This study describes the extent of caregiver instability (defined as a new placement for 1 week or longer in a different household and/or with a new caregiver) in a nationally representative sample of infants, followed for 5–7 years. Data were drawn from the National Survey of Child and Adolescent Well-Being (NSCAW), a longitudinal study of 5,501 children investigated for child maltreatment. The analysis sample was restricted to 1,196 infants. Overall, 85.6% of children who were infants at the time of the index maltreatment experienced at least one caregiver instability event during their first 2 years of life. Caregiver instability was associated with the child having a chronic health condition and the caregiver being older than 40 years of age at baseline. The levels of instability reported in this study from infancy to school entry are extremely high. Children with more risk factors were significantly more likely to experience caregiver instability than children with fewer risk factors. The repeated loss of a young child's primary caregiver or unavailable, neglectful care can be experienced as traumatic. Some evidence-based programs that are designed to work with young maltreated children can make a substantial positive difference in the lives of vulnerable infants. 相似文献

The goal of this study was to determine the stability of Total Prostrate Specific antigen (PSA-T) and Free Prostrate Specific
Antigen (PSA-F) in archival serum stored at 4°C and −20°C and subjected to temperature shift due to interruption in power
supply. Our study showed that PSA-T was stable up to 285 days and PSA-F was stable for 158 days under these conditions. Since
power supply interruption is an unavoidable problem in developing nations, our study has implication on the validity of measurement
of PSA-T and PSA-F in serum that was not properly stored due to emergency situations and for certain types of retrospective
studies. 相似文献
