Support for the uniqueness of body dissatisfaction from drive for muscularity among men 总被引:2,自引:2,他引:0
This study explored whether three dimensions of men's body dissatisfaction (muscularity, body fat, and height) are distinct from drive for muscularity (body image, behaviors, and attitudes) in a sample of 368 college men. If body dissatisfaction is a unique construct, then it will be associated with psychological well-being above and beyond the variance accounted for by drive for muscularity body image, behaviors, and attitudes. Findings revealed such incremental evidence, supporting body dissatisfaction's unique contribution to all five investigated indices of psychological well-being. Overall, body dissatisfaction and drive for muscularity are not completely parallel constructs, highlighting the need to assess men's dissatisfaction with their muscularity, body fat, and height for a more comprehensive picture of their body image. 相似文献

The relationship between career adaptability, person and situation variables, and career concerns in young adults 总被引:1,自引:0,他引:1
We surveyed 245 first-year university students using measures of career concerns, career adaptability (career planning, career exploration, self-exploration, decision-making, self-regulation), goal-orientation (learning, performance-prove, performance-avoid) and social support (family, friends, significant others), and tested: (a) whether the career adaptability variables could be represented by a second-order factor of career adaptability; (b) whether career adaptability, goal-orientation and social support were associated with fewer career concerns; and (c) whether career adaptability mediated the relationship between goal-orientation and social support and career concerns. The study demonstrated that the career adaptability variables were inter-related and could be represented by a higher-order factor. Decision-making and self-exploration were negatively associated with career concerns, and decision-making mediated the relationship between goal-orientation and career concerns. Having more of a learning orientation was associated with more decision-making and fewer career concerns, whereas holding a performance-prove orientation was associated with poorer decision-making and more career concerns. 相似文献

Although previous studies have found interteaching to be an effective alternative to traditional methods of instruction, few studies have examined which of its components contribute to its effectiveness. In the current study, we examined whether manipulating quality points had an effect on our students' exam scores. In two sections of an undergraduate general psychology course, we used interteaching but alternated between quality points and no quality points several times throughout the semester; we also counterbalanced the order of presentation across sections. We found that quality points did not have an effect on exam scores. 相似文献

Research has shown that neighborhoods play a role in the etiology of violence. However, few adolescent relationship aggression (ARA) studies have objective measures of violent neighborhoods. Drawing on a nationally representative sample of youth, this study examines the association between ARA and local levels of violent crime (measured using geocoded Uniform Crime Report data from each of the youths’ residential neighborhoods). Study analyses are based on survey data from 723 youth (ages 10–18) in current or recent dating relationships (351 males and 372 females) in the Survey on Teen Relationships and Intimate Violence (STRiV), a national representative household panel survey exploring interpersonal violence and related aggression among adolescents. About 19% of the sample reported ARA victimization in their most recent dating relationship (ARA perpetration was 17%). Neighborhood violent crime in the study (males living in 86.9 and females 99.8) was slightly lower than the national average of 100. With a broad national sample, 40% non-Whites, hypotheses guided by theories of neighborhood influence were tested. The study did not find an association between neighborhood violent crime and ARA victimization and perpetration, controlling for key demographic factors. The results, for a broad range of high- and low-crime neighborhoods, suggest that neighborhood violence does not seem to affect individual rates of ARA. The results suggest the ARA victimization and perpetration are perhaps ubiquitous and found both in low and high violent crime neighborhoods, suggesting that addressing local violent crime rates alone does not seem to be a path to also reducing ARA. 相似文献

Two studies tested whether attributions of hostile intent (AHI) and anger for ambiguous child behaviors uniquely predict parents’ harsh verbal discipline (HVD) and harsh physical discipline (HPD) or whether AHI only predicts harsh discipline when AHI occurs in conjunction with anger, as suggested by the Integrated Cognitive Model of general aggression (Wilkowski & Robinson, 2010, J. Pers., 78, 9–38). Replicating previous studies, the expected positive bivariate relationships between AHI, anger, HVD, and HPD were found in Study 1 (N = 493). However, when AHI, anger, and the AHI by anger interaction were considered simultaneously, patterns of prediction varied by discipline type. For HVD, high levels of AHI, high levels of anger, and the AHI by anger interaction (at high levels of AHI and anger) each were significant predictors. For HPD, low levels of AHI, high levels of anger, and the AHI by anger interaction (at high levels of AHI and anger) were significant predictors, suggesting a possible suppressor effect for AHI. These results were replicated in Study 2 ( N = 503). Thus, there was support for the contention that AHI only predicts harsh discipline when AHI occurs in conjunction with anger with respect to HPD but this was not the case for HVD. Since AHI suppressor effects were observed for HPD in two large sample studies, variables that may account for the AHI suppressor effects and the need for testing more complex interactive predictive models of harsh parenting behaviors are discussed. 相似文献

Encountering the body of a child who died by suicide at the site of death is believed to be especially harmful for bereaved parents. We investigated the association between encountering the body at the site of the suicide and psychological distress in 666 suicide‐bereaved parents. Parents who had encountered their child's body at the site of the suicide (n = 147) did not have a higher risk of nightmares (relative risk [RR] 0.95, 95% confidence interval [CI] 0.67–1.35), intrusive memories (RR 0.97, 95% CI 0.84–1.13), avoidance of thoughts (RR 0.97, 95% CI 0.74–1.27), avoidance of places or things (RR 0.91, 95% CI 0.66–1.25), anxiety (RR 0.93, 95% CI 0.64–1.33), or depression (RR 0.94, 95% CI 0.63–1.42) compared with parents who had not encountered the body (n = 512). Our results suggest that losing a child by suicide is sufficiently disastrous by itself to elicit posttraumatic responses or psychiatric morbidity whether or not the parent has encountered the deceased child at the site of death. 相似文献
