Meaning in life among adolescents: Factorial invariance of the Purpose in Life Test and buffering effect on the relationship between emotional dysreg…
2019
Objective: The purpose of the present study was threefold: first, to analyse the psychometric properties of a 10‐item Spanish version of the Purpose in Life Test, which assesses meaning in life (MiL), in a sample of community adolescents; second, to analyse the differences between the age and gender groups; and third, to analyse whether MiL buffers the relationship between emotional dysregulation and hopelessness. Method: Participants were 1,599 adolescents from 12 to 19 years old, M = 15.69, SD = 2.14. The Purpose in Life Test‐10 Items, the Beck Hopelessness Scale, and the Difficulties in Emotional Regulation Scale were used. Results: A nine‐item version showed good fit, psychometric prope…
Criminological differences between child pornography offenders arrested in Spain.
2019
Abstract Background Lack of studies on CP offenders from non-English speaking countries motivated the analysis of the profile of adult men arrested in Spain for such crimes (N = 347). Objective The current study examined differences between groups of CP users according to their criminal history (i.e., CP-only offenders, CP offenders with other nonviolent or non-sexually violent crimes, and dual offenders). Methods Analyses of case investigation files were performed across seven key areas: (1) sociodemographic characteristics, (2) criminological data, (3) characteristics of index CP offending, (4) characteristics of CP collections, (5) access to children, (6) indication of pedophilic or hebe…
Psychometric properties of measures of sociocultural influence and internalization of appearance ideals across eight countries
2020
The aim of the current study was to examine the psychometric properties of two well-established measures of sociocultural influence and internalization of the thin/low body fat ideal and muscular ideal. Data from 6272 emerging adults (68.9 % female), aged 18-30 years from Australia, Belgium, Canada, China, Italy, Japan, Spain, and the U.S. were included in this study. Participants completed measures of pressure from mother, fathers, peers, and media, to both increase muscles and lose weight, as well as internalization of the thin/low body fat ideal and muscular ideal. Overall, support for partial invariance was found across the scales. In addition, group level differences were found between…
Sign effect in adolescents: Within‐subject comparison of delay discounting of hypothetical monetary gains and losses
2020
The purpose of this article is to contribute to the research on the sign effect, steeper discounting of gains compared to losses, by offering results from an experiment using a "double-delay" procedure on adolescents. Twenty-four 14-year-old schoolchildren completed a computer-based test consisting of choices of Smaller-Sooner (SS) and Larger-Later (LL) hypothetical monetary gains and losses. Within-subject comparison and analysis of the aggregated data were conducted. Current results were also examined in light of prior research with adult participants, and variations in behavioral patterns were identified. Although the sign effect appears to be more profound in adolescents compared to adu…
''Sex-related Trends In Participation and Performance In the 'swiss Bike Masters' From 1994-2012''
2013
Gloor, Roman Urs | Knechtle, Beat | Knechtle, Patrizia | Ruest, Christoph Alexander | Haupt, Samuel | Rosemann, Thomas | Lepers, Romuald; International audience; ''General participation in contests such as ultra-marathons and ultra-triathlons has increased considerably over the past 30 years, especially among women. This study investigated performance trends in the Swiss Bike Masters, one of the first and most prestigious mountain bike, ultra-endurance races in its class, with comparisons of participation and performance trends to similar races. The development of performance in the Swiss Bike Masters held between 1994 and 2012 was investigated by analysing the number of finishers, their ag…
Runners in their forties dominate ultra-marathons from 50 to 3,100 miles
2014
International audience; OBJECTIVES: This study investigated performance trends and the age of peak running speed in ultra-marathons from 50 to 3,100 miles. METHODS: The running speed and age of the fastest competitors in 50-, 100-, 200-, 1,000- and 3,100-mile events held worldwide from 1971 to 2012 were analyzed using single- and multi-level regression analyses. RESULTS: The number of events and competitors increased exponentially in 50- and 100-mile events. For the annual fastest runners, women improved in 50-mile events, but not men. In 100-mile events, both women and men improved their performance. In 1,000-mile events, men became slower. For the annual top ten runners, women improved in…
The age-related performance decline in ultraendurance mountain biking
2013
Haupt, Samuel | Knechtle, Beat | Knechtle, Patrizia | Ruest, Christoph Alexander | Rosemann, Thomas | Lepers, Romuald; International audience; ''The age-related changes in ultraendurance performance have been previously examined for running and triathlon but not mountain biking. The aims of this study were (i) to describe the performance trends and (ii) to analyze the age-related performance decline in ultraendurance mountain biking in a 120-km ultraendurance mountain bike race the Swiss Bike Masters from 1995 to 2009 in 9,325 male athletes. The mean (+/- SD) race time decreased from 590 +/- 80 min to 529 +/- 88 min for overall finishers and from 415 +/- 8 min to 359 +/- 16 min for the top …
''Sex Difference In Open-water Ultra-swim Performance In the Longest Freshwater Lake Swim In Europe''
2013
Eichenberger, Evelyn | Knechtle, Beat | Knechtle, Patrizia | Ruest, Christoph A. | Rosemann, Thomas | Lepers, Romuald | Senn, Oliver; International audience; ''This study examined participation and performance trends in the 26.4-km open-water ultra-swim "Marathon Swim in Lake Zurich," Switzerland. A total of 461 athletes (157 women and 304 men) finished the race between 1987 and 2011. The mean age of the finishers during the studied period was 32.0 +/- 6.5 years for men and 30.9 +/- 7.2 years for women. The mean age of finishers and the age of winners increased significantly across years for both sexes (p 0.05). The swimming time performance remained stable (p > 0.05) for both sexes across …
Effects of a trail running competition on muscular performance and efficiency in well-trained young and master athletes
2010
International audience; To determine the acute effects of a trail running competition and the age-dependent differences between young and master athletes, 23 subjects [10 young (30.5 ± 7 years), 13 master (45.9 ± 5.9 years)] participated in a 55-km trail running competition. The study was conceived as an intervention study compromising pre, post 1, 24, 48 and 72 h measurements. Measurements consisted of blood tests, ergometer cycling and maximal isometric voluntary contractions (MVC). Parameters monitored included MVC, twitch-and M-wave properties, EMG (RMS) of the vastus lateralis, two locomotion efficiency calculations and muscle damage markers in the blood (CK, LDH). Results indicate pos…
Biochemical composition of salivary stones in relation to stone-and patient-related factors
2018
Background Salivary stones are calcified structures most often found in the main duct of the submandibular or parotid salivary gland. They contain of a core surrounded by laminated layers of organic and inorganic material. Material and Methods Submandibular and parotid sialoliths (n=155) were collected at the department of Oral and Maxillofacial surgery of a general hospital between February 1982 and September 2012. The weight of the sialoliths was determined and the consistency was subjectively classified. Subsequently, the biochemical composition of the stones was determined by wet chemical methods or FT-IR spectrometry. Age and gender of the patients were retrieved from their medical rec…
