Postpartum Psychopathology and Teenage Mothers

描述（由申请人提供）：该项目的长期目标是有助于了解产后精神病理学的性质和起源，以及青少年母亲养育子女的困难，以及提高母亲和儿童未来心理健康风险的交易关系。具体目标是调查心理健康问题作为少女怀孕的前兆，产后精神病理学的风险和青少年养育，母亲的精神病理学和婴儿失调的行为和情绪之间的相互作用过程。为了发展作为一个独立的调查所需的具体专业知识，这K 01建议包括三个培训目标的候选人：（一）获得特定的青少年心理病理学发展模式的更全面的了解;（二）发展技能，在青少年养育和婴儿失调的评估;和（三）发展纵向统计分析的专业知识，随着时间的推移研究发展现象。 这些目标将在一项关于女孩行为和情感发展的纵向、大规模（n= 2 451）调查的前瞻性子研究（匹兹堡女孩研究：PGS）中实现。在子研究数据收集开始时，PGS中的女孩年龄为11-14岁，并且已经使用多名受试者收集了6次年度数据。据估计，239名青少年将在K 01奖励期间成为母亲，至少有191名青少年将参加子研究。参与者将被要求在分娩后2-3个月和12个月时与婴儿一起访问研究实验室，以评估母亲的心理健康，养育和婴儿行为，并拍摄母婴互动。该项目提供的信息最终可能会改善儿童的福利，导致制定早期干预措施，以减少少女怀孕、产后精神病理学和青少年养育子女困难等对后代产生长期不利影响的心理健康风险。

DESCRIPTION (provided by applicant): The long-term objectives of this project are to contribute to knowledge about the nature and origins of postpartum psychopathology and parenting difficulties among teenage mothers, and the transactional relationships that heighten future mental health risks for both mother and child. The specific aims are to investigate mental health problems as precursors to teenage pregnancy, risks for postpartum psychopathology and the reciprocal processes between teenage parenting, maternal psychopathology and infant dysregulated behavior and emotions. In order to develop specific expertise required as an independent investigator, this K01 proposal encompasses three training goals for the candidate: (i) to gain a fuller understanding of developmental models of psychopathology specific to teenagers; (ii) to develop skills in the assessment of teenage parenting and infant dysregulation; and (iii) to develop expertise in longitudinal statistical analyses to study developmental phenomena over time. These goals will be achieved in a prospective substudy of a longitudinal, large-scale (n=2,451) investigation of girls' behavioral and emotional development (the Pittsburgh Girls Study: PGS). At the start of the substudy data collection, the girls in the PGS will be ages 11-14 years and 6 annual waves of data will already have been collected using multiple informants. It is estimated that 239 teenagers will become mothers during the K01 award period and that a minimum of 191 will participate in the substudy. Participants will be asked to visit the research laboratory with their infant at 2-3 months and at 12 months post delivery for assessment of maternal mental health, parenting and infant behavior and filming of mother-infant interactions. Information from this project may ultimately improve children's welfare by leading to the development of early interventions to reduce mental health risks for teenage pregnancy, postpartum psychopathology and parenting difficulties among adolescents that have long-term, adverse consequences for offspring.
