The current paper describes and illustrates three things: (a) sampling variance and confidence intervals for Cronbach’s Alpha, (b) the relative precision of reliability estimates from local studies and meta-analyses, and (c) how to blend the local and metaanalytic information to create an optimal local reliability estimate according to Bayesian principles. The paper is not about artifact correc...

objective: to determine the effectiveness of counseling in reducing anxiety of nulliparous pregnant women. materials and methods: in this quasi-experimental study, 110 nulliparous pregnant women were selected out of all pregnant women referring to fatemieh hospital in hamadan, iran. then, the subjects were divided into two groups in experimental and control (55 women in each). the data were col...

Background and aims This study focuses on the use of popular information and communication technologies (ICTs) by adolescents: the Internet, mobile phones, and video games. The relationship of ICT use and experiential avoidance (EA), a construct that has emerged as underlying and transdiagnostic to a wide variety of psychological problems, including behavioral addictions, is examined. EA refers...

The present study examined whether trait anxiety and trait anger are associated with vulnerability to emotional eating, particularly among obese individuals. Lean (n = 37) and obese (n = 24) participants engaged in a laboratory study where they completed measures of trait anxiety and trait anger at screening and then completed 3 counterbalanced experimental sessions involving different mood ind...

The single-species Continuously Stable Strategy (CSS) and Neighborhood Invader Strategy (NIS) concepts, originally developed as intuitive stability conditions for the evolution of the average trait of a monomorphic population (known as the adaptive dynamics approach), are shown to be relevant for dynamic stability of coevolutionary systems with finitely many traits parameterized by points in a ...

Can event-related electro-encephalogram (EEG) responses provide support for the occurrence of spontaneous trait inferences (STI)? Participants read sentences describing the behavior of a target person from which a strong trait could be inferred. The last word of each sentence determined the consistency with the trait induced during an introductory paragraph. In comparison with sentences that we...

A discrete-time population model in which individuals are distributed over a discrete phenotypic trait-space is studied. It is shown that, for an irreducible mutation matrix , if mutation is small, then an interior equilibrium exists, that is globally asymptotically stable in , while for arbitrary large mutation each trait persists uniformly. For the model reduced to only two traits, conditions...
