Decomposing the True Score Variance in Rated Responses to Divergent Thinking-Tasks for Assessing Creativity: A Multitrait-Multimethod Analysis.

It is shown how the Correlated Traits Correlated Methods Minus One (CTC(M - 1)) Multitrait-Multimethod model for cross-classified data can be modified and applied to divergent thinking (DT)-task responses scored for miscellaneous aspects of creative quality by several raters. In contrast to previous Confirmatory Factor Analysis approaches to analyzing DT-tasks, this model explicitly takes the cross-classified data structure resulting from the employment of raters into account and decomposes the true score variance into target-specific, DT-task object-specific, rater-specific, and rater-target interaction-specific components. This enables the computation of meaningful measurement error-free relative variance-parameters such as trait-consistency, object-method specificity, rater specificity, rater-target interaction specificity, and model-implied intra-class correlations.

Latent Reciprocal Engagement and Accuracy Variables in Social Relations Structural Equation Modeling.

The social relations model (SRM) is the standard approach for analyzing dyadic data stemming from round-robin designs. The model can be used to estimate correlation-coefficients that reflect the overall reciprocity or accuracy of judgements for individual and dyads on the sample- or population level. Within the social relations structural equation modeling framework and on the statistical grounding of stochastic measurement and classical test theory, we show how the multiple indicator SRM can be modified to capture inter-individual and inter-dyadic differences in reciprocal engagement or inter-individual differences in reciprocal accuracy.

Is your stress my stress? A standardized, randomized-controlled paradigm to study physiological stress contagion based on direct stress observation.

Background & Objectives: Existing research indicates that not only own stress leads to physiological stress reactions, but also observing stress in others. So far, a standardized paradigm to reliably induce physiological stress contagion based on direct face-to-face stress observation compared to an active placebo-stress observing control condition is lacking. Here, we tested a standardized randomized placebo-controlled experimental paradigm to investigate physiological reactivity to direct stress observation and characterized the stress contagion response of the major endocrine stress systems, including full reactivity kinetics.

A correlated traits correlated (methods - 1) multitrait-multimethod model for augmented round-robin data.

We didactically derive a correlated traits correlated (methods - 1) [CTC(M - 1)] multitrait-multimethod (MTMM) model for dyadic round-robin data augmented by self-reports. The model is an extension of the CTC(M - 1) model for cross-classified data and can handle dependencies between raters and targets by including reciprocity covariance parameters that are inherent in augmented round-robin designs. It can be specified as a traditional structural equation model.

Recall bias of students' affective experiences in adolescence: The role of personality and internalizing behavior.

Introduction: Adolescence is characterized by multiple biopsychosocial changes, associated with a high intraindividual variability of emotional experiences. Previous findings suggest that this intraindividual variability is reflected in a recall bias of adolescents' emotion reports. However, corresponding findings are scarce and inconclusive.

Estimating and investigating multiple constructs multiple indicators social relations models with and without roles within the traditional structural equation modeling framework: A tutorial.

The present contribution provides a tutorial for the estimation of the social relations model (SRM) by means of structural equation modeling (SEM). In the overarching SEM-framework, the SRM without roles (with interchangeable dyads) is derived as a more restrictive form of the SRM with roles (with noninterchangeable dyads). Starting with the simplest type of the SRM for one latent construct assessed by one manifest round-robin indicator, we show how the model can be extended to multiple constructs each measured by multiple indicators.

The influence of psychosocial and sexual wellbeing on quality of life in women with differences of sexual development.

Background: Previous research indicating that women with differences of sexual development (DSD), namely women with Turner syndrome (TS), women with congenital adrenal hyperplasia (CAH), and women with XY-DSD, have an impaired psychosocial and sexual well-being and quality of life (QOL), was often limited by small samples and inadequate control groups (CGs). Only few studies analysed which psychosocial and sexual factors influence QOL in women with DSD and no study so far has examined whether the DSD-condition itself and the diagnostic group to which they belong moderate this influence.

Methods: We compared 301 women with TS, 221 women with CAH and 142 women with XY-DSD with 603 non-DSD women regarding depression, anxiety, self-esteem, attention deficit hyperactivity disorder, autism, social participation, body acceptance, relationship status, sexual satisfaction and QOL.

Rosy or blue? Change in recall bias of students' affective experiences during early adolescence.

Changes in the quality of emotional experience are among the various significant developmental challenges that characterize early adolescence. Although retrospective and momentary emotional self-reports are known to differ, adolescents' emotional experiences are mainly assessed retrospectively without knowing if the recall is biased in a positive or negative way. The present study extends research on recall bias by investigating possible changes in retrospection effects of students' affective experiences during early adolescence.

Introducing a Computerized Figural Memory Test Based on Automatic Item Generation: An Analysis With the Rasch Poisson Counts Model.

An automatic item generator for figural memory test items called was developed. It is available in . A cognitive model allowed the generation of hypothetically parallel items within three difficulty levels determined by visual information load.

Psychosocial well-being and quality of life in women with Turner syndrome.

Background: Turner syndrome (TS) affects approximately one out of 2500 females. Previous research indicates that women with TS experience impairment in several psychosocial domains as well as in quality of life (QoL). Data, however, mainly focus on girls, whereas data on adult women is extremely scarce, inconsistent and mainly low in sample size.

The Impact of Situational Test Anxiety on Retest Effects in Cognitive Ability Testing: A Structural Equation Modeling Approach.

When a cognitive ability is assessed repeatedly, test scores and ability estimates are often observed to increase across test sessions. This phenomenon is known as the retest (or practice) effect. One explanation for retest effects is that situational test anxiety interferes with a testee's performance during earlier test sessions, thereby creating systematic measurement bias on the test items (interference hypothesis).
