Background: Systematic and purposeful study of self-efficacy beliefs of Iranian nurses in the face of occupational stressors requires understanding the importance of studying this issue and then having a suitable tool to measure it in this group. This study aimed to assess the validity and reliability of the short form of Occupational Coping Self-Efficacy for Nurses Scale (OCSE-N) among Iranian...

The purpose of this study was to use confirmatory factor analysis (CFA) to revise the factor structure of the CSAI-2 using one data set, and then to use CFA to validate the revised structure using a second data set. The first data set (calibration sample) consisted of 503 college-age intramural athletes, and the second (validation sample) consisted of 331 intercollegiate (Division I) and inters...

We use Confirmatory Factor Analysis (CFA) to derive a unifying measure of comparison of scientists based on bibliometric measurements, by utilizing the h-index, some similar h-type indices as well as other common measures of scientific performance. We use a real data example from nine well-known Departments of Statistics (Berkeley, Carnegie Mellon, Chicago, Duke, Harvard, Minnesota, Oxford, Sta...

NEO instruments are widely used to assess Big Five personality factors, but confirmatory factor analyses (CFAs) conducted at the item level do not support their a priori structure due, in part, to the overly restrictive CFA assumptions. We demonstrate that exploratory structural equation modeling (ESEM), an integration of CFA and exploratory factor analysis (EFA), overcomes these problems with ...

OBJECTIVE Royall and colleagues identified a latent dementia phenotype, "δ", reflecting the "cognitive correlates of functional status." We sought to cross-validate and extend these findings in a large clinical case series of adults with and without dementia. METHOD A confirmatory factor analysis (CFA) model for δ was fit to National Alzheimer's Coordinating Center data (n = 26,068). Factor s...

Confirmatory factor analysis (CFA) is widely used for examining hypothesized relations among ordinal variables (e.g., Likert-type items). A theoretically appropriate method fits the CFA model to polychoric correlations using either weighted least squares (WLS) or robust WLS. Importantly, this approach assumes that a continuous, normal latent process determines each observed variable. The extent...

The study revisited the community of inquiry (CoI) instrument for construct revalidation. To that end, used confirmatory factor analysis (CFA) to examine four competing models (unidimensional, correlated-factor, second-order factor, and bifactor models) on model fit statistics computed using parameter estimates from a statistical estimator ordinal categorical data. CFA identified as optimal str...

Data from 6 studies (N = 945) were combined to examine the factor structure and construct validity of J. Kuhl's (1994a) measure of action-state orientation, the Action Control Scale (ACS). Initial confirmatory factor analysis (CFA) of 4 models showed poor fit with the data. Items that did not perform well were dropped, and the 4 CFA models were retested, resulting in support for a 3-factor solu...

background: with increasing age, the prevalence of chronic diseases increases. since health‑promoting behaviors (hpb) are considered a basic way of preventing diseases, especially chronic diseases, it is important to assess hpb. this study examines the validity and reliability of the health promoting lifestyle profile ii (hplp‑ii). methods: this is a cross‑sectional study which is conducted on ...

BACKGROUND The Jefferson Scale of Attitudes Toward Physician-Nurse Collaboration (JSATPNC) has been used to measure attitudes regarding nurse-physician collaboration. However, psychometric evaluation is lacking for the nurse practitioner (NP) population. PURPOSE This study details a confirmatory approach in testing the factor analytic structure of the JSATPNC against previously reported struc...
