How does the quality of surveys for nutrient intake adequacy assessment compare across Europe? A scoring system to rate the quality of data in such s…
2009
Research was conducted within the EURopean micronutrient RECommendations Aligned (EURRECA) Network of Excellence, to find the best practice in assessing nutrient intakes. Objectives include: to search for and use data on individual nutrient intake adequacy (NIA) assessment collected in twenty-eight European countries and the four European Free Trade Association countries; to design and test innovative tools for data quality analysis. The information was obtained using the method described by Blanquer et al. in the present issue. The best-practice criteria were devised to select the most appropriate survey in each country. Then a survey quality scoring system was developed in consultation wi…
That Man Behind the Curtain: Investigating the Sexual Online Dating Behavior of Men Who Have Sex With Men but Hide Their Same-Sex Sexual Attraction i…
2016
This study investigates how men who have sex with men (MSM) use chat and dating sites based on theories of stigma-related offline behavior and online self-disclosure. We hypothesize that hidden MSM (those who self-label as heterosexual or who hide their same-sex sexual attraction from family, friends, acquaintances, or a female romantic partner) differ from open MSM in how they behave on gay chat and dating sites and in offline gay venues. Drawing on a survey of 12,002 MSM, we show that hidden MSM tend to mask their identity on gay chat and dating sites while avoiding offline gay venues. They also focus more strongly on online sexual activities (e.g., masturbating during online chats) when …
The Prevalence and Gratification of Nude Self-Presentation of Men Who Have Sex with Men in Online-Dating Environments: Attracting Attention, Empowerm…
2017
This study builds on research about the importance of body presentation among men who have sex with men (MSM) by exploring the phenomenon of nude body presentation in online dating environments. In a quantitative survey of N = 9,235 MSM users of a gay online dating site (ODS) in Germany, the prevalence of nude pictures and gratifications sought while displaying them were investigated. About two-thirds of the participants declared that they use nude pictures in their dating profiles, with only small differences in prevalence between members of different ages, education levels, and sexual orientation. Furthermore, the results indicate that the use of nudity is driven by three underlying grati…
Dopamine D2/D3 receptor availability and venturesomeness.
2011
The construct of impulsivity is considered as a major trait of personality. There is growing evidence that the mesolimbic dopamine system plays an important role in the modulation of impulsivity and venturesomeness, the two key components within the impulsivity-construct. The aim of the present study was to explore an association between trait impulsivity measured with self-assessment and the dopaminergic neurotransmission as measured by positron emission tomography (PET) in a cohort of healthy male subjects. In vivo D2/D3 receptor availability was determined with [(18)F]fallypride PET in 18 non-smoking healthy subjects. The character trait impulsivity was measured using the Impulsiveness-V…
Self-Reported versus Measured Height, Weight and Body Mass Index in Spanish Mediterranean Teenagers: Effects of Gender, Age and Weight on Perceptual …
2002
<i>Background:</i> To have a good physical appearance is a determining factor by which adolescents show a tendency to worry excessively about their weight. The aim of this work is to study the possible relationship between actual and perceived body weight, how it is considered and what strategies are followed for weight control among adolescents residing in Valencia. <i>Methods:</i> A sample of 568 students, 325 girls and 243 boys, aged 14–20 years, were selected from public high schools in Valencia. Their height and weight were used to calculate their actual body mass index (BMIO). The subjective perception of their physical measurements (BMIS) was evaluated by mean…
The “Mainzer EMF-Wachhund”: results from a watchdog project on self-reported health complaints attributed to exposure to electromagnetic fields
2006
The "Mainzer EMF-Wachhund," a watchdog project, offered a system of self-notification of health complaints attributed to exposures to electromagnetic fields (EMFs) to a population of a part of Germany with about 4 million inhabitants. By using a self-administered questionnaire, which was provided online and for download from the Internet, 192 persons reported such health complaints in the period from October 2003 to March 2005. Of these, 56% classified themselves as electromagnetic hypersensitive (EH). Predictors of this self classification were being affected by all kinds of EMF rather than single EMF sources and being female. On average, EH subjects reported a high degree of suffering, 77…
Associations between self-estimated and measured physical fitness among 40-year-old men and women
2005
The aim was to evaluate whether 40-year-old men and women are able to estimate their level of fitness compared with actual measured physical fitness. Twenty-nine men and 35 women first completed a questionnaire at home and then their physical fitness was measured at laboratory. The index of self-estimated physical fitness was calculated by summing up the scores of self-estimated endurance, strength, speed and flexibility. The index of self-estimated endurance was calculated by summing up the scores of self-estimated endurance and those of the self-estimated distance they could run, cycle, ski and walk. The index of measured physical fitness was calculated by summing up the z-scores of a sub…
Hypogonadism-related symptoms: development and evaluation of an empirically derived self-rating instrument (HRS ‘Hypogonadism Related Symptom Scale’)
2009
While self-report screening instruments are highly sensitive to hypogonadism in the ageing male, they have lacked specificity as evidenced by low or absent correlations with testosterone. The purpose of this paper was to develop an economical and specific screening instrument for identifying hypogonadal ageing men. Based on a comprehensive study of physical, somatoform and affective complaints, sexual behaviour and function and hormonal parameters of 263 outpatients aged 40 years and above (M = 56.2; 40-84 years) recruited from six andrological outpatient departments in Germany, we identified those items correlating significantly with testosterone. By factor analyses, five factors were iden…
Sense of coherence, academic performance and professional vocation in Certified Nursing Assistant students
2019
BACKGROUND: The sense of coherence (SOC) of the salutogenic health model explains why people in stressful situations are able to maintain or even improve their health. There are some studies on which measures are more effective to reduce stress in Nursing assistant students. There are no studies that link SOC with the two key aspects in the prevention of stress in Nursing assistant students: the motivation of pursuing this profession and the academic level. OBJECTIVES: To explore the salutogenic paradigm among Nursing assistant students in a region of Spain (Comunitat Valenciana). DESIGN: Cross-sectional, analytical and exploratory study carried out in 2016. METHODS: Students of the first y…
Induced not just right and incompleteness experiences in OCD patients and non-clinical individuals: An in vivo study
2016
Abstract Background and objectives Research on incompleteness and not-just right experiences, (INC/NJREs) indicate that some OCD symptom dimensions are motivated by these experiences rather than by anxiety. Most published data are correlational, using non-clinical individuals. This study sought to examine INC/NJREs in vivo in non-clinical and OCD individuals. Methods Study 1: Ninety-three undergraduates were randomly assigned to a INC/NJREs induction (n=44) or non-induction task (n=47). Scores on self-reports assessing INC, NJREs, OCD, Anxiety, and Depression were also recorded. Study 2: Twenty adults with OCD performed the induction task and completed the same questionnaire-packet as the n…
