Efforts to link media use to adolescents' sexual initiation have produced somewhat inconsistent results, perhaps as a result of the limited framing of the question. This study sought to expand current approaches by sampling college students instead of high school students, by investigating a range of sexual behaviors and media formats, and by testing a model that featured sexual cognitions as mediators. We tested our model with a sample of 796 heterosexual, male college students who reported on their regular consumption of 4 media (prime-time TV programs, music videos, movies, and men's magazines); their attitudes toward abstinence, the male sexual role, and nonrelational sex; their perceptions of peer sexual behavior; and several aspects of their sexual behavior (e.g., number of sexual partners). Findings revealed strong support for our mediated model, with exposure to men's magazines and movies contributing most strongly to their sexual cognitions, and with men's cognitions, in turn, contributing heavily to their sexual behavior. Some direct connections from media use to sexual behavior also emerged. Together, the findings provide insight into both potential mechanisms for and new approaches to addressing this issue.  相似文献

Across two studies, we test for sex differences in the factor structure, factor loadings, concurrent validity, and means of the Three Domain Disgust Scale. In Study 1, we find that the Three Domain Disgust Scale has indistinguishable factor structure and factor loadings for men and women. In Study 2, we find a small sex difference in sensitivity to pathogen and moral disgust and a large sex difference in sensitivity to sexual disgust, with women more sensitive to disgust across domains. However, correlations between Three Domain Disgust Scale factors and the five factors and 30 facets of the NEO Personality Inventory were indistinguishable between the sexes. These findings suggest that, despite mean sex differences in disgust sensitivity, the Three Domain Disgust Scale measures similar constructs in men and women. Implications for understanding the constructs measured by the Three Domain Disgust Scale are discussed.  相似文献

The early relationship between a mother and her very low birth weight (VLBW; <1.5 kg) infant may be difficult to evaluate. Therefore, we aimed to develop a useful and practical method to describe a mother's early relationship with her VLBW infant. Mothers (mean age=27 years, 46% married) of 119 singleton VLBW infants (mean BW=1,056 g, mean GA=28 weeks) admitted to the neonatal ICU at Rainbow Babies and Children's Hospital completed a novel questionnaire regarding their feelings about their infant at 3 weeks' postnatal age, and at 35 weeks', 40 weeks' (term), and 4 months' postmenstrual ages. Factor analysis of initial interview data was used to construct subscales to measure unique domains hypothesized to underpin the beginning maternal–infant relationship. Three subscales were identified: (a) The Worry subscale focuses on the mother's concerns about her infant's current medical condition and future development, (b) the Enjoyment subscale examines the mother's positive feelings about and responsiveness to her infant, and (c) the Separation Anxiety subscale examines the mother's mental anxiety about being physically separated from her infant. Statistical and clinical validation of the subscales produced positive supporting evidence that the subscales are a meaningful measure of the mother–infant relationship. We have developed a unique and practical measure for describing the early mother–VLBW infant relationship.  相似文献

Most couples therapy theories are developed and tested in the USA. In this clinical study, we investigated such therapies in a Swedish context. Over 300 couples were enrolled in the study of whom just under half completed the end‐of‐treatment assessment and just over 40 per cent a two‐year follow‐up. At the start, the study group displayed severe problems in marital adjustment, dyadic interactions and psychiatric symptoms. A relatively short treatment was used and 50 per cent of the couples attended less than nine sessions. Outcomes of treatment showed significant improvements in relationship matters, individual mental health and enhanced coping abilities. At long‐term follow‐up, all results remained the same and in some aspects improved for both sexes. This study confirms the effectiveness of such therapies in a Swedish context.  相似文献

Parent influences on early childhood internalizing difficulties   总被引:1,自引:0,他引:1  
Children's internalizing problems are a concerning mental health issue, due to significant prevalence and continuity over time. This study tested a multivariate model predicting young children's internalizing behaviors from parenting practices, parents' anxiety–depression and family stressors. A community sample of 2 year old children (N = 112) was followed longitudinally to 4 years. Parents completed questionnaires and playroom observations provided independent measures of parenting and child variables. Predictors of early childhood internalizing difficulties were over-involved/protective parenting, low warm-engaged parenting, and parental anxiety–depression. Family life-stress and parental anxiety–depression also predicted problematic parenting practices. These findings were discussed within the context of the design of early childhood parenting programs to prevent anxiety and depression in children.  相似文献

We examined the predictors for successful discharge from out-of-home care of children with complex needs placed in a novel comprehensive service intervention (Manatee Model) and compared their discharge experiences to their out-of-home counterparts from the same county. The study design consisted of a longitudinal two-year comparison of these two groups. A total of 147 cases were included in the analysis, and the propensity scoring technique was used to equate the groups. Among children admitted to the Manatee Model, boys, White children, younger children, those who came from a single-parent family, those who were abused, and those who had a disability (physical or emotional disability or medical condition) were found less likely to successfully exit within the two years when these predictors were examined separately. Multivariate analyses indicated that only age at the time of removal and health status were significantly associated with successful discharge. Implications of the findings are discussed.  相似文献
