Reverse worded (RW) items are often used to reduce or eliminate acquiescence bias, but there is a rising concern about their harmful effects on the covariance structure of the scale. Therefore, results obtained via traditional covariance analyses may be distorted. This study examined the effect of the RW items on the factor structure of the abbreviated 18-item Need for Cognition (NFC) scale usi...

Rho factor is a hexameric ring-shaped helicase which terminates transcription in Escherichia coli. Two recent crystal structures of Rho in complex with nucleic acid reveal how this helicase ring loads onto mRNA and encircles it.

today, there are many concepts such as a sense of place and attachment to place presented in architecture and urban literature in the field of environmental studies. meanwhile, relationship between the two is not much explained. this study defines the concept of sense of place and attachment to place and the factors influencing them followed by providing a four- dimensional model derived from s...

The purpose of this study was to examine the psychometric properties of a Spanish version of the Bulimia Test-Revised (BULIT-R). The goal was to test the factor-structure equivalence of the BULIT-R across two samples of college students from two different cultures, Spain and the US. Researchers using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) have reported differen...

a combination of elements is usually used in reconnaissance geochemical exploration and distribution maps are drawn to identify probable anomalies. in this study, 102 stream sediment samples from the arid environment of mesgaran area, eastern iran, were investigated using r-mode factor analysis. a four-factor model with a cumulative variance of 75.90% clearly indicated group associations of the...

Background and Aim: The prevalence and increase of suicidal ideation and attempts among young people and students have been one of the concerns of researchers and mental health care professionals. The present study evaluated the psychometric properties of the Persian version of Reasons for Living for Young Adults-II (RFL-YA-II) in a group of Iranian students. Procedure: This study was conducted...

BACKGROUND The Well-being Questionnaire (W-BQ) has been designed to measure psychological well-being in people with a chronic somatic illness and is recommended by the World Health Organization for widespread use. However, studies into the factor structure of this instrument are still limited and their findings are inconsistent. This study aimed to investigate the factor structure of the Dutch ...

The factor structure of the Velicer Attitudes Toward Violence Scale [VATVS; Velicer, Huckel and Hansen, 1989] was examined in three studies. Study 1 (n5 460 undergraduates) found a poor fit for a hierarchical five-factor model earlier advanced by Velicer et al. [1989], but a good fit for an oblique four-factor model. In Study 2, this alternative model was cross-validated in a confirmatory facto...
