This research examines the impact of teenage childbearing on secondary school completion, while focusing on the problem of causal ambiguity in the relationships among self-determined behaviours. Techniques for dealing with the teenage childbearing problem are discussed, and results from these methods are compared. Data from the High School and Beyond Study on young women (n = 5257) who were enrolled as sophomores in sample schools in February 1980 and who had not given birth before November 1980 are used. Results indicate that teen childbearing reduces the probability of completing high school by 8% to 10%. Some evidence suggests that programs that target reduction of teen childbearing in improving young women's education and subsequent economic and labor force outcomes.  相似文献

This study examined the relationship among the recovery grip strength, functional outcomes, and work performance following occupational therapy intervention for hand trauma. This study had a sample size of 15 participants whose recovery grip strength was measured using a Jamar dynamometer, whose satisfaction with outcomes was measured by the Michigan Hand Outcomes Questionnaire (MHQ), and whose compliance with the home therapy program was measured by a visual analog scale (VAS). A Pearson r correlation demonstrated a significant relationship between recovery grip strength and two MHQ subset scores: overall hand function (r = 0.59, p = 0.019) and activities of daily living (ADL) performance (r = 0.61, p = 0.016). The participants' self-rating of compliance did not predict or influence either recovery grip strength or MHQ scores. A moderate positive correlation approaching significance (r = 0.51, p = 0.052) was found between grip strength and overall MHQ scores. The researchers concluded that a recovery grip strength measure should be used along with functional measures to appropriately assess overall hand function following hand trauma.  相似文献

Little is known about the social support networks of maltreated youth or how youth in foster care may compare with those who remain with their parent(s). Social network characteristics and perceived social support were examined between (1) maltreated and comparison youth, (2) maltreated youth who remained with their biological parent, those with a foster parent, or a those with a kin caregiver, and (3) youth in stable placements and those who have changed placements. Data came from a sample of 454 adolescents (241 boys, 9–13 years old at enrollment) who took part in a longitudinal study of child maltreatment. Participants completed three assessments approximately 1 year apart. Results showed that on average, maltreated adolescents named significantly fewer people in their network than comparison adolescents. At Time 2, comparison adolescents reported more same‐aged friends. In the maltreatment group, youth with a foster parent reported significantly more older friends than maltreated youth with a kin caregiver. Fewer maltreated youth named a biological parent on the social support questionnaire at all three time points. More youth in kinship care described their caregiver as supportive than those in foster care. These findings indicate that despite heterogeneous placement histories, social support networks among maltreated youth were very similar.  相似文献
