methodological research was conducted with 771 nurses from eight hospitals in the Mazandaran Province of Iran in 2017. Participants completed the Moral Distress Scale–Revised, data collected, and factor structure assessed using the construct, convergent, and divergent validity methods. The reliability of the scale was assessed using internal consistency (Cronbach’s alpha, Theta, and McDonald’s omega coefficients) and construct reliability. Ethical considerations: This study was approved by the Ethics Committee of Mazandaran University of Medical Sciences. Findings: The exploratory factor analysis ( N = 380) showed that the Moral Distress Scale–Revised has five factors: lack of professional competence at work, ignoring ethical issues and patient conditions, futile care, carrying out the physician’s orders without question and unsafe care, and providing care under personal and organizational pressures, which explained 56.62% of the overall variance. The confirmatory factor analysis ( N = 391) supported the five-factor solution and the second-order latent factor model. The first-order model did not show a favorable convergent and divergent validity. Ultimately, the Moral Distress Scale–Revised was found to have a favorable internal consistency and construct reliability. Discussion and conclusion: The Moral Distress Scale–Revised was found to be a multidimensional construct. The data obtained confirmed the hypothesis of the factor structure model with a latent second-order variable. Since the convergent and divergent validity of the scale were not confirmed in this study, further assessment is necessary in future studies.

Abstract Background: The presence of psychosocial risks at work is associated with mental and physical health issues in workers. The study aim was to adapt the COPSOQ-ISTAS21 Medium-Version to the Peruvian context and to develop a Short-Version of the instrument.Method: Cross-sectional design study. The COPSOQ-ISTAS21 Medium Version was used. A confirmatory factor analysis was performed to determine the internal structure of each subdimension (first-order) and dimension (second-order) using the Robust Maximum Likelihood estimation method, and classic fit indices in the literature (CFI, SRMR, RMSEA). Internal consistency was evaluated using the alpha and omega coefficients. A short version was developed based on the items with the highest factorial load and that reduce the factorial complexity.Results: A total of 1707 participants were evaluated. In the confirmatory factor analysis, the goodness-of-fit indices for seventeen of the 20 one-dimensional models (subdimensions) were identified; two subdimensions could not be evaluated because they presented only two items. When conducting a multidimensional analysis, we identified that all second-order models presented optimal goodness-of-fit indices, except “psychological demands at work”. The latter required adding four pairs of correlated errors to reach adequate fit values. Finally, a short version of only 31 items was designed from the items with optimal fit indices.Conclusions: The new adapted versions of COPSOQ-ISTAS21 were renamed CENSOPAS-COPSOQ. The CENSOPAS-COPSOQ is an instrument with sufficient evidence of validity and reliability in its medium and short version, which is why its use is recommended in Peruvian work centers to identify the evaluation and prevention of psychosocial risks at work in Peru.
