DEPRESSIVE SYMPTOMS AND MOTHER/INFANT INTERACTION

该补助金的目的是继续我们的纵向研究， 婴儿和母亲的高，中等或极低 抑郁水平对母婴结局的影响; B）纵向 观察自然发生的母婴互动 行为是在家庭环境中进行的， c）关于母亲和父亲抑郁症状的数据， 精神共病和情感状态，收集在每个 d）一组单独的母亲， 抑郁症状的识别和跟踪。 要评估的主要假设是：a）行为 和情感风格的母亲，无论是高或极低 抑郁症状的水平将不同于那些母亲， 中度症状; B）婴儿行为模式和情感意愿 与母体症状水平有关;以及c）严重程度和 产妇症状的慢性化将对 母婴互动和婴儿结局。 我们的假设是 在相互调节模型的指导下，该模型假定婴儿 发展取决于婴儿的持续能力- 照顾者对调节幼儿的情感状态， 婴儿掌握主要发展任务的能力 婴儿期。 母亲和婴儿的自然行为是 在家中拍摄，当婴儿是3，6和12个月大时。 此外，婴儿和母亲在实验室进行录像， 12个月的安斯沃思的奇怪的情况和婴儿陌生人 玩吧 同时获得母亲的诊断史。 在每个年龄段， 母亲和父亲完成问卷， 抑郁症状、其他精神症状和情感障碍 status. 婴儿和母亲的行为和影响是从评分 录像带由蒙面的，可靠的编码器使用详细的编码系统。 将使用多变量技术来评估假设。 这一项目的初步工作和进展很大， 初步结果支持了这一假设。 这项研究将显著 增加我们对母亲抑郁症的影响的理解 母婴互动的行为学及相关因素 和婴儿第一年的社会情感发展。

The objective of this grant is to continue our longitudinal study of infants and mothers with either high, mid-range, or extremely low levels of depression on maternal and infant outcomes; b) longitudinal observations of naturally occurring maternal and infant interactive behavior are made in the home setting during the first year post partum; c) data on maternal and paternal depressive symptoms, psychiatric co-morbidities, and affective status are collected at each visit; and d) a separate group of mothers with extremely low levels of depressive symptoms is identified and followed. The primary hypotheses to be evaluated are that a) the behavioral and affective styles of mothers with either high or extremely low levels of depressive symptoms will differ from those of mothers with mid-range symptoms; b) patterns of infant behavior and affect will be related to maternal symptom levels; and c) the severity and chronicity of maternal symptoms will have negative effects on mother-infant interaction and infant outcomes. Our hypotheses are guided by the Mutual Regulation Model, which posits that infant development is dependent on the ongoing ability of the infant- caregiver dyad to regulate the infant~s affective states and to foster the infant~s ability to master the major developmental tasks of infancy. The naturally occurring behavior of mothers and infants is videotaped at home when infants are 3,6, and 12 months old. Additionally, infants and mothers are videotaped in the laboratory at 12 months during Ainsworth~s Strange Situation and infant-stranger play. Mothers~ diagnostic history is also obtained. At each age, mothers and fathers complete questionnaires regarding their current depressive symptoms, other psychiatric symptoms, and affective status. Infant and maternal behavior and affect are scored from the videotapes by masked, reliable coders using detailed coding systems. Multivariate techniques will be used to evaluate the hypotheses. Preliminary work and progress on this project has been substantial, and initial results support the hypotheses. This study will markedly increase our understanding of the effects of maternal depressive symptomatology and associated factors on mother-infant interaction and infant socio-emotional development during the first year.
