ABSTRACTObjective: To examine the association between degree of real-life closeness of social media (SM) contacts and depressive symptoms. Participants: Students ages 18–30 (N = 1124) were recruited in August 2016. Methods: Participants completed an online survey assessing SM use and depression. We used multivariable logistic regression to assess associations between real-life closeness of SM contacts and depressive symptoms. Results: After controlling for covariates, each 10% increase in the proportion of SM friends with whom participants had no face-to-face relationship was associated with a 9% increase in odds of depressive symptoms (AOR = 1.09; 95% CI = 1.05–1.13). However, each 10% increase in the proportion of SM friends with whom participants had a close face-to-face relationship was associated with a 7% decrease in depressive symptoms (AOR = 0.93; 95% CI = 0.89–0.97). Conclusions: Having no in-person relationship with SM contacts is associated with increased depressive symptoms; however, having close in-person relationships with SM contacts is associated with decreased depressive symptoms. 相似文献

The aim of this study was to examine the psychometric properties and preliminary validity of a newly developed 16-item measure to assess maladaptive responses to the stress of being at risk for HIV infection among HIV-negative gay men. The measure consisted of three factors: (a) fatalistic beliefs about maintaining an HIV-negative serostatus, (b) reduced perceived severity of HIV infection due to advances in medical treatment of HIV and AIDS, and (c) negative affective states associated with the risk of HIV infection. A total of 285 HIV-negative gay men at a counseling program in New York City participated in the study. Confirmatory factor analyses supported the three-factor model as an acceptable model fit: non-normed fit index = .91, comparative fit index = .92, goodness-of-fit index = .90, and root mean square error of approximation = .07. The measure and its subscales obtained in this sample achieved adequate internal consistency coefficients. Construct validity was supported by significant and positive associations with internalized homophobia, depression, self-justifications for the last unprotected anal intercourse (UAI), and actual UAI with casual sex partners. Understanding the dynamics of maladaptive responses to the epidemic and intense anxieties elicited by HIV risk among HIV-negative gay men living in a place of high seroprevalence provides useful information to guide psychosocial interventions in the population. 相似文献

Emerging research demonstrates that mindfulness is effective in reducing health care worker burnout. The aim of this quantitative pilot study was to examine the effectiveness of a mindfulness intervention on social work students. The investigation utilized a pretest/posttest design. Findings from the study demonstrated an increase in knowledge (p < .001), self-efficacy (p < .001), and beliefs (p < .005) related to mindfulness following a group-based mindfulness intervention. Reflections on the first author’s need to resist her group work instincts to test the effectiveness of the mindfulness intervention are shared. 相似文献

ABSTRACTThe Society for Adolescent Health and Medicine emphasizes the need for research to focus on the health outcomes of sexual minority youth (i.e., lesbian, gay, bisexual, transgender, queer). However, sexual minority youth (SMY) are often less willing to participate in research studies where parental consent is required due to potential victimization and discrimination. This is a major concern given that more research is needed to understand the health needs of this population, especially in terms of suicide, substance use, and HIV prevention. The National Suicide Prevention Strategy classifies SMY as a high-risk group, emphasizing the need to explore suicide risks (along with other health outcomes) among this group. However, this high-risk classification also increases the safeguards necessary to conduct research with this population. Many researchers have argued for waivers of parental consent, but such waivers present with several ethical implications. This article discusses ethical principles, risks, benefits, safeguards, and potential alternative approaches to waivers of parental consent for SMY. We conclude by emphasizing the need for policy changes to allow parental consent waivers for research targeting SMY. 相似文献

Good things come in threes: Single-parent multigenerational family structure and adolescent adjustment 总被引:1,自引:0,他引:1
Using data from the National Educational Longitudinal Study (NELS), we found that teenagers who live in nonmarried families are less likely to graduate from high school or to attend college, more likely to smoke or drink, and more likely to initiate sexual activity. Not all nonmarried families are alike, however. In particular, teenagers living with their single mothers and with at least one grandparent in multigenerational households have developmental outcomes that are at least as good and often better than the outcomes of teenagers in married families. These findings obtain when a wide array of economic resources, parenting behavior, and home and school characteristics are controlled for. 相似文献

This paper introduces a stochastic algorithm for computing symmetric Markov perfect equilibria. The algorithm computes equilibrium policy and value functions, and generates a transition kernel for the (stochastic) evolution of the state of the system. It has two features that together imply that it need not be subject to the curse of dimensionality. First, the integral that determines continuation values is never calculated; rather it is approximated by a simple average of returns from past outcomes of the algorithm, an approximation whose computational burden is not tied to the dimension of the state space. Second, iterations of the algorithm update value and policy functions at a single (rather than at all possible) points in the state space. Random draws from a distribution set by the updated policies determine the location of the next iteration's updates. This selection only repeatedly hits the recurrent class of points, a subset whose cardinality is not directly tied to that of the state space. Numerical results for industrial organization problems show that our algorithm can increase speed and decrease memory requirements by several orders of magnitude. 相似文献

SUMMARY At a fiftieth birthday party 17 years ago, a group of women—lesbian, bisexual, and straight—decided to create a conscious community in which they could age together. The group, where they discuss this process and support each other, is politically and personally meaningful, and a buffer against the isolation and powerlessness many aging women experience. They meet monthly, and at weekend retreats twice a year. They have become a “family of choice,” sharing holidays and celebrations and supporting each other when necessary and possible. After several years, they decided to commit for life. In the group, each feels held and seen in the complex experience of aging in today's world. 相似文献
