This is a study of psychosocial outcomes of adolescents born to teenage mothers. Adolescents' problem behaviors, psychological well-being, social support, school variables, and sexual behaviors are compared across three groups—those born to mothers 17 or younger, mothers 18–19 years old, and mothers 20 or older. Analyses from two samples of African American adolescents from Maryland (n = 205) and Michigan (n = 570) are reported. The results from both samples indicate that mother's age at birth is unrelated to adolescents' psychosocial outcomes. These two studies add to the limited number of analyses that examine adolescent outcomes for children of teen mothers. The results suggest that efforts to understand social structural determinants of healthy and problematic adolescent development may be more informative than examining the effects of mother's age. They also suggest that teen pregnancy prevention programs may be more effective if they are part of a larger prevention strategy that incorporates social structural change efforts and not only a focus on individual level change.  相似文献

We investigated the psychological impact of an organized visit to Polish concentration camps on Jewish-American adolescents. Eighty-seven adolescents who participated in a B'nai B'rith memorial visit to concentration camps in Poland completed measures of general psychological adjustment and posttraumatic stress disorder (PTSD) at four time-points: pretest, posttest, 6-month follow-up and 12-month follow-up. Measures included the SCL-90-R, the Mississippi Scale for PTSD, and the Impact of Events Scale (IES) for PTSD. On the SCL-90-R, changes in somatization, interpersonal sensitivity, obsessive-compulsive tendencies, depression, anxiety, and phobic anxiety were observed over time, with peak symptom scores at posttest and 6-month follow-up. Scores on the Mississippi Scale for PTSD and the IES Intrusion subscale also increased at 6-months. Predictors of PTSD symptoms on the Mississippi Scale included previous psychiatric treatment and SCL-90-R symptoms of paranoia, depression, and psychosis. Elevated psychotic symptoms on the SCL-90-R predicted PTSD symptoms on the IES. Jewish adolescents with preexisting symptoms of generalized distress or psychoticism appeared at increased risk for PTSD symptoms following exposure to Holocaust stimuli. This study contributes a prospective, multi-measure assessment of trauma reactions in adolescents.  相似文献

Anxiety Symptomatology in Mexican-American Adolescents   总被引:3,自引:0,他引:3  
Mexican-American adults and adolescents in general have been reported to have high levels of anxiety symptomatology. In our study of a tri-ethnic sample of 2528 junior and senior high school students, the Youth Self Report (YSR) version of the Child Behavior Checklist (CBCL) and a sociodemographic questionnaire was used to assess the anxiety symptoms of Hispanic youth. We compared the ratings on anxiety symptoms, using Achenbach's anxiety subscale on the YSR, between two populations. The anxiety levels of youth in coastal southeast Texas (Galveston County) were compared to the anxiety levels of youth in the lower Rio Grande Valley. We found that Mexican-Americans of the Lower Rio Grande Valley scored higher on anxiety symptoms than the tri-ethnic population of Galveston County. Other factors associated with higher anxiety scores for Mexican-American youths included being born outside the US, linguistic fluency, father absent from the home, mother's education, and household size. Multiple regression analyses showed that socio-economic status (SES), family composition, and linguistic fluency had a greater relative impact on anxiety symptomatology than all other factors, both for the total sample as well as for the Mexican-American sample. These results parallel previous findings, with Mexican-American adults, which suggest either higher risk for anxiety symptomatology or a culturally related bias in the reporting of such symptoms.  相似文献

This 1‐year longitudinal study examined relations between social comparison orientation (SCO) and socioemotional adjustment and academic achievement. A sample of Grades 7 and 8 students (N = 336, initial M age = 14.08 years) in China participated in the study. Data were collected from self‐reports, peer assessments and school records. It was found that early SCO positively contributed to later academic achievement. Moreover, the relations between early SCO and later socioemotional adjustment were moderated by the initial status of adolescents. Specifically, SCO was positively associated with social competence and negatively associated with depression in initially competent and well‐adjusted adolescents, but the pattern of the associations was opposite in initially incompetent and poorly adjusted adolescents. The results indicate that whereas SCO may contribute directly to academic achievement, its contributions to socioemotional development might depend on adolescents' initial status in adjustment.  相似文献

The effect of student‐to‐school‐counselor ratios on academic outcomes has been widely studied, yet few researchers have taken a multilevel approach. Using the nationally representative High School Longitudinal Study: 2009 dataset, the authors found ratios were significantly associated with student grade point average (GPA) and graduation. Attending a Title I school also was associated with students’ GPA, advanced placement/international baccalaureate credits earned, and postsecondary course taking. The authors discuss implications for advocacy and practice, contextualizing their findings within an ecological framework.  相似文献

该研究以377名中学生为被试,探讨了中学生消费决策风格的特点及其与家庭理财教育方式的关系。结果表明:(1)中学生消费决策风格部分符合Shim(1996)提出的二阶模型(包括质量导向、非理性导向、享乐导向和价格导向等四个二阶因子);(2)中学生消费决策风格的年级差异不显著,性别差异显著,男生在品牌导向上高于女生,在流行导向和娱乐导向上低于女生;(3)中学生消费决策风格可划分为决策随意型、决策紊乱型、决策理智型和决策实惠型;(4)父母消极的理财教育方式会导致中学生形成非理性导向或享乐导向的消费决策风格,而积极的教育引导则能在一定程度上减弱中学生的非理性决策风格,促进其形成质量导向的决策风格。  相似文献

Although the link between cognition and affect in the advertising context has been demonstrated in several studies, no research to date has considered adolescents’ affective responses to movie posters and their attitudes to negative and positive images. A 2 (between subjects) × 4 (within subjects) mixed‐factorial experiment design comprising two groups of subjects (80 adolescents and 80 young adults) and four advertising stimuli (two highly positive images and two highly negative images) was used to test the differences in the subjects’ attitudes to advertising, positive and negative affect, and viewing intentions. Although the adolescents, compared to the young adults, did not appear to have significantly stronger attitudes to emotional advertisements (ads), they showed a similar level of intensity of affective response when exposed to negative and positive images.  相似文献
