HIGHLIGHTS Application of Kronecker product to construct parsimonious structural equation models for multivariate longitudinal data.A method for the investigation of measurement bias with Kronecker product restricted models.Application of these methods to health-related quality of life data from bone metastasis patients, collected at 13 consecutive measurement occasions.The use of curves to fac...

Seismic imaging produces images of contrasts in physical parameters in the subsurface, e.g., velocity or impedance. To build such images, a background model describing the wave kinematics in the earth is necessary. In practice, the structural image and background velocity model are unknown and have to be estimated from the acquired data. Migration velocity analysis deals with estimation of the ...

Extant theory posits well-differentiated dimensions of perceived social support as measured using the Social Provisions Scale (SPS). However, evidence is inconsistent with this multidimensionality perspective, with SPS factor correlations near unity and higher between-factor than within-factor item correlations. This article reports on research investigating the internal structure, gender invar...

The Five-Factor Model Rating Form (FFMRF) provides a brief, one-page assessment of the Five-Factor Model. An important and unique aspect of the FFMRF is that it is the only brief measure that includes scales for the 30 facets proposed by Costa and McCrae. The current study builds on existing validity support for the FFMRF by evaluating its factorial invariance across gender within a sample of 6...

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 ...

The concept of overexcitability, derived from Dabrowski's theory of personality development, offers a promising approach for the study of the developmental dynamics of giftedness. The present study aimed at (a) examining the factorial structure of the Overexcitabilities Questionnaire-II scores (OEQ-II) and (b) testing measurement invariance of these scores across intelligence and gender. A samp...

OBJECTIVE On-going evidence is required to support the validity of inferences about change and group differences in the evaluation of health programs, particularly when self-report scales requiring substantial subjectivity in response generation are used as outcome measures. Following this reasoning, the aim of this study was to replicate the factor structure and investigate the measurement inv...
