There is a need to explore variations in children’s safety perceptions for different settings (home, school and neighbourhood) and their relationship with subjective well-being (this including satisfaction with safety and satisfaction with life as whole) by comparing a variety of cultural contexts. A further objective is to explore to what extent gender, age group (10 and 12-year-olds) and level of SWB (measured using the SLSS -Student’s Life Satisfaction Scale- and the BMSLSS -Brief Multidimensional Student’s Life Satisfaction Scale) play a role in this prediction. Results obtained through binary logistic models with samples from Spain (n = 2,724), Algeria (n = 2432), South Africa (n = 2192) and Israel (n = 1914), show that children’s perceptions of safety are predicted by their different perceptions and evaluations of school, home and the nearby area. Perceptions of safety in the nearby area and satisfaction with safety (O.R. = 1.080) contribute to predicting higher levels of satisfaction with life as a whole to a greater extent than scores on the SLSS (O.R. = 1.036) and the BMSLSS (O.R. = 1.050) scales. The country participants live in (especially when combined with satisfaction with safety) and, to a lesser extent gender, also make important contributions. The age group they belong to plays a significant role in predicting higher perceptions of safety at home, in the area nearby, at school, and in predicting higher satisfaction with safety. Results open the door to the introduction of specific interventions (e.g. improving parent-child communication, enhancing public spaces for children to play and promoting children’s participation at school), aimed at promoting higher satisfaction with safety and also indirectly at higher satisfaction with life as a whole, on the basis of achieving positive changes of those factors which make the highest contribution.
Although the relationship between cholesterol and mood states (especially anxiety) has been well studied, few researches have included the role of eating styles in this relationship. This study explored the associations among eating styles, negative emotional symptoms, and levels of cholesterol (and other medical variables) in a population with hypertension and overweight or obesity, analyzing the possible mediation mechanisms involved. A cross-sectional study was conducted in 68 adults with hypertension and overweight/obesity, and stepwise multiple regression analysis and mediation analyses were carried out to test the hypothesis that eating styles mediate the relationship between negative emotional symptoms and cholesterol. Several significant correlations among age, anthropometric, medical, and psychological variables (eating styles and negative emotional symptoms) were found. There was a significant indirect effect of anxiety on total cholesterol and LDL cholesterol through emotional eating. Results suggest that emotional eating has a relevant role in the rise in total and LDL cholesterol, acting as a mediator in the relationship between anxiety and cholesterol. This finding could have important implications, since it introduces a new variable in the relationship between emotions and cholesterol and, therefore, changes the way of understanding this relationship, and of treating high cholesterol in a hypertensive sample. 相似文献
“Vast” is a word often applied to environmental terrain that is perceived to have large spatial extent. This judgment is made even at viewing distances where traditional metric depth cues are not useful. This paper explores the perceptual basis of vast experience, including reliability and visual precursors. Experiment 1 demonstrated strong agreement in ratings of the spatial extent of two-dimensional (2D) scene images by participants in two countries under very different viewing conditions. Image categories labeled “vast” often exemplified scene attributes of ruggedness and openness (Oliva & Torralba, 2001). Experiment 2 quantitatively assessed whether these properties predict vastness. High vastness ratings were associated with highly open, or moderately open but rugged, scenes. Experiment 3 provided evidence, consistent with theory, that metric distance perception does not directly mediate the observed vastness ratings. The question remains as to how people perceive vast space when information about environmental scale is unavailable from metric depth cues or associated scene properties. We consider possible answers, including contribution from strong cues to relative depth. 相似文献
The diversity of sexual behaviors is driven by multiple determinants, including physiological, cultural, educational, and sociological factors. However, the definition of sexual behavior profiles has been barely addressed from a comprehensive point of view. We aimed to develop a multidisciplinary questionnaire for defining individual sexual behavior profiles. The questionnaire was developed by a panel of experts with research experience in the fields of urology, gynecology, psychology, anthropology, and sexology. The list of items was defined in a focus group session and was based on four categories—family-oriented, loving, recreational, and functional—resulting from the combination of two axes: traditional versus non-traditional and sexual benefit versus extra-sexual benefit. Real-time Delphi dynamics was used to assign a weight to each question and a bias to the corresponding responses. The final questionnaire included 50 items considered relevant for describing sexual profiles; the final questionnaire was named SEX360. Of the 50 items included in SEX360, 14 were considered essential for computing the final score; 9 of them were associated with 2 categories, 4 of them with 4 categories, and 1 of them with 3. Nine items referred to the category “family-oriented”, 10 to “loving”, 8 to “recreational”, and 9 to “functional”. The weights assigned to each question ranged from 3.00 to 4.33, and the centers of gravity ranged from 1 to 4. The questionnaire proposed shows the existence of a vast diversity of sexual behavior profiles and may serve as a tool for sexual behavior research. 相似文献
There are rising perceptions and concerns about social isolation and the prevalence of loneliness in Western societies and their negative impact on people’s psychological well-being. We report on an ethnographic study conducted in two Catholic contemplative monasteries in Spain, focusing on the nuns’ and monks' voluntary search for solitude. Through in-depth interviews we aimed to explore their conceptualisation and experiences of solitude, the motivations behind their spiritual quest for it, and the benefits and challenges that this choice entailed. An extraordinary human template of searching for solitude emerged: although they lived communally (they were not alone), they actively avoided intimacy and closeness with other members of the community (they strove to feel alone out of their own volition). Human solitude was seen as the necessary condition for achieving perfect closeness with God and was interpreted not as leading to isolation but as a channel to communicate more intimately with God. 相似文献
A one-year follow up study was conducted on a sample of 940 Spanish adolescents aged mostly from 10 to 15 in order to explore the extent to which their subjective well-being (SWB) changes from one year to the next, and whether these changes are the same for both genders regardless of the instrument used to measure SWB. Participants responded to the same four SWB scales twice, with an interval of a year in between. A decrease in the levels of SWB is identified from the years 11–12 onwards, the decrease in girls being more marked. Multiple-item, domain-based scales (Brief Multidimensional Student’s Life Satisfaction Scale and Personal Well-Being Index) are more sensitive than single-item scales (Overall Life Satisfaction and Happiness Taking into Account Overall Life) in detecting this decrease. Implications for the study of SWB are discussed from a developmental perspective. 相似文献
The Unique Minds Program (Stern, Unique Minds Program, 1999) addresses the socio‐emotional needs of children with learning disabilities (LD) and their families. Children and their parents work together in a multiple family group to learn more about LD and themselves as people with the capacity to solve problems in a collaborative way, including problems in family school relationships. This article reports the cultural adaptation of the program for use in Spain and findings from a feasibility study involving three multiple family groups and a total of 15 children and 15 mothers, using a pre‐post design. This Spanish adaptation of the program is called “Mentes Únicas”. Standardized outcome measures indicated an overall statistically significant decrease in children's self‐rated maladjustment and relationship difficulties by the end of the program. Improvements were endorsed by most mothers, although they were not always recognized by the children's teachers. The program had a high level of acceptability: Mothers and children felt safe, understood, and helped throughout the sessions. The efficacy of the adapted intervention for the context of Spain remains to be tested in a more rigorous study. 相似文献
Two surveys were conducted in Chile with indigenous Mapuche participants (N study 1: 573; N study 2: 198). In line with previous theorising, it was predicted that intergroup contact with the non‐indigenous majority reduces prejudice. It was expected that this effect would be because of contact leading to more knowledge about the outgroup, which would then lead to less intergroup anxiety. The two studies yielded converging support for these predictions. 相似文献
