Psychometric evaluation of the Eating Disorders in Youth-Questionnaire when used in adults: Prevalence estimates for symptoms of avoidant/restrictive…
2020
Objective Restrictive eating behaviors occur across ages, but little is known about symptoms of avoidant/restrictive food intake disorder (ARFID), especially in adults. This study sought to examine the prevalence of symptoms of ARFID in the adult population, providing a psychometric evaluation of the Eating Disorders in Youth-Questionnaire (EDY-Q) and population norms. Method In a representative survey of the German population, N = 2,424 adults (1,297 women, 1,127 men; age 49.5 ± 17.5 years) were assessed with the EDY-Q and measures of eating disorder and general psychopathology for divergent validation. Results The point prevalence of self-reported symptoms of ARFID amounted to 0.8% (20/2,…
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…
Habituation and recovery of a slow negative wave of the event-related brain potential.
2002
This study is concerned with the question of whether the late, slow negative wave 2 (SNW2) component of the event-related brain potential is a component of the orienting response (OR). As habituation of the SNW2 would be an argument for such a link with the OR, it was investigated using a variant of the classical repetition/change paradigm. Results supported major claims to be made for a component of the OR: the amplitude of the vertex SNW2 exhibited roughly the typical exponential decline with repeated stimulations (six numeric verbal stimuli presented seriatim in an ascending order) and responded incrementally to a change, at least in a narrow time slot, i.e. it exhibited partial recovery…
Correlates of vibrotactile thresholds in men of different ages
1986
— As a part of a larger gerontological research project vibrotactile thresholds on the inner malleolus of the ankle were studied in 355 men aged 31–35, 51–55 and 71–75 years. The groups studied were random samples of men living in the town of Jyvaskyla in Finland in the year 1981. The thresholds were assessed at three frequencies: 50 Hz, 100 Hz and 250 Hz. The thresholds were associated with age at all frequencies, the means of the threshold values being significantly higher in the older age groups. Within the age groups the thresholds correlated positively with height. In addition, reaction and movement time, leg extension velocity, and postural sway were associated with the thresholds. Ne…
Postural Sway During Standing and Unexpected Disturbance of Balance in Random Samples of Men of Different Ages
1985
Postural sway behavior while standing and during and after an unexpected disturbance of balance was examined in men aged 31 to 35, 51 to 55, and 71 to 75 years. The groups studied were random samples of men living in the town of Jyväskylä in 1981. Postural sway while standing was more pronounced in the older age groups, whereas after a disturbance of balance postural sway was nearly the same in all age groups. The functioning of the postural control system was correlated with the vibratory threshold on the ankles, grip strength, as well as with aerobic and anaerobic capacity within the age groups. Further, in the youngest age group the functioning of the postural control system was poorer a…
Psychophysical evidence for long-term potentiation of C-fiber and Adelta-fiber pathways in humans by analysis of pain descriptors.
2007
Long-term potentiation of human pain perception (nociceptive LTP) to single electrical test stimuli was induced by high-frequency stimulation (HFS) of cutaneous nociceptive afferents. Numerical pain ratings and a list of sensory pain descriptors disclosed the same magnitude of nociceptive LTP (23% increase for >60 min, P < 0.001), whereas affective pain descriptors were not significantly enhanced. Factor analysis of the sensory pain descriptors showed that facilitation was restricted to two factors characterized by hot and burning (+41%) and piercing and stinging (+21%, both P < 0.01), whereas a factor represented by throbbing and beating was not significantly increased (+9%, P = …
Driving on the motorway: the effect of alternating speed on driver's activation level and mental effort
2002
When most of the driving tasks are performed automatically, a driver's level of alertness may decline, as has been pointed out in the study of the phenomenon called 'highway hypnosis'. One possible countermeasure is to periodically vary the speed (Wertheim 1978), but the authors have not found any studies that directly assess the effectiveness of this countermeasure. The objective of our study has been to provide empirical evidence regarding the effects of this strategy on the level of driver activation on a motorway route in real traffic. In the present study activation level as indexed by a relative measure based on slow EEG activity tended to be significantly higher when speed was modifi…
Anaplastic large cell lymphoma (CD30+/Ki-1+). Analysis of 35 cases followed at GISL centres
1995
Between January 1988 and June 1992, 35 patients with primary anaplastic large cell lymphoma (ALCL)CD30+ were referred to one of the institutions participating in GISL (Gruppo Italiano per lo Studio dei Linformi). 16 patients were treated with ProMACE-CytaBOM, two with MACOP-B, one with CHOP and one with LSA2-L2. As of November 1990, all newly diagnosed patients were treated with MOPP/EBV/CAD hybrid. 27 (77%) cases of ALCL CD30+ and 8 (23%) cases of Hodgkin's-related (HR) lymphoma CD30+ were diagnosed. Extranodal disease was present in 22 cases (63%), and 8 patients (23%) had primary bone marrow involvement. Twenty-three complete remissions (CR) (66%), six partial remissions (PR) (17%) and s…
Why Do Forward Maskers Affect Auditory Intensity Discrimination? Evidence from "Molecular Psychophysics"
2014
Nonsimultaneous maskers can strongly impair performance in an auditory intensity discrimination task. Using methods of molecular psychophysics, we quantified the extent to which (1) a masker-induced impairment of the representation of target intensity (i.e., increase in internal noise) and (2) a systematic influence of the masker intensities on the decision variable contribute to these effects. In a two-interval intensity discrimination procedure, targets were presented in quiet, and combined with forward maskers. The lateralization of the maskers relative to the targets was varied via the interaural time difference. Intensity difference limens (DLs) were strongly elevated under forward mas…
Infant information processing and family history of specific language impairment: converging evidence for RAP deficits from two paradigms
2007
An infant's ability to process auditory signals presented in rapid succession (i.e. rapid auditory processing abilities [RAP]) has been shown to predict differences in language outcomes in toddlers and preschool children. Early deficits in RAP abilities may serve as a behavioral marker for language-based learning disabilities. The purpose of this study is to determine if performance on infant information processing measures designed to tap RAP and global processing skills differ as a function of family history of specific language impairment (SLI) and/or the particular demand characteristics of the paradigm used. Seventeen 6- to 9-month-old infants from families with a history of specific l…
