Stress e Night Eating Syndrome: uno studio di confronto tra un campione di pazienti psichiatrici ambulatoriali e soggetti sani
No full textThe Night Eating Syndrome (NES) is a disorder characterized by the clinical features of morning anorexia,
evening hyperphagia, and insomnia with awakenings followed by nocturnal food ingestion. The core clinical feature appears
to be a delay in the circadian timing of food intake. The diagnosis and early treatment of NES may represent an important
means of prevention for obesity. Aims. The aim of the present study was to determine the vulnerability to develop NES between
a clinical sample of patients with psychiatric disorders and a non clinical sample.We investigated a possible relation
between stress and a dysfunctional eating behaviors as NES.Methods. The Night Eating Questionnaire (NEQ) has been administered
to 147 psychiatric outpatients and to 531 subjects attending the University of L’Aquila. The NEQ is a questionnaire
used to evaluate the prevalence of NES. The sample has been also evaluated through the Stress-related Vulnerability
Scale (SVS) to measure both perceived stress and social support. Results. The 8.2% of patients scored above the diagnostic
cut-off of the NEQ, compared to the 2.1%in the sample of healthy subjects.The majority of patients who had shown NEQ>25
had a diagnosis of major depressive disorder (MDD).The total scores on the NEQ were strongly associated with the SVS total
score and especially with the “lack of social support” subscale. Conclusions. This study shows the increased vulnerability
of NES in the sample of psychiatric patients compared to the sample of healthy subjects. The study further confirms the
strong association between perceived stress, social support, altered eating behaviors and obesityLa Night Eating Syndrome (NES) è un disturbo dell’alimentazione caratterizzato da scarso appetito durante
il giorno, iperfagia serale e insonnia centrale con abbuffate notturne. La sindrome appare collegata a un’alterazione dei ritmi
circadiani nell’assunzione di cibo. La diagnosi e il trattamento precoce della NES potrebbero costituire un importante mezzo
di prevenzione per l’obesità. Scopo. Lo scopo di questo studio è stato quello di determinare la vulnerabilità allo sviluppo
della NES tra un campione di pazienti affetti da disturbi psichiatrici e un campione di soggetti sani.Abbiamo indagato il possibile
ruolo dello stress nella patogenesi di comportamenti alimentari disfunzionali come la NES. Metodi. Il Night Eating
Questionnaire (NEQ) è stato somministrato a 147 pazienti psichiatrici ambulatoriali e a 531 soggetti sani afferenti all’Università
di L’Aquila. Il questionario NEQ è utilizzato per valutare la prevalenza della NES. Il campione è stato inoltre valutato
attraverso la Stress-related Vulnerability Scale (SVS) allo scopo di valutare sia lo stress percepito sia il supporto sociale.
Risultati. L’8,2% dei pazienti ha superato il cut-off diagnostico del NEQ rispetto al 2,1% del campione di soggetti sani. La
maggior parte dei pazienti con NEQ>25 presentava una diagnosi di disturbo depressivo maggiore (DDM). Il punteggio totale
ottenuto al NEQ è significativamente associato con i livelli di stress percepito valutato dalla SVS, in particolare nella sottoscala
“ridotto supporto sociale”.Conclusioni. Questo studio mostra una maggiore vulnerabilità alla NES nel campione dei
pazienti psichiatrici rispetto al campione della popolazione sana. Lo studio inoltre conferma la forte associazione tra stress
percepito, comportamenti alimentari disregolati e obesità
[The Italian version of the Attitudes Chocolate Questionnaire: a validation study]
No full textSUMMARY. Objective. Chocolate consumption has long been associated with enjoyment and pleasure. Popular claims confer
on chocolate the properties of being a stimulant, relaxant, euphoriant, aphrodisiac, tonic and antidepressant. The aim of
our study was to validate and to verify the reliability of the Italian version of the Attitudes to Chocolate Questionnaire
(ACQ) which evaluates different dimensions of chocolate craving experience.Methods. The Italian version ofACQ was administered
to a sample consisting of 1609 adults, recruited among students of the University of L’Aquila and general population.
The subjects also completed the Stress-Related Vulnerability Scale (SVS), which assesses the level of stress and social
support received. Results. This study showed a good degree of stability and internal consistency of the two-factor model, respectively
represented by craving and sense of guilt, in comparison to previous ones. The scoring for both factors resulted
greater in women than in men. Subjects of younger age and with lower Body Mass Index (BMI) achieved higher scores in relation
to the craving dimension, while a positive correlation was observed between age and sense of guilt. Finally the total
scoring at SVS and its subscales resulted significantly interrelated with the two factors. Conclusions. Our study confirms the
validity and the reliability of the Italian version of the two-factors based ACQ scale and strongly underlines the association
between perceived stress and dysfunctional approach to chocolate consumption.RIASSUNTO. Scopo. Il consumo di cioccolato è da sempre associato a piacere e a gratificazione, grazie alle sue proprietà
euforizzanti, rilassanti, afrodisiache, stimolanti e antidepressive. Lo scopo del presente studio è stato quello di testare la validità
e l’attendibilità della versione italiana dell’Attitudes to Chocolate Questionnaire (ACQ) che valuta le dimensioni dell’esperienza
di craving per il cioccolato.Metodo. La versione italiana dell’ACQ è stata somministrata a un campione composto
da 1609 adulti, reclutati tra gli studenti dell’Università dell’Aquila e tra la popolazione generale. I soggetti hanno inoltre
compilato la Stress-Related Vulnerability Scale (SVS) che valuta il livello di stress e di supporto sociale percepito. Risultati.
Questo studio ha mostrato una certa stabilità e una buona consistenza interna del modello a due fattori, craving e senso di
colpa, rispetto al modello originale. Dallo studio è emerso che le donne hanno ottenuto punteggi significativamente superiori
rispetto agli uomini per entrambi i fattori dell’ACQ, craving e senso di colpa. I soggetti con punteggi maggiori rispetto al
fattore craving sono risultati più giovani e con indice di massa corporea (BMI) minore,mentre rispetto al fattore senso di colpa
questa relazione si è dimostrata significativa solo per l’età. Inoltre è emerso che il punteggio totale della SVS e delle rispettive
sottoscale correla significativamente con entrambi i fattori dell’ACQ. Conclusioni. Questo studio conferma la validità
e l’attendibilità della versione italiana dell’ACQ a due fattori ed evidenzia la forte associazione tra stress percepito e approccio
disfunzionale al cioccolato
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
[Health status and access to health services by the population of L'Aquila (Abruzzo Region, Italy) six years after the earthquake]
No full textNatural disasters, such as the earthquake that occurred in the province of L'Aquila in central Italy, in 2009, generally increase the demand for healthcare. A survey was conducted to assess perception of health status an d use of health services in a sample of L'Aquila's resident population, five years after the event, and in a comparison population consisting of a sample of the resident population of Avezzano, a town in the same region, not affected by the earthquake. No differences were found in perception of health status between the two populations. Both groups reported difficulties in accessing specialized healthcare and rehabilitation services
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
