Comparing Long-Acting Antipsychotic Discontinuation Rates Under Ordinary Clinical Circumstances: A Survival Analysis from an Observational, Pragmatic…
2021
Background Recent guidelines suggested a wider use of long-acting injectable antipsychotics (LAI) than previously, but naturalistic data on the consequences of LAI use in terms of discontinuation rates and associated factors are still sparse, making it hard for clinicians to be informed on plausible treatment courses. Objective Our objective was to assess, under real-world clinical circumstances, LAI discontinuation rates over a period of 12 months after a first prescription, reasons for discontinuation, and associated factors. Methods The STAR Network ‘Depot Study’ was a naturalistic, multicentre, observational prospective study that enrolled subjects initiating a LAI without restrictions …
Feeling physical pain while depressed: The effect of alexithymia
2020
Background: In the literature, depression and alexithymia are associated with greater pain perception. It is unknown whether depression and alexithymia have additive effects on perceived pain. Methods: The present study examined 152 participants (96 women, 56 men). Participants completed the 20-item Toronto Alexithymia Scale, the Hamilton Depression Rating Scale, the Brief Pain Inventory, and the NEO Personality Inventory. There were 49 participants in the active phase of depression with either definite (n = 15) or no alexithymia (n = 34). One hundred three participants showed no depression with either definite (n = 14) or no alexithymia (n = 89). Results: Pain severity showed a small but s…
Resonance of cortico-cortical connections of the motor system with the observation of goal directed grasping movements
2010
Goal directed movements require the activation of parietal, premotor and primary motor areas. In monkeys, neurons of these areas become active also during the observation of movements performed by others, especially for coding the goal of the action (mirror system). Using bifocal transcranial magnetic stimulation (TMS) in healthy subjects, we tested whether the observation of goal directed reach to grasp actions may lead to specific changes in the short-latency connections linking key areas of the mirror system, such as the anterior intraparietal cortex (AIP) and the ventral premotor cortex (PMv), with the primary motor cortex (M1). We found that AIP-M1 and PMv-M1 cortico-cortical interacti…
The PHQ-PD as a screening tool for panic disorder in the primary care setting in Spain
2016
INTRODUCTION Panic disorder is a common anxiety disorder and is highly prevalent in Spanish primary care centres. The use of validated tools can improve the detection of panic disorder in primary care populations, thus enabling referral for specialized treatment. The aim of this study is to determine the accuracy of the Patient Health Questionnaire-Panic Disorder (PHQ-PD) as a screening and diagnostic tool for panic disorder in Spanish primary care centres. METHOD We compared the psychometric properties of the PHQ-PD to the reference standard, the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) interview. General practitioners referred 178 patients who completed the entir…
Fear of Missing Out as a Predictor of Problematic Social Media Use and Phubbing Behavior among Flemish Adolescents
2018
Fear-of-missing-out (FOMO) refers to feelings of anxiety that arise from the realization that you may be missing out on rewarding experiences that others are having. FOMO can be identified as an intra-personal trait that drives people to stay up to date of what other people are doing, among others on social media platforms. Drawing from the findings of a large-scale survey study among 2663 Flemish teenagers, this study explores the relationships between FOMO, social media use, problematic social media use (PSMU) and phubbing behavior. In line with our expectations, FOMO was a positive predictor of both how frequently teenagers use several social media platforms and of how many platforms the…
Self-esteem at school and self-handicapping in childhood: comparison of groups with learning disabilities.
2013
Recent research has focused on the role of self-esteem and self-handicapping strategies in the school domain. Self-handicapping refers to maladaptive strategies employed by adults and children for protection and maintenance of positive school self esteem. In this study the self-esteem and the self-handicapping strategies of children with dyslexia, reading comprehension disabilities, and mathematical disabilities were compared to a control group with normal learning. There were 56 children whose mean age was 8 (23 girls, 33 boys), attending Grade 3 of primary school. These pupils were selected by scores on a battery of learning tests commonly used in Italy for assessment of learning disabil…
Cortical networks of procedural learning: Evidence from cerebellar damage
2007
The lateral cerebellum plays a critical role in procedural learning that goes beyond the strict motor control functions attributed to it. Patients with cerebellar damage show marked impairment in the acquisition of procedures, as revealed by their performance on the serial reaction time task (SRTT). Here we present the case of a patient affected by ischemic damage involving the left cerebellum who showed a selective deficit in procedural learning while performing the SRTT with the left hand. The deficit recovered when the cortical excitability of an extensive network involving both cerebellar hemispheres and the dorsolateral prefrontal cortex (DLPFC) was decreased by low-frequency repetitiv…
Daily Associations between Emotions and Aggressive and Depressive Symptoms in Adolescence: The Mediating and Moderating Role of Emotion Dysregulation
2019
Nearly half of adolescents experience depressive or aggressive symptoms that impair their functioning at some point in adolescence. Experiencing intense difficult emotions and difficulties regulating such emotions may lead to these depressive and aggressive symptoms. However, existing work largely investigates how adolescent emotions at a single time point predict adolescent depressive or aggressive symptoms months or years later. New investigations are needed to capture the dynamic, changing nature of adolescents’ daily experiences of emotions and symptoms of mental distress. Such investigations would further understanding of how emotions affect mental health in adolescents’ everyday lives…
Use of Robotics kits for the Enhancement of Metacognitive Skills of Mathematics: a Possible Approach.
2011
The present study is aimed at analyzing the process of building and programming robots as a metacognitive tool of mathematics. Quantitative data from a study performed on a sample of students attending an Italian secondary school are described. Results showed that robotics activities may be used as a new metacognitive environment allowing students to improve their attitude towards mathematics, and to increase their attitude to reflect on themselves and on their own learning, and their higher-level control components, such as forecasting, planning, monitoring and evaluation exercises and problems related to implementation.
Perceptual commensuration in decision tables
2017
This paper calls attention to design features that could enhance the helpfulness of the decision table to decision makers trying to get a better intuitive grasp of the choices facing them. The experiments reported here show that the grey scale is more facilitative than the number scale for problem comprehension as measured by the identification of dominance and the identification of non-additivity, each of which requires a view of the decision problem that is sensitive to patterns across attributes. Additional design features that could enhance the decision makers’ grasp of the choices facing them are suggested for further research.
