Low birth weight is a more common occurrence among Puerto Rican children than among children from most other racial and ethnic groups in the United States, and they are more likely to experience the added risk of living in poverty. This study addresses what is protective for the development 602 normal birth weight and 554 low birth weight children from the Puerto Rican Maternal and Infant Health Study. The results presented in the current analysis identify several protective influences for development (particularly maternal social support, medical insurance, and paternal employment) among low birth weight children (who are at a high risk for developmental problems), and almost none for normal birth weight children. The results largely support the contention that protective factors emerge, or increase in strength, only in the presence of risk, indicating the use of targeted child health programs based on birth weight are an effective and efficient way to improve the developmental well-being of young Puerto Rican children in the United States. 相似文献

Though often conflated, informal physical exercise and organized athletic participation have very different implications for adolescent sexual risk outcomes. The purpose of this research is to disaggregate strenuous exercise from sports, examine how each is associated with sexual risk, and explain the observed differences using the conceptual lens of cultural resource theory. Using a nationally representative sample of over 16,000 public and private high school students, we employ logistic regression to test hypotheses about the gender-specific and race-specific effects of strenuous exercise and athletic participation on adolescent sexual risk behavior. The results show that both forms of physical activity buffer sexual risk for girls. Strenuous exercise is associated with increased odds of sexual risk for boys. Sports and race interact to influence boys' sexual risk outcomes: Athletic participation is associated with lowered odds of sexual risk for white male adolescents, but heightened odds of sexual risk for black male adolescents. 相似文献

Studies of adolescent pregnancy risk are relevant to understanding responsible adolescent sexual behavior because most investigators have focused on the key proximal determinants of pregnancy--sexual intercourse and contraceptive use--rather than analyzing pregnancy status per se. Lesser pregnancy risk is associated with teens remaining sexually abstinent, postponing onset of intercourse, and having intercourse less often or with fewer partners, as well as by using contraception at first or most recent intercourse and by using contraception consistently over time. Living with a single parent, in a lower SES family, having older sexually active siblings or pregnant/parenting teenage sisters, being a victim of sexual abuse, and residing in disorganized/dangerous neighborhoods all place teens at elevated risk of adolescent pregnancy. Parent-child closeness or connectedness, and parental supervision or regulation of children, in combination with parents values against teen intercourse (or unprotected intercourse), decrease the risk of adolescent pregnancy. Studies about parent-child sexual communication and adolescent pregnancy risk are less conclusive, largely because of methodological complexities. 相似文献

Effective targeted and community HIV/STD prevention programs 总被引:1,自引:0,他引:1
Community interventions and interventions targeting specific groups at risk of STDs/HIV have demonstrated significant impacts on sexual behavior, particularly condom use and safer sex. The scientific evidence suggests the factors that make these interventions particularly effective include the establishment of community, including business and CBO partnerships; maintainance of the intervention post-research funding; and buy-in by the community or target group. The modification of risky normative beliefs through the use of opinion leaders and role models, and through intervention delivery by peer educators, is an important facet of such interventions. Interventions delivered by health professionals, absent a community base, appear to be unsuccessful. Where cultures or subcultures are targeted, the close involvement of such groups in the design and delivery of messages is critical to their success. Diffusion of interventions through existing social networks further extends the intervention into the community and acts to reinforce and maintain changes in peer norms toward safer sexual behavior. The available data confirm that community or medical infrastructure-based interventions are effective in changing sexual behavior and can reach a wider range of the population than face-to-face programs if they incorporate peer educators as role models in modifying norms, and if diffusion of the intervention is integral to the design. 相似文献

Forgiveness is a significant intervention for healing interpersonal injury. Yet therapists do not often use forgiveness intervention. Employing a semantic perspective and a survey design (n = 307), this study investigated whether the language used to rationalize forgiveness intervention (set at five levels: personal growth, relationship reconciliation, spiritual issue, others' growth, and pardoning/condoning) may affect its acceptability. Gender, problem type, and choice were also included in the analyses. Overall, forgiveness was found to be an acceptable intervention. A pardoning/condoning rationale led to significantly lower acceptability ratings. Other results are discussed. We conclude that therapists should be less apprehensive about using forgiveness, but need to inform themselves better concerning its purpose, process, and articulation. 相似文献

The theory,structure, and techniques for the inclusion of children in family therapy: a literature review 总被引:1,自引:0,他引:1
Many barriers prevent therapists from including young children in family therapy, despite the theoretical belief that every family member should be present. Although there is a wealth of literature describing how to include children, the information has not been compiled in a way that is easily accessible to therapists. In this article, we report the findings of an exhaustive and systematic literature review of 64 publications, published between 1972 and 1999, related to including children in family therapy. The purpose of this article is to offer therapists a succinct compilation of theoretical, structural, and practical aspects as well as a comprehensive listing of specific techniques for including children in family therapy. 相似文献

This article reviews some of the history of the cultural forces that shaped the diagnosis of multiple personality disorder/dissociative identity disorder and the subsequent abuses that occurred at the time of its popularization. Some of the implications that can be drawn from these kinds of historical excesses in the field of mental health will be discussed. The article concludes by underscoring the ethical obligation inherent in maintaining healthy professional skepticism toward ideas driven by ideology and fad, rather than scientific empiricism. 相似文献

Researchers have noted that with the onset of adolescence, girls' voices become muted and school achievement drops. Girls learn that the expression of strong feelings leads to distance from others, and that full use of their bodies and minds cause others discomfort. Self-esteem suffers and girls become at risk for destructive behaviors. Most studies have been done with middle class Caucasian girls. Those few studies done with young girls of color speak of girls on the margin who seem to resist losing their voices and their self-esteem. This article describes a study involving 5th–8th grade girls participating in an Advisory group program at a grammar school in a predominantly Mexican community of a large city. Group sessions were taped and analyzed for common themes including voice and self-esteem. Focus was directed to the influence of the bicultural/bilingual environment in analysis of group content. Implications for practice are included. 相似文献

Evolutionary psychologists such as Wilson and Daly (1993b) hypothesize that one goal of male-perpetrated domestic violence is control over female sexuality, including the deterrence of infidelity. According to this hypothesis, domestic violence varies with women's reproductive value or expected future reproduction, declining steeply as women age. We tested this hypothesis with a sample of 3,969 cases of male-perpetrated partner-abuse reported to a single police precinct in a large urban area over a 14-year period. Results show that (a) rates of domestic violence decrease as women age, (b) younger men are at greatest risk for perpetrating domestic violence, (c) younger, reproductive age women incur nearly 10 times the risk of domestic violence as do older, post-reproductive age women, and (d) the greater risk of domestic violence incurred by reproductive age women is not attributable solely to mateship to younger, more violent men. Discussion addresses theoretical implications of these findings and suggests a refinement of the feminist hypothesis of domestic violence against women. 相似文献
