Although prior work suggests that how adolescent girls feel about their body is associated with their sexual behavior, we have less insight into the reasons why. We conducted semi-structured interviews with 25 African American adolescent girls (11–14 years of age), 18 Latina adolescents (14–17 years of age), and their maternal caregivers to explore why this association may exist. Both adolescent girls and their maternal caregivers were asked “Who is more likely to have sex, a girl who likes the way her body looks or a girl who doesn’t like the way her body looks?” A similar question was asked about condom use. Interviews were digitally recorded, transcribed, and coded for emergent themes using thematic analysis. Participants’ responded that both girls with a positive body image and those with a negative body image may be likely to have sex because of self- and body-esteem. Two sub-themes emerged that further explained why low self- and body-esteem mattered for girls who have a negative perception of their body: (a) feeling appreciated (b) easily persuaded. Most participants noted that girls with a positive body image perception would be more likely to use condoms. Emergent themes for using condoms were: (a) pregnancy/STI protection; and (b) body preservation. Our findings have implications for empirically exploring the pathways through which body image perceptions relate to adolescent sexual behaviors, and the possibility that universal prevention programs may not resonate similarly for all adolescent girls.  相似文献

Anthropogenic noise pollution is recognized as a major global stressor of animals. While many studies have assessed the unimodal impacts of noise pollution with a focus on intraspecific acoustic communication, little is known about noise pollution on the perception of visual and chemical information. The ‘distracted prey hypothesis’ posits that processing noise interferes with processing other information in the brain. Here, we found evidence for such a cross-modal effect of noise on the antipredator behaviour of a freshwater prey fish, the fathead minnow, Pimephales promelas. In laboratory trials, exposure to noise from a motorboat caused the total absence of the classical fright reaction of minnows to conspecific alarm cues, whereas an ambient noise control had no such impact. In natural habitats, the impairment of such antipredator behaviour due to noise pollution could have major fitness consequences. We discuss how our findings translate to animal ecology and the need for future studies that target specific management decisions regarding noise pollution.  相似文献

We explored how two types of procrastination (indecision and behavioral), contribute to problems with clutter across three adult U.S. samples differing as generational cohorts. An online survey was administered to college students (mean age = 21) and younger adults recruited using Amazon’s Mechanical Turk (MTurk; mean age = 31), plus older adults recruited with help from the Institute for Challenging Disorganization (mean age = 54) (http://challengingdisorganization.org). Hierarchical linear regression revealed that behavioral procrastination contributed significantly to an increasingly larger percentage of explained variance in clutter problems across the generational cohorts in a series of separate analyses. The addition of indecision as a variable led to a significant incremental increase in explained variance for the younger and older adult samples, but not for the student sample. Clutter problems led to a significant decrease in satisfaction with life among older adults. Findings suggest that general procrastination tendencies may enable a lifelong pattern of responses to one’s environment that become increasingly maladaptive throughout the life cycle - simultaneously delaying disposal decisions.  相似文献

Procrastination is a self‐regulatory failure, whose costs are debated. Here, we establish its impact in the workplace. Using an Internet sample, we assessed 22,053 individuals in terms of their sex, employment status, employment duration, income, occupational attainment and level of procrastination. High levels of procrastination is associated with lower salaries, shorter durations of employment, and a greater likelihood of being unemployed or under employed rather than working full‐time. Also, procrastination partially mediates sex's relationship with these work variables. Women tend to procrastinate less than men, evidently giving women an employment advantage. If women procrastinated the same as men, there should be 1.5 million fewer women in full‐time employment in the US. alone. Determining the causes of procrastination in the workplace, we also examined it at an occupational level. The results strongly support the gravitational hypothesis: jobs that require higher levels of motivational skills are less likely to retain procrastinators. However, there was some support that jobs can foster procrastination. Procrastinators tend to have jobs that are lower in intrinsically rewarding qualities.  相似文献

Numerous empirical studies have investigated the relationships between cardiovascular diseases (CVD) and patients’ psychological well-being, with a focus almost exclusively on its dark side. Very little is known on the impact of illness severity on both negative and positive indicators of patients’ well-being, as well as on the psychosocial variables that may mediate this association. Aim of the study was to investigate the impact of illness severity on depression as well as on health satisfaction and life satisfaction of patients undergoing a cardiovascular rehabilitation. It also aimed at testing the mediation of illness perception and self-efficacy beliefs in managing cardiac risk factors. The study involved 172 patients (mean age?=?66.43?years; SD?=?9.99?years; 76.2% men). Illness severity was measured in terms of left ventricular ejection fraction at discharge from the cardiology department, whereas all psychological dimensions were assessed one week later. Results showed significant relationships among illness severity, depression and health satisfaction that were fully mediated by illness perception and self-efficacy beliefs, but not significant relation between disease severity and life satisfaction (χ 2(1)?=?2.30, p?=?n.s.). Overall, findings underline the importance of working on illness perception and self-efficacy beliefs to contrast depression and to improve health and life satisfaction in patients with CVD.  相似文献

College students (174 females, 91 males) completed measures of shame, guilt, expectations for future success, and styles of anger expression. Significant gender differences were found in proneness for both shame and guilt, with young women exhibiting a greater propensity for shame and guilt than young men. For both females and males, however, shame-proneness was positively related to expressions of inward anger. Among males and females, guilt-proness was negatively related to outward anger, but positively related to anger control. For females, guilt-proness was also negatively related to expectations for future success. Multiple regression analyses indicated that for male and female late adolescents, the best positive predictor of shame-proneness was inward anger. Gender differences emerged in predicting guilt-proneness; greater anger control, lower outward anger, and lower expectations for future success significantly predicted this variable among females.  相似文献
