Body mass index is a common proxy for proportion of body fat. However, body mass index may not classify youth similarly across ages and ethnicities. We used sex- and ethnic-specific receiver operating characteristic curves to determine how obesity classifications compared between body mass index and dual energy x-ray absorptiometry-based body fat percent. Male and female participants 9- to 18-years-old (n = 944; 487 female) were measured 1 to 13 times (1999–2012; 4,411 observations). Body mass index identified < 50% of those classified as obese from body fat percent. Specificity was 99.7%, and sensitivity was 35.8%. Using area under the curve and standard error values, body mass index performed significantly better for: Male versus female at 10 years, Asian versus European female except at 13-, 15-, and 16-years-old, Asian female versus male except at 10- and 15-years-old, and for European male versus female, 9- to 11-years-old (p < .05). Our findings provide evidence that users of body mass index should use caution when comparing body mass index across age, sex, and ethnicity. 相似文献

Value orientations and studying in school–leisure conflict: A study with samples from five countries
Manfred Hofer Sebastian Schmid Stefan Fries Ilija Zivkovic Franziska Dietz 《Learning and individual differences》2009,19(1):101-112
The relations between students' value orientations and experiences of motivational interference during studying following conflicts between learning and leisure activities were investigated in a self-report study. Overall, 1075 adolescents, mostly from Catholic schools, in Bosnia–Herzegovina (n = 203), India (n = 200), Paraguay (n = 96), Spain (n = 442), and the US (n = 134), participated. The samples varied substantially in terms of modern and postmodern value orientations, experience of motivational interference during studying, and time invested in studying. By controlling for age, gender, and economic capital, postmodern value orientation was positively related to conflict frequency and experience of motivational interference during learning, and negatively related to time investment. For modern value orientation, the relations were almost reversed. Despite the considerable differences between the sample means, the study revealed some consistency in the relations between the variables across the samples, which indicates that most of the relations can be generalized. 相似文献

Within Hofstede’s framework of individualistic and collectivistic cultures, this contribution examines measurement equivalence of hedonic and eudaimonic entertainment motivations in two different cultures, namely Germany representing a more individualistic culture (N = 180) and Turkey representing a more collectivistic culture (N = 97). By means of a multi-group confirmatory factor analysis, we could secure configural invariance for both hedonic and eudaimonic entertainment motivations across the German and Turkish sample. Metric invariance, however, could only be obtained for hedonic, but not for eudaimonic motivations. Scalar invariance was obtained for neither of the two entertainment motivations. The study points to the importance of equivalence testing when conducting cross-cultural research. 相似文献

Personal Epistemology Research: Implications for Learning and Teaching 总被引：12，自引：0，他引：12
Barbara K. Hofer 《Educational Psychology Review》2001,13(4):353-383
The ideas that individuals hold about knowledge and knowing have been the target of research programs with disparate names, such as epistemological beliefs, reflective judgment, ways of knowing, and epistemological reflection, all of which appear to be a part of a larger body of work on “personal epistemology.” Epistemological perspectives are salient in numerous academic experiences, have been shown to be related to learning in various ways, influence reasoning and judgment throughout our lives, and have implications for teaching. Yet this work has remained outside the mainstream of educational psychology and cognitive development. This paper addresses three main questions: (1) What is personal epistemology research and how is it conceptualized? (2) How are individuals' conceptions of epistemology related to learning and instruction? (3) Given what we know about personal epistemology, what might educators do? Suggestions are also provided for future research and theoretical development. 相似文献

