Validating measurement tools for mentalization, emotion regulation difficulties and identity diffusion among Finnish adolescents

Mentalization, emotion regulation, and identity diffusion are theoretically and clinically important transdiagnostic psychological constructs that contribute to mental health. In order to advance meaningful empirical research on these constructs, we need measures that are well tested. In this study, we used confirmatory factor analysis to assess the reliability and construct validity of the Mentalization Questionnaire (MZQ), different versions of the Difficulties in Emotion Regulation Scale (DERS), and the Assessment of Identity Development and Identity Diffusion in Adolescence (AIDA) with data from a general population of Finnish adolescents (N = 360). For MZQ, the factor structure and validity of the subscales were not confirmed. For DERS, a short version, that did not include the lack of emotional awareness subscale was the most coherent and recommendable version of the measure, with a good degree of reliability and a reasonable indication of the convergent and discriminative validity between the subscales. For AIDA, the factor structure was confirmed, but when using this measure for research purposes, it should be taken into account that reverse coding items may affect the factor structure by creating a method factor. The reliability of the AIDA was acceptable, but some of the subscales showed poor convergent and discriminative validity.Peer reviewe

NEXAFS Sensitivity to Bond Lengths in Complex Molecular Materials: A Study of Crystalline Saccharides

Detailed analysis of the C K near-edge X-ray absorption fine structure (NEXAFS) spectra of a series of saccharides (fructose, xylose, glucose, galactose, maltose monohydrate, α-lactose monohydrate, anhydrous β-lactose, cellulose) indicates that the precise determination of IPs and σ* shape resonance energies is sensitive enough to distinguish different crystalline saccharides through the variations in their average C–OH bond lengths. Experimental data as well as FEFF8 calculations confirm that bond length variations in the organic solid state of 10–2 Å can be experimentally detected, opening up the possibility to use NEXAFS for obtaining incisive structural information for molecular materials, including noncrystalline systems without long-range order such as dissolved species in solutions, colloids, melts, and similar amorphous phases. The observed bond length sensitivity is as good as that originally reported for gas-phase and adsorbed molecular species. NEXAFS-derived molecular structure data for the condensed phase may therefore be used to guide molecular modeling as well as to validate computationally derived structure models for such systems. Some results indicate further analytical value in that the σ* shape resonance analysis may distinguish hemiketals from hemiacetals (i.e., derived from ketoses and aldoses) as well as α from β forms of otherwise identical saccharides
