The hierarchical factor model of ADHD: invariant across age and national groupings?
2011
Attention-Deficit/Hyperactivity Disorder (ADHD) is characterized by problems with attention, impulsivity, and hyperactivity. The diagnosis derives from 18 symptoms indexing these behavioural domains [American Psychiatric Association (APA), DSM-IV-TR, 2000]. There is substantial continuity in maintaining a diagnosis of ADHD from childhood to adolescence (Faraone, Biederman, & Mick, 2006); however the phenotypic expression is highly variable within the diagnosed group and across time (Barkley, 2006; Nigg, 2006). Current diagnostic formulations distinguish between symptoms of inattention and those of hyperactivity-impulsivity. Three ADHD subtypes are recognized in the DSM-IV: the predominantly…
Gender-Dependent Associations of Anxiety and Depression Symptoms With Eating Disorder Psychopathology in a Representative Population Sample
2021
Background:Evidence shows that anxiety and depressive disorders play an important role in eating disorder behavior. However, given the epidemiology of eating disorders, there is a need to investigate potentially gender-specific connections.Method:This study tested the associations of anxiety and depression symptoms with eating disorder symptoms and behaviors and explored whether they differed between men and women. Within a population-representative survey (N= 2,510; ages 14–94), participants completed measures of depression symptoms (PHQ-2), anxiety symptoms (GAD-2), and eating disorder symptoms (EDE-Q8). We conducted linear regression analyses of the EDE-Q8 sum score and General Linear Mo…
Self-image and psychological distress in treatment-seeking adolescents
2017
Background: Adolescence has been recognized as a critical period for mental health during which it is fundamental to the well-being of adolescents to provide early and appropriate mental health interventions. Self-image perceptions play a particularly relevant role during adolescence since individuals are extensively involved in reorganizing their identity and relationships. Although the self-image development implies adaptive outcomes for most adolescents, some age-related tasks can be difficult to deal with and lead to psychological suffering for a minority of them. Method: This study examined how domain-specific self-image was associated with psychological distress in 128 treatment-seeki…
THE RELATIONSHIP BETWEEN FOREIGN LANGUAGE ENJOYMENT AND GENDER AMONG SECONDARY GRAMMAR SCHOOL STUDENTS
2018
In the context of second language acquisition, foreign language enjoyment (FLE) is a relatively new concept. For that reason, none of the few research carried out in the field thus far has been focused on whether gender might be an important determinant of either a high or a low level of FLE. Thus, the purpose of the present paper was to examine the influence of FLE on learning English as a foreign language, as well as to investigate this relationship from the perspective of gender. The results of this study revealed that there are no statistically significant differences between males and females in FLE, while such differences are found in terms of the sources of FLE each gender perceives …
Orientation-invariance of individual differences in three face processing tasks
2019
Numerous studies have reported impairments in perception and recognition, and, particularly, in part-integration of faces following picture-plane inversion. Whether these findings support the notion that inversion changes face processing qualitatively remains a topic of debate. To examine whether associations and dissociations of the human face processing ability depend on stimulus orientation, we measured face recognition with the Cambridge Face Memory Test (CFMT), along with experimental tests of face perception and selective attention to faces and non-face objects in a sample of 314 participants. Results showed strong inversion effects for all face-related tasks, and modest ones for non-…
Analysis of performance and age of the fastest 100-mile ultra-marathoners worldwide
2013
OBJECTIVES: The performance and age of peak ultra-endurance performance have been investigated in single races and single race series but not using worldwide participation data. The purpose of this study was to examine the changes in running performance and the age of peak running performance of the best 100-mile ultra-marathoners worldwide. METHOD: The race times and ages of the annual ten fastest women and men were analyzed among a total of 35,956 finishes (6,862 for women and 29,094 for men) competing between 1998 and 2011 in 100-mile ultra-marathons. RESULTS: The annual top ten performances improved by 13.7% from 1,132±61.8 min in 1998 to 977.6±77.1 min in 2011 for women and b…
Changes in breaststroke swimming performances in national and international athletes competing between 1994 and 2011 -a comparison with freestyle swi…
2014
Abstract Background The purpose of the present study was to analyse potential changes in performance of elite breaststroke swimmers competing at national and international level and to compare to elite freestyle swimming performance. Methods Temporal trends in performance of elite breaststroke swimmers were analysed from records of the Swiss Swimming Federation and the FINA (Fédération Internationale de Natation) World Swimming Championships during the 1994–2011 period. Swimming speeds of elite female and male breaststroke swimmers competing in 50 m, 100 m, and 200 m were examined using linear regression, non-linear regression and analysis of variance. Results of breaststroke swimmers were …
Participation and performance trends in ultra-endurance running races under extreme conditions - 'Spartathlon' versus 'Badwater'
2013
Abstract Background The aim of the present study was to compare the trends in participation, performance and age of finishers in ‘Badwater’ and ‘Spartathlon’ as two of the toughest ultramarathons in the world of more than 200 km of distance. Methods Running speed and age of male and female finishers in Badwater and Spartathlon were analyzed from 2000 to 2012. Age of peak performance and sex difference in running speed were investigated during the studied period. Results The number of female and male finishes increased in Badwater and Spartathlon. Women accounted on average for 21.5% ± 6.9% in Badwater and 10.8% ± 2.3% in Spartathlon. There was a significant increase in female participation …
The Effect of Course Length on Individual Medley Swimming Performance in National and International Athletes
2014
Abstract Effects of course length (25 m versus 50 m) and advances in performance of individual medley swimming were examined for men and women in Swiss national competitions and FINA World Championships during 2000-2011. Linear regression and analysis of variance (ANOVA) were used to analyse 200 m and 400 m race results for 26,081 swims on the Swiss high score list and 382 FINA finalists. Swiss and FINA swimmers of both sexes were, on average, 4.3±3.2% faster on short courses for both race distances. Sex-related differences in swim speed were significantly greater for FINA swimmers competing in short-course events than in long-course events (10.3±0.2% versus 9.7±0.3%, p<0.01), but did no…
Sex and age-related differences in performance in a 24-hour ultra-cycling draft-legal event - a cross-sectional data analysis
2014
International audience; BackgroundThe purpose of this study was to examine the sex and age-related differences in performance in a draft-legal ultra-cycling event.MethodsAge-related changes in performance across years were investigated in the 24-hour draft-legal cycling event held in Schötz, Switzerland, between 2000 and 2011 using multi-level regression analyses including age, repeated participation and environmental temperatures as co-variables.ResultsFor all finishers, the age of peak cycling performance decreased significantly (β = −0.273, p = 0.036) from 38 ± 10 to 35 ± 6 years in females but remained unchanged (β = −0.035, p = 0.906) at 41.0 ± 10.3 years in males. For the annual faste…