Adolescence is often thought of as a period during which the quality of parent-child interactions can be relatively stressed and conflictual. There are individual differences in this regard, however, with only a modest percent of youths experiencing extremely conflictual relationships with their parents. Nonetheless, there is relatively little empirical research on factors in childhood or adolescence that predict individual differences in the quality of parent-adolescent interactions when dealing with potentially conflictual issues. Understanding such individual differences is critical because the quality of both parenting and the parent-adolescent relationship is predictive of a range of developmental outcomes for adolescents. The goals of the research were to examine dispositional and parenting predictors of the quality of parents' and their adolescent children's emotional displays (anger, positive emotion) and verbalizations (negative or positive) when dealing with conflictual issues, and if prediction over time supported continuity versus discontinuity in the factors related to such conflict. We hypothesized that adolescents' and parents' conflict behaviors would be predicted by both childhood and concurrent parenting and child dispositions (and related problem behaviors) and that we would find evidence of both parent- and child-driven pathways. Mothers and adolescents (N5126, M age513 years) participated in a discussion of conflictual issues. A multimethod, multireporter (mother, teacher, and sometimes adolescent reports) longitudinal approach (over 4 years) was used to assess adolescents' dispositional characteristics (control/ regulation, resiliency, and negative emotionality), youths' externalizing problems, and parenting variables (warmth, positive expressivity, discussion of emotion, positive and negative family expressivity). Higher quality conflict reactions (i.e., less negative and/or more positive) were related to both concurrent and antecedent measures of children's dispositional characteristics and externalizing problems, with findings for control/regulation and negative emotionality being much more consistent for daughters than sons. Higher quality conflict reactions were also related to higher quality parenting in the past, positive rather than negative parent-child interactions during a contemporaneous nonconflictual task, and reported intensity of conflict in the past month. In growth curves, conflict quality was primarily predicted by the intercept (i.e., initial levels) of dispositional measures and parenting, although maintenance or less decrement in positive parenting, greater decline in child externalizing problems, and a greater increase in control/regulation over time predicted more desirable conflict reactions. In structural equation models in which an aspect of parenting and a child dispositional variable were used to predict conflict reactions, there was continuity of both type of predictors, parenting was a unique predictor of mothers' (but not adolescents') conflict reactions (and sometimes mediated the relations of child dispositions to conflict reactions), and child dispositions uniquely predicted adolescents' reactions and sometimes mothers' conflict reactions. The findings suggest that parent-adolescent conflict may be influenced by both child characteristics and quality of prior and concurrent parenting, and that in this pattern of relations, child effects are more evident than parent effects. 相似文献

Many media entertainment products address the fragility of life by portraying the severe illness or death of the protagonist. According to terror management theory, people need to create meaning in their lives when they are reminded of their own mortality, for instance, by engaging in close relationships with others. Meaningful films may provide recipients with an anxiety buffer that helps them to cope with existential fear. The results of an experimental study (N = 130) demonstrated that participants who had been reminded of their mortality appreciated a meaningful movie more and liked the protagonist better when he survived than when he died. Further, participants who viewed the movie in which the protagonist survived did not activate their self-esteem-based anxiety buffer. The results point toward the potential of entertainment to provide internal anxiety buffers and thereby help in coping with self-threatening situations. The findings are discussed in terms of the connections between meaningful media entertainment, coping mechanisms, and viewers’ terror management. 相似文献

The assumption that today’s German students are able to successfully combine synthesis achievement values and well-being values
appears to be overly optimistic when regarded from the perspective of motivational psychology. The results of a qualitative-quantitative
interview study with 25 students indicate that achievement and well-being values may come into conflict in everyday life.
Incentives for achievement and well-being rarely co-occur in the same action domains. Whereas the school context is dominated
by achievement incentives, leisure time is dominated by well-being incentives. Since both achievement and well-being are appreciated
by most students, they should be prone to experience frequent everyday action conflicts. The motivational characteristics
of postdecisional action conflicts are described on the phenomenal level and their possible impairing effects for learning
processes are pointed out. Finally, alternative forms of value synthesis, which might be realized more successfully, are discussed. 相似文献

ABSTRACTA great deal of information and many services can now be accessed digitally. In order to make use of such services, however, it is necessary to have some form of Internet access. A lack of involvement in digital society may produce new forms of social exclusion. Older adults are particularly at risk of Internet-related social exclusion, since they tend to use the Internet less than younger adults. Little is known, however, about whether this lower level of Internet use among older people is in fact accompanied by a sense of social exclusion. In order to investigate the subjective sense of digital social exclusion resulting from a lack of Internet usage, we conducted a secondary analysis of a representative, cross-sectional telephone survey of 1,037 adults aged 65 years and over and living in Switzerland. We found that 33% of “onliners” reported that they would feel socially excluded were they to stop using the Internet, compared with 14% of “onliners” who felt socially excluded on account of their lack of Internet use. Our analyses show that onliners’ attitudes toward Internet use and the variety of online applications available were related to their sense of social exclusion. By contrast, offliners’ attitudes toward Internet use and their feelings of loneliness in general were predictors for their sense of social exclusion as a result of not using the Internet. The results of the study as well as its implications for research and practice are discussed. 相似文献

The aim of this self-report study is to analyze proposed interrelations between value orientations, self-control, frequency of school–leisure conflicts, and life-balance in adolescence. Life-balance is defined as satisfying time investment in different life areas. The tested model posits that self-control is negatively related to conflict frequency and that the latter is negatively related to life-balance. Achievement and well-being value orientations, in turn, should be connected to the degree of self-control and the frequency of goal conflicts. In the study, 817 German 8th-graders with a mean age of 13.4 years participated. Results from structural equation modeling supported the proposed model. The results suggest that fostering self-control can be a promising approach to decrease the frequency of goal conflicts, and thus increase students' experience of life-balance. 相似文献
