This study evaluated dietary habits of Northern Irish men who are at high risk of cardiovascular disease, stratified as never-, ex-, moderate-, or heavy-smokers. Participants were male volunteers (30 - 49 years) from a single workforce in Belfast (n = 765)...
Abstract. To assess the association of dietary patterns and bone mineral density (BMD), 340 healthy Iranian adults (mean age 41.5 ± 7.7 y; 79.1% female) participated in this cross-sectional study. Lumbar spine and femoral neck BMDs were ...
Studies on the reliability, validity, and factor structure of a German version of the Child Behavior ChecklistAbstract. The aim of the present investigation was to test the reliability and validity of a German version of the CBCL (Achenbach & Edelbrock, ...
Disclosure of Grief Questionnaire (DGQ): Development and Validation of a Questionnaire to Assess Communication Patterns After BereavementAbstract. Disclosure of emotional burdensome experiences is important for processing these experiences as well as for ...
Background: Suicide in schizophrenia is a serious problem – ideation rates go up to 40%, and approximately one half of patients attempt suicide at least once. The distinction between attempters and ideators is vital in everyday clinical practice. Aim: To ...
This study analyzed the developmental trends of brain rhythms in a group of children and a group of young adults. Principal component analysis (PCA), ANOVA, as well as correlational and topographical analyses were applied to the power spectral density of ...
Abstract. Threat-related attention bias is thought to contribute to the development and maintenance of anxiety disorders. Dot-probe studies using event-related potentials (ERPs) have indicated that several early ERP components are modulated by ...
Abstract. The objective of this study is to propose a preliminary comprehensive dimensional model of the Rorschach Comprehensive System (RCS). Three European adult nonpatient samples of the RCS were combined (Belgium, France, and Finland, ...
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 ...
When Tucker's congruence coefficient is used to assess the similarity of factor interpretations, it is desirable to have a critical congruence level less than unity that can be regarded as indicative of identity of the factors. The literature only reports ...
Abstract. When principal component solutions are compared across two groups, a question arises whether the extracted components have the same interpretation in both populations. The problem can be approached by testing null hypotheses ...
Abstract. In this paper a profile analysis that utilizes principal component analysis (PCA) is introduced. Although PCA is popular for a dimension reduction method, it is not well known that unrotated components algebraically are summative ...
Abstract. It is challenging to apply exploratory factor analysis (EFA) to event-related potential (ERP) data because such data are characterized by substantial temporal overlap (i.e., large cross-loadings) between the factors, and, because ...
