A new set of 299 pictures for psycholinguistic studies : French norms for name agreement, image agreement, conceptual familiarity, visual complexity,…
2003
Pictures are often used as stimuli in studies of perception, language, and memory. Since performances on different sets of pictures are generally contrasted, stimulus selection requires the use of standardized material to match pictures across different variables. Unfortunately, the number of standardized pictures available for empirical research is rather limited. The aim of the present study is to provide French normative data for a new set of 299 black-and-white drawings. Alario and Ferrand (1999) were closely followed in that the pictures were standardized on six variables: name agreement, image agreement, conceptual familiarity, visual complexity, image variability, and age of acquisit…
A clinical evaluation of the DSM-5 criteria for Internet Gaming Disorder and a pilot study on their applicability to further Internet-related disorde…
2019
Background and aims Internet Gaming Disorder (IGD) and other Internet-related disorders (IRDs) have become growing health concerns in our today’s lives. Based on defined diagnostic criteria, IGD has been recognized as a condition for further research in the DSM-5; however, other IRDs have been excluded. Since the release of the DSM-5, representativeness and appropriateness of the nine diagnostic criteria have been debated. Although some first evidence has been published to evaluate these criteria, our knowledge is still limited. Thus, the purpose of this study was to provide data on the clinical validity of the DSM-5 criteria for IGD and other types of IRD. We were also interested in exami…
Neural substrates of the interaction of emotional stimulus processing and motor inhibitory control: an emotional linguistic go/no-go fMRI study.
2007
Neural substrates of behavioral inhibitory control have been probed in a variety of animal model, physiologic, behavioral, and imaging studies, many emphasizing the role of prefrontal circuits. Likewise, the neurocircuitry of emotion has been investigated from a variety of perspectives. Recently, neural mechanisms mediating the interaction of emotion and behavioral regulation have become the focus of intense study. To further define neurocircuitry specifically underlying the interaction between emotional processing and response inhibition, we developed an emotional linguistic go/no-go fMRI paradigm with a factorial block design which joins explicit inhibitory task demand (i.e., go or no-go)…
Socio-economic inequalities in mortality due to injuries in small areas of ten cities in Spain (MEDEA Project).
2011
Abstract Objectives To analyse socio-economic inequalities in mortality due to injuries among census tracts of ten Spanish cities by sex and age in the period 1996–2003. Methods This is a cross-sectional ecological study where the units of analysis are census tracts. The study population consisted of people residing in the cities during the period 1996–2003. For each census tract we obtained an index of socio-economic deprivation, and estimated standardized mortality ratios using hierarchical Bayesian models which take into account the spatial structure of the data. Results In the majority of the cities, the geographical pattern of total mortality from injuries is similar to that of the soc…
Validation of the Dutch Eating Behavior Questionnaire (DEBQ) in a sample of Spanish women
2014
Contains fulltext : 124145.pdf (Publisher’s version ) (Closed access) The Dutch Eating Behavior Questionnaire (DEBQ) was developed to measure eating styles that may contribute to or attenuate the development of overweight. It comprises three scales that measure emotional, external and restrained eating. The main goal of this study is to evaluate the internal structure of the Spanish version of the DEBQ using updated psychometric techniques in a sample of women. A sample of 647 Spanish females answered the questionnaire. Both exploratory structural equation modeling and confirmatory factor analysis were used to evaluate the factor structure of the DEBQ. Reliabilities were estimated with Cron…
Reliability, Validity, and Factor Structure of the Maladaptive Daydreaming Scale (MDS–16) in an Italian Sample
2019
Maladaptive daydreaming (MD) is an extensive fantasy activity that replaces human interaction and interferes with work and interpersonal functioning. In this study, we investigated the nomological network of the MD construct and examined the psychometric properties of the Maladaptive Daydreaming Scale (MDS-16) in an Italian sample. The MDS-16 is a self-report measure composed of 16 items designed to assess MD. Participants in this study were 468 individuals (333 volunteers, 56.8% female; 135 self-diagnosed maladaptive daydreamers, 78.5% female) between 18 and 56 years of age. MDS-16 scores showed good internal reliability. An exploratory factor analysis suggested a 2-factor solution (interf…
Spanish Adaptation and Validation of the Short Internalized Homonegativity Scale (SIHS)
2016
Internalized homophobia has been related to mental health problems and sexual risk behaviors among nonheterosexual people. This article validates the Spanish adaptation of the Short Internalized Homonegativity Scale (SIHS). For this purpose, 347 men and 183 women completed the instrument. Exploratory factorial analysis showed three factors: public identification as homosexual (PIH), sexual comfort with homosexual people (SEXC), and social comfort with homosexual people (SOCC). These factors explained 57.96% of total variance. In addition, confirmatory factorial analysis supported this structure and internal consistency (Cronbach's alpha) was.80 for the full scale. The three subscales ranged…
Development and validation of the Barriers to Physical Activity and Sport Questionnaire for lesbian, gay, bisexual, transgender and queer/questioning…
2020
Abstract Objective The objective of the study was to develop the Barriers to Physical Activity and Sport Questionnaire for lesbian, gay, bisexual, transgender and queer/questioning (BPASQ-LGBTQ+ [encompassing all spectrums of sexuality and gender]) persons (BPASQ-LGBT), which measures barriers using a socio-ecological model, and to validate it through exploratory and confirmatory factor analysis. Study design Validation study. Methods First, content validity was achieved by (a) developing a bank of items, (b) discussing the adequacy of the items in a committee of experts and classifying the selected ones under three socio-ecological levels (intrapersonal, interpersonal, environmental) and (…
Speech- and sound-segmentation in dyslexia: evidence for a multiple-level cortical impairment
2006
Developmental dyslexia involves deficits in the visual and auditory domains, but is primarily characterized by an inability to translate the written linguistic code to the sound structure. Recent research has shown that auditory dysfunctions in dyslexia might originate from impairments in early pre-attentive processes, which affect behavioral discrimination. Previous studies have shown that whereas dyslexic individuals are deficient in discriminating sound distinctions involving consonants or simple pitch changes, discrimination of other sound aspects, such as tone duration, is intact. We hypothesized that such contrasts that can be discriminated by dyslexic individuals when heard in isolat…
The Influence of Chitosan on the Oral Bioavailability of Acyclovir-a Comparative Bioavailability Study in Humans
2015
Purpose The effects of chitosan hydrochloride on the oral absorption of acyclovir in humans were studied to confirm the absorption enhancing effects reported for in vitro and rat studies, respectively. Methods A controlled, open-label, randomized, 3-phase study was conducted in 12 healthy human volunteers. Zovirax 200 mg dispersible tablets co-administered with doses of 400 and 1000 mg chitosan HCl were compared with Zovirax only. Results The expected increased absorption of acyclovir was not observed. On the contrary, mean area under the plasma concentration-time curve (AUC0-12 h) and maximal plasma concentration (Cmax) decreased following concomitant chitosan intake (1402 versus 1017 and …
