This study examined positive affect (PA) trajectories over the first year of life among infants of mothers with a history of depression ( = 191) as well as predictors (i.e., maternal prenatal and postpartum depression symptoms, maternal parenting behaviors) of those trajectories. Infant PA was observed in play and feeding tasks during lab visits at 3, 6, and 12 months of age; parenting behaviors were observed at 3 months. Mothers completed questionnaires regarding their symptoms of depression throughout the prenatal period and during the first 3 months postpartum. Growth curve analyses indicated that infant PA increased across time, and this finding replicated across both the play and feeding tasks, though increases slowed over time. Neither maternal prenatal nor postpartum depression symptoms predicted infants' PA trajectories, but mothers' PA, positive parenting, and disengaged parenting were associated with infant PA during the play task. Our finding that infant PA increased over the first year postpartum suggests PA trajectories among infants of mothers with a history of depression may be indices of resilience, despite risks associated with their mothers' history of depression. Furthermore, this study highlights parenting behaviors that may be important targets of prevention and early intervention efforts to bolster infant PA.
本研究考察了有抑郁病史母亲的婴儿（n = 191）在生命第一年中的积极情绪（PA）轨迹，以及这些轨迹的预测因素（即母亲产前和产后的抑郁症状、母亲的养育行为）。在婴儿3个月、6个月和12个月大时进行实验室访视期间，观察他们在玩耍和进食任务中的积极情绪；在3个月时观察养育行为。母亲们完成了关于她们在整个孕期和产后前3个月抑郁症状的问卷。生长曲线分析表明，婴儿的积极情绪随时间增加，这一发现适用于玩耍和进食任务，尽管随着时间推移增长速度减缓。母亲产前和产后的抑郁症状均不能预测婴儿的积极情绪轨迹，但在玩耍任务中，母亲的积极情绪、积极养育和疏离养育与婴儿的积极情绪有关。我们的研究结果表明，产后第一年婴儿的积极情绪有所增加，这表明有抑郁病史母亲的婴儿的积极情绪轨迹可能是恢复力的指标，尽管存在与其母亲抑郁病史相关的风险。此外，本研究强调了养育行为，这些行为可能是预防和早期干预措施的重要目标，以增强婴儿的积极情绪。
