The Tromsø Intervention Study on Preterms (TISP) randomized 146 preterm-born children either to the Mother-Infant Transaction Program (MITP) or to a preterm control group. Previously, significant reductions of child behavior problems and maternal stress have been reported in the intervention group. This follow-up study examines whether the MITP may have affected the longitudinal adaptation between mothers and their children from two until nine years, expressed as associations between different behavioral problems and parenting stress reported by mothers. Associations between internalizing, attentional, and social problems and different dimensions of parenting stress were analyzed in separate models that included effects of time and group status. The MITP did not influence the development of longitudinal associations as no significant three-way interaction (stressgrouptime) was found. Significant stress by group interactions was only found in reports on children's attentional problems when analyzed with parent- or interaction-related stress. Mothers who had participated in the MITP reported weaker stress⁻behavior associations than control mothers. This effect was moderated by two independent variables, namely children's birthweight and years of maternal education for the parent⁻child difficult interaction stress.
特罗姆瑟早产儿干预研究（TISP）将146名早产儿随机分为母婴互动项目组（MITP）或早产对照组。此前，干预组报告称儿童行为问题和母亲压力显著降低。这项随访研究考察了MITP是否可能影响了母亲与其子女从2岁到9岁期间的纵向适应情况，具体表现为母亲报告的不同行为问题与育儿压力之间的关联。在包含时间和组状态影响的单独模型中，分析了内化问题、注意力问题和社交问题与育儿压力不同维度之间的关联。由于未发现显著的三因素交互作用（压力组时间），MITP并未影响纵向关联的发展。仅在使用与父母或互动相关的压力进行分析时，在儿童注意力问题的报告中发现了显著的组间压力交互作用。参与MITP的母亲报告的压力-行为关联比对照组母亲弱。这一效应受到两个独立变量的调节，即儿童出生体重和母亲受教育年限，这两个变量影响亲子困难互动压力。
