Adjustment disorder as proposed for ICD-11: Dimensionality and symptom differentiation

2014

Although Adjustment Disorder as a diagnostic category is widely used in clinical practice it is critically discussed that it has not been conceptualized as a category with unique symptoms. Hence, the conceptualization of Adjustment Disorder is subject to substantive change in ICD-11 including core symptoms and additional features in a uni-faceted concept. Adjustment Disorder was assessed with a self-rating instrument in a representative sample of the German general population (N=2512). Confirmatory factor analyses (CFA) were applied to test the dimensionality of symptoms according to the new diagnostic concept. Latent class analysis (LCA) was applied to test whether there are distinguishabl…

Reliability and factor structure of the Finnish version of the Sport Imagery Questionnaire.

2006

The aim of this study was to examine the reliability and factor structure of the Finnish version of the Sport Imagery Questionnaire, a measure which examines cognitive and motivational functions of imagery. The final sample comprised 231 participants drawn from 34 sports and ranging in age from 14 to 49 years ( M = 20.9, SD= 5.8). Internal consistency and confirmatory factor analyses were undertaken to evaluate the reliability and factorial validity of the scale. Fit indices and modification data generated from examining the 30-item five-factor model were equivocal, suggesting minor amendment and recategorization of several items rather than major adjustment to the proposed latent factor s…

Reliability and validity of the Digigraph 100 in orthodontic diagnosis.

2001

Cephalometric analyses of lateral cephalograms allow important statements to be made on diagnosis and treatment planning. Such radiographs should, however, be taken with a considerable reduction in radiation exposure. With the Digigraph 100 (Dolphin Imaging Systems Inc., USA) a cephalometric technique based on distance measurements of emitted sonic signals is now available. This study was aimed at determining the degree to which this procedure can cope with the requirements of reliability and validity in the field of orthodontics. For this purpose 50 volunteers were examined by conventional cephalometry with manual tracing of lateral cephalograms as well as by sonic cephalometry, with Jarab…

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…

Peginterferon-Α_2B plus ribavirin is more effective than peginterferon-Α_2A plus ribavirin in menopausal women with chronic hepatitis C.

2012

Under-enrolment of women to randomized clinical trials, including chronic hepatitis C, has long been recognized. The aim of this study was to identify factors predictive of sustained virological response (SVR) to PEG IFN/Ribavirin antiviral therapy in relation to gender and reproductive status of female patients involved. Seven hundred and forty-six treatment-naïve patients (431 men, 315 women) treated with Peg-IFNα-2a (180 μg/week) or Peg-IFNα-2b (1.5 μg/kg/week) plus ribavirin (800–1400 mg/day) for 24 or 48 weeks were studied between 2006 and 2010. Differences in SVR rate, overall and by gender were assessed after adjustment and propensity score matching. SVR was obtained in 44.2% of Peg-…

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…
