The current study examined BMI and body image dissatisfaction as predictors of physical and mental health-related quality of life (HRQL) and psychosocial functioning in a sample of 414 undergraduate students (mean age = 21.5, SD = 4.9; mean BMI = 23.6, SD = 5.2). In men and women, higher BMI was correlated with body image dissatisfaction and physical HRQL, but not with any measures of psychosocial functioning, whereas higher body image dissatisfaction was associated with poorer physical HRQL and psychosocial functioning. Furthermore, body image dissatisfaction was observed to mediate the relationship between BMI and physical HRQL in men and women. Interestingly, in this model, higher BMI predicted increased self-esteem. These findings suggest that body image dissatisfaction may be an important target for health interventions. 相似文献

The time-dependent change in photocurrent during illumination has been studied in amorphous arsenic tritelluride (a-As Te ), which is an amorphous 2 3 chalcogenide material with a narrow optical bandgap. No photodegradation in the photocurrent is observed in this material, although photodegradation occurs in most wide-bandgap amorphous chalcogenides. 相似文献

Sleep-related problems are prevalent among the aged. The present study examined the influence of a mentally active or "volitional" lifestyle on the rest-activity cycle, nocturnal sleep, and daytime napping in the healthy elderly. 14 aged individuals with a high Volitional lifestyle (M = 74.1 yr. old) and 14 with a Low Volitional lifestyle (M = 73.0 yr. old) were screened by questionnaires including the Philadelphia Geriatric Center Morale scale and the Self-confidence scale. Their activity levels were monitored by a wrist actigraph system for 14 consecutive days. They were also asked to record daily sleep logs. The total times of nocturnal sleep and daytime napping did not differ between the groups. However, the acrophases of circadian (tau = 24 hr.) and circasemidian (tau = 12 hr.) activity cycles were more advanced in the Low Volitional group. In addition, the High Volitional group took a daytime nap with a better timing than did the Low Volitional group: the former started a nap during the phase in which their activity level was going down, whereas the latter when their activity level was going up. These results suggest that high volitional lifestyle may be related to better rest-activity cycle in the healthy elderly. 相似文献

Fourteen subjects participated in a sleep study designed to document the reliability of measurements of REM-related vaginal blood-flow changes. Several standard sleep parameters were also examined for comparison with vaginal measures. The most reliable vaginal measure was the maximal change in disengorgement for a given REM period averaged across a night of REM periods. The reliability of this measure compared favorably with that of a highly reliable computerized measure of REM density. It is suggested that nocturnal vaginal blood-flow measures have sufficient reliability to be useful in the differential diagnosis of organic and psychogenic sexual dysfunction.This study was supported in part by a training grant to the Department of Clinical Psychology, University of Florida, Gainesville (USPHS532DE07133-02), and a grant from the NIH (USPHSCA26364R073241-29) to the second author. 相似文献

Shyness clinic groups were offered in a university counseling center for adolescents and young adults experiencing discomfort and difficulties in interpersonal relationships. Thirty-four students went through a preassessment and screening procedure. Twenty-three participated fully in the program. The first part of the program focused on anxiety management; the second on assertiveness in social relationships; and the third on development of conversational skills. According to results on preprogram and postprogram self-report inventories, written feedback from participants, and observations of the group leaders, participants improved in social skills and ability to manage anxiety. 相似文献

This study explored methodologies enabling us to hear the “non-narrative” voices of participants in narrative research. Individual semi-structured interviews were conducted with seven Japanese workers with recurring sick leave, and the data were analyzed using thematic analysis (TA) and dialogical narrative analysis (DNA). In narrators' apparently chaotic and fragmented statements, TA identified three divided self-images that remained disconnected: image of present self with a sense of setbacks, image of past self, and image of ideal self. As the last two self-images ceaselessly negate the first, these workers had lost a sense of autonomy and self-confidence. On the other hand, DNA described their desperate endeavors to organize their sick leave experiences by appealing to the typology of the illness narrative; however, this effort remained a failure. Through two qualitative analyses that suspended the premise that each narrative enables the narrator's construction of self, we were able to understand the real status of participants who could not narrate their experiences. The ethical obligation of researchers to respect the “unfinalizability” of narrative and remain open to continuous dialogue is discussed. 相似文献

The stigma of seeking help for mental health issues: mediating roles of support and coping and the moderating role of symptom profile 下载免费PDF全文

A key factor to the prevalence of mental illness might be the disinclination to seek help, perhaps owing to the stigma of mental illness. In two studies, the contribution of severity of depressive symptoms, social support, and unsupport, coping strategies, and salience of psychological versus biological features of depression in relation to perceived self‐ and other‐stigma of help‐seeking for mental health issues were examined. Participants were first year students experiencing a transitional stressor, namely entry to university. Together, the findings point to the contribution of social support and unsupportive interactions, and coping methods to the prediction of perceived stigma of seeking help, but that the framing of mental illness can limit or strengthen these relations. 相似文献

We investigate under what conditions the matrix of factor loadings from the factor analysis model with equal unique variances will give a good approximation to the matrix of factor loadings from the regular factor analysis model. We show that the two models will give similar matrices of factor loadings if Schneeweiss' condition, that the difference between the largest and the smallest value of unique variances is small relative to the sizes of the column sums of squared factor loadings, holds. Furthermore, we generalize our results and discus the conditions under which the matrix of factor loadings from the regular factor analysis model will be well approximated by the matrix of factor loadings from Jöreskog's image factor analysis model. Especially, we discuss Guttman's condition (i.e., the number of variables increases without limit) for the two models to agree, in relation with the condition we have shown, and conclude that Schneeweiss' condition is a generalization of Guttman's condition. Some implications for practice are discussed.Kentaro Hayashi is a visiting Assistant Professor, Department of Mathematics, Bucknell University, Lewisburg PA 17837, and Peter M.

Male mice (N = 34) were individually raised with a castrated male cagemate from 5 to 15 weeks of age. Half of them were subsequently isolated in clean cages for 2 weeks, while the other half were housed in isolation for 2 weeks in cages that had previously housed a strange male. After 14 days of isolation-housing, one subject from each condition was placed into pairs and observed for 30 min in a neutral arena. On the next day, weights of their preputial glands were measured. Males exposed to strange male odors were more likely to be dominant during the 30-min test and to have heavier preputial glands than were males that had been housed in clean cages. 相似文献

The author examined whether children's understanding of lies exhibits developmental trends in the elementary school years. Four story contexts were presented to 51 first-grade students, 44 fourth-grade students, and 58 adults. These stories represented combinations of a protagonist's intention (truthful or deceptive) and the truth of the protagonist's message (true or false). The results showed that adults judged whether these messages were lies by considering the protagonist's intentions. By contrast, approximately 30% of first-grade students and some fourth-grade students did not consider intentions in making judgments, although they appropriately predicted the outcomes of the messages. These results suggest that children in the early elementary school years have a conception of lies different from that of adults, and their conception of lies becomes more sophisticated after middle childhood. 相似文献
