Activism is responsible for many of the positive social changes we have seen across time, and is central to pushing for continued social change. However, these positive outcomes do not come without a cost, as activism can also be draining and can lead to physical and emotional harm for those involved. Social policies and intervention programs have addressed how to help people maintain their engagement with activism aims, though few have considered the motivational role of purpose in life. As purpose in life involves a sustained commitment to one's goals, having a purpose in life centered around activism may help an individual remain committed to activism and to the creation of change in the face of these obstacles. If activist purpose can help us understand and predict who is likely to remain engaged in activism, then it is valuable to consider what factors influence the development of activist purpose, in order to continue necessary social change. Thus, in this work we define activist purpose, and theorize as to what factors may be relevant to the development of an activist purpose by situating predictors of activism and collective action within the literature on pathways to purpose in life. This work may thus provide a greater understanding of how to encourage activism or reduce the harmful effects associated with activism.  相似文献

This study expands on previous research on adolescent problem behaviors by examining whether different constellations of problem behavior in adolescence differentially impact outcomes during emerging adulthood. Data from the in-home interviews of waves 2 and 3 of the National Longitudinal Study of Adolescent Health (Add Health) were used to examine these relationships. Latent class analysis, using nineteen problem behaviors measured at wave 2, identified three classes of adolescents representing “low risk, abstainers,” “sexually-active, experimenters,” and a “high risk, diverse behavior” group. Multivariate logistic regression analyses were then used to identify class differences (measured at wave 3) in social stability, general health and service utilization, and criminal justice system involvement during emerging adulthood. Important class differences in the likelihood of negative outcomes during early adulthood were identified. The implications of these findings and suggestions for future research are discussed.  相似文献

The rapid clinical implementation of cell-free DNA (cfDNA) screening, a non-invasive method of prenatal genetic screening, has outpaced research on its social and ethical implications. This study is the first to compare the ethical and practical views of Spanish- and English-speaking pregnant women in the United States about cfDNA screening. Semi-structured interviews were conducted with diverse Spanish- and English-speaking women who had received prenatal care at a large academic medical center. Of the 24 interviewees, ten were Latinas who were interviewed in Spanish; English-language interviews were conducted with seven non-Hispanic Asian and seven non-Hispanic White women. Participants held positive opinions concerning the accuracy of cfDNA screening and often noted that it would enhance preparedness. Participants also expressed concerns about the possibility of inaccurate results and the potentially negative effects of cfDNA screening on the experience of pregnancy. Differences emerged between Spanish and English speakers in their portrayals of their relationships with prenatal health care providers, the extent to which they questioned providers’ advice, their ethical concerns, and their informational needs. We emphasize the importance of customizing prenatal test counseling to the needs of the individual patient, providing educationally appropriate counseling and literature, and mitigating potential language barriers.  相似文献

Participants typically process same-race faces more quickly and more accurately than cross-race faces. This deficit is amplified in the right hemisphere of the brain, presumably due to its involvement in configural processing. The present research tested the idea that cross-race contact tunes cognitive and perceptual systems, influencing this asymmetric race-based deficit in face processing. Participants with high and low levels of contact performed a lateralized recognition task with same- and cross-race faces. Replicating prior work, participants with minimal contact showed cross-race deficits in processing that were larger in the right hemisphere. For participants with more contact, this lateralized deficit disappeared. This effect of contact seems to be independent of race-based attitudes (e.g., prejudice).  相似文献

Little is known about the specific patterns of adjustment among newly diagnosed acute leukemia patients and their caregivers. This study examined the trajectories of patient and caregiver distress over time as well as the extent to which marital satisfaction and social support moderated these trajectories among those with significant-other caregivers. Forty six patient-caregiver dyads provided ratings at four time points: within 1 week of diagnosis (T1), 2 week follow-up (T2), 6 week follow-up (T3) and 12 week follow-up (T4). As anticipated, patients and caregivers reported higher levels of distress around the time of diagnosis than they did during subsequent time points. Marital satisfaction was a significant predictor of distress among patients, whereas among caregivers, social support predicted distress and quality of life. Results support the inclusion of relational variables such as social support and relationship satisfaction in the assessment of newly diagnosed patients and families in order to best identify those at risk for distress over time.  相似文献
