This article presents the preliminary data of the development of a Junior version of the Spanish NEO PI-R (JS NEO), suitable for teenagers from 12 to 17 years of age. From the 240 original English items, 92 were modified or reworded to some degree to make the vocabulary adequate for this age group. The psychometric properties of the JS NEO were investigated in a sample of 2,505 adolescents. Results showed that the adult NEO PI-R factor structure was replicated in the junior version of the inventory. Internal consistency and temporal stability reliabilities of the scales were adequate for most scales. Furthermore, the cross-form correlations between the junior (JS NEO) and the adult (NEO PI-R) scales indicated satisfactory construct validity of the junior version of the inventory.

Background And Aim: An increasing body of research indicates that many adults who stutter (AWS) experience anxiety in social and verbal situations. The Unhelpful Thoughts and Beliefs about Stuttering (UTBAS) scales were developed to assess speech-related anxiety and negative cognitions associated with stuttering. This study aimed to translate the UTBAS into Persian, investigate its psychometric properties for Persian-speaking AWS, and compare the results with previously published UTBAS scores across various cultures.

Although prior studies have examined associations of personality traits with sleep, most have investigated self-reported sleep, been cross-sectional, and focused on younger and middle-aged adults. We investigated associations of personality with actigraphic sleep parameters and changes in sleep in 398 cognitively normal adults aged 40-95 years (M ± SD = 70.1 ± 12.

Background: Using [F]altanserin, a serotonin 2A receptor (5-HTR) antagonist Positron Emission Tomography (PET) tracer, a positive association between cortical 5-HTR binding and the inward-directed facets of neuroticism has been demonstrated in healthy individuals. Psilocybin, a 5-HTR agonist, shows promise for the treatment of depression, reducing neuroticism and mood symptoms potentially via hypothalamic-pituitary-adrenal (HPA) modulation. 5-HTR and neuroticism are both modulated by HPA axis function.

Background: The aim of the present study was to analyse the association between neuroticism (one of the Big Five personality traits) and the most common secondary sensorimotor complications occurring in patients after spinal cord injury (SCI), i.e., muscle spasticity (hypertonia) and pain, and to investigate the associations between neuroticism and the effects of conventional rehabilitation (dynamic parapodium) and those using robotic-assisted gait training (RAGT) in this group of patients.
