Much of society deems pre-marital adolescent sexual activity to be deviant. Current research seeks to determine if losing one’s virginity has an impact on participation in delinquent acts. It is hypothesized that youth who are more socially bonded to conventional people and activities, with higher levels of self-control, will not have participated in sexual intercourse and will have lower rates of delinquency. Data from Add Health are analyzed. Results do not indicate a significant effect of virginal status on delinquency. However, various social bonds were found to differentially effect delinquency for virgins and non-virgins, which may be important to consider.  相似文献

Elevated impulsivity is thought to facilitate the transition from suicidal thoughts to suicidal behavior. Therefore, impulsivity should distinguish those who have attempted suicide (attempters) from those who have only considered suicide (ideators-only). This hypothesis was examined in three large nonclinical samples: (1) 2,011 military recruits, (2) 1,296 college students, and (3) 399 high school students. In sample 1, contrary to traditional models of suicide risk, a unidimensional measure of impulsivity failed to distinguish attempters from ideators-only. In samples 2 and 3, which were administered a multidimensional measure of impulsivity (i.e., the UPPS impulsive behavior scale; Whiteside & Lynam, 2001), different impulsivity-related traits characterized attempters and ideators-only. Whereas both attempters and ideators-only exhibited high urgency (the tendency to act impulsive in the face of negative emotions), only attempters exhibited poor premeditation (a diminished ability to think through the consequences of one's actions). Neither attempters nor ideators-only exhibited high sensation seeking or lack of perseverance. Future research should continue to distinguish impulsivity-related traits that predict suicide ideation from those that predict suicide attempts, and models of suicide risk should be revised accordingly.  相似文献

Assessing children’s episodic future thinking by having them select items for future use may be assessing their functional reasoning about the future rather than their future episodic thinking. In an attempt to circumvent this problem, we capitalised on the fact that episodic cognition necessarily has a spatial format (Clayton and Russell, 2009, Hassabis and Maguire, 2007). Accordingly, we asked children of 3, 4, and 5 to chose items they would need to play a game (blow football) from the opposite side of the table on which they had never before played. The crucial item was the box that was needed by children to reach the table from the other side. Over four experiments, we demonstrated that, while children of 3 perform poorly on future questions and children of 5 generally perform quite well, children of 4 years find a question about what they themselves will need to play in the future harder to answer than a similar question posed about another child. We suggest that this result is due to the ‘growth error’ of over-applying newly-developed Level 2 perspective-taking skills (Flavell et al., 1981), which encourages the selection of non-functional items. The data are discussed in terms of perspective-taking abilities in children and of the neural correlates of episodic cognition, navigation, and theory of mind.  相似文献

Anger has been at the center of religiopolitical conflicts and has been associated with well‐being. This study examined the role of Muslim anger in sociopolitical events perceived as a sacred violation. A Muslim sample (N = 151) identified adverse political events that have deeply affected them; and completed measures of anger, sacred violations, perceptions of injustice, and religiousness. Sacred violations and perceptions of injustice were associated with greater levels of anger, with sacred violations being the stronger predictor. Post hoc analyses revealed that surrender problem‐solving style increased anger control. The findings provide broad support for the importance of religious appraisals of adverse political events in Muslim anger.  相似文献

Critical consciousness includes an understanding of structural oppression, agency to act and actions to redress oppression. Questions remain regarding how youth's experiences with oppression and their social identities might relate to their critical consciousness. In this study, we explored associations between critical consciousness (critical reflection, critical agency, and action) and sociocultural factors (racial identity, racial socialization, and racial stress) among Black adolescents (n = 604; Mage = 15.44, SD = 1.24). We used latent profile analysis and identified four profiles of critical consciousness: Precritical Bystander (62.7%), Liberated Actor (19.9%), Precritical Actor (10.8%), and Acritical Bystander (6.6%). These profiles were distinct in critical reflection, critical agency, and critical action. Next, we examined associations between critical consciousness profiles and sociocultural factors. We found that profile membership was differentially associated with some aspects of racial identity, racial socialization, and racial stress. These findings suggest that there are specific patterns of critical consciousness among Black youth which are differentially associated with racial identity, racial socialization that emphasizes cultural pride, and experiences of cultural racism.

Interventions to assist reproductive health decision-making in populations affected by sickle cell disease (SCD) or trait (SCT) lack proven efficacy over time. Our aim was to compare effects of CHOICES, a Web-based multimedia education program on implementing informed reproductive plans, and usual care education (e-Book) on reproductive knowledge, intention, and behavior over 24 months. We randomized 234 participants with SCD (n?=?138) or SCT (n?=?96) (age 18–35 years, 35 % male, 94 % African American) to CHOICES and e-Book groups. Participants completed a sickle cell-specific reproductive measure before and four times after the intervention (6, 12, 18 and 24 months). Compared to the e-Book group the CHOICES group had significantly more improvement in knowledge over time (p?=?.004) but not intention (p?=?.18) or behavior (p?=?.69). At baseline, 114 (48.7 %) participants reported having partners who would not put the couple at risk for their children inheriting SCD. Of the 116 (49.6 %) at-risk participants, a higher poroportion of those who were in the CHOICES group chose partners that reduced their risk by the last visit than the e-Book group (p?=?.04). Study findings provide important insights for designing a national trial of the CHOICES intervention focusing on subjects whose partner status puts them at risk for having a child with SCD.  相似文献
