Assessment of patients affected by treatment-resistant depression: findings from a real-world study in Italy
BIOCHRONOLOGY OF SELECTED MAMMALS, MOLLUSCS AND OSTRACODS FROM THE MIDDLE PLIOCENE TO THE LATE PLEISTOCENE IN ITALY. THE STATE OF THE ART
The Authors have elaborated four range charts of mammalian (large and micro), molluscs and fresh-water and brackish ostracodes faunas, for the selected Plio-Pleistocene fossiliferous localities of the Italy. A new Mammal Age (Aurelian) correlatable to late Middle and Late Pleistocene has been defined. Inside this age two Faunal Units (Torre in Pietra and Vitinia) have been defined as characteristic for Early and Middle Aurelian, while no gisements have been chosen for the late Aurelian. Biochronological units are calibrated on magnetostratigraphic and isotopic scales and by radiometric datings.

Assessment of patients affected by treatment-resistant depression: findings from a real-world study in Italy
Biochronology of selected mammals, molluscs and ostracods from the Middle Pliocene to the Late Pleistocene in Italy. The state of the art.
Gli autori hanno elaborato quattro tavole di distribuzione cronologica delle faune a mammiferi (macro e micro), a molluschi e ad ostracodi di acqua dolce e salmastra, prendendo in considerazione i più significativi giacimenti del Plio-Pleistocene della penisola italiana. In questo lavoro viene istituita una nuova Età a Mammiferi (Aureliano) correlabile con la parte superiore del Pleistocene Medio e con il Pleistocene Superiore: di questa età sono state definite due Unità Faunistiche (Torre in Pietra e Vitinia) per l'Aureliano inferiore e medio, mentre nessun giacimento è stato considerato rappresentativo per l'Aureliano superiore. Le unità biocronologiche sono state calibrate con la magnetostratigrafia, con le scale isotopiche dell'ossigeno e attraverso datazioni radiometriche

Dimensionality of the system usability scale among professionals using internet-based interventions for depression: a confirmatory factor analysis
Background
The System Usability Scale (SUS) is used to measure usability of internet-based Cognitive Behavioural Therapy (iCBT). However, whether the SUS is a valid instrument to measure usability in this context is unclear. The aim of this study is to assess the factor structure of the SUS, measuring usability of iCBT for depression in a sample of professionals. In addition, the psychometric properties (reliability, convergent validity) of the SUS were tested.
Methods
A sample of 242 professionals using iCBT for depression from 6 European countries completed the SUS. Confirmatory Factor Analysis (CFA) was conducted to test whether a one-factor, two-factor, tone-model or bi-direct model would fit the data best. Reliability was assessed using complementary statistical indices (e.g. omega). To assess convergent validity, the SUS total score was correlated with an adapted Client Satisfaction Questionnaire (CSQ-3).
Results
CFA supported the one-factor, two-factor and tone-model, but the bi-factor model fitted the data best (Comparative Fit Index = 0.992, Tucker Lewis Index = 0.985, Root Mean Square Error of Approximation = 0.055, Standardized Root Mean Square Residual = 0.042 (respectively χ2diff (9) = 69.82, p < 0.001; χ2diff (8) = 33.04, p < 0.001). Reliability of the SUS was good (ω = 0.91). The total SUS score correlated moderately with the CSQ-3 (CSQ1 rs = .49, p < 0.001; CSQ2 rs = .46, p < 0.001; CSQ3 rs = .38, p < 0.001), indicating convergent validity.
Conclusions
Although the SUS seems to have a multidimensional structure, the best model showed that the total sumscore of the SUS appears to be a valid and interpretable measure to assess the usability of internet-based interventions when used by professionals in mental healthcare
